2019 TOYOTA RAV4 Electrical System Problems

The contact owns a 2019 Toyota Rav4. The contact stated that while seated in the vehicle, while the vehicle was parked, there was an abnormally strong plastic burning odor inside the vehicle. The contact stated that a top light was plugged in the trunk, but the light was turned off. After opening the trunk, the contact became aware that the wiring in the trunk had overheated and burned the laundry that was inside the vehicle and the rear passenger's side seat. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 129,000.

Toyota RAV4 LE gas pump burst and caught fire leading to total fire damage along with major water damage from the firefighters putting out the fire. The vehicle was idle for hours at the time of explosion of the fuel pump. This was a major safety hazard/risk especially being that myself and two others were minutes away from going out to the vehicle before it all happened as I was getting ready to take a friend home for the night. A claim representative will look into this matter in coming days.

The contact owns a 2019 Toyota Rav4. The contact stated while driving 70 MPH, the vehicle experienced a loss of motive power. No warning light was illuminated. The contact managed to push the vehicle over to the shoulder of the road, and the vehicle was towed to the residence. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

While traveling back from out of state, the fuel sensor and fuel gauge failed causing me to run out of gas when the fuel gauge stated I had just a tick under a 1/4 tank of gas left and the app read 35 miles left. While driving on freeway at freeway speed, the car sputtered, bogged down and then stalled, placing me in a very dangerous situation broken down on the shoulder of the freeway in the desolate country at night with semi trucks and cars flying by at estimated between 70-80 mph. While stalled and waiting for help, all the lights except the hazard flashers went out. The Sheriff assisted and added 2 gallons of gas that finally got the car restarted and I was able to get to the gas station which was 1 mile ahead of where I had been stranded. I kept filling the gas tank...

My 2019 Toyota RAV4 experienced a dangerous electrical and transmission failure that ultimately caused the vehicle to stall while driving and made me lose control. For several weeks before the incident, the vehicle showed subtle hesitation when accelerating but no warning lights. After the car stalled and spun out coming off the Ben Franklin Bridge onto I-76 near downtown Camden, police responded, confirmed the vehicle had unexpectedly shut off, and verified there was no crash damage. I later brought the car to the Toyota dealership, where they discovered corrosion on the battery cable, failed ABS sensors, and a weak battery. I paid $668 for a new battery, new cable, and ABS sensor repairs. At that time, the dealership did not inform me of any transmission issues and released the vehicle back to me. I made it only a short distance up the road before realizing the vehicle could not accelerate...

One week ago one section of the heated steering wheel was very hot. So much so that I could not touch that area. I took it to the Anderson Toyota dealership in Rockford today. On the way there, I turned on the heated steering wheel, and it started smoking. They said they couldn’t find what was wrong with it, and to replace it would be $1800 because it isn’t in warranty. They suggested I not use it.

Vehicle states engine maintenance required. Is a consistent reoccurring problem according to dealer. System failure due to manufacturer always puts the user at risk.

Got a "Hybrid System Malfunction" notification on my dash and took it to the dealer. I was notified that my high voltage hybrid cable is corroded, and that the vehicle is unsafe to drive. I understand that customer support program 22TE09 exists for this problem, but because my vehicle has over 100,000 miles, it is not covered. If this is a safety issue that Toyota has acknowledged and admitted is an issue, there should be a complete recall. I was FORCED to get the work done at a dealer because Toyota has a hold on the part. I attempted to get an independent garage to do the work, but they were not authorized to even purchase the parts necessary. Ultimately I had no choice but to spend almost $5000 for a safety repair on a 2019 vehicle that Toyota themselves have admitted to the engineering mistake, while also making it...

The DCM is nonfunctional, which renders the safety connect features of the car inoperable. Additionally, the Bluetooth microphone is powered by the DCM causing the driver to have to switch the call output on their phone manually taking their focus off the road. This seems to be a widespread issue with many reporting this on online threads and Toyota offering many internal service bulletins. To me this is a major safety concern that is extremely costly to repair.

I am submitting this complaint regarding a recurring issue in the coolant bypass valve of my 2019 Toyota RAV4 XLE Premium. Although there was no check engine light, the vehicle displayed a persistent warning: “Engine Maintenance Required – Visit Dealership.” This message repeatedly appears on the instrument cluster and blocks critical driving information, including the speedometer, fuel economy, and other key displays. Even when the driver manually cancels the message, it returns within minutes. This creates a constant distraction and obstructs visibility, which poses a safety risk during driving. I took the vehicle to the dealership, where they diagnosed the issue as an internal short circuit in the coolant bypass valve and retrieved diagnostic trouble code P268115. This code relates to a malfunction in the valve’s electrical control system, which affects the engine’s ability to regulate temperature effectively. Toyota currently offers a Customer Support Program (CSP) for the coolant bypass...

The vehicle began displaying intermittent warning messages and slipping into "Mud & Sand" mode without cause. Later, multiple dash lights illuminated, including 4WD malfunction, check engine, and coolant system warnings. The vehicle became undrivable due to overheating. Dealership diagnostics indicated a failure in the coolant bypass valve actuator the electronic water pump was receiving a signal but not responding, resulting in loss of coolant circulation and overheating. There may also be a shorted control panel causing related system failures. This problem has been confirmed by a Toyota dealer, and the vehicle remains at the service center pending resolution. The issue appears related to a known Customer Support Program (CSP 24TE04), which covers the coolant bypass valve actuator. There was no prior accident or abuse of the vehicle, and the vehicle only has 52,000 miles. Safety was compromised due to unexpected power loss and overheating while in motion. The issue has...

Started normally, but had a message on the screen saying “Check Fuel Cap.” I needed gas anyways, drove about 3 minutes to the gas station, turned engine off, put gas. Turned engine back on and within 3 seconds it shut off. The screen displayed “engine stopped- Power steering low.” I tried a handful of times to start, it did not. After 20 minutes and some rest, it started. With no more messages. Battery and alternator were tested, both were good.

The contact owns a 2019 Toyota Rav4. The contact stated while driving 60 MPH, the vehicle started swaying in and out the lane. There was no warning light illuminated. The contact linked the failure to the lane keep assist feature. The contact stated that the failure persisted. The contact continued to drive the vehicle and the vehicle violently jerked, forcing the contact to pull over. In addition, the contact stated that the vehicle was accelerating unintendedly upon releasing the accelerator pedal. The contact immediately pulled over and turned off the vehicle. The contact turned off the lane assist feature and proceeded to drive the vehicle at a slow speed. The contact stated that while accelerating above 35 MPH, the abnormal jerking returned. The vehicle was not repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 62,000.

While driving or stopped at a light, car will switch drivings modes to “mud and sand” turning off the vehicle stability control and pre-collision system warning light will illuminate. After pressing desired mode, car will switch back to “mud and sand” at varying intervals resulting in me pressing the desired mode constantly while driving.

A Hybrid System Malfunction warning appeared about 1 week ago. The car was taken to the Toyota dealer who said that the car was safe to drive and that they would need to order a part and it will probably be weeks before they get it because so many other cars have the same problem. Three days later the car will not start with several errors including Brake Power low, PKSB Malfunction, and Precolllision System Malfunction. Toyota is not providing any coverage for any of our repair, car rental or now the need to tow the car.

The contact owns a 2019 Toyota Rav4. The contact stated that when the vehicle was started, the vehicle was shaking abnormally. The contact stated that the overheating, parking brake, cruise control, maintenance required, and check engine warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed that there was a misfire in cylinder #2, and that coolant was leaking into the engine. The contact related the failure to NHTSA Campaign Number: 20V064000 (Engine and Engine Cooling); however, the VIN was not included. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was unknown.

I have been experiencing water intrusion with my vehicle, I first noticed it by a mildew smell. Acknowledged under Toyota’s Customer Support Program 22TE05. This water leak has led to multiple secondary issues, including: Interior water damage Clogged A/C drainage system Sunroof drainage issues I reported this issue to a Toyota, but they denied repairs under 22TE05, claiming the issue was only due to a sunroof leak and clogged drains. [2/14] – Took my car to AutoNation Toyota due to a persistent water leak. The dealership diagnosed the issue as a clogged sunroof leak and clogged drains but did not provide clear documentation that they properly inspected the roof rail gasket. [2/18] – Dealership denied repair under 22TE05 but then stated they could replace the roof rail gaskets if my insurance paid for it—which contradicts their claim. [2/18] – I escalated my case to Toyota Corporate for review, but I...

The contact owns a 2019 Toyota Rav4. The contact stated that upon starting the vehicle, the messages "Parking Brake Malfunction", "Secondary Brake system Malfunction”, “4WD Malfunction", "Lane Assist Malfunction", "Pre-collision Malfunction" and messages indicating malfunctions of the electrical system, the engine throttle, and the transmission were displayed. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where a spark plug and ignition coil were replaced; however, the failure recurred. The vehicle was taken to the dealer, where the contact was informed that all the spark plugs and ignition coils needed to be replaced prior to the final diagnostic test. The vehicle was not completely diagnosed and was taken back to the mechanic, where a specialist used a camera to diagnose that there was coolant intrusion in cylinder #4, due to a fractured cylinder head. The mechanic related to the failure of NHTSA Campaign Number:...

On 01/29/2025 at around 5:30pm I was driving home from work when suddenly the car stalled. I was going about 45 mph on a secondary to Lane Highway that was completely black because there are no street lights in that area. There were all kinds of warning lights flashing on the dash. I let my car drift to the shoulder was able to break and put it in park. I tried turning the vehicle back on but it would not start. My cell phone showed no Wi-Fi connection but I know the area very well and I knew I could walk several feet to a connection. Therefore spite concerns for my safety I had to leave my vehicle in order to call for help. I walked about 30 ft in the pitch black on this highway dressed in dark clothing on a shoulder that was very narrow. There was a...

The vehicle suddenly started to smoke and burn by itself when driving on the super crowded highway. I immediately stopped the vehicle and found that the burning site was the bottom of the front-left head of the vehicle (please see the images attached). The mechanician I visited after judged that the fire may due to failed electrical parts or system. He suggested to visit a Toyota dealer for recall. However, the Toyota dealer (Crown Toyota, 1201 Kettering Dr, Ontario, CA91761) declined my request with the reason that my vehicle has passed warranty time. The vehicle was just inspected in the Toyota dealer a few days ago. The dealer's inspection report shows that the vehicle does not have any problems besides suggesting to replace tires and front brakes.

The Data Communication Module has failed in my vehicle. This causes several major distractions and increases the risk of an accident. The media screen in the center of the dashboard will send an alert message every 15 seconds saying that ‘the connected device is not compatible’. At night, this alert message is especially bright and distracting. The lights on the SOS button are constantly blinking. More significantly, the SOS button does not work anymore. The only known solution to this problem is either to disconnect the DCM, or to pay more than $1300 to replace it.

I am writing to file a formal complaint regarding a manufacturing defect in my vehicle and the refusal by Toyota to honor its responsibilities for repair despite clear acknowledgment of the issue. In October 2024, I discovered a small water leak from the roof of my vehicle. I attempted to schedule an appointment with the nearest Toyota dealer, but the timing of their available appointments conflicted with my work schedule, and it was not possible for me to get a timely appointment. In an effort to mitigate the leak, I tried to fix it myself until I could get the vehicle to the dealership. Upon visiting the dealership, I was informed that the issue was a manufacturing defect, but they refused to repair my vehicle because I had attempted to fix the issue myself. This worsened the leak, as they did not return my vehicle to its original condition. I...

My car frame floods every time it rains. This flooding includes my sunroof drain clogging. As a result of the water retention in my car’s frame, my cars safety system controller units are being corroded and thus I DO NOT have any reliable safety monitoring system. I have looked into this and this a COMMON complaint for Toyota 2019-2021 Rav4 sunroof cars. I have had the sunroof drain cleared multiple times but the issue remains. So far it has impacted my tire pressure safety monitoring systems. This is a MAJOR safety issue as the electrical safety monitoring system controller units are NOT properly functioning as a result of poor water drainage.

I have been told by the Toyota Arapahoe dealer that the DCM in the car is bad. All the services the DCM supposedly provides have NEVER worked on the car, leading me to believe it has been faulty from day one. These include all safety assistance features.

Initially thought a seal on the windshield was faulty, so contacted the business who replaced the windshield. Business owner came to owner’s house Mon, Nov 4, 2024. He did a thorough inspection of all areas where water was identified by owner (dash, under the dash, on the driver side floor) and confirmed it was not the windshield. He then inspected the roof rack and determined the roof rack was defective and leaking water from the ceiling of the vehicle, down into the dash, and ultimately onto the floor. He recommended contacting Toyota because this was a known issue. By 12pm on Mon, Nov 4, 2024 owner contacted Toyota alerting them to the issue. An appointment was made to bring the vehicle in for inspection on Mon, Nov 11, 2024. Owners do not have a garage or carport, so a canopy was pitched over the car in an effort to prevent...

A distracting message “a connected device is not supported” flashes on my console screen every 10 seconds. This occurs when there are no device or cable connected. It blocks the clock and driving directions if I am projecting them through CarPlay. The SOS emergency system lights flash back and forth from red to green.

Defective coolant bypass valves on my 2019 Toyota RAV 4 have caused coolant to leak out of my vehicle’s closed-loop coolant system, harming its ability to properly regulate engine temperature. Eventually the message “Engine Maintenance Required Visit Your Dealer” appeared on my dashboard indicating an issue with the engine. An internet search of this error message on the 2019-2023 Toyota RAV4 and Corolla models shows this is a widespread defect, affecting hundreds of Toyota owners. A class action lawsuit has been filed against Toyota regarding defective coolant bypass valves in the 2019-2023 Toyota RAV4 and Corolla models [XXX] et al. v. Toyota Motor Sales, U.S.A., Inc) but Toyota has still not addressed this defect with a recall. Attached is a copy of the mechanic invoice I just paid to replace the defective coolant bypass valves on my 2019 RAV4 as the engine was not maintaining temperatures appropriately and in risk...

SUV showed on the display that there was a Hybrid System Malfunction. SUV is in a Toyota dealership shop in Aberdeen, WA. I called the shop immediately when the notification came up. Was advised that it was OK to drive until check engine light came on, which it didn't. I only drove to work amd back after the notification and call to shop. The cruise control would turn off and I'd be notified on the screen. Again was told ok to drive until check engine light came on. Approx a week after calling shop, SUV would not start before going to work. Had to be towed to shop. Potential safety issue if this happened while driving on highway or while in a rural/wooded/off main road area with no cell phone service. I was told my the shop that another SUV had recently had the same issue. Shop says that the...

My rear backup camera has intermittently worked for almost 2 years now. I was not included in the recall Toyota K05 / NHTSA campaign number 19V576, but I do believe I should be included as the issue describes the issue I have been having. Dealer advised me I need a new camera but the camera works from time to time. The dealer could not replicate my issue in Oct 2023. I’m still having the issue and it has gotten worse.

“Engine maintenance required” maintenance light on dashboard. Very common issue within RAV4s. This message blocks the odometer on the dashboard when visible. It shows warning lights on the display as well. The part that needs replacing is a “coolant bypass valve”. My dealer wanted nearly $1000 to replace this part, and told me this part was on back order nationwide. My car begins to overheat after 1.5 hours of driving. The dealer said to pull over when operating my vehicle and it begins to overheat. This problem is an inconvenience as I commute to work in a busy city. This problem was first presented last week after my scheduled oil change with my local dealer. The next day (5/17/2024) the light came on my dashboard—unable to be removed. I first brought it into the dealer for a diagnostic on 5/20/2024, this is when they diagnosed a coolant bypass valve. I...

Coolant Bypass Valve leaking onto electrical systems. If not fixed, electrical system will fail. Toyota is aware that it's a common problem.

The vehicle is a 2019 Hertz rental RAV4 Hertz. On October 12, 2023, when I moved the gearstick to reverse the vehicle accelerated uncontrollable at extremely high speed and crashed into a wall. Braking did not stop the vehicle.

Car is shaking when turned on. Will stall if car is not shifted to gear sometimes. When AC is on, car will jump rpm. car acceleration is weak and will jump to 5-6k rpm. car also smells burnt sometimes when driving. car also smells like gasoline sometimes. car does not hold proper amount of gasoline.

My car ran a message of “ Maintenance engine required” and it turns out the COOLANT BYPASS VALVE has gone bad. When turning the AC on the message appears, but went off the message doesn’t appear.

Hybrid Harness Malfunction. As reported on FaceBook by my wife to [XXX] of LIA Toyota: "Well my husband's RAV 4 wasn't safe and you knew it. And corporate knew it. You are in the business of saving lives by informing your customers when you find a defect in your cars. This faulty harness is dangerous. And the repair is costly and there aren't many of these parts available to make the repair. You put my husband and countless others in danger. Shame on you." Not only has the problem been confirmed: On May 11th, I received a letter from TOYOTA Motor Sales, USA, Inc. entitled, Certain 2019-2022 Model Year Rav4 Hybrid Vehicle (AWD Only) Coverage for High Voltage Floor Under Wire Harness and Rear Traction Motor Cable Corrosion CUSTOMER SUPPORT PROGRAM 22TE09 NOTIFICATION... There was a YouTube Video made by [XXX] about this problem A YEAR AGO entitled, "CableGate," AND...

Engine Maintenance Required light came on. Got it checked out by Toyota Dealer and the coolant bypass valve needs to be replaced. It seems to be a common problem with RAV4s.

The DATA COMMUNICATION MODULE - the DCM does not work properly. At first the Mic for the phone did not work when using the phone , then my clock and information page on the screen went in and out. I went to a dealership and they charged me $150 for diagnostic and now $1300 to fix. This is a vital piece of equipment for using communication devices hands-free. There is already a campaign to 21-22 RAV 4 models, and I believe this is the same issue only to the 2019 and 2020 also. Here is the link to the campaign. Please help me. https://www.toyoheadquarters.com/threads/2021%E2%80%932022-toyota-vehicles-dcm-data-communication-module-reprogramming-special-service-campaign-ssc-22tc01.2566/

Vehicle is switching to mud and sand mode on its own, which according to a quick google search is a common electrical problem. Possible cause listed by other drivers is a roof rail leak. Upon inspection I see water stains on the inside of my headliner where the roof rails sit. So confirmed roof rail leak. I have not yet had this looked at to learn the full extent of the damage.

Received multiple malfunction alerts. BSM & RCTW. Other safety features also inop. Dealership told me it was due to non-factory installed Cross Bars, faulty gasket allowed water into vehicle and flowed down onto the Engine Control Module. There was no way the amount of water said to have been in vehicle could have come from that 1 gasket, over 1" above roof. After $825+ and removal of cross bars water still leaking into car. Concerned issue will re-occur making safety features worthless, as well as damage side air-bags. These issues would all need to be corrected via out-of-pocket expense. Believe the issue is design flaw from Toyota.

Roof rack design and grommet failure allows for water to flow into cabin headliner and down a-pillars and other areas where curtain airbag and other electrical components are housed. This can cause malfunction and/or failure of the vehicles crucial functions at any given moment. A class action lawsuit is filed on this. You need to step in and make it a recall and hold toyota responsible.

Outside water (rain, carwash, etc) is leaking through the roof into the A-pillar and C-pillar areas and into the interior. Water is likely entering the air bag components in the front A-pillars on both sides, potentially causing a safety issue. Also concerned that water could be entering the electrical components in the dashboard. When researching the issue, found multiple complaints of this issue and also at least one class action lawsuit. Dealer is pushing back on covering this under the "Certified Pre-owned Comprehensive Warranty". https://www.carcomplaints.com/news/2023/toyota-rav4-roof-rail-leaks-class-action-lawsuit.shtml https://www.classaction.org/toyota-rav4-leaking-lawsuit https://www.motorbiscuit.com/lawsuit-alert-toyota-rav4-roof-leak-causes-water-damage-electronics-airbags/

Driving home from work on 3/25/23 at 9:15 pm my dash lights starting going on and off flicking. “Power steering malfunction. Steering power low visit your dealer” “abs” also multiple dash lights came on at the same time. Brake light steering light. Got home and took video while parked to safely show the issue

DCM unit failed. It controls Toyota safety connect and all communication to Toyota. If I were to be in an accident the SOS button to get help is inoperable. This has been reported to Toyota. This is a problem for nearly all the DCM units across the entire Toyota platform. Toyota is only willing to fix these defective DCM units under a 3 year 36k mile warranty. Considering the extent of the failure of these units across all their vehicles I believe Toyota should fix this systemic problem with their safety system outside their traditional warranty. Thanks

A couple of months ago, I noticed water had somehow entered the inside of my car, collecting along the interior roof panel and inside the C-pillar close to the top of the driver door. I did a little research to see if I could figure out what the cause of it was. I found that many other owners of 2019 and 2020 Rav4's had similar problems. Their findings indicated that Toyota had equipped poor quality gaskets, along the the area in which the roof rail trim were fastened to the roof of the car. I also read that this problem could be fixed by the owner, but was unaware that the water leakage would come in contact with electrical components. Yesterday, I experienced first hand the result of this situation. When starting my car, the display board was indicating a multitude of warnings for system malfunctions. These included power steering...

The engine on my Rav4 suddenly stopped without any notification while I was driving it on the freeway. I could have been severely injured from the risk of being rear ended by vehicles behind me. I have experienced this twice now, and both times, I have been on a busy highway in the middle of rush hour traffic. While driving, the engine would start sputtering and the vehicle will jolt and shake, eventually causing a warning message to appear that says power steering low, engine shutting off, place vehicle in Park. Then, when I turn the engine off, and try to restart it, it would flash a message that read Not ready to drive. After towing the vehicle to a service department, the vehicle would start up like normal, and the techs could not get vehicle to duplicate the issue. No codes would come up when they place it on...

Car randomly switches into different driving modes, BSM and anti collision goes off while driving. Seat warmers randomly come on high and can’t be turned off. Dealership identified water damage from leaking roof rack resulting in mold and electrical damage. Possible damage to airbags as water leaking into the pillar at front window. Many instances documented online.

I was recently driving my 2019 RAV4 when it started switching to mud and sand mode and turns of all my safety features. This would occur at random when I was parked and driving. I was able to find several discussion boards about this issue by searching ‘ 2019 rav4 switching to mud and sand mode.” I took it to the dealership and they discovered that there is a leak from the roof racks that is causing water to get in my car and is now impacting the driving ability and safety features on this car. I was able to find many discussion boards and even YouTube videos on how to fix this issue by searching “2019 rav4 roof rack leak.” It was reported in Australia, Japan, Taiwan, and the US. Many reported they had this issue fixed for free under warranty but now warranty has run out on the...

I have had my RAV 4 since it was brand new. Today while i was driving, the mud and sand screen popped up automatic with traction control light, later i was able to turn it to normal then the light would go off for a while and it comes back again. It all happened while i was driving in I 355 going down to Lemont, IL from Palatine IL. I had the same problem but not with the mud and sand but with snow back in 2019 when it was a brand new, took it to a dealership and they said they have never seen like this before and they just reset the computer and it went off. I am pretty sure when I first bought it, even i push each and every button of either snow, sports or mud, the traction light wouldn’t come off. While driving on i...

We have a 2019 RAV4 the mud and sand mode kept randomly turning on in the highway. The car loses traction when it goes into the mode. Toyota claimed they are not responsible. This is a very danger issue.
