2020 TOYOTA RAV4 Engine Problems

Engine light shows on in dash. Stopped to fuel up Car stalled, would not restart Diagnosed fuel pump No prior history of engine issue

What component or system failed or malfunctioned, and is it available for inspection upon request? The flow shut-off valve (coolant leak) failed. This exact component was later included in Toyota’s official recall. The defective part was diagnosed by a mobile mechanic and replaced at a licensed independent auto repair shop. The failed component itself is no longer available, but all receipts and repair documentation are available upon request. How was your safety or the safety of others put at risk? The failure of the flow shut-off valve caused a coolant leak that created a significant safety hazard, as it affected the vehicle’s performance and drivability. This posed a risk to both my safety and the safety of others on the road, which is why I had the repair completed immediately before the recall was issued. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes....

Bought the car with 114k on it now with 115k and I brought it in to Toyota because I have a “engine maintenance required” on the dash now they are trying to charge me almost $1000 because my car has over 100k miles on it and they said they won’t cover it.

Shorted Coolant Bypass Valve, only 14500 miles on my 2020 Rav4, Class action Suit and dealerships want you to pay $800-$1000 to fix problem with a leaky defective plastic poorly designed valve that eventually leaks into the electrical connectors and shorts circuits the valve. There is no recall for this fix and Toyota won't honor the repair. This is a common issue and Toyota Turns a Blind Eye. Error Message: Engine Maintenace Required Call Toyota Dealership. I Did and they give me a song and Dance stating there is no recall for this issue. If i run the heater in the car the message for a few a minutes, then shut off vehicle maintenance warning will reset, once I turn on the AC it will come back on. So, I guess I have to keep the heater on all summer.

Engine coolant bypass valve

Engine maintenance message appeared on my dash. I took it to Big O's Tires and Service a car repair service provider. Upon connecting to the car and inspecting they told me it was a faulty possibly leaking engine coolant valve. The cost to repair is $916. This may cause the engine to overheat and possibly fail due to overheating. This can be very dangerous because it will happen if it does happen while driving which could cause an accident. I have not fixed the issue yet due to a lack of funds but will have to fix it as soon as a get paid because I drive my family in this car and cannot risk catastrophic engine failure. Please have Toyota recall this part as it is a very common failure amongst 2019-2023 Rav4s. A class action lawsuit is underway due to how often this issue arises. Thank you for...

I was driving the car with no issues on [XXX]- made two 30-minute trips with no issues the same day. During a 15-minute drive, the car was fine until I was at an intersection 12 minutes into the drive [XXX] and [XXX] ). I was stopped at the intersection for maybe a minute, and when the traffic light turned green, I released my brake and went to accelerate when I got the following display message: "Engine Stopped Steering Power Low." The engine turned off, and I couldn't get the car to budge in drive or reverse. When I tried pressing on the gas pedal, it wouldn't budge and felt very stiff. I'm thankful this happened at a smaller intersection on a Sunday evening because my car wouldn't start back up and was stuck in the dead center of this intersection. Cars going East and South all had to drive around...

Coolant Bypass Valve failure at 40k miles - 2020 rav4. Replacement at dealership is costing over 800$.

The coolant bypass valuve has failed. There looks to be a class action lawsuit currently underway.

My vehicle Toyota RAV4 Hybrid 2020 began lost power and jerk on highway driving and then following messages appeared: Hybrid System Malfunction, A malfunction in electronic control of engine, throttle or automatic transmission has been detected and check engine light. This happened in September 2024. Toyota dealership replaced the low fuel pressure sensor A after my complaint and vehicle diagnostic, but it did not help.

Coolant Bypass Valve, vehicle is available for inspection. Confirmed by Certified Toyota Dealership. There is a know defect with the Coolant Bypass Valve in 2019-2023 Toyota Rav4. Maintenance Required Light Only Comes on when the Heat is switched to Air Conditioner.

I have a 20202 Rav4 Hybrid and the engine short block has malfunctioned due to no error on my part, in my research there was a recall for this EXACTLY this issues in other cars of this year/make/model - although my vehicle initially did not qualify for this I believe that this in fact related and that Toyota should be responsible for the repair or replacement of the engine. The car is currently with a Toyota Dealership Service Center, Lake City Toyota in Seattle, WA but they have not been helpful. They have given me vague answers and have sent the engine offsite to a machine shop and keep requesting that I pour additional money into fixing an engine that clearly had a manufacturer defect. My car has always been serviced at Toyota dealerships, as suggested by Toyota. My car has never had previous issues until the engine light came...

The coolant bypass valve has been failed prematurely therefor engine heat up and there is a warning on my dashboard that say "engine maintenance required"

at only 55k miles my 2020 toyota rav4 has shown an “engine maintenance required” sign. not to be mistaken with general maintenance. apparently this is a widely common issue where brand new toyotas are having cooling bypass valve issue. however concerningly so, because there are no recalls for this problem yet seemingly every rav4 has this problem? how is there no recall, everyone is paying out of pocket for essentially poor manufacturing, its outrageous, also considering the part itself is under $100 but some dealers are charging anywhere to $600-$1300. it’s predatory and outright wrong.

Check engine light came on and noted a malfunction in the electronic control of the engine, throttle or transmission. When taken to the dealer they found code P012807 related to engine cooling and suggested a replacement of the thermostat. This part should have a life of 100k or 8-10 years and car currently has less than 60k miles and 4 years old. Asked the dealership about known recall 20TA04 - for engine cooling recall but they insisted my car was not impacted. This is a safety issue as it could result in overheating of the engine leading to fire hazards.

My Toyota 2020 RAV4 has a dangerous design flaw. It rolls when turned off and in drive mode. For example, my driveway is on an incline, and a couple times I have pulled into my driveway, gotten distracted, and I forgot to put the car in Park. When I hit the on/off button, the car rolls backwards, accelerating due to gravity. If you're not quick, you can end up rolling out into traffic, or running someone over that is behind your car. All the other cars I've ever owned didn't roll when the car was turned off unless you were in neutral. I believe this is a design flaw because I've spoken to a few other RAV4 owners that have experienced the same thing, and on one occasion, I tested it on another RAV4 and it was the same. I can see this being very dangerous. If you are standing...

Engine Maintenance Light on. After inspection at dealership, the cause was determined as Coolant By-pass valve stuck closed

Broken- Coolant bypass valve My safety was put at risk as the coolant bypass value broke leaking coolant over my cars electrical components and not keeping my engine cool. This could have resulted in my engine, overheating, exploding while operating the car and putting my life at risk. Also “engine maintenance alert” that couldn’t not be dismissed by the driver, obstructed the view of my dashboard. This problem was confirmed by the the Toyota dealership There is currently a class action lawsuit against Toyota for this specific issue.

I have had an "Engine Maintenance Required" warning light on since I purchased the vehicle (used) and have had it checked out by my local mechanic and the Toyota dealer. It is due to the coolant bypass valve malfunctioning. Apparently this is an extremely common issue according to the class action lawsuit and should NOT be put on the customer to pay for this when my odometer has not even hit 60k. A recall needs to be issued for this once and for all.

Coolant Bypass Issue. Engine Maintenance and contact dealer on the dash board.

The coolant bypass valve is needing to be replaced. The vehicle only has 52k miles and just happened after warranty.

While driving with the air conditioner on a message appears on the instrument panel ENGINE MAINTENANCE REQUIRED. From researching this message on the internet it appears this is due to an engine coolant bypass valve problem. From this internet search it appears to be happening to many other peoples Rav4. The cost of having this valve replaced appears to be close to $1000. It appears that this problem is a common thing. Toyota needs to have a recall on this problem. Most people report this happening at various mileage.

Premature coolant bypass valve failure. Vehicle has less than 70k miles, but past warranty, "Engine Maintenance Required-See Dealer" light randomly came on one day and would not go off. Scanner pulled no codes as to what the issue would be. Found out it is a known issue as hundreds, if not thousands of Toyota drivers, have experienced this and that specific warning message indicates that it is due to the coolant bypass valve having failed. Clearly this is a known issue.

Maintenance light is keep showing even after the oil change. After the inspection, mechanic found that it is due to Coolant Bypass pipe/hose. I didn't see a recall but I had to get it done before it get worse. It cost around $500 to change the Coolant Bypass pipe/hose with labor. Hence, I reporting to escalate it and requesting for reimbursement. Thanks.

After only 35k miles the car start showing a failure in the coolant by pass valve that could cause major failure of the engine. It has been reported that it is an ongoing situation with most 2020 rav4. The repair is not covered by warranty and it cost over $700.

I noticed an “engine maintenance required” message on my dash when driving home yesterday. I took the car to the dealership today to have it inspected. I was told I need to “replace the engine coolant bypass valve malfunction” for $738.31. Even though I only have 38,984 miles on the car I was told it was outside of the basic warranty and was not covered by powertrain warranty. When I looked online on several Toyota Forums I noticed other 2019/2020 Toyota RAV4 owners were reporting the same exact issue. I believe this warrants an inspection to see if a nationwide recall is needed and Toyota should cover the cost and refund any and all out of pocket expenses. I’ve driven Toyotas my entire adult life and have never had any issues like this before. It’s very disappointing.

Engine Maintenance Light: Dealer found codes 48257 for coolant bypass valve short to open

The engine coolant bypass valve requires replacement. This could result in engine failure.

2020 RAV 4 little under 34,000 miles. Coolant bypass valve needs to be replaced. “Engine maintenance required visit your dealer” takes place on dash and cannot be cleared.

Air coolant bypass valve malfunction. Engine maintenance error message pops up, does not cool properly. Leaking ac fluid. Confirmed by dealership. Costs around 800 to 900 dollars to repair. Parts must be ordered ahead of time. No warning, just message showed up and will not go away. Doesn't let me see the speed I am going on the display since error message keeps popping up every minute.

I have had a Service Engine message on my dash that would return within seconds of my hitting the button to signal I received the message. When I took the vehicle to the dealership I was told it was a leaking coolant bypass valve and would need to be replaced. I was told the cost would be $215 plus three hours of labor. The final cost was $240 for the parts and $709 for the labor. The vehicle only has 31,209 miles on it. As I have researched the part, I have found numerous people have had the same issue within a similar range of mileage.

The problem starts with a service notice for the engine. when they check it at the dealer they say it is the coolant bypass valve and they charge 1000 dollars to fix the problem. a new car is not supposed to have these types of problems. they are making a lot of money by changing this part because there are many cars of the same year and with few miles that come to the Toyota dealer for the same problem.

Engine Coolant Bypass Valve Failed expecting close to $1000 for repair. This is not a normal failing part. 2019-2023 rav4 and corollas have this faulty valve that fails prematurely. It is well documented throughout the internet and forums of people having the same issue. 3 dealerships I have spoken with list this as a well known issue that is common with the car. It throws engine maintenance required sign non stop.

I bought the 2020 Rav4 XLE back in 2019 and had driven for four and half years now. I went to the dealership to get my routine oil change just this Monday July 29th 2024. As usual, the dealership did multi-inspection on my Rav4 and didn't find any problem that requires immediate attention. Two days later, a warning message popped up on the MID screen right after I started the car and read "Engine Maintenance Required". After searching online, calling both local mechanic and Toyota dealership, it happens to be a well-known issue for many 2019-2023 Toyota models including Rav4, Camry, Corolla that the faulty coolant bypass valve has to be replaced. I'm not a car person and I don't know much about cars but I have had the radiator broken while I was driving on my old car due to coolant related issue and almost got me into an...

52,000 miles, and was just informed the coolant bypass valve has failed. This is apparently an issue with ALL 2019~2022 Toyota Rav4 vehicles. It was a known issue to Toyota, using substandard parts. It results in an error message that cant be turned off, masking all other messages, and can only be fixed by a dealer for over $1,000 in costs.

A code for the coolant bypass valve appeared through an independent service center. Warning message shows "Engine Maintenance Required", when air conditioning is turned on and does not go away. Warning message does not show when air conditioning is turned off. I had a independent service center check any damages to the coolant bypass valve, show that the part was faulty. Through various testimonials Toyota Rav4 owners, they also had the same issue. Warning message started at approximately 55,000 miles and has not gone away even after service. Quote for repair goes above $700, although part has been claimed to be faulty and not disclosed.
