2018 TOYOTA RAV4 Power Train Problems

XXX XXX XXX XXX XXX 11/13/2025 National Highway Traffic Safety Administration Office of Defects Investigation 1200 New Jersey Avenue SE Washington, DC 20590 Toyota Motor Sales, U.S.A., Inc. 19001 South Western Avenue Torrance, CA 90501 Subject: Complaint Regarding Torque Converter Shudder – 2018 Toyota RAV4 AWD To Whom It May Concern, I am submitting this complaint regarding a serious transmission defect in my 2018 Toyota RAV4 AWD, specifically a torque converter shudder that has been documented by Toyota technicians. The vehicle exhibits pronounced shuddering between 25–50 mph under light throttle, consistent with the torque converter failures previously acknowledged by Toyota in earlier RAV4 models (2013–2015). Toyota has extended warranty coverage for torque converter replacement in those earlier models, yet my 2018 RAV4—despite showing identical symptoms—has been excluded. The dealership has quoted me $9,000 for a full transmission replacement, even though the issue is well-documented and appears to be systemic across...

The contact owns a 2018 Toyota Rav4. The contact stated that upon entering her carport in an attempt to park(P), the vehicle surged forward without warning. The vehicle blew through the carport's back wall and crashed into her neighbor's fence before coming to an independent stop. The air bags did not deploy upon impact. The contact did not seek medical attention but did sustain soreness in her neck, shoulders, and back. The carport's back wall, a bicycle, the neighbor's fence, and the hammock were all destroyed as a result of the accident. A police report was filed. The dealer was notified of the failure and immediately referred the contact to the manufacturer. The manufacturer was notified of the failure, and a case was filed. The manufacturer informed the contact that an engineer could be sent to a nearby dealer or independent mechanic to perform an investigation into the defect. The...

I have had my car for about 2 1/2 years, never been in an accident or anything .. I take the car for an oil change and when I picked it up they informed me that they ran a diagnostics test that indicated that my transmission was out. They asked if I’ve been in any accidents, but I assure them that I have been any accidents at all. The car has been driving perfectly fine but after that news, the car has been dying out! I don’t travel far in the car or go on road trips so I’m not understanding how the transmission has failed!

The contact's daughter owns a 2018 Toyota Rav4. The contact stated while driving approximately 50 MPH, the vehicle started losing motive power. The contact stated that the check engine warning light illuminated, and the vehicle was vibrating abnormally. The contact heard an abnormal grinding sound underneath the floorboard. The contact pulled over and it was difficult shifting to park(P). The contact turned off and restarted the vehicle; however, the vehicle was not functioning normally. The contact had taken the vehicle to an independent mechanic where it was diagnosed and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired. The contact had taken the vehicle to the same mechanic prior to the failure for two other transmission failures. The contact stated that the failure had occurred three times within 18 months. The manufacturer was not informed of the failure. The failure mileage was approximately...

1. It is not clear what component or system failed. While driving at around 70 mph, after 2-3 hours of driving, there is an audible "clunk" sound from below the car. Typically this is followed by a shuddering of the engine/transmission/power train. The car momentarily looses acceleration/speed. There are typically one or two "clunks" alternating with one to four "shudders." There is no action when depressing the accellerator. At this point I typically pull over to a rest stop or side of the highway to let the vehicle rest, and then re-start the vehicle, which causes the issue to not re-occur when the vehicle is driven again. Yes the vehicle is available for inspection upon request. 2. My safety and others' safety was put at risk by the vehicle not being able to accelerate when the accelerator is depressed. 3. The vehicle has been inspected by multiple Toyota dealers, including...

The contact owns a 2018 Toyota RAV4. The contact stated that while driving at an undisclosed speed, upon attempting to slow the vehicle, she heard an abnormal sound emanating from the front of the vehicle, and the brake pedal required an excessive amount of force to slow the vehicle. The contact also stated that later, while driving at an undisclosed speed, the vehicle inadvertently lost all motive power. She was able to coast to the shoulder of the roadway, where the vehicle was able to be jumpstarted. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the braking system but did not provide a diagnosis in regards to the vehicle's loss of power. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 40,000.

Last week my transmission suddenly and completely failed while driving on the interstate, creating a major safety concern. I was stranded on the interstate for three hours until I could be towed off. The car only has 56,000 miles on it and there were no warnings that there was any problem with the transmission. The transmission previously failed at 7,000 miles and was found to be defective and replaced at the time. How can a car with 56,000 miles on it already have had TWO transmission failures?

Transmission failure at high speed on the freeway during a non shifting period. Transmission automatically downshifted to 3rd gear at speed on freeway and would not reengage properly to higher gears resulting in immediate red line and sudden slow down in free flowing freeway traffic

I have a similar complaint as NHTSA ID Number: 11210210. On several trips over the past few years, while traveling at speeds of 70 mph, my vehicle would have a loud bang and then start bucking and jerking when I briefly let off the accelerator. About 2 weeks ago, I was looking at my speedometer at the time when the bucking started happening. The EV light came on for a brief second and the needle on the charging gage briefly dropped down into the charging status. It seems that the EV motor was trying to engage at speeds causing the bucking. This seems like to be a major concern when traveling at highway speeds. The engagement of the EV motor at highway speeds is like unintended engine braking that possibly lockup the engine and loss of control.

I was driving during work and my transmission went. I could no longer drive forward. I brought my car to Toyota dealership to see about the problem and got a diagnostic test performed, oil change, 4 point inspection and explained that my car is stalling, it’s jerking when I step on the gas and it won’t take off and then just jerks my head. It’s making these rattling noises when I step on the gas. They stated it’s the massive airflow system and throttle body work: I explained I just changed the massive airflow sensor so it can’t be that but he stated that they need to order the piece and I need to come back Friday which I did so they can fix the problem. Not even a week later my transmission is gone and I missed over a week of work. I did have a mechanic look at...

Bought brand new 04/02/2018. First battery died July 2018. First cooling system needed replaced December 2019 due to overheating issues. There has been 7 battery replacements, about two each year, the two most recent was July 2022 and October 31, 2022. Second cooling system replaced December 2022 due to overheating issue. Damaged engine and needed to replace engine. Other issues have been stalling while driving in traffic; stalling while turning and at traffic lights. Was told by Toyota technician that it was due to extremely low oil. I asked why no low oil light came on and he stated it must be damaged but too expensive to repair. My wife and I had our safety at risk due to stalling in traffic and being stranded due to dead batteries. One night we had to sleep in a grocery store parking lot as a tow truck wasn’t available that night. Toyota...

Since I bought the car in 2018, the car has stalled two times while I am driving on the road. That was very dangerous because other drivers almost hit me from behind. The first time I had the problem, the Toyota dealer told me that it was likely caused by bad gas. It happened again this time today. I am bringing it to the dealer again, but likely not able to get a solution. At the same time, I am scared of driving it, yet I need to drive it for work and other necessities. Happened at 32k in August 2020, and 55k in January 9, 2022.

The contact owns a 2018 Toyota RAV4. The contact stated that upon exiting a parking lot, with the brake pedal depressed to the floorboard the vehicle independently accelerated without warning. The contact was forced to engage the parking brake to stop the vehicle. Once the vehicle was stopped, the contact was able to resume normal driving. After the initial failure, the contact experienced the failure on two separate occasions. The contact had taken the vehicle to the dealer however, the mechanic was unable to diagnose the failure. The vehicle remained in possession of the dealer. The manufacturer had been notified of the failure and informed her that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 18,000.

This is the second time it has happened, the car completely shut off and nothing worked. The first time does happen our battery was two years old and we were told to change it. After changing the battery the car worked. Six months later the car completely shut off while driving. AAA came and said it was not an issue with the battery but rather the wiring. He played around with the wiring in the car somehow turned on. This is very dangerous because it happened on the freeway. There are some fault with the wiring on this model.

The Toyota RAV4 2018 car acceleration went out of control and crashed into a retaining wall. The airbags exploded and the steering wheel airbag burst. The car was totaled and is with State Farm. I was blessed to still be alive the car speed out of control on its own. I tried to push on the brakes but the car kept going. The accident could have been worse. No one else was injured only another car was hit. I did reach out to Toyota and they said it could take 4-6 weeks for someone to look at the car. I reach out to the dealer and waiting to hear back from the dealer. The police department issued me a ticket, I have court on July 23, 2021. State Farm insurance declared the car a total loss. No warning lamps or messages. The first same incident happened on April 3, 2021,...

THE VEHICLE DOWNSHIFTS 2X AT 40 MPH INTO A GEAR WHICH MAKES THE CAR LURCH AND THE RPMS GO FROM 2000 TO 4000. HAPPENS DURING MILD ACCELERATOR DEPRESSION. IF YOU ROMP ON THE GAS THIS DOES NOT HAPPEN. WHEN IT DOES UPSHIFT THE ECO LIGHT COMES ON BUT THEN IT UPSHIFTS AGAIN. THE SENSOR DOES NOT SELECT THE RIGHT GEAR FOR THE LOAD.

I PURCHASED MY RAV4 BRAND NEW MID/LATE YEAR 2018. IN DECEMBER AT APP. 10000 MILES I STARTED HAVING ISSUES WITH THE GEARS. SHIFTING FROM PARK TO ANY GEAR I WOULD HEAR A LOUD BANGING TYPE NOISE AND THE ENTIRE CAR WOULD JERK. ALONG WITH THAT ISSUES I HAVE NOTICED A DELAYED ACCELERATION AT GREEN LIGHTS SOMETIMES TO THE POINT WHERE I GET A TRACTION CONTROL LIGHT ONCE IT HAS KICKED IN OR EVEN JERKING WHILE FINDING THE CORRECT GEAR TO BE IN. ONCE I HAVE ACCELERATED AND LET OFF THE GAS, AND THEN RETURNED TO THE ACCELERATION PEDAL AFTER BRAKING OR JUST MOMENTARILY RESTING MY ANKLE WITH THE CAR AT SPEED, THE CAR WILL "FISH FOR GEARS" LIKE IT CANNOT DECIDE WHICH GEAR THE CAR SHOULD BE IN. WHEN GOING DOWNHILL AND LETTING OFF THE GAS IT WILL DOWNSHIFT, CAUSING THE CAR TO JERK. ALL THESE ISSUES HAPPEN OFTEN BUT...

THE VEHICLE JERKS AND MAKES LOUD NOISE WHEN THE EV MODE TURNS ON MOMENTARILY AT 60 MILES PER HOUR. THIS USUALLY HAPPENS WHEN GOING DOWN HILL AND PRESSING ACCELERATOR AFTER RELEASED FOR A FEW MINUTES. THIS DOES NOT ALWAYS HAPPEN BUT WHEN IT DOES, FEELS LIKE THE REAR TIRE HAS BUSTED AND THE CAR IS BEING FORCED TO MOVE. IT HAS HAPPENED MULTIPLE TIMES NOW AND I HAVE REPORTED IT TO TOYOTA BUT THE DEALER CANNOT REPLICATE THE PROBLEM. IT HAS OCCURRED AT LEAST 8 TIMES SO FAR SINCE I BOUGHT THE VEHICLE IN SEPTEMBER 2018.

THE ENGINE DIES TO IDLE SPEED AND THE CAR STOPS OR SLOWS DOWN. THE DEALERSHIP SAYS THIS IS BECAUSE OF A 4 CYLINDER ENGINE CONNECTED TO A 6 SPEED TRANSMISSION. THERE HAVE BEEN SEVERAL TIMES WHEN I WENT TO ACCELERATE TO GET ON THE EXPRESSWAY AND THE CAR SLOWS DOWN. THE PEOPLE BEHIND START BACKING UP AND ARE MAD. I HAVE TO PULL TO SIDE AND LET THEM BY. MY CHILDREN ARE INSTRUCTED TO SUE TOYOTA IF MY WIFE AND I DIE IN A CAR ACCIDENT. THIS HAS TO BE A COMPUTER GLITCH. ITS VERY DANGEROUS.

FROM A DEAD STOP WHEN ACCELERATING THE VEHICLE WILL NOT SPEED UP IT ACTS LIKE ITS IN 6TH GEAR. TO GAIN CONTROL I NEED TO PUSH THE ACCELERATOR TO THE FLOOR & THEN IT SPEEDS UP ALMOST UNCONTROLLABLY. THIS HAPPEN AT 12 TIMES. SEE MY COMMENT BELOW THAT I SENT TO TOYOTA CORPORATE OFFICE. I HAVE WANT I CONSIDER A SEVERE SAFETY ISSUE WITH MY 2018 RAV4 ([XXX]). UPON ACCELERATING FROM A STOP THE VEHICLE WILL NOT SPEEDUP IT ACTS LIKE IT IS IN 6TH GEAR TO GET IT GOING I HAVE PUT THE GAS PEDAL TO THE FLOOR AN THEN IT SOMETIME SHOOTS AHEAD ALMOST HITTING A VEHICLE IN FRONT OF ME. RECENTLY IT HAPPENED 3 TIMES IN A ROW TWICE I GOT IT TO RECOVER BUT THE THIRD TIME I NEEDED TO PULL OF THE HIGHWAY & RESTART THE ENGINE. THIS HAS HAPPEN AT LEAST 10 TIMES. PHILLIPS...
