Selected complaints filed with NHTSA by 2021 Toyota RAV4 owners, lightly cleaned up (personal details are redacted by NHTSA).
My wife was pulling her car into a parking area consisting of a few small storefronts. When pulling in, the brakes completely failed as did the forward collision warning system and the automatic emergency braking system. As she continued to press the brake pedal it just went to the floor of the car. The end result was that the car struck one of the storefronts causing damage to the building as well as her car. Fortunately the store was closed at the time and no one was injured, nor was she. There were not any warning lamps or messages prior to the brakes failing. The brakes worked fine in the approx. 15 minute drive prior to the accident. I realize that drivers sometimes press the accelerator in error instead of the brakes and I can assure you that this was not the case (we wife is not elderly and is a very safe driver). …
While driving to friends house, the collision warning popped on screen 1 or 2x but no vehicle was close to front of the car. When I turned into driveway and pulled onto yard to park the collision warning went off and red screen flased and I tried to brake but brakes would not depress. The car suddenly lurched forward quickly and I tried to steer away but it slammed into a line of cars with great force. I crashed into the parked car in front of me with such force it pushed a line of 4 cars. I had mild issues after crash: Whiplash, neck pain, head pain, and soreness. The RAV-4 had passed inspection with the dealer with no issues, The car had less than 15K miles driven. The collision warning lights seemed to start to have issues the day of the crash; approximately 15 min before the crash. …
While waiting at a red light with my car stationary, the lane I occupied divided into two. I gently adjusted my steering wheel to the left, and in an unexpected turn of events, a dashboard indicator illuminated before my steering wheel rapidly veered to the right. This abrupt motion resulted in a collision with another vehicle, causing damage to both cars. Despite my attempts to avert the situation, my right thumb became trapped in the wheel, leading to a fracture. Shortly after the accident, the dashboard and multimedia system displayed multiple malfunctions: a VSC, TRAC, or Hill Start Assist Control system malfunction, a rear cross traffic alert malfunction, LTA malfunction, and a PKSB malfunction, all prompting a visit to the dealer. …
On Nov 05, at approximately 11:10pm, I was driving my RAV4 on Alafaya Trail, Orange County, Orlando. While approaching the traffic signal which had turned red, despite multiple attempts to engage the brakes, the vehicle continued moving, ultimately leading to the collision with the traffic turning left at the signal (coming from her right). The impact of the collision resulted in significant damage to the RAV4, and unfortunately, the airbags did not deploy as they should have. As a result, I hit my face on the steering wheel, and then hit the head on the left window when a second vehicle hit my RAV4 on the passenger side. The complete failure of airbag deployment has raised serious safety concerns for me. As of 28th November, I have been informed by our insurance company that the vehicle cannot be repaired and has been totaled. …
While accelerating ~6ft from a complete stop, a minor collision occurred affecting the front right headlight. The air-bags did not activate and the engine compartment was immediately on fire. Within ~1minute, the fire had spread to and completely engulfed the passenger compartment. The contents were immediately destroyed. The speed with which the fire spread through the vehicle was a significant risk to my life and the motorists around me. There were no warning lights on the dashboard prior to the incident, and the car had never before experienced an accident. Witnesses and firefighters estimated that any fire barrier between the engine and passenger compartments had failed, and that a fire of that severity from such a minor accident indicated some fault with the vehicle. The vehicle was an immediate total loss as inspected by our insurer.
While using Cruse control. It did not slow the vehicle. I could not turn it off. The brakes would not work. I ran thru an intersection against the light. Bounced over the median. I turned off the ignition, still coasted about 1/2 mile. Finally I jammed the gear shift lever into Park. Toyota has the vehicle for inspection and reading of the black box. THE CONSUMER STATED THE VEHICLE DID NOT HAVE ANY WARNING SIGNS OF THE FAILURE. WARNING MESSAGES DID DISPLAY DURING THE FAILURE, WHICH WERE "CRUISE CONTROL INOPERATIVE", "BRAKE FAILURE", AND "LANE DEPARTURE".
I was involved in an accident on the interstate traveling at about 80 mph and I hit a guard rail. I swerved, and then the lane assistance kicked in and made me lose control of the car completely, which is how I slammed into the guard rail. In that process, none of the airbags deployed and I had a passenger in the car.
New 2021Toyota Rave4 vehicle would take over steering and turn left or right from the center of the lane. This issue would consistently steer you to a road shoulder or into another lane. A less experienced driver would have crashed. The steering pull is so significant that one is unable to take a drink or turn on the radio without the possibility of an accident. The last incident steered me into the path of a Cement Truck nearly causing an accident. Had I not been extra cautious, an accident would have occurred. The "vehicle is operating as designed" and "some customers are overly sensitive to the safety features" was the conclusion of Vancouver WA Toyota Service and advised to return the vehicle when an incident reoccurs. I insisted the next incident could kill someone. …
I was in a bad car accident last Wednesday July 26, 2023 It was very scary and Bizarre; My car accelerated (started racing)and when I stepped on brake, it accelerated more. I saw a message flash up on my GPS screen but obviously couldn't read it as I was trying to stop my car. The Auto brakes didn't work, I crashed into a tree; air bags didn't deploy and I got this message ("CHECK ENGINE! A MALFUNCTION IN THE ELECTRONIC CONTROL OF THE ENGINE,THROTTLE, OR AUTOMATIC TRANSMISSION HAS BEEN DETECTED.CONTACT YOUR TOYOTA DEALER IN ORDER TO HAVE YOUR VEHICLE INSPECTED." (See attached). Luckily I was in an almost empty parking lot when this happened, if not i could have been killed or killed someone else. All the safety back ups failed. I took a picture of the message-will attach it to this report. …
On February 14, 2024, I was driving to pick up a friend who needed a ride to an appointment. I had the lane correction feature on while I was driving on the interstate. When I exited the interstate, I traveled on a two-lane road that becomes narrow as it travels along a downhill slope. This road has a steep ravine on the right side of the road caused by rainwater runoff. There are reflector signs cemented into the road along the steep drop off. Because there was no oncoming traffic, I crossed the center line avoiding getting too close to the edge. When I did so, the lane correction feature activated, pulling the car hard into the signs along the road. As a result, the entire right side of the car received extensive damage. I was fortunate not to have lost control of the vehicle and gone through the signs into the ditch. …
