I have a carbon monoxide leak going on since I bought this vehicle. I have been complaining about noises I have been hearing from the drive train and got a diagnosis from the same dealer with well over 1k worth of work. This has caused me a lot of lost money since I have been from dr to dr and back and forth with the dealership and now I tested for carbon monoxide and it’s leaking into my vehicle the dealer keeps telling me it’s fine it need a tune up or evap system clean. I am not able to drive this car safely and I have permanent brain damages from the carbon monoxide gas

The High voltage floor underwire harness and rear traction motor cable corroded. This caused many if the vehicles sensors to fail completely including the tire pressure monitor system, adaptive cruise, collision avoidance, and more. Toyota is aware of this problem and attempted to do a silent warranty extension. This is a safety hazard and all of the known vehicles affected should be recalled!

Nov 29, 2023 Crash

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. Our insurance company GEICO has been requested to hold on to the vehicle for necessary investigations.

I was on highway 41 going around 40mph when my car out of nowhere slammed on the breaks ( the pre collision censor ) I believe is what caused it. About 10 mins prior to the incident when I was backing out of the gas station it braked (abruptly with noise) even though nothing was in the way or approaching my vehicle. I would say that I was stuck in the car for about 5 mins before I could get it to start driving again. The electrical flashed and shut off right when the car braked. I did have my two dogs in the backseat and thankfully no one was harmed.

Aug 13, 2023 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. Upon contacting Toyota, they offered no assistance, asserting that the incident occurred at an approximate speed of 22 miles per hour due to data from the EDR. However, this contradicted the facts as my vehicle was stationary at a red light. The explanations provided by Toyota's representative, Alexis Turner, appeared inconsistent with the circumstances.

Aug 1, 2023 Crash

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. I was taken to Huntington Hospital ER and had a cat scan to make Sure my sternum and ribs aren’t broken-showed Soft tissue abdominal swelling and bruised sternum and ribs from my seat belt. Pain to chest, ribs an right side. I believe my car is totaled Just had it inspected and serviced a few weeks ago at the Toyota dealership where I purchased it and it only has 10,000 miles on it! I am Fighting with insurance company to make sure the car's computer is interrogated before they do anything else.-The insurance company was pressuring me to release the car to Copart without this being done and I refused. My car was towed to and remains at Combined Auto Collision 4035 Jericho Tpk, East Northport, NY. This incident could have resulted in a catastrophic outcome and loss of life. Aa investigation needs to be taken to insure this does not happen to anyone else. Thank you for your kind assistance The consumer stated that the dealer identified the problem being that the water drainage pillars short out the electrical system.

Driving with cruise control on, on a 2 lane road with a left turn lane. Approx 40MPH. Vehicle ahead of me by 4-5 car lengths got into left lane. When I has about 10 feet from him my brakes automatically slammed on, he was in his lane, I was in my lane. This has happened 4-5 times since I've had the veh. I now stay aware that this might happen and stay ready to cancel the cruise. This could be very dangerous if someone was right behind me. Dealer test drove and ran scan no problem found. Which as expected, if it doesn't happen when they test drive there's not a lot they can do. I understand this.

While traveling on highway with adaptive cruise control engaged and maximum following distance selected, adaptive cruise control applies excessive braking force than necessary when vehicle in front exits highway. Safety concern because following vehicles must abruptly apply brakes. Internet search reveals numerous, similar complaints. We were almost rear-ended on the highway. This feature is great, but needs attention for safety reasons.

Apr 5, 2023 Crash Fire

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.

Mar 27, 2023 Crash

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. Post-note for 3/27/2023 - we picked up from the collision repair and the car and the collision control was still flashing in error - and will be taken back to Toyota dealer on 3/28/2023 to have them read the computer. Other similar incidents have been reported for 2021 RAV-4 - and a similar recall went out for Toyota Prius we found after the crash.

Does not maintain cruse control speed that I set when traffic becomes heavier around the car for example….cruise control stops working and car slows down as vehicles are passing my car, or are driving in front of me or in back of me. It does not like traffic near by. If there’s no traffic it works and maintains the set speed.

Aug 11, 2021 Crash

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".
