2021 Toyota RAV4 driver assistance problems

Filed Sep 25, 2026 · Driver assistance · SC · crash

While changing lanes in my 2021 Toyota RAV4 with my turn signal activated, the Lane Departure Alert / Lane Tracing Assist system applied an unexpected steering input that pulled my vehicle directly into a Jersey barrier, resulting in physical contact with the barrier. I was intentionally and safely moving into the adjacent lane when the system intervened abruptly and steered my vehicle toward the barrier. My speed was approximately 55 - 60 mph. The weather was rainy off and on but not raining at the time. The road surface was damp. The lane markings were clear and no dashboard warnings appeared prior to the steering event. I had my blinker on and was actively changing lanes. The lane‑assist system should not have intervened during a deliberate lane change, yet it applied a strong steering correction that overpowered my input. I attempted to counter‑steer, but the system’s force caused my vehicle to strike the barrier. My vehicle made contact with the Jersey barrier, causing damage to the driver’s side of my vehicle. The unexpected steering input created a sudden loss of control and a dangerous situation that could have resulted in a more severe crash. I am aware of other 2021 RAV4 owners reporting similar unintended steering behavior with lane‑assist systems, including steering toward barriers or roadside objects. This appears to be a recurring safety defect involving the vehicle’s lane‑keeping functionality. A lane‑assist system overriding a driver‑initiated lane change, especially with the turn signal activated, and steering the vehicle into a fixed object presents a serious risk of injury or death.

My Toyota hybrid AWD vehicle experienced corrosion of the rear traction motor cable, which Toyota has acknowledged in Service Campaign 25TD01. This corrosion affects the electrical connection to the rear drive motor and can result in loss of AWD propulsion capability. Loss of rear-wheel propulsion significantly reduces traction and stability, particularly in snow, ice, and wet conditions. Drivers may believe the vehicle still has AWD capability when in fact the rear drive system is compromised. In addition, the vehicle’s adaptive cruise control system repeatedly turned off unexpectedly while driving and displayed “unavailable” warnings. These malfunctions occurred alongside the electrical issues related to the rear traction motor cable corrosion, suggesting the defect may affect multiple vehicle systems. Toyota has acknowledged this defect through Service Campaign 25TD01 but has not issued a safety recall. Given the potential for loss of propulsion and malfunction of driver-assistance systems, this issue should be investigated as a safety defect.

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). We spoke to the auto body shop who will be repairing the car and they told us that the brakes currently seem to work. A online search revealed that this problem as been reported / discussed by others in the past. We expect to have the car repaired and returned to us in the next week but are very concerned with driving it as another accident could be fatal.

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.

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!

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. My first reaction was to think that I had lost a wheel or had a tire blow out for the car to have jerked so hard to the right. When I stopped, I saw that this was not the case. I have since read that there have been many instances where the auto lane correction has caused other accidents like mine, some of which have been more severe. It is unfortunate that I have the inconvenience of getting the damages fixed and an accident being reflected in my insurance as a result. However, I feel fortunate that I was driving the car and not one of my children who may have lost control. I am glad the signs were securely installed to keep me from rolling into the ditch. I feel most blessed that nobody was injured. What if I had swerved to avoid a person walking on the road instead of the signs posted there? There was not a police report taken on this accident. It was reported to the dealer and insurance company who referred me to Caliber Collision for repairs where it is currently. There were no warning lights prior to the incident.

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.
