Automatic Emergency Braking Problems of Toyota Avalon

On 11/27/25 around 11:30 am , I went to stop at a stop sign before approaching the main road. I went to stop at the stop sign and hit the brakes as I proceded to turn left on to the main road there was a car coming on the main road and I hit my brakes to stop from causing me to run into him when I hit the brakes to avoid hitting the other car , the brakes locked and would not stop the car. Causing the car to swerve and hit the car, went to the other side of the street , hit a pole , and damaged my left and right back and front of my car and hit the other car as well. It was not the first time that the brakes did this to me, however the first time that that happened thankfully I did not hit anyone on the on going road , but the brakes freed up and I continued driving. This timethe brakes froze and the car went out of control. I almost lost my life me and my husband who was a passenger in the car. The person whom I hit in the other car saw that I tried to stop and the car went out of control. The car would not stop. I am concerned because for a long time I have been telling the dealer when I go for service I complained about the knocking of the brakes when I press to stop. They said nothing is wrong and they never did anything about it. Now today I went to the dealer to complain about the accident I was in and wanted them to inspect the brakes. They wanted to charge me 199. 00 and I refused to have them diagnose the car because this appears to be problem with the car and nothing on my part. It may be a sensor issue or something. I felt that the car was being operated remotley in other words I had no control the car spinned out of control and the brake system did not work. I want to get rid of this car because I have had 4 accidents with this car since I purchased it in may of 2022. I am now afraid to drive the car after this incident. Please someone help me with this situation.

After starting to accelerate from a stop light ,the dashboard had a warning message that the accelerator and brake pedals were pressed simultaneously. The acceleration stopped and the car slowed automatically. After a few seconds the warning indicator went away and the car could accelerate. The cars behind my auto had to stop suddenly. At the time. I though that I might have hit both petals at the same time. When it happened again I opened an incident report with Toyota. Incident opened on 07-19-25 case # 250719000440. The Toyota rep told me it should be take to a Toyota dealer to diagmose any error codes. The next time the same problem occured I took it to my Toyota dealer and was told there were no error codes to indicate a problem. I have also taken the car to a local repair shop after the problem happened and was shown there were no stored errror codes. The dealer wants to have my auto for an extende time to reproduce the problem. If they need error codes to solve the issue but no error codes are recorded when the problem occurs what can they determine? I am hoping that there are other Toyota Avalon owners which might have had the same issue.

The manufacturer is no longer producing oem windshield that comply with the a das features which are now in operable because my windshield will not calibrate after replacement because there is not an oem windshield available. I have contacted Toyota. I have also searched everywhere in the states for an oem windshield Toyota has tried to calibrate the replacement which is aftermarket, as well as the auto glass installer to no avail. Toyota is no longer manufacturing the oem windshield which is needed for the safety features to function properly. The car should be recalled for a manufacturer defect.

While driving the pre-collision system (pcs) turns on unexpectedly, without any warning lights or sounds, and applies the brakes. This happens when I am driving in traffic with plenty of space between the car in front of me. I typically drive between 3-6 seconds behind the car in front of me to allow for at least 300 feet in space when driving at highway speeds. Despite leaving plenty of room for cars in front of me, on multiple occasions the car has started braking abruptly while going anywhere between 50, 40, 30, or 20 miles per hour. This can be verified for inspection upon request. Despite there being a recall for my specific year, make, and model car (2015 Toyota Avalon) for this exact issue my VIN number is not covered. Toyota is requiring me to pay out of pocket for them to 1) determine if its malfunctioning and 2) replace the system, which is a huge conflict of interest. Even though the driver's manual says that I can disable the pcs by clicking on the pcs on/off button within the driver's glovebox, there is no such button, only a blank button cover. Not having the ability to disable the pcs system, or worse, allowing it to continue braking while I'm driving is a serious hazard. The car can start braking while I am accelerating to merge onto expressway on-ramps, or while changing lanes at the same speed of traffic. The car can also unexpectedly brake while cars are traveling too close behind me. I want to know why my VIN was not included in the initial recall and why I now have to pay to have it looked at or repaired when its clearly malfunctioning and can't be turned off as the driver's manual says it can. I should not have to pay $175 an hour for several hours for a Toyota dealership to diagnosis it and then another $175 an hour for 2. 5 hours for them to install the fix and whatever the new component costs. I recently bought this car at 35,500 miles and the issue immediately started occurring just as the warranty expired at 36,000 miles.

Multiple warning lights suddenly appeared on the dash while stopped at a traffic signal. (photo attached) note: the photo does not show the red "pcs" light which was flashing. I was able to get off the road safely although the brakes did not feel normal. Had the car towed to capitol Toyota in san jose the following morning for repair. They diagnosed the problem as a failure in the master cylinder booster unit and replaced it. Note: the attached invoice misstates the issue as "check engine light" which is incorrect.

I represent the family of a fatally injured rollaway victim. It is on their behalf I am reporting the circumstances of this incident and to strongly urge that NHTSA update the rollaway requirements specified in federal motor vehicle safety standard 114. On August 22, 2020, it is believed that while attempting to retrieve the key fob, the driver inadvertently bumped the gear selector forward into neutral, releasing the torque to the wheels that had kept it stationary on their sloped driveway. (unlike shifting out of the park position, which requires application of the brake pedal and depressing the lock button on the shift selector, the shift selector can be moved from drive forward into the neutral position, without a secondary interlocking action. ) the drivers wife, who was behind the vehicle. Was pinned by the car and dragged under to her death. The position of the transmission gear selector was not documented by any witnesses or first responders when the vehicle eventually came to rest on the opposite side of the road, not is it documented in the extensive data stored within the vehicle. However, the data retrieved from the subject vehicle during a subsequent inspection revealed that the vehicle control history (vch) included a field for “driver exited vehicle when shift position wasn’t p” which showed that at the time of the incident that is exactly what happened. Finally, there is ample evidence to support the need for an upgrade of the rollaway provisions within fmvss 114 – as the facts above show. It’s not enough for a safety agency to simply allow manufacturers to do so voluntarily. . Instead, the Toyota was content to collect the data and blame the driver for an event that it clearly knows occurs and has extensive information about, but fails to prevent. The public needs to rely on NHTSA to promulgate updated regulations that meet the safety needs presented to drivers of modern vehicles.

The pre-collision braking system does not appear to work. Several times when cars in front of us have slammed on their brakes, the pre-collision braking system does not respond. We own a 2016 prius with the same feature and it always responds � flashing a warning and applying the brakes. We complained to the dealership multiple times, and they said the system in our car performs a check every time we turn on the car and since it does not indicate a fault, to their knowledge the system is working fine. They said there are no other tests for them to perform. I've adjusted the system to the most sensitive mode (active when vehicle in front of us is further away), but this has had no effect. Also, the adaptive cruise control which uses the same radar system as the pre-collision braking works fine. There definitely is something wrong with the pre-collision braking, and I am concerned that this safety feature will not save us from a collision. The only way someone would be aware that the system isn't working is to experience a near collision. I believe the pre-collision braking system could be tested without damaging our car by placing a large stationary inflatable object in front of our moving car. I would be glad to provide our car for you to perform such a test or another test that you may have developed. This may be a problem with many other Toyota Avalons and other cars.
