The contact stated that the brake warning light illuminated, and the brake independently activated. The vehicle was taken to a specialty brake shop, where it was diagnosed that the brake actuator had failed, causing the ABS system to activate independently. The vehicle was repaired. On the drive back to the residence, the failure recurred. The vehicle was taken to an independent mechanic where it was diagnosed with brake master cylinder failure. The brake booster, gasket, and brake actuator were replaced. The contact stated that two weeks later, the failure reoccurred. The vehicle was taken to the dealer where it was diagnosed and DTC: C1441 and C1431 were retrieved, indicating an issue with the ABS system lateral acceleration sensor circuit or the brake booster. The dealer became aware that the front bumper bracket had paint on the part that did not allow for the vehicle to brake correctly. The brake pedal support assembly with sensor was replaced, and the paint was removed. The vehicle was repaired. The contact related the failure to the federal safety agency Campaign Number: 15V728000 (FORWARD COLLISION AVOIDANCE). The manufacturer was made aware of the failure. The failure mileage was 83,829.

False forward collision warnings by model year
What owners say
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.
