There are 2 owner-reported driver assist & adas complaints for the 2017 Toyota RAV4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
PCS brake has enormously engaged twice. 1. small branch fell off tree on a dirt road. brakes engaged and should not have and almost caused vehicle to slide off a 1000 foot cliff. 2. auto braked with my dog was in car and broke dogs' leg and cost a 2,000 dollar vet bill. brakes where not needed i could have easily just did a slight steering adjustment to avoid collusion. the braking prevented that and almost was also almost rearended overall, the autobrake can be disabled with a lot of work on various menus. but comes on when the car is restarted. I do this every time i restart the car. I suspect a glitch or a low voltage caused it to come back on. Also trying to always remember to do it is difficult to do. I consider this auto brake to be a huge safety risk and could cause loss of life. I am so scared by this and afraid to dive the car now. may have to take a total loss on the car I just bought. Toyota dealers said they cannot reprogram the car to prevent this serious safety risk
My 2017 Toyota RAV4 XLE is experiencing unsafe behavior with the Adaptive Cruise Control (ACC). When driving around modest or slight turns, the ACC frequently loses tracking of the vehicle ahead and suddenly accelerates, then harshly brakes once it reacquires the vehicle. This creates a jerking motion and significantly reduces my confidence in the system. On one occasion while traveling approximately 45 miles per hour on a slight curve, the ACC began rapidly accelerating toward the vehicle in front of me as if no vehicle was there, forcing me to perform an emergency manual takeover and disengage the ACC to avoid a potential rear end collision. This issue is repeatable and appears to be related to how the ACC detects vehicles ahead while cornering. I am requesting that this behavior be investigated as a potential safety defect.
