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

While driving the vehicle on an uphill stretch of highway with cruise control set at approximately 65 mph, the vehicle suddenly slowed down without warning. A distinct clunk was heard at the same moment. The cruise control system attempted to restore speed, and the engine became noticeably louder, but the vehicle struggled to return to the set speed. The driver tapped the brake to disengage cruise control and manually pressed the accelerator to resume normal speed. The trip was completed without additional events. After parking, the check engine light illuminated and the cruise control system became disabled on all subsequent drives. No warning indicators were present at the time of the initial failure, and there were no vehicles ahead that would have triggered the collision-avoidance system. Two days later, the vehicle became an intermittent no-start and eventually failed to start entirely. The vehicle was towed to a dealership for inspection. Technicians confirmed an electrical malfunction and reported that the multiplex ECU was likely experiencing an internal short. A parasitic draw test showed an abnormally high current draw of approximately 113 mA, which disappeared when the dome-light fuse and later the multiplex ECU were disconnected. The failure is intermittent and appears to involve an internal electrical short within the multiplex ECU. The sudden loss of cruise control function, abrupt deceleration, and subsequent intermittent electrical behavior created a safety risk, as the electrical malfunction occurred without warning while the vehicle was in motion. The issue was confirmed by a dealership service department.

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.

I have a 2017 RAV4 Hybrid XLE that I bought brand New. I have done all schedule maintenance on it. I was driving to an appointment on 15 November 2023 and the vehicle all the sudden jerked violently side to side throwing me off the road. I brought the car to the shop thinking an alignment or something. My whole rear subframe was cracked, and by the driver side rear wheel bolt it was broke straight through where the tow bar connects to the subframe. The mechanic said it was from rust from living in the Northeast, and the salt from the road during winter months. The Mechanic said Even though I took care of the vehicle this was going to happen anyways due to the subframe suspension parts that Toyota puts in the RAV4. Being flung into a ditch coming off a highway is a dangerous situation, and could of cost me my life because Toyota wants to save money and put in parts knowing that the rust problem will and could occur. I did my research, and found out this has been going on since 2007 and there have been recalls on models all the way up to 2012. If this is a known thing then why is Toyota being allowed to still make a weak subframe. Does someone have to die for this to be stoped. I’m am asking for a recall on all models of 2017 Rav4 hybrids and on to fix this problem. I am lucky to escape with minor injures, but maybe the next person isn’t. Something has to be done.
