Adaptive Cruise Control problems of the 2021 Toyota RAV4

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!.

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.

Cruise control suddenly quit working, alarms for hybrid system malfunction, cruise control malfunction. This is a known issue for Toyota, high voltage leaking out because of a corroded ground. This repair is going to cost around $7,000 out of pocket. . My car is 3 years old.

While traveling on highway with adaptive cruise control engaged and maximum following distance selected, adaptive cruise control applies excessive braking force than necessary when vehicle in front exits highway. Safety concern because following vehicles must abruptly apply brakes. Internet search reveals numerous, similar complaints. We were almost rear-ended on the highway. This feature is great, but needs attention for safety reasons.

1. For two different occasions the high beams wouldn't turn on at night on a dark road and rainy day. Took the vehicle to Toyota but mechanic reported that he couldn't reproduce event. I had to drive very slowly with normal lights as I could. 2. For two different occasions the vehicle wouldn't start I almost had the vehicle towed but using the Toyota app and the key fob was able to remote start and then start the vehicle. I can't imagine what would have happened if the car turned off in the middle of an intersection and wouldn't turn on. 3. The adaptive cruise control has a glitch that I have told Toyota. If you're going over 30 mph and the vehicle in front of you has been in a complete stop for a while, the car may not stop you have to manually stop or crash. This could be extremely dangerous.

While using cruse control. It did not slow the vehicle. I could not turn it off. The brakes would not work. I ran thru an intersection against the light. Bounced over the median. I turned off the ignition, still coasted about 1/2 mile. Finally I jamed the gear shift lever into park. Toyota has the vehicle for inspection and reading of the black box.

Does not maintain cruse control speed that I set when traffic becomes heavier around the car for example…. Cruise control stops working and car slows down as vehicles are passing my car, or are driving in front of me or in back of me. It does not like traffic near by. If there’s no traffic it works and maintains the set speed.
