general problems of the 2015 Toyota Highlander

I have noticed speed issues or high idling with this vehicle for a while. I committed a rear end collision with a vehicle on July 4, 2025, at approximately 2pm. My car rear ended his truck while it was stopped behind another vehicle. My vehicle sustained total damage to the front end. I was ticketed for not reducing speed to prevent a accident. The only warning light was that it need maintenance, which comes on prior to an oil change. My safety was put at risk because the car is idled too fast for the type of driving I do, which is small town and rural road driving. Due to the speed of this vehicle during normal driving, it's difficult to stop quickly to avoid an accident. If it was rainy and slippery, the situation could have been much worse.

On [xxx] my vehicle suffered an unintended acceleration on a very busy highway of the dominican republic, reaching a speed of 100 mph. I was able to drive the car into the bushes of the highway service road hitting all king of obstacles such as trees, wall, advertising signs and safety barriers. The car damages resulted in a total loss. My life and my family life were in extremely dangerous situation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving to take my son to work. Check engine light came on said check and system. Hard shifting put in manual drive and made it to destination.

When driving my Highlander the following error messages appeared, error keeping the start button pressed will cause an emergency stop. I dismissed this. Then it popped up a message that car cannot drive while brake and accelerator are pressed simultaneously. I lost ability to accelerate so tried to pull of busy road, pressing the brake pedal restored acceleration. Then when I stopped in traffic or at lights the car shut itself down and had to be restarted. These error messages kept coming on while I drove to the dealer. I switched off the car at the shop and it wouldnt repeat the problem, no codes have been recorded by the vehicles computer because the check engine light never came on. Toyota and the dealership want to wait until it happens again. Since it happened before, also while it was driving I am uncomfortable as it is a safety concern. I don't want it to happen on a busy highway. I believe the intelligent power module of the car is shorting out and causing the car to go into failsafe mode and shut down creating hazardous driving conditions.
