Adaptive Cruise Control problems of the 2018 Toyota Highlander

On a trip to nc on June 27 2024, then on to hilton head SC on 6/29, multiple system warning lights suddenly appeared on the dash including abs, lane departure warning, bsm, notifying me that those safety features were not available on the vehicle. Sometimes the the lights would disappear, especially if the vehicle was stopped and the engine was turned off at a rest area. Because the check engine light was not lit, I continued to our nc destination. We continued our trip on 6/29 to hilton head, and the lights continued to appear, sometimes staying on for an hour or more. I called my binghamton NY Toyota dealer who advised me to have the problem looked. I was able to have the car seen at savannah Toyota (GA) where they diagnosed the problem as an issue with rust and debris on the left front speed sensor. I had the recommended service performed. The service report says that I requested replacing the abs sensor, which is totally false, because I had no idea what the problem was, I just wanted it fixed. The part was ordered and replaced the next morning. All the lights were back on the next day when I drove back from savannah to hilton head. I did not have time to go back to the dealer, but did notify the service manager of the situation. I drove the vehicle back to NY with the warning lights on (most of the time). I now have a service appt with my local dealer on 7/9/24 to determine the next step.

About6 months ago I started getting the messege "breaking power low" when I try to start my vehicle. So I took it to star Toyota service paid $175 to diagnose the problem. The found dtc 1241 and told me to change the qhole skid control unit. Eventhough on the paper it said skid control ecu battery. So I took it to another dealer named penn Toyota and they found the same code but they said the voltage is coming low because I may leave my ignition on before I start my vehicle. That sounds funny because I do not do this and on top if I do this my battery would be dead. As of right now I spoke with Toyota and since my extended warrenty has finished so they offered my 25% coupon if I fixe the problem. Now I do not know what is the problem and which dealer to trust. The reason I am reporting to "NHTSA" is because if I die because of this problem with my car which is still undiagnosed so at least they can find out the same reason so there will be no more death after me. Again the messege comes on the crean is " breaking power low. Stop in a safe place ".
