Adaptive Cruise Control Problems of Toyota Highlander

Subject: transmission issue – 2021 Toyota Highlander dear NHTSA, I am reporting a serious transmission issue with my 2021 Toyota Highlander (82,000 miles). I recently took it to the dealership for an unusual noise, and they diagnosed a transmission failure, quoting over $9,000 for replacement and service. After researching, I discovered Toyota has known about transmission issues in the 2021 Highlander since at least 2021. I have always serviced my vehicle at the same dealership, yet they never informed me of this known defect. Instead, they waited until my warranty expired to disclose the issue, despite my repeated maintenance visits where I reported the noise. I also found a 2021 Toyota document acknowledging transmission problems in this model, and many other owners have reported the same issue. It seems dealerships avoided addressing this until warranties expired, leaving owners with massive repair costs. This raises serious concerns about Toyota’s handling of known defects. I urge the NHTSA to investigate and take action to protect consumers from unfair repair costs and potential safety risks.

There is an open recall which has not been addressed in a timely manner. The below has been open since oct 26, 2023. I have been advised that I would be notified when a remedy was available but it's been ten months with no solution. My front bumper detached while I was on the interstate causing damage to the front end of my vehicle. The subject vehicles are equipped with a resin front lower bumper cover assembly, connected with mounting tabs. If there is minor impact to the lower front bumper cover assembly that causes the mounting tabs to detach from the vehicle during normal operation, one or more parts of this assembly could detach, which could become a road hazard, increasing the risk of a crash or injury for other road users.

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 ".

I was using the adaptive cruise control on I-68 in western maryland. I was in the fast lane (on the far left of three uphill lanes). A dump truck was in the center lane going well below the speed limit. The road curved to the left at the point where I got up to the dump truck. There was no one in front of me in my outside lane. My car sensed the presence and speed of the dump truck and slowed me abruptly. There was considerable risk to me and to the driver of a white pick-up truck that was behind me, and who was also driving at passing speed. We were both going approximately 75 mph when my car slowed--a slowing that does not display brake lights. The cruise control has not been inspected. It is the default setting on ignition. I routinely disable it, opting for regular cruise, each time I use it, but the potential is always there for me and for other owners. If there was any sort of warning (I don't remember) it would have been inadequate to prevent an accident. The alertness of the pick-up truck driver saved us both a collision.
