2018 Toyota Highlander Complaints

UA80F Transmission failure at 100k miles for the 2018 Toyota highlander SE. No warning lights, engine noise (high pitched whine while driving). Took to the dealer and was told the transmission needed to be replaced.

First symptom I noticed was the car smell while it was running. I used a device to see what codes of any would pop up on a scan. It came up with codes tying into the fuel system. I then went to go fill up on gas couple days later and when going to start it back up it wouldn’t start. When it did start it would say engine losing power or steering losing power and then just shut off. I then looked up what that usually means and it made me look towards the alternator. I was told by a mechanic an easy way to see if your alternator was good was to start car and while running disconnect the negative on battery and if it stays running the alternator was still good. So I did that and it stayed running. I then looked up recalls for my vehicle and seen everything it was describing for the fuel system seemed to be happening. I am now filling this form out to get my vehicle looked at and fixed. I have a wife and 2 young daughters that we drive to school. It is not safe to be driving and hoping that...

The contact owned a 2018 Toyota Highlander. The contact stated that while driving at 35 MPH, occupied with her children in the rear passenger seats, the contact was attempting to merge onto the intersection, and a state trooper failed to yield at 55-60 MPH vehicle crashed into the front driver's side of the vehicle, causing the whole front end of the vehicle to detach from the vehicle.

The contact stated that she and her children sustained injuries, however under direct legal advice, she cannot disclose this information. Medical attention was required. The contact stated that a police report was filed. The contact mentioned the vehicle was towed to a collision center where it was declared destroyed. The manufacturer was not notified of the failure.

Currently at 113k miles. VIN # is not on the recall or extended warranty list for transmission issues, shift lag has been noticed way before 100k miles. vehicle is making squealing noise on drive, and when gas petal is press. Since no recall, but per research, I may have a faulty transmission that is left out of the Customer support program zjc, t-SB-0160-18.

The UA80 8-speed automatic transmission failed catastrophically without any prior warning symptoms while driving on the highway. During normal acceleration to pass another vehicle, the engine revved to 5,000 RPM as the transmission slipped, then dropped to 3,000 RPM coasting. After exiting the highway approximately one mile later and coming to a stop at a red light, the transmission would no longer engage in any forward gear. The engine revs freely when placed in drive and the accelerator is pressed. Reverse still functions. The vehicle had to be towed from the roadside. This created a serious safety hazard. The driver was stranded on the side of a busy road and lost all forward propulsion without warning while operating at highway speed. The failure occurred suddenly with zero prior symptoms. The vehicle was operating normally around town earlier the same day. The driver had no advance warning of any kind, no warning lights, no unusual noises, no shifting irregularities, before the ca...
