general problems of the 2020 Toyota Highlander

The rear hatch door will not close or open and just sit there. And dings, you have to manually close it and open it most times and it never fully sucks up and latches fully and it doesnt notify you on the hood display of the car , so when we were driving down the road, we heard loud hissing and road noise coming from the rear and come to find out the rear hatch had never fully closed or latched itself fully. And it hangs up constantly.

Door locks do not lock or unlock with the car fob, now only the driver's side door does not unlock with the fob, you have to unlock from the passenger side.

1- most of the time my rear hatch will not close unless you use the inside button - cost 1,198. 10 to repair. 2- my car started making a whining noise on acceleration. Took it Toyota and they said that I need to replace my transmission that it has an internal failure. Of course my warranty was of no use b/c it stopped at 100,000 miles. At the time of the inspection I was at 104,000. To get a new transmission it will be 7,425. 60 (not including the labor). I really wish the dealership could have been honest about this year model transmissions failing. I would have passed on this car.

I was in a school line waiting for my children. I went to hit the gas to move and the car said “maintenance required” and then flashed other warning lights “low power steering fluid and engine light. ” then the car turned off and screens were flashing. I tried to restart the car but the steering column was locked and brake pedal was locked. I checked all fluids and they were full. I had someone jump the car and it turned back on. I figured maybe a bad battery. Had aaa come look at the car and all diagnostic testing was normal. Next day, car does it again in the middle of an intersection.
