2022 Toyota Highlander Electrical system Problems

“When turning on the heated steering wheel and about 5-10 minutes, it seems there is smoke coming from the steering wheel leather and it’s very hot that almost burnt my hand and forced me to take my left hand off. I immediately turned the heated steering wheel and stopped. There is a burning spot left on the steering wheel also. The heating option still can be enabled and the same situation repeats (like no fuse was broken)”

“While having the eco system on, with the active system present by firmly pressing the brake hard at a stoplight, the light turned green. while taking my foot off the brake and the engine turning back on, attempting to accelerate the transmission would not allow me to get through the intersection turning left.

I was finally able to shut off the engine and luckily for me the airbag system didn’t deploy.”

“I am writing to formally express my dissatisfaction regarding a failure of the power liftgate on my Toyota Highlander and the fact that I was required to pay out of pocket to have it repaired.

When the liftgate stopped functioning properly, I was faced with an unexpected and costly repair expense. I believe Toyota should take responsibility for this failure, particularly given the nature of the component and the circumstances surrounding the repair. …”

“The only door that will lock or unlock using the fab key or the master lock button on the drivers armrest is the drivers side rear door. My vehicle is not able to be locked unless I do it manually and can not be unlocked unless i use the rear drivers side door. This has been reproduced by the dealership.
