“While driving in a city warnings on instrument panel came on: hybrid system failed , all wheel drive failed , take car to the dealer , and the car stopped. Had to have it towed to the dealer. Following day the dealer called me to say that everything in the car checked out ok and they couldn't duplicate the problem, I'm now very weary of taking the car on a trip because I don't know when it may quit again. The car just turned 10k miles.”
NHTSA complaint #11341428, filed 2020-07, 10,000 miles“The voice guidance system was inoperative. I bought it as a pre-certified 2019 Highlander from a Toyota dealer with 16k miles. At the time it was working the stopped working. After 3wks I found out that I have to push the start button 2x with the engine off to get it to work. Toyota has know about this for 2 years but no one includijng support told me about it! Will there be any recalls? It is too late to take it back! I will have to do this each time I use this feature.”
NHTSA complaint #11360974, filed 2020-09, 16,638 miles“The entire voice guidance system is inoperative on my one week old 2019 Highlander hybrid platinum. No audible voice or beeps with navigation assist, no phone assist,, no eyes-free assist, no driver announce to rear cabin voice, no entertainment system voice assist. This is a safety hazard eliminating hands free driving, and no navigation guidance. I was on unfamiliar roads in the dark of night, alone, unable to operate necessary equipment which proved to be unreliable. …”
NHTSA complaint #11242461, filed 2019-08, 200 miles“The computer/radio automatically shuts itself off and then reboots. It has done this too many times to count. It does this randomly and unexpectedly. It becomes dangerous because I live in a state where I am not allowed to hold a phone while driving, so when I don't have wireless phone capability it is very disruptive. It is also dangerous and inconvenient when it happens when I'm using navigation in an unfamiliar place, I am left stranded. There have been times when it continues to reboot continuously during my trip to or from someplace. …”
NHTSA complaint #11360580, filed 2020-09, 2,500 miles“We started the vehicle that is parked in front of our house at around 8am to get some groceries.

Pushed the break pad several times and the car won't stop. Finally moved the gear to p and it stopped and the engine turned off. I started the engine again and tried to reverse it, it won't reverse and only going forward. I called autonation Toyota of leesburg, they towed the vehicle. …”
