Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The first weeks seemed like everything was fine with the vehicle until we started feeling low levels of electrical shocks.

NHTSA complaint #11319901, filed 2020-04, 7,000 miles“The microphone has an issue and it is tied to the SOS call button in the car. I asked my dealership, they wanted to charge $200 to run a diagnostic scan, I contacted Toyota directly, they basically said the dealer can charge it if they want and reverse the charge if they find a problem under warranty. I originally thought the issue was with the Blue Tooth. I found this video on YouTube, his fix did work-my concern is, if I had needed Emergency help-the button would not have called anyone, disconnecting your car battery is NOT something I should I have to do to fix a 2019 vehicle. …”

The vehicle was taken to the local dealer who stated the failure was due to the remote start feature that was installed. The vehicle was not diagnosed or repaired. The contact stated that she noticed the mirrors were fractured. While driving at an undisclosed speed, several unknown safety features became inoperable. There was a burning odor detected inside the vehicle. …”
