What owners wrote

“When stopped at a stop light and using the auto off feature the Highlander stalls. The automatic shutoff repeatedly keeps draining the battery unless I manually turn the automatic shutoff feature off so it does not shut off when the vehicle is stopped. This has continued to happen over the last year and a half.”

“Car shut down multiple times while driving. Car lost steering and all power then somehow came back to life without me touching anything. It’s as if the car decides to shut down when All Wheel Drive kicks in. First the entertainment system shuts down and then the entire car shuts down.”

Should you keep driving it?

This page can't tell you that. 0 of 48 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
