Electrical System - filed 2024-11-12
My car sometimes cuts off while driving. Was on highway 301 running about 60 mph in the middle lane and just lost power no warning. No code no nothing. Sacred me, I truly feel that's a safety issue, for me and the cars behind me. It's bad not knowing when or where this will happen again.

Ignition lock issue. I’m guessing security light came on hard to start vehicle when switch doesn’t work. Almost left me stranded. Apparently this is common. I have kids and if I get stranded with them what am I supposed to do? Something needs to be done

Complaints are reports filed by owners with the National Highway Traffic Safety Administration.

Crash ratings are NHTSA's own 5-Star Safety Ratings results.
