Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Electrical gremlins since the first day. Touchscreen went on and off, phone didn't charge, door handles don't work, garage door opener forgot settings, presets on dash would blink out of memory. Ultimately the car didn't even start. But for all of these problems, sometimes they would work, sometimes they wouldn't. Ultimately got the yellow wrench of death. Brought it in repeatedly and they could never reproduce the problem, until the day it wouldn't start at all and the wrench was on the dash. Finally diagnosed open seams on the back hinges to the hatch. Seamseal was missing on both hinges. …”
