Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My truck started to activate the brakes in the middle of the 3 lane 680 freeway, doors started to lock and unlock, navigation went dark, multiple different displays on dashboard, number of lights from the air conditioner unit, came on. Acceleration or brakes would not respond, we were unable to drive off the freeway. It was a scary moment, we were lucky that no big rig was following us, or it would had runs us over, and probably killed us.”
