Electrical System Jul 11, 2021 NHTSA owner report
Driving down the road and ALL the warning lights came on at the same time. They were flashing across the dash one at a time. We got a sway bar warning, an airbag warning, check engine light came on and then all of the sudden we lost power steering. It took all my husband's strength to control the vehicle when the power steering went out.
