Starting problems.
Rattles.
Trim came loose.
Wheel bearings.
We traded our trouble prone Equinox in for the Impala. We made a mistake. We should have traded the Equinox in for a different brand.
The car does not start some times. Dealer can find nothing wrong.
Car rattles but not when at the dealer.
Interior trim has come loose a few times.
Front wheels made a Knock/Pop when turning. New wheel bearings.
Sounds like you have a bad Chevy dealer. Sorry. The trim might be loose from the techs taking it off to check out your electrical issues... just a thought.
