If I could give zero stars I would.
I recommend avoiding these folks at all costs.
Got a reasonable trade and deal on a new 2015 Silverado HD truck which I ordered in early 2014. That was then end of the good.
Last visit they damaged my truck, said they test drove my issues (hmmm 0.2 miles added on the Odometer), and fixed a recall. The recall is still active on my truck with GM, so I guess they didn't damage the truck, fix the recall or test drive the issues.
Couldn't even get an oil change and tire rotation correct, not even an apology or offer of a free one for their screw up.
Offered solutions to make me a happy customer and refused every one of them.
Was told if I didn't like it, go fix it myself. Yeah, that's really good customer service/warrenty on a very expensive truck.
They know how to play the game
Many issues under warranty with the truck not repaired, they blamed GM not approving repairs,GM says dealer says nothing wrong with truck. GM says they are not responsible for dealer actions since dealer is private. Get the game played?
I asked to speak with the owners or even the GM, was told personally by the GM to let him know if I ever ad problems. He refused to answer my calls.
I was told they don't ever want to see me again. Great customer service.
Never Ever Trust Bertera or General Motors Again.
