I took my 2026 truck in to have a bed cover installed

Reviewed by donprater2021November 04, 2025

I took my 2026 truck in to have a bed cover installed that I had bought from them online. I figured that since they were only charging $100.00 to install it that it wouldn't take to long. After 3 hours I watched them struggling with it. They said that no instructions were with the cover. Another hour later they had it installed and asked me if I had a key to lock it. When told I didn't they looked at the bag that they had put in the front seat. The key was in the bag along with the instruction book. They also said that there was a wiring harness in the bag. They were drain tubes that they failed to install. I only hope that I have no problems with this truck, because I don't want to come back to this dealership ever again.

Post-sale follow-up was terrible.

Reviewed by Daniel F from St. Louis, MONovember 01, 2025

Post-sale follow-up was terrible. It took 6 weeks to get the paperwork for titling the vehicle. I called the salesman twice to follow-up on it. They forgot to send the vehicle and emissions inspection with the paperwork. I called to ask about the inspection and they said they could email the inspection to me... but, oops, the inspection had expired. I was told I could make an appointment to have another done. I said it wasn't convenient to go to Trenary - they are 35 minutes from my house. They said I could go to any dealer for an inspection. I asked, "Any Chevy dealer?" "No any dealer," was the response. "But will I have to pay for it?" I asked. They responded, "Yeah." Complete xx and terrible customer service.

Took my Camaro in for a simple LOF, and the service

Reviewed by Line Up & WaitOctober 09, 2025

Took my Camaro in for a simple LOF, and the service advisor Chris was rude from the start. He tried to upsell me on an engine induction service even though the car only has about 9,300 miles. Then he tried to pitch a “red dot” service he could not even explain. He just threw a price at me and wanted me to say yes. I have a maintenance plan that was sold by the dealership, but he said they do not handle that and that I would need to pay up front and get reimbursed later. It is funny how a dealership can sell you the plan but not support it. They did not top off the washer fluid, did not reset the oil life monitor, and overall it felt like they just wanted to get me in and out without doing the basics right. Poor communication, poor attitude, and poor attention to detail. Definitely not the kind of service I expected from a Chevrolet dealership.
