Reviewed by bookkeepermauriceOctober 20, 2025

On July 29, 2025, I purchased a 2021 Chevy Suburban from O'Meara GMC for almost $40,000.00. Upon pickup, I discovered the middle row seat adjustment handles were in the glove box, and the seat would not return upright. Sales and service staff attempted repairs but failed, and the vehicle was kept overnight. I was told parts needed to be ordered and that I would not be financially responsible. I was later informed I couldn't drop off the vehicle for repair until August 7, which I did. I drove my new car with the broken seat until 8/7. During the time my vehicle was being repaired, I was given a loaner vehicle with recurring tire pressure issues, including a flat tire by August 13. It was unsafe to drive. On August 14, I was given an electric loaner vehicle, which was highly inconvenient. Charging took over an hour for only 80 miles of range, causing me to miss work and personal obligations. On August 25, the dealership charger was unavailable when I was assured it would be ready for charging. I picked up my Suburban on August 26 after three calls letting me know if was ready. The seat was repaired, but the plastic cover between the middle seats was not properly closed. It is wide open with grease exposed. I reported this on August 29 and received no response. Additional concerns include a worn tire noted in the inspection that was not replaced until I requested it, and a misrepresented heads-up display feature that my model does not include. I had been without my vehicle for nearly a month immediately after purchase, I was expected to rely on unsafe or inconvenient loaners, and experienced very poor communication. I am requesting immediate resolution of remaining issues, a clear timeline for any further repairs, and confirmation that my vehicle will be restored to full working condition. GMC O'Meara needs to take accountability and compensate me in some way for the hassles I have been experiencing. Steven lied on the BBB response and my seat is still not fixed to 100%. These people are grimy.

Run away as fast as you can from this slimy dealership.

Run away as fast as you can from this slimy dealership. Had a deal negotiated to the penny on a '26 Sierra EV AT4 with one of the managers including my trade-in. This was on a Thursday morning. By late afternoon I became concerned that I hadn't received the written deal via email as promised. The manager was gone so I spoke with the salesman I initially contacted. He told me he would have to speak with the GM to see if they could hold the vehicle. I told him I had a done deal and was ready to give a deposit on my credit card. He wouldn't take my deposit and said he would speak with the GM in the morning. The following morning I was told the GM had agreed to hold the car the following Monday if it didn't sell over the weekend. I told him that's not how I do business and would purchase elsewhere. Monday I receive a text from the Salesman that it didn't sell and was still available. Now way I'll ever do business with such a sleazy dealership. I purchased from a different Denver dealer that treated me like royalty. Wasn't able to work my trade into the deal but I'm confident I'll come out ahead by selling it myself. Plus I got the color I wanted.
