Stay far away from these sheisters! I would take a look at Ofallon GMC or Dave Sinclair first, and if you 100% have to purchase here do not buy a "pro pack" or extended warranty, its lik I would take a look at Ofallon GMC or Dave Sinclair first, and if you 100% have to purchase here do not buy a "pro pack" or extended warranty, its like throwing money away, they will not honor the claims More

I purchased a brand-new car from Suntrup Buick GMC on May 6 2025, and 2 weeks later the engine light comes on. The same engine-light issue has persisted for three months. I may have driven my car for two wee 6 2025, and 2 weeks later the engine light comes on. The same engine-light issue has persisted for three months. I may have driven my car for two weeks out of the three months. I’ve brought it in for service three times due to the recurring problem. No follow up on what the issue is other than the censure. The dealership claims they called me on July 9, but I never received any messages. I had been trying to work directly with the GM to get this matter resolved, but keeps getting the run around. Although the service desk has called me before, they gave me some phone number that wasn't mine, communication has been inconsistent. Today, I spoke with Dave Brewer in the Service Department. He was unhelpful, argumentative, and showed no compassion. When I explained to him that I didn't want the vehicle back, without any resolution to my concerns, he insisted I call GM and demanded the return of the loaner car. I reiterated that I had been attempting to follow up without any response. I asked if he could contact GM on my behalf, but he refused, claiming GM is responsible because they make the vehicle. When I pointed out that I purchased the vehicle from the dealership, he said... my vehicle was ready and if I didn't return the loaner today or tomorrow he threatened to file a stolen car report---then abruptly hung up. The customer service has been absolutely unacceptable. Roz M More
