What Others Say

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 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

Vivek was amazing! He helped me sell my junk car to use towards my down payment and got me a reasonable deal to lease a brand new buick envista in my budget!

very good very very very very very very very very very very very very very good

brought car in, told them what was wrong, they did evaluation on what I already told them, then they said they couldn't find anything wrong and that I owed them for checking it out and that they didn't do that kinda of work. so why would you do an evaluation if you don't do the kinda work required to fix a problem but charge me. When I told you the problem, why not say we don't do that here and either recommend someone else or let me figure it out?

I can always trust Suntrup to make the proper repairs to my 1999 GMC SIERRA when repairs are needed. I bought the truck from them in 1999 and it had 7 miles on it when I drove it off their lot. I’ve never had to take it back a second time. The staff are polite and eager to help out with all my vehicle problems. Thank you Suntrup for being there all these years.

Took my Buick encore in twice for intermittent starting. Sorry they can't find problem plus last time I had to pay for their diagnostic! Never by a car from them! Dissatisfied customer! I am going to report them to Attorney General office! They do not honer nothing!
