Horrible! The front desk girl in service told my insurance company there’s no way an accident could have caused a sensor malfunction… I was hit HEAD ON. They then proceeded to take over a week to do the repair that I was told “only took a few hours once we got to it”. Charged me multiple “diagnosis fees” on top of the work. No loaner, no rental and I’m out $500. Avoid. This dealership is slimy and scammy.

Misdiagnosed the problem, I had to tell them what to look for, engaged my insurance, they repaired, picked up car with check engine light, they pulled code, said it had a bad battery but no battery warning light, then I asked what the engine code was for, they said it was for a bad canister purge valve and couldn’t fix it until the following week for $258, I checked it and some one had disconnected the wire harness to the valve that had nothing to do with the repair.

Just bought a new Buick 2026 in February battery went out technical issues. They came for the truck this past Thursday the 14 of August and no loner car or called us back Monday and still we are without a car for some reason they don't wanna lend us car even though we're paying less than $900 a month for that Buick it is frustrating. Supposedly today they haven't even touched it because they haven't diagnosed the problem imagine 5 days without a Car. And we're still waiting that's why I'm Posting this to see if a manager or someone That has authority to make a decision and help the customer will call us. Frustrating what's happening to us.

Joshua Love is the reason I purchased my truck from Wiesner GMC. He acknowledged my presence and assisted me every step of the way. Allowed me to decide on the vehicle I wanted without pressure. An absolute pleasure to work with. And the easiest purchase yet at a dealer. Highly recommend Joshua and Wiesner. Thank you finance team. You too were a cut above.

I have purchased 3 vehicles there in the past 3 yrs. Also a Chevy at buckelew for my son. I purchased extended warranties for them as well. Both the gmc 1500 and the Chevy 1500 had torque converters go out in the past month with similar mileage. GMC uses a 3rd party called rosemark for extended warranty. Long story short it covered nothing and wiesner did nothing. Cost me $3200. Buckelew now keating covered the repair and even gave us a rental. Obviously there should be a recall on these trucks as this is a similar problem that is happening all around but the difference is where you purchase and what warranty they sell and whether they back it or not. Wiesner did nothing. I called rosemark warranty and they read me the manual which states you have to flush the transmission fluid at 45k miles which we didn’t so that was their way out of the repair. They also noted that when we did our oil change that it was a recommended service. Recommended doesn’t mean required to keep warranty in my eyes or else we would have done it. Another out for warranty company to deny us. I asked for a refund and they wouldn’t do that either. If you are going to buy from wiesner I suggest you not get the extended warranty they push on you especially if it’s from rosemark which is not told at time of purchase.
