One Star – Extremely Disappointed with Ron Carter Chevrolet & GMC Service Department

In January 2025, we brought our 2019 Buick Enclave to Ron Carter’s service department because the A/C was not circulating properly in the front of the vehicle. The passenger side had some airflow, but the driver’s side had almost none. We never reported any issues with the rear A/C—only the front.

After diagnostics, we were told the rear evap core was leaking, even though we specifically explained that the issue was with the front A/C. Since my wife and I are not mechanics, we trusted their word and agreed to the recommended repair. That repair cost us just over $3,900 and came with a warranty.

By April, the same issue persisted—it was still noticeably weak on the driver’s side. We should have taken it back then, but since it was cooling somewhat, we waited. Eventually, the A/C went back to performing exactly as it did before the repair, so we brought it back under warranty.

This time, they claimed the front evap core was leaking and wanted another $3,900 to fix it (later offering to reduce it to $3,200). Essentially, they charged us thousands of dollars to replace a part that never addressed the actual problem we reported. Now they refuse to honor the warranty because it only applies to the rear evap core—the part they insisted needed replacing, even though the issue was clearly with the front system all along.

To add to the frustration, they also quoted me over $700 to fix a check engine light for a purge valve issue—only for it to turn out that the part was still under warranty. If I hadn’t pushed, I might have been wrongly charged for that too.

In short:

They misdiagnosed the problem. (When I was taking the car to another service department the information I received was that the front and back evaporator will not show the exact same symptoms when failing, the location is the key. We specifically made them aware that the front was not cooling, which indicates a problem with the front evap core)

They performed an unnecessary $3,900 repair that didn’t fix the issue.

They refuse to stand by their work when the original problem returned.

They attempted to charge for a warranty-covered part.

We feel taken advantage of, and I would strongly caution others against trusting this service department.

Also, believe it or not they still charged us a service fee of $189.99 to basically tell us we spent over $3900 and they didn't fix our issue.

take their 2.8 star...

I would give zero stars if it would let me. Took my wife’s Terrain in for a simple oil change and tire rotation. There was a check engine light on for a faulty O2 sensor. The light had been on for a couple of weeks and I was planning to have it replaced but didn’t want a dealership to replace it. The service guy called me to tell me my oil change was complete after a couple of hours and tried to sell me on having them replace the engine filter and cabin air filter. When he told me the price, each replacement was almost triple what each filter costs at Autozone so I politely declined and said I would do them, and the O2 sensor, myself. I pick up the car and make it a few miles down the road to H‑E‑B on 528. When pulling up to the gas pump, the car starts shaking side to side and RPM’s start fluctuating like crazy. The traction control lights came on and a “Service Engine Immediately” alert came on the dash. Accelerator lost pressure and I was pretty much a sitting duck. The engine continues shaking and a rattling sound begins. This car barely has 70,000 miles on it and is normally the smoothest, quietest car. I eventually make it to the gas pump and notice a lug nut on my rear left wheel is hanging on by a thread. I tighten by hand and limp the car back to the dealership. When I arrived, they hook the car up to the reader. Now there was an engine misfire code. When I ask the guy what in the world they did to my car, he suggested it was mere coincidence. I am not a car guy, but have been told by multiple people, more knowledgeable about cars than me, that a faulty O2 sensor would not cause these symptoms. I was told that I would have to pay for a diagnosis (real convenient) but they would expedite me to the front of the line and I’d hear something back in a day or two. On the third day, I was heading out of town but I started to inquire about their progress. I made several phone calls and left several messages. It is impossible to get someone on the phone there. When I return from my trip, it has now been 8 days and no call back. I go to pick up the car to take it somewhere else, and find out they never had a record of it being there. The service agent had to go searching for the keys and vehicle. This place is a joke. I wouldn’t let these bums wash my car let alone work on it. Please do not bring your...

This was the single most disappointing visit I've ever had. Where do I start. I had to town my own vehicle to the shop and was informed it would take a day to diagnose the issue. So after, dropping it off, proceeded to Enterprise rent a car, to get a rental. I was told it cost over $200.00 to get a vehicle. Went back over to service and found out the dealership has new owners and no longer help with rentals when you bring your vehicle in for repairs in their shop. Fortunately, I did get something. I had to call the next day to find out my car battery wasn't holding a charge. I decided i was going to but my own battery, since it was going to cost me about $220.00 . Got a battery the next day and drove back out to the dealership , to get a call stating I bought the wrong battery. So, i told them just put in the 1 they had. I was told they should call me that afternoon when it was ready. Drive back out there and waited hours and still no call. Called the dealership and asked for service and finally found out it was waiting for me. 3 days of frustration over a dead battery and terrible shop service. I would rather take my car somewhere else and spend more than returning to back there ever again !!!! I even got a call about my service experience and told them what happened. I was told the shop manager was going to call me and still no call in over a week !!! This was my second and last car ever being purchased from this dealership....
