The service and personell were all great. However it was just too expensive for me to be able to get my car fixed after the diagnoses of the compresser needing replacing.

Vehicle was there for two days with no communication and believed they over charged for the service. The service dept. was told what the matter was they said my vehicle would be available in about 4 to 5 ho believed they over charged for the service. The service dept. was told what the matter was they said my vehicle would be available in about 4 to 5 hours. Upon closing for that they the service failed to contact me and say they didn't get to my car. I contacted them the next day and said it wasn't ready yet, but they would get to it today which never happen during business hours which they contacted me afterwards and said your car will be available for pick-up tomorrow. Went to get car and price is totally different from what was quoted from the serviceman. So I contacted two other dealers for the same issue and their price came out the same. Diamond Chevrolet compounded the labor of the job to which made the quote price go up. I asked the service advisor how can you price point the labor cost with not doing the labor for that time. Which he didn't have an answer. Therefore Diamond Chevrolet can charge an individual two or three hours of labor, but in actuality the work only takes 45 minutes to 1 hour to complete. As a consumer I believe it is the automaker to provide a standard quality of service to its customers and I feel I wasn't provided with that quality. More

Problem still exist. :( Trailer lights remains on even when engine has been turned off. My trailer works fine with other trucks. Service rep (Miguel) recommended taking my truck to another GMC dealership for repair and/or a second opinion. I’ve wasted a lot of work and personal time already and now back at square 1. More
