The service department changed my oil and a couple days later a low oil pressure stop engine warning came on. It went off in less than 2 seconds and didn't come on again for about 1-2 months later. I stopped my car immediately and had it taken to the dealership. They told me all of my oil had leaked out, there was a hole in my coolant container and a hole in some type of water pump. They "said" they replaced the parts and put all new oil in my car since I had practically none in it. In their words, I wouldn't have been able to drive mile down the road I was that low on oil. About two months later, I get the warning again. I took it to them, and they said my oil was low and that there was a hole in my coolant container. There's no way that's a coincidence. The people in the service department also lied on the invoice. I didn't read his comments until after I left the dealership, but he had written down my low oil light was on. The light never came on. They also didn't write where they put all new oil in my car the last time the warning came on, so they tried saying it was my fault I hadn't had an oil change in 4 months. Since they said I was low a quart of oil the second time, I left and had my dad add a quart of oil in my car. I didn't trust them to do anything to my car at that point once I found out how bad they tried screwing me over. Once my dad added oil, the warning light went off. About three days later, my car broke down. Now they're not going to fix their mistake because them adding all new oil wasn't "recorded" on the paper. I added how much they said I was low, and yes it was the correct oil. So, I did what they were going to do. Besides, I didn't need an oil change yet. If they went by the last time they added all new oil, I would've been under the recommended mileage for an oil change that was listed on a maintenance spreadsheet on chevy's website. I shouldn't have been low on oil at all. But since it wasn't written down on the papers, they said I was "over the mileage." Another dealership put in a claim about this incident to gm and gm referred back to premier's invoice. Since premier didn't put down that I had all new oil in my car, gm denied covering it. I'm never buying a chevy from here again because I can't put up with these clowns at Premier. All Premier does is lie and cover up their mistakes.
