I took my Camaro in today to get the oil change done. Everything went smooth until the service was completed and when I got in my car the check engine light was on. I went back inside and spoke to Alex who came out to check the code. He told me it was on when he got in and i must have brought it in that way. I told him it was definitely not on and it had to be from them. He was very defensive and insulting and kept insisting it was not their fault. He was not even able to explain the code to me and cleared it and sent me on my way. Well 15 minutes later the light is back on so I took it too Max automotive, which is a great spot. Terry took a look at it and after about 15 minutes explained that the oil filter was improperly installed and had pinched the wiring harness nearby and that was the reason for the code. I was relieved it wasn't a major issue, but angry that Cobblestone had done a poor job and tried to blame it on the customer. The management needs to take a closer look at how customers concerns are handled. The poor customer service and poor execution of the job has left a bad taste in my mouth. This is the first and last time I will get an oil change here, and I recommend you look elsewhere before coming here.
