Went to do my transmition oil change and it turns out that my car had to stay there for 3 days. After one day they called me to pick up my car and went I drove out of the dealer my car shut down completely. The mechanics there don't know what they're doing and the worst part is that the service director Patrick Collins is the type of person that wouldn't give good customer service and I'll quote him " I wouldn't expect you to understand because you're not a mechanic" well I don't need to be a mechanic to know that from a job takes an hour 1/2 it took them 3 days to fix what they have done. After all inconvenience and since my car doesn't have warranty anymore I still had to paid everything out of pocket and when I asked the to at least at extended warranty on the car Mr. Collins said absolutely not because they had to replace my coils for free...coils that they messed up during the oil change. It's unfortunate that on top of the 900.00 I had to pay now I have to spend money on attorneys to have a resolution on this matter.
