Well not too excited or thrilled about the purchas...

Well not too excited or thrilled about the purchase as of now. I did buy a pre-owned Audi A4 and my sales associate reaffirmed me that the vehicles are inspected and have no issues what so ever. One day in of owning and driving the vehicle a sensor goes off and an hour later another sensor in the display pops up. Now it is flashing like a christmas tree. So it starts with these problems and I'm not sure they really inspect or check the vehicles here correctly. I'm trying to get a hold of the sales rep who assured me no issues and I get no answer from him looks like once you buy a pre-owned vehicle your on your own.
