Purchased an 2001 Audio (used) at d & s auto and within a week there was screeching noise coming from the engine, engine light came on. Brought it back to d & s auto. D & s auto had it looked at and they said the list of problems were none found, only that they fixed the engine light. Couple days later the engine light came back on and also the rear back tire was making a strange noise. D & s auto made an appointment for the 2001 auto to go to another dealer to be looked at. Also, purchased the best full warranty on the vehicle. The dealer printed out a list of problems which are listed above he said that are problems and the cost was going to be around $3,000. 00 and that the warranty does not cover any of the repairs.
