I purchased an Audi from Beck Evans. Within 24 hours of the purchase, the car was running at 50% power and the brakes were squeaking. I returned the car and found that the brakes needed replacing and that the timing was out. They worked on the car for a few days and returned it to me. Within a week of having the car back i began to hear a squeaking/knocking noise. I was unsure what this noise was until a member of the public informed me that my wheel wasn't straight. I pulled over and realised that 4 out of 5 wheel bolts on the front wheel were not there. There was one remaining which was loose. The remaining bolt was not the locking wheel nut (which eliminates the possibility of a theft attempt). Had I not stopped when I did the wheel would have come off of the car putting me and other road users in severe danger. The technician working on my car clearly hadn't tightened the wheel bolts correctly. I added wheel bolts but the car is still has a knocking and isn't running smoothly. The loose wheel has potentially damaged the vehicle. Further problems include: 1) Lacquer peaking from rear bumper from recent repair (by Beck Evans?) 2) The electric windows don't work intermittently 3) Air con system smells and requires disinfecting I called Beck Evans yesterday morning and was promised a call back from an owner the same day. I chased the call in the afternoon and was told that the owner was out buying cars but would call me back soon. The call still hasn't happened I bought from a dealer for added convenience. I didn't expect this service from a large prestige dealer. Not only have I had several mechanical problems, negligence has resulted in a situation that could have resulted in serious injury.
