C240 Noise, Vibration & Harshness
Here's my tale of woe:
Two weeks ago I took delivery of a 2005 Certified Preowned C240 Wagon with 9850 miles on the odo. Prior to delivery, I noticed a resonance/vibration that could be heard and felt at 45MPH, was pronounced at 50MPH and gone by 55MPH. The vibration could be heard and felt throughout the car. The salesperson said it might have been flat spots in the tires and noted it in a "we owe" so that if it didn't go away, it would be on record for the service department to fix under warranty.
Over the course of a week I put nearly 1,000 highway miles on the car. Over that time, I noticed that while the resonance/vibration went away at 55MPH, it came back stronger at 80MPH and above. I brought the car back to the dealer for that and for a wheel alignment problem (pulling to the right), both of which should have been corrected before the car was listed for sale as a CPO vehicle.
After three days in the shop, I picked the car up and noticed that while the alignment problem had been fixed, the vibration had not. While the noise was the same, the vibration moved to the steering wheel. Supposedly, all the suspension and driveline components were checked and found to be within factory specs. They rotated the Continental tires (which might explain the vibration moving from the seat to the steering wheel), re-indexed the tires to the wheels and force-load balanced them on the advanced Hunter balancing machine.
After three more days in the shop and a new set of tires (Continentals again), I got the car back today. I was told that the shop foreman and the QC specialist had driven it and declared it to be perfect. I drove it and found it to be exactly the same as the day I took delivery.
At this point, I am extremely frustrated. When I took delivery, I knew it wasn't a tire problem. Looking back, I should have made them fix the car before I took it. Regardless, here I am now, about to go to the General Manager and insist that he take the car back and replace it or refund my money.
Anyone have any experience with a similar problem, any advice on how to deal with the GM or any thoughts in general?
