The contact owns a 2007 Mercedes-Benz S550. The contact stated that while driving at various speeds and trying to place the vehicle into a different gear, it would not move. The vehicle was able to shift after a few moments of waiting. The vehicle was inspected by a dealer who advised him that they were unable to diagnose or duplicate the failure. The failure occurred on an intermittent basis since 2008. He also stated that while slowing down and shifting into first gear, the vehicle would suddenly surge forward. The vehicle was inspected but the failure could not be duplicated. The failure mileage was approximately 6,000 and the current mileage was approximately 22,000. The VIN was unavailable.

Without any warning the transmission went out on 2007 Mercedes S550 with only 40,000 miles on it. I purchased the vehicle brand new and had maintained service with Mercedes and had all the records. The car was a few months out of the manufactures warranty yet I been very well maintained and had low mileage considering I bought it when they first came out in 2006. Mercedes did everything possible to say I had not properly serviced vehicle until I produced all the records, thought they had a system that traced service sine all work was performed by them. The customer service was very rude and I ended up paying to have transmission replaced. I hope the customer service guy can buy a S series. It's the last one I will ever buy !!!!
