My 2007 mb s550 base model stalled as I was merging on to the expressway in heavy traffic. After sitting on side of the road for 20mins, I started the car and it was making a whining noise and when I accelerate the noise gets louder. I drove the car to the nearest mercedes-benz dealership. I was told that the transmission needs to be replaced. The car has been serviced with mercedes and only has 100k miles. This will cost $7,800.00 the service guy stated that this should not be happening on this car but unfortunately he stated that he has seen this before.

What owners say
Vehicle becomes stuck in gear while driving down the road. Will not shift, sometimes you don't have enough power to move quickly. For example vehicle was stuck in 6th gear after leaving the highway. I could not accelerate to move the car. I had to shut the car off to reset the computer to get the car out of 6th gear. This has happened at least 10 times over the past 3 month period. Many other owners of this car have experienced the same transmission failure and that is very dangerous because the car lose power when it is stuck in a gear. The only way to fix the problem is to shut off the car and restart it. Mercedes benz should be held responsible for this issue.

The car stopped accelerating and then quit running. The conductor plate in the transmission failed. This is a known safety defect that mercedes-benz has ignored.
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 !!!!
