I was driving home and noticed that when I would accelerate after coming to a stop the car was extremely slugglish. I would have to almost floor the gas pedal in order for the car to begin moving. I pulled over and then put the car in neuttral. The jerked violently and shifted very hard as I then tried to put it in reverse and the into park. I tried to put the car back into drive and it would not accelerate at all. I had to turn the car off and then back on again in order to get it moving. The gears continued to shift violently. However, when I finally got moving again, the car would not go over 35 MPH. The car was inspected and an error code for the internal speed sensor came up, which is part of the valve body for the transmission. My car only has 59,000 miles on it. Mercedes is very aware of this problem on 2006-2007 c230 models! In fact, they are having a dispute with the manufacturer of the valve body because it is poor quality and defective. I have seen numerous other complaints related to this issue. My local mercedes dealership quoted me $2,400 to repair this defective part. I was lucky in that I was not driving at 60 MPH on the highway when this malfunction occurred. This is an extremely dangerous issue and a recall should be issued for this part.

Having problem with the gear shifting, believe this is caused by the shaft balancer, etc. The car grabs and jerks from time to time making me unsure of the safety of my car. My car only has 84,000 miles on it. The car is like new, but as I read the class act against mercedes I noticed that my car has several of the same issues as others listed in the complaint. The interior and exterior of my car is in excellent condition, and I can't believe that the mercedes company would allow an error like this to continue. I would like for this to be corrected by mercedes or to be placed on the class act suit as well.

Periodically the car would lose acceleration and rpms would be high and the vehicle would jerk when I tried changing gears. As I change gears from park, reverse or drive, the gear shift jerks and I am unable to accelerate past 20 MPH no matter how much pressure I place on the gas. : extreme loss of acceleration up hill and the steptronic (+/- shifting) did not work... (I could only go 35mph when every one else was going 70mph up hill) when I traveled on a flat surface with no inclination my car worked fine, I then decided to put it on neutral while traveling at 65mph...when I put it back in drive it did not pick up the gears it just continued as if it was in neautral. I had to pull over and shift it into park...as I shifted form "d" to neutral it shifted fine, but then from neutral to "r" the car jerked...from reverse to "p" it jerked again and shifted hard. I then shifted again to reverse, neutral, and drive thus the car jerked and did a hard shift with knocking noise and would not drive. I shifted to neutral again and shut the car off. When I turned it back on it shifted smooth and I drove off without any problem. Took it to a repair shop and received p0717/p0718 fault codes and something about the valve body. I was also told that it was an transmission internal speed sensor issue. There is something faulty with the design and operation of this model year transmission and losing power and being able to only go 35 MPH no matter how much you press the gas on the interstate or heavy fast moving traffic is extremely dangerous. Mercedes benz is aware of this problem as many owners have complained but they will not institute a recall.

The transmission internal speed sensor failed indicating that the valve body needs replacing. The gears are not shifting properly and get stuck. I have to pull over and turn the car off for about 10 minutes to let everything reset and then ok to drive. If I do not stop and turn car off and put it into park with engine still on and try to shift back into drive it is a hard shift and then the car will jerk. I saw on line all the complaints with the same problems for the c230 sport.

I was driving my vehicle on the highway during morning rush hour when I noticed that the car would not accelerate over 35 MPH. I moved the car off the highway and stopped at a red light. Once I stopped the car it would not accelerate at all when I stepped on the gas. I had to put the car in park and then move it back to drive to get the car to move. The car would jump and lurch forward when I shifted gears. I drove the car directly to the dealer. The mercedes dealer told me that there was a problem with the software and that the software would need to be updated. I went to pick up my car after the "software " was updated ($1,700 cost) and drove the car about 10 miles when I noticed that the check engine light had come on. I took the car back to the mercedes dealer to let them know the check engine light was now on. The mercedes dealer told me I have a defective balance shaft that needs to be repaired. The mercedes dealer ask me if I had kept up the oil changes on the car. I told the them that I had. The mercedes dealer told me that I have to pay $2,500 just for them to take the engine apart and that the total repair will cost around $6,000. I just purchased the car in july 2010 ( 14 months ownership) with about 19,500 miles on it.
