2006 Mercedes-Benz C230 Vehicle speed control Problems

“While driving on a city street in stop and go traffic, I noticed that the car was not shifting gears. The tachometer would rev high but the vehicle would not accelerate in accordance with the revolutions. Once traffic freed up from a stop and go 20 mile/hr the car would not shift gears and remained in limp mode. I brought the car to my mechanic who confirmed it was a transmission problem. The current quote to replace the 7 speed 722.9 transmission is $2800 parts and labor.”

“Moments after exiting the freeway and reducing speed at around 35 MPH my car did not accelerate and continue as it would in neutral. Family in the car panic and for my fortune light traffic on an usual busy street. The check engine light did not turn on at the moment of days after the incident. A week later without a warning the vehicle engine light turn on and lost speed in the freeway. This incident could easy cause my family and other drivers a fatal accident and preventable injuries. …”

“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.”

“On nov 27, 2013, I was in the los angeles area on highway 14 traveling around 70 MPH on the highway w/ many cars and my speed dropped to around 50 MPH in spite of my foot downing the accelerator to the floor. I had to turn on my emergency lights and move over to the slow lane for safety. Returning home that same day on the same freeway, the car would not accelerate or transmission would not downshift to compensate for the uphill on the freeway in spite of stepping down on the accelerator- again I had to flash my emergency lights on and move to the slow lane. …”

“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. …”
