| My original complaint was on 08/16/2012 (number 10473170).... again, the transmission gear indicator went blank. car went into limp home mode. this time removing the key and restarting did not reset the module and i had the repair done. the repair on this was almost $2000! it was the transmission speed sensor which is part of the electrical conductor plate assembly. prior to this incident, the dealership service rep admitted that they have many repairs with transmission control problems and encouraged me to buy an extended warranty! online there are many complaints regarding the 2006- 2007 c230's with the same problem. there is clearly a defect going on and i too would like a recall investigation through the nhtsa. mb needs to admit this is a problem and recall all the vehicles with this defect. | |||

| I was stopped at a red light and when i accelerated the car didn't change from 2nd to 3nd gear and the tachometer was reading very high since i was trying to accelerate. since the car wouldn't excel i pulled over and turned off the engine. when i turned it on again it was okay. i took the car to the mercedez dealership 1/8/13 but they couldn't find a problem. this has happened a total of 4 times since 1/7/13 and each time i have to pull over and turn off the engine to reset it. additionally, i have had a problem with the car lurching (jumping) when putting it into drive or reverse and when accelerating after this the car doesn't change from 1st to 2nd gear. also, i have had 2 incidents where the car has not accelerated to the appropriate gear (higher gear) on a highway ramp and i have had to pull over and turn the engine off to reset it. sometimes when i pull over and turn the car off i have to do this again as it doesn't correct the problem the 1st time in my opinion this is a safety issue, but not only that it is very annoying and every time i get into the car i wonder whether it is going to happen again. | |||

| Tl-the contact owns a 2007 mercedes benz c230. the contact stated that the engine rpms increased to 4,000 however, the vehicle would not accelerate over 20 mph. the failure was experienced numerous times. the vehicle was taken to the dealer several times for the failure. the dealer performed a diagnostic that was unable to locate a failure code. the vehicle was taken back the dealer and a second diagnostic was performed which located the failure at the transmission conductor plate. the dealer flushed the transmission and replaced the conductor plate. the failure was not corrected. the vehicle still would not accelerate over 20 mph. the contact coasted to the shoulder, turned the engine off and restarted the vehicle in order to gain acceleration abilities. the failure mileage was 9,392 and the current mileage was 32,000. kmj | |||

| I have periodically had this problem. from a stop, the car will not accelerate. it feels like it is stuck in a higher gear. or, the opposite happens. i will accelerate, and the car will not change from second to third gear. i have to pull over and restart the engine, and then it works. i have seen numerous complaints online from other owners that they have the same problem. i took it to mb and paid 1450.34 to get the electric hydro control unit in my transmission replaced. *tr | |||

| I purchased my car brand new, it was never previously owned and directly from a mercedes benz dealer. i started having problems with speed and gear shifting back in may 2012. when driving on the freeway normal speed (55mph) the car would begin to slow down no matter how much i pressed the accelerator the car would slow to a complete stop. i would have to attempt to pull over off the freeway, turn the car completely off, let it sit and then start it again and the car would run normal. when i get off the freeway or now even when i am driving on a back road going 35 mph the car would shake as i came to a stop sign or traffic light (as if i was driving a stick shift and didn't put the car in neutral or press the clutch) and then it would shut down completely. now i am having a third issue in addition to these issues where the car will shift gears on it's own and i'm driving in automatic mode not as a 5 speed. this is completely ridiculous for me to have transmission issue on a mercedes benz that i purchased new. i took it to a dealer who claims that i have to replace the entire transmission due to one small piece within the transmission system. i have checked online and have seen that hundreds of other benz owners are having the same problems with no resolution from the manufacturer. i am requesting an investigation and a recall. this is an extreme safety hazard that a car will completely shut down while on a freeway and there have been times when i have almost collided with other cars due to the immediate decline in speed. i have to always find a way to pull over to shut off the car. i purchased this car because of the quality that it should provide. please follow up with me regarding this issue i am extremely concerned that requests are being ignored by the manufacturer and no one is looking into this matter. *tr | |||

| I was driving on the freeway and noticed that my car would not accelerate and rev high in rpm. i have to pull over on the shoulder of the freeway since i am losing control of the car. i was about to call the tow service but i recover after i restarted the engine. at the dealership, the dealer has determined to a sensor on the transmission but said since my warranty expired, i have to pay $1300 to get the sensor replaced. this is terrible since my car has only 45000 miles on it. in addition, this is a common issue based on the forum discussion and mercedes should have a recall on this issue. this is a terrible customer experience and i don't know how i can trust them. *tr | |||

| I was on the highway and the car suddenly stopped accelerating and the rpm's ran way up and the car would not accelerate. i tried putting it in neutral then drive and nothing. i pulled over turned the car off for a few min. then back on. the car operated normally. the check engine light also came on and i had all the necessary service done on the car at that time. the car has done this increasingly for the last year and it is now becoming a hazard. the car has started jumping when put in drive and it is alarming. i cannot afford to replace the transmission and i feel mercedes should take responsibility for a defect in this model. i have children and this is my only car. i don't feel safe in it anymore and my children don't either. *tr | |||

| It occurred on the freeway in stop-and-go traffic. the vehicle would not accelerate and the rpm ran high. the transmission gear indicator went blank. i had to pull over, turn the car off, let it sit, then when i restarted the vehicle, it was normal again. i had only 38,400 miles on the vehicle at the time of the failure! online there are many complaints regarding the 2006 2007 c230's with the same problem. an independent repair shop said it is perhaps the transmission speed sensor which is part of the electrical conductor plate assembly. when talking to the dealership about my vehicles camshaft sensor failure repair and possible balance shaft issues, 7 months prior to this incident, the service rep admitted that they have many repairs with transmission control problems and encouraged me to buy an extended warranty! here is a quote from an independent repair shop: these units are failing so often that the dealer has restricted selling them even in their own shop. to order a part, the dealer must submit a request with computer scans and control unit log reports of the suspected failed vehicle's electronics. the factory then sends the parts they deem necessary for the repair (conductor plate assembly, or complete valve body). there is clearly a defect going on and i too would like a recall investigation through the nhtsa. the repair on this is thousands of dollars! *tr | |||

| I have a c230 sports sedan with 45,000 miles. the transmission had been sticking in gear, but if i turned the car off and removed the key it would reset and usually be ok for a while. now it is stuck in first gear, and nothing i have tried has done any good. it will not shift out of first gear. it has an automatic manual transmission but the manual function does not work and even trying to shift manually does no good. this is a common problem with this model and yet mb has never issued a recall. this is pretty clearly a factory defect and needs to be addressed. | |||

| Car seems to stay in one gear and does not downshift or upshift when needed. the only solution is to stop car, turn off and restart. it is a risk to enter a main road because of not knowing what gear the auto trans is locked or if it will shift to another gear to get up to speed. dealer checked car once and said they could not find anything wrong but it seems it is a known issue the transmission problem for these model year. | |||

| My 2007 c230 automatic sport sedan that i purchased pre-owned and certified from an authorized mb dealer in 2009 has been experiencing problems since purchase. i have experienced extreme loss of acceleration and running at a high rpm. it first occurred a few weeks after i purchased the vehicle. i was entering a parking garage with a steep hill and as i drove up hill, the car struggled to accelerate while the rmp ran high. i feared the vehicle was about to roll backward and i quickly applied the brakes, placed the car in park with my foot still on the brake. i turned it off and restarted and was able to continue into the garage. i took the car to mb service and after they tried to say it was nothing without reviewing the vehicle, they finally agreed to do a diagnosis. i was advised they found a faulty sensor and it was repaired. several weeks later, it happened again while in the parking lot of my residential building as i attempted to back into my parking space. the vehicle did not accelerate and the rmp ran high. turning it and restarting again remedied the problem. the third and forth time it occurred on the high way during my normal commute to and from work. the issue re-appeared in busy traffic. the vehicle would not accelerate and the rpm ran high. each time it has occurred, i have had to pull over, turn the car off, let it sit, then when i restarted the vehicle, it was fine and i drove off without any problem. i have done some research on line and have found that there are numerous complaints regarding the 2006 | |||
