Four problems related to transmission stuck in gear have been reported for the 2007 Mercedes Benz C230. The most recently reported issues are listed below.
My vehicle became stuck on one gear as I entered the freeway. I had my kids with me and I had to pull over the shoulder. After turning it off and on again, it reset itself. This has happened 4 times now. Now its happening on stop lights as I try to accelerate, it feels its dragging and cars behind me are honking at me to move out of the way. It is unsafe and I cant afford to fix it or buy another one. I researched and found much more people are having this problem. Why has no one done anything about this issue? my wife drives this car and I am not sure if she will respond in the same fashion as I did when presented with this dangerous event if it occurs. I wanted someone with some clout to know about this just in case a disaster occurs I know who to go after. Please make Mercedes Benz responsible and fix this free of charge. This is my only car and it was not cheap and now to pay for a problem I am sure they know is a problem. . . . Its ridiculous. Please help before someone gets hurt. Just look up 2007 Mercedes Benz C230 stuck on gear and you will see how big this issue is. I bought the car in January 2016.
Before I brought my vehicle to the shop I had experienced this transmission issue several times, all resulting in my car getting stuck in a gear. If I pulled over and restarted my car, everything would work fine. I did not have a check engine light error, but I ran the code with my obdi checker, and received an error in regards to the speed sensor. After some research of this issue, it appeared to be a known issue with this type a car. I took the car into a local transmission shop and the repairs totaled $1450. Please note that the local shop still had to take the car to the mercedes dealership and get the part programmed (tow to dealership $147 and programming $211. 20). Since this is a wide spread known issue, why is mercedes providing a reasonable remedy, thank you.
My transmission became stuck in a high gear and would not accelerate. Could not manually change gears and the only way to remedy this issue was to park and turn off the car. I had to use my hazard flashers and drive in traffic for a few miles until I could get over to the shoulder of the road. This is very dangerous and troublesome to me. It appears to be a common issue on this site as well, please look into this.
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.
