Engine misfires while driving. OBD 2 codes P0016 and P0017 indicates bad balance shaft. Common defect in these cars. Very expensive repair needed.
We received a recall notice on our Mercedes stating that over time the bonding in the glass panel and sunroof frame might deteriorate over time and cause the glass to separate from the vehicle. On 02/06/25, my son brought his car into the Mercedes dealership in Lafayette, Indiana to take care of the recall. The service tech signed off on the recall and told him everything was ok. On [XXX], he was driving down the highway and the entire glass part of the sunroof flew off behind him! Luckily there wasnât a driver behind him. He was very startled and couldâve swerved off the road causing injury to himself or others. If someone was behind him they couldâve been injured or even killed. We called the dealership immediately. The service manager told my husband that they checked the glass on the roof and our car was not part of the recall and there was nothing they could do! Since that day, (one month) we have been trying to get SOMEONE to help us. We have contacted the GM at the dea

The car randomly misfires and goes into limp mode with a flashing check engine light. This has occurred on roadways and the vehicle loses all engine power. My engine code, 272920 30 183997272.920, falls into a known range of balance shaft gear problems with this motor. There was previously a settlement by the manufacturer to repair the motor but I was unaware of this settlement before purchasing this vehicle as there was no official recall. I am being told the repair requires pulling the motor out which is quite a high cost. The problem has been confirmed by an independent mechanic inspecting the camshaft timing. There were no other indicators of this failure before the check engine light came on and flashed.
Engine pulley noises
The contact owns a 2006 Mercedes-Benz C230. The contact stated while driving approximately 30 MPH, the transmission failed to shift, and the transmission appeared to be frozen in the 2nd gear. The contact stopped and turned off the vehicle and shifted into park (P); when the vehicle was restarted and shifted into drive (D), the vehicle was lunging and jerking. The contact stated that it was difficult to shift from drive (D) to park (P) or reverse (R), because the vehicle would lunge in the direction the transmission was shifted. The contact stated that the check engine warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The contact had researched online and related the failure to the transmission control module sensor. The manufacturer had been informed of the failure. The failure mileage was 131,629.

My Engine light came on and I took it to Star Motors. They reported two codes, 1200 and 1208. This means a bad Balance Shaft. This balances the engine and controls the timing belt. I had three choices they said, Repair it for $5,900.00 ....Yes that's right. Sell the car or drive it till it dies. I asked what that meant. They said the car will just stop, freeze and size up, it could happen at anytime. So I'm driving a time bomb basically..
The timing chain failed without warning causing the vehicle to cut off while driving 75 mph on the highway. The service engine soon late was not on at all so there was no warning that something was wrong with the vehicle.
The intake manifold has a plastic tumble flap mechanism. This commonly breaks in most of these Mercedes Benz vehicles. The main problem is the high cost of repair due to it's location in the engine under a complex wiring harness. Mercedes has never issued a recall, but this problem can lead to catastrophic engine failure. This problem is very well documented on many websites.
Steering column is locked. The car will not start.
This automobile is unsafe because of the dangerous sunroof being detached.
