Broken rear subframe because of rust and corrosion with perforation. Manufacturer refused to cover the repair.
Steering, Apr 30, 2026
The contact owns a 2006 Mercedes-Benz C230. The contact stated that while driving at an undisclosed speed, the steering wheel became loose and landed in the contact's lap. The steering wheel failed to lock securely in place. The contact was able to drive to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.

While driving at approximately 70 mph on a highway, the rear subframe of the vehicle suddenly and catastrophically failed. This caused the vehicle to fishtail violently and nearly led to a serious highway accident. I was able to regain control and pull off the road safely, but the vehicle was no longer drivable and had to be towed. An inspection by a certified technician confirmed that the rear subframe rusted from the inside and experienced a complete structural failure. One of the suspension control arms even broke off of the subframe due to rust. The vehicle showed no warning lights or symptoms prior to the incident. The road was dry and free of potholes or debris, and the car had been properly maintained and garage-kept for the prior 16 years. This issue is a known defect in Mercedes-Benz vehicles of similar design. Mercedes-Benz has extended the subframe warranty for C-Class vehicles from model years 2008–2015 due to widespread internal subframe corrosion. However, this vehicle (2006 model year) is not covered, despite experiencing the same failure. The corrosion originated from inside the subframe, indicating a manufacturing or materials defect rather than environmental exposure. This failure posed a severe risk to my safety and the safety of others, especially since it occurred at highway speeds without warning. The problem has been documented in other vehicles and is the subject of a current class-action lawsuit (Case § 1:23-cv-00636 in the state of Georgia).

Engine misfires while driving. OBD 2 codes P0016 and P0017 indicates bad balance shaft. Common defect in these cars. Very expensive repair needed.
Engine, May 29, 2025
The balance shaft sprocket in this car needs to be recalled. It has has known issues since it came out nearly 20 years ago. It can cause your whole engine to blow if not fixed. The fix is often more than the value of the car, around $7000. It is ridiculous. The part was not properly heat treated during manufacture which causes it to fail prematurely at the expense of the owner.

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 02/21/25, he was driving down the highway and the entire glass part of the sunroof flew off behind him! Luckily there wasn’t a driver behind him. He was very startled and could’ve swerved off the road causing injury to himself or others. If someone was behind him they could’ve 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 dealership, talked to 3 people at Mercedes corporate only to be hung up on once and put on hold for 45 minutes the other time. To this day we are unable to get anyone to address the issue. The NHTSA clearly stated our vehicle is part of this recall yet the dealership is stating the glass number wasn’t listed. Obviously our vehicle is part of the recall considering what happened!

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.

Our car was recalled on 07/03/2008, recall #08V303000, for problems relating to a number of types of mechanical and electrical malfunctions. One was the "(3) OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND (4) THE SPEEDODOMETER MAY BE OUT OF TOLERANCE" This vehicle has had a malfunctioning "CHECK ENGINE LIGHT", that needs to be corrected. It prevents the car from being properly registered, and the warning being on is a distraction to drivers. It has been unresolved by Mercedes and by other mechanics who could not make the proper repair of the "Check Engine Light" issue that was listed in the recall. Mercedes has failed to make the repair, associated with this recall and states that the recall #08V303000 of 07/03/2008 is expired. The car had had recent additional recall work done, and this problem was brought up, but not addressed nor corrected by Mercedes. There has been difficulty in our obtaining Connecticut vehicle emissions approval, and Connecticut registration renewal due to the unaddressed problem by Mercedes. We cannot re-register the vehicle out of Connecticut until this issue is resolved. If we chose the sale of the vehicle, we would have to provide the purchaser a clear and registerable vehicle. Without your assistance in the resolution of this matter that would be impossible to do.

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..

I PURCHASED MY CAR IN 2018. THE BALANCE SHAFT GEAR HAS A RECALL AND THE MANUFACTURER IS NOT HONORING THE RECALL WITHOUT AN EXTENSION FROM THE MERECEDES BENZ COMPANY. AS WELL MY MOON ROOF NEED THE BONDING REPAIR AND IT IS SHOWING A RECALL IN THE SYSTEM

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.

At 9,000 miles my 2006 Mercedes C350 had to have a fuel pump replaced. It was out of warranty (low miles usage for 5 year old car) so I had to pay $900 for the repair. I could smell fuel everytime I filled the tank and the Mercedes dealer said the pump had to be replaced. I read about a recall of E350 models being recalled for the same reason with the same engine. I asked the dealer about this and they said mine was not part of the recall because it is a C class Mercedes. It has the same engine with the same problem and I think this should be looked into.

I have a 2006 Mercedes C280 which I purchased almost a year ago with 57,000 miles. It currently has 73,000 miles and is having major mechanical problems which have been life threatening due to when and where they occur. 1. Loss of transmission upon acceleration. If I pull over, turn it off and restart, it will shift fine until it decides it wants to do it again and I either lose the ability to shift, or it goes into limp mode without a Check engine light. This has happened on the freeway, heavy traffic, and have been several close calls. The shop said the codes were for transmission malfunction and valve body malfunction. Just out of nowhere. 2. Check engine light goes on and off repeatedly and The plastic intake manifold needs to be replaced because it is one of the defects Mercedes was sued for on this particular year, model, and engine. All of the oxygen sensors are going out as well and that is just the start. The cost for the part alone is in the $1000 range. My mechanic said the best is yet to come and explained around my current mileage on up is when most of the damage takes place with the valves and whatever else happened with this engine. I'm not sure exactly what all the problems were but he said to take it to the junkyard and was very serious which infuriates me because it's a beautiful car and I couldn't in good conscience sell it to anyone. Mercedes is fully aware of this but not a lot of people benefited from the settlement. The same problems are known by all owners and German mechanics.

We have 71,000 miles on our 2006 Mercedes Benz C280. Before Christmas, the engine light starts going on and the engine starts sounding rough and jerking. We take it into Mercedes Benz and they diagnose a cam shaft issue. It turns out all 2006 Mercedes Benz C280 have the same problem with the same mileage. This car is a safety hazard and needs to be recalled.

This automobile is unsafe because of the dangerous sunroof being detached.
