2007 Mercedes Benz C280

June 2, 2025 To Mercedes Customer Service: Safety Issue. This weekend I experienced the most frightening encounter that I ever had in a car. As I was driving on a 4-lane bypass highway at 55MPH my car suddenly and erratically turned to the right almost sending me into the cement bridge guards (I was driving over a river bridge). As I tried to correct the car, it then veered sharply left sending me into the passing lane where other traffic needed to avoid hitting me. Then after the car was stabilized “ESP inoperable” light came on. I had nowhere to pull off on this particular highway and had to continue to drive until I got to an exit. Took to my dealership. Apparently cause is “broken subframe” Not knowing what that meant, I looked it up, only to find a longstanding problem in Mercedes vehicles. I feel fortunate to have avoided a serious accident/injuries. But I have to say I am disappointed in the Mercedes response to this issue and the recall which only focuses on particular years and models impacted by the issue. Subframes, meant to last the lifetime of the car, have been a recurring issue with Mercedes. Apparently the class action law suit covered cars 2010 to 2022 and so even though what happened to me (sudden severe and erratic swerving) is identical to that described in the class action findings and recalls, and my car is still within the 20 year timeframe for free repairs up until 2027, I do not qualify simply because my car is 2007. (~$3500 bill coming my way) I see no logical explanation as to why all cars experiencing a subframe corrosion and breakage would not be covered by the same recall regardless of the year of the car. How is that logical? (Car is still in repair shop. no invoice available yet.)

I am writing about this incident after finding out about the lawsuit filed against Mercedes concerning problems with the balance shaft, the soft metal they used in production, and the COMMON engine codes (P0016 & P0017). I am [XXX] and I was on the highway with my girlfriend going around 75mph and I smelled a burning smell and thought it might’ve been the truck/one of the cars in front of me. All of a sudden my power steering was gone and my car basically lost all power. Only the brakes worked. Thank god the other cars were far enough away from me and I didn’t put anyone else in danger. Due to the loss of control I was forced to pull into the breakdown lane on the LEFT side which was so incredibly dangerous since the highway was so busy. I eventually pulled to the right side of the highway when there was enough space and time to do so and opened my hood and saw that my tensioner blew and the serpentine belt came off. I was so angry because the dealer that sold me the car told me the codes were only emission related and did not affect the mechanics of the car. That’s a whole other issue. I am not so very mechanically inclined but after extensive research I’ve found that this code (which was covered up by Mercedes) was most likely the culprit and has been causing me issues throughout my experience with the vehicle. I am a broke college student. Yes, it was stupid to buy a Mercedes, but I was [XXX] and I’ve learned a lot about cars and the industry since then. At the end of the day, despite my stupidity and ignorance, Mercedes should be held responsible for this issue and everyone who has [had incidents similar to myself or have the codes that I have deserve to be reimbursed for all the repairs, time, and danger they have and will eventually put people in. Don't wait for someone to die on the highway before you consider issuing a recall. DO SOMETHING. I shouldn’t have to fear for my life going out in this car to get to work, school, and most importantly, my family. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

I first noticed an issue with the alignment. The vehicle would always pull to the left. After 3 different alignment procedures, it remind the same. I started noticing a clunking sound when I would brake. While driving I hit a moderate pothole and the car lurched side to side, causing me to lose control. It was fortunate that I was on a surface street, and that I was only traveling about 35 mph. I almost struck the vehicle next to me, but my quick reflex prevented it. I limped the car, going 15-20 mph with hazards on, to my mechanic. He called me the next day informing me that I had a complete rear subframe failure. I researched and found that Mercedes, had extended the warranty on all models of the same year but my model was not included. Numerous mercedes of the same year and model are having the same issue. This is an EXTREMELY and dangerous issue that Mercedes need to address. Others my not be so fortunate as I was to have been on a surface road under speed. I would not have been able to control the vehicle had I been traveling at highway speed.

Everytime I fill the gas tank I smell gas strongly I paid out of pocket to have the fuel pump done the gas cap the purge valve and I’m still getting a check engine light for a evap leak and still smelling gas from inside and outside the car I also have a rattle noise comeing from inside the gas tank u can take the gas cap off and heat it inside the gas tank from outside and inside the car it’s a constant knocking noise inside the gas tank I replaced everything and their is still a knock noise and fuel smell I have proof receipts from Merceds dealer of all work I did and I have videos of the noise I can’t afford a new gas tank I bought the car in Connecticut with a 2 year extended warranty the warranty place won’t cover a new gas tank I saw their were recalls for gas smells on other models same year as mine but not the c class a lot of other people I noticed on google have had this same knocking noise and fuel smell the car only has 70 thousand miles on it I can’t afford 5 grand for a new gas tank and labor espically after I already paid for all this stuff and already had this problem diagnosed but yet everytime I get my car back it’s never fixed but they tell me it’s fixed they have my car for months at a time and never give it back to me fixed I’m always paying for rental cars because of this they won’t supply me with a loaner please put a recall in for these fuel tanks 2007 c280 4 matic only has 70 thousand miles I bought it 4 months ago and no one will fix this properly for me when they have diagnosed this problem multiple times the rattle is the baffles in the fuel tank they keep working their way around it and keep telling me it’s other things just to get my money instead of properly diagnosing it I’m just sick of geting my car back saying it’s fixed when it’s not out of the 4 months I’ve had this car it has Ben in my possession for maybe one of them the other 3 months it’s Ben in and out the shop for the same problem please recall these tanks car has low miles

On 9/18/23 we were hit head on by a person driving a large ford. The air bags deployed on my CClass. I was unable to see after the accident. My nose is huge! Face is bruised. I had severe eye pain. Neck pain etc. There was chrome on the floor after the deployment. Major concern what was in this airbag. However, I’m sure it saved my life. My car is totaled. It was a fabulous car. We had scheduled a sunroof recall next week at Mercedes in New London, CT. I learned of this recall after my car recently past emissions. My car only had 39,000 miles. I’m going to miss it.

Engine Control Unit failed during warranty after replacement by the Mercedes Benz Dealership. The ECU causes stumbling and cutting out of engine in traffic while driving which can cause an accident putting my self, wife and others at risk. I took the car to the dealership and showed them the stored code of 1596 “The engine off time has an implausible value” (P1026) on the Mercedes Benz Xentry DAS software. Yes: the dealer inspected the car and did a diagnostic. The code was cleared and the dealer claimed there was no code. A CHECK ENGINE LIGHT was present when the problem started approximately 23 months after the ECU was replaced be the dealer with a two year advertised and communicated warranty.
