The 2009MERCEDES-BENZC350 carries 96 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 1 crash, 0 fires, 1 injury, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2009 C350 is air bags with 25 filings, followed by steering (20) and electrical system (15). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.

NHTSA currently has 15 investigation files overlapping the 2009 C350. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Vehicle has lost its ability to be driven. Car alarm has gone of a multitude of times at different hours of day and night. Finally we were told that the steering column needs to be replaced. According to tow truck driver, Auto lock person, this is common from the 300 series of Mercedes Benz. Obviously very costly. My car is worthless at this point. I believe that the Mercedes Benz should have a recall on the steering column lock. Obviously, this is not only a defect but, also causing safety issues with it just turning off and not able to restart.

20240905SERVICE BRAKES

Rear brake lines corroded leading to loss of brake fluid while on the road. My at the time 4 year old son and I were in the car (I was the driver). This was in December of 2022 so almost two years ago. Earlier that year, MB dealership warned me about rear sub frame being corroded, too, but the cost of repairs ($7,000) were out of reach. There were no warning signs the day brake line started leaking other than a dashboard message to check the brake fluid and I felt I could not really stop my car. Car was taken to a local shop and the rear brake lines were repaired for $1,158. on 12/12/2022. Then this spring 2024 rear sub frame fell apart while switching my winter wheels to all year wheels/tires. MB USA honored this repair through the extended warranty.

20230710SERVICE BRAKES

Total shutdown of complete system…brakes, steering and engine at around 25-to 30 MPH. No warning. Happened two times…once before M-B service and once after service for problem. It checked out OK from dealership months before only to have it happen again. Was lucky to avoid a crash both times. Sold to dealership. Wrote my safety concerns for a new owner to local dealership and corporate.

REAR SUBFRAME RUSTED THROUGH ON BOTH SIDES AND BROKE WHILE DRIVING ABOUT A YEAR AGO. NEARLY LOST CONTROL OF THE CAR. THERE WAS 55,000 MILES ON THE CAR AT THE TIME. ALSO, I HAVE ANOTHER VEHICLE SAME W204 CAR SERIES 120,000 MILES ON THIS CAR. VIN [XXX]. LAST WEEK THE REAR SUBFRAME BROKE ON THAT CAR WHILE DRIVING. CAME VERY CLOSE TO HAVING SERIOUS WRECK ON I77. MERCEDES REPLACED AND PAID FOR THE FIRST VEHICLES SUBFRAME. I PAID FOR THE LABOR. THEY ARE GIVING ME 30% OFF THE REPAIR OF THE ONE NOW IN THE DEALERS SHOP. I HAVE BEEN TOLD BY A MERCEDES SERVICE MANAGER THAT THIS IS A PREVALENT PROBLEM AROUND THE COUNTRY AND THAT MERCEDES KNOWS THEY HAVE A PROBLEM WITH THE SUBFRAME ON THIS MODEL. I HAVE RESEARCHED THIS ON THE WEB AND FOUND MANY OTHERS WITH THE SAME PROBLEM. THIS IS A VERY SERIOUS SAFETY ISSUE. I WOULD NOT BE SURPRISED IF SOMEONE HAS DIED FROM THIS PART FAILURE. PLEASE INVESTIGATE THIS FOR A RECALL. IT WILL SAVE SOME LIVES. REDACTED TO PROTECT PERSONALLY IDENTIFIAB

HI, ON MY COMMUTE HOME FROM WORK, I WAS GETTING READY TO EXIT THE HIGHWAY BY DECELERATING. MY CAR SWERVED AND ALMOST LOST CONTROL WHEN I BEGAN TO PRESS THE BRAKES. THERE WERE NO CARS AT 7AM ON THE WEEKEND, SO I WAS ABLE TO COAST TO THE LIGHT AT THE END OF THE 1/4 MILE EXIT RAMP. I CONTINUE HOME, BUT FEEL THE CAR KICKING OUT THE REAR END WHEN I BRAKE. AT SIGNIFICANTLY LOWER SPEEDS I LOOK IN THE MIRROR AS I BRAKE AND NOTICE MY REAR RIGHT WHEEL TURNING INWARDS. I GET HOME AND WHEN I WAKE UP I LIFTED THE CAR AND CHECKED TO SEE WHAT IT WAS. THE SAFETY ISSUE IS THAT THE REAR BRACKET WELDED TO THE CROSS MEMBER THAT HOLDS THE REAR TIE ROD CRAKED.
