Defect. Mercedes-Benz is recalling certain model year 2011-2012 S400, S550, S550 4Matic, S63 AMG, C300, C300 4Matic, E350, GLK350, GLK350 4Matic, CL550 4Matic, and CL63 AMG vehicles manufactured from April 18, 2011, through July 12, 2011.

Risk. If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.
Remedy. Mercedes-Benz will notify owners, and dealers will replace the fuel filter, free of charge. The recall campaign is expected to begin in February 2013. Owners may contact Mercedes-Benz at 1-800-367-6372.

Rear brakes backing plates rotted prematurely despite garage kept and well maintained status. While driving, noticed loud scraping and grinding noises from the rear left wheel. Took to mechanic and he found severe rust, with deep corrosion and flaking "rotted". He said I was lucky because this was very close to causing the entire brake assembly to fail, which would lead to serious braking problems or "locked out wheel" and loss of control on a highway which would have put me and others at risk. Had similar rust issues with this car that were fixed in the recent past including rusted brake lines and rusted rear subframe. There is definitely something wrong with the manufacturing as the rear subframe had been recalled and got it fixed that way less than a year ago.

Car was Off and parked when brake line failed. Further inspection was able to identify that brake pipes was slowly corroded thought entire lower part of the brake system causing critical failure of brakes. Extreme safety issue due to the material of metal/coating and position of brake pipping. If operator was not observant, operator/driver would not have any braking and could cause harm.

The driver’s side door handle broke and I was unable to leave the car unless it was unlocked and rolled the window down to open it from the outside through the window. If there was a loss of power and you pulled on the latch and it broke you would be delayed in exiting. There are multiple videos on after market parts to repair the plastic pin that breaks. Tesla seems to be recalling their vehicles for a similar problem recently, why not Mercedes for a known problem????

The electronic steering wheel lock went out causing the car to not start. Upon checking the Internet to see if anyone else was having this problem I found that it was a problem many Mercedes Benz owners have had and it's an expensive one. It's not just with my particular model and it's not limited to older models of the brand either.

I drove vehicle to Publix with no problems. When i tried to start vehicle, key turns but car does not start. There is no cranking sound. I called a mechanic friend and after extensive diagnosis he determined it was the ESL Module which controls the steering. Fortunately i was not driving the vehicle when the ESL Module failed. There is a recall on Mercedes Benz c300 from 2012-2017 for the ESL Module problems but the 2011 is not included. It should be recalled since it is a safety hazard and it appears others have had similar problems according to comments on Google. I have a handicapped wife i take care of and having issues with the steering can cause accidents and injuries. There were no messages or symptoms of the problem prior to the failure. There needs to be a recall or further inspection done on the 2011 Mercedes Benz c300. Car will be towed to a Mercedes Benz dealership for Diagnostics.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it’s going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards. Yes, the vehicle is available for further inspection upon request immediately each day my life is at risk. 2.How was your safety or the safety of others put at risk? My safety and other's safety are put at risk every time I get out on the road to drive my car it's putting me and other' live in serious danger (especially with the extreme increase in car accidents in the local Nashville, TN area). Despite the vehicle now being 3,000 miles over the 150,000-mile extended warranty threshold.

I just purchased a 2011 Mercedes C300. I was told that for the past 2-3 years the vehicle would constantly bald out the rear 2 tires and would need replaced every 3 months. As I was driving the vehicle I noticed that the rear tires would make weird noises as if it was hutting something. Upon further investigation the rear sub frame is rotted, which based on research appears to be a very common problem with these vehicles. The rear sub frame is rotted in which caused the lower control arms to completely rot off of the frame posing as a serious safety issue for me when driving with my children and a safety issues for others when I drive on the road. On top of that due to the lower control arms completely rotting off the frame it caused the control arms to hit the gas tank which could catch the car on fire. Mercedes has refused to issue this as a recall in due part to their negligence. Customers cannot afford to pay $5000 for a rotted subframe due to negligence from Mercedes. Please research how many vehicles have had rotted subframes for this vehicle. In Germany they will repair the rotted subframe free of charge. Mercedes needs to be held accountable for risking peoples lives.

While I was driving, my seat back suddenly started reclining backward. I could not make the seat stop or go forward with pushing the power seat button control. It kept reclining back, pushing into the back seat and would not stop until there was no power left. Had my child been in the seat behind me, instead of behind the passenger seat, her legs would have been crushed.

Interior door handle becomes inoperative due to breaking of some internal element. This prevents leaving the vehicle. Of concern is that in case of emergency, the occupant cannot exit the vehicle. If power is affected, the windows cannot be lowered which is the only way to exit using the exterior door handle. This is a well known defect of this series of Mercedes Benz to which the manufacturer has not accepted responsibility.
Complaint volume is well above typical for a single model year.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
