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. Due to an irregularity stemming from the molding process of the fuel filter flange, the fuel filter flange may crack when operated in high temperatures.

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.

Defect. Mercedes-Benz USA, LLC (Mercedes Benz) is recalling certain model year 2011-2012 S550, S550 CGI, S63, S600 Bi-Turbo, S65 AMG, S550 4-Matic, and S550 CGI 4-Matic and S400 Hybrid vehicles manufactured from March 3, 2011, through July 30, 2011, for failing to comply with the requirements of Federal Motor Vehicles Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring System (TPMS)." The tire pressure monitoring system indicators may only illuminate for a portion of the time required by the standard and under certain conditions may not re-illuminate immediately after the vehicle is restarted as required.

Risk. If all four wheel sensors in the subject vehicles are simultaneously malfunctioning or missing, the TPMS will provide an initial warning, but this warning will not automatically repeat on subsequent ignition cycles, failing to remind the driver that the system is offline. Driving unknowingly with incorrectly inflated tires may result in sudden tire failure, increasing the risk of a crash.

Remedy. Mercedes Benz will notify owners, and dealers will reprogram the tire pressure monitoring unit, free of charge. The recall began on September 12, 2014. Owners may contact Mercedes Benz at 1-800-367-6372.

I bought a 2011 MB S400 last year. Everything was good till 3 months ago. I smelled a very bad gas leak one day and it gets worse after I fuel my thank. Nobody wants to seat my car after I buy a gas. I realized there is a gas on my driveway under my passenger seat. When I googled it, there is a recall for MB W221 for 2011 models because of the Fuel Filter parts problem. It's not designed for the heat. Somehow, some 2011 s are not part of this recall, and MB doesn't stand on their car even have the same problem. I removed the back seat and everywhere was gasoline because of the crooked fuel filter part. Protective layer was in so many pieces because of the heat. When I wrote the MB, they refused the replace the part, they didn't accept their safety problem that happened for 2011 MB W221 S class. Currently, I wait their respond. It is so sad, they refuse to replace 100$ part in part of recall. Be careful if you buy a MB, it is not designed for the heat, and MB refuses to replace the problematic fuel filter. Currently, I wait the day to replace the part, or I will be in fire because I drive with a gasoline leak every day. Look at the picture, it is a Mercedes Benz S Class with leaking because of the bad fuel filter design !

Reading this record

No unusual pattern of severe incidents in the complaint record.

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.
