Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

I PURCHASED THIS CAR IN NOVEMBER OF 2012 AS THE 2ND OWNER. IT ONLY HAD 60,000 MILES ON IT AND SEEMED LIKE A GREAT CAR. ONE DAY I WAS DRIVING ON THE FREEWAY APPROXIMATELY 65MPH, WHEN I HAD TO BRAKE SLIGHTLY AND THE BRAKE PEDAL FELT KINDA MUSHY AND MY BRAKING WAS SLOWER THAN NORMAL. NEXT THING I SAW WAS MY DASHBOARD HAD A RED MESSAGE ON IT (BRAKE REDUCED BRAKING EFFORT) AHHHHHH I WAS FREAKED OUT AND GOT OFF THE FREEWAY AND PULLED INTO A GAS STATION. I CALLED A TOW TRUCK (I WAS AFRAID MY BRAKES WERE NOT GOING TO WORK AND I DIDN'T WANT TO PUT MY YOUNG SON OR ANYONE ELSE IN DANGER. THE BENZ DEALERSHIP DID A FULL INSPECTION AND FOUND THAT THE SBC (SENSOTRONIC BRAKE CONTROL SYSTEM) NEEDED TO BE REPLACED. THE ALSO STATED THAT MB HAD A RECALL ON THIS PARTICULAR PART, HOWEVER THAT I MISSED THE THE FRAME TO GET IT REPLACED. I CALLED THE MB CORPORATION AND SPOKE TO SEVERAL SERVICE REPS AND THEY ALL TOLD ME I SHOULD HAVE GOTTEN IT REPLACED WITHIN THE RECALL TIME FRAME OF 10 YEARS. I EXPLAINED HOW COULD I HAVE KNOWN THIS WHEN I PURCHASED THE CAR AND I WOULD LIKE FOR MB TO REPLACE MY SBC UNIT OR AT LEAST GIVE ME A DISCOUNT. ANYWAY, AFTER 3 MONTHS OF CALLING AND RECEIVING NO ASSISTANCE, I GAVE UP. I DO NOT THINK THIS IS A WAY TO RUN A BUSINESS, ESPECIALLY WHEN IT A MAJOR SAFETY CONCERN. THEY KNOW THAT THIS SBC UNIT CAN AND DOES DEFAULT TO BASIC HYDRAULIC MODE, WHICH MAKES BRAKING SLOW AND UNSAFE. NEEDLESS TO SAY THE CAR IS USELESS TO ME AND HAS SAT IN MY DRIVEWAY AS THE ELECTRICAL SYSTEM GOES OFF AND ON AS I AM DRIVING. I WILL NEVER BUY ANOTHER MERCEDES BENZ, I BOUGHT IT FOR THE SAFETY OF MY FAMILY AND NOW I SEE HOW MUCH THEY STAND BEHIND THEIR PRODUCTS...I WILL ALSO NEVER PURCHASE ANOTHER CAR AGAIN WITHOUT CHECKING THIS SITE FOR RECALLS.

LI54.70-P-080191

BACK OVER PREVENTION: WARNINGS; FORWARD COLLISION AVOIDANCE: WARNINGS

Complaint Consistently reproducible erroneous parktronic warnings from front with every key cycle. Cause The parking sensors are detecting the front brush guard. Remedy Complaint must be consistently reproducible and can occur multiple times a key cycle without obvious cause. NOTE: The parking system serves solely as an aid. Please review both the system function and system limitations as shown in the Operator's Manual. Certain environmental factors can affect system functionality such as hot exhaust gases or extreme heat, sensor interference, or other outside influences or aftermarket modifications. If after verifying the complaint is consistently reproducible: 1. Determine if the complaint is reproducible only in high ambient temperatures. If complaint does not occur in cooler ambient temperatures, it is due to system limitations. You may proceed with the below work but the vehicle may be released afterwards as it is due to system limitations. 2. Remove the brush guard and verify the park distance sensors function as expected. 3. Reinstall brush guard and adjust so that it is as far away from the park sensors as possible. This typically means moving the bar further away at the bottom and closer at the top. 4. Check function. If the concern is still consistently reproducible, please apply clear matte film to the locations as shown below at a minimum, although the clear matte film may be applied to the whole brush guard. Picture: Above shown is the 465 brush guard variant. Although similar to the 463, there are some key differences such as the 465 being fitted with a front camera.

STRUCTURE:BODY

Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Information: Please refer to this document in the warranty claim and, after completing diagnosis, select the damage code corresponding to the component part that caused the problem. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10-P-067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

POWER TRAIN

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
