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.

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

LI54.70-P-080191

BACK OVER PREVENTION: WARNINGS; STRUCTURE:BODY

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. Typically only small adjustments are possible. 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.

LI35.30-P-058566

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).

Complaint Service code B1 displayed in the customer menu does not match the workshop code displayed in the workshop menu, e.g., 505 or 550A, which includes a service A. Cause The root cause is currently being investigated. Remedy To determine the cause, the instrument cluster control unit (N133/1) and powertrain control unit (N127) logs are required before confirming the service or correction using XENTRY Diagnosis. Please open a TIPS case to BCE inbox with the requested information in the attachments.

Complaint After successful commissioning of the HERMES control unit (N112/9) with XENTRY Diagnosis DVD 03/2026, the message "SOS - service not activated" appears on the instrument cluster. In addition, the following two conditions are also met: • HERMES (N112/9) control unit: event code B15CE00 is ACTIVE and STORED (A+S) • Vehicle Documentation System: For the HERMES control unit, the EID1, EID2, ICCID, IMEI, IMSI, TELNR fields in the "Identification/Serial number" column have the value "-" Cause Still under analysis Remedy Recommission the HERMES control unit (N112/9) with XENTRY Diagnosis 03/2026 and add-on 33399 installed or carry out the procedure with a newer version of XENTRY Diagnosis: XENTRY→ "N112/9 - Control unit for telematics services (HERMES)" -> "Adaptations" -> "Control unit commissioning" -> "Commissioning of previously installed control unit"

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.
