Electrical system:software

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 - 2021 CLA-Class, GLA-Class, GLE-Class, GLS-Class, SLC-Class, A-Class, GT-Class, C-Class, E-Class, S-Class, CLS-Class, SL-Class, B-Class, GLB-Class, GLC-Class, and G-Class vehicles. Please refer to the Part 573 report for specific vehicle model details.

20V449000 2020-07-31

Electrical system:software

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2019 C300, C300 Coupe, CLS450, E450 Coupe and S450, 2017-2019 E300, 2018 E400 Coupe, E400 Stationwagon, and 2018-2019 S560 vehicles that have previously had the instrument cluster replaced. The software in the replaced instrument cluster may cause the seat belt warning system to not operate properly, only displaying a solid warning light if either the driver or passenger seat belt is unfastened, instead of a blinking light with an audible tone.

Without the audible tone and blinking warning light to remind the front seat occupants that their seat belts are not buckled, they may forget to buckle their seat belt, increasing their risk of injury in the event of a crash.

Exterior lighting:headlights

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2017 Mercedes-Benz E300 4Matic, E300, E43 AMG, and E400 vehicles. The headlight horizontal adjustment screws on these vehicles may not be properly sealed behind a non-removable sealing cap to keep headlights from being readjusted. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

If the headlight's horizontal aim is altered, a misaimed headlight may lead to an insufficiently illuminated roadway, which may increase the risk of a crash.

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2017 E300 4Matic, E300, and E43 AMG vehicles fitted with LED headlights. These vehicles may have misadjusted headlights, possibly resulting in the low beam headlights insufficiently illuminating the roadway. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

17V574000 2017-09-19

Steering:electric power assist system

Mercedes-Benz USA, LLC. (MBUSA) is recalling one 2017 C43 AMG, one E300 4Matic sedan, one GLC300, and one E43 AMG 4Matic sedan. These vehicles have electrical power steering control units with improperly welded contact pins.

The improperly welded pins may lose contact, deactivating the power steering assist and increasing the risk of a crash.

In owners’ own words

Fuel / propulsion 9,600 mi 4 mo in service

TL* THE CONTACT OWNS A 2017 MERCEDES-BENZ E300. WHILE DRIVING 50 MPH, THE VEHICLE LOST POWER AND ALL THE WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS ABLE TO RESTART, BUT THE FAILURE OCCURRED ON SEVERAL OCCASIONS. THE DEALER DIAGNOSED THAT THE FUEL PUMP WAS DEFECTIVE AND NEEDED REPLACEMENT. THE CONTACT WAS UNAWARE IF THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 9,600. THE VIN WAS NOT AVAILABLE.

Fuel / propulsion 70,000 mi 4.3 yr in service

STRONG SMELL OF PETROL IN THE MORNINGS, SEEMS TO BE UNDER THE HOOD. I INSPECTED THE FUEL LINES FROM THE FUEL TANK TO THE ENGINE UNDERNEATH AND COULD NOT FIND ANY DRIPS OR WETNESS. DID SOME RESEARCH ONLINE. THERE WAS A RECALL ON OTHER MODELS FOR THIS PROBLEM. I CALLED MERCEDES CUSTOMER SERVICE BUT THERE IS NOT A RECALL FOR THIS ON THE 2017 MERCEDES E300

Fuel / propulsion 33,500 mi 4.3 yr in service

LOW PRESSURE FUEL LINE NEEDED REPLACING. THIS WAS DUE TO A FUEL SMELL IN THE CABIN WHEN COLD. MERCEDES INDICATED FUEL LINES ARE CONSIDERED WEAR AND TEAR AND EVEN THOUGH IT WAS LEAKING , WAS NOT COVERED UNDER PRE OWNED WARRANTY OR RECALL. THE FUEL LINE APPEARS CRACKED DUE TO MISINSTALLATION VS RUBBER CRACKING DUE TO AGE AS ONE SIDE WAS PRISTINE AND THE OTHER HAD A CRACK IN IT. THIS IS NOTICEABLE AT IDLE , WHEN THE CAR IS COLD AND THE HEAT IS BLOWING.

Electrical system mileage not reported 1.3 yr in service crash / fire / tow

THE CAR CAUGHT ON FIRE AFTER IT BEING IN SERVICE AT THE DEALERSHIP. THE CAR WAS SENT TO THE CAR DEALERSHIP 3 TIMES BECAUSE THE AUTO START WAS NOT WORKING PROPERLY. THE CAR WOULD JUST STOP AND COULD NOT TURN BACK ON SO I HAD TO GET IT TOWED 3 TIMES...... AFTER THE LAST TIME IT CAUGHT ON FIRE WITH THE PASSENGER INSIDE THE CAR..... PASSENGER IS OK DID NOT GET HURT BUT IT WAS A VERY TRAUMATIZING EXPERIENCE. THE CAR IS NOW A TOTAL LOSS AND I'M STILL WAITING ON THE DEALERSHIP TO INVESTIGATE THE FIRE AND TO PAY FOR THE CAR.

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
