Electrical System 7 1 injury

“Throughout the year, the car had many issues, the blind spot sensors and glass sensors didn't work, and it constantly showed that the stop/start system wasn't working. Twice, the car turned off by itself at a stoplight. Since everything is controlled through the car's large monitor, including the navigation, air conditioning, and all other functions, the monitor frequently shut off and it was necessary to turn it off and on again, or wait until the next day for it to work again. The scariest incident happened during a heavy rainstorm. I was driving on the road surrounded by other cars when my…”

Fuel/Propulsion System 4

“1. The vehicle experienced a fuel injector failure, which is part of the engine fuel delivery system. This failure appears connected to an open Fuel System Control Unit Software Update Recall (Campaign 2024080006) that has been open since May 2024 but was not performed on my vehicle, despite the vehicle being serviced at the dealership in January 2025 for other recall-related updates.

NHTSA complaint #11700351, 2025

“I recently received a notification from Mercedes-Benz concerning a safety defect in my vehicle, and to be honest, it's really concerning. The issue is with the fuel pump impeller in certain models, including mine. If this part malfunctions, it can cause the vehicle to suddenly lose power, potentially leading to accidents. Imagine driving on a highway and suddenly losing all drive power! The scariest part is that there's no immediate solution. They've informed me that the remedy isn't available yet and that they will contact me when it is. This has left me feeling unsafe every time I turn on t…”

Back Over Prevention 3 1 injury

“All on a sudden the entire screen goes blank. It has happened at least 4 times and each time the service center does some patching and it works for a few month. When it happens, all the safety features are off including reverse camera. Also, no way to set the temperature or turn of the AC. In both cases, it can lead to significant damage. The recent incident happened when I was a very busy area and without any safety feature, the car was pretty much un-drivable.”
NHTSA complaint #11647755, 2025

“When starting vehicle, center screen of vehicle was completely off and dark. Moreover, with this screen being off, you are not able to control any of the vehicle functions such as AC, Maps, Radio, Rear Camera, etc. On the other hand, on the digital speedometer screen, a warning message states "Blind Spot Assist Inoperative" and when putting the vehicle in gear, a loud beep sounds within the car and then the next warning message appears that states, "PARKTRONIC" inoperative see owners manual"”
NHTSA complaint #11628347, 2024

Lane Departure 3

“Upon starting my vehicle today the center screen did not power on. The vehicle displayed several messages indicating various safety features were unavailable, including blind spot assist, lane keeping assist, parking assist, etc. Additionally, the exterior cameras (e.g., reverse camera) were inoperable as well. Since the center screen controls the sound system and climate control system, those systems were also unavailable. I restarted the car several times but the screen remained off. I purchased this car in August 2022 and have driven it approx. 3,600 miles - this is the second time th…”

Service Brakes 2

“When I brake the car makes a clunking noise and I can feel a thumping on the brake pedal as I try and bring the car to a stop. This car is brand new. I have owned it for almost 3 weeks and it has less than 100 miles on it. You can both hear and feel the the clunk/thump as you attempt to brake the car. It seems as if it is coming from the drivers side of the car. I actually heard and felt this issue on May 23, 2022 3 days after I took delivery of the car. But I wasnt sure exactly what I felt. I haven’t Devine the car a lot until yesterday due to some medical issues I was having. Yesterda…”

Unknown Or Other 2

“I am attempting to submit a complaint against the Mercedes-Benz product and other auto manufacturers that follow this process. Mercedes provides no spare tire so this has been replaced by a "fix a flat" system that you can presumably use stop a tire air leak and then drive to a shop for repair. The fix a flat does not work when the tire is blown out or shredded so when this happens you are left with needing to have the vehicle towed to the dealership if using Mercedes' Roadside Assistance or to another shop at your own expense. Towing to a Mercedes dealership captures you to use the replace…”

Exterior Lighting 1

“Starting from the date I purchased the car, I realized dark shadows (always there) below the headlight line closer to the left and mid zone at the low beam. These shadows are actually formed within the illumination zone as if something is blocking them. I took it to the authorized Mercedes service (Hartford, New Country Mercedes-Benz, CT) and they confirmed the shadows. They told me that there are dust and scratches within the headlights, and they replaced the headlights (repair invoice is attached). However, the shadows are still present, and the service is now telling me that these shadows a…”

How we read this (methodology)

How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2022 Mercedes-Benz C-Class draws about 5.2 complaints per year on the road, ranking 13 of 15 among the Mercedes-Benz C-Class model years we have ingested (1 = most complaints per year on road).
