AIR BAGS

1 injured · crash · towed

I was involved in a severe front-end collision where my vehicle struck another vehicle with significant force. Despite the major impact, the front airbags did NOT deploy. The entire front end of the vehicle was crushed, including destruction of the radiator, damage to engine components, internal structural collapse, and leaking fluids. Based on the severity and direct frontal nature of the crash, airbags should have deployed but did not. As a result of the impact, I sustained a neck and upper shoulder injury and required medical evaluation. There were no warning lights or messages prior to the crash indicating any malfunction in the airbag or SRS system. The vehicle is available for

FUEL/PROPULSION SYSTEM
My 2022 Mercedes-Benz GLC 300 (17,700 total miles) suffered a catastrophic structural engine block failure and an explosive loss of propulsion while driving at highway speeds. This occurred exactly 6 days and 183 miles after a franchised Mercedes-Benz dealership performed the official fuel pump impeller safety recall (NHTSA Campaign 23V-445).The dealership's official repair invoice documents that the technician custom-modified the recall remedy by reusing parts, explicitly stating: 'Relocated floater from old pump onto new fuel pump.' Simultaneously with the mechanical engine failure, a 'Reduce Engine Oil Level' message flashed on the dashboard, indicating severe fuel dilution from the

VEHICLE SPEED CONTROL
I have experienced 4 incidents of the car accelerating on its own. I have taken it to the dealership twice and they are unable to reproduce the problem. Problems began occurring in 2025 and occurred again this past week (August 20246). In the most recent incident I was accelerating on an "on ramp". The car suddenly took hold and continued to speed up despite my foot not being on the gas. I had to drive the car to safety with my foot on the break. The moment I took my foot off the break it would speed up. The floor mat was not touching the gas in all of the instances of this occurring. The gas pedal was not stuck to anything. I nearly avoided a serious accident as where i was trying to merge

ELECTRICAL SYSTEM
While driving down a busy neighborhood street 2 lanes with cars on both sides making it a 1 lane road pulled over to the side a little to let cars pass. All of a sudden ALL electrical and engine stopped and turned off. Only thing that was powered was instrument cluster with multiple warnings like SRS Malfunction, Steering Malfunction, SOS Inoperative, Parking Brake and more. We believe the car had also shifted to park on its own. No power to anything not even hazard lights. Nothing electrical had any sort of power. Could not even turn car off completely could not get the instrument cluster to turn off with ignition button. When I say everything electrical had no power I mean everything

ELECTRICAL SYSTEM
My vehicle got stuck on a EPB(electronic parking brake) and I was unable to disengage it. I tried a few things and none worked. I contacted Mercedes to tow it to the dealer and the tow truck came and driver had to “drag” my vehicle on to the flatbed. My car has been at Mercedes for 5 days now and they gave me a response saying that they are having a hard time trying to disengage the EPB. I’m aware of a EPB recall but my model is specified as being a part of it, however the issue is closely related to the recall so please take further interest in my situation because it could be the start of a new recall. The dealer says they have tried and failed to disengage it. My car was working just

FUEL/PROPULSION SYSTEM
I was driving back to my house in york, PA. My car all the sudden changed the gear from “D” to “N”. My gas meter was showing 106 miles. my didn’t give sign or alert before it shifted the gear from D to N. I was driving on highway and this was major safety concern as I could have hit by cars coming on highway speed. We had this similar incident last year as well but we were at traffic light stopped so we didn’t realize that time that car shift the grear by itself. Once we fill the gas, we were able to drive back home but it was scary and big safety concern that car doesn’t give any notification or alert for low fuel and change gear all the sudden.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
