AIR BAGS

crash · towed

Issue: Post-Airbag Deployment PCM Lockout Description: I am reporting a critical safety concern regarding the 2024 Mercedes-Benz C300. After an airbag deployment, the vehicle's Powertrain Control Module (PCM) is designed to automatically lock, preventing the engine from being restarted. While this feature is intended to enhance safety, it poses significant risks in certain emergency situations. For instance, in scenarios such as a landslide, attempted robbery, or a collision with wildlife in a remote area with poor cell signal, this design could leave the driver stranded without the ability to restart the vehicle and drive to safety. The inability to restart the vehicle could result in

SERVICE BRAKES

crash · towed

The vehicle appears to have experienced a braking system malfunction, possibly involving the brake-by-wire system, electronic stability control (ESC), or unintended acceleration event. When the brake pedal was fully depressed, the car suddenly and uncontrollably accelerated forward into a cinder block wall. After the incident, it was observed that only the left-side tires left skid marks, indicating an apparent brake imbalance or failure on the right side. The vehicle is available for inspection upon request. My safety and the safety of others were severely compromised. My daughter and I were in the car during this and are extremely traumatized. Despite pressing the brake pedal, the vehicle

ELECTRICAL SYSTEM
While I am driving my car it will make a loud crackling sound then my screens go black and warning sounds go off! This is not normal and I read there are recalls but when I entered my vin# nothing came up. Not to mention since I bought the car last February, I have had nothing but issues with my AC turning off which that I have taken to the dealership with video proof and told it was a software update which did not fix the issue. i am paying way too much money for a newer vehicle and having more issues than my 2015 Mercedes Cla 250.

NHTSA complaint 11749373. Filed by an owner and not verified by NHTSA or by us.

UNKNOWN OR OTHER
The car jerks so hard at times randomly that it feels like I got rear ended and it is completely unsafe. It also does small jerks at times. It's happened driving 70 mph down a highway, making a right turn accelerating slowly. Going slow down the street at 35, at a red light completely stopped or stop sign. There's no rhyme or reason to it. I've taken it to Mercedes five or six times now with the same issue and they have not been able to duplicate the problem. It's currently at Jacksonville Mercedes dealership where I bought it with the foreman. He is with my permission driving it back and forth to work because I said I do not want the car back until they can duplicate the problem and fix it

ELECTRICAL SYSTEM
On Friday [XXX] at approximately [XXX]. My wife and I were driving our 2024 C-Class 300 (~8,000 miles on this vehicle) on [XXX] and entering the intersection of [XXX]. Riverside, CA 92506 when all of sudden the car just died (the engine stopped running, pushing the gas pedal with no power) and all the dashboard lights came on flashing like crazy. This incident paced my wife and I in a very venerable bad not safe situation. If there was any traffic at in this intersection at that moment it would have been a bad situation. I called MB Walter's they could hear the sounds which were loud and they ask me to open and close the doors to see if sound would stop and wait 5 minutes and try to

SEATS
The driver’s seat in my car moves backward on its own while I’m driving. I’ve taken the car to the dealership several times, but the issue still hasn’t been resolved. This is extremely dangerous and frightening. It has happened twice on the highway, Several times in the dealership’s garage, And most recently, while I was pulling out of a parking spot: Half of my car was still in the parking area and the other half was already in the street. The road had a curve, so other drivers couldn’t see me until they got very close, which could have caused a serious accident. This is a serious safety concern that needs immediate attention.

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.
