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.

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 restart. Waited 5 minutes car started and we drove it to Walter's. The week before I had it back in the service department because the finger print function was not working any longer. They supposedly replaced the software package and then this major issue happen. The service department at Walter's has tried at least two times to download a new software package however this vehicle is not allowing it to accept it. They said engineers from the East coast were trying to help but nothing has been accomplished. It is becoming frustrating and allowing the overall safety concern has been increasing for my wife and I. What if this happens again and we are on the freeway or a street with traffic which both situations could cause a severe accident and harm.

I was driving and all of a sudden a loud sound started occurring and the sound appeared to come from my breaks as if they were about to give out. The car is currently at Mercedes getting looked at. I’m concerned for my safety as I have taken this car in for two other issues in the last couple of months.

Within the first week of ownership (delivery on 1/15/24), the car's parking and/or front collision sensors started malfunctioning on a regular basis. The sensors repeatedly gave off false alerts when the car would approach intersections even though no obstacles were in front of, or behind, the car. The false alerts were quite startling and they consisted of loud alarms and warning images in both the driver's display and the car's heads up display. The repeated false alarms posed a significant safety hazard because they initially caused me to slam on the brakes risking a rear end collision. Once I realized the sensors were malfunctioning, I started to ignore them which is equally dangerous if a real collision needed to be averted. The car is currently in the service department, and it has been there for a total of 29 days thus far. It was initially thought that a software update would resolve the problem, but that did not work. After the software update was completed, a new "parktronic" module was installed. That also did not solve the issue. I am now being advised that the car is issuing fault codes related to the airbag system. It seems that there are some serious electrical problems that are plaguing the vehicle. The service department has advised me that they have no clear date on when this issue will be resolved.
