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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 Mercedes-benz C-class Hybrid verdict →
