SERVICE BRAKES, STEERING, UNKNOWN OR OTHER
Before the incident my Mercedes started to pull away from me each time I attempted to press the brakes. At times the when I would press the brakes nothing would happen at all as if I wasn’t pressing them at all. Well on the night of February 18,2022 I was coming around a curb and when I went to press the brakes, my Mercedes began to sway slightly but the brakes never kicked in. The result of the incident totaled my vehicle, took out two transformers and a light pole, and costed me a careless operation ticket, the storage and towing of the vehicle from the incident, to the tow yard, then back home, as well as paying the ticket and having to pay the dmv. There is still an unknown amount due to demco (the energy company) for the light pole, two transformers, after hours workers and the actual worked and labor they performed. The recall flyers hadn’t been mailed out until a few months after the wreck so I had no knowledge of the issues happening nor the fact that driving the vehicle could be detrimental.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
My vehicle jerks back and forth at low acceleration, and it often goes into limp mode which makes the vehicle only drive at around 20 mph at most. I was on the highway, when this happened. I have a 722.9 transmission, and this is a common problem. Why is the snapping recalled? I have had a checked with Mercedes-Benz of music City when I had gotten my recall work done, and they said that it just needs a whole new transmission. They said that they had never seen an issue like this. They want $16,000. I have been reading and reading and reading I don't know how they have not seen the issue when it's very very common. Again my question is, why has this not been recalled? There are soldering issues for a speed solenoid sensor, and the TCU it makes it go bad. What is going on, and why has this issue not been addressed? I have two toddlers that I drive in my vehicle every single day. God forbid we're not so lucky next time. The only reason why we did not get hit this time, is because we were on the highway at a slow hour of the day. My son is disabled and we are on the highway and in the car a whole lot. If this happens during rush hour, we will be no doubt smacked into by another vehicle.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION
Both the front distronic system,which controls adaptive cruise control and emergency braking, and the blind spot warning have failed. Failure of both systems is usually caused by water getting into the respective control units related to poor sealing allowing water to enter and causing the systems to fail. I believe that these systems are critical to vehicle safety. The pre safe braking is essential to the safe operation of the vehicle. Blind spot warning failure is also a safety item on vehicles like these with large blind spot areas. Dealer has been no help other than repairs costing almost as much as the vehicle is worth. Very poor design and unsafe when these critical systems fail.

UNKNOWN OR OTHER
The center console box will jot close. I have researched and this is a common problem with this car. You can not just replace the closure part it requires a whole new box. This is at a cost of 400.00plus dollars. This is obviously a defect.

FUEL SYSTEM, GASOLINE, FUEL SYSTEM, DIESEL
The contact owns a 2014 Mercedes-Benz ML350. The contact had received notification of NHTSA Campaign Number: 22V955000 (Fuel System, Diesel, Fuel System, Gasoline). The vehicle was taken to a dealer and the recall repair was performed. Soon after the recall repair, while the contact's wife was driving 25 MPH, the vehicle stalled. The contact was unaware if any warning lights had illuminated during the failure. The vehicle was towed to an independent mechanic where it was discovered that there was moisture in the spare tire wheel well. The moisture damaged the fuel pump control unit which was linked to the recall. The contact attempted to reach the manufacturer but was unsuccessful. The vehicle was taken back to the dealer but was not repaired and remained in dealer possession. The failure mileage was unknown.

STRUCTURE:BODY
The contact owns a 2012 Mercedes-Benz ML350. The contact stated that while driving at an undisclosed speed, the vehicle stalled and lost forward propulsion. The contact turned off and restarted the vehicle. The contact drove the vehicle for a short distance and the failure reoccurred. The vehicle lost motive power and failed to restart. The vehicle was towed to an independent mechanic where the contact was informed of water entering the spare tire wheel well in the trunk of the vehicle. The contact was advised that the spare tire wheel well, was filled with water. The contact was advised to take the vehicle to the dealer for assistance. Per the dealer's records, the work associated with NHTSA campaign #22V955000 and MBUSA recall #2023010002 had been completed in March 2023. However, that recall failed to address the source of the issue where water was improperly entering the spare tire wheel well. The dealer did not maintain any records as to the status of the fuel pump or signs of water entry when the recall was completed. The manufacturer refused to cover this repair under the associated recall. The failure mileage was approximately 141,000.
