As we were driving 50mph, the car stalled and lost all power. The dashboard lights all lit up and the car wouldn't start. I don't get unnerved easily and it was fairly intense not being able to move your car out of traffic. After about 5 mins, the car would start again only to stop a minute or so later. After taking the car to the dealer, the issue stemmed from the fuel pump electronics board getting wet in the spare tire wheel well where water was accumulating. This was part of the recall and the dealer installed a drain and replaced the board. HOWEVER, this issue again happened nearly one year later in our next rainy season. After taking it to the dealer, they said WE would need to replace the electronics board ourselves. We asked about the recall and they said they fixed the issue by installing the drain plug and there was nothing else they could do for us. Even the service adjuster was upset and very sympathetic to our plight as the car was obviously not fixed. Even though the drain plug was installed, the water was still acumulating in the wheel well. It seems apparent to me, and several others who have complained about the same issue, that the recall fix has not addressed the main issue of why the water is coming in and why it's still not draining. Unfortunately we're going to have to fork over $1200 to have it fixed. My ask to the NHTSA is that this issue be readdressed with Mercedes. I would like them to be notified that the recall does not address the underlying issues and the solution they provided does not fix the problem. I appreciate your time in considering this.

Vehicle: 2014 Mercedes-Benz ML350 VIN: [XXX] I have experienced repeated failures of the Blind Spot Assist / driver-assist system since purchasing this vehicle. When I first purchased the ML350 in Texas, the vehicle already showed warning messages (“Blind Spot Assist Inoperative / Pre-Safe Function Limited”). The dealer attempted repairs before delivery, but the defect persisted. After moving to New York, the problem continued. On June 26, 2023, I took the vehicle to The Automaster Mercedes-Benz in Shelburne, VT. Their diagnosis confirmed water intrusion into the blind spot radar sensors, consistent with Mercedes-Benz TSB LI54.71-P-056477. Both left and right sensors and wiring require replacement. This is a safety defect because Blind Spot Assist and Pre-Safe features are disabled without warning, increasing risk of collision when changing lanes. Many other owners have reported the same issue, and Mercedes has issued a TSB acknowledging the defect, but no recall has been provided. I request that NHTSA investigate this recurring safety problem and require Mercedes-Benz to provide coverage or a recall for affected vehicles.

I purchased a used Mercedes-Benz from Freehold Mitsubishi in early 2024. Within hours, serious safety issues appeared, including a check engine light, cylinder misfire, EVAP leak, traction control failure, and blind spot assist malfunction. The vehicle’s ECM and wiring harness were later found damaged due to oil leaks and electrical shorts. Despite multiple repair attempts, the vehicle was returned in worse condition and remains unsafe to drive. I am reporting these issues due to their potential risk to vehicle safety.
