POWER TRAIN,ELECTRICAL SYSTEM,ENGINE

1 complaint

While driving my lease vehicle on two separate days, it completely shut down while in motion with no prior warning. The first incident occurred while crossing a MAX train intersection in downtown Portland. The engine stopped mid intersection, emitted a strong mechanical odor, ticking noises began, and dashboard alerts appeared. I could not restart or shift the vehicle into neutral. It was stuck, blocking the intersection. Although hazard lights were flashing, the vehicle appeared completely undamaged, so other drivers didn’t realize it was disabled. Police were called to the scene, and we had to remain alert for oncoming trains and traffic weaving around us. Four days later, while driving about 30 MPH on Murray Boulevard near Cornell Rd, a 4-lane hwy near a freeway off-ramp the car failed again in the exact same way. The engine shut down in active traffic. The smell, ticking sounds, and dashboard messages all returned. The vehicle once again would not shift into neutral or respond to restarts. This failure happened with traffic traveling 30-45MPH. Despite police presence and hazard lights, multiple near-accidents occurred because the vehicle looked fully intact and other drivers didn’t understand it was inoperable. Mercedes-Benz claimed this was a starter motor issue, which is inaccurate. A starter motor does not cause a moving vehicle to shut off, nor does it lock out neutral. These symptoms point to a critical failure of the powertrain or electrical system. Most alarming is the inability to manually override the system and move the vehicle to safety. Bystanders and even police were unable to shift or push it. This is a serious design flaw that turns a technical malfunction into a dangerous roadside emergency. This vehicle was in pristine condition with no damage or misuse. I kept up with all maintenance and care. Technology should never prevent human intervention during failure. These incidents placed lives at serious risk.

BACK OVER PREVENTION

1 complaint

Rear view camera says it is inoperative when I put it in reverse. I understand that a number of Mercedes models have been recalled due to a software issue but the dealer tells me my car is not on the list. The problem I have is identical to the other models. My car should be on the list

SEAT BELTS

1 complaint

The driver’s seatbelt failed to properly engage during a high-speed rear-end collision allowing his head and face to strike the steering wheel causing a loss of consciousness and other symptoms of traumatic brain injury. Thus far the problem has not been reproduced or confirmed by a dealer but it is believed the seat belt was inspected by EMTs responding to the scene. Additional documentation will be provided when received. There were no warnings or other symptoms of the problem prior to the failure. This report is filed on behalf of the owner and driver by their attorney.

VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

1 complaint

Traveling at 65 MPH in the right-hand lane * Driving Assistance ON * Traffic Sign Assist ON * Speed Limit Adoption ON Staying in the right-hand lane, I pass by an offramp Sudden deceleration to 20 MPH – Phantom braking This has happened twice traveling past the same offramp. Since, I have turned the Speed Limit Adoption OFF Note that this particular off ramp has more than one speed limit sign (yellow) visible from the freeway. My guess is that the Mercedes is reading the off ramp signs and interpreting them to be for the freeway and not for the off ramp. I consider the sudden deceleration to be dangerous
