2021 Mercedes-Benz A-Class Powertrain & Transmission Problems

this is a formal notification regarding my vehicle that I purchased at House Of Imports on February 27, 2021. A Mercedes Benz A-Class 220 year 2021, VIN #W1K3G4EB7MJ290124. Shortly after purchase I experienced several safety concerns about the vehicle. The first and main concern are while driving vehicle the accelerator stopped working ,vehicle would not move forward or back which put my life in a dangerous situation due to this isssue that occured while on a main street with incoming traffic. Immediately I made an a report with dealer and car was taken to dealership ( House Of Imports) . The advisor told me it was a software issue and they updated the system which they said vehicle will not have that issue again. Several things were replaced which ai have the repair documents. The second issue with the vehicle was about 3 weeks from this date today I turned on my vehicle to exit my garage I put the gear on Reverse and it did not move , I tried to move thr car forward meaning putting the gear on Drive and still nothing happened, after several attempts nothing happened. I decided to turn off the vehicle and a few hours later turned it back on and I was able to drive. The third issue was just last week January 19, 2026 I turned on vehicle to exit my garage and again the car would not move back or forward. I tried changing gears multiple times for about 20 minutes but car never moved it seemed completely stuck. The following day I had to get the car towed to House Of Imports, and it has been at dealer since then. Due to this situation I no longer feel safe driving the vehicle, I don't consider the vehicle is in proper safety functioning condition and it's not corresponding to the value paid. For this matter I respectfully request an immediate solution.

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.
