2021 Mercedes-Benz A-Class POWER TRAIN,UNKNOWN OR OTHER

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.
