Rearview System Braking problems of the 2016 Tesla Model S

My 2016 Tesla Model S (45,500 miles) is experiencing a complete failure of the media control unit (mcu1), resulting in a total loss of the rearview camera display and defrost/defogging controls. This is a critical safety hazard. The unit was previously replaced by Tesla in 2021 under NHTSA recall 21v-035. However, this replacement part has failed again after only a few years of low-mileage use. Tesla service is refusing to provide a free repair or a goodwill discount for an mcu2 upgrade, claiming the 'recall repair' only had a 1-year warranty. It is unacceptable that a safety-critical component replaced under a federal recall fails twice in 45,000 miles. Tesla has failed to provide a permanent fix for the emmc defect identified by NHTSA. By refusing to restore the camera functionality without charging full price, Tesla is knowingly allowing a safety defect to persist. I request an investigation into these premature failures of recall-replaced components.

Speedometer went completely blank and not able to see anything on that which includes safety features like blind spot monitoring and land departure. Also multiple time screen freezing issue causing absence of rear view camera.

I backed my Tesla out of my driveway on 12/17. I could see as I backed into the street another car at the stop sign waiting to turn left. I was blocking part of the road so as the car was in reverse moving back, I put my Tesla in "d". I clearly saw the d. I stepped on accelerator seeing they were patiently waiting and I wanted to get out of their way. As I touched gas I was in shock-I kept going in reverse! the car dash said "d" and in my shock I pressed down on the gas more. I ended up accelerating more in reverse and smashed right into a parked car on the street! I knew I was swerving back and steered into the middle of the street I thought. I never heard the warning sign on my car because it was in d. I didnt see the car in my rearview mirror and in the shock of the speed and my correct into the middle of the road, I dented my neighbors front left bumper only. Thankfully I didn't damage their lights. It only did a small scrape in the front right rear side of my Model S. I did replicate the problem one more time on camera about 15 minutes later. But I was in such shock the camera drops below the road so it has my voice on it and I didn't want to hit someone else again. This is very dangerous to accelerate backwards when the dash says "d". I've taken the Tesla in many times for the screens freezing. They say its memory issues and want me to pay 2500 to upgrade the internal parts. This puts my kids and anyone at risk if they're behind me when im shifting to drive and drive off. There again were no warnings before the crash because the car was in d.
