Rearview System Braking Problems of 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.

Tesla’s software updates have rendered systems useless the vehicle wants to hug and sometimes cross the left double yellow lines. It cannot hold a constant speed and since their implementation of “supervised” full self driving, have made my vehicle unsafe.

The screen that shows the rear view camera turns on intermittently when engaged. It will often not turn on when shipped to reverse. The sentry system has stopped working as well as the main screen will shut off while driving from time to time, which removes the ability to turn on any heat or air, defroster etc. . . This was a previous recall and I am a new purchaser of the vehicle. I notified Tesla, they stated that they see where it is having issues but it was already recalled and fixed and any new fixes are no longer under the recall.

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.

1)mcu1 flash memory failure in production from 2012 to 2018, part is available, but would require downing the car to remove/replace. 2)the symptoms of this failure include the loss of indicated gear state and reduced driver visibility from the loss of rearview camera, defrost/defog and exterior signal lighting which increases the risk of an accident. Driver display is black or booting up slowly during this time and the car can be put into gear and driven prior to the display showing dnr gear state making it a safety risk to anyone walking near the vehicle if it was accidently put into gear. 3)issue was confirmed by Tesla and was told an update to mcu2 hardware at $2250 was needed at the customer (my) expense. The vehicle was under a full Tesla warranty, so I refused and asked them to fix this issue. Tesla service cleared/freed up some memory but said the issue would return unless I paid to update to mcu2 hardware. The issue has returned as they stated. 4)yes, by Tesla service and Tesla engineering. Both confirmed that this was a known issue with the mcu1 hardware in production from 2012 to 2018 and recommended that I (the customer) update the vehicle to mcu2 hardware for $2250. 5)there are no warning lamps or messages to inform the operator of an issue. Only the black driver display, but that doesn’t prevent the operator from putting the vehicle in gear. The symptoms start with slow driver display boot times and progressively get worse over time losing the rearview camera, defrost/defog and exterior lighting controls. The display lag becomes enough to be able to accidently put the car in drive or reverse without displaying indicated gear state on the dash making it a safety risk to anyone walking near the car.

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.

Tesla is not replacing the emmc card that has been recalled in a timely manner as they are required to.

My Tesla is experiencing the mcu problems outlined in NHTSA ea20-003 from 13 Jan 21 and prior. While in motion, on city streets and highways, and regardless of speed, my vehicle's mcu will spontaneously and at random intervals freeze. This results in loss of heat/cooling, front and rear defrosters, infotainment/gps, adas safety features and convenience, all cameras including backup camera, and turn signal audio indicators. The only resolution is to stop my vehicle, issue a reboot command, and wait up to 10 minutes for systems to restore. Tesla initially denied the issue, but then under Tesla's 9 Nov 2020 "warranty adjustment program" replaced the mcu daughterboard. The replacement did not resolve the issue. Tesla now states the mcu is operating normally but acknowledges that a fix is required in software that will, at an indeterminate time, become available and that until such a fix is released, system reboots should be performed as needed. The mcu continues to freeze while driving with the same symptoms as before the daughterboard replacement. The recommended solution to reboot cannot be performed while driving but must be performed immediately to restore safety functionality. Tesla has offered a $2,500 mcu replacement/upgrade that promises to eliminate the issue since the newer mcu has more storage and an intel atom cpu instead of a slower nvidia cpu. Tesla refuses to replace the existing mcu with a similar part in the meantime, despite initially acknowledging an issue and attempting a fix by replacing the daughterboard, and erasing the system due to possible "corruption" twice.

The mcu screen goes blank repeatedly. It requires a reboot. When this occurs loss of numerous vehicle functions occurs which creates safety issues. Control of defogging, rear back up camera etc are some of the last safety features. Currently has only occurred in stationary vehicle.
