Media control unit screen cycles on and off while driving, causing a total loss of critical safety controls including lighting, defrosting, and reverse camera capabilities. Tesla recorded this complaint previously as a cosmetic issue and agreed to fix under warranty, only to later retract.
2016 Tesla Model S electrical complaints
Page 5 of 6: complaints 101 to 130 of 150, newest first, as owners wrote them.
The whole screen in the car is black - cant turn on AC, music, sunroof, or back up camera. Loss of rear and front view camera
Mcu1 computer failed. 2016 model s 85d. Rear camera,AC,blinkers,and many other things don't work. Car is dangerous to drive. Happened over night and I have no other choice to drive it.
Mcu failure when my car just ran out of warranty. I reported issue with car computer booting when car was in warranty last year: the power up time seems less responsive, the touchscreen became less responsive and would freeze at time. Tesla service center did a "bandaid" fix at the time. My mcu complete failure now, with no center screen, no rear camera, no signal lights which make it extremely unsafe to drive on the freeway. After waiting for appointment for 3 weeks while I have been driving my wife's car to work, I brought my car to tesla service center, told out of warranty, and also told mcu part in backorder and not available, while tesla is aware of this issue (they sent me an email last week to authorize a mcu replacement). I believe this is a design fault of the car that this mcu should be recall and replace, as I have read tesla is aware of this and upgraded a new mcu since 2018.
My mcu failed which caused a series of safety issues. The backup camera no longer works. I can not control exterior lights. I cannot use the front or rear defroster which is problematic since the AC is stuck on the on position which causes condensation to form on the windshield, but without defrost control I cannot effectively clear the window. In additional all sounds are disabled which means safety systems such as turn signals and other warnings such as forward collision warning do not work nor can these systems be adjusted.
Please add this incident to your tesla battery fires investigation. I have used the VIN from another wrecked tesla since I do not have the VIN for the tesla which burned to a crisp in this incident. Here is a report and video from the local fire department https://www.instagram.com/tv/ccztahghcru/?igshid=1dgylupmy80i0 https://www.youtube.com/watch?v=mntuzbiofty it is reported that the car was plugged in and recharging in the garage when it ignited. The fire is ferocious and continues to reignite even when the firefighters are blasting it with water. This fire could easily have killed an entire family. Please speed up your investigation into these deadly tesla cars. Thank you [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).”
Center control screen went dead. Vehicle was parked in parking lot when failure occurred.
The center console on our car died 4 years and one month after purchase (one month out of warranty). The car cannot be driven. Fortunately the car is in the garage; we have had the console die previously during driving, which is super scary. The mcu unit is bad. Our car only has 25k miles on it. Many other older teslas have had this problem.
My car's center screen console stopped working after an update. I could not reset it and so it stays blank using reset instructions from tesla. I do not have access to my turn signals, backup camera, cabin and climate controls making it less safe for the vehicle to operate. The vehicle was stationary when it happened. I believe and based on conversation with tesla this is an mcu problem with they have me pay $2500 to upgrade. I think this is an electrical systems design fault and should be subject for recall as they should know that the vehicle cannot handle data they are pushing to the vehicle via software update.
Center screen shut off while driving due to a 'mcu' failure (diagnosed by tesla service). I lost ability to control taillights, rearview camera, high beams, climate control, charging information, navigation, passenger airbag indicator. I was driving on a multi lane highway when it failed. Drivetrain, brakes and steering seem unaffected. At tesla service they tried to diagnose, and one of the resets disabled turn signals, which is a legal issue in addition to safety. The screen had rebooted several times on its own in the preceding weeks.
Mcu failure
Main control unit failed making the entire car unable to drive. This is a known issue by tesla. Every car with an mcu1 will eventually and prematurely fail.
For multiple months my center screen of my 2016 model s 90d has been freezing, displaying strange characters, taking a long time to respond, and rebooting. Upon entering my vehicle today the screen failed to turn on. After performing a reset which failed, and continuing to drive, the screen rebooted while driving. About 2 hours later, upon entering my car to drive home, the screen was again dead. The brake lights, turn signals, reverse camera, audio chimes, high beam headlights, autopilot, etc do not work. Tesla service is booked out for over a week.
The mcu failed rendering the vehicle unsafe to drive.
The main control screen has been intermittently inactive or black. Almost everything in the car is controlled by this screen. I have asked them to fix it for over two years on over six occasions with no resolution. The screen now at 64k miles is totally dead and will not restart. It disables the ability to charge the motor drive system battery, the AC heat and defroster system, control of the lights and wipers. According to thousands of web pages this issue is caused by software disabling the main file system memory chip prematurely. Telsa service wants me to pay $1146 to fix this out of warranty even though I complained about it multiple times during warranty. It makes the car useless and unsafe and there should be a factory recall issued.
Media control unit constantly rebooting while driving resulting in the loss of navigation, rearview camera, hand free, driver assist safety controls etc. Memory card failing in unit. This has been getting steadily worse over the last three months. The last occurrence was 6/30/2020.
Center screen goes dark and no access to controls during driving. It happens when backing up or randomly during driving. Tesla first sent a software update to fix the issue and scheduled a mobile technician visit. After the software they sent I was told it's taken car and cancelled the july 2nd 2020 technician visit. On 6/30/2020 after the update the screen went bland and yesterday 7/1/2020 they schedule a service center visit on the 7/17/2020 in bloomington il, they have to wait for the parts to arrive. Yesterday night 7/2/2020 I got a email that parts have been ordered, my concern is that they might use refurbished parts or use the same defective screen and I will have the same problem in future.
Ecu1 is failing. Memory chip, paint on mirror peeling.
The center screening (mcu) is defective. It often will be rebooting by itself while driving. While this does not affect the mean drive motor functions, it does affect the backup camera. Also the random reboot is distracting while driving. It is my understanding that this is a known issue with tesla mcu1 units.
My media control unit (mcu) has failed and tesla is slow to provide me a replacement. They claim that I will be provided a "refurbished unit" as soon as one becomes available. The mcu failure has impacted my cars rear backup camera, the charging system, the ability to turn on/off headlights and fogs lights, driver settings such as steering (ride selection), front crash warnings, etc. My turn signals are not responding either, and I'm gravely concerned about other safety features failing without this component being replaced. Tesla acts like it's main purpose is for media like navigation, music, etc. But as I stated, several items are direct safety hazards. Tesla knew of this mcu problem long ago and should have issued a recall for all tesla model s owners experiencing this problem.
There are two things. First the battery pack does not have the original performance as tesla slowed down supercharging and not getting the miles the battery is supposed to get with a safety update. Second the touch screen glitches and has to be reset many times and it has a common issue of the memory going bad and I am now seeing symptoms of it going bad.
The computer unit on my tesla model s occasionally either goes black or gets pixilated and turns into all kinds of rainbow colors and stops being functional. This is especially concerning because all of the vehicle information and controls are processed through the unit.
I didn't realize we can make complaints. The touch screen constantly becomes unresponsive on my tesla. I always have to reboot it in order to get it working again. System has become quite sluggish and unreliable.
In late 2019, the center touchscreen began slowing in responsiveness and freezing at times. The dashboard screen sometimes went completely black, requiring a reboot. When the center touchsreen malfunctioned, the backup camera would not come on when in reverse gear. The freezing and slow response to button presses continued to deteriorate. The whole control system (both screens) would go dark and require a reboot several times a day. Tesla claimed that they "could not reproduce" the problems. I finally paid $2500 plus tax for tesla to upgrade the main control unit from my version 1 to the newer version 2.
While driving aim freeway at 65 started having system failure. First the GPS, then air conditioning, then rear view camera, then radio. The risky one was air conditioning. Ambient temperature was 110 f. Outside of quartzsite, az.
2016 model s touchscreen went black. Required replacement. Tesla service blamed it on the computer failing.
We are also have problem with our tesla and its emmc module (flash memory in montitor, this controls everything dashboard visuals, speed etc, sunroof, HVAC, rear camera, can prevent car from starting up.
My model s has also been having screen and rear camera issues. Atleast twice a week the screen goes black then flashes back on several times especially when it is warm out. Other times the screen lags and the rear view camera either stops working or has glitches where it will pause or lag. It actually caused me to damage my car by backing into something.
The center control screen went blank and could not be rebooted. It was determined by tesla that the mcu computer failed and had to be replaced. My four year warranty had expired the previous month so the cost to replace was $1,680.25. Though the car was drivable the turn indicators would not work. You should know that this is a very common failure on all teslas that are four years old. This car only had 47,770 miles on it at failure. It failed at startup.
Car stationary. In garage mcu1 center screen dead upon start of car. Root cause is emmc chip. Car is severely impaired as much functionality is controlled via the mcu1.. Turn signals do not work. Cannot charge car at normal operating rate. Detailed impact here https://teslamotorsclub.com/tmc/posts/4672707/ tesla is making customers replace defective mcu1 with same part that also has the same mcu1 with same emmc that is known to fail over time.
