36 Electrical System problem

Failure Date: 12/01/2020

I own 2 Teslas (2013 s and 2016 x) and within 6 weeks both center screens went blank. The stated reasons by Tesla for the defect for the s is listed as "ms tegra mcu lte prem w-d motherboard na(1004740- 10-a)" and for the x it's listed as "mcu, mdlsx, na premium, remain (64gb)(1098010-99-h)". I'm convinced it's a built-in flaw that should be covered by Tesla vs the owners. Also, upon my request to send me the diagnostic logs that would allow me to verify wether it's truly the motherboard or the SC card that is defect, Tesla refused to do so. It's a critical piece of information for any owner to be able to see and read.

37 Electrical System problem

Failure Date: 11/20/2020

Mcu failure while driving on the freeway. I was driving with autopilot on the freeway. The mcu failed and disengage the autopilot but there was no audio warning. Almost crashed into the wall of the hov lane.

38 Electrical System problem

Failure Date: 10/17/2020

Main screen computer (mcu)just shut down while driving. This is a very serious safety issue that Tesla already knew about and this is a long time issue.

39 Electrical System problem

Failure Date: 10/09/2020

Mcu issue and bubble screen.

40 Electrical System problem

Failure Date: 10/08/2020

The vehicle started taking longer to start up about a few months ago. Then the system needed to be rebooted on a regular basis to be functional. At one point the main screen that controls all the safety and visibility features of the vehicle stopped working and the vehicle would take up to 5 minutes to start up. After doing some research this is a common issue with Tesla's older than 2018 where they encounter an "emmc failure" of the mcu. The defect of the mcu was addressed when Tesla replaced the mcu in its vehicles in 2018. This should be treated as a recall due to the design flaw of the manufacturer. The mcu controls all the safety features of the vehicle and the rear view camera. Without the mcu it makes it extremely difficult to have the visibility needed to go in reverse.

41 Electrical System problem

Failure Date: 09/28/2020

Center consule went completely dark after mcu failed. Side mirrors could not be controlled and blinkers stopped working.

42 Electrical System problem

Failure Date: 09/11/2020

Touchscreen died completely affecting ability to drive vehicle. No ability to control defrost or air conditioning for windshield visibility. Turn signals produce no audible noise. No backup camera. No ability to change charge rate or reasonably identify when car will run out of charge and die on a long trip. I cannot tell of my battery fan is working to prevent overheating and fires. No ability to tell if airbags are functional or shut off. No ability to tell if miles driven are registered on odometer. No ability to turn on a tow mode if vehicle is disabled.

43 Electrical System problem

Failure Date: 09/07/2020

May 2020 while my car was still under warranty I continually had issues with the main screen. Issues were reported to Tesla who asserted it was the firmware. Tesla kept my car for over a week for repairs, then charged me $400 for new firmware. However within two months the issues began again, the screen going black and multiple errors. In August I was finally given another service appointment. This time they asserted it was the 12v battery (despite recently having that replaced in 2019). After replacing the 12v battery the problems with the mcu still persisted. It takes about 3wks to 1month to even get a service appointment. Now they are saying the issue is with the mcu which needs to be replaced. I do believe the issue was with the mcu all the time. I do believe Tesla either misdiagnosed or knowingly did not resolve the issue. Now I am being asked to pay $2500 not including tax and labor to replace the entire mcu for problems which were initially reported while the car was under warranty. Further, Tesla is now claiming they no longer have logs of diagnostics on my car when I requested to see the diagnostics that were previously run diagnosing my black screen althout the do agree my car has been continually brought in for a black screen and non-functioning system. Disabled screen functionality causes several other systems of the car not to work: regenerative braking disabled, autopilot disabled, driver and user settings, disabled, ac unit not functioning, stereo/radio capability disabled. Each day a different alarm or not would come on disabling another function while driving. Very dangerous and very unnerving, especially while transporting three young children. I have asked Tesla for diagnostics logs on my car and hoping to receive and submit them as support for this complaint.

44 Electrical System problem

Failure Date: 09/06/2020

The center console went dead, the vehicle could not be moved, would not even go into neutral, had to dragged out of the garage by the tow company and then shipped to the dedham, MA for repair. The issue was a failed emmc module and cost be about $600 in repairs.

45 Electrical System problem

Failure Date: 07/31/2020

While driving the car on July 31 at about 7pm, the center touchscreen went black and would not reset using Tesla instructions. Vehicle was parked. The a/c and climate controls were therefore stuck in the on position with no recourse. All other functions handled by touchscreen were inoperative. Tesla roadside assistance was called on morning of Aug 1 for oiptions, but reset protocols offerred did nothing to help solve the problem. Car taken in to Tesla service center on Aug 2, with inoperative mcu identified as the cause on Aug 3. Repair cost estimated to be about $1500. I then found out the repair was out of warranty only because Tesla had shortened the warranty by 2 years after I purchased the vehicle. If the warranty was as stated when the car was purchased, this repair would have been covered by Tesla. Sorry, no useful pics or docs appy at this point, as repair has not yet been made.

46 Electrical System problem

Failure Date: 07/27/2020

Main computer system died. All screens stopped functioning (including speedometer). Car wouldnt lock/unlock. Tesla said the mcu had to be replaced and they were going to charge me because it was 5 days out of warranty.

47 Electrical System problem

Failure Date: 07/24/2020

The touchscreen become less responsive the past few months, the power-up time becomes longer, the screen would freeze and would have to be rebooted, and on July 24th the mcu unit is a total failure. I couldn't even drive the car until Tesla mobile service comes out to cycle the power of 24v. The cost is $85 of diagnostics fee but he couldn't find anything besides that it is not responsive. After that I have to reschedule another visits which is not available until Aug 12th. I can drive now with black mcu but I can't control blinkers. My blinkers are always off. Very unsafe. This car has only 55k miles. It is right after the warranty expires. The mobile service and phone call with service shop in reno location both suggest me to replace to a new mcu and since it is out of pocket it makes sense to do a mcu upgrade instead. Total with part $2500 it would be around $3000.

48 Electrical System problem

Failure Date: 07/23/2020

Mcu-touchscreen emmc failure - mcu1 (version 1) unit in Tesla, including my 2016 Tesla Model X has an emmc chip that cause failures resulted in whole central screen going blank, freezes, and as result make car not-operational - no navigation, no climate control, no other controls of the vehicle, since it's all driven through central screen. Considering my car if just 3. 5 years old, this is really concerning and Tesla should address this technical flaw.

49 Electrical System problem

Failure Date: 07/22/2020

Sudden unexpected failure of mcu1-the main control touch screen of the car. Limiting access to key safety features such as back up camera and other vehicle controls. The vehicle had an unusual display behavior and took a prolonged time to wake up, then the center display failed to turn on at all. Manual reset attempts failed.

50 Electrical System problem

Failure Date: 07/18/2020

Mcu1 the main computer controlling the car crashes frequently and disables the car.

51 Electrical System problem

Failure Date: 07/17/2020

My screen goes black. This recovers over time when I reboot, but if I am checking mileage the screen goes black again. People who have the same car have told me that this is a known problem with the computer memory for this vehicle. This has happened when the car is stationary and moving on a city street. I am not able to get a service appointment until August 7, 2020.

52 Electrical System problem

Failure Date: 07/16/2020

The mcu in this 2016 Model X does not function properly. It will randomly crash and go completely black while the car is in use which stops all functionality of the hvac, radio/audio, navigation, etc. The car also contains a browser which doesn't work at all. The mcu is extremely laggy when it is working.

53 Electrical System problem

Failure Date: 07/15/2020

Tesla x model 2016 erratic behavior noticed. System will power up normal but some of the safety functions will not be available. Center screen will not render properly like it is frozen. Very frustrating. Yes Tesla is a low maintenance but if the computer modules / monitor that are heart of the car ( engine) there should be extended warranty on it. I am told that mcu unit needs to be replaced like saying your engine need replacement after 4 years. There should be standards on the computer hw devices on electric cars that are more robust and longer lasting. So much for low maintenance compare to cars with engines.

54 Electrical System problem

Failure Date: 07/13/2020

The mcu died, preventing use of the backup camera creating a hazard while backing up with low visibility.

55 Electrical System problem

Failure Date: 07/12/2020

The mcu screen on my Tesla went out after returning to the vehicle from it being parked. Screen would not turn on even after multiple reboots. Was able to drive the vehicle but lost all controls that the mcu screen controls, luckily it was a cooler day and I didn't need the ac but hvac is inaccessible when this goes out among other safety items. Prior to this there were times when the screen would be out and then come on after a few minutes. This is a known issue with Tesla model s/x vehicles built before April 2018. They seem to always fail outside warranty but this shouldn't be an issue and can cause harm because of what the mcu controls.

56 Electrical System problem

Failure Date: 07/06/2020

Chip failure in mcu caused turn signals to stop working at approx 65,000 miles. Known defect to Tesla and should be replaced as a recall as they changed the chip type for vehicles made in 2018 or newer due to this defect. The failure of this chip is a safety issue and they are currently charging owners $1500-$2500 to fix.

57 Electrical System problem

Failure Date: 07/06/2020

During charging, the car mcu screen went blank, and the car was not accessible or controllable. Vehicle was unresponsive until tow truck driver bypassed unit by jump starting the 12 volt battery. Limited control was regained. Car was drivable, but the rear doors were inoperative. I am not sure what other systems were inoperative. I am concerned about this happening during driving or getting stranded in a remote place.

58 Electrical System problem

Failure Date: 07/03/2020

Mcu (media control unit) failed on multiple occasions, I was unable to control ac/radio/autopilot system/ or navigation. Also both turn signal were in-operational. Tesla service center refuses to replace the mcu or fix it. Vehicle was in motion, on highway at a speed of about 70 mph.

59 Electrical System problem

Failure Date: 07/03/2020

Center screen (mcu) dies/freezes up while driving and must try to reset all the time. Tesla refuses to accept resposibility and replace with new mcu under warranty.

60 Electrical System problem

Failure Date: 06/20/2020

Vehicle was stationary, long start up times before I can initiate drive as shown in picture just a t logo for about 10-20 seconds. Also stationary and in motion can not pull up some items like vehicle charging or features just get a blank white screen as shown. All have to do since it is on mcu1.

61 Electrical System problem

Failure Date: 06/09/2020

The mcu (the car's center screen) would not turn on. The center screen controls everything in the car including all the updates. Since the center screen didn't work, and update was not able to pass through, and it essentially made the car not drivable. The car was in the turn off mode and would not turn on.

62 Electrical System problem

Failure Date: 06/01/2020

My vehicle's center display (mcu) is starting to show signs of failure on account of a flawed design that depends on an emmc memory component that is known to fail catastrophically after several thousand write cycles, causing loss of critical adas and rear view camera functions, hvac controls, and other basic vehicle functions. Now, I am facing the prospect of having to pay Tesla thousands of dollars to replace the entire mcu in my just-out-of-warranty vehicle. Tesla has tacitly acknowledged the safety implications of their original design by modifying it to use a more robust memory component in 2018, and they should be made to recall pre-2018 models to ensure that nobody else has to endure what I and many hundreds of others have experienced.

63 Electrical System problem

Failure Date: 05/26/2020

Failure and replacement of mcu touchscreen panel in my Model X. Could not safely operate the vehicle because I was unable to extend side mirrors, use back-up camera, turn on/off ac or heating or use navigation. Other safety features requiring using or seeing the touchscreen panel were not accessible. Vehicle 7 weeks out of 3 year warranty but only had 20,039 miles on it. Tesla said I needed to play for a new touchscreen panel. After a strenuous discussion Tesla agreed to discount the repair by 50%. I still had to pay $841. 63 for something I felt was a safety issue. Luckily the car was parked and at home at the time of the failure. It could have been catastrophic if it happen while driving. I felt the touchscreen panel failure was caused by a manufacturing defect and should have been replaced at no charge. Also, if Tesla found it had a history of these panels failing, they should have done a recall. In no way should such a critical component fail in a vehicle that is 3 years, 7 weeks old with just over 20,000 miles on it.

64 Electrical System problem

Failure Date: 05/01/2020

The main screen failed. This in turn caused other systems to not work correctly. Examples include rear view camera, turn signals, infotainment system which includes maps, navigation, music and the ability to change any settings on the car. The car was stationary when the mcu stopped working.

65 Electrical System problem

Failure Date: 04/15/2020

Car was park for a few days. Got in the car and the main control screen did not come on. I restarted the car a few times and noting, car was able to be driven but whit no access to ac, radio, back up camera and most important turn signals, since all the controls are in the center screen. I contacted Tesla and was able to drive it, cautiously since the review camera acts as a blind sport monitor for me. Tesla replace the center computer under extend warranty, witch has a $200 deductible.

66 Electrical System problem

Failure Date: 03/15/2020

Main display stops functioning, causing loss of several necessary and safety functions including but not limited vehicle control, climate, navigation and vehicle status. This is a known problem for Tesla models s and x sold before 2018.

67 Electrical System problem

Failure Date: 02/10/2020

While highway driving the main mcu froze due to a manufacturer known memory corruption defect and would not reboot. This defect failure impacts access and control of the following safety features, turn signals, emergency brake, emergency battery disconnect, fog lights (front and rear), auto high beams, rear pedestrian camera, suspension (inability to disable auto leveling for tire changing or towing), traction control slip start, side mirror adjustments. Battery safety limits for acceleration and regen based on environmental temperature safety limits are also disabled. This mcu failure also prevents refueling (l3 dcfc stations). As well as the hvac system from being turned off while parked. Which continued to drain the primary battery for several hours. The odometer is also not available, as well as the hands free bluetooth feature and other non safety features. The initial incident occurred under warranty. The manufacturer switched to a backup memory partition to repair or workaround the defect issue temporarily. Within 3 months, less than 1,000 miles later, the backup partition also became permanently corrupted and required a complete replacement of the unit, out of warranty.

68 Electrical System problem

Failure Date: 11/18/2019

2016 Tesla Model X. Consumer writes in regards to NHTSA safety recall 20v-062 and 20v-710. The consumer stated the dealer would not honor the recall stating the vehicle was not experiencing the failure. The consumer stated the screen would black out randomly and the steering assist did not function properly. The vehicle was involved in an accident due to the failure. The vehicle had trim separation that would leak water that the dealer would not repair.

69 Electrical System problem

Failure Date: 11/08/2019

I have had problems with my Tesla 1- doors repeatedly malfunctioning (stationary and driving) 2- the accelerator was malfunctioning, city streets and freeways 3- computer shot down while driving and screen went blank.
