This complaint is about Tesla's first generation media control unit (mcu). The mcu is the brains of the car and control the big center screen that the Tesla Model S is known for. When it failed not only did I lose the ability to use this big screen but I also lost key safety items signals, backup camera, cruise control, automatic breaking, and auto pilot. All the sound features are also disengaged as well and this was evident in the lack of sound for the turn signal as well as the lack of sound for the alert if your seatbelt is undone. Specifically in regards to the turn signal for example if you put the turn signal down to as if you are turning left the nob will lock into the down position leading you to believe your turn signal is working but unless you are outside the car you have no awareness to the fact that the signals are not blinking. In addition to this my car lost its control of the air condition and any millage tracking features were lost. The mcu completely failed on me 3 times. The first two times it came back after a few hours and the third time it never came back (was driven to the service center after 3 days and it still hadn't come back). The failed mcu allows you to continue to drive the car and you have no awareness to the safety features that are disengaged. Also, all the sensors are disengaged to me the user which stops the car from alerting me to objects ahead, behind and to either side of me. There are endless articles about the first generation mcu failures. The chips inside these cars are known to fail after a certain numbers of cycles and Tesla has yet to address this known issues leaving the consumer to fend for themselves. Please investigate these issues and hold Tesla accountable.
Tesla Model S main screen died. It's a known issue on early Model S with mcdu version 1. A chip on the circuit board can only handle xxx amounts of writes, or write overs, then gives up. Screen goes blank. Most Model S car functions are controlled on the main screen. My screen failed while driving. Unable to set or control charging. Unable to turn off a/c. Unable to hear turn signals. Unable to turn on or control headlights. Unable to close sunroof. Unable to change suspension settings. Unable to change steering settings. Unable to change lighting on the dash. Most features in the Model S are not available.
The mcu1 (infotainment) center failed completely, rendering the vehicle inoperative!.
Tesla media control unit ("mcu") is no longer operable (screen turns black and loses all functions). The Tesla mcu is basically the car's central control system that allows you to adjust the headlights, the steering wheel resistance, the vehicle charging controls, the vehicle suspensions. . . Etc. The screen turned black, my turn lights are disabled (as shown in image, lights will no longer blink), my headlights are disabled, my airbag functions can no longer be switched to off when needed, the moon roof cannot be opened, the ac system along with defrost/cooling functions are all disabled and inaccessible. The vehicle dashboard displays "please wait while vehicle system powers up" for anywhere between 1 minutes to 4. 5 minutes. The vehicle is not operable during the system power up when I enter the car. This issue appears to be connected with the mcu failure and have persisted and worsened in the months leading up to the complete failure on 7/16. I would have to sit in vehicle for 1-4 minutes, unable to drive the car because it is loading up. This shows that the mcu is extremely essential to the vehicle, and not merely a media unit as they have tried to convince with the name. It appears that the mcu fails after a number of years/usage due to the old chip that rewrites over repeatedly. The mcu is pre-installed to fail in all vehicles produced prior to 2018 in the model x and s. Basically this system will fail in every car at uses the old mcu1, and doesn't apply to vehicles after 2018 since the switch to mcu2. I reached out to Tesla service center by phone (unable to access the Tesla app due to the inability for app and vehicle to communicate), and they quoted a replacement of the same mcu (but with an upgraded chip) at the price of $1201, with a 3 week waiting period. The car is not inoperable for the next 3 weeks due to the lost of essential and safety functions.
Mcu failure Model S 2015 82,000 large screen failed. Disabling lots of functionality including ac with over 100 outside air temp. Child in car. No turn signals, lights, navigation or ability to charge. Vehicle was stationary parked at home. No visible warning of failure before hand.
Intermittent failure of the mcu1 ome, causing intermittent main screen blackout, turn signal malfunction, a/c disabling. Rebooting required mcu to be upgraded/replaced out of warranty.
The center screen of my Tesla stopped working when I started the car one day (car was parked), resulting in a loss of the backup camera and access to many driver settings, such as regenerative braking, automatic lights, etc. Rebooting the unit did not help, and the car would not shut off once the issue occurred.
The mcu failed while we were traveling, which basically locked the climate control, access to suspension, speed control, autopilot, navigation, radio, turn signals, and back up camera.
Mcu on Tesla crashed again. Last year it was replaced, and this year crashed again. Tesla keeps postponing repair. Saying they are too busy. With the mcu crashed, turn signal does not work and makes car not driveable. I understand you all are investigating this issue? the date identified below is the second time. This happened last year as well.
The mcu that operates the car failed.
Complete failure of mcu when starting the car after only 31k miles, causing blackout of al screens, driver information, controls, etc. Tesla had me drive it to the service center in that condition and charged $1,462 to replace without any indication that it is a known design problem. (note incident date is approximate. ).
Well docmented failure of a memory chip that has been docuteted to fail after a certin amount of read/write cycles, Tesla has been well aware of this fault for years and has done nothing to address the issues leaving owners sometime stranded or reducled vehilce functionalty. Teslas respnose has been to replace the faulty system with a refurbish unit that will have the same issue in the futiure and charging the customer between 1500-2000 to replace.
Noticed that the display on my Tesla Model S not working as I pulled my car out of the driveway. Tried rebooting but screen did not come up. Was able to drive the vehicle to Tesla service center though it felt a little unsafe as many of the controls are on the display. After diagnosis, Tesla service advisor told me that the mcu for my Model S has failed and needs to be replaced. I paid ~$2000 for a new mcu. After reading recent article on similar failures reported by other Tesla Model S owners, decided to report this as failure of the display unit while driving can be a safety risk.
Hi, I have severals issue with the car which are known issues for the manufacturer and for which service center says "yes it's an known problem on all these 2015 Model S car" but you have to pay to get it repaired because the car is over 4 years old and more than 100 000km, so not under warranty anymore. Theses issues are : * two doors handles 1042845-00-b (one I paid for being repaired 60. 83) one actually broken so right front door can't be opened from outside. Nearly all customers from Model S from 2012 to 2015 have this problem for doors. In my case two times were when childs closed the door from outside a bit stronger, so it can happen anytime you close a Model S door ftom this generation. The part 1042845-00-a has been versioned 1042845-00-b (the "a" is less resistant). * two windows can't easily be closes (the two on right side) even more when temprature is more tha 20c, anti-pinch system don't work well so the window reoppen. So sometimes you let the car with windows opened with rain risk if you don't check it. In this second case, service center says this is also a known problem and say they can change whole part with payment ! * more important is computer issue with emmc failure where 8gb nand memory is getting by the time with read/write error because of use cycles, making so many issues on computer : screen hangs (nned reboot), autopilot issue, entertainement media loading or use issue, maps fot gps slow or locked, long time before starting car (more than 2 minutes sometimes) until the time memory is definitly deas so the car remains unusable. In this case again, this is an problem from origin and should be replaced for free even after the 4 years warranty because problem comes with time. Tesla asked 2500 for whole replacement with computer, screens, 4g chip. . . Whereas they don't built it correctly ! * wheel broken no airbag, horn, commands. . .
Random failure including loss of controls using mcu1. Frequent re-setting / re-booting required to operate the vehicle using mcu 1 controls.
I put the car in reverse and the screen was black. All the controls were stuck. . . Fan/ac. . . Back up camera did not work. My turning signals did not work. Tesla service center was closed so all the ac did not turn off and drained the battery all the way to 0 range. Took a lot of trouble to get to the service center the next day. They concluded the mcu was dead and had to be replaced claiming that it was wear and tear. Without any warning, the mcu crashed and comprised safety of the car with the turning signals, suspension and rear back up camera not working amongst others since the mcu controls everything. We believed Tesla knew of the problem and put it on owners to replace at their own expense if out of warranty even though it seems to happen around when the warranty ends. We have 2 Teslas and both the mcus died a little over 50k. It should have been a safety recall and the mcus replaced at no cost. Terrible business practice and service for such expensive cars. We are very disappointed in Tesla.
Touch screen failure. Screen went blank Jan 3rd 2019 still under warranty. Was able to reset after many tries. Parked car went to winter home. Returned April 16th same problem. Working with Tesla through out problem. Finally Tesla said bring the car in. Now out of warranty so had to replace mcu $2250. 00.
When I purchased my car less than a year ago, it came with a 50,000 mile, 4 year "new car" warranty although it was a used car with approx 25k miles. Within 6 months, an update came out over the air and changed my software, and ultimately lead to a range loss of approx 40 miles and an increase in charging time by approx 3x because Tesla, admittedly through their service texts, has limited the charging on my car to "preserve battery life. " this is akin to selling me a 8 cylinder car, and limiting it to 6 to not have to change engine. The car has become almost unusable as it takes 3 hours to charge when it used to take 45 minutes. The car was able to get a full 116 kw for an extended period of time when the battery was below 15%-30% and the charging would gradually (over 45 minutes) drop to about 40kw. Now it starts at around 110 kw and quickly (within 5 minutes) drops to below 80kw. It tapers off and charges around an average of 35-40 kw. Tesla should be changing the batteries as they knowingly are doing this to stop the battery from over heating and starting on fire. This is a hazard and Tesla, instead of replacing the part with a warranty, limits the performance of the vehicle without telling the owner.
