the vehicle's center display is malfunctioning in which we experience a persistent blank center display that does not recover after restarting the touchscreen, loss of certain functionalities occurs. I took it into the manufacturer they said that the "code" issue was fixed, but the problem persists.
2014 Tesla Model S electrical complaints
Page 3 of 6: complaints 41 to 70 of 134, newest first, as owners wrote them.
I have had repeated failures related to the main display (mcu) on my tesla model s, included failure to start when the car was powered up, "crashing" during driving, "locking" or "freezing" of entertainment screens onto the display that remain even while driving, and slow response to instructions. It was initially replaced under warranty with a remanufactured mcu1 unit in february 2020. The car continued to have problems and I scheduled service two more times during 2020 and tesla refused to replace the hardware each time. They said they "cleared the memory" and "reset the firmware". This solved the immediate problems but the problems returned, sometimes within days. I have heard anecdotally that tesla reduced data logging to try and preserve the life of these units; ironically, I believe, this results in tesla saying there was nothing logged and thus refusing to replace the hardware. In january of 2021, out of concern for the safety of my car, I paid $2500 to upgrade from mcu1 to mcu2 based on staff saying that would solve my problems. It has not. In the 10 days since the upgrade, it has "crashed" 2 more times while driving and "froze" part of the display another time while driving. I have lost unexpectedly : navigation in the middle of a complicated interchange, the rear camera needed to reverse safely, many controls including lights, heating, AC, and charging. With the mcu2 crash, I also lost the dashboard display (e.g. Speed). Finally, the implementation of the display of the rear camera in mcu2 (the rear camera is the same) is bad - at night the display is so dark it is almost useless. This is a step backwards. I have been repeatedly told an impending firmware update will fix the problems. I have received several updates, but none fixed the problems. The attached photo is the most recent crash of the new mcu2.
My daughter was driving the car. The touch screen suddenly frozen during driving around 12:35 p.m. Dec. 28 2020. (the exact date could not remembered, but I have file with tesla on the day it happened). The wind shield got frog up very fast. I could not turn on defrost and almost have a collision due to poor visibility. I had to use paper to clean the moister of the wind shield and so the visibility was good enough for my daughter to drive the car back home safely.
The center info screen goes black and you lose the backup camera , HVAC controls, radio, and all other functions to the car. Happens randomly. Creates a safety issue and is known problem with this tesla model
Manufactures known defective mcu 1 defective memory housed in daughterboard and screens leaking adhesive in the driver's instrument cluster and 17" screen on mcu, adhesive dripping down onto cabin area .
My touchscreen went out (all black) a year ago. The replacement was a refurbished one. It took two weeks. When I asked if it was improved, I was told it's the same but has a new two-year warrantee. Now a year later, it is starting to "act up" like the first. Add to that, the last three road trips with it each had something break on it or needed attention. Air conditioning compressor 800 miles from home in august 2019. Driver's door handle extending gear. And 12v battery, only to learn weeks later that it was "fixed" with a software upgrade. What good is an extended warrantee, if you breakdown on a trip? The car is unreliable. I'm going to get rid of it. Just add my complaint to the list of unhappy owners.
Total loss of display in the middle console keeps going black, total loss of turn signals, suspension control, heater controls, de fog and de ice, no rear camera, no cruise control, high low beams,no ability to use fog lamps. Plus many more things too numerous to list. I took it to service dept and they did a temp fix for $150 but told me it will go out again and it did the very next morning. Something to do what's called the mcu memory failing. Its gone dark on several occasions many different dates. There is no way to know when it will do it again. Makes the vehicle in my estimation more likely to get into a crash
The entire screen went black and it started showing the backup camera. I couldn't fix it even by restarting it. Notifications included- center display unavailable, it also affected the turn signal while driving and cruise control. Other safety features of the vehicle were also unavailable.
The touch screen freezes, blacks out, and becomes unresponsive. This is due to a well known issue with the mcu. Tesla has issued an extended warranty to 100,000 miles but my car has 106,000 miles so is ineligible and the repair is thousand of dollars. This issue started before the car had 100,000 miles but tesla didn't offer the repair until november, 2020 by which time the vehicle exceeded 100,000 miles. Without the touch screen most vehicle controls cannot be accessed which is a major safety issue. Issue started on 5/10/2019 and continue to occur almost daily.
1. Replaced mcu, at my cost. Several weeks later a lesser expensive fix was announced. Several weeks after that announcement tesla notified me that I may fall under an extended warranty for the replacement. It turns out that because my vehicle was over 100,000 miles at the time of replacement (114,000) it does not qualify for the extended warranty. I purchase the car as certified pre-owned from tesla with 22,000 miles. My ownership miles was under 100,000 miles at the time of the replacement. Considering the failures of the mcu in older model vehicles, and a known problem, I would think I would be covered. 2. Door handles - all 4 door handles have been replaced at least twice since ownership. Again, a known issue in the design. All but one replacement were completed at no charge. The last replacement was done after 14 months from the previous replacement. Tesla only warranties for 1 year since replacement. I don't understand why something that is a known failure would be my responsiblity. 3. Tpms sensors - again, a known issue that the original sensors were a bad design. Tesla will only replace with the upgraded version, at my cost of around $1,000! I am forced to find a non-tesla repair facility to replace the sensors, at a lower cost. Again, where is the accountability on tesla to stand behind known issues.
The instrument control screen is failing as the glass is separating from the glass and unable to view icons on the panel. Telsa is not going to replace unless 1500 is paid for replacement with updated screen that does not separate from the glass. Some people are reporting it as bubbling or impression of water marks behind the glass but it is the glue failing. This is a known issue. For the wheel issue, the TPMS system is failing and telsa will not replace unless 1k is paid to "upgrade" the system.
My suspension is constantly making sounds and after taking to tesla it was 3rd time it has been determined that the fore link, control arm and bushings have gone out. I repaired it and now seems the problem is back
My main screen went black, and I can no longer use the back up camera, temperature control, charging levels, and the 12 v battery is now stating a fault. This is similar to other multiple complaints under action number pe20010.
Tl* the contact owns a 2014 tesla model s. The contact's wife was driving on the highway when the media control unit display went blank. The vehicle was pulled over to side of the roadway. The contact went to the scene, retrieved the vehicle, and drove to the residence. The display screen independently returned to normal operation. The contact called tesla (135 us highway 22, springfield, nj 07081, (973) 921-0925) and the vehicle taken to the dealer to be diagnosed. After a week of testing, the contact was informed that the media control unit needed to be replaced at a cost of $3,500. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 115,000.
Tesla cpu failure is causing car to have issues. Bluetooth will not connect, car will not unlock, lights do not work- either are stuck on or off, blinkers do not work, back up camera does not work, air conditioning is stuck on which drains battery, cannot charge the car when it is not responding as charging port will not unlock. Car has essentially turned into a brick with <60,000 miles. Very disappointed in tesla. These happen both when vehicle is moving and stationary.
Touch screen interface to many controls does not power up for past 3 months since early june 2020. Turn signal does not operate, air conditioning controls not available, car charge rate is defaulted to 8 amps only - think this prevents road trips as charging would take full day to charge, waiting for repair.from tesla for 3 months and finally have scheduled repair after multiple attempts to push this.
Tl* the contact owns a 2014 tesla model s. The contact stated that the monitor for the back-up camera was inoperable. The contact took the vehicle the dealer tesla (28721 canwood street, bldg-a, agoura hills, ca 91301, 816‑540‑4729 and was informed that the mcuv1 module was defective. The hardware was used to update the system but was inoperable. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 70,000.
Failure of touchscreen. Dashboard display at -5 brightness, could not see the information. No turn signals and no reverse camera. Loss of control to air/heating, sunroof, music, garage door control. Tesla remote diagnostics team determined the mcu had an internal fault and would need to be replaced.
The touchscreen would become less responsive, the power-up time becomes longer, the screen would freeze and would have to be rebooted, or even total failure of the mcu unit and one day complete blackout of screen. This happens when its stationary and driving both
My infotainment (center lcd panel) shut off without warning and could not be restarted while driving. This sudden failure took my attention away from the road and repeatedly attempting to restart the screen was also a hazard forcing me to pull to the side of the road but was still unable to restart the infotainment center. With the infotainment system down, the majority of the features in the vehicle are cut off from me. I later read that this is a common problem affecting teslas built between 2013 and 2018.
Mcu touchscreen failed. Vehicle was stationary. Turn signals and other functions quit working.
Total main computer failure (mcu) - many safety features were unaccessible and not available including but not limited to turn signals and hazard lights stop working, the settings for autopilot and driving are gone, the suspension settings, the ability to turn on headlights manually, ability to manually lock and unlock the vehicle, navigation, A/C, sunroof controls, etc.
My automobile has become unresponsive. When I attempt to start it, the message "systems are powering up" appears but nothing happens. This has happened on several occasions and now 2 days in a row and am unable to drive the car as it does not allow me to. I have waited over 15 minutes with still no response. It had remained parked for 3 days before trying to operate it. I am unable to reset the power on the car since the media control screen stays black. The tesla app will not connect to the car. The windows, lights, door locks still operate, but I am unable to shift the car into drive to get to a service center. I am told it will be $195 to diagnose. I have 102,132 miles. The issues started occurring approximately 50k miles after I purchased it. In february of this year, I replaced the 12v battery after a warning indication appeared and told me I needed to. At this time, there are no indications.
Tesla mcu failing. No rear view camera. No turn signals and all display items on the center screen unavailable including climate control, when the mcu - media control unit freezes or goes black. I was having symptoms of imminent failure and I had the emmc chip replaced by a 3d party to insure I wouldn't get stuck.
Ms1 broken, needed to replace
Media control unit mcu failure. No aeb (advanced emergency braking) no controlling suspension height no manual control of headlight lights no blinker sounds steering mode defaults to some setting (e.g. If I have it set to sport, during reboot of mcu is changes to standard or comfort, not sure but I can feel the steering wheel take less effort to turn than my normal sport mode) no HVAC (heat, cool, vent) no defrosters no seat heaters no steering wheel heaters no radio/streaming no app connectivity to control the car no ability to see the car charge status from app
Media control unit(mcu) failed due to design flaw of memory being overwritten until it hits a limit. Once the limit is hit, the mcu no longer works. The mcu controls the back up camera and turn signals. Both no longer work and I am not able to view the back up camera or signal lane changes or turns while driving.
Drove out of town and parked the vehicle in driveway for about 5 hours, when I retuned to drive it back (10 pm) center touch screen was blank. I noticed that there was loss of function of nearly everything in the vehicle. I could still drive it but with ability to use turn signal lights, or headlights (very dangerous drive at night). Steering wheel buttons, AC, audio, phone bluetooth, and all controls of the vehicle were completely lost. It was 90 degrees outside that night and had to drive without AC, I could not make or receive phone calls due to black screen, sun roof could not be opened. Basically the vehicle became a bare basic vehicle without any of the safety features or even the basic feature such as signal lights. I am not sure if there was an emergency if airbags would have responded either! The car felt just too scary to drive!! Odometer would not count the miles too, odometer is lost and app shows the mileage from yesterday (even though I drove 50 miles on it to get home), I even notice battery started draining faster while I was driving it back home.. Performed soft and hard reset per tesla website recommendations without ability to restore any of the functions or make the center screen display anything. I attempted connecting through the tesla app, and although I was able to connect to the vehicle, the car would not respond to app for any of the controls, climate etc. Contacted tesla next morning and they stated that since vehicle is out of warranty that I will have to bring it to service center or tow it if unsafe to drive and pay for repair to restore its functions. The small dash screen still was working, but continues to display a message to "wait while vehicle systems power up". It is completely an unsafe car at this time on every level
Screen blacked out and I lost signals and control
Mcu 1 failure in an older model s. Tesla recognized the issue and is now installing a better mcu. However, warranty repairs are being done with refurbished mcu 1 components.
