While driving main screen turns off - reboots about 5-10 minutes off- while off- turn signals are not audible inside car all other safety parameters are not accessible: collision avoidance, brake assistance, this has occurred multiple times - I must take a picture while occurring which happens while driving. Tesla has full access to logs. Diagnostics by tesla representative tells me that my memory chip is within parameters and thus not eligible to be replaced. Although I must continue to experience the reboots that shutdown most of its features while it occurs. Not to mention my daily occurrences: - charging system adjustment panel does not draw on screen properly; which causes incorrect selection of amount of charge needed. Center arrow which is supposed to show doesn't until after selected.
Car randomly freezes. Many navigation functions such as turn signals will stop working. Nearly caused a collision. Replaced mcu per tesla's advice. Issues continue. The last written statement from tesla is "known characteristic of current firmware." unwilling to address or fix issues at any cost.
My guess is the mcu or the computer chip of the car stopped working. I read there is an investigation on tesla for this issue with model s. Every last few software updates the car has been getting worse and now the electrical stopped working completely. I can use my blinkers even! The car drives and charges, but that is about it. 40k miles total and build 2015.
I believe a complete failure of the embedded multimediacard. No touch screen use, no camera, no audible sounds for turn signal or warnings, no control over lights or door locks. Earlier in the year, I noticed non responsive request to start up the car, undrivable for 45 seconds, now it is up to a few minutes upon entering the car, which is a safety issue. Especially when combined with not being able to lock the doors with the lcd. I believe this is the screen issue that tesla is offering repairs now, but I have tried to make an appointment, and the earliest one is two weeks out, which I have made.
The mcu in this car went black several occasion while driving. I lost all controls of lightings and wiper. On several occasions....the car shut down and I have to coast to the aide of the higjway
Infotainment system has stopped working, along with important safety features like lighting, blinkers, cruise control, climate.
Head and tail lights turned off while driving on highway and would not turn back on. Neither high nor low beams would engage! A driver behind me saw what happened and turned on his high beams to guide me approx 1 mile to a safe stopping place. Once stopped, I experimented: hazard lights would turn on. No other lights turned on. I rebooted both the "mcu" (central 15" screen) and "ic" (instrument cluster) per earlier instructions from tesla in case of automation failure in the car. The mcu took an extremely long time to restart and displayed screen corruption, problems which in the past had LED tesla to replace that component of this vehicle under warranty. When the mcu did start up, the instrument cluster displayed "driver assistance features disabled". I attempted to use tesla's voice-activated "report" function to get help from tesla, but this resulted in a message stating that "the microphone is being calibrated". This entire time, the head and tail lights remained off and would not turn on. Finally I used the mcu to access the lighting settings of the car. I observed that the "exterior lights" setting displayed "auto". However, it was 6:40pm and almost completely dark and the lights had been on previous to suddenly turning off. Also, with the "auto" setting, the high beams should still engage when pulling the left stalk - but this did not work. I next used this same screen to turn on the front fog lights. This worked! I then turned off the fog lights, changed the "exterior lights" setting to off then back to "auto" and all exterior lights (head and tail) finally came back on! It is my opinion, based on over 20 years in embedded software development, that the mcu's "exterior lights" setting had become corrupted and forced all vehicle lights off while I drove in darkness at 45mph. I could have died. Make tesla fix this before someone dies!
The media control unit on the car failed and needs to be replaced. In addition to all controls operated by the touch screen, including the back-up camera, the car's blinkers do not work.
The main center screen computer began degrading in performance over time (causing more driver attention to be diverted away from driving to deal with functions it controls, as it was laggy and not very responsive). Then, one day, I got into the car to go somewhere and wasn't able to boot the main computer/screen at all. In addition to everything it controls no longer being accessible or working (e.g. Climate control, manual headlights, dome lights, anti-theft alarm, power steering strength, suspension height, etc.), I also found that I no longer had working turn signals and had to use out-the-window hand signals when I drove to the service center for repair.
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.
The tesla's large screen quit working. These are controls that power off the vehicle, turn the defrosters off and on along with the climate control. Control steering modes. Control back up camera, control lights. From the reading I have done it is called the mcu. It partially went out while I was driving, it came back on and then it died while I was working and I found out about it when I started the car after work.
Turn signals all failed, rear camera failed, touchscreen interface failed
The mcu (version 1) of my car stopped functioning while parked and needed to be replaced. This is a known issue (emmc failure). The car was still operational however the following safety issues resulted from the mcu malfunction: - turn signals and audible chime both beame nonoperational - reverse camera beame nonoperational - high beam headlights beame nonoperational - lane departure warning may hae become nonoperational - climate control stuck at one level - instrument cluster lighting setting became unable to be changed additional issues resulting from the mcu1 failure: - all systems and settings accessed through the center console screen beame unaccessible - navigation system beame nonoperational - audio controls beame nonoperational - auto-pilot (lane assist) beame nonoperational - alternating current (AC) charging speed reduced to 2kw - remote access via smartphone beame nonoperational
The emmc chip in the media control unit failed resulting in the large touch screen no longer working. I lost control of the turn signals, climate control, rear view camera, charging, navigation, and audio. It is the same problem described in your pe 20-010 investigation document.
My media control unit failed in the vehicle making it unsafe to operate as the turn signals, defrost, headlight controls, among many other features of the vehicle were no longer accessible or functioning.
After we returned from our summer home, I tried to drive the tesla. The main screen did not light up but I figured that a normal reset would fix the problem. As I drove, I attempted a reset but the screen remained black. I also learned that the turn signals would not work including the cruise control, windsheild wipers and headlight high beams. Worried about other problems, I returned home and have not driven the car since. Over the summer there had been several updates to the cars firmware and I was looking forward to the improvements. Prior to that. We were driving with other members of the family, all with the tesla app on their phones. The car went into "limp home" mode on I-95 and would not respond to numerous attempts to remedy the problem. The seat heaters would turn on and off, the doors would unlock and the entire car seemed to have a mind of it's own. I asked everyone to turn off their phones and the problem disappeared. Tesla service said they'd never heard of such a thing.
Middle screen went out putting the car in 'limp mode' happened in the middle of the night and we didn't have headlights or turn signals! Happened while driving about two hours from home when we tried putting a route in the touch screen after setting the automatic update for 2 am the following morning. The car has 101k miles the warranty expired at 100k miles. We notified tesla of the problems we've been having with our screen freezing and rear view camera randomly not working while it was under warranty but the techs said 'everything is fine and it must have been a fluke' now that the car is out of warranty the now suddenly know the problem and a solution! This defect is scary and left us stranded and unable to navigate to a safe area off the highway in the middle of the night without headlights!!! Why would they jeopardize safety over money!
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.
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.
The vehicle had computer issues during oct10-feb1. Loss of connectivity, reboots occur while driving. No speedometer. No turn signal indicators, no parking brake ability, I parked vehicle feb1 for safety reasons. Attempted to get service. Vehicle by april[15] had gone from intermittent to permanent. No visibility of computer screen.no functions. No high headlights, just low headlights, no crash imminent buzzer, no autobraking. Drive&reverse only, steering different, slightly stiffer, no hands free phone & no GPS ability. Easy to get lost or confused as to where to turn or whether to turn or go forward. Arm out windows for turning, reduced speed controls. No lane departure buzzer. Changing lane refusal w adjacent car present in lane inoperative. Comp. Not covered by warranty, while under warranty, the repair was declined, stating 'it must be completely dead before it can be replaced under warranty' by apr15 comp. Was completely dead but I had declared warranty inadequate upon first refusal to cover it, july, no parts available, so many weeks of waiting. Dealer unable to find an upgrade part to sell to me. Waiting for a $2500 install of a new part that I am willing to pay for but cannot procure quickly enuf, no matter what. Driving without control of headlights or without turn signals has been curtailed but for emergency food procurement. Doctor visits, mask&glove replacements for the covid situation requires those. I have been lucky I guess that this has happened permanently at home & only a few sudden times temporarily on the road. The failure was intermittent, denied replacement requests & finally failrd entirely, now all must wait while unable to safely drive much of anywhere. Car not sale-able, nor does it cease dropping in price every month while I await a fix. Rental is expensive. Insurance gave me first 30 days, those over now. Susp. Insur. Thank you.
The touchscreen in my 2015 model s has completely failed. I've attempted all of the resets that tesla recommends to restart the system to no avail. The car is nearly useless, none of the electrical features of the vehicle work, including heating/air conditioning, charging features, audio or turn signals. The car worked fine yesterday, today the screen was just gone.
The 12v battery on our 2015 tesla model s started failing last november. We were assured that tesla that it would be safe to drive until they could replace the battery (which took about 2 months). We've come to understand that this is far from accurate. After that, our mcu (the main computer in the car) failed. This is apparently a well known problem that tesla refuses to fix. When they replaced the mcu we immediately started having issues: 1. The emergency flashers did not work. 2. The computer logs were not available to tesla to diagnose issues or recover our car if it was stollen. 3. The fog lights stopped working 4. Glove box would not open 5. Screen now has noticeable flicker 6. Car now has charging problems. The issues with the emergency flashers, fog lights, and glove box were able to fixed by a different service center the same day (although I had to drive approx. 30 miles to get to a different service center). The logging issue took about a month or two to fix. The screen flicker and charging issues where the car randomly switches to a different charging level while driving or charging without any error messages, is on-going. I've been back to tesla over a dozen times, and they ike to charge $100 every visit "under warranty."
Loss of turn signal noise, headlight control, rearview camera, climate control, seat memory, garage door opening capability, navigation, emergency braking, and difficulty charging the car. This occurred gradually over the course of a couple of days and has left the vehicle inoperable without headlight control, auditory warnings, and rearview camera. This is caused by a failed emmc chip on the mcu in the car. It is a well known problem and not covered outside of warranty, despite it being guaranteed to fail sometime between 4 years and 5 years of age. (warranty up after 4)
The main screen, mcu, on my tesla model s, 2015 70d began rebooting during driving. On saturday, july 4th, 2020, the car would not start at all. Tesla customer service coached me on getting the car to work without the main screen, however it is not safe. The brake lights, signal lights, rear camera do not work, verified by my spouse. Further, most of the other controls, e.g. De-fog, air conditioning, roof, etc, do not work. The re-booting of the screen, where it would blank out without warning, and eventually come back later, occurred while the car was in motion -- very distracting. At this point, the main display, or mcu, is "bricked" -- it won't display anything at all, so that has happened when the car is stationary.
My tesla mcu1 screen/memory failed and had to be replaced at my expense. $1600. When that happens, turn signals, climate control, and wipers are inoperative, making the vehicle unsafe to drive.
The infotainment computer mcu1 is known to fail prematurely due to software issues caused and not fixed in a timely manner by tesla. Basically the limited write cycles of flash memory are exhausted due to excessive logging up to a certain software version. My car shows the early warning signs including black screens on entering (car is not movable for several minutes) and reboots during driving. Full mcu failure is known to cause indicator lights to fail, automatic emergency braking to not engage, disabled fast charging and no accurate charge indicator (so risk of getting stranded), heating/ventilation stuck to most recent setting (no defrost), audio fragments being stuck on arbitrary volume, air suspension is stuck to possibly unsuitable settings and the speedometer is reverting to MPH instead of km/h without notification. If pin to drive is used, the car can no longer be unlocked and moved. Tesla does not acknowledge this problem and charges for full repair cost outside of warranty / drags cases of impending mcu failure until the car is out of warranty. Mcu1 can be replaced with mcu2 according to a tesla infotainment website; however only mcu1 replacements for the oldest cars (ap1 sensor level) are available to date despite announcement these would be ready in april 2020. Newer cars with longer remaining life can be upgraded upon invitation by tesla.
My touchscreen has failed completely and I am unable to use my blinkers or control my lights this is a big safety concern and tesla has stated that it's normal for computer systems to fail.
Center console display and computer failed as described in the federal safety agency pe20010, was replaced under warranty approximately january 2018. Replacement unit is now showing initial signs of same failure (extremely slow start-up now including blank instrument cluster when entering/starting car; cellular connectivity and navigation failures; unusual sounds or lack of auditory feedback for vehicle controls, blank black screen for backup camera, etc.)
