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.
2015 Tesla Model S driver assistance complaints
Page 3 of 4: complaints 41 to 70 of 71, newest first, as owners wrote them.
While driving in heavy traffic the car's emmc went dead and took over 10 minutes to reboot. All safety driving features were not functioning during this time. This is the forth time this has happened in the past six months. Tesla sent an email that they had a memory module problem with the car's emmc that caused the same problem I was experiencing, so I made a service appointment. When I took it in I was told my car did not have bad memory modules. They said that it was "normal" for the emmc to reboot from time to time, and as a curtsey they would not charge me a diagnostic fee for looking at it. We exchanged several emails about how this could be considered "normal" especially since it was happening more often, but the offered no resolution to the issue. There really appears to be something wrong with these emmc units and tesla doesn't know how or doesn't want to fix it. When the unit stops working I do not feel safe driving the car and I don't know when it is going to happen next.
Vehicle has documented mcu/emmc issues that tesla avoids fixing. Hvac froze/inoperable, charging level froze inoperable to adjust, suspension settings inoperable causing scraping, disabling of autopilot and other navigation and safety features, occured mid-drive originally, now when stationary while vehicle is started it is inoperable/freezes for 7-10 minutes before turning on, often cannot select drive unless it is through the app on phone, backup camera fails/is unavailable or is very slow to appear, often after backup completed. July '20 at 64k miles dealer acknowledged emmc/mcu issues, performed soft reset, claimed worked m, yet aug '20 they had to do again. Vehicle continues to display issues associated with lagging/slow processor, dealer indicates it is not the documented issue abundantly described and consistent with issues on tesla forums across the internet. Further detailed documentation/communication available within tesla app when I submitted to tesla, but here is ancillary supporting documentation attached.
I have the media control unit (mcu 1) and it pretty routinely shuts down while driving which causes a loss of major component functionality. I saw that the federal safety agency is asking tesla for a recall to replace and I think it's really important that tesla do recall these vehicles because the software updates are insufficient to fix the problem. The mcu just needs to be replaced.
The main screen stays blank and the backup camera does not work. All controls that were on the main touch screen do not function include safety features such and adaptive cruise control and emergency breaking.
My infotainment mcu goes blank or is completely unresponsive. This will happen intermittently and without warning. Sometimes I get in my car and the screen remains blank for the entire drive, cutting off access to vital performance features of the vehicle, as well as disabling airbags. I've already taken this to tesla under their 'warranty program', but they refuse to do anything other than reset the computer. They will not repair or replace anything.
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.
2015 model s p85d with failed mcu (media control unit) since beginning of july. Tesla still does not have a part to repair my car. A temporary fix in august only lasted around 4 weeks and completely failed again. When mcu fails, all safety features are not available. No backup camera. No turn signal. No control on headlight so if it rains during the day I can't maually turn headlight on either. Basically just a car that moves and stops without any other function. Tesla is not taking the problem seriously and waiting nearly 1/2 a year and still no parts available is unacceptable. Tesla obviously have parts available to make new cars and are ignoring customer who actually helped a new car company to thrive. Please force tesla to take this matter seriously and
Tesla model s 2015 90d. I have a service appointment come november 30th 2020 for this but I have had multiple occurrences of the main panel and side panel display go completely crash and black screen on me. Disabling both the "autopilot" v1 feature in mid use on a highway going 60+ MPH, GPS and other important assistant information such as vehicle speed etc(because screens are black). Its a very jarring and dangerous experience going fast on the highway and having the car "crash" in such a way that just gas and breaking are all that are suddenly left working in an instance(especially when you have that auto pilot feature engaged on a turn). I strongly recommend the federal safety agency to continue their investigation towards this as there are likely serious flaws with the emmc system and software these early model s cars released with. I am afraid tesla is going to give me the run around and not handle the situation appropriately, which would generally be a consumer recall when events as dangerous as this occur. I would say these full system crashes have occurred at least 5+ times since I have owned the car in 2015 and it seems like a matter of time before a serious crash could be caused by this faulty engineering . Tesla currently is trying to do as much damage control around it offering to look into a replacement part but no guarantees its covered by their warranty. As a software engineer myself it feels very much like when hardware starts to go bad, like a system internals beginning to fail due to corrupt memory and storage. These early tesla model s'es are a ticking time bomb to public roads(I say this as a tesla fan, when working the cars are incredible to drive, when they dysfunction its a very serious problem because of the nature of these software driven vehicles their hardware/software has to be rock solid).
Tl* the contact owns a 2015 tesla model s. The contact stated that while operating the vehicle, the master control unit was inoperable. The contact stated that the back over prevention camera display and turn signals were inoperable. The cause of the failure was not determined. The local dealer tesla atlanta located at 3393 peachtree rd ne, atlanta, ga 30326 was made aware of the failure. The manufacturer was not notified of the failure. The approximate failure mileage was 50,000.
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...
Tl* the contact owns a 2015 tesla model s. The contact stated that the back over prevention camera failed to illuminate properly. An error message was displayed and indicated that the center display was unavailable. The vehicle was taken to tesla (1901 del monte blvd, seaside, ca 93955, (831) 264-6896) where it was diagnosed and determined that the media control unit needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,000.
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.
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.
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.)
Random failure including loss of controls using mcu1. Frequent re-setting / re-booting required to operate the vehicle using mcu 1 controls.
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.
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.
The mcu that operates the car failed.
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.
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.
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 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.
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.
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.
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.
I was parking in my usual parking spot in a parking lot at my office at approximately 8:15 a.m. As I approached my parking spot, I slowed my car by pressing on the brake and made a 90 degree turn into my parking spot. The vehicle was slowing moving forward and was less than 10 feet from where I intended to stop the vehicle when the vehicle suddenly accelerated on its own and crashed into the concrete wall that was at the base of my parking spot, causing the car's airbags to deploy. I did not have my foot on the accelerator pedal at the time the vehicle accelerated into the wall. I informed tesla of the incident and they told me that the vehicle had experienced 100% acceleration immediately prior to the collision with the wall.)
