With 44k on odometer the mcu went out. I had to drive around with no way to adjust charging level, no turn signals, no back up camera, no climate control. Without the mcu the center monitor went out. Tesla wanted about $2000 to fix it by replacing it with the same problem board. My car was beyond warranty by just a couple of months. They knew in advance this mcu was going out based on how many times I had to restart the system when it crashed.
2015 Tesla Model S electrical complaints
Page 9 of 10: complaints 221 to 250 of 269, newest first, as owners wrote them.
The screen on the car went blank as the mcu failed. While the car worked the audio, autopilot, radio, GPS, navigation, turn signals stopped working. The car only had ~46,700 miles on it when the screen failed. Clearly a defect which should be covered by tesla 2 months after the warranty expired in dec 2019. This happened while the car was parked.
Mcu failed - black screen that made many vehicle controls (back up camera, odometer) non-functional.
Approximately 5 years after purchasing my tesla model s, the media control unit failed while I was driving on a city street (doing a reboot due to some system failures). Much of the functionality of the car became inoperable because of the failure, including climate control, navigation, music and more. A week later tesla's mobile technician did a hard reboot, which then eliminated the ability of the car to charge (making it effectively inoperable). When I finally got an in-shop appointment, a week later, I had to pay to replace the mcu, as my warranty period was over. Even now, there are continuing issues with the voice recognition system.
My mcu failed in january 2020 and I was charged $1,429.73 for replacement. I found a news article today that the federal safety agency is investigating this issue, I wanted to add my complaint as well. There was no incident preceding the failure, it just went dark one day. As a result heating/cooling, navigation, audio, etc. Were unavailable while I waited a month for the service appointment.
Mcu failure with less than 3,400 miles on car. Tesla claimed it was out of warranty. The car can not charge or do anything without mcu. No windows, no climate, no charging, etc. A solid state device like the memory should not fail. It is being overwritten two often and tesla should have spec out better memory. Further the unit failed with very low miles and usage. I tried to find the invoice but it seems tesla keeps the invoice on their server. A failure of mcu because of under spec memory should not be the consumer issue. Tesla should replace the mcu or memory for free. I am very upset the way this was handled. Furthermore I was told I would be getting a new mcu with upgraded memory but now I have doubts after reading teslamotorforum.com that I will have another failure in the same time period. This is a safety issue as the mcu controls more than entertainment but many car functions necessary to drive.
Mcu failure (march 2020) from emmc memory wear-out resulted in non-functioning car. Car would not "turn off," thereby entirely draining batteries. Since the air conditioner was on during mcu failure, it would remain on, no matter what I did, thereby (a) running down the battery, and (b) potentially creating a maintenance or fire hazard (AC running for 12 hours). Also non-functional was cruise control, radio, rear camera, audible warnings (like turn-signal clicks), inability to control battery charging, loss of navigation, parking warning chimes, energy usage graph, cell features, etc. Significantly, the "creep" feature, which moves the car forward when pedal is lifted, also did not work -- causing me to have to relearn certain drive features, and at one point allowing the car to roll backward when it usually would have creeped forward. It's unknown if certain emergency braking features would have worked. Main vehicle control systems functioned (steering & brakes), but nothing else did, and driving was very concerning. Cost to repair was $1575. However, the same type of computer was installed, which leads to concerns that the same problem may occur in the future. See also the federal safety agency action number: pe20010.
The mcu/screen stopped working and I was able tondrive, but not use any safety features, including blinkers, back-up camera, or navigation. It took over a week to get a service appointment and the item was not covered under warranty, so I had to pay over $1600 out of pocket. The car was not in motion when the failure occurred, and I was able tondrive, though not as safely as expected.
Failure of mcu console leading to loss of back up camera, climate, radio and all controls related to car settings including safety settings. Tesla unable to repair for weeks with no loaner leading me to drive in this questionably safe situation. Mcu replaced with mcu that has the same memory chip issues and will likely fail sometime in the future. In addition since replacement car has had issues with instrument cluster resetting. This has thankfully not happened while driving.
Tl* the contact owns a 2015 tesla model s. The contact stated that while driving the vehicle, the master control unit (mcu) failed to illuminate or operate as designed. Due to the failure, the back-up camera, the turn signals, and hazard lights were inoperable. The vehicle was taken to tesla of van nuys located at 6919 hayvenhurst ave, van nuys, ca 91406, and the contact was informed that the mcu needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 40,000.
Tl* the contact owns a 2015 tesla model s. The contact stated that while driving, the navigation system displayed a message indicating that service was required. The vehicle was taken to tesla (840 providence highway, dedham, ma 02026; (781) 471-3001) and the contact was informed that the media control unit needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 41,339.
My mcu or main touch screen has failed. I no longer have control of navigation, music, HVAC controls, back up camera, turn signals, autopilot, adaptive cruise control, headlight controls, sunroof controls, or any function besides driving, steering, and braking, the car was at my home when it was receiving an over the air update. The car then notified me that the download had failed. I went out to the car to find the screen completely black. Trying to reset the screen did not work and tesla diagnosis LED me to believe that the mcu no longer works. Doing my own research I had my emmc chip looked at and found the files were corrupt and the chip was 90% full. Tesla will not replace just this chip and only the mcu in full. I have not driven my car since this issue. *ln*jb
Primary touchscreen failure (mcu). The car was stationary parked in garage. The primary touchscreen failed and would not start. Air conditioning, turn signals, and backup camera stopped working, along with all other settings because non-functional. Car is 5 years old and 45,000 miles. The mcu touchscreen had to be replaced.
Media control unit went completely out after a few months of trouble. Car took longer to start up and controls of safety features were not working. This happened while starting car and also was not available while vehicle was in motion which caused a dangerous condition.
2015 tesla model s with 39,000 miles had centre screen fail. Car is unable to be driven. No controls are active. Known issue with emmc chip. Car was stationary at the time, will not reset.
Touchscreen failure.
On june 9 at approximately 10:30pm, the car accelerated on its own at a high rate of speed. The cruise control was off, as such, so was the driver assist mode. In addition, without prompting, the sunroof opened and the windshield wipers turned on. The only way to stop it was to reboot the computer. The fact that tesla denies this is a problem is ridiculous. There is clearly a software issue that has been recently introduced. I have had the car for more than 5 years and have never had this type of problem until now.
Own a 2015 tesla model s 70d. Last summer, july or august, I noticed a significant change in the rate of charging at superchargers. Previously, I received 100kw or more and now at the same battery percentage, it is charging much slower. I checked the tesla forum and others noticed the same issue. It appears this is linked to a software update. It seems to only affect batteries of the same era as mine. We own other teslas, and this is not a problem. I believe there is an issue with this battery and that tesla modified the rate of charge to mask the problem. I am enclosing pictures showing the same percentage of battery at 4 different locations. Two are before the software change and two are after.
Sudden unintended acceleration. I had almost completed a u turn (but not completely) to slowly pull into a parking spot parallel to the sidewalk when the car all of a sudden lounged forward (see skid marks). It only slowed after hitting and damaging the brick wall.I pressed on the brakes, the screen flashed something like: your auto park is now disabled. I was able to slowly ease into my intended parking spot and come out and assess the damages. It all happened over a split second. The collision definitely felt like there's a major fault with the car's computer system - instructing it to lurch forward at rapid speed and not able to autostop with an object (brick wall) in front of it. I was at a residential area within a gated community. When california highway patrol came, they said they couldn't file a report within private property.
The main computer display and memory card fails - freezing all safety monitoring of the car, lose control of charging (I.e. Refueling) . Suspension control lost, basically everything frozen without this - it is known common failure emmc chip
Mcu failure due to mmc drive failing. Known issue for months. No parts. Cannot charge and therefore cannot drive. Been a week with no communication. No plan.
No warning whatsoever, the 17' touchscreen goes black on our model s. I try the reboot, but nothing happens. It's early february, so here in alabama, it's cold. We keep the car in the garage. No climate control is working. We pull out, head to my wife's families house 7-8 miles away, and the windshield has a couple of inch strip at the bottom that visible. So driving between 10-15 MPH, we make it to their house. I finally get ahold of tesla a little while later. After about 30 minutes or less on the phone with them, they said they see what the problem is. The lady stated that the tesla engineers know about this problem and have been working to get it fixed. I was originally scheduled for repair on february, 17th. They contacted me two or three days before then and said they were anticipating the part to arrive on february 27th, so they proactively rescheduled my appointment for february 28th. After calling, emailing and then finally chatting tesla on february 27th, they said the part still hadn't arrived. They told me they were going to escalate my case and they also rescheduled my appointment for march 13th with no guarantee that the part would be in by then. A loaner vehicle wasn't offered after asking multiple times. The reason was because my vehicle was out of warranty. We purchased this vehicle used from a third party, not tesla. We had the vehicle almost a year and a half before this happened. The vehicle was stationary. We are on rural to country (not dirt) roads. The HVAC doesn't work at all, nor does the parking sensors. Navigation is out, pretty much all the extra features (mostly) you can forget about using.
Loss of battery range of 40 miles after software update.
The main instrument panel (call the media control unit or "mcu") eventually fails in all older teslas (pre 2018) due to a defect in the design of mcu and overuse by excessive writing of data to the memory with firmware updates as well as logging for tesla's own purposes. The consumer has no ability to turn off updates or logging which means that tesla is causing the failures with its own actions. The mcu has been shown to fail within approximately 4-5 years (or right after the warranty expires). This is a significant safety issue as once the mcu fails, many functions of the car fail. This includes the backup camera, the audio indicators for turn signals and other alerts, climate control, as well as the safety monitors associated with "auto-pilot" (e.g. All restrictions are removed). Tesla's position is that the consumer must pay to replace the mcu once it fails if the car is out of warranty. They have upgraded the mcu design and logging process for newer teslas (post 2018) but all cars from 2012 to 2018 are affected by the original defective design and process. Hence, this petition is to require tesla to acknowledge the defect in the original mcu and replace via recall, and/or compensate customers who were forced to pay for replacement.
12v battery has started failing, been over 2 months, tesla keeps cancelling appointments to fix. Car is going to die on the road on me.
April, 2019- my model s was stationary at a supercharging station, battery not charging normally, interrupting with error message: battery "recalculating". A 90% charge normally resulted in 242 miles of rated range. Suddenly, a 90% charge now results in only 210 miles rated range. Since new, the battery gradually lost a total of 3% of range, or 8 miles, over 3.5 years. Suddenly, the loss of range is an added 15% or another 32 miles. The car now charges at a much slower rate. Normal supercharger rate of charge starts at 116 kw. Now, starts at only 60-80 kw. Charging now taking much longer. I contacted tesla multiple times, with the above information. I have received no repair of issue after numerous attempts at receiving service. I've received many nebulous, conflicting, and untrue statements from tesla, refusing to confirm clearly what has caused this battery performance and charging problem. At one point, they indicated "the charging rate and your battery's capacity was limited to prevent over degradation of cells and damage caused by overuse of supercharging." another tesla rep stated it was caused by a firmware update, but no one has put that statement in writing. But, they still insist the battery has no problem, and needs no repair. If there is no problem with my battery then why did tesla cap it's voltage and charging rate with a firmware update? Why will tesla not restore my car's performance? Indications are such that either the battery should be repaired or replaced. Considering that this firmware update coincided with some tesla battery fires, I am concerned that a faulty battery could present a dangerous condition. Tesla has not been forthcoming with information, only refusing to repair the issue.
The cinch motor that hold the rear trunk closed had malfunctioned. The trunk will no longer close fully. It rattles constantly and warning sounds go off for the first minute of driving. The trunk could fly open when I go over bumps. It is going to take tesla over two weeks to repair. And they are going to charge several hundred dollars for the repair. I believe a recall is in order, given that this is a common problem and a safety issue.
Re: the federal safety agency action number: dp19005 - investigation subject : battery management software updates our tesla model s software "update" greatly reduced the amount of total charge, and speed that we can charge our battery. We called tesla, and initially they said that our battery had "degraded" and that was causing the problem. We responded that our battery is not even 4 years old (the car was purchased december 22, 2015), and batteries don't suddenly "degrade" 15 - 20% in one week. Tesla maintenance then admitted that the problem is due to a software update that reduced the speed and total charging of the battery "out of an abundance of caution". The service rep assured us that he was looking at our battery stats on line and there is nothing wrong with our battery. Fine, we said, if there is nothing wrong, take the crippling software update off. Sorry, can't do that, was the response. Your car is one of a number of cars that have had battery fires. It has a gen 1 battery (built before april 2016). We are researching the problem, and do not understand why this is happening. Ok, if you are aware of defective batteries, just replace our battery. The response was "sorry, we cannot due replacements at this time." my wife needed to drive 500 miles up to oregon to be present for her mom's cancer surgery last week. She could not take her tesla, as it now takes an hour and a half to "supercharge" the amount it used to receive in 35 to 40 minutes. She is afraid to drive the car. We read that in at least one of the tesla battery fires, the electric door handles would not operate and the passengers could not get out of the car. The tesla carries our family and loved ones. Tesla appears to be putting economics above safely in this matter. We need the federal safety agency to investigate to determine if it is safe to continue driving this car. Thank you.

My car's charging speed was significantly reduced following a software update. I used to charge at 116kw until about 25% state of charge but now I barely get 90kw at that state of charge.
