2015 Tesla Model S electrical system problems

“Many air bubbles are appearing towards the bottom of the instrument panel on our 2015 Tesla Model S. This started a couple of weeks ago and the bubbles are increasing in size and number and they are moving upwards. The bubbles don’t presently obscure important driver information such as the transmission mode (drive, park, reverse, neutral), remaining battery range (e.g. 80%), car speed (mph), parking sensor distance, brake light status, car door open, frunk open, tailgate open, time, outdoor temperature, car lights on/off, warning lights, etc. However, the bubbles likely will do so in the future. Much of this information is vital for safe driving (e.g. transmission mode, speed (mph), remaining battery range, brake light status, and warning lights). As such this display should be replaced by Tesla at nominal or no charge to the owner. According to the internet, the cause of these air bubbles is a failed seal around the instrument cluster that allows a lamination fluid between the LCD display and the cover glass to leak out. It is a very common problem with older Model S’s. It is a critical safety problem.”

“Car isn't cooling while supercharging. Problem originated while at Tesla Collision in Fort Lauderdale. Mike DiPietro, the general mgr stated they don't have a supercharger at Tesla Collision Fort Lauderdale to test it and they're not willing to drive it to the supercharger to test it because it's a service issue. When I dropped the car off it cooled while supercharging and now that it's not cooling while supercharging it presents a fire and safety hazard because it will only cool the moment the car is unplugged from the supercharger and then cools full blast for 45 minutes after the car is unplugged. I am well aware of the proper functioning of the cooling of 2015 Tesla Model S P90DL's because I have two of them and have since 2017. The fact that the cooling system kicks ONLY AFTER I UNPLUG from the supercharger clearly indicates the car sees a need to cool but because of a software issue. MIKE DIPIETRO, THE GENERAL MGR OF TESLA COLLISION FORT LAUDERDALE IS NOW THREATENING TO SUE ME BECAUSE I'M REPORTING A FIRE SAFETY/ACCELERATED BATTERY DEGRADATION ISSUE AND I SIMPLY WANT TO PICK THE CAR UP IN THE CONDITION WHICH i DELIVERED IT WHERE THE SUPERCHARGING WAS…”

“The component that Tesla has stated is the part that is failing is the MCU (Media Control Unit) which was a recalled part at one point but then Tesla decided to replace only a single part of the MCU which was the eMMC (embedded MultiMedia Card). Luckily the vehicle was not driving when it completely shut down and would not start back up but I was stuck in a restaurants drive-thru for roughly 4 hours till I could get a tow truck to come tow it. The tow truck had to put the car on dollies as the vehicle would not enter tow mode nor would it enter its emergency neutral mode so the vehicle could be moved. The windows would not go up or down and luckily the trunk was able to open because if not then I would have been stuck outside my vehicle as the door handles did not come out after I got out of it and closed the door behind me. Please read the messages from the tech as you will see that they tried to act as if they did not know what was going on with my vehicle but then i asked something else and they stated exactly what the issue was but supposedly could not confirm it was that unless they charged me a diagnosis fee and "got hands on" which I'm sure that info of…”

“The window will not go down either due to software, electrical or hardware issues. The window motors have gone out had have had to be replaced. Likely, another motor has failed. In the 2015 Model S in order to open the door the window must lower an inch or more to clear the door frame. When the window will not lower due to software, electrical or hardware issues, the door is difficult to open and may crack/break the window. The is a safety issue getting into and out of the vehicle. The most recent issue is dated below. There have been other issues previously.”

“The MCU that controls the climate and Advanced Driver Assistance Systems stops working while driving. I sent a service request to TESLA and they replied that my older MCU1 is failing because of the new software updates. It isn't the eMMC card hardware failure, but the symptoms and safety concerns are the same. None of the controls work, as the main screen goes blank and resets while driving. TESLA told me the fix for this problem is to upgrade to MCU2, which they fail to provide for free as a safety recall. There was already a recall for the MCU memory chip failing and causing the same safety concern. The car disables the Advanced Driver Assistance Systems when this problem occurs. It happens about once or twice a month for the last year.”

“This is an updated video related to an issue I previously reported. I’m becoming increasingly concerned by the idea that Tesla’s recommended remediation is to replace the car’s MCU. However, the MCU in my car was upgraded to a newer version in July 2021. There are serious safety concerns with the need to perform a “soft reset” while the vehicle is operational (as seen in the video). Please feel free to reach out with any additional questions. [XXX]”
