12 problems related to air conditioner have been reported for the 2015 Tesla Model S. The most recently reported issues are listed below.
My center screen that controls the vehicle functions such as air conditioning, all vehicle settings, map, cruise control, vehicle collision sensors, lder, etc are not functioning because the mcu unit failed. The emmc chip inside mcu failed when the vehicle was downloading a update sent from Tesla over the air. The car doesnt want to turn on half the time and vehicle driveability and functions are very limited. Tesla hasnt responded to my complaints and my issue. The car was in my driveway and downloading when the screen qent black and nevwr turned back on. I took it to a Tesla 3rd party shop and they advised me to keep calling Tesla to notify them of faulty mcu and emmc unit. The danger is that the vehicle collision and safety features are disabled and its dngerous driving on roads.
Mcu goes blank; this effects exterior lights; acceleration settings; steering modes; regenerative braking; stopping mode; the entire sound system, including the turn-signal tones; displaying warning notifications; critical gauges; gps navigation; self-driving mode; rear view camera; ability to charge; suspension; heating and air conditioning; and the sunroof.
On July 23, 2020, at around 1:00 pm, I was highway driving at 65 mph on east bound I-70 near blue springs, mo. When my touchscreen failed and went blank. I lost access to all my touch screen features and it rendered my Tesla app on my mobile phone in operable. I was able to drive it to the Tesla service center in kansas city, mo. On same day. On July 23, 2020, around 2;05 pm, I was advised by Tesla that my touchscreen failed and will have to be replaced. My Tesla was not drivable as it could not be charged and the air conditioner could not be turned off. I left my car with the Tesla service center mentioned above and I authorized replacement of the Tesla touch screen. I was informed by Tesla that my car was out of warranty and the cost of the touch screen replacement would be at my expense. I authorized the repair. The mileage on my car is about 25,000 miles. Tesla presently has my car in their service shop as it is not safely drivable. The replacement screen has been ordered and should be installed and my Tesla ready for pick-up on or about August 4, 2020.
Touchscreen completely inoperative which impact ability to control turn signals and air conditioning.
Media control unit screen went blank while vehicle was in motion. Vehicle still drives, but driver is unable to use navigation or media functions. No turn signal feedback. No backup camera. Worse, unable to control ac that was running at the time of incident. Air conditioning still runs after vehicle supposed to be stopped, draining battery. Vehicle had to be parked for 48hrs + with ac running constantly until brought to dealership. Service wants $1700 for a replacement, or $2250 for an "upgrade".
The Tesla media control unit completely failed on 7/5/20 after being unable to turn back on. The vehicle was stationary and was parked on the street. Due to the failure of the media control unit, the systems such as the air conditioning, backup camera, controls, etc were unable to be controlled which posed a significant safety hazard.
The center screen (mcu) has glue running inside the screen of the entire unit and then leaking out the bottom. The screen now also turn off (reboots) at different time while driving thus incapacitating the review camera, air conditioning and other functions for up to 5-8 minutes while system reboots. This happens while stationary and in motion. .
Mcu1 touchscreen has an expected short life span due to Tesla's logging practices. This practice shortens the lifespan of mcu1 (main control unit) devices significantly and hinders touchscreen capacity, removes auto pilot capabilities, and prevents air conditioning control or media control.
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.
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 NHTSA action number: pe20010.
I understand you are investigating Tesla Model S computer failure. I would like to list the issues I have had since I brought my Model S in March 2015: -April 2015 ? front trunk would not open. Latch was replaced under warranty. -June 2016 ? driver door handle stopped working. Replaced under warranty -August 2019 ? media control unit failure (touchscreen). Happened on a Friday and I could not see in reverse, could not use handsfree phone ? important for me as a critical care physician answering calls from the icus. Could not closer sunroof. Car could not be shut down. The air conditioner stayed on for 3 days until I can get the car to service center. Car had to remain plugged into charger to support the air conditioner etc so I had enough battery reserve to get to the service center. My cost $2134 -August 2019 ? a/c failed after having run nonstop for 3 days b/c of mcu failure. My cost $869. -August 2019 ? in effort to shut down the car, per Tesla phone instructions, I disconnected the battery and charged it. As a result the battery shaped ballooned out and I had it replaced since everything was open. My cost $216.
Monitor failure. With lost of navigation, air conditioning etc. While stationary. Happened 2018. Replaced monitor and I was charged 2000 dollars.
