14 problems related to software have been reported for the 2014 Tesla Model S. The most recently reported issues are listed below.
When starting my vehicle, the vehicle's center console screen did not power on. The instrument cluster (behind steering wheel) did power on, but the vehicle was very slow (about 2 minutes) before it could be put into "drive" (the instrument cluster said that vehicle was powering up). I then attempted to restart the center console screen (mcu) manually (by pressing both buttons on steering wheel for 20 seconds), but nothing happened. I began driving, and noticed several functions were not working: when indicating turn signals, there was no sound, and using a large glass window to verify, the exterior turn signals were not lighting up. The rear view camera and parking sensors would not activate when car was in "reverse" gear. Headlights would turn on automatically when it was dark, but I had no daytime running lights (also verified with glass window). I could also not manually turn headlights / day time running lights on or off. The climate was off, and could not be controlled. Charging was limited, the vehicle would charge but a much slower rate than usual (the instrument cluster said it was charging at only 8 / 40 amps 240v). I continued to drive the vehicle for a week, for short distances, and the vehicle remained in the same state. Several months prior, I brought my vehicle to Tesla for service, because of constant restarts of mcu every time vehicle was started, after a software update. I was told to update to next available version, which did resolve the issue. After further research, I discovered this is the first symptom of mcu failure, and I would experience frequent restarts of mcu while driving afterwards (which I did) until the unit would fail entirely (which it also did). I am surprised Tesla did not warn me of any of these things when I brought the vehicle in for service, instead waiting until vehicle became unsafe to drive.
The main screen on my 2014 Tesla s recently went out and some research online shows that many others experienced the same issues. Tesla sent a technician and said it is the mcu (media control unit) chip that went bad and a replacement will cost $1,500+ the Tesla technician said the car is drivable but the blinkers do not work, along with the back up camera and parking sensors. He stated those things are integrated with the main mcu unit and when the mcu goes out, those things will not function. I am concerned about driving my vehicle without the function of the blinkers as it could present a hazard. There has been reports similar to mine where Tesla added a finite memory chip to the mcu system that deteriorate and will fail after a length of time and because Tesla update the software in the car very frequently, the wear on the memory chip deteriorate at an accelerated rate. The Tesla technician said that the new chip should have 4x the capacity and should last much longer, but will cost $1,500 to replace since my vehicle is out of warranty. With the safety issues mentioned, I am weary about driving my car, especially on the highway - not being able to use the turn signals. If this is a manufacture defect, I do not wish to be responsible for payment to have it fixed. Thank you.
The mcu, which is the large display and control screen started to fail. The heating and ventilation controls didn't work properly, and the bluetooth would not present call history, preventing safe vehicle use. About 6 weeks ago, the mcu failed completely, which prevented turning on the headlights manually. I had previosuly had set them to automatic, so they turned on at night, but I live in off a highway where it is mandatoryfor daytime headlight use, and I was unable to control them the failure in the mcu was determined to be the emmc which is the solid state hard drive in the mcu. It has a limited lifespan and they typically fail when they exceed their expect number of writes to the drive. Tesla informed me that they have changed the software so it doesn't write as much routine data to the ssd. I had the mcu replaced at a Tesla service center on June 12, 2020, at a cost of $2180. 06, since my standard and extended warranty had expired. My Tesla has more than 191,000 miles on it. Most manual controls are inoperative, including the backup camera. Configuring the car is also not possible. .
The contact owns a 2014 Tesla Model S. The contact stated that the vehicle was taken to an unknown dealer to have the passenger frontal air bag replaced under NHTSA campaign number: 18v031000 (air bags) however, the dealer was unable to perform the recall repair. The contact was informed that the cmu software needed to be updated out of pocket prior to the air bag replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 13,900.
My touchscreen went out (all black) a year ago. The replacement was a refurbished one. It took two weeks. When I asked if it was improved, I was told it's the same but has a new two-year warrantee. Now a year later, it is starting to "act up" like the first. Add to that, the last three road trips with it each had something break on it or needed attention. Air conditioning compressor 800 miles from home in August 2019. Driver's door handle extending gear. And 12v battery, only to learn weeks later that it was "fixed" with a software upgrade. What good is an extended warrantee, if you breakdown on a trip? the car is unreliable. I'm going to get rid of it. Just add my complaint to the list of unhappy owners.
After software update supercharging slowed by more than 50% and range on full charge dropped.
Sudden loss of range with 2019. 16. X software update. My vehicle was one of the many vehicles that was effected by software update by Tesla. I have lost about 30 miles in range and the supercharging speed is significantly decreased compare to prior to the software update.
Beginning in June, the subject vehicle suffered from a severe and sudden decrease in the amount of range available as a direct result of software updates issued by Tesla without disclosure to owners. Prior to the updates, the subject vehicle had approximately 255 rated miles available. Following updates 2019. 16. 1 and 2019. 16. 2, the subject vehicle suffered immediately from a range drop to 225 available miles. The subject vehicle has also been unable to charge fully and now suffers from decreased charging speeds. The owner of the subject vehicle went to ncds arbitration, seeking a manufacturer replacement of the battery under warranty, but the arbitrator decided that there was no proof of defect. Tesla claims that this is normal degradation. However, the negative effects were caused solely by Tesla's software updates, for which it has yet to disclose whether there are cars affected and potentially at higher risk of catching on fire. Tesla has failed to communicate anything with regards to the safety of the affected vehicles and has continued to make adjustments to the software without providing owners with any notice or information that their vehicle may be affected. The owner of this vehicle was denied a warranty replacement after having the claims arbitrated with national center for dispute settlement, where the arbitrator found that there was no manufacturing defect. The subject vehicle continues to suffer from a high rate of battery loss when the car is parked and not in operation. The car has not regained any mileage as a result of Tesla's most recent updates that have attempted to remedy the situation. The subject vehicle suffers form reduced charging speeds and is not capable of reaching the same number of miles as it did before.
I have a p85d and since recent software updates my range has dropped significantly. . My supercharger sessions have also become extremely slow resulting in almost an an extra hour to charge the car compared to before updates. These updates seem to be a makeshift cover for defective batteries due to high fire and explosion risk, which have occurred on other Tesla cars. So instead of fixing batteries Tesla reduced their capabilities across the board.
On may 20th, 2019, the subject vehicle was updated with Tesla's software updates and lost over 20 miles overnight. The vehicle has suffered from a throttling of performance, charging speeds, and a lowered maximum battery voltage capacity which has led to a significant decrease in the number of rated miles available. Tesla has denied a battery warranty replacement by claiming that there is no defect. Tesla claims that the updates were issued to improve battery longevity and health. However, they are doing so to avoid replacing these under warranty and/or compensating owners for the loss in range. This appears to be in response to the growing number of battery fires that have occurred with Tesla vehicles that are parked and not in operation. Tesla has failed to communicate anything with regards to the safety of the affected vehicles and has continued to make adjustments to the software without providing owners with any notice or information that their vehicle may be affected. The owner of this vehicle was denied a warranty replacement after having the claims arbitrated with national center for dispute settlement, where the arbitrator found that there was no manufacturing defect. The subject vehicle continues to suffer from a high rate of battery loss when the car is parked and not in operation. The car has not regained any mileage as a result of Tesla's most recent updates that have attempted to remedy the situation. The subject vehicle suffers form reduced charging speeds and is not capable of reaching the same number of miles as it did before.
Software updates by Tesla have limited range usage by lowering the available voltage max capacity for charging. 'parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). '.
Nhtsa action number: dp19005 - investigation subject : battery management software updates - vehicle had sudden loss of battery capacity and charging velocity after software update in may 2019. This has continued with a roughly 15% reduction in the kwh rating of the battery (published rating 85. 0, actual 71. 65). I am disappointed with the reduction in the performance and usability of the car, but more concerned with the potential of an undisclosed defect or risk that I am am not aware of.
Shortly after updating the vehicle with Tesla's software updates 2019. 16. 1 and 2019. 16. 2, it was discovered for the first time that the vehicle had suffered from a sudden and immediate loss of approximately 26 miles of range as a result of the pair of software updates. The updates in question also severely decreased the supercharging speeds for the vehicle. In addition, the software updates issued by Tesla did not disclose anything with regards to the range loss or decreased charging speeds. Tesla has released updates since initial range-reducing and charge-speed limiting updates which were supposed to and purportedly were issued to correct the problems, however, there is no significant change or increase in range or charging for the vehicle to date. Note - this complaint has been submitted by legal counsel who currently represents the affected owner for this specific vehicle. Legal counsel here also serves as counsel to the putative class members and named class plaintiff in the litigation currently pending in the u. S. District court, northern district of CA, case no. 5:19-cv-01422-vkd.
My li-ion battery has been degraded recently by an over-the-air software update. I believe that this update is related to the recent battery fires (4 in ladt 4 months, including one in san francisco). Only a few (100 to a few thousand I believe) of the Teslas have been affected as mine has been. I am now concerned about the safety of my vehicle. Will my battery catch on fire in my garage? I would like NHTSA to review the changes made by Tesla and approve that these changes will be effective for the safety of my battery. Or, does this point to a defective battery and should be recalled for safety reasons?.
