Six problems related to electrical system have been reported for the 2020 Tesla Model S. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Tesla Model S based on all problems reported for the 2020 Model S.
The vehicle has been taken to Tesla multiple times due to ongoing controllability and safety concerns. The autopilot system will occasionally brake unexpectedly at green lights or when another vehicle is passing on the right side. The vehicle has also experienced repeated drivetrain issues, including the half shafts failing at least four times within a short period. During acceleration, the vehicle can be difficult to control at times, and the wheels exhibit noticeable vibration. Despite replacing two full sets of tires within two years and completing multiple balancing and service attempts, the issue has not been resolved. These ongoing problems have contributed to premature tire wear and reduced stability, particularly in wet or rainy driving conditions. The vehicle has been serviced by Tesla at least 10 times, and each visit has resulted in replacement of half shafts or other drivetrain components. At one point, Tesla indicated that the drive module was “off center,” though no clear explanation was provided. These issues have been present since the vehicle was purchased in may 2024. In several instances, the vehicle was returned after service without the problem being resolved, requiring additional return visits. More recently, Tesla has suggested the issue may be related to tires and wheels. However, this contradicts earlier assurances that those components were not the root cause. All tires and two wheels have already been replaced, yet the same issues continue to occur. Months go by without any resolution and then when the tires go bad again, they tried to sell me on that when that never resolved the issue. They tried to force me to buy new tires and wheels for $8000 claiming that to be the issue. The main has fell twice in the last year and was replaced with a battery that was not of light kind. When the battery failed at a Tesla supercharger, the door would not open momentarily. I will estimate the date of the last service. Cannot open due to open ticket.
Rear emergency release cable does not open the trunk. The latch mechanism failed with a trunk full of groceries, I pushed down the rear setts to access the trunk compartment and crawled back and popped open the emergency release cable and it did not function. I have a service for the car scheduled for Dec 2nd to repair/replace the latch mechanism.
The contact owned a 2020 Tesla Model S. The contact stated that the vehicle was designed with a safety feature that allowed the front driver's seat to move back when the vehicle was in park (p). The contact stated while at a complete stop and picking up her son, she opened and closed the driver's side door to allow the front passenger's side door to open while the vehicle was in drive (d) and the brake pedal was depressed. However, the front driver's seat moved back, causing her foot to release the brake pedal and the vehicle moved forward. The contact stated that she panicked and extended her foot to reach the brake pedal; however, she depressed the accelerator pedal unintendedly . The vehicle accelerated, crashed into a fence and crashed into an unoccupied vehicle that was parked inside the fence. The air bags deployed. The contact sustained a concussion, pain on the right side of her body, high blood pressure, trauma, loss of memory, dizziness and bruises on her thighs. The contact had been seeking medical assistance. A police report was filed. The vehicle was towed to a tow lot where it was totaled. The contact attempted to notify the manufacturer of the failure but had not been able to reach the manufacturer. The failure mileage was unknown.
I have experienced 5 occasions where the Tesla Model S software and instrument panel has shut down and rebooted while driving. This also happened while waiting at an intersection. The vehicle would not operate properly. Traffic was blocked. All human sense of control is lost. This is a repeating occurrence. Twice I have reported to Tesla and twice they said that they cannot and will not resolve it.
While driving down the freeway at over 65mph, the instrument cluster screen and center display screen turned completely off without warning for approximately 90 seconds. This was very troubling and dangerous. I had no way of knowing how fast I was going, was unsure if my turn signals were working and basically just had zero information on how the car was functioning. During this time, the car did operate as normal though. I did not have the vehicle in autopilot at the time but if I did, I do not believe I would have been able to disengage it. This is extremely dangerous and completely unacceptable. I have not reported it directly to Tesla nor taken it in for service. This is the first time it has happened.
On Sunday oct 11 at 4:15 pm, after a 1 hour ride, I had a 3rd unintended acceleration incident parking my Tesla in my garage. I drove my Tesla 4 times since having our last 2 unintended acceleration incidents on August 18. I had left my seatbelt connected for our last 4 rides and had no problems parking the car in the garage even when hot. This time I disconnected my seatbelt before parking on the two parking mats in the garage. My wife gave me the 'full sign' when both tires were against the 3" mat risers which meant my front bumper was 19" from the workbench. This time I applied the brake before pressing the park button, but again the instant I pressed the park button the car vaulted forward over both 3' mat risers and stopped only 1 inch from the workbench. I could feel the spiked of power to accelerator when I pressed the park. Button. I was truly relieved that I did hit the workbench. I backed up the car and just sat in it for 15 minutes and let the cooling fans run to cool the motors down. My wife took photos of the car in relation to the workbench. The right parking mat had been wedged under the front wheel. The left parking mat mat had been tossed back 4 feet. I know using the second parking mat from my gtr, which I recently sold, helped consume some of the forward energy and prevented the car from hitting the workbench. I feel that disconnecting the seatbelt contributes the trans sensor delay. I parked the car on the mats after it cooled down. There was no driver error involved. I contacted sarasota Tesla service the next day. I sent them a letter and photos which were forwarded to Tesla engineers who again downloaded my edr info. I have not yet heard from Tesla about my first incident. My Tesla has inexpensive defective components in it that make dangerous to drive. I will not let my wife drive the car until this problem is repaired if ever by Tesla.
