On February 11, 2024, as I was entering my house garage at a very low speed, the car suddenly accelerated and hit the wall of my garage, causing damage to the garage and interior of my house. The car was insured by state fram. It was towed to a shop for repair at which time the insurance company notified me that the car could not be repaired. The car had been totaled. Over the following several weeks, I repaired the damage to my house and bought another car.
The rear motor (drive unit) has gone out on this car twice in the last four years. I purchased it after it was last repaired. It most recently went out on 08/04/2023. When it went out two days ago it had less than 30,000 miles on it. This car has a motor on both the front and rear axles, so while the vehichle was still moving forward, if it slowed down at all that would engage the regenerative braking. Once regenerative breaking was engaged, the rear drive unit would normal perform that function, but since it was out, it simply knocked the vehicle out of drive and made the transmission flash red. During this part, steering was affected in that the power steering was out, and the ability to move forward was diminished because the vehicle came out of gear. I was able to put my foot briefly on the brake and then tap the car back into drive, but anytime the car slowed down and engaged regenerative braking, this process would repeat. Looking at the forums, this is a known problem. As already stated, this is the second time in less than four years that this motor has needed replacement. Additionally, Tesla is saying that this motor is did not have a warranty on it, despite the fact that it was replaced only a few years ago. In my opinion, this is a clear safety issue. Reviewing the forums, it seems as though this issue is an endemic problem associated with the Tesla Model S from a range of years between 2012-2015. It is more probable than not that the company is aware of this deficit and has chosen to do nothing about it.
In 2014, I ordered this Model S p85d, received it on 12/20/2014, I also purchased a 4-year extended service plan. Starting from March 2017, it started to encounter random yet serious problems. The car would randomly produce critical errors, displaying several types of error messages, while losing most of its driving power; the driver would have to perform emergency pullovers onto the road shoulder, if available, before the power rapidly reduce to zero. Then the driver need to restart the main computer (sometimes several times), to reset the error messages. Only after that, the car became drive-able again. I wrote an email to servicehelpna@Tesla. Com on 03/23/2017 describing the problem, since then, this became a chronic issue; service centers in virginia, maryland, and san juan pr have performed numerous attempts on this problem, none of them was able to fix it. According to my records, for this issue, the car has been in the shop for more than 10 times, and more than a dozen components have been replaced. The total time it has been out of service is more than 380 days. I now consider it "unfixable" by Tesla. This kind of problem have created many dangerous situations when it occurred on the road, especially when the driver doesn't know how to handle it, doesn't pull over on the shoulder quickly, or there's no safe place to pull over.
Instrument display is frozen at 0mph at 7:57am even while driving. Uploaded photo was taken at 9:19am as indicated on time stamp and on larger display at center of vehicle.
The vehicle went into "reduced power" (turtle mode) error. Which reduced the power and the ability to accelerate out of an intersection and away from incoming traffic. I followed the recommendations of powering the vehicle off. It would correct itself then randomly does the same thing. This is safety issue and needs to be resolved before someone gets into a major accident which will result in great bodily injury or death.
My car has severe phantom breaking due to adaptive cruise control. When I use my Tesla's cruise control on the freeway, on a complete flat straight away that has no vehicle in front of me, no sign/bridge in front of me, and no items/object in front of me, my vehicle while randomly/violently slam on the break violently hurling me and all passengers in my vehicle forward. This is even more dangerous when there are vehicles being me in close proximity who could easily could have rear ended me all those times. I am forced to not use my cruise control due to these dangerous conditions.
We have owned this car for a couple of months. Today, when I pulled into a parking spot at my office, the car accelerated quickly as soon as I made the turn to get into the parking spot. It jumped the curb and I barely missed hitting the office building. My feet were not on the gas pedal, the car did this on its own. None of the sensors went off to warn me of the curb like it normally does too. You can see from the skid marks how hard I had to slam on the brakes. Car damaged on front, assuming the windshield wiper fluid line was also cut with the fluid on the ground. Pictures attached.
The autopilot will apply the brakes in what is basically a panic stop any time you are decending from a hill and there is an overpass crossing the roadway. It happens to me on a particular stretch of the freeway almost every single time, and has happened multiple times. Each and every time it occurs it is as the vehicle is decending from a rise and there is an overpass ahead. For some reason the vehicle detects the overpass as an obstruction and slams the brakes. This has happened at least half a dozen times. Fortunately there was never a car following me very closely. I make it a point when I use the auto pilot to be ready to take over at a moment's notice whenever there is an overpass ahead. The vehicle did this with the old (original mcs) and the new one Tesla just installed.
The accident took place on 7/9/20 around 9:15 am. Police report # 20-1291-ac I drove my car into the parking lot of 4519 post road (facing post road) and turned into the doctor's parking spot. The car had just about stopped and my foot was not yet off the brake when I suddenly felt the car accelerating. It went right through the hedge in front (about 1 foot away) then went smashing through the office marquee, over the stone wall and on to the street. My foot on the brake, I was trying frantically to stop. The car stopped. Relieved, I thought I should quickly get out of the car. To my horror, it started accelerating again. In the next few seconds, it felt as though I was in a james bond movie car chase. The next thing I knew my car was tearing through the white fence of a house and then I remember trying to get out of the car. Which fortunately I was able to by opening the driver-side door. Didn't know hit a tree inside breaking it into two. Found out later the yard was 4-6 feet below the street. Police report is pending at this time.
From a coasting position in an underground garage, I turned right to round a 90 degree corner. After completing the turn my car began to speed up rapidly. When I first noticed the acceleration beginning, I stepped on the brake, which had no effect. The car continued to accelerate over a distance of about 50 feet and collided head-on with a concrete wall. Front airbags on the driver's side deployed and my body struck them: face, chest, and lower legs. I have injuries from the incident.
I have experienced many times that I press the brake pedal and the gas (acceleration pedal on the Tesla) pedal at the same when I try to use the brake. I have own 4 different cars and I never experienced that I am pressing the brake and the gas pedal at the same time. So I pay a bit attention on how the gas pedal and the brake pedal design. I notice the gas pedal is bigger in size and the clearance between the brake and gas pedal is less than all the cars I own (two Lexus and one mercedes bens) or another word, the brake pedal and the acceleration pedal is too close. Also the brake pedal seems a bit higher. Anyway, such design layout seems to cause the driver pressing the brake and the gas pedal at the same time and hinder the action to stop the car. I even experienced that the car accelerate forward when I try to brake the car. I saw the news today that there is a car crash involving a Tesla. I hope the above may be something interesting for you to look into and see if it is related to what I have experienced. Any question, please feel free to contact me.

Car had been rented in November 2016 from a turo member for four days in las vegas. The car had been in stop and go traffic with the autopilot on. The car sensed traffic moving causing the Tesla's autopilot to move at 10mph. Then the car's autopilot malfunctioned and crashed into another car that was attempting to merge lanes. Damages totaled $3100 for the Tesla and unknown for the other vehicle. Car had been advertised as being able to drive itself.
