What the reports in each category say, in the owners' own words
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
Steering got stuck on the road while driving. I couldnt move or change lanes. It was really scary. Then I slowed down and then I had tp pull out of the road to the shoulder. Then I waited for 20-30 mins and restarted the car. Then it worked. I was able to go home. I contacted Tesla and they said they need to look into the issue. At the service center, now they are saying they need to replace entire steering system and the cost is 5000. This is not fair and unprofessional. And it is very scary experience.
Heavy steering warning. Steering gear left hand drive.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
My car has 50,000 miles on it and is just over 4 years old. The steering column has failed causing it to not be able to steer. The service for this is a new steering column at a cost of over $5,000.00. The Y models and 3 models had a recall on this issue. Now it looks like the X models are having the issue as well. The consumer should not be responsible for this. It is dangerous. It is expensive to fix. A steering column should not fail at 50,000 miles. I am not the only person who has been faced with this issue. Tesla service even confirmed that they are seeing this on the X models. I think an investigation should be done. How many $5,000.00 repairs for safety has the consumer been saddled with?
This complain is regarding the recent recall regarding FSD tesla Smart Summon failures. Incident date June 02, 2024 Car was parked in a parking lot outside a movie theater. I was less than 20 feet away from car with clear visibility, and tried smart summon. Car pulled out of the parking making an acute turn damaging driver side door, and front bumper of car parked next to it. Tesla was contacted immediately regarding this malfunction of smart summon and requested them to stop offering this service to owners as it is dangerous. They took 3 months to conduct an internal investigation but refused to share written results. Instead read a generic statement from their website. Still not received a copy of the investigation. Tesla also refused to take take financial responsibility for the damage and their false claim. Smart Summon is dangerous and Tesla should not be allowed to advertise.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
While driving our screen shut down, autopilot and GPS stopped working and the doors would not open. My kids were stuck on multiple occasions and had to climb through the front seats. Tesla has already confirmed that the Driver Assistance System ECU (Turbo A and Turbo B processors) is a known issue. Over 1600 cases reported. This defect disables safety-critical driver-assist functions without warning, which meets the federal definition of a safety defect under 49 U.S.C. § 30102. Provide a free remedy to owners — including replacement at no cost — as required by 49 U.S.C. § 30120. Telsa denied coverage because we are out of warranty. I asked whether the known issue has been reported and why it is not being covered as a known safety defect. Because the problem involves loss of a safety system, it should not be treated as routine maintenance or wear and tear. It is a known safety defect and therefore must be reported and remedied at Tesla’s expense. Tesla refuse to address my concern and would only let me talk to store manager. They told me I had to email business resolutions to get more information. I have not heard back. I was forced to spend $2k to get my car fixed
Compressor fails causing cooling of the battery to fail and AC in the car not to work. System sais AC reduced charging reduced. No Air at all. It seems to be a very common issue. This seems unsafe and is a major expense to fix. $2300+

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
Summary: The front suspension defect on my 2021 Model X, confirmed by St. Petersburg Service Center (Invoice #3000S0013156326), presents a serious safety hazard. Timeline & Concern: Reported Dec 4, 2024, under ESA. Example of Tesla’s delay tactics—service was scheduled only after warranty lapsed. Issue diagnosed in May 2025 as a faulty front upper control arm. Safety risk: Failure could lead to loss of control. I request a safety investigation to prevent similar unsafe compromises.
It is commonly known that the drive shafts on the Model X fail. This is not a wear component and should be a recall. The suspension is also part of this issue and there are after market solutions to fix the suspension that is causing the failure of the half shafts.

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
It is commonly known that the drive shafts on the Model X fail. This is not a wear component and should be a recall. The suspension is also part of this issue and there are after market solutions to fix the suspension that is causing the failure of the half shafts.
The front half shafts have failed 3 times already on this car, creating a safety hazard.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Both Garnish - Fender - Front - LH Right side and Left side come loose when driving in rain. The force of wheels pushing rain water on the fender garnish causes both the left and right fender garnish 4 push clips to come loose. When this fender garnish breaks and flies off it could hit a pedestrian, another car on the road or the car it is installed on causing an accident
My 2021 Tesla Model X has a serious safety issue with the driver’s door. When opened, the door swings freely with no support or soft-close resistance and can slam shut or fling wide open unexpectedly. This poses a danger to passengers and nearby people or property. I believe this issue may relate to a latch or hinge mechanism malfunction, and I am concerned about the lack of a safety interlock. I have reported this to Tesla, and they have not acknowledged it as a warranty or safety concern. I am submitting this complaint in the interest of safety for myself and other drivers of this model. I have videos and more detail but this site only allows static photos.

Unintended, unexpected opening of front frunk hood while driving slowly in a parking lot into a strong wind gust. I did not deploy frunk switch and Secondary latch apparently inoperative

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
Windshield cracked due to defrosting; yes available for inspection upon request. If the windshield shatters due to defrosting this is serious safety risk and what can happen while driving is limited less. Vehicle was inspected by Tesla located in Peabody, Massachusetts and the representative stated they are aware, and this is why they tell customers to warm the vehicle up before turning on defrosting, in all the vehicles I've owned windshield cracking from defroster being on has never happened or been an issue. Also through research I found other Tesla owners have experienced similar. No there were no warnings of this happening outside of reading other Tesla owners experiencing this similar situation.
There is a windshield defect on MY vehicle but check the boards, it is a common problem. The windshield has a mottling defect which is not obvious in normal light BUT - drive into the sun and suddenly you are blinded. It must be a known situation as the boards report this on many different models. We have owned a prior Tesla X so it is not us getting used to the car, it is a defect.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
[XXX] I was driving southbound on [XXX] in Dallas, TX (near [XXX] exit) in Tesla ModelX, with 2 kids in the back seat. It is raining. My speed is around 60-65mph and I am in the rightmost lane. Suddenly the vehicle skids a little, and my steering wheel and brakes are not working anymore. It seemed that the car took complete control and does a full 360 rotation, crossing 4 lanes on the highway. I recall the 10 seconds when I am facing the incoming cars and the only thought I had "this is the end". For whatever reason, the incoming cars slowdown and my tesla makes a full circle, crosses 4 lanes again and gets positioned correctly in the flow of the traffic and in the rightmost lane. my speed now is around 20-30 mph and I suddenly regain control of the brakes and the steering wheel. My kids are crying in the backseat. I still am trying to figure out how and what happened, I cant believe I am alive and I did cry thinking that anything could have happened to my kids. We could have all died on the spot given the rain and how fast the highway traffic goes. I am [XXX] and have been driving for about 30 years. I know how to control minor skidding in rain. I go skiing frequently and can drive on ice (but this was no ice, just water). The only explanation is the malfunction of the Tesla mirrors/cameras (perhaps due to rain water), and taking the wrong decision to swerve the car completely across 4 lanes back and forth. I wish nobody has to go through such life-altering experiences due to a car malfunction, I will never forgive Tesla for the nightmares I still get and the trauma I and my kids had to go through due to the error of a machine. There were no issues before or after with the car, no damage, our tires were relatively new, no police was called. Tesla of course must record incidences like this and they did call me and escalated this to their highest level.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
Since delivery in December 2020 the computer MCU has shut down for two minutes while driving over a dozen times. The computer reboots after a couple of minutes but during this time it disables all instrumentation, turn signals and other driver information. I brought it in to the Tesla Service Center in Highland Park, Illinois with a list of dates and times that it shut down and they told me it was a known firmware issue and that there would be a solution sometime in the future. I don't believe a 2021 Tesla that cost nearly $100 K would force me to stick my arms out the window to make turn signals.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
