2018 Tesla Model X problems

FORWARD COLLISION AVOIDANCE: WARNINGS

My vehicle intermittently and without warning disables Autopilot/cruise control while driving, most consistently during hard acceleration from a stop or low speed. The touchscreen displays "Take Over Immediately" and Autopilot becomes completely unavailable for the remainder of the drive. The system only resets after the vehicle is parked and allowed to sit. This has occurred repeatedly over multiple weeks, documented via the vehicle's own Service Mode diagnostic logs, showing the following recurring fault codes occurring together, dozens of times between approximatelyXXX and XXX: PM_w041_dasMIA – "Pedal Monitor Warning: DAS CAN node is missing" DI_w124_cruiseFault – "Drive Inverter Fault: Cruise faulted," user-facing message "Cruise control disabled" I brought the vehicle to a Tesla Service Center. Technicians stated they could not identify a specific cause, but acknowledged they were aware of similar cases from other owners of this vehicle model reported on Tesla's internal systems. No repair or resolution was offered. This vehicle is equipped with an HW3 (FSD Computer 3) Autopilot computer and Full Self-Driving Capability (purchased package). Tesla CEO [XXX] publicly confirmed on the company's Q1 2026 earnings call (XXX) that HW3 computers do not have sufficient capability for current and future Full Self-Driving software, and announced a remediation plan for affected owners. I have not been offered any remedy. I am concerned this represents a safety-relevant defect: the sudden, unpredictable loss of Autopilot/cruise control during active acceleration, particularly on-ramps or intersections, could create a hazardous situation for the driver and surrounding traffic.

The falcon doors on the model X, when it is a hot day, and the sun is hitting the door, these doors will not open under any circumstance, resulting in a major safety issue. should there be an accident, a fire or other issue where someone needs to exit the vehicle, they are simply not able to do so under any circumstance! This is a known problem with these vehicles, if the sun hits these doors or it’s a hot day. There are hundreds, if not thousands of posts about these doors, not opening when the sun is hitting the door for a prolonged period of time or the door gets hot. There needs to be a recall for this issue. From my research, seems that there’s some sort of sensor adhesive that comes loose or something similar to that. And either case this is a major safety issue, as it does not allow the passenger to exit the vehicle under any circumstance. Even holding the override button on the screen does not open the door. My kids have been stuck in this car on a repeated basis due to this issue of the door, not opening due to this failed sensor. Tesla is aware of this issue, and has never issued a recall, even though they know it affects all of the model X models

STRUCTURE:BODY

The falcon doors will not open under any circumstance if the car is sitting in the sun. This is a known issue by Tesla with thousands of online complaints by owners. It seems the glue that holds the sensor comes loose in the heat. This is a major safety issue by NHTSA’s own standards. Not being able to exit the vehicle is directly listed as a reason for a recall by NHTSA. You need to force Tesla to issue a recall for this known issue by Tesla

ELECTRICAL SYSTEM

For the past year, the battery will not hold it charge. I am getting about 30% of predicted mile range in colder weather and about 50% of predicted range in warmer weather. This makes the car unusable except for short trips and even then requires frequent charging. In addition, intermittantly, it will not charge quickly at a Supercharger. When others cars present are charging 180 range mph, I am charging at 20-50 range mph. I have had Tesla evaluate the issue and they claim there is nothing wrong but refused to share their evaluation with me. The rep would not give me any specific reason for my problem other than they found nothing wrong. I started the process before the end of the battery warranty (8 years) which has now expired. I feel Tesla service is committing systemic fraud in their approach to warrantied battery failure.

I own a 2018 Tesla Model X that has multiple breakdowns ( 3 times to date: Feb.28, 2026, Mar.7, 2026, Mar.14, 2026) resulting in the vehicle becoming undriveable and could not be shifted out of Neutral. During driving on separate occasions, the vehicle displayed multiple safety warnings and critical systems became disabled. Alerts shown on vehicle included: 1. Automatic Emergency Braking unavailable 2. Power braking Assist reduced 3. Parking brake not applied 4. Safety restraint system issue 5. ABS disabled 6. Park Assist unavailable 7. Service required Following these alerts, the vehicle became undriveable and could not be shifted properly, remaining stuck in Neutral. The vehicle therefore could not be driven safely. The vehicle was previously taken to a Tesla service center after an earlier breakdown. Tesla reported cleaning corrosion during service, but shortly after the vehicle was returned, the problem occurred again with the same or similar safety warnings. This issue is concerning because multiple braking and safety appear to fail simultaneously, including ABS, braking assist, and restraint system alerts. The vehicle becomes undriveable and may create a dangerous situation. Given the repeated breakdowns and the disabling of critical safety systems, I am reporting this issue for investigation.

POWER TRAIN

The 2018 Model X experienced a sudden and complete loss of power and became totally inaccessible. All doors and access points were inoperable and the vehicle could not be unlocked, disconnected, powered on, or placed into any service or tow mode. Emergency front-trunk release cables had to be used and external 12-volt power applied at the jump terminals to wake the vehicle. The inability to access the vehicle was unexpected and alarming. Children, pets, elderly, and others could have been inside of the vehicle. Thankfully, they were not. Tesla inspected the vehicle and stated the failure was related to the battery coolant heater. The failure resulted in a complete vehicle immobilization and access failure. I had previously experienced restart warnings on the dashboard, but I did not expect a total lockout and loss of access. The inability to access the vehicle was unexpected and alarming. It may be a known safety issue. It should be recalled. This condition presents a serious safety risk because occupants could be trapped inside the vehicle and the vehicle cannot be accessed or moved without external power. In extreme heat or cold, or in a medical or emergency situation involving a child or pet, this failure mode could create a life-threatening situation. Importantly, even after multiple requests, I have not received a copy of the diagnostic report, or anything other than informal emails or calls. Tesla has not provided information regarding this failure other than broad statements, and visuals of the location of the battery pack, in an attempt to deny warranty coverage. The Tesla reports a High Voltage System alert currently. The vehicle is subject to Tesla’s Battery and Drive Unit Limited Warranty. Tesla has stated that the failed component was the battery coolant heater, but has refused to cover the repair under warranty. Tesla confirmed the failure but has not provided the diagnostic report, fault codes, or vehicle logs supporting its determination.

During a recent incident where a tire issue caused damage to the wiring harness for the parking brake, resulting in a Parking Brake Failure notification on the screen, the vehicle would not stop or turn off. The vehicle displayed N for neutral on the dash, but the vehicle would drive forward unless the brake was depressed. In addition, we were unable to place the vehicle in Park, which meant that we were unable to shut it off. The only way to stop the vehicle from driving on its own and crashing into something was to place concrete blocks under the tires! Unplugging the 12v battery also had no effect! The vehicle kept driving as if it was in drive, and there as no way to stop it without placing the foot on the brake pedal the entire time or placing the blocks I referenced. The only way I was able to shut it off, was to pull what's known as the Fireman's Loop, which I'm guessing firemen pull in the case of an accident. I wasn't aware of this mechanism, and only learned of it after posting on numerous social media apps regarding this issue. This is a Major issue, as we are talking about a moving and unstoppable car! Tesla needs to build some mechanism that allows the car to be shut off by the driver or to override the screen and place the car in park. Pulling this firemans loop and unplugging the 12v battery, required me being in front of the vehicle, risking my life, as the vehicle could've easily moved if the concrete barriers didn't stop it, and also required me taking 30+ minutes to remove components from the Frunk, just to access these components!!

TIRES

265 45R 20 As I was driving down the road, I heard a flapping sound. I couldn't pull over right away, as I was in the left lane, and there was a lot of traffic. I pulled over, but I couldn't put the vehicle into park or turn it off! After a family member showed up. i had them put their foot on the brake, while I investigated the issue. I noticed a long piece of tread that was handing from the inner tread. Then I noticed that an entire line of tread was missing as well. The hanging tread cut through the protective lining for the wiring of the vehicle. Then it tore up some wires, which I later came to realize were the brake wires. This is a Tesla, and I was not able to put it into park. The car is is still in drive, with no way of putting it into park or turning it off! This tire has caused significant damage to my rims and vehicle!

Water entered the passenger cabin of my vehicle during normal rain exposure while the vehicle was parked overnight. The failure occurred at the roof glass/seal system, allowing rainwater to intrude into the interior behind the second-row seating area and soak the carpet and underlying padding. This resulted in persistent moisture and a strong musty odor inside the cabin, consistent with microbial growth and mold risk. The condition affects interior air quality and poses a potential health risk to vehicle occupants, particularly children or passengers seated in the rear. Prolonged moisture inside the cabin also raises safety concerns related to corrosion and possible impact to electrical components, sensors, and restraint systems routed through the interior floor area. The condition substantially impairs safe and normal vehicle use. The presence of moisture and microbial odor makes the vehicle unsuitable for passenger transport and creates uncertainty regarding the integrity of interior and electrical systems. The issue was inspected and confirmed by the manufacturer’s authorized service center. The service center documented that water intrusion occurred through failed or missing sealant around the roof/door glass assembly and confirmed saturation of interior carpet and padding. The manufacturer recommended replacement of interior padding for safety reasons but declined responsibility due to the vehicle being outside the basic warranty period. There were no warning lamps or messages prior to discovery. The issue was identified after rain exposure when wet carpet and odor were observed. The problem is reproducible under rain conditions. The vehicle is available for inspection upon request.
