2019 TESLA MODEL X Complaints

The contact owns a 2019 Tesla Model X. The contact stated that the Full Self-Driving system was updated in June 2025. Since the update, while idling at red traffic lights, the vehicle was surging forward as if it were trying to run the red light. The contact had to immediately depress the brake pedal to prevent the vehicle from accelerating unintendedly. While attempting to make a right lane change, the vehicle suddenly seize mid-lane-change and returned the vehicle to the original lane. The contact made 2 to 3 attempts before being able to make the lane change successfully. The vehicle also independently attempted to make the lane change as if self-correcting the vehicle. The failure was intermittent. The vehicle was taken to the dealer, and the vehicle suddenly ran a red-light while being test driven. The contact stated that the dealer expressed that it was a known issue after the software update was completed. The vehicle was not diagnosed or repaired. The vehicle was taken to another dealer, Tesla (1731 Fourth St, Berkeley, CA 94710); who was unable to diagnose or repair the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 5,000.

Advanced Driver Assistance Systems (ADAS) – Safety Incident Report: While using the vehicle’s ‘Summon’ feature, the car failed to stop when I released the control button. It continued forward, drove up and over a large curb, struck a signpost, and came to rest with one tire elevated on the curb/grass and the other three tires on the pavement. This “jumping curbs” behavior and collision with fixed objects represents a serious safety hazard. I am extremely grateful that no person was nearby or inside the vehicle at the time, as this failure could have resulted in injury or death. The incident is documented on video. The vehicle is currently pending inspection. Despite my request, Tesla has not responded or addressed the issue, leaving the defect unmitigated. At no point did the vehicle display any warning lights or messages indicating a malfunction before or after the incident. Given the nature of this failure, its potential to cause harm, and the lack of response from the manufacturer, I am submitting this report to alert federal safety authorities and initiate appropriate investigation into the safety of the ‘Summon’ feature and the vehicle’s ADAS systems.

I own a 2019 Tesla Model X. After Tesla upgraded my vehicle from AP2.5 to the FSD hardware module, the front camera view became blurry. I disassembled the camera housing and found that a heated line in the windshield, intended to prevent fog or ice buildup in front of the camera, runs directly through the camera’s field of view. This line now causes noticeable image distortion, which interferes with safety-critical features such as FSD, forward collision warning, and lane keeping assistance. The Tesla service supervisor confirmed this is not my fault. He explained the issue may have been caused by heat from the line gradually affecting the glass, or that the upgraded FSD hardware, which captures clearer images, is now revealing a flaw that was previously less visible. He also mentioned that Tesla redesigned this component in newer Model X vehicles to prevent this issue. However, because my car is out of warranty, they are refusing to replace the windshield. Since the FSD upgrade, I have experienced multiple warning messages while using FSD. On one occasion, while driving on the freeway, the system suddenly disengaged and displayed a message saying the camera had weak visualization and the driver must take over. I believe this is a serious safety issue related to the blurry front camera caused by the heated line in the windshield. Although Tesla acknowledges the problem and that it is not due to misuse, they have declined to offer any resolution. I am now unable to safely use the FSD system I paid over one thousand dollars to install, and Tesla has taken no responsibility. I believe this issue poses a risk to driver and public safety and should be investigated regardless of warranty status.

While driving normally at around 30mph and without warning, the vehicle displayed multiple warning messages related to the HV Battery and lost all motive power in the middle of the road with insufficient time to pull over, creating a safety hazard. Upon inspection by a mechanic independent of Tesla, the HV Battery was found to have multiple voltage sense leads disconnected from the flexible PCB pads that lead to the BMB for each module. One of the 96 bricks had all four sense leads disconnected, resulting in the loss of motive power due to the inability for the BMS to accurately measure the voltage of that brick. In fact, the vehicle displayed module over voltage and under voltage alerts due to this open/high resistance sense harness connection. Out of all 96 bricks, 13 bricks had at least one loose sense lead, and one brick (besides the affected brick) had 3 out of 4 sense leads loose/disconnected from the PCB pad. Any loose leads were only at the PCB pad end, not at the current collector end. These sense leads are ultrasonically welded through the same attachment process as the cells, but the connections to the flex PCB pad are clearly not as robust as the other connections or are exposed to higher vibration over time due to relative motion of the flex. The flex PCB design was introduced in 2015, just before the Gen 2 HV Battery, and in production until the 2021 refresh. The HV Battery did not ever have any visible liquid ingress or physical damage. It is my understanding through various forums such as Tesla Motors Club that this is an increasingly common issue, and that Tesla is experiencing a high rate of this open voltage sense harness issue at their service centers for vehicles that have not been in any prior accidents or incidents (forums generally only have salvage vehicles that are out of warranty). Errors typically are: BMS_f107_SW_Cell_Voltage_Sensor BMS_f177_OpenVshDetected BMS_w129_SW_BMB_VSH_Connector Or their variants (a129, w177, etc.)

I got my suspension replaced on my 2019 Model X (that I bought used from Tesla directly) in June 2023. Tesla was suppose to do a through 140 point inspection before putting the car for sale on their website but after less than 2 years and 15000 miles (after the suspension was replaced). The same suspension same issue came up. Tesla told me that they need to replace the suspension again and will bill me $2100. I have owned multiple cars but I have not have to replace suspension on any of my cars ever. How can a suspension fail first at 35000 miles and then again 15000 miles. This seems like Tesla is knowingly putting faulty parts in the car to keep making money on parts and labor. This should be looked into and investigated by National Highway Safety. And Tesla should issue a recall for these and replace them with good quality parts.

I plugged in a tester into the 7 pin trailer harness that is factory installed and the harness does not work. Specifically, there is no 12V power coming from the harness. I googled the issue and it is very common on 2018 and 2019 Tesla Model X’s, and people say when they went to the dealer they said that the factory wired it incorrectly but that it was a simple fix. I went to my dealer and they wanted to charge me money to fix this issue that has been present but unnoticeable on my vehicle until recently. Not having 12V power to the harness is vary dangerous because if towing a trailer with electric brakes, they will not work, and there is no way to tell this except for using a tester at the harness.

To Whom It May Concern, I am writing to you to emphasize and provide additional details regarding the critical safety issue concerning the Tesla Model X vehicles. My personal experience underscores the severity of this problem: I have had to replace over 8 tires in 3 years due to accelerated inner wall wear. This specific wear pattern is a direct result of improper camber alignment, an issue that Tesla has continuously refused to rectify. This problem is not isolated to my vehicle alone. A growing number of Tesla Model X and Model S owners have reported similar experiences, indicating a widespread and systemic issue. The accelerated inner wall tire wear poses significant safety risks, as it can lead to unexpected and dangerous tire failures on the road, which has happened to me. Very dangerous. Despite the clear evidence and numerous complaints from Tesla owners, Tesla has consistently declined to address this issue adequately. It appears that the company’s reluctance is rooted in the fact that proper repair or recall to fix the camber alignment is not cost-effective from their perspective. However, this cost-cutting measure is putting drivers and passengers at risk. Given the scale and gravity of this issue, I urge the National Highway Safety Institute to take immediate action. It is essential to investigate these recurring problems with both the Tesla Model X and Model S models. The safety of Tesla drivers, passengers, and the general public is at stake, and a thorough investigation could compel Tesla to take the necessary corrective actions. Thank you for your attention to this urgent safety matter. I trust that the National Highway Safety Institute will act promptly to ensure automotive safety and hold manufacturers accountable for their vehicles’ reliability and safety. There have been 4 incidents of this happening with my car. Just putting one date below.

There was a recall on these cars (22V-818) and manufacture said a software update would solve the issue. But the actual issue is the I-shaft, which is not sealed on those cars. Now the manufacture is replacing the I- shaft, with the same issues which they said that was corrected with a software update, by charging customers thousands of dollars with sealed ones. All those cars having the issue which I am facing now. I have escaped a crash narrowly and it is dangerous.

While using Actually Smart Summon to get my Tesla model X out of a parking spot it turned into the car next to mine and proceeded to try exit the space while scraping the doors of the Tesla and bumper of the BMW M5 next to me. Even though I was watching the car I couldn’t stop the crash from happening in time. There was a near miss with another person getting into the car adjacent to the vehicle my car collided with which could have caused serious injury. I also have video of the whole event but can’t upload more than 10MB files, please reach out if you want the video.

To Whom It May Concern, Service bulletin SB-21-39-001 [XXX] ) was issued for the front half shaft repair for model X, S. In my case, the repair work was done but did not address the issue. They only replaced the parts, and after two years the problem still occurs: vibrations at accelerations, etc. I had to pay over $2000 for the same work, which will probably not address the issue in the permanent matter. Tesla, especially, Model Xs has issues with front half shafts, and I want to encourage NHTSA to look into this bulletin and mandate Telsa to repair the vehicle with a more permanent solution and provide reasonable repair costs in doing so.
