2017 Tesla Model X Electrical System Problems

High voltage battery management system generated fault codes BMS_u008 and BMS_f071 during a Supercharger charging session, prohibiting drive mode. Vehicle had been driven normally to the Supercharger with no drive-prohibiting alerts during transit. After connecting to the Supercharger, fault codes manifested. Despite fault condition, vehicle continued charging to 93% state of charge before requiring towing. This is the second such event — original HV battery also generated BMS fault alerts prohibiting drive mode during a charging session in January 2024 and was replaced with a remanufactured assembly. Third-party firmware alert data shows recurring hardware charging fault alerts (CHG_f018, CHG_f076, customer message: Unable to charge) occurring in January and February 2026, weeks prior to the March 2026 failure. Alert DI_u014 also fired repeatedly on March 18, 2026 indicating insufficient 12V supply contributing to undriveable condition — a separate system from the HV battery. Tesla Service Center has not investigated whether Supercharger charging events contributed to either failure, has not produced Supercharger session logs, and has not attempted software-level fault resolution before recommending full hardware replacement. Tesla's own firmware documentation describes BMS_u008 as potentially self-clearing and BMS_f071 as having a documented clear condition. Remanufactured battery subsequently drained from 88% to 0% over 11 days while unplugged at service center — 6-9% per day versus normal 1-3% per day vampire drain, consistent with active BMS fault causing abnormal parasitic draw.

During home charging using 40A, the 220 volt UMC connector started smoking and was melting. The charging appeared unaffected, and I caught it before it caught fire.

April 2024: Tesla Model X repeatedly failed to download firmware updates, although offered via the car’s UI. The car uses the connected WiFi to download several gigabytes of data every month, but ultimately does not apply any updates. This is a serious safety issue, since it prevents all future software update recalls from being available to this vehicle. May 15, 2024: Tesla failed to fix this issue through remote diagnosis, and requested a service center visit. Tesla engineers diagnosed the vehicle at the Burlingame CA Service Center, and spoke to me on the phone that the root cause was a recent firmware upgrade that has permanently bricked the ECU unit, which now needs to be replaced. Since this ECU unit is not user-accessible or user-serviceable, there is no way for this to have been caused by the customer. Tesla quoted $2048 to fix it, out of pocket, even though this damage was not caused by the customer, or related to regular wear-and-tear, but (as acknowledged by Tesla) caused due to a faulty firmware update issued by Tesla themselves. May 17, 2024: After pointing this out to them, Tesla managers called me, offering to discount the repair by 25%. Many similar complaints about the exact same part (ECU unit) and the same mode of failure (bricked after buggy firmware update) can be found shared online by others. This is a systemic issue, and not a one-off failure for my car alone. [XXX] [XXX] [XXX] All I am requesting is that Tesla fix this issue at their own cost and make my purchase whole, but Tesla has not honored that request so far. Thank you!

The component that is not working on my car is the intermittent windshield wipers. The issue is that the intermittent wipers do not come on in eaither of the 2 low settings. The wipers only work in the steady low and high settings. When it is just misty out or a light rain, you have to manually push the button at the end of the stalk to give a swish of the wipers. If you are on the steady low setting, it is too much and the wipers squeak on the widsheild. I originally brought this into my Tesla service center in October and they told me that this would be fixed in a firmware update. I have followed up a few times as the update never came and today I am back at the service center and they have told me that they are still waiting for this problem to be addressed and that I should just use the other low and high speed wipers to clear the mist. It is now the end of December, almost 3 month later.This is not safe and should be addressed right away.

Manufacturer designed a Pyro Fuse (a/k/a Battery Fuse), the purpose of which is to open the main battery's circuit in the event of a detected crash via a squib charge, in order to prevent further property damage or risk to life. The obsolete design contained in this model depends on a small lithium ion battery with a 7-10 year lifespan. In this car's case, a timer notification kicked in at about 6.5 years of life. The risk to not recalling this part with the new part design (self-charging from the current) and all affected models in the fleet is that now all these vehicles risk higher odds of a catastrophic battery fires during collisions and other failures the fuse was designed to prevent.

The contact owns a 2017 Tesla Model X. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving at an undisclosed speed with the Autonomous Self-Driving mode activated, the Auto-steer feature was engaged, and the vehicle inadvertently steered into the left lane of oncoming traffic. The contact manually steered the vehicle away from the oncoming traffic. An unknown dealer was made aware of the failure but confirmed that parts were not yet available. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure but confirmed that parts were not yet available. The failure mileage was approximately 110,000.

This contains new information, a smoking gun, and is associated with NHTSA complaint numbers 11505487, 11505488, and 11505489. NHTSA Recall: 21V-035; Tesla Manufacturer Recall: SB-21-21-001 I was threatened a $35/day charge and tow/impound though no maintenance was performed on my vehicle. I went to pick it up and the vehicle was still suffering from the recalled eMMC issue which causes the screens to blank, freeze, etc. All driving information, safety features, and some exterior safety features are lost - it's a major hazard. This recall has two parts, the first part was a Tesla over the air update, which it pushed to the affected vehicles. I believe in doing this, Tesla has now stated to the NHTSA that the recall was complete. However, the recall has a secondary part "To be specific, Tesla will replace the VCM daughterboard that has the Hynix 8GB eMMC with a VCM daughterboard that has an enhanced 64GB Micron eMMC, free of charge." which Tesla is completely denying accomplishment. I have requested the car be repaired 7 times over the past 6 months and they have denied and avoided the recall repair, stating that there are no active recalls and forcing a paid upgrade to the MCU2. Tesla is abusing the over the air update capability and falsely stating that they're correcting issues to avoid correcting safety hazards. My vehicle has experienced 13 failures over our 6k miles of ownership in 6 months. In those 13 failures, 6 nearly caused catastrophic accidents. Additionally, the service center in Fort Worth (275 University Drive) has been altering/cancelling service records to avoid completing required recall repairs. The GM, [XXX] was recently fired/resigned and the senior service rep [XXX] was moved. Tesla must fix its unsafe vehicles and I recommend double checking all recalls Tesla has "completed" via over the air updates. They're artificially avoiding accomplishment of the recall and leveraging the safety hazard on the consumer. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

Dashboard or driver screen suddenly goes black while driving (and at other times will freeze on a certain speed, despite slowing down, or breaking.) At this point, driver does not know what speed he, or she is traveling at, nor what gear. Response from Tesla is to reboot the car. However, these episodes while driving continue and are very dangerous. Tesla is pushing paying $2000 to get an infotainment upgrade to solve this safety issue which seems to be a defect in the car.

Car was hit by a city bus on 12/17/22. Car was towed to repair shop. Damages were repaired. Shortly after repair, the Car started making high pitched loud sound when a/c turned on. Took the car back to repair shop. Diagnosis: Air conditioning unit and compressor failed. Tesla wants $5700 to fix it, $4444 of it labor charges. They are saying it did not have to do with accident. The car did not make this sound before the accident. See pics.

Original infotainment MCU1 with upgraded memory continues to not allow service mode to initialize. Also screen goes black with no connectivity to the car from my phone app, no access to temperature control, or GPS mapping. No access to any seat controls or door controls. This occurred for 1 hour while driving to home. System is operational again - 10 days later with no driving in between. Tesla service came out to diagnose and are not sure of the cause, however failure cause safety issues for passenger overheating and control functions to operate the car as well as diagnose the issue.

The contact owns a 2017 Tesla Model X. The contact stated that the message "Air Suspension" was displayed intermittently while driving. The vehicle was taken to the Tesla Service Center where it was diagnosed that no issues were found. The contact stated while her fiancé was pulling into a parking lot at 5 MPH with her in the front passenger’s side seat, the vehicle lunged forward and shut off inadvertently. The contact and her fiancé were unable to restart the vehicle, to turn on the hazard light. Additionally, they were unable to open the driver’s or passenger’s side doors. Additionally, the contact stated that the passengers occupying the second and third-row seats including her disabled father were also unable to open the rear doors. The contact stated that the vehicle was becoming increasingly hot. The contact and some of the passengers crawled to the rear seats and removed both the rear driver's side and the passenger's side door panels in order to access the emergency releases. The contact stated that one person pushed the rear door from the inside while another person was pulling the rear door from the outside and the door opened. The contact and the other passengers were able to exit the vehicle. The manufacturer was notified of the failure but was unable to access the computer system. The manufacturer advised the contact to tow the vehicle. The vehicle was towed to a Tesla Service Center where it was still being diagnosed. The vehicle was not repaired. The failure mileage was approximately 93,000.

MCU failure. Same symptoms as a failure of the mcu1, although mine was upgraded over a year ago to mcu2. It has failed. Failed strangely enough, after leaving the dealership, after an unnecessary recall to update MCU memory. My car does not have the problem. I was told, and given the car back. a mile from the dealership I realized that nothing was working. Can not turn on the defroster cannot operate any other features, air-conditioning, etc. it took three months to get the car back to them to try to address this problem all the time not having a fully functioning touchscreen and after two week time at the dealership they tell me that the MCU has failed and then I have to pay almost $2000 to fix it, additionally, they also said that this is the first MCU upgrade to the MCU to that they have seen fail, which brings up a whole lot more question. Carl was working fine when it entered the dealership to perform this unnecessary repair, but was not working when it left.

. December 2021, I stopped car at traffic light in Stevenson Ranch, CA 91381. Light turn blue but the car can’t start, key fob and tesla app not working. I restarted my phone then Tesla app working back. Took more than 10 minutes. . January 2022, I stopped at traffic light on Siarra Highway, Santa Clarita CA 91351. Light turn blue but car can’t start, key fob and tesla app not working. I have to restarted my phone in order for Tesla app working back. Took more than 10 minutes. We just had a new born so we feel very unsafe with this vehicle. And Tesla just ignore this matter. . 1 time car not working in garage for more than 24 hours so I called Tesla Roadside Assistant to tow to Tesla dealership. All they done was replaced key fob battery even I had mentioned about the incidents above. . Many times that car just close the door by itself ( left front driver, left and right falcon door, trunk ). Yesterday February 17th I was in Van Nuy CA ( 99 Ranch market loading groceries in to car ) trunk close bump on my head.

Screen goes blank from time to time. Takes a long time for the car to power on.

Manufacturer Recall NumberSB2121001 NHTSA Recall Number21V035 For the above recall numbers - I contacted Tesla shortly after I became aware of the recalls. I was told that they would reach out to me within 6-8 weeks to schedule the repair. To date, no Tesla Advisor has contacted me to schedule a repair. Subsquent follow ups, various Tesla staff tell us different remedies, incuding some Tesla staff that tell us a recall is no longer required due to an OTA firmware update. However, issues with the emmc continue to happen (losing the main screen, random freezes/reboots while driving, and turn signals not operating intermittently when the screen is frozen) and the recall language seems to indicate that a physical repair is still needed. Thanks for your assistance and all you do.

Our SUV lost power in the middle of the highway with no warning. After a month of back and forth, Tesla is saying that the High Voltage Battery needs to be replaced. The car has been with Tesla Marietta, GA center waiting for the replacement part with no ETA. How long are we supposed to allow the manufacturer to address the problem per the manufacturer warranty.

The contact owns a 2017 Tesla Model X. The contact stated while driving at various speeds, both center display screens turned off inadvertently. There was no warning light illuminated. The vehicle was taken to a local Tesla Service Center where the computer software was updated and reset however, the failure reoccurred. The vehicle was taken back to the local Tesla Service Center where it was diagnosed that both center display screens needed to be replaced. The center display screens were replaced; however, the failure persisted. The vehicle was taken back to the Tesla Service Center where it was diagnosed that the center displays needed to be replaced with upgraded parts. The contact stated that he was informed that the repair would not be covered under warranty. The vehicle was not repaired. The failure mileage was approximately 26,000.
