2022 Tesla Model Y electrical system problems

“The contact owned a 2022 Tesla Model Y. The contact stated that while driving at an undisclosed speed, the central computer suddenly overheated. The failure caused the vehicle to stop immediately and disabled other essential safety features. During the failure, the center screen flashed red with a message instructing the driver to take control, followed by a series of unknown error codes and an "APP_W141 ECU thermal alert" warning. After researching, the contact discovered that the failure might have been caused by a recent software update from the manufacturer. The manufacturer was notified of the failure, and a Tesla Service Center confirmed the failure as a Hardware 3 computer failure. The contact was informed that the system needed to be replaced. The failure mileage was 95,000.”

“At only 27k miles in with no accident history and perfect maintenance my camera system began to fail. It started with a delay of the backup camera and then turned into the cameras no longer working and no longer talking to the satellites. This then became a gps issue. Tesla despite me being 1 month outside warranty and well below the mileage charged me for a 4k new computer without diagnosing the failure as to whether it was heat related or what. It said the FSD computer was failing to make connection with the other computer. I had never even used FSD. This Premature failure of the computer system should’ve never been charged to me.”

“On Aug. 9, 2026, my 2022 Tesla Model Y experienced a sudden low-voltage electrical failure that completely immobilized the vehicle. Earlier that morning, the Tesla app sent a push notification indicating low-voltage battery service was needed. I tapped it, but it provided no actionable warning. I immediately checked Maintenance. At 9:06 AM, the app displayed “0 Recommended” and “No maintenance is recommended for your vehicle at this time.” Less than an hour later, the vehicle completely failed. Nothing functioned. We could not open the doors or trunk, access the vehicle normally, or operate vehicle functions. The vehicle could not be put into a condition for normal towing; it would have had to be dragged/pulled onto the tow truck. Tesla later documented “Electrical system is unable to support all features” and is replacing the 12V battery. This may be relevant to NHTSA PE25010.”

“Tesla released a new version of FSD: 2026.20.6.11 V14 Lite for my 2022 Model Y Long Range. I installed it overnight and the next morning, several systems become intermittent. The backup camera stopped working immediately, and FSD would drop out, with the message "Take control immediately". I would then lose traffic visualization and other advanced features. Eventually the system would recover and start the cycle all over again. Several times per drive. I took the car to the dealer and they diagnosed it as a failed HW3 computer. The cost to repair it was $2,939 out of pocket since my car was 2 months out of warranty. The car was 100% functional before the V14 Lite update. The dealership denied the problem was related to the update, but the internet now has numerous instances of this problem, and attribute it to the computer running much hotter under this new update, causing components to fail. Our update was installed while the car was in our garage at a temperature in the 70’sF and immediately caused the computer failure before the car even left the garage. I requested and was given the failed computer in case any independent investigation is needed”

“While operating my 2022 tesla model y, the vehicle suffered a catastrophic hardware failure of the onboard vehicle control computer. This total computer failure resulted in an immediate, sudden loss of electronic power steering assist while the vehicle was in motion. The steering wheel became incredibly stiff and heavy, creating a severe and hazarders driving situation. the vehicle was towed to a tesla service center, where technicians confirmed the onboard computer hardware requires a complete replacement. A vital computer failing prematurely on a 2022 vehicle presents an extreme safety risk of crash or injury due to sudden loss of vehicle control.”

“The contact owns a 2022 Tesla Model Y. The contact stated that while the vehicle was operating in the self-driving feature, the vehicle bumped into a shopping cart holder while attempting to park into a parking space, prompting the contact to take control of the vehicle. The rear bumper on the driver's side was impacted. No property damage was reported. The vehicle came to a complete stop upon impact. No air bag was deployed. There was no warning light illuminated. A Police report was not filed. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 32,074.”
