Tesla Model Y stalling problems

Filed Oct 4, 2026 · Driver assistance, Electrical · PA

COMPONENT: The car computer (Tesla HW3 / "Full Self-Driving Computer 3," which houses the Autopilot computer and GPS) failed during a scheduled overnight over-the-air software update from version XXX in early XXX. The update failed to install, and from that point all cameras were black including the backup camera, navigation was frozen, and every driver-assistance feature was unavailable: Autopilot, FSD, automatic emergency braking, forward collision warning, lane keeping, and blind spot monitoring. The failed unit was returned to the owner and is available for inspection. SAFETY RISK: The vehicle remained drivable with crash-avoidance systems and the federally required backup camera disabled. The only indication was a camera-unavailable message; there was no clear warning that AEB and collision warning were off. The vehicle was driven about three weeks in this condition while awaiting parts. CONFIRMED BY MANUFACTURER: Yes. Tesla remote diagnosis determined the car computer required replacement. Tesla remotely cancelled and re-pushed the update on XXX; the download stalled at 0 B/s and never installed. Tesla Service in [XXX] replaced the car computer on XXX at owner expense ($2,489.48; outside basic warranty, goodwill declined). Tesla's repair notes state the loss of all camera images and Autopilot capability occurred "after a failed software update." PRIOR WARNINGS: None. No warning lamps or messages before the update; the vehicle operated normally on XXX Owner resets, power-off, and 12V disconnect did not restore function. ASSESSMENT: The Autopilot computer failed during a manufacturer-pushed software update. Owner forums and automotive press reported numerous similar HW3 computer failures in summer 2026 following Tesla software releases. No crash, fire, or injury.

The vehicle made contact with other vehicles twice within a short period while Full Self-Driving (Supervised) was engaged, and it did not respond to my attempts to intervene. On XXX, at approximately 1:30 PM, in the Stanford Oval parking area in [XXX], I was using Tesla Full Self-Driving (Supervised) in my brand-new 2026 Tesla Model Y when the vehicle began a reversing maneuver between two parked vehicles. During the maneuver, the on-screen visualization continued to show space between my vehicle and the surrounding vehicles. The vehicle then made physical contact with another vehicle. I received no proximity or collision alert, and the display continued to show clearance after contact occurred. After contact, the vehicle continued attempting to reverse, stalled, and behaved erratically. I attempted to brake and disengage the system, but the vehicle kept glitching and moving backward. I could feel resistance while trying to control the vehicle.Shortly afterward, at [XXX], the vehicle showed substantially similar behavior and again made contact with another vehicle. My vehicle sustained damage to the rear bumper and lights. The other vehicle had pre-existing damage, and its driver told me she did not want to pursue anything or have her vehicle repaired. The vehicle is brand new and I had no prior accidents. I will be assessing myself for injuries. I reported the incident to Tesla.

On July 10, 2026, my 2024 Tesla Model Y (approx. 22,440 miles) lost all power (main/12V battery) while parked next to a Supercharger stall on Level 3 of the Harrah's Ak-Chin Casino parking garage, Maricopa, AZ. Ambient temperature was approximately 110F. My dog and cat were inside the vehicle. With the vehicle powered off, the key card, Tesla app, and interior door releases did not function, leaving no way to open the doors from outside or inside. Unable to find or access a working manual door release in time, we broke the rear quarter glass and damaged a door to physically extract the pets before they suffered heat-related harm. Maricopa Police Department and Ak-Chin Fire Department responded to the scene. This represents a serious safety defect: a loss of vehicle power should not eliminate all means of entry/egress, particularly when children or pets could be trapped in extreme heat. The vehicle, damaged door, and glass are available for inspection. Photos of the incident are available.

In approximately August 2023 — approximately seven months after purchase — the vehicle’s battery stalled completely while I was driving a few miles from my house on a surface road. The vehicle lost all drive power without warning. I was fortunate that no vehicle was following me or they might have slammed into the vehicle’s rear if they were unable to suddenly quickly stop. I turned on the emergency flasher lights, and after waiting a few minutes, the vehicle restarted and I decided to just drive the car home. I did not continue on my planned destination.

The headlights turned off while driving. Not being able to see where you're going is risky. The problem has occurred twice under the same conditions - light snow covering on the car. It has not been reproduced at dealer or service center. Components have not been inspected. The headlights operate properly when the snow is removed. No warning, messages or symptoms. Tesla Assist states that if there if driving in snow or low viz conditions, the headlights should be turned on manually, which is not intuitive or appropriate given the advanced nature of the car

In May 2025, Tesla pushed an over-the-air (OTA) software update overnight while the vehicle was parked. When the vehicle was started the following morning, the update had failed mid-process and stalled at approximately 50%. Immediately upon startup, the backup camera and navigation/maps stopped functioning. The vehicle has been unable to complete subsequent software updates since. Tesla service later inspected the vehicle and indicated that the main computer/ECU was stuck in a loop and required replacement. The backup camera and navigation loss occurred immediately following the OTA update and persisted for several months despite multiple service attempts. Due to the vehicle’s rear design and limited rear window visibility, operating the vehicle in reverse without a functioning backup camera significantly impairs visibility. Even when using mirrors or physically turning to look backward, rearward visibility is restricted. As a result, the loss of backup camera functionality presents an ongoing, daily safety hazard during normal vehicle operation.

While backing out of a parking stall, the bolts securing the front right lower control arm fell off. One of the bolts rolled under the car and the other bolt was still in the control arm. This vehicle has never been off road, or in an accident. It was towed to the dealership for repairs. It terrifies me to consider what would have happened to me or my family had the bolts fallen off driving at freeway speeds. "Tesla Technician Notes: The customer reported that the lower front control arm fell off, which was verified by inspection showing extensive damage to the suspension, subframe, and front drive unit. The issue was caused by both bolts falling out of the right front lower lateral link. To address this, technicians replaced the front lower lateral and compliance links, steering rack, RF spring and damper assembly, subframe, drive unit, RF halfshaft, RF wheel arch liner, stabilizer bar links, and aero shield, and performed a four-wheel alignment check and adjust. The repair was validated by ensuring all components were securely reattached and functioning properly."

Vehicle was performing normally until I stopped and put vehicle into reverse to back into a supercharger stall. Heard a clunk when starting to back up. Car started to resist moving and front started to lift in the air a few inches. Stopped and went forward to go around and try again. Vehicle would not turn to left when going forward. Got out and noticed front passenger wheel was not aligned with other front wheel. Then noticed tie rod was ripped out of socket.
