Tesla Model 3 stalling problems

Filed Aug 14, 2026 · Driver assistance · AZ

The vehicle is experiencing severe, unpredictable software and hardware regressions related to the Full Self-Driving (Supervised) system (v14.3.7, Software build 2026.21.5) that create an immediate, active traffic hazard and a high risk of rear-end collisions. Primary Safety Issues: 1. TRAFFIC STALLS UPON DISENGAGEMENT: When Full Self-Driving (FSD) is engaged, auxiliary sensors malfunction, causing the headlights to cycle on/off and windshield wipers to run at full speed in clear, dry, midday daylight. When attempting to manually disengage FSD to correct these malfunctioning systems, the vehicle fails to smoothly transition control. Instead, it triggers critical red flashing alert lights, sounds severe warning chimes, and initiates an immediate, aggressive brake application—stopping the vehicle dead in active, live traffic. 2. PHANTOM BRAKING: The vehicle routinely experiences sudden, severe, and unprovoked phantom braking events while driving at speed, without any forward obstacles or environmental hazards present. 3. STEERING INSTABILITY: When navigating parking lot entrances, the vehicle exhibits extreme "indecisive behavior," resulting in violent, rapid shaking of the steering wheel before completing the maneuver. Tesla customer service was formally notified of these dangerous system behaviors on August 14, 2026. A formal remote engineering log review has been requested from the manufacturer, as these sudden braking actions in active traffic pose an immediate threat to public safety.

The vehicle is undriveable due to a high‑voltage enable safety lockout triggered by ECU identity/MAC mismatch after a software/update window; local service instructed me to ‘safely disregard’ active safety alerts contrary to vehicle telemetry, creating a safety risk. Chronology (key timestamps) • Jan 28, 2026 — Low‑voltage undervoltage precondition recorded (DIF_a018). • Feb 2nd, 2026 — Low‑voltage undervoltage precondition recorded (DIF_a018). • Feb 03, 2026 08:46 — Identity/MAC invalidation alerts (CP_a089 / CP_a077); HV‑enable blocked cascade. • Feb 24, 2026 — Service app: estimate approval prompt; supervisor instruction to ‘safely disregard’ active HV alerts captured via screenshot. • Feb 27, 2026 — Persistent handshake stall (CP_a066, State B1) despite ‘successful’ software job and new firmware update to patch the 2026.2 tree branch software. Vehicle remains grounded. Safety Concern Vehicle telemetry states HV contactors are blocked to protect the vehicle; service staff advised to disregard active alerts. Inconsistent guidance risks unsafe operation. I grounded the vehicle pending engineering review. Troubleshooting and A/B Tests My home EVSEs successfully charge a different Tesla (Model Y). The subject VIN charges at DC fast charging (Supercharger) and once on a third‑party EVSE, but fails on my two home EVSEs thereafter. This localizes the issue to vehicle‑side AC charge path/charge‑port logic rather than the EVSE. Request OEM to provide CP waveform under load + Toolbox logs. Please log this safety‑related defect; aggregate with similar complaints, and, if appropriate, open an investigation into identity/integrity faults causing HV‑enable lockouts and conflicting service guidance

The blinkers do not respond to the change in blinkers when I initiate the blinker (right or left) by using the stalk. There has been numerous times that I fully pull down or push up the blinker stall and it would not engage the blinker but today I am reporting it because now I almost changed the lane after engaging the blinker but it didn’t happen

The right and left turn indicator buttons freeze up, and will not operate for indefinite periods. The problem is intermittent, however, the buttons may be frozen for several minutes before the problem clears. I believe the manufacturer is already aware of this problem affecting numerous 2024 model 3 vehicles. I believe this appears as a definite manufacturer design flaw, and does not appear as reasonable user error, or other isolated random defect. The problem is presently becoming well known to 2024 model 3 owners in all markets, and there are now many online posts by other owners of this vehicle model for this identical problem. I encourage the federal safety agency to conduct a quick online search of user reported incidents, as an easy starting point. This problem creates a serious safety risk to other drivers, since other drivers cannot be made aware of affected vehicle's driving intentions. There is no reliable means for affected vehicle drivers to predict or reliably control this problem, that I am aware of. The problem also creates a significant distraction for the driver of the affected vehicle, and particularly in situations that require rapid signal intentions, such as multiple immediate left and right turns in quick succession, or, emergency lane change to avoid stalled vehicles, or, intended driver direction following a four-way stop, etc. This problem may also create a potentially unavoidable legal jeopardy for any affected driver, who may face reasonable driving penalties enforceable by police, or, may be held at fault for accident, despite affected driver's best intentions to use or rely on the faulty equipment. I truly believe this is a serious problem worthy of immediate manufacturer recall and permanent remedy by the manufacturer. It is only a matter of time before a serious accident occurs, resulting in possible injury or death to anyone who either drives, or encounters, an affected vehicle. I hope the federal safety agency will promptly investigate. Thank you.

Tesla vehicles do not have “Trailer Mode” available when aftermarket trailer options exist. Tesla only installs this required software when the towing hitch option is installed from the factory. When U-Hual or other services install aftermarket towing capabilities, Tesla does not add this necessary software package which is required for the safe operation of the vehicle when towing. This applies to the Model 3 and Model Y. The trailering mode software does the following: - Disables autopilot when trailering or towing. - Traffic aware cruise control increases the following distance for a safe stopping distance. - Side collision warnings are active which automatic steering interventions are disabled. - Collision Avoidance assistance is modified to accommodate the trailer and trailer weight. - EV Supercharger navigation only routes through “pull through” / “trailer capable” charging stalls. - Trailer sway mitigation. The vehicle’s stability control system maintains traction and stability and accommodates for the trailer sway/weight. (I may be missing some stuff but this is the most complete list I could find). Again, Tesla only adds this software to vehicles that get a hitch from the factory. If you have a U-Haul Hitch or other installed hitch on the Model 3 / Y, Tesla does not add this software. The easiest and most cost effective way to fix this would be to require Tesla to include the trailering mode software on all vehicles by default through a recall update.

Vehicle touch screen will shut off while driving and take 5 minutes to reboot. I have taken it to Tesla multiple times since November and they said it’s a firmware issue and nothing is being done to resolve.

Drive Unit inverter failed. Yes my safety and the safety of my passenger and drivers behind me was at risk Problem was confirmed by Tesla repair center. They diagnosed this as the problem. No accident happened so no police, insurance reps, etc. Warning lamps came up after the car stalled. Or at least that's when I noticed them. while I was driving the car started jerking and came to a complete stop in traffic. No warning, just stopped. It wouldn't start or roll or anything and I was blocking traffic until I could get Tesla Roadside service to tell me on the phone how to put it into Transport Mode to push it to the side. This took 2 hours. My safety was DEFINITELY at risk. If I had been travelling at a high speed, it could have been fatal. The dealer/service center said it's the failure of the rear drive unit inverter and it was a US made part by Tesla. Warnings showed up on the screen but after the call stalled. It is currently at the dealership being replaced but now I am afraid to drive it as I have lost confidence in the company. I really hope you put pressure on Tesla to correct this problem. It is terrifying.
