2024 Tesla Model 3 acceleration problems

Filed Oct 20, 2026 · Acceleration, Electrical · FL

On October 16, 2026, my 2024 Tesla Model 3 initiated a standard, factory-prompted over-the-air (OTA) firmware update. During this automated install process, the car's firmware crashed. Following the crash, the vehicle was left unresponsive. Tesla Service conducted a diagnostic review and isolated the problem to a physical failure of the internal hardware: Assembly - Power Conversion System - 48Amp - 1Phase. The vehicle was performing flawlessly and charging efficiently prior to the software update execution. The PCS module did not break due to driver abuse, mechanical wear, environmental damage, or physical aging. It failed strictly because Tesla’s proprietary software update process overtaxed, corrupted, or bricked the internal semiconductor boards during a forced rewrite command. A consumer should not be financially penalized for hardware damage caused by a manufacturer's remote software push.

While turning right, I slowed down and put on my turn lights. The vehicle accelerated all of a sudden and did a sharp right. There was a vehicle in front of me in the opposite direction and my car turned very sharply to avoid it. The accelerator pedal was fully pressed down and for that fraction of a second, it didn’t allow me to control the speed.

Component/system that failed: Tesla Full Self-Driving (Supervised) software version 14.x (2025.38.x and later). The issue is software-only and remains installed on any vehicle updated to v14. Description of safety defect: FSD v14 deliberately removes the driver’s ability to set or adjust maximum speed offset using the right scroll wheel (feature present in all prior versions including my current v13.2.9). As a result, the system routinely exceeds posted speed limits by 5–20 mph with no way for the supervised driver to correct it short of fully disengaging FSD. The vehicle ignores speed-limit signs, relies on inaccurate map data, and follows surrounding traffic speed instead of the legal limit, even in school zones, construction zones, residential areas, and adverse weather. This significantly increases risk of collision, injury, and traffic citations. Reproduced/confirmed: Widely reproduced by thousands of owners on Tesla forums, Reddit, and X immediately after v14 rollout in late 2025. I have chosen to remain on v13.2.9 to avoid this exact defect. Inspected by manufacturer or others: No in-person inspection required; Tesla has full remote log access. Multiple owners have submitted in-car bug reports. Warning lamps/messages: None. The speed-offset control is simply grayed out and non-functional by design in v14. Vehicle available for inspection upon request.

Full self drive 14.1 removes the max speed setting that allows drivers to control the speed of the vehicle while under computer control, leaving no way to prevent the car from speeding when the speed profiles choose to drive over 28+ mph over the speed limit. The lack of ability to control the speed of the system is fundamentally unsafe by design.

I was in a drive thru of a fast food restaurant and the car rapidly accelerated on its own and crashed into a wall. The air bags deployed and we were injured. We also narrowly missed hitting a pedestrian. The car hasn’t been inspected by anyone yet, however it is available if someone wants to inspect it.

This is the 3rd or 4th time I have observed sudden unexpected acceleration when at a full stop at a light while using FSD Supervised (v13.2.7 just updated). It first happened 2 or 3 times on FSD v13.2.6 when mine was the lead car at stop lights. This time I was at a stop light but obviously not the lead car. The truck in front of me was blocking view of the traffic lights. Each time, I have hit the brakes immediately, so I don't know if the vehicle would stop on its own during these situations, but I have no issues with it safely braking at any other time. Other than this intermittent glitch, FSD has been flawless on the HW4 next generation computer, which may lead to driver complacency not expecting this. I am reporting for awareness & hopefully correction. I have MP4 video files of the incident, but I cannot upload them here.

the car consistently has phantom braking. the speed will drop around 15 miles of speed immediately. it also will slow on rolling hills and random long turns on cruise control. most recent date listed
