2022 Tesla Model 3 lane departure problems

“There are hundreds of reports regarding Tesla HW3 computers overheating following the software update to Full Self-Driving (FSD) Lite V14. On 19 SEP 2026, I was required to replace the HW3 computer on my 2022 Model 3 Performance; the total price was approximately ($2,700.00). As the computer was perpetually stuck in a reboot status, the car's safety and security systems weren't functioning properly (e.g. forward collision assist, lane-keeping assist, cameras, Sentry Mode, etc.). Additionally, while parked overnight, the car drained 2-3 times more power as the computer remained stuck in the reboot loop. The computer clearly failed following a software update that increased the performance outside of the design tolerances. However, because my vehicle was out off warranty (both years and mileage), Tesla required me to pay out of pocket for the repair as it was deemed to be normal wear & tear. Of note, we bought the vehicle brand new in June 2022 and it had 62,652 miles at the time that the computer was replaced; Tesla's New Vehicle Limited Warranty is 4 years / 50K miles. I, like many other owners across multiple forums, believe that Tesla needs to take…”

“Vehicle was operating under Tesla Full Self-Driving (Supervised) on [XXX], on [XXX]. While FSD was engaged, the vehicle struck a large object/debris that was present in the travel lane. The system did not appear to detect or avoid the obstacle. The impact caused severe damage to two wheels and two tires, and the vehicle required towing. Tesla Service later confirmed that the damage was caused by road debris and replaced the damaged wheels and tires. I am submitting this report because I am concerned that the FSD system failed to identify or respond to a significant roadway hazard.”

“I purchased the Full Self-Driving (FSD) package for approximately $10,000 on my 2022 Tesla Model 3 Long Range AWD. Tesla marketed FSD as a feature that would enable autonomous driving capabilities including Navigate on Autopilot, Auto Lane Change, Autopark, Summon, and city street driving - all to be delivered via software updates. Tesla has since confirmed my vehicle's HW3 (Hardware 3.0) computer cannot support FSD as advertised. There is no hardware upgrade path. The FSD Transfer Program that allowed owners to move their purchase to a new vehicle ended March 31, 2026 with no accommodation for affected owners. The system regularly fails to perform as advertised. It requires constant human supervision despite being sold as "Full Self-Driving." I have sent three formal complaints to Tesla's executive team (May 7, 8, and 12, 2026) with zero response. Tesla's own support chatbot confirmed I am not eligible for FSD transfer.”

“While using Tesla's Full Self-Driving (Supervised) software on the Pacific Coast Highway (PCH) and other highways, the vehicle’s automated steering system repeatedly malfunctions by failing to maintain lane centering. Specifically, the car drifts or actively steers across double yellow lines into the lane of oncoming traffic. This issue is a persistent failure of the Advanced Driver Assistance System (ADAS) and Lane Keeping Assistance. The vehicle has attempted this maneuver multiple times at [Approximate Speed, e.g., 40-60 mph], requiring immediate and forceful manual steering intervention to avoid head-on collisions with oncoming vehicles. The system provides no warning chimes, error messages, or "Take Over Immediately" alerts prior to crossing the lines; it appears to perceive the oncoming lane as a valid path or fails to recognize the double yellow boundary entirely. This has occurred during [mention conditions: e.g., bright daylight with high glare / night time]. The vehicle is equipped with Hardware 3.0 (HW3). I believe the 1.2-megapixel camera suite or the processing power of the HW3 computer is insufficient to safely navigate the geometry of the PCH or…”

“teslas have blind spot monitor cameras that activate when the turn signal is activated as a turn left or right. there seems to be a noticeable delay on older cars with intel processors where the cameras take longer to display on the screen in split second manuvers and lane changes that can lead to accidents”

“The central computer in my 2022 Tesla Model 3 failed unexpectedly. This is a critical component that controls essential vehicle functions, including safety alerts, battery management, regenerative braking, Autopilot features, navigation, and over-the-air updates. The failure makes the vehicle unsafe to operate. The car is only 2–3 years old, and such a major systems failure in such a short time frame suggests a defect or premature failure in a component that is expected to last the life of the vehicle. Tesla has not offered a remedy despite this being a safety-critical system. I believe this failure presents a serious safety risk to myself and others on the road and should be investigated.”
