I was on the exit lane coming from Costco on 12/31/2022 at around 12:20 PM with a speed of about 40 miles . My exit is about 100 yards away. Tesla model 3 that I’m driving suddenly accelerated at high speed and pulled towards right and hit the wall next to freeway exit lane. Then it hit the wall on rear tailgate and rolled to middle of freeway within a fraction of seconds. Two vehicles coming on…

What stands out
Owners have filed 59 cruise control complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA cruise control complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners describe recurring phantom braking: vehicle suddenly applies hard brakes dropping speed 15–50 mph in seconds with no visible road hazard, vehicle, or traffic ahead. These events occur on clear, sunny, divided highways at speeds 65–80 mph, often multiple times per trip. One owner documented 40 phantom braking events over a week; others report events every 10 minutes to every 2–3 hours of highway driving. Some owners see phantom objects briefly flash on the traffic display screen before braking. A few mention heat mirages on pavement or reflections triggering events, and some report worsening frequency after recent software updates.
Unintended acceleration at low speed is a separate pattern: vehicle surges forward while parking, approaching stop signs, or in stop-and-go traffic. Crashes documented include hitting garages, parked vehicles, pedestrians, and other cars—with airbag deployment in some cases. One owner reports being unable to stop the vehicle with brakes after unintended acceleration began.
Additional complaints cite cruise control that won't disengage when driver applies brake or stalk command, autopilot that misreads traffic lights and moves at red lights, and adaptive cruise that ignores speed limit decreases. One owner reports the system frozen entirely, screen going black, with normal function restored only after a reset.
Tesla service remotely diagnoses "no hardware issues" and declines to inspect vehicles or review dashcam footage, despite owner confidence these are genuine malfunctions, not driver error.

Failure modes owners describe
Phantom braking under cruise control / TACC
Vehicle applies sudden, hard braking with no apparent road hazard, vehicle, or obstacle ahead. Owners report speed drops of 15–50 mph in seconds. Events often occur on clear highways in daylight with no traffic, sometimes multiple times per trip. System does not provide warning before or after braking.
When: On highway/interstate use; some owners report worsening after OTA updates; occurs at speeds 65–80 mph; one owner noted worse at night
Symptoms owners cite: Sudden hard braking dropping speed 15–50 mph in seconds; No warning lights, messages, or alarm; Vehicle lurches forward; passengers thrown toward dashboard; Occurs on clear roads with no traffic ahead; Sometimes near overpasses, bridges, or heat mirages on pavement; Phantom objects appear briefly on traffic display screen before braking; More frequent with later software versions per some owners
Repairs/costs cited: Tesla service reports remote diagnostics show no hardware issues; service declines to perform repairs; one owner reports dashcam footage provided but Tesla refused to review; owners report disabling safety systems or avoiding cruise control entirely
Recalls/TSBs owners mention: Tesla remote diagnostics claim hardware is operating as expected and no repairs can be made; claims system is working fine; some owners told problem is caused by curves, off-ramps, or bridges when none are present
Unintended acceleration at low speed (parking, stop-and-go)
Vehicle accelerates without driver input while parking, approaching stop signs, or in stop-and-go traffic. Owners report car surging forward at low speeds (5–40 mph), resulting in collisions with other vehicles, structures, or property.
When: While parking, leaving garage, approaching stop signs, in stop-and-go traffic, at low speeds (5–40 mph)
Symptoms owners cite: Sudden acceleration without pedal input; Car lurches forward uncontrollably; Driver cannot stop car even with brake pedal depressed (one report); Airbags deploy in some incidents; Door locks may not release after collision; Crashes into parked vehicles, structures, or moving vehicles
Repairs/costs cited: One owner reports hitting garage door, neighbor's cars, and curb; hit curb to force stop because brakes not working; another hit truck in parking lot; another hit pedestrian and vehicle at 25 mph; one report of collision at stop sign; one hit wall on freeway exit at ~40 mph; one hit rear of parked truck while parking; one hit rear of pickup truck at stop sign; vehicle was towed or deemed total loss in several cases
Recalls/TSBs owners mention: Tesla manufacturer notified but informed owners no recall under VIN; remote diagnostic performed but results not disclosed; no recall; Tesla blamed user error in one case
Cruise control does not disengage or becomes stuck
Cruise control fails to turn off when driver attempts to cancel it, or engages unintentionally when shifting into Drive. Vehicle remains locked at cruise speed even when accelerator/brake pedals are released.
When: After engaging cruise control; immediately after shifting into Drive
Symptoms owners cite: Brake pedal does not disengage cruise control; Stalk commands do not disengage cruise control; Cruise control engages automatically when shifting into Drive; Computer appears frozen; screen goes black; Turning signals do not function; Car maintains set speed even after releasing accelerator
Repairs/costs cited: One owner reported pressing brake did not disengage, pressing stalk did not work; driver could manually control speed with pedals but after releasing car continued at set speed; system eventually reset and functions returned; one owner states cruise engages unintentionally when shifting into Drive multiple times since purchase
Autopilot / FSD misinterprets traffic lights and road conditions
Autopilot and FSD fail to read traffic signals correctly, moving forward at red lights or misinterpreting lane markings and road geometry. Vehicle merges incorrectly, veers into wrong lane/shoulder, or makes unintended turns.
When: While stopped at traffic lights; while lane-keeping with autopilot; on turns; on navigation routes
Symptoms owners cite: Vehicle moves forward at red light as if light turned green; Merges into left-turn lane unintentionally when signaling to change lane; Veers right onto shoulder on left turns; veers left onto shoulder on right turns; Approaches corner and speeds up before sharp turn; Overshoots white line when coming to stop; Takes turn at last minute causing items to fly; Turns into dead end instead of correct route on navigation; Slow acceleration from green light even with no car ahead
Adaptive cruise control exceeds speed limit
Adaptive cruise control / Autopilot does not obey posted speed limit changes. Vehicle maintains previous speed or exceeds new speed limit despite correct speed limit displayed on vehicle.
When: When speed limit decreases after highway speed zone
Symptoms owners cite: Vehicle does not slow when speed limit decreases from 70 mph to 60 mph; Car exceeds posted speed limit despite setting all available controls to obey speed limit; Correct speed limit is displayed on vehicle but not followed
Cruise control features disable frequently
Emergency automatic brake, cruise control, and autopilot features disable simultaneously and repeatedly. Service reports unable to diagnose root cause.
When: Intermittent; all three features disable at same time
Symptoms owners cite: Emergency automatic brake disables; Cruise control disables; Autopilot disables; All three disable simultaneously; Issue recurs
Repairs/costs cited: Service center advises firmware update needed; no estimated time to fix; service claims vehicle is safe to drive despite failures
Recalls/TSBs owners mention: Tesla service unable to find problem; engineers investigating; firmware update pending
Emergency braking applied incorrectly during normal driving
Forward collision warning and emergency braking systems trigger without hazard present. Vehicle applies emergency brake in stop-and-go traffic when traffic clears and moves normally.
When: In stop-and-go traffic when traffic begins moving at 5–10 mph; without autopilot or cruise control engaged
Symptoms owners cite: Emergency brake applied suddenly; Emergency braking notification appears on screen; No obstacle or vehicle ahead; Driver was in full control of vehicle
Camera or sensor malfunction (phantom images, false detection)
Front and rear cameras display phantom images or fail to function correctly. Sensors detect objects that do not exist on road, triggering false braking events.
When: Various conditions; one owner notes issue after 12V battery replacement
Symptoms owners cite: Phantom images on front and rear camera display; Cameras fail to work as intended; Phantom objects appear on traffic display screen at edge of vision; Phantom objects appear before braking events on clear roads
Repairs/costs cited: One owner notes 12V battery was replaced 3 months prior to unintended acceleration event

What owners are reporting 4 most recent
While operating TACC with lane keeping assist, I experienced multiple iterations of phantom braking when the road and weather was clear ahead. This phantom braking could potentially cause other drivers to collide with the vehicle that unexpectedly braked in the middle of the highway. This problem has been a common issue with multiple people taking their cars to the service center to get checked…
Driving in freeway fast lane in light traffic at 10:30 am on overcast morning with Tesla adaptive cruise control set for 70 MPH and 4-car following distance. The car in front moved 1 lane to the right leaving no cars ahead. My car accelerated gently to 70 and then as I approached an overpass the car suddenly braked (or went to regeneration) and slowed instantly to about 40 MPH when I was able to…
Phantom braking: While in cruise or autopilot mode, it suddenly brakes on freeway without any obstacles observed.
