On certain Model 3 vehicles, brake lines may be corroded beyond acceptable limits, which may result in loss of brake fluid. Loss of brake fluid will result in a customer facing alert if the fluid reaches the predetermined level to trigger an alert. Upon customer complaint of a low brake fluid alert, evidence of a brake fluid leak, or a failed periodic roadworthiness inspection, inspect the brake lines. If corrosion is found on any of the brake lines, replace all brake lines on the vehicle with new corrosion-resistant parts, in one combined repair. NOTE: Due to dual reduncancy, vehicle safety is not impacted by corrosion on the brake lines.

The failure pattern owners describe
Owners of 2023 Tesla Model 3 vehicles report serious, unpredictable braking failures across three categories. First, phantom braking occurs during cruise control, TACC, Autopilot, or Autosteer operation—the vehicle suddenly applies full brakes on clear roads with no traffic or obstacles in sight. Owners describe hard, sudden braking that can activate seatbelt restraints, slow vehicles from highway speeds to 35–40 mph, or occur 15–20 times in a single driving session. These episodes feel random and cannot be reliably reproduced, making diagnosis difficult.
Second, owners report complete brake failure: firm brake pedal presses that fail to slow the vehicle adequately, resulting in rear-end and frontal collisions. Accompanying this, automatic emergency braking and collision warning systems have failed to activate or alert drivers despite imminent threats.
Third, owners report regenerative braking malfunctions—either unexpected full engagement at highway speeds or sporadic failure on downhill roads—plus unintended acceleration while braking, particularly in parking scenarios, and intermittent failures of Auto Hold and Creep mode functions.
Tesla service centers have offered no solutions, claimed lack of available technicians, and dismissed issues as non-serious despite video evidence and collision damage.

Failure modes owners describe
Phantom Braking / Unintended Emergency Braking
Vehicle applies full brakes suddenly and forcefully with no obstacle, hazard, or traffic ahead. Occurs during cruise control, Traffic-Aware Cruise Control (TACC), Autopilot, or Autosteer. Owners report episodes of hard braking that have slowed vehicles from 70 mph to 35–40 mph or caused seatbelt restraint activation. Multiple incidents per trip are common. One owner reported approximately 15–20 unintended brake applications in a single 2-hour highway drive.
When: Highway and freeway operation; most commonly at sustained speeds (60–70 mph) with automated driving features engaged. Speculation includes: low visibility conditions (shade, dawn/dusk), asphalt color changes, bridge approaches, accumulated bugs on forward camera, and oncoming semi-trucks in adjacent lanes.
Symptoms owners cite: Sudden, firm brake application without warning; Vehicle slowing or near-stopping with clear road ahead; Seatbelt restraint activation from hard braking; Behavior appears random and often irreproducible; Occurs with Cruise Control, TACC, Autopilot, or Autosteer enabled; Loss of vehicle control sensation; difficulty maintaining lane or speed
Codes mentioned: Automatic Emergency Braking Unavailable, Traction Control malfunction, ABS malfunction, Lane Departure alert, Stability Control disabled, Brake Hold Unavailable
Repairs/costs cited: Tesla service has not offered a remedy; one service center suggested extended test drives to reproduce the fault. Multiple owners report Tesla support unable or unwilling to diagnose. No repairs documented.
Loss of Braking Function / Brake Pedal Unresponsiveness
Vehicle fails to decelerate despite forceful brake pedal application. Reported in two collision scenarios: (1) hard brake application during regenerative braking transition did not slow vehicle prior to rear-end collision; (2) hard brake application during emergency maneuver (SUV cutting in front) failed to stop vehicle in time, resulting in collision with lead vehicle. In both cases, the driver felt confident they were pressing the brake pedal firmly and repeatedly.
When: ~11,000 miles (Narrative #1); low-speed collision scenario (Narrative #4). Timing relative to regenerative braking or automated feature activation unclear in #4.
Symptoms owners cite: Brake pedal pressed hard and repeatedly; vehicle continues at speed or decelerates too slowly; Collision occurred due to insufficient braking response; In one case, Tesla incident report confirmed brake pedal was pressed but acceleration was not reduced until collision
Repairs/costs cited: Both incidents resulted in vehicle collisions. Damage sustained; in one case damage was considerable and the owner reported lack of confidence driving afterward.
Automatic Emergency Braking System Failure
Automatic Emergency Braking (AEB) and Collision Avoidance systems failed to activate or warn when warranted. Owners report no collision warning, automatic braking, or safety feature activation despite configured to be enabled and despite imminent collision scenarios (e.g., approaching vehicle decelerating, vehicle cutting in).
When: ~11,000 miles; low-speed scenarios
Symptoms owners cite: No collision warning alerts displayed; No automatic braking engagement; Safety systems did not activate despite being enabled in settings; System failed when manual braking also failed
Codes mentioned: Automatic Emergency Braking Unavailable
Repairs/costs cited: Not repaired; owner reports significant loss of confidence in vehicle safety systems.
Regenerative Braking Malfunction
Regenerative braking (regen) either engages unexpectedly or fails to engage when expected, particularly on downhill or steep mountain roads. One owner reports intermittent and unpredictable function; another reports unexpected full regen engagement during highway driving with no driver input.
When: Mountain/steep road operation; highway driving during cruise control use. Noted during warm days with battery charge between 70–80%.
Symptoms owners cite: Regen braking engages suddenly and unexpectedly during normal highway travel; Regen braking fails to engage or works sporadically on downhill/mountain roads; Unpredictable behavior; sometimes works, sometimes does not; Unexpected regen braking described as startling and potentially dangerous at freeway speeds
Repairs/costs cited: Tesla support unable to help; no technicians available or knowledgeable. Owners sent video evidence and timestamps but received no response or solution.
Unintended Acceleration During Braking
Vehicle accelerates unexpectedly while driver is attempting to brake or reduce speed, particularly at low speeds in parking scenarios (creep mode) and on one occasion while actively pressing the brake pedal on a roadway.
When: Low-speed parking maneuvers; roadway driving during low-speed deceleration attempts
Symptoms owners cite: Vehicle accelerates instead of decelerating when brake pedal is pressed; Occurs during Creep mode operation in parking garage; Vehicle propelled into parked vehicle or building; Accompanied by intermittent unavailability of Deceleration Mode selection on touchscreen
Repairs/costs cited: Touchscreen reboot briefly restored Deceleration Mode option, but issue recurred. No permanent repair documented.
Auto Hold / Creep Mode Malfunction
Auto Hold feature (or Creep mode in parking scenarios) intermittently fails to hold vehicle, or vehicle accelerates unexpectedly when held in place. One reported incident of unintended acceleration into another vehicle while parked in Creep mode.
When: Parking and low-speed maneuvers
Symptoms owners cite: Auto Hold feature does not reliably engage or maintain hold; Vehicle rolls or accelerates when it should be stationary; Unintended acceleration into parked vehicle while in Creep mode
Repairs/costs cited: Tesla service advises feature is not 'serious' and requests customer reproduce error; no resolution offered.
Deceleration Mode Unavailability
Touchscreen control for Deceleration Mode becomes unavailable, preventing driver from adjusting regen braking strength or switching between braking modes.
When: During low-speed driving attempts; September 2025
Symptoms owners cite: Deceleration Mode options missing from vehicle settings display; Options reappear briefly after touchscreen reboot but become unavailable again; Coincides with unexpected acceleration events during braking
Repairs/costs cited: Touchscreen reboot temporarily restores options but fault recurs.
