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.

What stands out
Owners have filed 31 brakes 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.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Phantom braking dominates the complaints. Owners on cruise control or autopilot report the car suddenly hard-braking at freeway speeds with no vehicles or obstacles ahead—sometimes dropping from 70 mph to near-stop in seconds. The system appears to misinterpret road shadows, overpasses, and grade changes as obstacles. Tesla has acknowledged this as a known problem but told owners there is no immediate fix and recommends not using cruise control.
Brake pedal failures are equally serious. Some owners pressed the brake and the car accelerated instead, or the pedal went unresponsive entirely, forcing them to steer off the road or allowing the vehicle to crash through a fence. One owner's car coasted backward after a collision impact despite regen braking being enabled.
Brake line corrosion and rupture caused total brake failure in two complaints. Owners reported fluid leakage and low brake fluid warnings; one found extensive corrosion in the wheel well and associated decay on the battery and subframes. Initial warranty denials are common, though some owners eventually got goodwill coverage.
Loose or detached brake caliper bolts appeared in multiple reports, with rattling and grinding at low speeds. NHTSA Campaign 21V387000 exists for this issue, but at least one affected VIN was not included.
Cold-weather brake freeze, brake response lag, and failures of the automatic emergency braking system round out the failures. Service centers often cannot replicate complaints and charge diagnostic fees without documenting root cause.

Failure modes owners describe
Sudden unintended braking on cruise control / autopilot (phantom braking)
Vehicle applies brakes abruptly while on cruise control or autopilot with no vehicles or obstacles present. Owners report the system interprets road shadows, grade changes, overpasses, and unclear imagery as obstacles. Events occur at freeway speeds (60-70 mph), sometimes so hard the vehicle nearly stops or causes swerving. Tesla has acknowledged this as a known problem but stated no immediate fix is available.
When: Freeway speeds typically 60-70 mph; reported from 2019 onward; occurs multiple times per trip or several times per week depending on driver
Symptoms owners cite: Sudden hard braking on cruise control with no vehicles ahead; Vehicle slows down 30-50% unexpectedly; Adaptive cruise control disengages without warning; Swerving nearly out of control from the hard braking; Phantom braking near overpasses, under shadows, on grade changes; Three beeps heard immediately before hard braking in one instance
Repairs/costs cited: Tesla support acknowledged the issue as a known problem but recommended not using cruise control. No service fix has been provided; problem persists across multiple model years and software updates.
Recalls/TSBs owners mention: Tesla admits it is a known problem but has no immediate fix. Recommends not using cruise control in their vehicles.
Brake pedal unresponsive or ineffective stopping
Brake pedal does not stop the vehicle or stops only partially. One owner reported the vehicle accelerated instead of stopping when brake was pressed. Another experienced the vehicle continuing to coast after impact despite regen braking being enabled. A third had all four wheels lock up during emergency braking.
When: Various speeds from parking lot maneuvers to highway speeds; one incident at 12 mph in parking, one during impact after collision
Symptoms owners cite: Stepping on brake pedal does not stop vehicle; Vehicle accelerates instead of stopping; Brakes fail to respond after impact; Vehicle coasts backward after braking attempt; All four wheels lock up; Regen braking does not engage as expected
Repairs/costs cited: One owner had generator braking able to stop vehicle. Another's vehicle had to be maneuvered to roadside to avoid collision. One incident resulted in vehicle crossing parking curb and ending in ditch.
Recalls/TSBs owners mention: Tesla service center stated 'nothing was wrong' after diagnostic despite brake failure alert appearing. Another owner's vehicle was not inspected despite third incident. Manufacturer did not document findings in some cases.
Brake line rupture / corrosion failure
Brake lines ruptured or corroded, causing loss of braking capability. One owner reported corrosion in driver's side front wheel well; another reported all four brake lines ruptured at 58,000 miles. Fluid leakage detected. Low brake fluid warning triggered.
When: One incident at 58,000 miles; corrosion occurred in driver's side front wheel well
Symptoms owners cite: Brake line rupture; Corrosion in wheel well area; Low brake fluid warning; Spraying sound while braking; Fluid leaking from brakes when parked; Vehicle failed to stop as needed; Associated corrosion on battery, subframes, and fasteners
Repairs/costs cited: Front and rear brake lines replaced. One repair facility estimate for related battery/subframe corrosion damage was $23,000, which would mechanically total the vehicle. Initial denial of warranty coverage by two service centers; second center eventually covered under goodwill.
Recalls/TSBs owners mention: Two Tesla service centers initially denied warranty coverage. After escalation to a Tesla shop in New England region, coverage was approved under goodwill. Corrosion damage to battery and subframes not covered under warranty.
Brake caliper bolt detachment / loosening
Brake caliper bolts detached or loosened, causing rattling and grinding noise. Owners reported bolts missing from front brake calipers and rear bolts appearing loose. Some bolts were torqued to spec by service center to prevent further issues.
When: One incident at 38,000 miles; another during low-speed maneuver (12 mph)
Symptoms owners cite: Rattling and grinding noise from front passenger tire area; Front brake caliper bolts detached; Rear brake caliper bolts loosened; Damage to tire and rim; No warning lights illuminated
Repairs/costs cited: Brake caliper bolts replaced. Service center torqued front caliper bolts to 94 NM and rear to 83 NM. One owner noted customer mentioned possible recall related to loose brake caliper bolts, but service center found no documentation. VIN was not included in NHTSA Campaign 21V387000 in one case.
Recalls/TSBs owners mention: NHTSA Campaign 21V387000 (Service Brakes, Hydraulic) exists for brake caliper bolts, but at least one affected VIN was not included in recall. Manufacturer did not open a case in one instance.
Vehicle acceleration or failure to apply brakes in parking / low-speed situations
Vehicle accelerates unexpectedly during parking maneuvers or when brake applied. Emergency braking does not engage. One owner applying brakes during parking saw vehicle accelerate instead; another backing out of driveway had vehicle 'take off' with no skid marks indicating brake use.
When: Low-speed parking maneuvers, one incident backing out of driveway
Symptoms owners cite: Vehicle accelerates instead of braking during parking; Emergency braking fails to engage; Vehicle continues forward despite multiple brake applications; No skid marks or evidence of braking; Vehicle crosses curb and enters ditch
Repairs/costs cited: One vehicle crossed parking curb, went into ditch; front damaged. Insurance paid expenses. Another vehicle drove through neighbor's fence and gate, came to stop in field with zero evidence of brake application (per law enforcement report).
Recalls/TSBs owners mention: Tesla informed of incident and stated they reviewed logs but found 'no issue.' No corrective action documented.
Automatic emergency braking system failure or delayed activation
Automatic emergency braking does not activate quickly or does not activate at all when warranted. In one incident, system beeped when car got close to another vehicle but did not brake in time. In another, emergency braking did not engage when vehicle was struck by another car.
When: One incident during highway near-collision; one incident during impact from collision
Symptoms owners cite: Emergency braking does not activate or activates too slowly; System beeps but does not brake quickly; No emergency braking engagement after impact
Repairs/costs cited: No repairs documented for this specific failure mode.
Recalls/TSBs owners mention: No manufacturer response documented for emergency braking failures.
Brake system frozen or difficult to disengage in cold weather
At 26°F, parking brake system seized. Vehicle required excessive accelerator pedal pressure (more than one-quarter deflection) to break free, creating danger in close-proximity parking.
When: Cold day at 26°F
Symptoms owners cite: Parking brake system seized; Vehicle difficult to move from parked position; Requires excessive accelerator pressure to disengage brake
Repairs/costs cited: No repairs documented.
Brake response lag or intermittent braking issues
Brakes respond slowly or inconsistently. Vehicle also exhibits issues with regenerative braking not engaging. In one case, vehicle continues to coast or maintain speed after driver releases accelerator when battery is not full, and manual brake application does not fully stop the vehicle.
When: Reported over last 10 days in one case; ongoing in another
Symptoms owners cite: Brake response lag at traffic lights; Vehicle hesitates before braking; Regen braking does not engage when expected; Vehicle coasts instead of decelerating; Manual brake application ineffective
Repairs/costs cited: No repairs documented.
