Owners describe brake failures across multiple systems. The most critical: loss of hydraulic pressure or vacuum causes hard, unresponsive pedals and complete brake failure at highway speeds (70 mph). One owner experienced brake failure after a camshaft recall repair that was software-only; the dealership later diagnosed camshaft failure and replaced it with the same part. Another had pedal pressure vanish when pressing the start button mid-gear, then return after engine restart—a scenario an independent mechanic traced to vacuum gauge line failure.
Brake pedal sticking occurs at low speed, locking solid and preventing depression—one owner crashed because of it. Separate complaints document grinding and cracking noises with extended stopping distances occurring repeatedly. ABS module communication is lost on at least one vehicle, disabling ABS and the speedometer.
The emergency hand brake's plastic engagement button breaks internally or pops off entirely, making the brake inoperable. NHTSA campaigns 15V705000 and 15V70000 address service brakes, but owners report manufacturers could not supply recall parts for months. VW's response to a camshaft-related brake failure was a software update only, which the owner correctly identified as illogical given the physical camshaft damage.
Failure modes owners describe
Loss of brake pressure / hard pedal
Brake system loses hydraulic pressure or vacuum, resulting in hard pedal and inability to stop the vehicle. One owner reports this occurred after a camshaft failure recall repair (software update only). Another experienced brake failure on a downslope when the start button was pressed mid-gear engagement, then pressure returned after the engine restarted.
When: 31,000 miles reported in one case; early mileage in others (14,907 miles, 5 miles)
Symptoms owners cite: Brake pedal becomes hard and unresponsive; Vehicle fails to stop when brake pedal is depressed; Brakes make abnormal crunching noise; Pedal travels to floorboard; Vehicle rolls forward uncontrolled; Extended stopping distance
Codes mentioned: Vacuum gauge line failure
Repairs/costs cited: One owner had vacuum gauge line replaced at independent mechanic; Fairfax VW unable to determine cause. Dealership replaced brakes at very low mileage (55 miles). One case involved replacement with 'same part' after camshaft failure diagnosis.
Recalls/TSBs owners mention: NHTSA Campaign 15V705000 (Engine and Engine Cooling, Service Brakes, Hydraulic) issued; parts unavailable for months. NHTSA Campaign 15V70000 (Service Brakes, Hydraulic) referenced. Camshaft recall 23R1 attempted as software-only update. VW case number 180105636 opened; manufacturer stated no fix available for camshaft-related brake loss.
Brake pedal sticking or stuck
Brake pedal locks in place or becomes immobilized, preventing the driver from applying brakes. One incident occurred at low speed and resulted in a crash.
When: Low mileage reported in at least one case
Symptoms owners cite: Brake pedal stuck in place and will not depress; Pedal will not respond to foot pressure
Brake noise and extended stopping
Brakes produce cracking or grinding noises when depressed and do not stop the vehicle immediately, requiring longer stopping distances. This occurred on multiple occasions for at least one owner.
When: 39,000 miles reported in one case; multiple occurrences
Symptoms owners cite: Cracking and grinding noise when brake pedal depressed; Extended braking distance; Vehicle does not stop immediately
ABS module communication loss
ABS module fails to communicate with vehicle systems, disabling the ABS system. Speedometer also becomes inoperative when this occurs.
Symptoms owners cite: ABS warning light illuminated; No communication with ABS module; Speedometer not functioning; EPC light on
Emergency brake button failure
Small plastic button that engages the emergency hand brake pops off or breaks internally, rendering the emergency brake inoperative. Owners report the internal plastic breaks and cannot be reattached.
Symptoms owners cite: Plastic button pops off emergency brake; Internal plastic breaks inside button; Emergency brake cannot be engaged without button
