The failure pattern owners describe
Brake vibration dominates complaints. Owners describe steering wheel pulsation and shuddering at 40–50 mph, sometimes severe enough to jolt the wheel from their hands during panic braking. Multiple owners had the same issue "fixed" four or five times before it recurred. Ford issued TSB 22-2023 acknowledging brake pad material sticks to rotors in cars built through early 2022, but the company has not recalled the defective pads and denies warranty coverage on the grounds that vibration is wear-and-tear.
Parking brake and rear disc brake failures add a second major category. Owners report brakes locking up after wet driving in cold conditions, requiring multiple restart attempts to release. One owner experienced complete loss of regenerative braking on a mountain pass, triggering "Stop Safely Now" warnings and leaving the vehicle immobilized.
Less frequent but serious: all four rotors warped after only 200 miles of light driving; one owner's brakes failed entirely, resulting in a collision and injuries; one-pedal drive mode disabled unexpectedly post-recall, once daily in one case; and power brake assist failed completely with multiple warning lamps.
Dealers have performed brake service under warranty in some instances but refused coverage in others, citing normal wear despite obvious defects documented in Ford's own service bulletins.
Failure modes owners describe
Brake vibration and pulsation from stuck or worn pad material
Brake pad material adheres to rotors, causing steering wheel vibration at highway and moderate speeds (40-50 mph). Owners report the issue recurring after multiple dealer 'fixes,' with intervals between occurrences shortening. Ford TSB 22-2023 documents that pad material becomes dislodged and attaches to rotors. In one case, the steering wheel vibrated violently enough to jump out of owner's hands during a panic stop.
When: 16,500–30,000+ miles; some issues appear within weeks of purchase or recall service
Symptoms owners cite: Steering wheel vibration when braking; Pulsation feedback through brake pedal; Vibration most pronounced at 40–50 mph; Loud thumping or metal-on-metal grinding noise during braking; Violent vibration from specific wheels (rear in some cases)
Repairs/costs cited: Dealers replace brake pads and rotors; one owner quoted $1,300 for repair. Repeated replacements required; one owner had pads and rotors replaced 4 times in 42,000 miles. Owners report warranty denial citing 'wear and tear' despite TSB documentation.
Recalls/TSBs owners mention: Ford TSB 22-2023: Vibration/Pulsation From Brakes - Brake Pad Material Stuck To Rotor - Built On Or Before 06-Jan-2022. Ford redesigned brake pads but has not issued a recall. Some warranty repairs performed; others denied.
Stuck parking brake or rear disc brake
Parking brake or rear disc brake locks in the engaged position, immobilizing the vehicle or causing it to require multiple attempts to release. After parking in cold, wet conditions, brakes become stuck. Loud thumping and violent vibration from rear wheel occurs when brake finally releases. Service parking brake alert displays on dash.
When: Cold, wet weather; after wet driving followed by garage parking
Symptoms owners cite: Parking brake remains engaged; vehicle will not move; Loud thumping sound from rear wheel; Violent vibration from rear wheel; Service parking brake system alert on dash; Multiple restart attempts required to release brake
Repairs/costs cited: Vehicle towed to dealer; repair details not provided in narratives
Loss of regenerative braking and one-pedal drive mode malfunction
One-pedal drive mode disables unexpectedly, removing regenerative braking assistance and forcing reliance on friction brakes. In one case, complete loss of regenerative braking on a mountain pass caused sudden speed increase, warning messages ('Stop Safely Now,' '1-Pedal Drive Fault'), loss of drive power, and vehicle immobilization. Another owner reports one-pedal drive disabling once daily after recall work. A third reports recurring 'one pedal driving fault' after battery connector recall.
When: Post-recall; one incident at unspecified mileage; another at 46,140 miles (different failure mode—brake failure altogether); one case following HVBJB recall
Symptoms owners cite: One-pedal drive mode disables without warning or with dash warning; Loss of regenerative braking on downhill grade; Unexpected vehicle acceleration when off accelerator; Warning messages: 'Stop Safely Now' and '1-Pedal Drive Fault Press Brake Pedal To Reduce Speed'; Loss of drive power; vehicle coasts to stop; Vehicle fails to restart or shift out of Park
Repairs/costs cited: One owner did not take vehicle to dealer. No repair costs provided.
Recalls/TSBs owners mention: No manufacturer response documented in narratives; issue appears related to prior recalls.
Complete brake failure during operation
Brake pedal depression resulted in no vehicle deceleration, leading to a collision with another vehicle. Owner sustained neck, head, and arm injuries requiring medical attention. Police report filed. Failure occurred at approximately 46,140 miles.
When: 46,140 miles
Symptoms owners cite: Brake pedal depressed but vehicle did not slow down; Vehicle crashed into another vehicle
Repairs/costs cited: Vehicle towed to body shop; manufacturer was not notified of failure
Rapid rotor warping without excessive use
All four brake rotors warped simultaneously after only 200 miles of driving since the last 10,000-mile service inspection, which included brake check. No excessive braking, heat, or water exposure reported. Rust ring visible around rear rotors in a similar complaint.
When: 200 miles after service inspection; under 11,000 total miles in another case
Symptoms owners cite: All 4 rotors warped at once; Harsh metal-on-metal noise during low-speed braking; Visible rust ring around rear rotors; Noticeably longer braking distances in low-speed applications
Repairs/costs cited: No specific repair details provided; one dealer stated the condition was 'normal' despite grinding noise and weakened braking performance
Power assist braking and brake booster failure
Lack of power assist in braking and power steering, with anti-lock braking, electronic stability control, traction control, hill start assist, and pre-collision assist all disabled. Multiple warning lamps and text messages displayed at startup. Dealer recommended replacement of the brake booster. Owner states VIN is not associated with any unrepaired recalls despite matching a known recall for same make, model, and year.
When: Not specified
Symptoms owners cite: Loss of power-assisted braking; Loss of power steering; Anti-lock braking disabled; Electronic Stability Control disabled; Traction Control System disabled; Hill Start Assist disabled; Pre-Collision Assist disabled; Multiple warning lamps illuminated; Text messages displayed on instrument cluster
Repairs/costs cited: Dealer recommended brake booster replacement; repair cost not stated
Recalls/TSBs owners mention: Recall exists for same make, model, and year but VIN not associated with unrepaired recall
Parking brake electronic control failure post-recall
Parking brake becomes stuck in the engaged position or fails to function after completion of battery connector recall work. Service parking brake system alert displayed. New wiring harness installation required to restore functionality, mirroring the original recall repair.
When: Post-recall work
Symptoms owners cite: Parking brake stuck in engaged position; Parking brake no longer functional; Service parking brake system alert on dash
Repairs/costs cited: New wiring harness installed to correct failure, identical to recall repair procedure
Recalls/TSBs owners mention: Parking brake issue appears to be a consequence of prior recall work

What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
