Service Bulletin - Vehicle-Wide Programming (VWP), also known as SPS3-VWP, is a feature within Techline Connect (TLC) to update all applicable control module software at the same time. When initiated, all applicable updates are done in parallel, instead of the conventional individual control module update. Customers may have complaints or concerns that may get resolved by doing this software update.

What stands out
Owners have filed 29 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
The 2024 Prologue's brake and collision avoidance systems are generating alarm across the fleet. Owners report two major categories of failure: total loss of braking function and unwanted automatic braking activation.
Total brake failures appear early, often within the first two weeks. Vehicles display "Brake System Failure 43 MPH Max Speed," "Brake Assist Failure," and "Service Stabilitrak" warnings. The brake pedal either goes unresponsive or requires extreme physical force to engage, sometimes forcing the car to roll downhill uncontrolled. One vehicle failed twice in nine days despite dealership repair; another needed a brake master unit replacement, then failed again within days. Dealerships have struggled to diagnose—some report loose connectors, others a faulty brake booster, but fixes don't stick.
The Collision Mitigation Braking System activates violently with no vehicle, obstacle, or threat present. Owners report sudden hard stops at highway speeds (70 mph), during city turns, and in normal traffic, causing whiplash injuries and near-miss rear-end collisions. The reverse collision detection is worse: owners report 50% false activation rates while reversing, multiple stops within a single 60-second backup, and frequent triggering during rain with zero obstructions. The system engages the parking brake involuntarily, stranding vehicles mid-maneuver. Owners cannot disable or adjust sensitivity.
One vehicle accelerated uncontrollably at 2,000 miles with the steering wheel frozen and brakes failing—it was declared a total loss after a collision. A safety camera error caused another to stop dead in an intersection. Dealerships across multiple states report having no solution and customers unable to get appointments for weeks.
Failure modes owners describe
Unexpected automatic emergency braking activation (forward driving)
Collision Mitigation Braking System activates with forceful, sudden braking when no vehicle, obstacle, or collision threat exists. Occurs on straightaways, during turns, and in normal traffic conditions. Multiple owners report near-miss rear-end collisions from vehicles behind them, and in one case whiplash injuries to passengers.
When: Occurs unpredictably throughout vehicle operation; one incident at ~70 mph, others at 10-15 mph and during normal city driving within first weeks to months of ownership
Symptoms owners cite: Sudden, violent braking without warning or visible threat; No obstacle or vehicle detected ahead; Whiplash injuries to passengers from abrupt stops; Near-miss rear-end collisions from trailing vehicles
Repairs/costs cited: No factory fix offered; owners report disabling the safety feature entirely as only workaround. One dealership had no solution after 30+ days in shop across multiple appointments.
Reverse automatic emergency braking malfunction
Reverse collision detection system activates hard braking repeatedly when backing out with no vehicles, obstacles, or obstructions present. Occurs frequently in rain and dry conditions. System engages parking brake involuntarily, leaving vehicle stranded mid-maneuver. Owners unable to disable or adjust sensitivity through vehicle settings.
When: Occurs 50% of reverse operations on some vehicles; several times per week or even multiple times within 60 seconds. First incidents reported within days to weeks of delivery.
Symptoms owners cite: Hard, violent braking while reversing with no obstruction present; Parking brake engages involuntarily, immobilizing vehicle; Multiple false activations during single reverse maneuver; Frequent false activation in rainy conditions; Sudden jolts and violent stops endangering passengers
Repairs/costs cited: No repair or factory adjustment available. Owners report dealership unable to replicate issue or provide fix. Only option is disabling feature, negating its safety purpose.
Total brake failure with loss of braking function
Complete loss of braking capability with multiple warning lights (Brake System Failure, Brake Assist Failure, Service Stabilitrak). Vehicle will not respond to brake pedal input or responds only with extreme pressure applied. One-pedal driving becomes unavailable. Vehicle rolls uncontrollably or requires full body force on pedal to engage brakes slowly.
When: Occurs within first 10 days to two weeks of delivery; recurring incidents one week after initial repair. Multiple repeat failures on same vehicle.
Symptoms owners cite: Brake pedal unresponsive or goes nearly to floor with no stopping power; Multiple warning lights: 'Brake System Failure 43 MPH Max Speed', 'Brake Assist Failure', 'Service Stabilitrak'; One-pedal driving unavailable; Vehicle rolls uncontrollably despite brake pedal depression; Extreme pedal pressure required with slow brake engagement; Speed limited to 43 mph
Codes mentioned: Brake System Failure, Brake Assist Failure, Service Stabilitrak
Repairs/costs cited: Dealership initially diagnosed loose brake connector. Replaced with brake master unit on second failure. Brake booster ordered on third occurrence. New module ordered after fourth service attempt. Multiple repair cycles (2-4 weeks each) with recurring failures.
Recalls/TSBs owners mention: Dealership software update attempted but system could not connect, requiring additional software update. Multiple failed attempts to reprogram vehicle. One owner filed lemon law claim; another refused to drive vehicle and requested return of lease.
Brake system difficulty with warning messages
Brake pedal becomes extremely difficult to depress, requiring full body force and multiple pumping motions to gain sufficient pressure for stopping. Warning messages indicate system failure with 43 mph speed limit. Brakes function normally after vehicle shutdown and restart.
When: Occurs after restart; one incident at 18 miles from delivery. Issue reoccurs when vehicle delivered to dealership for diagnosis.
Symptoms owners cite: Brake pedal extremely difficult to engage, requiring full body force; Brake cylinder pressure insufficient, requiring pumping action; Brake system failure warning at 43 mph max speed; Brakes function normally after shutdown and restart; Temporary nature of failure makes diagnosis difficult
Codes mentioned: Brake system failure
Repairs/costs cited: Dealership unable to determine cause after four days of inspection. Cause and effect remain undiagnosed.
Loss of one-pedal driving without warning during AWD fault
AWD Temporarily Unavailable message appears without indicating that one-pedal driving is disabled. Driver expects one-pedal braking to engage but vehicle continues at speed, creating near-miss collision hazard at intersections.
When: Upon vehicle startup with AWD fault present
Symptoms owners cite: Vehicle does not slow when foot released from accelerator as expected with one-pedal driving; Vehicle continues at speed through stop sign; No indication in warning message that one-pedal driving is disabled; Near-miss collision at intersection
Codes mentioned: AWD Temporarily Unavailable
Unintended acceleration with brake pedal unresponsiveness
Vehicle accelerates independently while steering wheel becomes frozen. Brake pedal depressed but vehicle does not stop. Resulted in collision. Air bag deployed. Vehicle declared total loss. No warning lights were reported before failure.
When: Approximately 2,000 miles on vehicle
Symptoms owners cite: Steering wheel frozen; Vehicle independently accelerates at unknown speed; Brake pedal unresponsive despite depression; Vehicle unable to be controlled; No prior warning lights
Repairs/costs cited: Vehicle towed from scene to impound lot and declared total loss by insurance
Recalls/TSBs owners mention: Manufacturer was informed of failure
Front safety camera error causing unexpected stop
Error with front safety camera causes vehicle to stop abruptly in middle of intersection. Driver forced to coast vehicle into nearest parking lot. Error self-clears.
When: Single incident reported
Symptoms owners cite: Vehicle stops in middle of intersection; Safety camera error displayed; Error clears itself without intervention
Repairs/costs cited: Dealer unable to provide assistance or fix
