Of the 15 brakes complaints filed for the 2024 Acura ZDX, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
A release of brake pressure can cause a loss of braking ability, increasing the risk of a crash.
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.
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.

2024 ZDX owners describe seven distinct brake system failures. The most severe is complete brake failure: the pedal sinks to the floor with minimal or no stopping power, sometimes triggered by driving over bumps or road objects. One owner at 390 miles experienced full brake loss with warning messages "Complete Outer Brake Failure" and "Stabili-trak Failure"; another at 11,000 miles drove through a red light before stopping.
Delayed brake engagement is reported as consistent and repeatable: the vehicle lurches and slips forward multiple times before braking force applies, worsening on wet pavement. This is not intermittent and occurs during normal braking.
The Automatic Emergency Braking system engages suddenly and without cause during reverse and forward driving—no obstacles, pedestrians, or cross traffic present. One owner reported six unexpected activations in a parking lot. Similarly, the parking brake engages unintentionally when reversing, immobilizing the vehicle.
Service Brake Assistance failures produce clicking or ticking sounds and jerking during stops; BRAKE Hold and Adaptive Cruise Control become unavailable. ABS activates unexpectedly during low-speed stops, releasing brake pressure. Hard braking causes wheel lock-up and forward sliding; low-speed stops produce forward lunges.
Across all failures, dealers cannot replicate the issues or find diagnostic codes. Acura reprogrammed software on at least one vehicle without resolving the problem and claims testing shows no defect. No recalls or software updates address these concerns.
Brake pedal depresses fully to floorboard with little or no braking response; vehicle fails to decelerate. Occurs at low speeds (under 40 mph) and can be triggered by driving over bumps or objects. Extended stopping distance and vehicle may drift through traffic lights.
When: At mileage 11, 15, 390 miles; some reports after low-speed impacts or road irregularities
Symptoms owners cite: Brake pedal sinks to floorboard; Minimal or no braking response; Extended stopping distance; Vehicle drifts forward despite pedal input; ABS and traction control warning lights may illuminate
Codes mentioned: Service Brake Assistance warning message
Repairs/costs cited: Dealers unable to replicate failure; no repairs completed. One case assigned emergency technician with no resolution. Arbitration initiated on at least one vehicle.
Recalls/TSBs owners mention: Cases opened, emergency technician assigned, NHTSA Campaign 24V614000 referenced but VINs excluded from recall coverage
Brakes do not respond immediately when pedal is depressed. Vehicle slips forward and lurches multiple times before braking force fully applies. Traction control activates only after significant forward motion. Condition is consistent and repeatable on both dry and wet pavement.
When: During routine and normal braking; not intermittent
Symptoms owners cite: Delayed brake response; Vehicle slips and lurches forward multiple times; Traction control system activates after delay; Loss of braking confidence; Worse on wet surfaces
AEB/Collision Mitigation Brake System engages unexpectedly and without external trigger—no obstacles, pedestrians, or cross traffic present. Occurs regularly during reversing and also reported during forward driving. Activation is sudden and jarring. Multiple owners report same issue on forums.
When: Mileage approximately 100 miles and throughout ownership; occurs repeatedly
Symptoms owners cite: Sudden, unexpected braking during reverse; Hard emergency braking without cause; Activation while driving forward with no threat present; No front or rear cross traffic or pedestrians present; Jarring, violent engagement
Repairs/costs cited: Dealership found no codes; advised disabling both front and rear systems
Recalls/TSBs owners mention: No software updates available to address; dealership recommended disabling AEB systems
Parking brake engages repeatedly and unintentionally when vehicle is in reverse, with no obstructions present. Disables the vehicle and forces manual release. One owner reported six activations preventing safe backing; another reported 2–3 activations during driveway backup.
When: Triggered specifically when shifting to or operating in reverse gear
Symptoms owners cite: Parking brake engages without driver input; Vehicle immobilized until manual release; No obstructions or safety triggers present; Repeated activation in single backing event
Repairs/costs cited: No repairs completed; dealership scanned but found no codes, attributed to safety features
Service Brake Assistance system fails to engage or function properly. Occurs when using manual regenerative brake lever or depressing brake pedal. Accompanied by clicking or ticking noise from brake pedal area and jerking sensation during deceleration. BRAKE Hold and Adaptive Cruise Control become inoperative.
When: Mileage 320, 4,100 miles; condition persists after service
Symptoms owners cite: Service Brake Assistance warning illuminated; Manual regenerative braking non-functional; Ticking or clicking sound when depressing brake pedal; Jerking sensation when coming to stop; BRAKE Hold feature unavailable; Adaptive Cruise Control inoperative
Codes mentioned: Service Brake Assistance warning
Repairs/costs cited: Dealership reprogrammed undisclosed software; failure persisted after repair. Another vehicle returned after service with problem continuing; dealership found no stored codes despite symptoms.
Recalls/TSBs owners mention: Manufacturer notified of failure; case opened
ABS activates unexpectedly during routine low-speed stops (approximately 10 mph) without cause. Releases brake pressure in the service brake system, causing unexpected complete stop or loss of controllable deceleration.
When: At mileage approximately 10,080 miles during normal low-speed approach to stop
Symptoms owners cite: Unexpected ABS activation; Brake pressure released without cause; Sudden complete stop; No warning lights reported
Repairs/costs cited: Vehicle not diagnosed or repaired
Recalls/TSBs owners mention: Associated with NHTSA Campaign 24V614000 (Service Brakes, Hydraulic) but VIN excluded from recall coverage
During hard braking, wheels lock and vehicle slides forward with reduced or lost deceleration. Also reported lunging forward during slow-speed stops (5–10 mph) with full pedal engagement. Wheel lock-up creates dangerous sliding behavior.
When: During hard braking maneuvers and low-speed stops (5–10 mph)
Symptoms owners cite: Wheels lock up during braking; Vehicle slides forward despite brake pedal engagement; Reduced deceleration or complete failure to stop; Forward lunge at low speeds; Dangerous sliding behavior
Recalls/TSBs owners mention: Manufacturer test-drove customer vehicle and new comparison unit; claimed both exhibit same behavior and stated nothing is wrong with the vehicle

The contact owns a 2024 Acura ZDX. The contact stated that while driving 35-40 MPH and depressing the brake pedal, the brake pedal went down to the floorboard, and the vehicle slightly responded, causing the braking distance to be extended and the vehicle drove through the red traffic light before stopping. There was no warning light illuminated. The contact was able to continue driving. The…
Multiple times, while both reversing and driving forward, the vehicle has initiated hard emergency braking maneuvers when no emergency exists -- no rear or front cross traffic, no pedestrians. This is dangerous and could initiate a crash with other cars following the vehicle.
The braking system does not engage properly and is worse in the rain. When adaptive cruise control is on, the car does not slow down at every instance when there is a car in front slowing down. When the car finally realizes there's an object/car in front it then slips before engaging in traction control, which seems to make the car actually slide forward rather than attempting to stop immediately.
When hard braking the car doesn’t stop, you can feel the wheels lock up and it slides forward. Some times when stopping at slow speeds the car will lunge forward. I almost hit a car, went in an intersection and one time almost hit a person and I was only going 5-10 mph that time and I hit the brakes and the car slid forward. I am really scared and Acura says they test drove mine and a new one and…
When backing up the car will slam on its brakes when there is NOTHING behind me. Most of the time it is when I am backing out of my driveway it will do it 2-3 times when nothing is there. It has done it a couple of times backing out of a parking space when nothing is there. I reported this to Acura but they didn’t do anything about it.
This is the most recent time that the automatic brake on my car kicked in for no reason. It has happened several times and I have made Acura aware of it, but this is the first time it has almost caused an accident because the car behind me almost rear-ended me. A Similar incident happened last year and I brought it in and they did nothing since they could not replicate it. I let the dealership…
The automatic rear braking system on my 2024 Acura ZDX engages unexpectedly and without cause. It happens regularly when reversing, even though there are no obstacles, people, or vehicles behind the car. The sudden braking is jarring and creates a real safety concern, especially in traffic or tight spaces. I took the vehicle to my local Acura dealership, but they had no information or guidance…
