Acura ZDX GM-Ultium Problems, Recalls & Lemon Law

brake pedal problem; reduced braking; unexpected braking; brake warning light

NHTSA recall 24V614000 confirms the 2024 ZDX ABS may release brake pressure unexpectedly at speeds below 25 mph, directly impairing stopping ability. An OTA software fix was the offered remedy; owners who experienced the defect before the August 2024 remedy date, or whose OTA update failed and required a dealer visit, can count those visits toward California's four-repair presumption under Song-Beverly. If the vehicle exhibited reduced braking on more than one occasion despite dealer contact, the safety-defect path to a buyback or replacement is well-supported by the recall record alone.

The electronic brake control module software will be updated through an over-the-air (OTA) update or by a dealer, free of charge. Owner notification letters were mailed September 26, 2024. Owners may contact Acura customer service at 1-800-382-2238. Acura's number for this recall is UJE.

front suspension noise; stabilizer bar loose; vehicle pulls or clunks

NHTSA recall 25V018 (118 units) documents that improperly torqued front stabilizer bar bracket bolts can loosen and damage the ZDX's high-voltage cables or EV battery coolant lines, potentially shutting the vehicle down without warning. For owners whose vehicles required HV cable or coolant-line replacement — not merely bolt retorquing — the component failure is a substantial impairment of use and safety under Song-Beverly. The small production run affected (118 vehicles, March–October 2024) means owners should verify their VIN is covered and confirm the dealer's repair order specifies what was found and replaced.

Dealers will inspect and tighten the bolts, and repair the stabilizer bar and bracket, high voltage cables, and EV battery coolant lines as necessary, free of charge. Owner notification letters were mailed February 24, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numb

front suspension noise; stabilizer bar loose; vehicle pulls or clunks

NHTSA recall 25V234 covers a second production batch of nine 2024 ZDX vehicles with the same stabilizer bar bracket bolt defect as recall 25V018. Although the unit count is very small, the underlying defect — risk of HV cable damage and sudden vehicle shutdown — is the same safety hazard. If an affected owner's vehicle required more than one dealer visit to properly address the bolt condition, or if HV cable damage was discovered, that repair history supports a Song-Beverly claim on safety grounds.

Dealers will inspect and tighten the bolts, and repair the stabilizer bar and bracket, high voltage cables, and EV battery coolant lines as necessary, free of charge. Owner notification letters were mailed May 30, 2025. Owners may contact Honda customer service at 1-888-234-2138. Honda's number for

backup camera blank; screen goes black in reverse; rearview camera distorted

NHTSA recall 26V112000 confirms six independent software defects in the ZDX's Radio Control Module can cause the instrument cluster to go completely blank while driving — hiding the speedometer, warning lights, and indicators — and can simultaneously blank the rearview camera. Honda's own filing concedes non-compliance with FMVSS 101, 111, and 305. Because the recall fix requires a dealer appointment (not an OTA push), every pre-remedy visit where an owner complained of a blank cluster or camera counts toward the Song-Beverly four-repair presumption. Owners whose vehicles experienced the defect across multiple dealer visits before the recall parts became available in April 2026 have a particularly strong recall-backed lemon-law case.

Dealers will update the vehicle radio control module software, free of charge. Owner letters were mailed April 22, 2026. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are TNL and XNK. Vehicle Identification Numbers (VINs) involved in this recall will

backup camera blank; screen goes black in reverse; rearview camera distorted

NHTSA recall 26V306 (15,688 ZDX units; some sources report 14,688) confirms that inadequate plasma-irradiation pre-treatment of the camera housing adhesive surface causes the rearview camera image to become blurry, distorted, or completely absent. Dealer notification was not scheduled until May 2026, meaning owners who reported a failed backup camera during the months prior had no available recall remedy. Each pre-remedy dealer visit for this condition — plus any post-remedy recurrence before camera hardware was replaced — supports a Song-Beverly repair-attempt count. The recall is a hardware fix (camera unit replacement), not a software patch, which distinguishes it from recall 26V112 and means the condition cannot recur through software regression.

Dealers will replace the rearview camera, free of charge. Interim letters, notifying owners of the safety risk, are expected to be mailed July 6, 2026. Additional letters will be sent once the remedy is available, anticipated in late 2026. Owners may contact Honda's customer service at 1-888-234-213

Infotainment screen goes black after OTA update; GPS, Apple CarPlay, and Android Auto stop working; hands-free Bluetooth disabled; climate and audio controls unresponsive; dealer scan required to restore; system requires replacement module in severe cases

A bricked infotainment system that disables safety communications, GPS, and driver-assistance alerts qualifies as a substantial impairment of use under Song-Beverly (Cal. Civ. Code §1793.2). If a dealer requires multiple visits to restore the system — or installs a replacement module that experiences the same failure — the repair history supports a repeat-repair / no-permanent-fix argument. Owners should obtain written repair orders for each dealer visit even if the dealer characterizes the issue as a 'software update.'

Dealer applies Techline Connect rollback to restore baseline firmware, then re-flashes sequentially. Vehicles on SQBR5-250 can update directly. In brick cases requiring hardware: Radio Control Module replacement (covered under warranty).

Driver display goes black while vehicle is in motion; speedometer, warning lights, and turn-signal indicators disappear; center touchscreen also blank simultaneously; condition may clear after restart but recurs; rearview camera also blank when in reverse

Loss of the instrument cluster while driving — including loss of speedometer, warning lights, and turn-signal indicators — constitutes a safety defect under FMVSS 101 and 111, creating strong recall-backed grounds for a Song-Beverly claim. Because recall 26V112 requires a dealer visit (not an OTA fix), owners experiencing this defect before notification are entitled to count each pre-remedy visit toward the repeat-repair threshold. If the condition persisted through multiple dealer attempts before the recall remedy was available, the vehicle may meet California's four-repair or 30-day presumption.

Dealer updates Radio Control Module software (not OTA — requires dealer appointment). Updated software already incorporated into 2025 MY production.

Vehicle slams on the brakes unexpectedly with nothing in front or behind; reverse AEB engages repeatedly during driveway maneuvers; parking brake automatically applies while backing up; sudden violent stop from highway or city speeds; CMBS warning light triggers without collision; system cannot be disabled via settings; occupants experience jolting, neck pain, or near-rear-end collisions by following traffic

Phantom AEB activation at highway speeds, or reverse AEB that repeatedly immobilizes the vehicle, constitutes a safety defect that substantially impairs use and value. Because dealers frequently cannot duplicate ADAS events — AEB activations leave no persistent fault codes — owners must document each incident with dashcam footage, timestamped photos of the odometer, and written dealer repair orders noting 'cannot duplicate.' Under Song-Beverly, the manufacturer's inability to replicate does not excuse the defect; repeated visits for the same complaint still count toward the four-repair presumption.

No dedicated recall or TSB issued as of Jun 29, 2026 specifically for ZDX CMBS phantom braking. Dealers have updated ADAS software and, in some cases, replaced forward radar sensors. Owners report inconsistent resolution; many dealer visits log 'cannot duplicate.'

'High Voltage System Warning' message on cluster; sudden loss of drive power; vehicle enters reduced-power or limp-home mode; inverter overheat warning; vehicle becomes undriveable; requires flatbed tow to dealer

Sudden loss of propulsion while driving represents a safety defect that could trigger a crash, supporting a Song-Beverly claim on safety grounds regardless of mileage. Owners should document the High Voltage System Warning message (photograph the cluster), note the date, mileage, and conditions, and request the dealer record the HV fault code in the repair order. If propulsion is lost more than once, the repeat-repair pattern is established even if individual visits are classified as 'not duplicated.'

Dealer diagnosis of inverter cooling circuit; replacement of drive motor control module or cooling pump as indicated. Covered under Acura's 8-year/100,000-mile EV battery and drive-system warranty.

Regen paddle on steering wheel fails to engage maximum deceleration; 'Service Brake Assistance' warning illuminates on cluster; BRAKE Hold feature stops functioning; vehicle does not slow as expected when lifting off throttle; jerking or lurching sensation when decelerating; clicking sound during brake application; one-pedal stop mode deactivates without driver input

Regenerative braking inconsistency that triggers 'Service Brake Assistance' warnings and disables the BRAKE Hold function impairs the vehicle's primary braking capability, meeting the safety-defect threshold for Song-Beverly purposes. If the condition recurs after the EBCM software update (recall 24V614) was applied, that failed remedy strengthens the argument that the manufacturer was unable to conform the vehicle to its implied warranty within a reasonable number of attempts.

EBCM software update (same OTA remedy as recall 24V614); in some cases additional diagnostic of brake-by-wire actuator required. Dealers should log specific fault codes from the EBCM and regen controller.
