Acura ZDX · 2024–2025 · all trims

Reported symptoms

Infotainment screen freezes, reboots unexpectedly, or becomes unresponsive during driving
DC fast charging session refuses to initiate, terminates early, or sustains charge rate well below specification
Type S performance mode behavior inconsistent or fails to engage as expected

Charging session terminates with high-voltage system error or 'Service charging system' message

Questions to ask

Pose these to the service advisor at intake. Request answers in writing or via email.

How many open recall and software campaigns currently apply to VIN (Vehicle Identification Number) [VIN], including any cross-platform Ultium campaigns originally issued under GM brands?
What software versions are currently installed on the relevant modules, and which versions correspond to the closed remedies for each open campaign?
Has the Acura dealer cross-referenced GM Ultium-platform and Honda Prologue service campaigns when assessing VIN [VIN]?
If the vehicle is a Type S variant, are there any campaigns specific to the dual-motor configuration that should be addressed?
Is each remedy delivered via OTA (Over-the-Air software update), dealer-side flash, or hardware adjustment?
Will all open campaigns be addressed in a single visit, or are sequential visits required?

Documents to request

Each item should be received in writing before authorizing repair work.

Diagnostic report listing all stored, pending, and historical fault codes from the affected modules
Repair order with technician notes, including a list of every recall and campaign reference number addressed during the visit, with cross-platform Ultium and Honda Prologue references explicitly noted
Written confirmation of software versions installed before and after the visit on each affected module
Written confirmation of which campaigns are now closed for VIN [VIN] following the visit
Documentation of any Type S-specific service procedures applied, if applicable to the vehicle configuration

Pre-service evidence

Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.

Screenshot or video-record any infotainment, display, charging, or performance mode defects at the time they occur
Note specific incidents — system reboots, charging failures, Type S mode behavior, ambient conditions — with dates
Save all Acura correspondence regarding software updates, recalls, or feature delivery timelines
Screenshot the AcuraLink app status pages over time, showing any reported errors
Save records from third-party charging network apps showing failed session details
Note odometer reading at drop-off and at pickup

Service advisor interaction

Operational notes specific to the conversation at the service desk.

Record the full name of the service advisor and the technician performing the work
Acura dealer service operates at premium-tier customer service expectations. Service interactions should match the premium positioning, but verify written documentation matches verbal commitments — premium service experiences can include verbal characterizations that go beyond the documented record
Cross-platform Ultium campaigns originating under GM brands or related to the Honda Prologue may apply to the ZDX but require active cross-referencing by the Acura dealer service system
Type S variants have dual-motor configurations with distinct software calibrations. If the issue relates to performance behavior, request written confirmation that the diagnostic addressed the Type S-specific calibration rather than only the base system

Repair authorization

Cautions before signing.

Recall and software campaign work is performed at no charge to the owner; do not authorize any charge for parts or labor associated with these campaigns
If a diagnostic fee is presented, request written confirmation of whether the fee is refundable if the issue is later determined to be recall- or campaign-covered
Premium-tier service expectations include amenities (loaner vehicle, vehicle pickup, etc.); these are operational courtesies, not warranty entitlements, and any commitments should be documented in writing
Repair authorization signatures often include language permitting additional related work — read the document and decline blanket additional work in advance

Post-service verification

Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.

Verify the infotainment system functions normally without unexpected freezes or reboots during a short test drive
Conduct a verified DC fast charging session at a CCS-compatible fast charger before traveling more than a short distance from the dealership
If the vehicle is a Type S variant, test performance mode engagement and behavior across a representative driving scenario
Confirm no warning messages or system errors on the cluster, head-up display, or AcuraLink app after a full ignition cycle
Confirm the repair order matches the work performed and references the correct campaigns
Retain copies of all post-repair documentation in case of recurrence

Warranty notes

Acura has issued recalls and service campaigns affecting the ZDX during the early production period. The applicable campaigns for VIN [VIN] should be checked at every service visit, including any cross-platform Ultium and Honda Prologue campaigns.
ZDX components are covered under Acura's New Vehicle Limited Warranty and the high-voltage battery component warranty (8 years / 100,000 miles in most US markets). Coverage period and conditions should be confirmed in writing.
Recall remedies are performed at no charge to the owner regardless of vehicle age, mileage, or warranty status. A recall remains open until performed.
Repairs performed under goodwill rather than warranty or recall do not extend the warranty period. Confirm in writing which classification applies.

Observational patterns

The Acura ZDX is built on GM's Ultium platform under the same Honda/GM joint venture as the Honda Prologue. Recall and service campaign coverage for cross-platform defects depends on Acura dealers actively cross-referencing GM service bulletins and Honda Prologue campaigns.

Premium-tier dealer service experiences can include verbal commitments that exceed the written record. Material commitments — loaner duration, completion timing, scope of inspection — should be confirmed in writing.

Type S variants of the ZDX use a dual-motor configuration with distinct software calibrations. Diagnostic procedures appropriate for the base ZDX may not fully address Type S-specific behavior.

Acura is in the early period of EV-specific dealer service capability. Service quality and EV-specific diagnostic familiarity vary between dealer locations during this transition.
