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?
What software versions are currently installed on the relevant modules, and which versions correspond to the closed remedies for each open campaign?
Is each remedy delivered via OTA (Over-the-Air software update), dealer-side flash, or hardware adjustment?
Has the Cadillac dealer confirmed Super Cruise functionality is current following the visit, including the most recent map data update?
Will all open campaigns be addressed in a single visit, or are sequential visits required?
What loaner vehicle arrangement applies during the service period, given the Escalade IQ's distinctive size and feature set?

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 including Super Cruise and Executive Second Row systems where applicable
Repair order with technician notes, including a list of every recall and campaign reference number addressed during the visit
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 Super Cruise map data update applied during the visit

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 Super Cruise defects at the time they occur
Note specific incidents — system reboots, charging failures, Super Cruise disengagement events, ambient conditions — with dates
Save all GM correspondence regarding software updates, recalls, or feature delivery timelines
Screenshot the myCadillac app status pages over time, showing any reported errors
If towing was required to bring the vehicle to the dealership, retain the tow receipt with the service file (large vehicle dimensions affect tow requirements)
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
Premium-tier Cadillac service expectations include amenities (loaner vehicle, vehicle pickup, etc.); these are operational courtesies, not warranty entitlements, and any commitments should be documented in writing
The Escalade IQ's distinctive features (Super Cruise hands-free, Executive Second Row, Theater Configuration) require specialized diagnostic procedures. Confirm in writing that the technician has worked with these subsystems recently.
Multi-campaign software situations are particularly susceptible to incomplete documentation. A general 'software updated' note without enumerated campaign references creates ambiguity about which specific campaigns are closed.

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
If high-voltage component replacement is quoted on a flagship vehicle, request written warranty classification before signing the repair authorization, given the substantial component costs
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
Test Super Cruise engagement and disengagement on a representative section of mapped roadway
If equipped, test Executive Second Row features for correct operation
Verify all camera systems (rearview, surround view) display correctly under normal conditions
Confirm the repair order matches the work performed and references the correct campaigns

Warranty notes

Cadillac has issued recalls and service campaigns affecting the Escalade IQ during the early production period, including cross-platform Ultium campaigns. The applicable campaigns for VIN [VIN] should be checked at every service visit.
Escalade IQ components are covered under Cadillac'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.
Super Cruise map data updates are part of ongoing service rather than warranty work; confirm the current map version is installed during any visit involving driver-assist diagnostics.
Recall remedies are performed at no charge to the owner regardless of vehicle age, mileage, or warranty status.

Observational patterns

The Cadillac Escalade IQ is GM's flagship Ultium-platform vehicle, sharing architecture with multiple lower-tier Ultium vehicles. Cross-platform campaign coverage is operationally relevant — campaigns issued under Chevrolet, GMC, Honda, or Acura branding may apply.

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

Super Cruise functionality depends on map data currency in addition to vehicle software. A 'software up to date' statement should be cross-checked against the specific Super Cruise map data version.

Large vehicle dimensions and high vehicle value create logistical considerations during service that smaller vehicles do not — towing capability of the disabled vehicle, garaging requirements, transport of loaner-equivalent replacements. These considerations are part of the operational picture but not warranty entitlements.
