Questions to ask

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

What software versions were installed before and after service?
Were stored, pending, or historical infotainment, connectivity, or camera faults found?
Is the remedy OTA, dealer-side procedure, calibration, or hardware replacement?
Were driver-assist and camera systems tested after service?
If the issue followed an OTA update, were update logs reviewed?
Will the service record identify the final remedy and affected modules?

Documents to request

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

Repair order with technician notes
Diagnostic summary listing infotainment, connectivity, and camera-related codes
Written confirmation of software versions before and after service
Written confirmation of whether OTA or dealer-side update was performed
Documentation of any camera or driver-assist verification performed
Closed service record showing warranty classification

Pre-service evidence

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

Photograph or video-record infotainment faults when safe
Screenshot myChevrolet app errors and OTA notifications
Document whether the issue began after an OTA update or service visit
Note whether cameras, maps, audio, or driver-assist systems were affected
Record odometer reading at service drop-off and pickup
Retain communications regarding future software remedies

Service advisor interaction

Operational notes specific to the conversation at the service desk.

Ask Chevrolet to document whether the issue was software-only, calibration-related, or hardware-related.
A generic 'software updated' note is incomplete without software-version detail.
If the issue cannot be reproduced, request written confirmation that historical logs were reviewed.
Camera and driver-assist complaints should be documented separately from infotainment concerns.
If a future OTA is expected to resolve the issue, request written confirmation.

Repair authorization

Cautions before signing.

Do not authorize paid software or infotainment diagnostic work until warranty classification is clarified in writing
If hardware replacement is proposed, request written warranty determination before approval
Separate unrelated work from infotainment or software concerns before approval
Review authorization forms carefully before approving additional work

Post-service verification

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

Verify displays remain stable during a short drive
Verify app connectivity and status reporting function normally
Test camera and driver-assist features if they were affected
Confirm software version matches service documentation
Confirm the service record identifies the final remedy
Save the closed service record

Warranty notes

Software-only remedies do not extend warranty unless Chevrolet states otherwise in writing.
Goodwill repairs do not extend warranty coverage. Confirm classification in writing.
Repeated infotainment complaints should be documented as recurring service history.

Observational patterns

Infotainment complaints should document software version, OTA timing, and affected features.

If the issue follows an OTA update, request written confirmation of which modules were updated.

Camera and driver-assist display issues should be documented separately from infotainment inconvenience.
