Cadillac XT5 Sunroof Dead After Mechanic Service

Had a similar sunroof control issue with my 2019 Cadillac XT4 last year. The sunroof reset procedure became necessary after electrical work was done. The vehicle sunroof system often needs recalibration when the battery is disconnected or after certain repairs. The initialization error you describe typically indicates the sunroof control module lost its programming. A proper diagnostic revealed the module needed recoding, not replacement. The automobile sunroof system requires specific initialization steps: 1. Press and hold the sunroof switch in the fully closed position 2. Release after complete closure 3. Press forward again within 5 seconds 4. Hold until the sunroof completes a full cycle If this reset procedure fails, the issue likely requires professional diagnostic equipment to recode the control module. This is a moderately serious issue that should be addressed promptly to prevent potential water leaks or further electrical complications. The convertible top malfunction is likely connected to the same control module. Both systems share electrical architecture in the XT5. A qualified dealer should be able to perform the necessary coding and reset procedures to restore full functionality.

Thanks for sharing your experience. My XT5 had nearly identical symptoms last summer after some electrical work. The sunroof reset attempts didnt work for me either, and I ended up needing professional reprogramming of the control module. Can you recall the repair cost for your situation? Mine came to around 380€ for diagnostics and reprogramming, but prices can vary. Did you experience any other electrical glitches after getting the sunroof operation fixed? Just wondering if I should watch out for related issues.

The sunroof initialization error on my XT4 was successfully resolved by the service center. The vehicle sunroof system only required a control module recoding which cost 75€. The repair was straightforward and took about an hour to complete. No additional electrical problems surfaced after the sunroof reset and recoding. The sunroof control has worked flawlessly since then, with both the sunblind and main panel operating normally. Your 380€ repair cost seems quite high compared to my experience with just the coding work. The automobile sunroof system in these models is generally reliable once properly initialized. Having a qualified technician perform the right coding sequence is crucial for preventing recurring issues. Since the fix, all sunroof functions including tilt, slide, and express modes have performed exactly as designed.

The problem with my sunroof mechanism was finally resolved last week. After getting fed up with the failed reset attempts, I took it to a certified Cadillac dealership. The sunroof troubleshooting revealed the previous mechanic had disconnected the battery without properly following reinitialiation protocols. The service cost was 380€ which covered full diagnostics and control module reprogramming. Although pricier than expected, the sunroof calibration was done correctly this time. Both the sunroof and convertible top are now working perfectly. The sunroof control responds smoothly to all commands and the error message is gone. Looking back, I should have gone straight to the dealer for this specialized electrical work. At least the problem is fixed and I know where to go if any similar issues come up in the future. Thanks again for the helpful advice about the control module recoding.
