On the 2020-2025 Cadillac CT5, cT5 owners report the center infotainment display freezing, becoming unresponsive to touch, or hanging during an over-the-air or dealer-pushed software update — a common symptom is a black screen with a blue progress bar stuck at 99%. The condition is documented on a 2020 CT5 case where a Cadillac-issued Technical Service Bulletin was required to be applied at the dealer to recover the module. Secondary symptoms include incorrect clock display on the instrument cluster after the screen recovers, indicating a system-wide software fault rather than a touchscreen hardware failure. Note: 2020-2024 CT5 uses the pre-Google GM infotainment platform; the CT5 only received Google built-in starting with the 2025 model year, and the reboot procedure differs between the two generations.
Try a soft reset first. On 2020-2024 CT5 (pre-Google infotainment): press and hold the infotainment power button (left of the touchscreen) for ~10 seconds until the Cadillac logo reappears. On 2025+ CT5 (Google built-in): with the vehicle in Park, press and hold the steering-wheel phone hang-up button for 10-15 seconds; ignore the on-screen options and the system will reboot in ~5 seconds. If the unit remains stuck (especially at 99% during an update), the fix must be performed at a Cadillac dealer per the active Cadillac TSB, which reflashes the infotainment module. Avoid interrupting any software update by shutting the car off mid-flash — that is the most common trigger for the stuck-update state. A weak 12V battery can also corrupt updates, so have battery state-of-health checked before any reflash.

On the 2020-2025 Cadillac CT5, the CT5 uses GM's 10-speed automatic (10L80) that can exhibit harsh shifts, delayed engagement, and shift hunting, particularly when the adaptive learning resets. The 10-speed has very complex shift logic and can take 500+ miles to fully adapt to a driver's pattern after a battery disconnect, TCM update, or reset. Some CT5 owners report persistent shift quality issues even after adaptation. The CT5-V and CT5-V Blackwing have refined calibrations but can still exhibit occasional harsh shifts.
Have dealer perform latest TCM software calibration - GM releases regular updates. Allow 500+ miles after any reset for the transmission to relearn. For persistent issues, a full transmission fluid exchange with Mobil 1 LV ATF HP can improve shift quality. Very few CT5s require hardware repair.
