If you enjoy optimizing your Chevy Corvette‘s performance and honing your white-knuckle driving skills, the Performance Data Recorder (PDR) can be a significant help to getting what you want out of your Bow Tie sports car. However, GM has identified an inoperative PDR issue in the 2024 and 2025 Corvette for which it has a partial solution.
According to The General’s official bulletin on the subject, bulletin number PIC6571, the issue is a “software anomaly” that may cause the PDR in your 2024 or 2025 Corvette to fail to work properly. When activated, the Performance Data Recorder application either displays a blank screen or that will fail to open at all. In some cases, a welcome screen is displayed, but the PDR remains inoperable.
Initial testing to see if the anomaly is causing the PDR malfunction consists of pressing the radio display’s Home button while the inoperable PDR application is active. If the software glitch is the cause, the display will exit the application and the radio home screen will appear as normal.
Currently, the GM fix for the 2024 and 2025 Corvette problem consists of resetting the 12-volt battery of the Chevy C8 Corvette. The global reset needs to be carried out “for a full five minutes” per the bulletin’s instructions to service personnel. The fix is conducted by detaching the battery cables and holding them in contact for the duration of the reset to discharge any remaining power in the Vette.
This procedure usually restores correct function to the Performance Data Recorder. GM remarks that “the issue is very unlikely to return at that point in time,” but does leave open the possibility that the procedure won’t fully remedy the issue in some cases. In this case, Service Information (SI) diagnostics should be used to determine if there are additional problems causing the PDR malfunction.
Notably, GM appears to be continuing the attempted development of a solution that won’t require resetting the battery of the 2025 Corvette units affected by this issue. The 2025 Chevy Corvette continues to ride on the GM Y2 platform. Production takes place at the GM Bowling Green plant in Kentucky.
