GM recalls 33,000 Corvettes due to software issue affecting turn signals

General Motors is recalling 32,988 Chevrolet Corvette vehicles from the 2025 and 2026 model years. The recall stems from a software glitch that prevents the system from detecting a failure in the rear turn signal, which violates FMVSS No. 108 safety standards.

What Happened

According to NHTSA, the defect is linked to software in the exterior lighting control module. If a rear turn signal fails, the driver might not receive a dashboard warning, increasing the risk of a traffic accident. This issue arose after a software update from the taillight supplier in October 2024. That update, intended to simplify the tire pressure monitoring system (TPMS) calibration procedure, inadvertently disrupted the turn signal diagnostic function.

Technical Details

The recall affects various Corvette versions, including coupes and convertibles, as well as hybrid models like the E-Ray and ZR1X. Production of the impacted vehicles spanned from October 2024 to February 2026. To fix the problem, GM will update the lighting control module software. This update will be available at dealerships and via over-the-air (OTA) methods for compatible cars.

Market Impact

Despite no reported accidents or complaints, the company has launched a large-scale service campaign covering nearly 33,000 vehicles. Owner notifications will begin on May 18, 2026.
