NHTSA Complaint #11661974 — 2019 CHEVROLET COLORADO

My 2019 Chevrolet Colorado, equipped with the 3.6L LGZ engine, recently triggered a P0024 diagnostic trouble code. This code indicates a failure of the Bank 2 exhaust camshaft position actuator solenoid, a critical part of the variable valve timing (VVT) system. After researching, I discovered that General Motors has issued Special Coverage N232430470 for this exact issue on the 2020 Chevrolet Colorado, which uses the same LGZ engine and solenoid system. Despite the identical failure and engine design, my vehicle is not currently included in the coverage. I believe this reflects a systemic defect that affects multiple model years — not just 2020 — and that GM is choosing to limit coverage unfairly. This failure can result in check engine warnings, drivability issues, reduced fuel economy, and possibly emissions system non-compliance. I am requesting NHTSA to investigate whether this VVT solenoid issue warrants a broader recall or special coverage extension across model years with the LGZ engine (including 2019).
