NHTSA Complaint #11646104 — 2022 CHEVROLET TAHOE

The check engine light illuminated cause us to park the vehicle until diagnosed. The diagnosis is the Onstar system has failed causing the check engine light to illuminate. Even without paying the fee for onstar the light still illuminates rendering the vehicle “disabled” under Indiana clean air requirements. They will not run the required emissions test to certify or plate your car with a check engine light on. The dealer stated the vehicle can still be driven however we will no longer know if there are ancillary issues because the check engine light goes on and off. Ironically this happened two months after a software recall performed by the dealer. If the vehicle is safe to drive with an onstar failure there should be no reason the check engine light illuminates taking attention away from more serious potential issues.
