NHTSA Complaint #11612205 — 2021 CHEVROLET TRAILBLAZER

Odometer: 50,379 Purchased used on April, 1 2024 Odometer: 47,027 Brought to dealer on 8/28/2024 for service. About two weeks ago we had a "Shift to Park" message is displayed on the DIC after the vehicle was placed in Park and shut off. Started it again and then put it in drive then back to park. Message went away. Then over the course of the next week this happened many more times to the point where we were stuck in a shopping parking lot because we could not leave the car as it kept beeping to fix the issue. Made appointment with dealer. After Diagnose from dealer they said it needed to perform Service Bulletin #23-NA-119, recommend replacement of transmission control. They at first wanted us to pay for it and we advised dealer we had a Chevy warranty. After a few days they advised it would be covered under warranty except for our $50 deductible. Main problem is the part # 13545091 was not available locally and dealer had to research to find part. Advise it could take until 9/26/24 to find part. This should be a no charge RECALL by the Mfg. as this can be a safety issue and to ensure more parts are in stock by dealer.
