NHTSA Complaint #11616457 — 2020 CHEVROLET BLAZER

2020 Chevy Blazer - Shift to Park while Gear is already in Park: While putting the gear in park, the warning chime to shift it into park is initiated. It has happened 3 to 4 times in the past three days. I took the vehicle to the Local Chevy Dealership. The Service Team/Dept. diagnosed that the Transmission Shifter Unit Assembly must be replaced. The 2019 Chevy Blazer had these issues which prompted a TSB/Recall however it wasn't extended to the 2020-year models and Chevy Dealership refused to include it as a warranted repair which just passed 44,000 miles. This is a safety issue, and it should be replaced without additional cost to customer as this issue was already identified as a safety concern in 2019, however Chevy does not want to identify the issue as a covered repair per the manufactures warranty.
