NHTSA complaint #11665701, filed 2025-06“PCV system failed causing excess pressure to blow out the rear main seal and crankcase seal resulting in an oil leak.

Caused by poor design of shift position switches! This is a KNOWN issue for many GM vehicles including my 2019 Buick Sportback, for nearly 20 years. GM should be made to fix this.
