Intermittent Shift to Park Message Displayed While Vehicle in Park. See #19-NA-206 (through DTC B000A may not be set!). 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.

GM needs to supply a fix.
