2019 Buick Regal Powertrain & Transmission Problems

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. In addition to not being able to start car and running down battery because of car power still being on and endangering the personal safety of every person using GM vehicles, it is possible Steering Lock may or may not occur and many vehicle accessories may not operate correctly. GM needs to supply a fix.

The contact owns a 2019 Buick Regal. The contact stated after parking the vehicle, the “Shift to Park” message was displayed. The contact shifted the gear shifter back and forth to park until the message disappeared. The vehicle was taken to the dealer where it was diagnosed with a failed gear shifter unit and console. The contact was informed that the gear shifter unit and console needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 39,500.

PCV system failed causing excess pressure to blow out the rear main seal and crankcase seal resulting in an oil leak. No lights and no codes were on the dashboard. The only symptom was a high pitched squealing sound during very cold weather. The problem has been reproduced by the dealer. The problem first appeared the first winter owning the vehicle.

We are concerned about how safe our vehicle is when in "park". We will, on occasion, get a "Place in Park" message when the shifter is clearly in the park position. The dealership is not aware of any service bulletins or recalls, and since the problem is intermittent cannot offer a clear assessment.
