2020 Chevrolet Traverse Shift to Park Message When Parked

Owners report a persistent “shift to park” warning even when the vehicle is already in park, which can interfere with shutoff and normal operation.

The problem

Owners report a persistent “shift to park” warning even when the vehicle is already in park, which can interfere with shutoff and normal operation. CarComplaints currently lists this exact vehicle-and-defect pairing in its “Current Problem Trends” page, which compiles issues reported within the last 90 days.

Cause and mechanics

Possible causes include shifter assembly defects, switch misalignment, wiring faults, or electronic transmission control issues.

On defect pages like this, the best practice is to explain both the symptom owners see and the mechanical or software pathways that could produce it. That makes the page useful to consumers while also creating a framework for later supplementation with TSBs, recall records, expert analysis, and repair-order evidence.

Prevalence

The issue is significant because it affects normal vehicle operation and appears often enough to be listed as a current trend.

Because the CarComplaints trend page is directional rather than exhaustive, prevalence should be described carefully: the listing shows a recent concentration of complaints, but it should be paired with NHTSA complaint counts, recall data, dealer repair volume, and any litigation allegations before making stronger prevalence claims.

Legal claims

Depending on the owner's repair history, warranty terms, mileage, and state of purchase, several claims may be available:

• Breach of express warranty for repeated unsuccessful replacement or adjustment of shift components.
• Magnuson-Moss claim if GM cannot permanently repair the defect.
• Lemon law claim if the condition substantially impairs use or value and persists after multiple repairs.
• State consumer protection claims may be considered if GM knew the shifter system was defect-prone.

For breach-of-warranty and Magnuson-Moss claims, the strongest facts usually include multiple documented repair attempts, continuing symptoms after software updates or part replacement, and evidence that the defect affects safety, reliability, or resale value. Lemon-law viability turns on state-specific thresholds, including reasonable repair attempts, days out of service, and whether the defect substantially impairs use, value, or safety.

Source notes

Also check for related NHTSA complaints, technical service bulletins, recalls, and any manufacturer field actions that may bear on causation, notice, and remedy. Those materials can help establish prevalence, prior knowledge, and the inadequacy of repair efforts.
