Shift to park warning on other Traverse years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2017, 2020, 2024, 2025, 2026.

What this problem usually is

This sheet covers a dash message that says "Shift to Park" or "Service Shifter" when the car is already in Park, or when it's sitting in Drive with the shifter lights glowing. Owners say it won't let them turn the car off, or it flashes up on the highway.

What got replaced

Is this a known problem?

The manufacturer has sent NHTSA 3 service bulletins or notices for the 2018 Chevrolet Traverse that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“Just started happening: on occasion, when trying to shut vehicle off, the accessory light kicks on and DIC says "SHIFT TO PARK". I have to restart the car many times and shift it from drive to park to finally get it to shut off. The issue is commonly discussed on youtube. It's the sensor/switch that tells the car it's in park. Please offer a fix.”

“SHIFT TO PARK error comes up when park to shut down. Does not allow shutdown of the car without beeping notices. Not allowing doors to lock or driver to exit. Must be fairly common as Google shows a lot of workarounds or how to fix a clip under the shifter knob down in the console.”

“Car has many issues: Jerks Shift to park error when it is parked causing car to have lights on for hours Brake error Fuel issue Traction error Computer failure at times I got the car used was not fixed when I received it needs recalls I have kids you people expect me to pay for your faulty equipment please make this right if I het into an accident it's because of your brand”

Should you keep driving it?

This page can't tell you that. 0 of 94 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
