Shift to park warning on other Acadia 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, 2020, 2021.

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

Recalls and investigations

One recall on the transmission and drivetrain covers the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.

Is this a known problem?

The manufacturer has sent NHTSA 2 service bulletins or notices for the 2019 GMC Acadia 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

“Our Arcadia 2019 with 40000 miles has shift to park problem. 2017 thru some 2019 had recall notice and were fixed by GMC. Why doesn't it apply to this vehicle. We had to pay $1500 to dealer. There is an obvious problem and they have admitted it. Time for government to step in or do a class action lawsuit looks like they are filed by state”

“My vehicle just hit 39K miles, it has all of a sudden started giving me a Shift Into Park warning. The sensor is not registering that its in park and will not let you turn car off. There is a recall on the 2017-2018 vehicles for this issue and but many report an issue with the 2019, when I called GMC they would not fix. How to we go about having this included in the recalls?”

Should you keep driving it?

This page can't tell you that. 0 of 144 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.
