The vehicle should not roll while in park... the message is a result of a faulty signal / input from the shifter that tells the computer that the vehicle isn't in park when in reality it is firmly in park. Not a safety issue, just a real annoyance.Here’s a possibility, perhaps a lawsuit based on rolling over people including the driver as they were trying to get out of the p.o.s. I have a 2018 Denali doing the same **** thing. Has 17k on it. Haven’t got it to the dealer yet but am working up patience for the battle.
Does anyone have a link to the TSB issued that has the fix for this issue?Also new here. Sorry if I missed others with this same issue ... my '17 Acadia Denali began the "Shift to Park" notice in the DIC when turning off vehicle a few weeks ago. Happened for about 3 days and then one (very cold) day when I went to start it parked in a parking garage, the vehicle would not shift - at all - out of park. Car started just fine, but also noticed that a few electrical components weren't working - heated seats, heated steering wheel, front blower and right tail lights. Long ordeal, but had it towed to dealer - they fixed the shift lock-up issue immediately, but took two weeks (working with GM engineers) to diagnose what was causing the electrical problems. Finally diagnosed as a loose wire connection that they believed was exacerbated by the cold (the electrical issues would resolve on their own when the vehicle was left in shop overnight; acted up again if left outside). Anyway, got the Acadia back in two weeks.
Had it for about a week and the "Shift to Park" issue returned. I will have to bring it back to the dealer to see about this, but thankfully none of the other issues have returned. Wondering if anyone else has had these other problems.
GM knew there was an issue. The pending PIP told us this a while back. But they have to go in redesign, test and then produce the parts. Unfortunately auto makers follow this parts and generally do not speak out on just what the issue is. Even dealers are generally left in the dark.Ok everyone here is what you have been looking for.
TSB 18-NA-297 Replace Transmission Shifter Control Assembly.
Shifter F 13528228
This is the TSB for the shift to park complaint. It addresses the dealer to change the entire shifter control with a new updated part.
This should solve the issue. Mine was in today and the number comes from the invoice. No hassles and no questions they took the Acadia in and had it fixed in 3 hours.
I was expecting issues after reading here but they had the new TSB and the part was in stock.
I hope this helps. No need for any more fighting with dealers, useless class action lawsuits and no frantic I have to trade this off anymore.
If you are having the issue video it or take a photo to show them what is going on if it is intermittent.
The new shifter appear to have less play.
I do not have the full TSB yet but I should be able to get it at work next week if it is published yet.
Anyways it is fixed and no grief thanks to Toth GMC.
Easy to get a ballpark figure for that yourself. Use the part number to find out what the shifter costs on a GM parts site. Use full list price because that's what the dealer will charge you. Then, estimate labor will be about 2-2.5 hours @ your dealership's labor rate. Labor rates vary more than part prices as a general rule.Has anyone on this thread had this repaired out of warranty? What was the cost? ...
Maybe the dealer had a brand new (but old inventory) shifter on the shelf and just did an exact swap. The new shifter assembly is a different part number.So.... I recently had this “shift to park” issue with my 2017 Denali at around 29,000 miles. Last weekend the dealer replaced the shifter assembly, which is the prescribed fix still, correct? Today my wife reported that she got a “shift to park” message but it was much easier to clear than before. I’m thinking I’ll wait a week or so and see how it goes before running back to the dealer. How many others have had problems after the shifter assembly was replaced?
