Well who would have known the my 2017 (bought last May) would have a shift to park issue? The DEALERSHIP! That’s who! I’m so mad they sold me that car knowing full well of its issue. Before buying the car, When I researched Acadias I didn’t see anything about it. Well supposedly, when I took it a month ago to have the issue fix at the dealership, the guy told me GM has a new shifter, etc to fix this! Great I thought, until 2 weeks after I get the car back and it’s doing it again. So they are going to have to fix it again. I could do this all day, but my warranty runs out next month. Then I’ll have to pay to have it fixed every month! GM SUCKS! Has anyone had it repaired and it fix the problem indefinitely?
3 times not fixed = lemon in Georgia. The warranty is on the new part, not the faulty one. Just holler if you me.😉

CARFAX. I bought my Acadia new so that wouldn't have worked for me. I found out the hard way too.

point of information. Once a vehicle has a repair done that repair is covered by a warranty for the next 12 mos or 12,000 miles.

The thing is. . If you read the TSB . . . in order to do the latest fix with the micro switch/wire harness . . . the whole shifter has to come out.
Maybe the dealer is electing to just replace the shifter rather than take the shifter out, unfasten and pull out the original micro switch and wiring harness (plus the Park interlock solenoid) which is part of it.
IMO .. . the new TSB repair is more time consuming than just replacing the whole shifter. GM should perhaps have dealers send the shifter core back to have the new parts retro fitted at a facility.

Disconnecting, unclipping the 2 connectors from the shifter, carefully undoing the wire harness and fishing the new wires back into the proper place requires some dexterity.
If a tech with bratwurst size fingers has to do it . . . . good luck.

Here is the part(s) that needs to be removed for the latest TSB. . . harness with switch and solenoid.

Without a doubt more time consuming.

Prior versions of the TSB paid .6 hours of labor for the repair on an Acadia. The latest version pays 1.4 hours.

IMO, unless the shifter has been modified, swapping shifters does nothing but kick the can down the road for another 20k miles.

Agree. . . unless the replacement shifter has that "new" micro switch and harness installed?

Frankly, unless the switch has been improved, or the over travel compression applying too much force onto the switch has been corrected, I expect to see this issue continue. But it does not appear so to me.

we had the issue but they replaced the shifter and no more issues. They now just do the sensors and harness.
My sister is having this issue with her 2017 Acadia. We are trying to figure out if it is covered by the power train warranty. Vehicle is less than 5 years old and has less than 60,000 miles but the dealership is saying it is not a covered repair. Should we believe him?

Yes, sad to say, probably not covered. You could, however, call GM Customer Service and reference the TSB for this issue or perhaps go to another dealer with this TSB in hand and ask if GM would help cover it.

I believe there were a couple of revisions to that TSB in 2021, none the less, it is not something covered by the power train warranty.

Unless you have a friend or family that is a service advisor, I doubt it is something that will be covered just because one walks into the service center with a TSB in hand.

TSB's are a tool for the tech, not for customers to negotiate free repairs.

It's doubtful a friend or family member would risk their job on a non-warranty repair that's performed under the guise of a covered repair. That's the best way I know to get the shop back-flagged during a warranty audit.

Doesn't like it seems it matters since the "Laura" has not been back to check or respond.

I had mine fixed last year and they charged me. I want to say it was like $300 as I was already out of the warranty period. I was sick of seeing that message and just sucked it up and had it fixed.

I have a 2018 Acadia SLT. It has had an ongoing issue with not recognizing when the vehicle is in PARK-I get a notification saying "Shift to Park" with the slightly annoying "ding! ding! ding!" that will not go off. I fidget with the gear, sometimes that works, while other times I start it, change the gears and slowly put it back in PARK...sometimes that works, while other times it does not. I have had it into the shop (GMC Certified) twice-which both times coded the switch, which is again being replaced, as I type! Anyone know of this happening commonly or did I just get a dud? If so, what was done. Nowadays, as you all know-if it doesn't code "there's nothing wrong"...frustrated with this plug and play world! I miss the days of REAL mechanics! But then, everything is electronic...ugh

Mine just started with this issue. My daughter's 2018 did this and after several trips to dealers she traded it for a 2019 which was supposed to not have the problem. Her 2019 is now doing it and my 2019 at 51K just started doing it. Just found this video and I say it is worth a try.
