Was kinda wondering is there shift to park recall? Had brought my 19 Denali to the dealer for transmission shift problem and was told there’s shift to park recall. Thought it’s only on the acadias but now terrains? It’s also sad that even on the GM recall website and the app says there’s none. Or is it a TSB? At the same time the dealer loaned me a Encore GX as wel.

It might be a very small group if any. I have 2019 Terrain and i have not heard of any recall. I also have not had any issues.

How does the 3 cylinder feel in the Encore GX

The shift to park "message" issue actually started out on the Malibu and Camaro (?) before even the Acadia a few years ago.
The same basic shifter "cartridge" design is used on several GM vehicles. . .. possibly most as models are refreshed apparently.

The initial fix was for a service tech to "flick" the shifter switch button 50 times : :eek:hno:

Along with installing an " In-line Shifter Wire Harness Jumper"

The real problem in my estimation, is the park switch contact itself is not robust enough to handle the current rush and is getting oxidized. Then poor contact is made and the park position signal is not being sent to the vehicle electronics.

IMHO .. . a proper fix would be to find and install a switch with the proper current handling capacity and the 'In-line Jumper" which apparently is just a current limiting resistor network. See the attached PDF below . . .

Correction5386336Verify the condition and following the steps in the Service Procedure below, install an In-line Shifter Wire Harness Jumper between the shifter base connector and the console harness connector.

Service Procedure :

1. Park the vehicle in a repair stall and turn the ignition off. 5386339
2. Remove the transmission control lever knob
(3).Refer toTransmission Control Lever Knob Replacement in SI.
Important: - Cleaning the Park Switch electrical contacts is a very critical part of the repair procedure. - - Ensure these steps are not overlooked.
3. Clean the Park Switch electrical contacts by doing the following steps: 5386341
3.1. Depress the actuation rod fully with your thumb or a trim stick.
3.2. Release the actuation rod by sliding your thumb or the trim stick off the rod, allowing the rod tosnapback to the full up position.
3.3. Repeat 50 times.

I just thought it was a surprise that it didn’t show up on the GM recall website. However, it was on the dealership system for some reason. I took my vehicle in for the transmission issue that it would hesitate/slip after cold start from 3rd to 4th gear. (

As far as for the Encore GX. The one I was being loaned to is a Encore GX Select with ST package. Since it’s a FWD, it has the 1.2T 3 cylinder with CVT. It’s definitely peppy for sure. Once you hit the guess it goes. However it’s a CVT so so who knows who’s the manufacturer for the GM CVT. Hoping it’s not bad like Nissan CVT.

Interior Wise, it’s smaller than the Terrain for sure. Definitely bigger than the regular Encore. Being a Buick, I would expect the soft touch material fall through the rear like the Envision and Enclave. But in this case, it’s only soft touch in the middle portion. The upper portion for the rear doors are hard plastic like the Terrain. The vehicle as equipped is about 32k with nitrogen tires. It does equipped with power tailgate, ST package, it was a nice touch of the Buick logo projected to the ground of where the tailgate is so you can stick your foot out to open it. It also includes Nav. Automatic emergency braking and other safety nannies are standard like the 2020 Terrain is. I believe the LED headlight is only standard on the Essence. I’m also not sure if you can get rear air vents for the back passenger as this loaner didn’t have it.

Overall it’s pretty nice for sure as a two passenger vehicle/crossover. Avg size adults could probably fit in the back. If you’re over 6 ft and you have a driver that’s 6 ft as well would be a snug. If I was looking at this, I would probably look at the 1.3 AWD with the conventional 9 speed for a little bit more power. 1.2 has about the same power as the old 1.4. 1.3 has about 155hp I believe. Any other questions, let me know.

Agree about the CVT. . . GM has been working on use of a CVT since the early 2000s and actually used some in several small car models like in the Spark and some non US markets IIRC. However, the SPark uses a Jatco CVT smaller than the VT40 CVT like in the +2019 Mailbu.

Also used in the new 1.5L Malibu as shown below.

From what I can tell, GM co-developed the VT40 CVT.
Here is an article that talks about the GM CVT that you had when you drove the Encore GX: -

And and interesting video on how a CVT works.

Have you heard anything about the transmission issue regarding the slip for 3-4 when cold. Have the same issue at times.

The dealer is waiting on the technician to come back to work within these couple of days so we’ll see what happens.

Dealer padding. First discount on the negotiations.
CVT not for me unless it's free...

I just had an oil change done at the dealership and was informed on the Shift to Park Recall. The service manager didn't say much but said there will be an update to the ECM with it being an electronic transmission. Didn't really say what the issue is but will be going in on Monday to have the work done.

This is the field action description that is on my appointment.

I guess they haven't sent out the letters or updated the websites yet.

Transmissions have been electronic for many years now. GM and Chrysler co developed one back in the 90s or maybe even earlier.
That said. .. these newer ones are made with the trend to be even more sophisticated and fussy. What with Torque Converter Clutches now instead of the earlier and simpler Lock Up Torque Converter there is more programming and complexity that doesn't seem to translate into predictable operation it seems for all car brands. All in the interest of meeting EPA mandates and getting energy "credits" for tricks in how the transmission and engine work together.
