2017 GMC Acadia

Shifter shifts to park but park will not engage. The vehicle chimes a warning that the vehicle is not in park. This was replaced by a GMC dealership under warranty in 2019. The problem has now came back. One of the parts ladies has the same year vehicle and replaced her in 2019 and just had to replace her again last month. The vehicle is out of warranty now and the dealership has not looked at the vehicle yet because my daughter drives it but she’s in college 5 hours away. There is no warnings both times this has happened.

I believe my vehicle has a software issue, the temperature gauge will read cold, I will get a “Steering assist reduced drive with caution” message, my A/C stops working, and the radiator fans come on full blast the moment you start the car because the temperature can not be read. I have read online forums where others are having this same exact issue. Resetting the codes seems to temporarily fix the issue, but it comes back within roughly 2 weeks. This vehicle has not even reached 60k miles yet.

The shifter does not always engage and the car will remain in gear and can't be turned off. The safety issue is the vehicle rolls forward and backwards at times. I have hit my riding lawnmower under my carport because it continued to roll when in park. I have reported an issue in 2018 and in August 2019 a repair was performed and again in 2019 a gear shift assembly was replaced, It has been confirmed there is an issue with the shifter by a tech servicing my car when he drove it. It is at the dealer now 07-24-2023 to determine the issue and repair. Shift to park will come on inconsistently, however it will roll forward without the message.

When shifting into park, getting a Shift to Park error. Have to jiggle the shifter to get the car to turn off. Sometimes it won’t turn off. About a month after purchasing used in 2020 my wife put the car into park in our drive way, the car rolled backwards with my son in it and the passenger side door open. The passenger side door hit a tree and folded the door backward toward the body. Door had to be replaced. Luckily no one was injured. At the time we did not know about the shifter issue. Secondly our transmission has now gone out with only 80k miles on the car. This is another reoccurring issue that GMC has ignored with a know manufacturer default in the transmission.

Vehicle transmission does not recognize what gear it is in, a potential danger. Warning light appears randomly "shift to park" and vehicle will not shut down. Vehicle does not recognize that it is in park. Requires multiple attempts to manually shift gears. Multiple complaints for this issue found online. Contacted GM Customer Assistance and they are unresponsive to this problem. GM would not reimburse me for the repair and would not recognize this as a manufacturing problem (supposed to send $100 coupon to dealer, good for 1 year?) see 2 attachements

Shift to park error code along with several other error codes including no remote detected that have continually and intermittentantly appeared since my car was at 16 K miles. My car has been in the shop over 10 times and these problems continue to return. my car won't shut off correctly, and this drains the battery. On 2 different occasions I was locked inside my car, unable to start it. Both of those times the outside temperature was over 100 degrees, and I almost had to break my window to exit and survive. I frantically pushed several buttons, trying to start the car, and luckily something tripped so I could open my car. The dealership replaced my battery twice before 31 K miles. They have replaced 2 different fobs when the car didn't recognize them. The dealership has replaced the transmission control assembly, the body control module, the fuel injector, the immobolizer control module, the brake control module, and my car has currently been in the shop for over 3 weeks as they may also need to replace the instrument control module and HVAC module due to those error codes. My car is at 46 K miles and has been in the shop 3 different times since 39 K (less than 10 K miles) all for similar problems. Thankfully I bought the extended warranty that will expire in 2 years. Something is draining the battery and GMC cannot or will not address the problem. There are similar documented cases: https://lemonlawexperts.com/gm-shift-to-park-recall-update/#:~:text=According%20to%20NHTSA%2C%20GM%20has,several%20model%20year%20Acadia%20vehicles. and https://gmauthority.com/blog/2020/05/gmc-acadia-shift-to-park-class-action-lawsuit-filed-in-texas/ Please help to make GMC resolve this complicated problem! I now keep a tool in my car to break a window if I ever get locked in. I also keep my AAA membership active as I have had to get my car jumped several times. I do have videos of the problem, but cannot send a MP4 file.

Vehicle went on fire in or near the engine compartment - the entire front end was burned and car is a total loss. I was in the vehicle driving home with my children (a 5 min drive from their school) and we smelled what we assumed was a a fire pit or fireplace burning nearby; we got out of the vehicle, within 90 seconds there were flames coming out of the hood. Car was well maintained and received nearly all service at the RVC GMC dealership it was purchased from. Vehicle was also still under the warranty we purchased.
