What 639 owners told NHTSA about the 2017 GMC Acadia Limited

GM issued Special coverage N192210240 for repair/replacement of the evaporative emissions purge valve because it may not fully close. The special coverage states that the dealer is to replace the part at no cost to the customer as necessary until 150,000 miles or 11/12/2026 whichever occurs first. Since owning the vehicle in question I have had this particular part replaced three (3) times, approximately every 20,000 miles. Each time this particular part fails my check engine light is illuminated, my vehicle stalls immediately after refueling, my garage and home quickly fill with emission fumes upon starting the vehicle, and the vehicle idles rough when stopping. The GM dealership replaced the part the first 2 times it failed at no cost to me stating that it was covered under GM Special Coverage, but the third and most recent time refused to honor the special coverage. They, instead, stated that I had to pay $189.99 for a diagnostic in addition to the cost of the repair despite the fact that my vehicle was still within the special coverage parameters and the special coverage bulletin states "as necessary" . The dealership stated that the special coverage was only a one-time use, and I was to pay for repairs each additional occurrence. There is clearly an issue with this part, and GM has acknowledged that by offering the special coverage. This coverage should be valid for the entire time stated because this is clearly a faulty part.

My car on has 54,000 miles on it. For the last two weeks it has started showing that it is not in park when it actually is and continues the warning until I have shifted back and forth at least 4-5 times to clear the message and then able to exit the vehicle. It will roll forward or back to some degree even though it seems to be in park but it messages that it is not. When calling our dealership they do not show a recall and state it will be $180.00 just to look at it, not counting repair for this. there have been no other warning in the system and no accidents at this time. I do have children that ride in this car and could cause a serious situation if the car were to roll or be in gear.

My Gmc although not listed on the recall list has been effected by the "shift to park" issues that plague these vehicles. I was out of town and was unable to shift my vehicle safely into park without warnings that my vehicle wasn't secured. I had to disconnect my battery when I had to park in order to prevent roll back and endangerment to other. I took my vehicle for repairs and was told it was a common problem and nothing can be done but pay out of pocket. Why? It has the same issues as the others? Why can't I be recompensated for a recall issue? I have records to show it was the gear shift control and all other.

The "shift to park" warning light comes up every time I put my car in park. I have to move it back and forth multiple times to get it to acknowledge that its in park or the vehicle will not shut off. This is a dangerous situation in that the car could easily roll when I am not in it. I know that this is an ongoing issue with the 2017-2018 GMC Acadia and don't understand why GMC won't issue a recall for this. If this were to cause injury or an accident then they are 100% liable. I started having these issues about a week ago. My husband took it to the dealership and they told him that its not a recall or under warranty. I cannot afford to fix this myself at this point.

GMC has been unresponsive in servicing the recall for this vehicle as of 10/08/2024. Local dealers indicate they are waiting for parts - related airbags for servicing the recall. As a result, the car is not able to be sold for a fair market value. It is a 2017 model and we are being impacted financially by the issues with this recall and parts that are still unavailable.

NHTSA ODI 11618691

The transmission in the car failed. These failures are a known problem with this vehicle and while attempting to get assistance from GM, they refused to offer any assistance, compensation or otherwise. I understand the transmissions in these models are part of a larger inquiry. I would like to be compensated for having to have the transmission completely rebuilt after less than 7 years of ownership. GM has known and willingly decided not to repair these. While outside of warranty, this is clearly a design and manufacturing flaw.
