2017 GMC Acadia

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.

When putting my car into park and turning the engine off. The car will not turn off and displays a shift to park error. The car has to be turned back on and shifted to a different position then put back in to park to try to turn engine off again. Often times this needs repeated several times before the engine will actually turn off.

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.
