2017 GMC Acadia

Shift to park alert pops up when turning vehicle off. Vehicle is in park. This prohibits the vehicle from turning off. Per my investigation other gmc acadias made in 2017 also have experienced this which results into either prohibiting them from turning their vehicle off or their battery dying. This is a safety hazard because it increases risk of being stranded due to malfunction.

The contact owns a 2017 GMC Acadia. The contact stated while driving at various speeds, the radio independently switched to different settings. Due to the failure, the speedometer was no longer be visible. The contact stated that the failure caused the driver to be distracted while driving. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 95,000.

Vehicle frequently shows the error "Shift to Park" when I attempt to turn off the car after it is placed in park - which is confirmable via the instrument panel. The vehicle electronics will not turn off until the error is cleared. At times I cannot clear the error and I've had to set my parking brake and leave the car electronics running while I go into a store, which leaves car unsecured and drains the battery. The car has gone into my local GMC dealer for repairs. The first time I took it in (August 2020), I was 365 miles outside my warranty and GMC refused to pay for the repairs. The dealership felt certain a recall would be issued and suggested I have harness switched which they admitted was a band-aid fix and that it wouldn't fix the issue, but it would allow a period where the error disappears (which it did) - until a recall is issued. The Shift to Park error reappeared about 1.5 years later. I took my Acadia back to the dealership and was told they could not replicate the error and therefore there was nothing they could about it. The error is happening much more often and I've scheduled another repair appointment to address the problem.

Went to Burt Watson the end of May. Paid $250 to diagnose 3 problems. Trans was intermittently kicking into passing gear when starting from a stop position, a service engine light and passenger side blind spot warning would come on when nothing was there and other times wouldn't recognize a vehicle was there. Around the middle of July the battery began draining intermittently leaving me stranded at night away from home. The rear defogger began turning itself on and couldn't be shut off and was very hot to the touch. The drivers seat moved all the way forward on its own pressing me into the steering wheel and dash while I was driving at highway speed. Forcing me to change 2 lanes of traffic trying to get to the side of the road.I was told by the service manager that the rear fuse block had shorted out do to water intrusion from bad drain ports. This was replaced, and then I was told something else was draining the battery. And this was "one " of the things not covered by warranty. There is a service bulletin stating that there may be pinholes at the top of the a-pillars and d-pillars yet the dealership stated a new windshield was needed. There are several service bulletins indicating that such leaks can reek havoc on the electronics. The dealership has changed their estimate several times with still no solution in site. The vehicle has been sitting at the dealership since July. At one point it was communicated to me that GM would assist in the cost of the repairs when and if job was ever completed.They are now stating the cost to repair the issues is $5500.00 and is my responsibility.

Shift to part to turn off vehicle but vehicle does not recognize shift to park and repeatedly requires turning the car back on to try to maneuver gear shift until it finally recognizes it is in park and can be turned off. I have had to restart my care 10-20 times before it finally recognizes it is in park and will turn off and unlock the doors. This is a repeated issue that has been going on for at least 6 months but happened again today requiring 17 restarts.

I bought my vehicle in 2020. In 2019, there was a special coverage notice (N172097060) with part repair because of known service side detection issues for water module intrusion. My understanding is this is due to the poor design and placement of the item in the rear of the vehicle that is known for getting water in it when driving, which then impacts the entire electronic system (not just service side detection). Beginning in spring 2023, I began to have these issues, starting with service side detection first. I then had other major electrical issues connected to this issue I believe are a safety concern. I have had very scary episodes at high speeds of my entire car electronic system shutting down, speedometer going to zero, gas going to empty, glitching and not starting multiple times. It got to the point my entire car was not drivable due to this issue - the dealer has a temporary fix on it to allow it to continue to be drivable until parts are in. The dealer has confirmed the issue I am experiencing is this safety special coverage issue from 2019. I contacted the dealer I bought my car from and they stated they did the special coverage fix in 2019. They confirm this issue is occurring again. However, they claim that because it was fixed in 2019, I am responsible for paying and fixing it this time around. The issue was not resolved and I believe this is a huge safety issue that should be a recall, not just a special coverage. It was very scary driving on a highway with my children in tow and having my entire system go out at a high speed. It has been inconvenient, parts are supposedly on backorder and being told it's my responsibility to cover it when it's a known issue. I have also found online many other owners having this issue. The special coverage did not fix it if water continues to get into the module and continues to generate these issues again. I appreciate any assistance on this matter and thank you for your time!

Vehicle will randomly drop into a lower gear which causes the engine to rev up, then a warning light comes on indicating that the steering assist and ABS system are offline. Not what you want to have happen when driving 70MPH on the highway. Problem has been ongoing for ytears and GMC insists it is a transmission problem but another thing I have noticed whenever it happens is that the battery voltage increases. Seems like GMC shipped these cars with weak alternators which would explain the myriad electrical problems this vehicle and others like it have had.
