Problems with 2017 GMC Acadia ELECTRICAL SYSTEM

Shift to park warning light turns on when car is in park. headlights stay on.

With my vehicle stationary and shifter in the park position, i turn my car off and the vehicle turns off but the instrument cluster says "action required - shift to park". this message also does not allow the day time running lights to turn off and if the lights don't turn off the battery drains if parked for long stretches. i have to turn the car on/off several times before it engages and the message disappears.

Vehicle does not acknowledge that you are in park and will not turn the vehicle off completely. the engine shuts off, but lights and everything else stays on. if you exit the vehicle it beeps and the horn honks.

When i put my vehicle in park and turn it off, my shift to park message comes across and i have to turn my vehicle back on and move the gear from park to something else and back to park. sometimes this has to be done a few times before it will completely turn off.

The vehicle states to 'shift to park' but the vehicle is in park already. the vehicle will not turn off and keeps the battery running. i must start up the car and shift it to drive, then pack to park multiple times before the car recognizes it is in park. this happens every time, but the amount of time it takes to turn on and off to reach 'park' is random.

Shift to park alert appears when car is in "park" and attempting to shut engine off. electrical system stays on with bell chiming until i can restart car and re-shift again into "park". this may have to be done multiple times before alert no longer appears. does not happen every time when attempting to shut off engine, but when it does usually requires multiple restarting/re-shifting to get alert turned off.

When i put my car in park i get a warning that says my car is not in park action required. the vehicle bell continues to ding and will not allow me to lock the car. my fear is getting out the vehicle and it starting to roll not knowing if the vehicle is actually in park. this is very scary not knowing if it is safe to get out of the vehicle.

When i shift the car to park and turn it off, i get a warning on the dash that instructs me to "shift to park" even though i already have. the vehicle will not turn off, and as a result i have to turn the car on and off shifting repeatedly up to 20 times to finally get the car to recognize it's in park. the vehicle is totally unsafe as it will not stay in park!

Shift to park issue as described by others. gm dealer says it needs to replace a $20.00 harness + labor of over $200.00. "service parking brake" issue that randomly presented itself one day. i was unable to use the parking brake. gm dealer had to "upgrade" my ebcm for a whopping $200.00. how does gm think the consumer should have to pay for this. they have a monopoly because they are the only ones that can fix this!

When putting the vehicle into park, an error is displayed stating to shift the vehicle into park, even though the shifter is in p. in order to get this message to go away, i have to move the shifter up and down multiple times. could take up to 20 min to get the error to go away. i can not leave the vehicle until the error is off because the lights stay on and will drain the battery. i also notice that the vehicle rolls a little more after multiple attempts to get error message off. this is concerning that it may not realize its in park and roll into another vehicle causing damage to both or roll away. i took to my dealer and was told this is a 'known' issue and is not covered under warranty, nor is there a recall. i just paid out of pocket for new tires because gm knew the tires placed were 'wearing' too soon based on mileage. now, i am being told i will have to pay about $600 to get this fixed. gm knows of issues and not fixing them is wrong. ...

When shifting the vehicle to park and then shutting off the engine, i get an error message 'action required- shift to park'. the vehicle is already in park! i've had to jiggle the shifter, press the brake while jiggling the shifter, restart the vehicle put in reverse, then back in park, and jiggle some more. the radio and lights (both interior & exterior) will not power off and the door chimes nonstop. this happens randomly and it has been a little over a month since the last incident which occurred two days after i had to replace the battery because i missed the error message heading in to work. the last 2 days my husband has disconnected the battery because nothing will work to power off radio & lights. i've had to replace the battery twice now in a new vehicle leased in 2016. the first time was due to brake recall, my vehicle being the only 2017 gmc acadia denali effected by that recall. the brake lights would remain on because the brake was basically sticking, draining the battery. that issue also disabled the cruise control ...

Upon shifting the car to park and shutting off the engine, the console says, "shift to park". the car appears to roll some. i have not been on an incline to see if it is truly in park or not. it will not allow the electronics to shut off and will not let you lock the car so the car cannot be left when this happens. it has been happening intermittently and today i had to shut off and start the car and drive it 10-15 times before it would recognize it was actually in park.

The car will not recognize or shift to park.. the car will not turn off while the shifter is in park thinking that the car isn't in park. this is a safety issue since you believe it is in park when the car is saying it isn't and will not clear the alert unless you continuously turn the vehicle on and off and toggle the shifter. i have a video of the issue being reported

Our 2017 gmc acadia denali says to put the car in park before turning it off when the car is already in park and engine off. all electronics stay on and will kill the battery.

When parking the vehicle and attempting to shut off, the acadia gives the message "shift to park". the vehicle is clearly in park and i must start the vehicle again and shift to reverse or another position and turn off. the vehicle will not allow me to lock the vehicle and keeps power to the vehicle (draining the battery) until it recognizes that it is indeed in park. this has caused a stall and the vehicle to possibly still be in gear when parked leading to a rolling hazard. has taken as many as 15 times for the vehicle to realize it is in park. general motors has issued a tsb (18-na-297) regarding this issue, but is placing the cost of the fix on the consumer. this is a defective piece of equipment that has started a class action lawsuit.
