2017 GMC Acadia Electrical System Problems

When shifting vehicle into park and turning off the ignition switch a notification shows up and says shift to park even though vehicle is already in that position.

Dash states put in park. But in park, car would deplete battery which I replaced but didn't fix. Unsafe as manuel states car can shut down while driving to preserve battery. Only 23,635 miles. Mostly parked. Parts $57 with $378 labor!

Shift to Park warning comes on when the car is turned off and it is in park. When we park the the car and shift the car to park and turn the car off the warning "shift to park" comes on and the electrical systems will not disengage. The radio stays on, the car can not be locked, and the doors ding loud alarms if you try to exit the car. The only fix is to sit in the car for several minutes and flick the switch under the gear shift and hope that the shift to park warning eventually goes off and you can exit the car. It sometimes takes 8-10 minutes for this to happen. This first happened intermittently and now happens every time we turn off the car. It has been replicated in a dealership and service center. The independent service center that did our brakes said they were aware this was a common problem in GMCs and they experienced it. We have been told it is a microswitch and the repair option is not under any kind of recall or warranty and up to us to pay for the full repair even though it seems there are thousands of people online experiencing the same problem and paying hundreds of dollars for this fix.

Thermostat Issue (Steering Assist is Reduced Drive with Care) have changed this sensor 3 times in the past 3 years, there is no excuse for that. The emergency braking almost cause me and my daughter to be hit by a train when my car emergency braked while going over train tracks. this is unexcusable

Vehicle will not shut off, keep showing shift to Park, even when vehicle is in park with parking brake engaged. This has been a common occurrence and I see where people discuss a recall, but one is not available for my VIN.

Pulled into a parking space, put the car into park and tried to shut the car off. The warning system said I needed to shift to park. I was in park but could not shut the car off because the car thought I wasnt in park. Took 15 minutes of shifting from park to all gears and shaking the gear shifter before it finally let me shut the vehicle off. This is now the second time this has happened and ive had to have the same thing repaired. They are replacing the whole shifter assembly. Error reads SHIFT TO PARK. This is happening every few years now and at almost 1000 dollars to repair and only lasting a year or so, this is ridiculous.

While driving get notice lane departure not working and thermostat registered zero, when code scanned, states low thermostat temp and able to reset with code reader. Will reoccur in minters to days later. This is an electrical issue to to the ability to reset with a code scan tool, but also a safety issue since it also effects the electrical safety ability associated with the sensor.

Seeing the intermittent shift to park messages when the vehicle has been shifted into park and the ignition is turned to the off position. Shifter wire harness jumper & transmission controls A malfunctioning shifter raises fears of potential rollaway accidents, even if such cases remain rare. For anyone who has to park on a slope, this fear can cause serious worry. Yes, there is a service bulletin (19-NA-206) No, this is 1 of the only problems I have had with this. The other issues I have had is the clear coating on the rims are peeling

Backup camera often does not have a clear picture. Very grainy and static.

WHEN I STOP AND PUT ME CAR IN PARK IT USUALLY GIVES A WARNING SHIFT INTO PARK

Shift to Park light remains on after you’ve put the car in “park” which could potentially run the battery down. Car does not recognize when it is in “park”. Have to “jiggle” the gear a bit, in hopes that it turns off.

Shift to park appears when vehicle is already in park and the vehicle will not turn off.

WHEN I PUT MY CAR IN PARK I WILL GET A "SHIFT TO PARK" NOTIICATION AND WILL HAVE TO MOVE MY CAR MULTIPLE TIMES TO GET IT TO REGISTER. THERE IS A RECALL FOR THIS EXACT PROBLEM ON OTHER 2017 GMC ACADIA BUT DOES NOT FALL UNDER MY VIN #

I’m just reporting several known issues. First, with code P2138, which I got today at Oreilly after my car started throwing warnings. I used my parking brake briefly and afterwards got the following warnings on my car: “Steering Assist is Reduced, Drive with care”, “Engine power reduced” , “Propulsion Power is reduced” , “Service Parking Brake”. I’ve never even had one of these warnings. I’ve only gotten “shift to park” which is another known & common issue. With this P2138 code, it can affect acceleration and essentially loss of control over it, but seems I suddenly have several issues. Recently the infotainment system is possessed, touch screen stops working, it calls people by itself, beeps and scrolls by itself and is essentially useless. Might as well be driving at 1997 something or other, at least I could play a tape or CD. This is Denali trim at 87K miles. Primarily though I’m concerned with this code, if it’s legit, it is very dangerous. How unreliable and unsafe to not know.

When placed in park a message appears to Shift To Park and the vehicle electrical system stays energized.

After shifting to park and attempting to turn off my vehicle, I receive an “Action Required Shift to Park” error message. I’m assuming the vehicle is in park but I’m not certain and worry about it moving or rolling. It is difficult to get it to turn off by jiggling the shifter and turning the vehicle on and off. At times, I am not able to get it off and then the vehicle will not lock and the battery goes dead. According to my VIN there is not an active recall but brief internet search states there has been numerous reports, recalls, and lemon law returns due to this.

SHIFT TO PARK Warning comes on & you can't lock the vehicle nor will it shut off completely. I've had to start & reverse several times before it engages/recognizes that it is in park. OBVIOUSLY this is a KNOWN issue by reading all the other posts relating to this. Please issue a recall....

The known ‘Shift to park’ GMC vehicle defect could cause vehicle to rollaway and possibly hit someone.

Shift to park error message when vehicle is in park and engine will not shut off. NOT RECOGNIZING MICROSWITCH IN THE CONSOLE. NEEDS A RECALL.

My sound no longer works, the radio is constantly going out now I have no sound, no blinker clicks, no emergency notification warnings, no door chime, nothing.
