The contact owns a 2017 GMC Acadia. The contact stated that after shifting to the park position and attempting to turn the vehicle off, the engine shut off but the headlights and dashboard lights remained illuminated. Also, on multiple occasions, the battery had drained and the vehicle had to be jump-started. The vehicle was taken to the local dealer who diagnosed that the floor shifter harness was faulty and needed to be replaced. The floor shifter harness was replaced and the failure was remedied, but approximately two years later the failure reoccurred. The vehicle was taken back to the local dealer.

Service side detection system warning is on and upon investigation and diagnostics it has been widely reported as a common issue that GMC only chose to address for a select number of vehicles. I have 93k miles and there is a service agreement to 80k. Others have indicated that it not fixed it can send bad signals to circuit board causing battery failure, information system failure, dash light failure and headlight failure making this a safety issue is something like this occurs in the dark. As a result I am concerned for my safety and am frustrated that GMC is not required to fix this issue.

1. Could not put car into park or turn off. Caused battery to be dead as it would not turn off when put into park. 2. Steering wheel locked and jerked repeatedly. Could not turn into parking spot. The steering wheel had a mind of its own and could not stop the jerk. It is dangerous and scary ! 3. At night, the headlights do not light the road. It is as though there are no lights at all. It is dangerous to not see the road at night because headlights do not give appropriate lighting.

Head lights are very dim making driving the vehicle at night very unsafe. Took vehicle to gmc dealer, tech said that head lights are within gmc specs. Too insane to drive this vehicle at night an accident or even death can occur.

With vehicle stationary, I attempted to place the transmission in "park" and turn off the vehicle. The dashboard information screen displayed the message "shift to park" and would not allow the vehicle to fully shut down (headlights remained on) even though the shift knob was in "park" as well as "p" displayed on the dashboard screen. The electronic emergency brake was inoperable and the vehicle seemed to be at risk of rolling away. This left me stranded with the vehicle and unable to remove myself from it.

The car will not turn off and reports on the dashboard display 'shift to park' even though the shifter is in park. Truck will roll when it shouldn't be possible. Also, unless you can get it to acknowledge you're in park, headlights and all accessories stay on. An alarm sounds if you leave the vehicle. It's a mess and although gmc knew about the issue in mid 2018, refuses to fix it without payment. This should be a mandatory recall.

The vehicle has had ongoing issues since it was purchased in june of 2017. The 'shift to park' problem had to be fixed twice, the emergency braking system engages itself for no apparent reason which has almost caused several accidents, the horn does not work when needed in emergency situations, the headlights are so dim it's dangerous, the battery has drained and left my wife stranded 4 times, and the vehicle has a very rough idle and it almost stalls out. I attempted to work with gm to have them take the car back early (lease) and the request was recently denied. This is my 3rd acadia and it by far is the most dangerous car I have ever driven. I am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. I do not feel safe having my family in this car and I am requesting your assistance to help me work with gm on a resolution. I entered the date that the vehicle first started to have issues, there have been over 20 incidents over a 2.5 year period causing a safety issue or leaving my wife and children stranded.

Exterior headlights are ineffective and unsafe while driving at night. Poor lighting on my vehicle has caused near accidents on the freeway with deer and stalled vehicles on the on the road.

My 2017 gmc acadia has a "shifter" problem. I put the car in park but I get an error message that states "shift to park" and the car doesn't completely turn off even though you turn the car off physically. Some electronics stay on like the radio and headlights. You cannot completely shut the car down - again - even when you physically turn the car off. The car is in park and stopped.

From purchase to date, the headlights are terrible in good weather. In bad weather its very hard to drive safely in this vehicle. Visibility is severely limited for the driver at night.
