Vehicle states, 'shift to park, ' when trying to turn off engine when it is already in park. Turn vehicle back on and have to shift multiple times out and then back into park before car will recognize it is in fact in park to shut down entire engine. Have replaced battery once already. Vehicle is stationary and foot is on break when trying to turn car off. Has been happening since purchase but, just got fed up with it.

I have requested at least 4 times for repair of my car 2017 Acadia. Several caution light on the dashboard comes on including the engine sensor(malfunction indicator lamp). While driving the car it looses power to accelerate. When pressing the gas pedal the car stalls. This issue has happened on both the highway and city. There have also been times when turning into a parking lot I have felt some vibration. Additionally, the car dashboard gives out commands for putting the car in park after it is stationary.

I went to a local dealer and complained about a vibration/rumble while driving. It happened mostly around 1200-1700 RPM. The service manager heard of the problem. There was a manufacturers bulletin outlining the problem and suggesting a fuel management software upgrade. This was done. The bulletin also applied to Cadillac XT5, which is on a shared platform with my 2107 GMC Acadia denali AWD. There are now several new RPM ranges when the vibration/rumble occurs in addition to the old 1200-1700. Not only has the old problem re-appeared but there are certain conditions about 1500 RPM when I am starting out from a stop for about 50 feet where the problem seems to almost stall out and then with a big clank (like down shifting or transmission is slipping and then suddenly engages) and takes off. I cannot help but think there is going to be a mechanical breakdown of something due to the sudden engagement and clank or even stalling out in traffic, if this problem is not fixed. I contacted the dealer once again but have not heard back yet.

Truck constantly fails to start. Keyfob not recognized. Computer system crashes, rear air vents fall out. Faulty gas tank and gas line. Cannot fill up gas tank past 1/2 a tank. Been happening since inception and is constantly in and out of service for the same issues over the past year. Not being able to start the truck is a safety hazard to me and my family. There needs to be an alternate way to start the truck should the computer system crash.
