Starting vehicle after 10 hours of vehicle not running, the vehicle cranks/has a delayed start for approximately 4 to 8 seconds. Battery, alternator and start was check and all was in working order. I was told the issue may be a defective fuel pump, due to the engine losing fuel pressure after not running for an extended period of time.

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.

I attempt to place my Acadia into park and power down my vehicle only to get a "shift to park" error message. I am unable to power down my vehicle and not fully park my vehicle even though I have parked it. This occurs daily and has occured 15-20 times in 1 attempt to park. I have to attempt to turn car back "on" and then put car into drive or reverse driving about a foot or so than attempt to repark my vehicle. Only to have to repeat this step over and over til it finally disappears. GMC customer service associate claims they are unaware of the issue. Of course this issue only occurred after my vehicle warranty expired.

In order to clear the problem, the vehicle must be restarted and the shifter moved between gears and back to park, sometimes several time before successfully shutting down. Dealer said that even though the car had only 35000 miles on it, it wasn't covered under warranty as the vehicle had been in service more that 36 months.

Between 1300-1500 RPM there is a hesitation for acceleration. It seems the transmission shudders at this RPM at different speeds. This will be the second time the vehicle has been to the dealership with this complaint. The 1st time this occurred the technician reported the car was several bulletins behind and was brought current. This did not resolve the issue. If anything the issue became more noticeable. A brake sensor and gas pedal assembly have also been replaced due to defect.

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.

- Holland, PA, USA

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.
