2017 GMC Acadia

The 2017 GMC Acadia has a known problem when shifting to park. The computer system does not acknowledge the vehicle is in park. It requires numerous ways to get the vehicle to acknowledge it is in park and shut off: 1) Turn the motor on and off and shift from drive to park continuously until acknowledged in park and shuts off (waste of time, gas, and effect on the starter and ignition) 2) Bang down on the console shift knob 3) Pray This is a known problem with Acadia 2017 and 2018. Why has this issue not been addressed for a forced recall by GMC. If you take it to the dealer to fix it is very expensive and their original problem. this is a safety issue shifting from drive to park continuously when stopped. This is not good to have to do especially for senior citizens who might inadvertently drive forward or in reverse when simply trying to stop.

The contact owns a 2017 GMC Acadia. The contact stated when shifting the gear into Park, a warning message indicated to place the vehicle on park, but the vehicle was already in the Park position. The vehicle was taken to the dealer for diagnosis and was installed with a jumper harness. It was unknown if the repair rectified the failure. The manufacturer was contacted, and they stated that there was no recall associated to the failure. The failure mileage was 120,000.

When I place car into park I get "Shift to Park "message .... I am unable to turn off or leave my vehicle .... I am worried that as this problem has increased over the past 3 months that I will be stuck on the road or elsewhere .... the dealers say they are aware of the issue but no permanent fix or recall has been issued by GMC .... I understand that other owners have the same problem .... also with different years not just 2017 .... PLEASE help me with this problem as I always travel alone & am afraid of something terrible happening while on the road .... Thank You in Advance .... Laura Schwalbe .... laroc325@aol.com

The car says “shift to park” even when it has been put in park. The car could potentially not be parked and cause damages to people or objects. I’m not sure if it’s Been confirmed by dealer but plenty of people with the same car have reported this incident. This car was purchased within the last year clean title, no issue until the past couple weeks. Car is at about 44K miles, only driven on weekends and occasionally to the store during the week 5-10 mile radius.

When vehicle is put in park (dash reads park) the vehicle is not detecting the vehicle in park and vehicle will not turn off. It takes multiple attempt moving the gearshift into other gears and then into park before the vehicle registers a "park" and able to turn off the vehicle. If you take your foot off the the break, vehicle doesn't move when park gear not detected. Safety concerns include parking in garage and not realizing the vehicle has not turn off and possibility of CO2 or if a child would get in the vehicle possibly being able to engage the gearshift into reverse or drive. This happen 3 out of 4 times when placed in park.

Loss of power steering: bought NEW late 2017: In 1st month a whining noise was present while turning the steering wheel in any direction (driving or in park) even when slightly turning the wheel. At the time, didn't seem to effect anything. Difficulty started around 80k miles & continued to get worse as time went on. Each time varies on type of turn, speed of turn, how long the car has been in use. On average: it starts (& continues to get worse) after the first 10/15 minutes of driving. Loss of steering comes & goes (not only happening while turning) for at least 4 -15sec. In the last year (mid 2021 - 2022) went to mechanic -couldn't find an issue. Husband checks fluid levels monthly (no changes/no leaks are visible ). As of May 2022 (130k miles) turning into parking lots/spots/driveways/etc I have NO power steering, my husband is barley able to turn the wheel during these events. Its unsafe to drive. Doesn't seem to be as bad if speed is 20mph or faster. Shudder issue (maybe @60kmiles): *We had this issue w/our 2012 Acadia too. Multiple GMC Certified mechanics have been used to correct this. Only one mechanic was able to witness the shuddering. All things tried have failed to correct it. First started happening between 35 - 55mph (now its at any speed: 10 - 80mph), speeding up used to make it shudder less, turning traction control off USE to make it shudder less. Plenty of forums abt this issue including all things tried & failed. No resolution. Shudder causes car to not accelerate at times. RPM jumps high & bounces around. AC would stop working (started @20k miles) it makes an air releasing noise when AC is in use. *2012 Acadia did this too. Adding Freon helps for limited time. No leaks. Mechanics "CND", its still not fixed. "Tighten fuel cap" warning comes on randomly. When checked, its tight. Automatic start fails randomly, since day 1. "Ck Engine" light comes on & off randomly. Main issue was the shuddering *Reporting date used for loss of power steering.
