2019 GMC Acadia

I just purchased this vehicle and within a day, it was already giving an alert that something was wrong. Says "action required, shift to park". My car was in park. It was not shutting off due to the notification, which leads your battery to drain. The next day, as I was driving with my kids, the headlights start flickering, and then shut off. It left us driving in the dark and nearly causing a wreck because someone didn't see us coming because it was too dark. The dealership said they look at it, so I don't know what will happen moving forward. It's definitely not safe unless the issue is addressed.

The contact owns a 2019 GMC Acadia. The contact stated that while the vehicle was idling and shifting into park(P) the “Shift to Park” message was displayed. The contact stated that the vehicle was in the park(P). As a result, the contact was unable to turn off the vehicle. The vehicle was then taken to the dealer where it was diagnosed; however, the contact was not informed of the result. The vehicle had not yet been repaired. The manufacturer was notified of the failure, but no further assistance was provided. The failure mileage was approximately 34,000.

2019 Acadia originally displayed a shift to park message at 12K miles and vehicle was still under warrantee. New shifter harness was installed and a wire harness jumper added. GM covered the cost of repairs. At the time I was told hopefully the repair fixes it but a chance it won't and will need to bring it back in. Two years later at 36K miles it occurred again but was out of bumper to bumper warrantee so GM would not cover and dealer would not give any discount. Both the dealer and the GM claim rep I talked to were not able to adequately explain why this is not considered in the powertrain warranty which is still valid. GM did reimburse 50% of the cost of repair but I am still out ~$380. This issue seems well documented across numerous models / years of GM products.

The electrical and gear shift failed, causing a problem that GMC calls “shift to park.” Even when the car is placed in park, the car does not recognize that it was placed in park and cannot be turned off, preventing the driver from leaving the running car. This is a known problem that multiple dealers are aware of and there even appears to be a recall and lawsuits on the 2018 Acadias. However, on my 2019 Acadia, which has the same problem as the 2018 vehicle, this is a problem that costs hundreds of dollars to fix. This should be recalled because it renders the vehicle a safety hazard because it cannot be turned off and it is a known GMC problem that they refuse to fix.

The contact owns a 2019 GMC Acadia. The contact stated that after the transmission was shifted into park(P), the “Shift to Park” message was displayed. The contact shifted the gear shifter into several other gears and was able to turn off the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and confirmed that there was no recall associated with the VIN. The failure mileage was approximately 60,000.

Vehicle has been bucking and jerking when trying to accelerate. Going up a hill is scary (especially with my kids in the car) because it slows the car down trying to find a gear. Dealership says it's a torque converter but since so many Acadia's are being recalled for transmission issues, we feel ours should be included as well. Dealership is making us pay for a transmission flush which doesn't make sense because if it weren't for these issues, we wouldn't need to have a flush.

I have the shift to park error where my car is not recognizing that it is in park and will not shut off. I have been held hostage inside my car, late for work, etc because my car will not shut off because it is not registering that it’s in park. Also, my breaks are unbareably loud with whatever switch they made to the “new” brake material.
