2018 GMC Acadia

Rear right hand lower suspension control arm broke in half, after further inspection it looks to have been separated from its original factory form which then cause uneven load on the arm causing it to fracture in half. The factory form separation seems to have been ongoing for unknown time due to surface rust is visible at the factory mold separation, where it snapped in half there is no surface rust. Fortunately it happened when I was only moving the vehicle to make space for another, the broken arm cause the wheel to turn to the right as if it was making a right hand turn and I can't imagine if it would have happened while driving in the city of even worse on the freeways... It would be a certain crash and safety for us and those driving around us. Last photo is from Amazon listing, I did order the part from another source that is a factory GM part and I am doing the repairs of replacing this myself as I am mechanically inclined. Thanks

When I put my vehicle in park, the message “shift to park” pops up. It has been doing this for well over a year. I have already had to replace a battery once due to this because I didn’t realize it was still on. It does not happen everytime I park but at random times. The more it happens, the longer it takes for it to go off. At this point, I can only hope my car is really in park. I jiggle the shifter, hit the “ +|- “ on the shifter and have to turn the vehicle off and on about five or six times. Eventually it will go off. It took me 20 minutes today for it to go off in 100 degree heat. The vehicle’s AC is not running when trying to get the shifter to go off. It keeps the electronics running but not the AC. I keep waiting to receive a recall on this vehicle because of this issue but still nothing. I have noticed there is a recall for this but not vehicle. I have already replaced one battery due to this issue and do not want to continue to replace batteries and worry if the vehicle is really in park or not.

My 2018 GMC Acadia has had the "Shift T Park" alarm and indicator going off after my car is turned off and in "PARK" It only happens intermittently, but frequently enough to be annoying. The dealer and GM told me because my VIN wasn't in their recall range, they would not honor the recall. This has been happening since I purchased the car in 2018.

Battery saver ignited comes on and and the entire dash flickers and turns off ! This happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! And we don’t know where it is coming from . Now shift into part light comes on !
