First problem is the trunk door. About a week ago I was getting something out of my trunk and accidently hit the button and the door started to close so i tried to get away from it and somehow my arm got caught and there is absolutly NO sensor to stop the trunk from crushing my arm. Unforunately, i did have some injury to my arm from the trunk coming down and have pictures of the brusing on my arm. A sensor to stop the trunk from closing on a body part or anything for that matter needs to be better made or put in the vehicle. I took pictures of my arm days later because i was in to much pain to take them when it happened. It was not a fun injurying. Saturday night iced it, sunday had to have it elevated because it was so swollen, didnt take the picture until Wednesday when it finally had calmed down. There is bruising and swelling still on Wednesday. this happened July 9th Second problem i recently had an issue with my wiring i guess it was. Specifically it was reduced engine power message displayed and my engine stalled out on me. I was told that this is a common problem with Buick Enclaves, Chevrolet Traverses, and GMC Acadia's which is the car i have. Being that this is a common issue wouldnt this be something that would be concerned a RECALL? i dont know how recalls so im more curious about it. my car stalled out on me in the middle of traffic on July 16th

"TAKATA RECALL" ON TUESDAY JUNE 19 I HAD PULLED INTO MY DRIVEWAY JUST BEFORE MY GARAGE WITH MY TWO SMALL CHILDREN. I PUT THE CAR IN PARK AND GOT OUT TO UNLOAD AND PREPARE TO TRANSFER MY ONE KID AND THEN THE OTHER. IT WAS 100 DEGREE WEATHER SO HAD TO KEEP THE CAR RUNNING. AFTER A MINUTE OR SO BEING IN PARK, MY CAR BEGAN TO DRIVE FORWARD WITH NO ONE BEHIND THE WHEEL. MY CAR DROVE OFF MY RETAINING WALL AND LANDED VERTICALLY WITH MY CHILDREN SUSPENDED IN THEIR CAR SEATS. EMERGENCY OFFICIALS RESPONDED. I HAVE VIDEO AND WILL HOLD OFF FIXING THE DAMAGE OF VEHICLE SO THAT THE FEDS CAN INVESTIGATE. GMC ALSO WOULD LIKE TO TAKE A LOOK AT IT. PLEASE LET ME KNOW WHERE TO SUBMIT MY SECURITY FOOTAGE.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 GMC Acadia Denali verdict →
