2014 GMC Acadia Engine Problems

Engine randomly shuts off when driving for no reason. Will restart and check engine light comes on. Has now happened three times , twice to me in traffic. One of those the car went into a limp mode where it wouldn't drive above 30mph at most. This is very unsafe in the middle of highway traffic. The second happened approaching a traffic light , I put the car into neutral and luckily it restarted and check engine light came on. The third time my wife had her friends in the car and it shut off at a light , she had no idea what to do. I had her stay there and brought her our other car. I have read this is caused by a known fuse box issue. They should be made to fix this problem before someone gets seriously hurt driving in traffic.

While driving at 70mph legal speed limit the engine lost all power and ability to brake or steer with and power assistance, mechanic has since told me the timing chain failed and destroyed the engine. Vehicle had aproxmitly 99k miles on it and in good repair. No warning that it was going to fail and was told that this is a common failure with the engines in most gmc / chevy / buick mid size svu.

THE VEHICLE SHUTS DOWN WITHOUT WARNING AT VARIOUS SPEEDS. FROM 5MPH-70MPH. THIS HAPPENS ERRATICALLY AND WITHOUT WARNING. IT RESULTS IN AN IMMEDIATE LOSS OFF ALL POWER.

I WAS RETURNING FROM A DOCTORS APPOINTMENT AND STOPPED TO PICK UP MY SON'S PRESCRIPTION. I TURNED TO CHECK ON MY SON, WHO JUST TURNED ONE ON SUNDAY, AND SAW HIS FACE WAS EXTREMELY RED. I WAS CONFUSED BECAUSE HE WAS SO WARM AND I HAD THE A/C ON BLAST. APPARENTLY THE BACK OF MY NEW DENALI ACADIA 2014 WAS NOW ONLY BLOWING WARM AIR. I SHUT OFF THE REAR AIR ROLLED DOWN THE WINDOWS AND FULLY BLASTED ONLY THE FRONT A/C UNIT. I LIVED ONLY 3 MINUTES AWAY SO I RACED HOME AND GOT HIM OUT OF THE VEHICLE. AFTER A FEW MINUTES HE WOKE UP AND STARTED TO APPEAR HIS NORMAL SELF. I WENT BACK OUT TO THE VEHICLE AND RETESTED THE REAR AIR NOT WORKING. AFTER I CONFIRMED IT I CALLED THE DEALERSHIP WHERE I PURCHASED MY VEHICLE. I HAVE BEEN LOOKING THIS ISSUE UP ON THE INTERNET AND IT APPEARS TO BE QUIT COMMON. WITHOUT MY MOTHERLY INSTINCTS AND FORMER TRAINING MY SON COULD HAVE POSSIBLY DIED FROM HEAT INJURIES IN MY BRAND NEW VEHICLE. I AM EXTREMELY DISAPPOINTED THAT THIS IS EVEN AN ISSUE I HAVE TO ALSO WORRY ABOUT. GMC NEEDS TO GET THIS ISSUE RESOLVES BEFORE SOMEONE DOES LOSE THEIR CHILD(REN) TO THIS HEAT ISSUE.
