Valve spring snapped clear in half inside the engine while driving on the highway. This caused me to be stranded on the side of the road in the middle of the Arizona desert with my two dogs in the heat. Thankfully I did not lose control of the vehicle. No warning signs whatsoever until out of nowhere- vehicle check engine light started flashing as well as 'service stabiltrak' and 'traction control disabled'. I immediately pulled over. Thankfully I shut off the engine in time to prevent further damage to the pistons. Vehicle was towed and inspected by Holden's Auto Service in Kingman, AZ. Valve spring broke clean in half and was given to me after valve spring was replaced. Compression tests were performed after valve spring replacement. engine was run until warm and normal compression resumed. No other mechanical issues found. Checked for recalls on this vehicle. nothing found related to this.

Error Codes: B0052:00 Deployment commanded; B0015:04 Driver seat belt buckle tensioner deployment loop open; B0022:04 Passenger seat belt buckle tensioner deployment loop open. I have a police report but it exceeds the 10mb limit.

SINCE 2016 THIS VEHICLE HAS HAD THE DASH CRACKING, RECENTLY THIS ISSUE HAS GOTTEN MUCH WORSE. THE DASH IS LITERALLY ABOUT TO FALL IN. THIS HAS HAPPENED MOSTLY DURING TIMES IT WAS SITTING ALTHOUGH DRIVING HAS DEFINITELY MADE IT MUCH WORSE. I'M CONCERNED THAT IF THE AIRBAG DOES HAPPEN TO GO OFF IT'S GOING TO THROW SHARP PIECES OF PLASTIC FLYING THROUGHOUT THE PASSENGER COMPARTMENT. ANOTHER ISSUE I HAVE FOUND IS IF I SET ANY PAPERS ON THE DASH THEY FALL INTO THE DASH. I CAN NOW SEE THE WIRING INSIDE THE DASH BECAUSE OF THE MISSING PIECES. ON TOP OF THIS YOU HAVE TO BE CAREFUL TOUCHING THE DASH AS I HAVE BEEN CUT ON SEVERAL OCCASIONS FROM THE SHARP EDGES CREATED BY THIS ISSUE. THE CENTER OF THE DASH APPEARS TO BE ON BORROWED TIME IT HAS SUNKEN NEARLY A HALF AN INCH WITHIN THE LAST MONTH. THE DEALERSHIP CLAIMS THIS IS JUST NORMAL WEAR AND TEAR FOR THE VEHICLE AND REFUSES TO FIX IT WITHOUT ME FOOTING THE BILL. THIS JUST SEEMS OUTRAGEOUS ON A CAR PRICED NORTH OF 60K
