2010 GMC Yukon Engine Problems

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.
