I have 98,000 on my Yukon XL Denali and I have a crack in the piston block as I was told by the dealer. I have an Endurance Car Warranty on the vehicle and the vehicle has been at the dealers since [XXX]. The warranty company is giving the dealer the run around where they have torn down the motor already twice to prove to them that there is a crack. Plus, there was no warning signs other than it not running smoothly as it has been and that is why it went to the shop. Nothing should be happening to this motor at 98,000. The vehicle is presently at Palm Chevrolet in Ocala, Florida and Scott Kelly is the service manager. Can you please give me some advice.

This car had catastrophic engine failure due to the lifters, push rods and camshaft. This car make and model and engine type is notorious for these specific parts to malfunction. This could have left myself and my children stranded on the interstate. The vehicle has been inspected by a certified master technician with ASE training. They confirmed that these parts are a common issue with these cars.

UNINTENDED SURGE OF ACCELERATION. WILL HAPPEN RANDOMLY ABOUT ONCE A WEEK WHEN UNDER SLIGHT ACCELERATION. IT FEELS LIKE THE ACCELERATOR GOES FULL THROTTLE FOR ONE SECOND, CAUSING A HUGE SURGE OF ACCELERATION, ALMOST PLOWING INTO THE CAR IN FRONT OF US MULTIPLE TIMES. THE LAST TIME IT HAPPENED WHILE IN REVERSE. DEALER EXAMINED THE CAR AND SAID THERE ARE NO CODES STORED IN THE COMPUTER AND COULDN'T REPLICATE THE PROBLEM. WE GET THE CAR BACK TOMORROW AND MY FILE DRIVES IT WITH OUR 4 KIDS, SO THIS IS VARY SCARY (FOR THE SAFETY OF OUR FAMILY AND OTHERS ON THE ROAD). DEALER SUGGESTED IF WE DON'T TRUST THE CAR, WE CAN HAVE CAMERAS INSTALLED IN THE CAR TO CAPTURE THE PROBLEM SO WE CAN SHOW THEM. WE HAVE VERY LOW CONFIDENCE IN THIS CAR AS IT IS DANGEROUS TO DRIVE. THE FIST TIME WE NOTICED THIS WAS IN THE AM, SO THE ENGINE WAS STILL COLD. STARTED ACCELERATING SLIGHTLY DOWN OUR RESIDENTIAL STREET AND THE CAR WENT TO FULL THROTTLE ON IT'S OWN FOR ABOUT 1-2 SECONDS (RPMS SKY ROCKETED). THE SECOND TIME WAS ABOUT A WEEK LATER WHEN MY WIFE WAS DRIVING THE KIDS TO SCHOOL IN THE MORNING (AGAIN WITH A COLD ENGINE). SHE PULLED OUT OF AN INTERSECTION AND THE HEAVY SUV WENT TO FULL THROTTLE ON ITS' OWN AGAIN, ALMOST CAUSING HER TO LOSE CONTROL. THE PROBLEM PRESENTS ITSELF ABOUT ONCE OR TWICE A WEEK. THE LAST TIME SHE WAS BACKING OUT IN REVERSE WHEN THIS OCCURRED, CAUSING HER TO ALMOST CRASH INTO SOMETHING. DEALER CAN'T FIND THE PROBLEM BUT THE PROBLEM EXISTS. THE ONLY THING IN COMMON BETWEEN ALL OCCURRENCE IS THAT THE ENGINE WAS COLD, THE AC WAS ON, AND THAT WE WERE UNDER LIGHT ACCELERATION WHEN THE SYMPTOM PRESENTED ITSELF.
