2013 CHEVROLET EXPRESS Electronic Stability Control Esc Problems

VEHICLE GOES INTO ENGINE REDUCED SPEED AND SERVICE TRACTION CONTROL AND SERVICE STABILI TRACK WARNING LIGHTS TURN ON. I HAVE HAD THIS PROBLEM STARTING A WEEK AFTER I PURCHASED MY VAN AND WAS "REPAIRED" ON NUMEROUS OCCASIONS AND THE PROBLEM KEEPS REOCCURRING. THE INCIDENTS HAPPEN WHILE DRIVING AND WHEN STATIONARY WHILE ENGINE WAS RUNNING. THE DEALER REPLACED THE ACCELERATOR PETAL ASSEMBLY A COUPLE OF TIMES AND ALSO REPLACED THE THROTTLE BODY POSITION SENSOR AND THE PROBLEM STILL CONTINUES. THE LAST TIME I TOOK IT IN THE DEALER PUT DIELECTRIC IN THE HARNESS AND SAID I MIGHT HAVE A MOISTURE PROBLEM. THE PROBLEM REOCCURRED AGAIN A FEW WEEKS LATER. I DON'T SEE HOW MOISTURE COULD BE THE PROBLEM SINCE IT STARTED A WEEK AFTER PURCHASE AND CONTINUES 4 YEARS LATER.

THE VEHICLE RANDOMLY AND AUTONOMOUSLY APPLIES THE BRAKES AND CUTS ENGINE POWER WHILE DRIVING. AT THIS TIME THE VEHICLE STATES "SERVICE STABILITRAK" AND THE ICON FLASHES THAT I AM SKIDDING, WHICH I AM NOT (I HAVE VIDEO PROOF OF THIS OCCURING). AFTER 4 TRIPS TO THE DEALERSHIP THE PROBLEM STILL PERSISTS. IT IS ONLY A MATTER OF TIME FOR THIS TO OCCUR WHILE MERGING, OR MAKING A LEFT ACROSS TRAFFIC AND CAUSE A SERIOUS AND POTENTIALLY FATAL COLLISION.
