2015 CHEVROLET SPARK EV Electronic Stability Control Esc Problems

CONTEXT: IT WAS A WET EVENING HERE IN PORTLAND, OR (8:15PM PDT, APRIL 13TH) AND I WAS GETTING NEW TIRES THE FOLLOWING WEEK, SO I DIDN'T CARE ABOUT THE LONGEVITY OF THE TIRES. ALSO, WHAT I EXPERIENCED WAS SOMETHING I READ ONLINE BEFORE BUYING THE SPARK. I MADE A LEGAL U-TURN TO GET TO THE ENTRANCE OF FRED MEYER (A KROGER STORE) AND HIT THE ACCELERATOR HARD ENOUGH (~60% THROTTLE) TO SPIN THE TIRES AND THE TRACTION CONTROL ACTIVATED.

THE WARNINGS AND LOSS OF BRAKING ASSIST MAY STAY AWAY FOR A PERIOD OF 1 MINUTE OR UP TO 1 WEEK OR MORE. IT APPEARS TO BE VERY RANDOM. FORTUNATELY, NONE OF THE OCCURRENCES HAVE RESULTED IN A CRASH, BUT THERE HAVE BEEN SCARED DRIVERS AND PASSENGERS. THIS IS THE SECOND TIME THIS PART (THE DEALER BLAMES THE BPMV AND IS NOW PUTTING THE FOURTH ONE ON MY CAR) HAS BEEN AT THE DEALER. THE SECOND ONE WAS APPARENTLY LEAKING WHEN INSTALLED. THIS WORK WAS PERFORMED AT MOMENTUM CHEVROLET IN SAN JOSE, CA. THE...
