NHTSA Complaint #11309133 — 2019 CHEVROLET BOLT EV

I HAVE A 2019 BOLT EV (MILEAGE APPROXIMATELY 10K) THAT AUTOMATICALLY SHIFTED GEAR TO "PARK" MODE FROM THE "L" MODE AND SLOWED TO AN ALMOST STOP WHILE I WAS ON THE HIGHWAY AT RUSH HOUR DRIVING APPROXIMATELY 65 MI/HR. I WAS ABLE TO SAFELY STEER THE CAR TO A MEDIAN AND CALL ON STAR AFTER REPEATEDLY SHUTTING POWER OFF AND BACK ON AGAIN. I WAS ABLE TO CONNECT WITH ON STAR FOR LIVE DIAGNOSTICS SHOWING A FAILURE IN THE HYBRID CONTROL PROCESSOR (P0A78). I ARRANGED FOR THE VEHICLE TO BE TOWED TO THE NEAREST DEALERSHIP AND HAS BEEN UNDER REPAIR FOR THE PAST TWO WEEKS. GM SENT THE DEALER A "CONTROL MODULE" AS REPLACEMENT BUT THIS DIDN'T FIX THE PROBLEM. RECENTLY, THE DEALER CALLED TO INFORM ME THAT THE TRANSMISSION WILL BE REPLACED BUT NEITHER THE DEALER OR GM PROVIDED A ROOT CAUSE FOR THE FAILURE. GM HAS NOT PROVIDED ANY INDICATION WHETHER THIS IS AN ISOLATED OR KNOWN ISSUE, HOWEVER, I GATHERED FROM PUBLIC FORUMS THAT OTHER BOLT EV OWNERS HAVE EXPERIENCED SOMEWHAT SIMILAR UNEXPECTED SHIFTS IN GEAR TO PARK.*DT*JB
