NHTSA Complaint #11383455 — 2017 CHEVROLET VOLT

PRIOR TO STARTING MY 1,100 MI TRIP WITH MY 2017 VOLT PREMIER, I INFLATED THE TIRES, CHECKED FLUIDS, & CHARGED THE CAR. THE MONTHLY DIAGNOSTIC REPORT I RECEIVED THE DAY BEFORE MY DEPARTURE INDICATED NO PROBLEMS WITH THE CAR, WHICH HAD APPROX 40,500 MI. I WAS DRIVING ON INTERSTATES & HIGHWAYS USING HOLD (GAS) MODE, OCCASIONALLY MOUNTAIN MODE. APPROXIMATELY 275 MI. INTO THE TRIP I RECEIVED POWER PROPULSION REDUCED ALERT. AFTER AN ADDITIONAL 50-75 MI I RECEIVED AN ACTION REQUIRED: ENGINE OVERHEATING REDUCE SPEED ALERT. I EXITED THE INTERSTATE AND PROCEEDED TO THE NEAREST DEALERSHIP TO DETERMINE IF IT WAS SAFE TO CONTINUE ON MY TRIP. I WAS TOLD THAT THE PROPULSION ALERT WAS NOT AN IMMEDIATE CONCERN & THAT THE OVERHEATING WAS LIKELY NOT RELATED. I ALSO RECEIVED A GM DIAGNOSTIC E-MAIL STATING THERE WAS AN EMISSIONS PROBLEM THAT SHOULD BE SERVICED WITHIN 7 DAYS, BUT DID NOT BECOME AWARE OF THIS E-MAIL UNTIL A DAY LATER. APPROX 200 MI LATER, I WAS ON A REMOTE, UNLIGHTED HIGHWAY WHEN I RECEIVED AN ENGINE UNAVAILABLE ALERT AND LOST POWER. MY CAR QUICKLY DECELERATED, BUT I WAS ABLE TO GET TO A NARROW SHOULDER. I TIRED TO PUT THE CAR IN PARK, APPLY EMERGENCY BRAKES, AND SHUT THE CAR DOWN BUT IT WAS DIFFICULT TO TELL IF THESE FEATURES WERE WORKING. I PUT THE HAZARD LIGHTS ON AND WAITED FOR A CHP OFFICER DUE TO LACK OF CELL SERVICE & HIGHWAY SAFETY CONCERNS AT NIGHT. AFTER 3 HOURS, ALL SYSTEMS FAILED, INCLUDING LIGHTS. ONLY MANUAL LOCKS WORKED. AFTER TWO 30 MI TOWS TO GET TO A DEALERSHIP WITH A VOLT TECH, IT WAS DETERMINED THAT A BAD EGR VALVE WAS CAUSING A FUSE TO BLOW,. THE VALVE WAS ORDERED (TECH REMARKED THAT THE PART IS "POPULAR") & INSTALLED. THE ISSUE SEEMS TO BE FIXED. BUT, IT IS UNCLEAR IF THIS IS A DESIGN FLAW, MANUFACTURING FLAW, OR A ONE TIME OCCURRENCE.
