I was on a 5 hour road trip home, and about an hour into the trip, my car died. 2017 Volt Premier, built August 2016, Purchased March 2017
I received "Reduced Propulsion" plus the Check Engine light. As I made my way to find the nearest dealership, I received an "Engine Unavailable" notice - likely due to the temperature reaching just above 240 degrees F. I then limped to the dealership on the little electric charge I had, with it running out in their parking lot. The car still charges and still can be propelled by the electric motors. Engine still starts after it cooled off. Fuse # 3 blew, explaining many of the codes. Dealership indicated that they "confirmed" an oxygen sensor must be replaced - as the error still comes up after the Fuse # 3 was replaced. They have not yet determined why the fuse blew. Oxygen sensor is not covered under warranty (attached PDF shows they found an exhaust leak at oxygen sensor?!). I'm still under powertrain and emissions warranty. Approximately 56,200 miles.
Dealership - 4 hours away from my home - is unable to determine why the fuse blew and has been unable to reproduce the failure with in-city driving. They have not yet tried highway cruising - as I suggested they try more than once. I was using cruise control going between 60 and 75 miles per hour when the failure occurred.
I've seen multiple other threads with the same thing - blown Fuse 3, and bad O2 sensor. But, I've yet to find any TSB's which may help the dealer repair. (I've never had a dealer service department actively research TSB's ... I've always had to provide any to them in order to get the repair). Is there a TSB which covers this fuse blowing? Or that covers the EGR blowing the fuse? The dealer is spending a lot of "Diagnosis" time on my car at an hourly rate - my fear is they will conclude it's not covered under warranty and that I need to pay out of pocket for many hours of diagnosis and test drives. My point in posting here is to gather collective knowledge and TSB's or other official GM information regarding this issue.
Attached are the trip record. We stopped at an Oasis / Rest Area, then continued on ... around Gary Indiana the car failed, and I was able to limp it to the dealership in Burns Harbor, Indiana. Long story short, they couldn't repair it due to lack of Volt Tech & it was towed to a different dealer (dealer in Burns Harbor is not working on the car now).

I had to take a $100 uber ride (cheaper than taxi), and a $300 one-way car rental to get from the dealership back home, so I could get to work the next day. We were supposed to be home by 9pm, and didn't get home until 3:30am. I was advised this is likely covered under the GM Trip Interruption coverage, as I was more than 100 miles from home.
Please help - I need my car back, and must immediately drive it 4 hours home when I pick it up from the dealership - after driving 4 hours to get back to the dealership (8 hours of driving). I can't have it break down on my drive home with the same issue because they can't reproduce it - and won't repair it without reproducing it.
