I have a 2016 i3 Rex with 70,000 miles on the odometer that I mostly use to commute to work 23 miles from home. Most days I have about 58 miles showing on the battery when it is fully charged.

I was on a longer trip (72 miles one-way) and had been using the Range Extender engine on the return trip for about 44 miles when it shut down and it displayed the message that the Range Extender was not available. Luckily, I made it the rest of the way home on the battery.

The check engine light is on and I found miss-fire codes for one cylinder. I've replaced the fuel pump relay, spark plugs and ignition coils.

The Range Extender engine is still shutting down after running a short time.

Any suggestions as to what I do next?
