Thanks guys, I assume I was in accessory mode and that is why the heat did not work.

OK I picked the car up yesterday with the following diagnosis and repair:

Spark plugs and coils faulty. Full engine diagnostic including compression test (220PSI) and else checked good.

They even left the coding I had done so after leaving I engaged the REX SOC and it worked as it is supposed too! Very happy!

Well drove the car on a long trip the other day and when we needed the REX to do a SOC, it would not run and we got an error message and a CEL. I immediately pulled off the highway before I passed the last charging option and plugged in to a level 2. While charging I started to look at the issue. This time I was prepared though and was able to scan the issue and found 'CYL #1 missfires'. So I cleared the CEL and after sufficient charge to get me the rest of the way home I unplugged and headed out. I hit SOC and the REX fired right up and ran all the way home.

I am starting to wonder if this is just a fuel issue. The car was from California and with the low miles on it, 14K, I am guessing it got little use. For all I know the REX never even got used. So taking that possibility of really old fuel plus the fact that California does not have winter blend and I am at 8000ft in the Utah mountains at -7 deg, I am burning off the tank and refilling. I am going to add some seafoam to the fill up too. So far the REX has fired up every time, so that may have been the issue. I also found a nice 2 gal can that fits the front trunk well for double back up!

I use Power Research PRI-G gas stabilizer. Will maintain the fuel for years. This is what we used exclusively in the Military in back-up generator fuel tanks, and emergency fuel storage, which might see only limited use over two-three years or more.

In my case I will have to use the REX fairly regularly due to our remote location. The closest charging station from us is 30 miles away. So I am not overly concerned with the fuel staying fresh going forward. I just bought a bottle of Techron fuel system cleaner to start and will condition ongoing with Lucas fuel conditioner and lubricant to keep it going strong.

So far with fresh fuel it has not hiccuped once.
