I replaced the canbus module in April are you saying replace it again?
Interesting. How often do you drive it? If it sits a lot or you only use it for short trips that will be a problem for the batteries. At least every other week, you should take it out and put 20 or more highway miles on it.

Also, did you charge the new batteries to 100% before installing them? Often they will lose quite a bit of charge while sitting on the shelf. This is especially true of the aux batteries, which are not rotated out of inventory as often. What size batteries did you buy and what brand?

It's my daily driver so it's gets use every day. I did not charge the new batts just installed & turned the key. Looking back you are absolutely correct I should have charged fully first. The main batt I went with Optima DH6 & the aux was something else less memorable. Both were direct replacement spec's (or greater) than OE.

For what it's worth, the clockspring can fail without the actual cable inside it failing. Normally when these go bad none of the steering wheel controls work like horn etc.

The module itself can still be going dead on the network which would cause your issues. I'd suspect a loose terminal somewhere at this point causing an intermittent loss of communication. Could be a power, ground, or bus wire. I'd suggest a dealer at this point, as you're most likely going to get into some really deep intermittent electrical diagnostic work.

Back to the drawing board. My Wrangler is still having these episodes including loss of power steering. I gave the vehicle to my dealer for a week and supplied them with the attached TSB. They drove it & naturally it never failed for them. Sadly this TSB lead was a dead end. They charged me nothing as they feel like they didn't fix it. I still love my local dealership (Reed JCDR)& will not give up on them. For now the next thing they suggested was to go through the vehicle & check all ground connections and the estimate is about $1000. I took my vehicle back for now as I missed it :) & I'll probably give it back to them at a later date for another try. I'll certainly report back should we figure it out.
