I actually think the latest data from our resident tester @4xeRubicon (thanks!) points to an electric motor overheating. So far I haven't had this issue on road, but definitely did while wheeling it on a moderate trail. Youtubers have ran this same trail in electric without issue and I'm all stock, so I don't think it's working as intended.Just came across this and read the whole thread. Interesting research. I have a 4xe on 37's and have recalibrated it with a Tazer JL. I live in Northern CA and regularly drive in high temperatures. I have never had this issue. I mostly drive around town but if I do drive highway I get 18 or so miles on electric only at ~60 mph before the normal transition to hybrid mode. I think:
- The data you compiled makes a compelling case for this being heat related
- Those having this issue clearly have a problem, this is not a feature forced on all those with larger tires.
- Possibly your jeeps are not circulating battery coolant effectively?
I'll be wheeling it again on Saturday and will run JScan to monitor temps this time. I forgot to bring my code reader on the last trip.
