Thanks for the reply. The Challenger and the Jeep both were 3-4 months old when I picked them up off the lot. In both cases I had to replace the wipers on cars with 3 miles and 7 miles respectively because they had formed to the windshield park position and didn't flex anymore. The Jeep was leased during the COVID shutdown in Michigan and so I literally parked it from April to June and barely drove it. Then I was driving my convertible until September when I traded it on the Challenger and drove it while the Jeep sat.Replaced the battery under warranty, everything is fine now. Resting Voltage is King on these things...LOL!!!⚡⚡😎
Maybe my battery on the Challenger needs to be topped off. The Cherokee is being driven daily at this point and I haven't had this issue since I started driving it full time. I also haven't had a day with a warm evening in a while either so maybe I will need to have the battery checked at my first oil change.
Either way, I think all the current FCA vehicles are extremely resting voltage sensitive and the ones with ESS and one battery more so.
