One problem related to battery dead has been reported for the 2018 Jeep Wrangler. The most recently reported issues are listed below.
I have a push to start 2018 Jeep. The other day my car wouldn't start, battery died on it. It was fixed but then the ac/heat unit won't turn on at all. While looking for solutions I saw this issue was very common in 2018+ models and was wondering why there isn't recall on this if it's a electrical issue within the vehicle.
