Great idea! Tapping into the rearview mirror’s power is a neat solution, just be careful not to short-circuit anything unless you're feeling extra adventurous. A pro might be the way to go if you’re unsure!
Yikes, that’s a total nightmare! Definitely not the dream car you were hoping for. Sounds like your dealership’s customer service needs a serious tune-up too! Hopefully, Jeep steps in and gets this sorted for you soon!
I live in New York, and I’m getting around 13 in the city, 15 mixed, and maybe 17 max on the highway. I’ve got 5 passengers if that counts, so pretty much the same as you even with the bigger L version. Looks like yours is doing a bit better
