Just flipped 40K on my 2020. Added 15 ounces. Glad I read this thread. Never had to add coolant to any vehicle Ive ever owned. Im 50, and have had many.
2020 JL from the dealership in VA. Dealer lift, new Fuel 18 in wheels, New 35" Grabbers. 52K price tag. Mint condition black. Could have bought multiple Sahara's at other Dealers in town but would have had to do all the above, not under Warranty and a pain in my a$$. I wanted a used Sahara...
