“Currently I have two issues I believe my 2018 Wrangler jl to be experiencing. The first is a constant clicking noise coming from the undercarriage of the vehicle, mainly in the rear. This occurs at slow speeds (10mph or less). The dealer replaced my rear axle but to no avail. The second issue is that I do not believe I am able to fill my fuel tank to the proper capacity. ( have a 4-door jl) from 'low mileage' warning to full, typically I get about 16 gallons.”
