If the first thing you tell people about your vehicle is how good the gas mileage is...you don't like what you're driving...ijs. I love my Jeep and doing Jeep things... LoL!!
I have a 2021 Jeep Gladiator Mojave with 4,500 miles that is making an intermittent whining noise...the sound is similar to microphone feedback or speaker feedback. It's not the radio and initially it'll start whining when I reach speeds of 45+mph and after about an hour driving it happens more...
