I have also noticed a large drop in fuel mileage. I traded in a 2022 3500 High Country for a 2024 3500 High Country. I am hopeful once the engine breaks in that the mileage will improve; The 2022 did improve over time but it was not this drastic. 2022 - Highway speeds on level ground with 60,000 > miles on the truck would average 28-30MPG 2024 - Highway speeds on level ground with 5,000 < miles on the truck now averaging 15-17MPG

1) Loose Drivers mirror, when hitting sharp bumps it looks like the mirror is going to fall off. 2) Low Speed rattle coming from passenger side, only occurs from speeds between 50 - 60kph. Plastic or thin metal tapping/flapping sound. Kicking truck into neutral and changing RPM does not effect the noise. I have taped off all exterior panels and inspected. Starting to think its drivetrain.. 3) Started yesterday - Boost tube type medium/higher pitched growl noise around 2300RPM under load. Sounds to be coming from passenger side. I don't believe its related to the #2 issue.
