My 2020 ram 1500 limited has 5k the problem started at 1k. When I start my vehicle and when accelerating it has rattle noice from passenger rear side. Brought it to dealership, at first they told me it's normal noise due to air suspension pump is pumping air. Went back second day and test drive it with tech, he stated he is not sure what it that noise. Dealership called an hour later stating that it's normal noise again but due to EGR valve is working. Called my two buddies who own 2019 ram limited, they don't have any rattle noises. Called dealership service manager and left voice mail, ofcourse there is no response. Does anyone has same rattle noice from passage rear side, sound like exhaust issue? Thanks.
