Have a new 2022 Denali - Since I've had it there has been a rattle coming from drivers side lower dash - could be underneath truck- like a rattling heat shield or cable rattling against the fire wall - on top of this its intermittent! Not sure how this can be - sometimes is louder than radio - sometimes subtle - sometimes loud then just stops - Very frustrated - I did have one of the heatshield clip service bulletin completed but didn't fix issue - Anyone out there have same issues?
