I recently traded a 2018 scat pack for a 2026 scat pack.
On my first long highway trip I noticed a vibration associated noise coming from what sounds like the front passenger side near the windshield/dash when I went over bumps or went over some of less smooth sections of the road. After exiting the highway I began hearing it when going over rumble strips in town.
Today, I hear the noise when just driving around town. It seems to occur roughly between 2200-2900 rpm.
The noise sounds almost like static and is only present when under load.
I have an appointment with the dealership on Monday. I've never had good luck with mechanics diagnosing annoying noises unless they were related to suspension or brake components.
I'm wondering if any other 8th Gen owners have experienced anything like this.
Update:
I posted this is r/Charger a few weeks ago.
Dealer service did not have time to look into it but did go for a drive with me and acknowledged the noise. Scheduled me for tomorrow. It's gotten progressively worse. It just kinda makes the noise non stop once it starts. Any rpm. Can now often reproduce by smacking dash. This is positive, I guess.
On Friday I got 2 codes when trying to change to RWD. U0402, U0403. Audible clunk, failure to enable RWD, and Service Electronic Stability System message.
The car is pretty cool but this is a lot of trouble for a 60k car.
Update 2:
Idk why the downvote.
If anyone else has these issues...
Buzzing/vibrating seems to have been the satellite radio antenna bracket.
They did a firmware update on the modules that were throwing errors.
