I have had a 500x since June and for the first few weeks everything ok .First thing I noticed was a little rattle while driving in low gear / speed I thought at first that it was pinking so ignored it but it has got worse over time . I'm not sure if the other noise I identified is linked or separate but when driving at around 45/50 miles a buzzing noise starts and will stop if I increase or decrease in speed . I now have a warped dashboard where the two pieces join just above the infotainment screen . I'm guessing it's from the screen heater . Has anyone else experienced any of these problems ?
