Mine had to have the exhaust headers replaced as I had the same issues as you (cleaning and greasing etc did not work)
Also I had to have the Throttle replaced (that was within a month of ownership)
And now its in today having its big service and needs the entire rear suspension replaced
Thank fuck I have warranty as its £1400 for the part alone on the rear suspension
2019 GSA with just short of 12k on the clock....
Jesus.... i hope my news is better
