Hi,
Just got mine (GS3 01) 3 months ago. Has been very good only, had rattling problems with the sunshade and right mirror both replace by dealer at no charge under warranty. So far no problems.
Factory warranty is 4/50,000 yrs/miles basic and 6/70,000 powertrain. In my experience, they have been very good with warranty service.
Loaners have been provided for major service and when they are available.
Good luck
