I wish I saw this post earlier. I have two 2020 Macan S vehicles. I noticed door handle hair-line cracks after 1 year in my White Macan. I fortunately found that it was covered by Porsche warranty by doing a little research. I sent pictures to my dealer who said they had to send it to Porsche for approval of free replacement. It took a while but it was approved. It took longer to get the part and then to get it painted. I think the dealer was lax in the process along the way too. I dropped off the car and it took a few days at the dealer but they replaced all 4 handles. Not sure why it took so long if it was already painted, but I asked for and got a a loaner during that time. In the meantime, I looked closely at my Dolomite Macan and found cracks there too. I repeated the procedure, with all the follow ups and delays. I am scheduled to bring the car in for fixing in 2 weeks. Not sure why the dealer is lax with this since I am sure they get reimbursed by Porsche for the trouble. In any event, if you have a Macan, you should check out the handles real carefully and then contact the dealer if you see cracks. Get all 4 replaced (they probably do this automatically) since they will probably all crack eventually. Not sure what the issue is, maybe the paint finish, but it seems to be a known problem. I haven't heard of this in any other Porsche model.
