I have had 3 Macans, all since new - 2015 Turbo, 2017 Turbo PP, and now a 2023 GTS. They ALL leak if it gets hot enough, and believe me at 100+ for the last 3 months in Texas, it doesn’t take long sitting outside for it to leak. Under more “normal” temperatures, not an issue.

I had the “fix” done on my first one and it was a waste of time - made absolutely no difference. This is a “feature” that seems to keep on giving. Minor problem on an otherwise excellent machine. Just keep some glass cleaner and a towel handy if you have to have it out when it is really hot.

 

I had issues like this when i picked up my 2023 in May. It's lessened a bit after the local dealer diluted the solution put in by the factory/delivering dealer. I would make sure you are not using anything like rainx etc. only use water based windshield fluid was the recommendation. You could drain as much as possible and replace and see if that helps. In my case my local dealer is not where purchased so they wanted to charge labor time to address.

 

Attempting to assign new car service charges that address a problem to the owner seems totally inappropriate.

 

I wonder if this could be due to ambient temps rising and WS washer fluid tank expanding.

 

Greater ambient temperatures causing the problem wasn't my experience.

Mine was dribbling during usage for a short while during the spring, but summer usage at higher ambient temperatures has not caused the problem to reoccur.

totally agree. I made them make it go away

 

I’m glad I found this thread because I thought I was going crazy when I kept finding the dribbles on the rear window of my recently purchased 2018S. I’ll have the dealer check it out when I bring it in for its first service and ask about the replacement spray jet.

 

So good to stumble upon this info. I live in a hot climate and this issue drives me nuts.

 

Update since I started this thread: dealer way back when replaced the pump and issue was gone. I was living in the NYC area at the time so climate was not so harsh and my car was 90% garaged. Issue never recurred. I moved to FL last year (I know, one of those..) and the issue has come back. One of the likely reasons is the car is not garaged here and under direct sun for good parts of the day. But like I said, it took for me to move here for this issue to come back again, 4 years later. I'm well out of warranty so will have to let this slide this time.

 

Hi, my name is Greg and I made a quick video on my fledgling youtube channel "tiafo! Garage" with a repair that worked for me for this issue. I plan other content for other Macan repairs- the next one up is the leather dash lifting. (In addition to the content on my 1972 Ferrari Dino and 1972 Porsche 911S, plus bay area car events/lifestyle).

Hope this is helpful and that you enjoy it!
