Open the full vehicle complaint log (all categories)OIl leak from "Brocken aluminum bolts" that do not hold up and are failing to hold up from basic car use. A safety recall on this manufacturing parts issue should have been mandatory back in 2015. When this issue started and Macan 2015-2022 all have this issue and are now been replaced with steel bolts. It is costing consumers $2000-$8000 in repairs do the safety issues of bad manufacturing of bolts used . [XXX] Sounds similar to the fiasco with the 958.1 gen Cayenne V8s using aluminum bolts for the Variocam adjusters in the engine which eventually resulted in a NHTSA mandated recall due to the bolt heads sometimes shearing off and causing all sorts of nastiness (my Cayenne Turbo had this recall). Of course the Cayenne's instance of using inappropriate aluminum bolts/fasteners resulted in much more serious consequences \than a just slow oil leak/seepage as is the case as its not been totally documented with the Macan V6s yet , but not good in either case. <sigh> should have recalled on all V6 MACANS also! A partial repair was done by Porsche in Sep 2023 and in [XXX] I have another oil leak from another aluminum bolt breakage .
