2017 Porsche Macan Engine Problems

Porsche is making use of aluminum fasteners for important engine components. These fasteners are substandard for the service. At 100,000 miles, two of the bolts for the timing chain cover simply broke in half during normal service, resulting in a substantial oil leak and an expensive repair (about $3000). At 120,000 miles, one of the bolts for the valve cover also simply broke in half, resulting in another oil leak and a repair bill of about $1000.

The 2017 Porsche Macan S is unsafe to drive on the road as the vehicle goes into jerking mode while driving without any warning, the safety light came on as transmission fault. I took the vehicle to River Oaks Porsche, and they diagnosed the issue as transmission problem common with the Macan brand and the Cayenne brand, I then informed the manufacturer, and I was informed that since the vehicle had not been recalled there was nothing they could do with the defect. Since the dealership acknowledged that the issue was common with these brands, I believed that these vehicles should have been recalled for public safety.

The engine oil started leaking on the timing case over bolts. The current mileage is 20500. This happened right after the regular 40,000 mile maintenance. The dealership said it's out of warranty but on a bit of research the aluminum bolts seem to break easily with a lot of similar cases.

On April 26 2021 performed routine oil change and noticed oil leaking from valve cover gasket onto side of engine. Took to Prestige Imports Inc, in Lakewood Colorado April 30th 2021, mileage is 22,851 and dealer told me: "Inspect for engine oil leak, no leak present although a slight wetness is visible at valve cover, no drips present. No repairs necessary per Porsche warranty guidelines." Dealer advised me to drive car hard and return in few weeks for visual inspection. Returned to dealer on 05/19/2021 and dealer looked at car and told me leak was a SWEAT and would not be repaired under warranty. Car purchased 05/22/2021, out of warranty 05/22/2021.

PER PORSCHE DEALER, "2 BROKER BOLTS ON THE TIMING COVER CAUSING AN OIL LEAK." VERY, VERY EXPENSIVE (THOUSANDS OF DOLLARS) TO REPAIR AS VEHICLE IS 50 MONTHS OLD. NO RECALL JUST YET BY PORSCHE PER DEALER, THOUGH HAS AFFECTED PORSCHE CARS WITH THIS ENGINE IN SIGNIFICANT NUMBERS AS IS READILY NOTED ON ONLINE FORUMS AND ACKNOWLEDGED BY DEALER.
