I was a long time VW owner before buying our first Mazda, current 2020 CX9. Previously bought six VWs from the same dealer from 2000 to 2020, including two for my son and daughter. Cars were religiously serviced by same dealer. Our most recent 2015 Jetta and 2015 Passat both started using oil at around 50k miles, a quart every 2k miles. Both had the same 1.8T motor which is now known for this issue.. Dealer said VW won't do anything because their threshold is one quart for every one thousand miles. When they both started burning a quart every 6-800 miles, took back to dealer to resolve issue. Long story short, VW corporate answer was I'm out of luck because cars were now too far out of warranty. I traded both in our 2020 and a 2021 CX5 for our daughter. Like stated above, lots of manufacturer non-support stories out there.....not just Mazda.
