2016 Volkswagen Tiguan Transmission Problems

Your 2016 Tiguan TSI is experiencing severe carbon buildup in the engine despite having only 84,000 miles, which required intake manifold replacement and now needs a full engine cleaning and all four fuel injectors replaced at a cost of $3,296. This buildup can cause engine misfires, power loss during acceleration, poor fuel economy, stalling, and potential catalytic converter damage. The repair involves professional engine decarburization and fuel injector replacement to restore proper engine function.

Your 2016 Tiguan is leaking oil due to a failing head gasket, which requires a $4,109 repair. You're just 241 miles over the 60,000-mile powertrain warranty limit, but a mechanic believes the leak started before you hit that mileage based on the oil's appearance and location. You've maintained the car properly with regular oil changes, and VW says the warranty doesn't apply because you had an independent shop diagnose it — though your mechanic disputes this. The repair will likely involve removing the engine head and replacing the gasket.

Oil consumption issue. “Normal” oil consumption is 1 quart per 1200 miles according to VW. My Tiguan with 70k miles is burning 3 quarts every 2,000 miles. No obvious oil leak or burning of oil. I’m told I need a new engine and this is a known issue for VW. Car no longer under warranty after 60k miles.
