NHTSA Complaint #11666987 — 2021 VOLKSWAGEN TIGUAN

The oil separator in this vehicle failed resulting in other additional damages at 46,000 miles. I was not given the oil separator, upper timing cover, or lower oil pan for inspection. All maintenance in this vehicle was done timely and only touched by the VW dealer. The manufacturer warranty ended 17 days before the component failure. VW agreed to pay half for the repairs that were quoted at 1600 dollars because the warranty expired by time so closely and was under on miles. The service advisor at the dealer reached out to VW about this on his own accord before updating me on the issue because he told me that this exact component has been happening very frequently with this model/year and didn’t think this should be happening at such low mileage. This component failure rapidly causes other serious damage resulting in very high repair bills on the vehicle. The check engine light came on over the weekend (6/7) and the car was brought to the dealer Tuesday (6/10) and was driven about 75 miles between the light coming on and the car being dropped at the dealer. The diagnosis quoting email from the dealer: “the vehicles oil separator failed and caused excess crankcase pressure to be put on the plastic components of the engine, mainly the upper timing cover and lower oil pan. That pressure causes the components to crack and leak oil, which is what happened” this resulted in a quoted 1600 dollars in repair. This is very concerning. I believe that an oil separator going bad at 46,000 miles in a perfectly maintained car as per recommendations of the dealer is unacceptable. I am reporting this in hopes that a recall from the manufacturer will be forced as this is unacceptable at such low mileage and the part needs to be replaced by another manufacturer with better quality.
