Crankcase (pcv) problems of the 2010 Volkswagen Passat

I have owned this car for beraly one month. 2 days after purchasing the 02 sensors went bad. 1 week later my pcv valve went bad. And 2 days after that my car stalled on me while driving down a canyon and would not start again. I lost control and ended up on the side of the road. I though I was going to kill myself. After sitting there for about an hour the car turned on but was extremely shaky and would stall the minute I slowed down or came to a stop. I managed to get the car to a repair shop only to have the engine die on me. The car cannot be turned on or moved. I was told it might be the timing chain which is a common issue in this engine. I'm being told I need to practically replace the engine which will cost more than what the car is worth. If I try to turn the car on. It hesitates a lot and once it turns over it immediately shuts off. I have beraly made 1 payment on this vehicle and it already died on me. Was excited about such a nice looking car only to have fall under the lemon car category in my opinion. I am now left with a car payment. A huge repair bill and no mode of transportation all due to Volkswagens faulty design.

While driving home (approx 50 mile trip) I heard a loud screeching noise from the engine area. I was traveling on a highway at about 60mpg. I pulled over, turned off the car and saw smoke and smelled burning from under the hood. I opened the hood and smoke billowed out of the back of the engine bay. I looked under the car to see if it was leaking anything and found a large amount of what seemed to be oil dripping from the car. I then noticed a trail of oil from before I stopped the car. I left the car in place for a tow to not damage the vehicle anymore than it already was. It was towed to the vw dealership in town where they diagnosed the problem is that the pcv valve stopped working correctly, which caused the rear main seal to fail and become completely destroyed. They said that the entire engine needs to be taken out to replace the seal and is going to cost $1700. Vehicle did not have any indication of problems before the screeching noise and did not have any check engine light come on during the problem. Vehicle has just over 100,000 miles and vw of America denied to help out in anyway when contacting customer service. Another incident with exact same issue was found when I looked at open claims on NHTSA and many other claims are easily found with a simple google search. I have had all maintenance performed on time and at vw dealerships and was never advised to get the pcv replaced as normal maintenance.

Pcv valve failed, at some point prior to Jan 11, 2016 and 77,748 miles. No warning lights or other indication of the failure ever occurred until the pcv valve failure cascaded into failure of the engine rear main seal (between the engine and transmission), resulting in a massive oil leak. Based on a web search, this is an extremely common situation, not only for the valve failure, but the method in which it first becomes apparent to the vehicle owner (rear main seal failure). Cost to repair was over $1900. Pcv valve failed again at some point prior to oct 24, 2017 and 116,102 miles. Similar to the first event, no indication of the failure occurred until this cascaded into an upper timing cover seal failure. Cost to repair was over $600. My research clearly indicates vw pcv valves are known to be trouble-prone. Vw extended the warranty on pcv valves to 10 years/120,000 miles on certain vw models (including Passats) up through 2008 model year. My experience, and the experience of other owners, certainly suggests 2009 and 2010 vw Passats still have this problem, and one has to wonder why these model years are excluded from the extended warranty, especially considering the outrageous costs that owners are left to deal with.

Pcv valve went out; and in turn, the rear main seal ruptured a major oil leak between engine and transmission. Dealership concluded the pcv position crank valve cause back pressure into the crank resulting in damaging the rear main seal. Vw has issued an extended warranty on pcv on certain models causing this issue, but the tsi 2009 and up have not been included in this recall. This issue could result in a catastrophic engine failure due to all oil leaking out of car while on road. This occurs when pressure builds up to pcv fails when car is being operated.
