2021 Volkswagen Tiguan

VW dealership diagnose by 2021 VW Tiguan with a cracked oil pan and timing cover. The cause was from excessive oil pressure from a failed PCV valve which cracked the plastic oil pan causing excessive oil leak. This occurred driving on the highway and the ECP light on the dash came on with a message "max epinine rpm 3000". Vehicle quickly slowed down and was extremely sluggish to maintain a safe speed with other traffic. Dealer was able to see cracked oil pan and oil leak from timing chain cover and read error codes pointing to the issue. Can physically see crack in oil pan. Oil spilled out from oil pan onto ground when tow truck moved it. Dealer produced a video of the issue and visual see the cracked oil pan and leaking timing chain cover. ECP light and engine max speed error was displayed while driving on the highway. From my understanding, basically the PCV valve fails and it over pressurizes the crankcase. It can cause the gaskets to fail causing leaks or the oil pan to crack which in our case the oil pan cracked.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving at an undisclosed speed, the contact noticed blue smoke coming out of the exhaust pipe. There was no warning light illuminated. Additionally, the contact stated that the vehicle was experiencing excessive oil consumption. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.

I purchased the Tiguan just shy of 2 years ago. Since 12/17/24 I have spent over $2,000.00 in that short of time because one incident the oil leaked out in a matter of a day. The second incident, while traveling from St. Louis to Tulsa, the oil light came on every 80 miles because the oil had spewed out. I had to replace the oil about 5 times that day. The third incident came 1,500 miles later. I came out of a restaurant in Claremore, OK and saw every drop of oil had spilled out into the parking lot. Each time I took the car to Autohaus. They only work on Volkswagens. He has been doing so since he was 14. If he can't fix it, no one can. I can't afford to keep dishing out $700 every 2,000 miles.

At only 38,200 miles the dealership found shards of metal in my engine. The only solution is to replace the entire engine and my car just passed its warranty 5 months ago. I have kept up to date with services and driven the car responsibly. There is also another 2021 VW Tiguan owner in my town and her car did the same thing at only 29,000 miles! She was still under warranty so the engine was replaced but she now states that it burns through oil at a concerning rate. One day the engine like just turned on, then the car goes into a “limp” mode and doesn’t exceed 3000RPM.

The upper control panel housing failed. My safety was put at risk because while driving the panel randomly dropped from my ceiling, blocking my rear view mirror and surprising me. The vehicle has not been looked at by the anyone else other than myself. There are many documented cases online from people experiencing the same kind of situation. There were no warning lights or symptoms that this was going to happen.

At about 60,000 miles a VW dealer told me it was normal for VWs to use oil. Now at 80,000 I have a $2,000+ bill b/c the PCV is faulty and the timing cover has failed. I did NOT get a low dngine oil warning, but mechanic says panic wait it was low ( oil change 4,000 miles ago). This could have led to a seized engine on the interstate. I am upset to learn this is a common problem with this vehicle. It is an expensive repair. From other posters I fear this is not the end of the problem. VW should recall this part .
