2021 Volkswagen Tiguan

Upon starting my 2021 Volkswagen Tiguan, the vehicle immediately went into "limp" mode and the check engine light and EPC light came on. The vehicle would not drive over 18 mph. The car was towed to a close by Volkswagen dealership and checked for codes using a multipoint inspection. The report came back with a throttle body issue (Multipoint inspection report attached). The throttle body was replaced and the vehicle was taken for a 15 mile test drive. During the drive, the same problem occurred. After the drive, 34 codes were found in VWs report. I have also attached the report to this complaint. The technicians at the VW dealership didn't understand the problem, so they opened up communication with Volkswagen in Germany. The Volkswagen engineer advised the dealership to replace the wire harness. After the wire harness was replaced, the car has no more issue (although it has only been 5 days since), which cost $2314.54 in total. There is a class action lawsuit in the state of New Jersey (Case [XXX]) against Volkswagen Group of America that states "VW is aware of concerns involving faulty wire harnesses"... affecting 2019-2022 Volkswagen Atlas, Golf, Jetta, TIGUAN, and Taos. Thank God that this happened to my vehicle with the car was at rest and not traveling at a high rate of speed that could have been fatal.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving approximately 55 MPH, the check engine warning light illuminated. The vehicle was not diagnosed or repaired. The contact stated that on three separate occasions, while the vehicle was parked, the contact observed oil on the ground underneath the vehicle. The vehicle was then taken to a dealer, and oil was discovered under the vehicle. The vehicle was diagnosed, and determined that the breather failure caused the crank case pressure to enter the system, causing the upper timing gasket and seal to be compromised and leak oil. The contact was informed that the oil separator timing cover, CAM magnets, and oil pan needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 50,000.

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.

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.

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 .

volkswagen vehicles have a real serious problem that can cause your car fails in the middle of the road, and it is the oil separator. A failing oil separator can lead to poor engine performance and potential damage. It will cause a massive oil leak that will damage others' engine components, and the car can stop working at any moment, and it can be a dangerous situation. The most affected vehicles are Volkswagen tiguan. Please investigate this problem because a lot of people are dealing with this dangerous situation.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving 65 MPH, the accelerator pedal was depressed, and the vehicle failed to respond. The contact stated that the vehicle was losing power and was unable to drive uphill. The contact also stated the engine was consuming an excessive amount of oil; however, the dealer had informed her that the oil consumption was normal. The check engine and electronic power control (EPC) warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the turbo cylinder and timing chain needed to be replaced. The local dealer was contacted; however, the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 200,000.

My 2021 Tiguan suddenly lost power causing my wife and daughter to be stranded. Car was not drivable and lost both oil and power. Towed to VW dealer and was diagnosed with a faulty pcv/oil separator causing excessive crankcase pressure. This party failed once car warranty was over costing almost $2000. Prior to the car stranding them they had to drive at less than 25 MPH on the Long Island expressway. oil was leaking from the upper timing cover seals. VW Dealer removed and replaced oil pan with gasket, pov and upper timing cover seals. filled o i l to correct level,road tested vehicle and rechecked and no leaks at this time. All this damage occurred by no fault of our own. I have learned thru my research that this is a common problem on the VW Tiguans. All has been repaired and replaced as you can see from the receipt attached. Prior to the party failing multiple lights lit up on the dashboard forcing my wife to pull over and get out of. harms way until someone could come and get her.

Engine oil light came on and car was down about 2 quarts of oil AGAIN.
