2021 Volkswagen Tiguan Transmission and drivetrain Problems

“Here is a quick description of the issue from our Volkswagon of Huntington service report. We have had this ongoing issue for a few months now. the check engine light will come on. We get it checked, we replace a sensor, and all is good for a day or week. Then we do it again, replacing a different sensor. Now the dealer is saying the oil separator is leaking and requires repairs starting at $8,400 and going up from there as they uncover more. We have always maintained the car properly. …”

“I’ve had my Volkswagen Tiguen since 2021 fresh off the lot. I have been the only owner of the car at about 30,000 miles my head gasket blew, causing the engine to go into default after weeks in the dealer. They replaced the head gasket and stitched it up, the head gasket blew again at this point I was still under warranty so they agreed to replace the engine. It drove fine after the engine was replaced this year 2025. I started to have a whole host of problems. It began to jerk and hesitate at acceleration. …”

“I purchased about 4 months ago with about 139,000 miles on it. The vehicle now has 142,000 miles and is experiencing excessive oil consumption—approximately 0.9 quarts per 600 miles. VW seems to be pushing this off and as I try to use my extended warranty I purchased when I got the car, AUL has asked for an engine tear down. VW knows about this issue, as it is internally a known issue for this model, yet they are unwilling to help. At time of purchase, this issue was not disclosed to me, as such had it been, I would not have chosen this car.”

“So this is not related to a specific incident, more long term. The throttle response in this vehicle is downright dangerous. MAny of times I feel like I am going to cause an accident. The throttle response is so laggy and jerky that off the line it seems to hesitate for almost 2 seconds. Light turns yellow? Good luck, it will barely downshift and get moving before it turns red. Sometimes the response is good, sometimes it terrible. No predictability. Have to turn it to sport mode when I have to make a left turn into traffic just to get a jump start. …”

“PCV Failure causing the timing cover to leak oil and causing the oil pan to crack. This is a known issue with VW TSI engines. This PCV is a major issue not only causing the damage above but others are having to replace the rear main seal and crank case because of this. It's now in the shop for the next week and I'm out of a vehicle for the next week. This is not the only problem I've had with this vehicle. The last problem I had was the housing unit of the overhead lights, sunroof controls and sos when hanging down and broke out of nowhere. The plastic melted and cracked. …”
