2021 Volkswagen Tiguan

Like many others, at 55k miles, our oil separator malfunctioned causing our oil pan to crack and dump every drop of oil. We had to replace the oil pan and fortunately our mechanic friend figured out it was the new pcv valve malfunction causing too much pressure in the engine. My wife was luckily pulling onto our property when the car essentially shut itself off. When searching for the valve I needed, talking to multiple parts dealers and then a vw tech, none of them are sure why there’s no recall. It happens between 50-60k to THOUSANDS of people now. Then I watched videos on the issue and the mechanics online are all saying the same thing- this should’ve been a recall 2 years ago and are all asking the same question. It’s time VW does what’s right. It’s awfully coincidental that they installed plastic oil pans that would crack and leak under instead pressure, rather than a blowout seals because of the valve failure.

While driving, using cruise control set to 75mph, I braked to slow down. That worked cruise control disengaged fine. I changed to the adjacent lane that was wide open and pushed the resume button on the steering wheel. I noticed I was passing several vehicles on both sides of me. Looked at the speedometer reading = 98 mph and felt further acceleration. Put my foot on the brake to disengage cruise control and slow down. I checked the cruise control setting on the dashscreen. It still read 75 mph. When the speed of the vehicle returned to 75mph, I again "SET" the speed of cruise control at 75mph, and all was normal again.

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. There are numerous forums that have talked about the issue. I have even brought it up to the dealership with no fix recommended. I have driven so many cars in my day, not one like this. Thinking about selling the car back just to get something safer unless they come out with a fix for it.

So this issue occurs once you remote start your vehicle. If you have remote started your vehicle, you get in the car, activate it by pressing the start/engine on button and go - when you later go to use the Adaptive Cruise Control or Standard Cruise control the vehicle will fail to activate either cruise control option. The only way to regain control of this feature is to power off the car completely and then restart it without using Remote Start. This is a known VW issue and there has been no observable action or report about this issue except for discussion with the dealer/service department. It should be noted that this is a non-issue if you do not use the Remote Start Function.

The adaptive cruise control will be working perfectly fine and then it will just stop working. I can be using it all day and then all of a sudden I get in the car and I get up to speed and I go to press the adaptive cruise control button to set it and it starts off trying to set the speed and then all the sudden I get an error saying that it can’t set the speed. However, none of the buttons to try to set it back on track will not do anything you just keep getting the same error code with the little red light on the dashboard with the car in a little parentheses things around it. But if I were to put it in park turn the engine off and then turn it back on it works perfectly fine. It’s been dangerous because that’s happened to me on the interstate and I’ve noticed that it happens quite often when I’m on the interstate so I’m not sure if it’s because of the speed of up to 75 mph that I’m going but it’s also done that when I’ve been going 30 mph and I’ve tried to set it. It’s dangerous because if I have my music up loud I don’t hear the ding and the light on the dashboard doesn’t always catch my attention so I’m assuming that the adaptive cruise control has taken and is working correctly when it’s not. I bought this vehicle brand new on a lease with 100 miles on it and it’s always done it since I purchased the vehicle in September 2021.
