Adaptive Cruise Control Problems of Volkswagen Tiguan - part 2

My vw Tiguan was out of alignment, as happens to every car. Unfortunately, the vw dealership informed me that I cannot get a simple alignment for $100 because vw requires calibration of the adaptive cruise control any time an alignment is done. I could not find this anywhere in the owner's manual, nor are there any other warnings on the car or in any paperwork I signed. The vw dealership wanted an additional $400. 00 (for a total exceeding $500) to provide both services. I am concerned about this 1) because vw does not communicate that this is a limitation of the acc system, and 2) while an alignment should be the customer's responsibility to pay for, calibrating the acc system should not. Anyone could go get an alignment done at a tire or brake shop for about $100 - what happens if they try to use their acc afterwards and an accident happens? vw should cover acc calibration as part of the limited warranty, and clearly warn customers not to perform one service without the other.

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.

My adjusting distance / gap configuration is set to "far" but it so far it happened twice while @70 mph speed and the car ahead of me start slowing down and my car was supposed to start adapting, instead it start accelerating which isn't the norm. If I wasn't paying attention I could have rear ended the car in front of me on high speed causing death or major injuries to everyone around me.

When using remote start function the following safety function are not operative, not working as advertised by vw, adaptive cruise control, cruise control, automatic/emergency braking, rear cross traffic warning and forward collision warning. I have been trying to get my local vw dealer, vw of corpus christi to repair the issue and the are telling me that it is a "known issue and that vw is working on a fix. This has been the case for over two months now. My concern is that vw is selling vehicles that have a potentially dangerous safety issue and are using they costumers as test dummies. If vw is in fact aware that there vehicles have safety issue, why are they still being allowed to sell them in the us? seriously concerned. . .

When the vehicle is started remotely and cruise control was not turned off before turning off the vehicle, the acc system shows an error and fails to engage when the driver tries to set cruise control. If one relies on acc often but does not often use remote start, this situation can lead to improper driver expectations and rear-end collisions as the car doesn’t brake when the driver expects it to. This is a well-known issue at vw dealerships and widely reported by owners on vw forums. Mostly it’s just an annoyance, but today I experienced it as a safety issue.
