2021 VOLKSWAGEN TIGUAN Forward Collision Avoidance Problems

Vehicle keeps having all warning lights and warning messages come on whenever the car starts. Warning lights maintain on constantly and has audible beeping to indicate the warnings. Vehicle would also put itself into park randomly at, as well as disengage collision and lane sensors while driving. Vehicle has been taken to the dealership, and has been reproduced by them, stating "we have never seen this before and are not sure what to do, we need to reach out to Volkswagen directly" most recent update, they needed to replace the door harness and F5 module but are still unclear with the status of the repair. Dealership has indicated it's safe to drive if I wanted to pick it up while they figure out the issue.

I have had to replace multiple windshields for something barely hitting it on the freeway - I think this is my 4th windshield and have not been driving near big trucks or construction during the incidents. Another issue is that I have had the car abruptly break in both leaving the parking lot and on the freeway in traffic thinking I am going to hit something when nothing is there which seems to be a sensor issue.

When using the remote start the ACC and automatic braking system will fail and give an error. This is a known issue for VW and they have not provided a solutions in over 2 years. To make it work again you need to either turn the car off and back on without remote start or disable the ACC before using the remote start.

From a cold start and backing down the driveway, the SUV displayed an error code “Error: Driver Door Contact Switch” and automatically put the park break on. The driver had to put the Tiguan in park, turn off the vehicle, and release the emergency break restart the Tiguan and pulled back up the driveway. The driver proceeded to open/shut all the doors to ensure that all doors were closed. The drive started the Tiguan and proceeded to back out the driveway and the same thing happened with the error code and the park brake. The driver restarted the Tiguan and pulled back up the driveway and turned off the Tiguan exited the vehicle locked it and noticed the error code was still showing on the dash.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving approximately 15 MPH, the vehicle would brake independently suddenly. The contact stated that the independent braking had been an ongoing failure since he purchased the vehicle. The contact stated no warning light was illuminated, however, prior to the sudden braking, a warning beeping sound would activate. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that there was no failure of the braking system. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 11,000.

Mileage: 11,000

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.

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...

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 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.
