2021 Volkswagen Tiguan Driver assistance Problems

My name is [XXX], and I am writing today to express my complete frustration mentally and financially with a CPO 2021 Volkswagen Tiguan (VIN [XXX]) I purchased XXX. To date my vehicle has been in for service multiple times – countless times for an issue with the infotainment system and driver warning indicators that is still unresolved and again for months waiting on a new engine due to an oil consumption issue that was finally resolved November of 2025 (Case XXX). My recent service visit on XXX was due to a “12 v battery not charging” error message. The vehicle was immediately taken to VW of [XXX] where we were advised it would be 3 weeks before my vehicle would even be looked at (which is atrocious) and not to drive it because further damage would be caused with no alternative solution offered for transportation. I then had the vehicle towed to a repair shop where I was advised the alternator “fried a 400-amp fuse and killed the battery, which should not happen, especially on a vehicle that has less than 50,000 miles on the odometer.” I paid $1,605.37 for a new alternator, 400-amp fuse and battery. Completely appalling and disappointing considering I take excellent care of my vehicle and it is supposedly an inspected, certified pre-owned vehicle – that’s a lemon in my opinion! I am seeking reimbursement for this huge expense for a vehicle that should not have these issues! I look forward to a resolve to this urgent complaint. Regards, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

The backup camera freezes and stops working. The car has to be turned off and back on again for it to work. The dealer informed me it was not a safety issue and I should use my mirrors. This is absolutely a safety issue.

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.
