A software update from Volkswagen causes the infotainment system to crash and become unusable and no longer functions. Car owner is forced to purchase a new infotainment control system which is back ordered nationally with no estimation of arrival. The back up camera, and rear traffic warning no longer works as the screen is black. There is no radio, safety controls, vehicle notifications, no media control or connectivity to phones.

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)

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.

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.
