2021 Volkswagen Tiguan Collision Avoidance Problems

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 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.

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.
