Adaptive Cruise Control problems of the 2016 Volkswagen Touareg

Vehicle manufacture (volkswagon) has quit supplying/manufacturing a safety guidence parts for my auto. 7p6-907-217-bx-z1y collision avoidance camera not available I would like my anti self collision guidance repaired, but no parts for my 8-9 year old car. Part was on order (from 2024) and notified today not available and local car dealership order was cancelled. I might understand if I had hit a 10year threshold, but sure hurts now.

My lane assist camera is not functioning and Volkswagen is telling me the part is now obsolete and can't be repaired. It is part #7p6907217bxz1y. I took it to pompano Volkswagen on 4/4/24 and have been waiting for the part which has been out of stock and they (gunther Volkswagen since pompano closed) just told me on 8/8/25 the part is no longer available and offer no solution to fix this issue. Seems very odd that a car manufacture would be allowed to not supply a replacement part or be able to fix the problem for a car that is 8 years old. Especially for such an important feature like lane assist and collision avoidance systems - how am I supposed to sell a car without these features functioning? I have contact Volkswagen corporate customer care without any avail as well.

The windshield camera that is responsible for the imaging used for many of the system on the 2016 Touareg is a high failure item and has been constituently backordered from vw. When this camera fails, the advanced systems that were part of this option fail to operate. This includes adaptive cruise control, forward collision warning and automatic emergency braking and lane departure warning. The system does provide warning notifications, but they may occur at any time and there is no confidence the system is working. These notifications overtake other system displays making it difficult or even hazardous to navigate vehicle system menus at times. In addition, this vehicle does not offer standard cruise control, which can accelerate driver fatigue due to the loss of this basic and common feature. The original part on this vehicle is not available used in the USA, or from vw USA. There is a company in aus that repairs them, but in this particular instance, it appears the repaired unit has failed as well now. This system is very expensive to recalibrate, adding to the expense of the repair, especially without new parts available there is little route to be able to remedy this situation permanently for a safety device that is expected and was an added cost option on this model. Much of the diagnostic work has been performed by myself as I am a master automotive technician.

My acc/aeb went out over 2 years ago. At the time this vehicle was out of warranty. The dealer ordered the part (camera) and charged me for it. I waited over a year for the part. During this time vw lost a class action lawsuit regarding this and notified me that this was now going to be covered under warranty. I returned to the dealer to file the warranty claim. Warranty claim is now 6 months old and vw still has no news on getting parts and repairing this safety feature.

There was a big rain last week locally. I drove through a couple big puddles but nothing that's super uncommon for the area. Almost immediately, my car's electric components started going crazy. Acc stopped working completely. Lane assists aren't working. There was an error that I think was shift lock, but it was red, and the car was driving really weird.

Car has a design flaw. If car sits in the sun the emergency stop braking system will fail due to heat. The camera/computer board is mounted in the ceiling behind the rearview mirror. When the sun is out the system will fail do to heat. This problem is in volkswagons, Audi's and porche's with various models. The issue is described in detail in multiple blogs and car clubs. I bought the car used. I think this system is as important for safety as airbags. As a 2 stage safety feature to avoid an accident. This failure also affects the adaptable cruise control. Car color and climate affect this system. Volkswagon has an aeb recall but refuses to acknowledge the design flaw. Problem keeps occurring.
