2015 Volkswagen Touareg

The Driver Assistance System (Adaptive Cruise Control, Front Collision Avoidance, AEB, and Lane Departure/Lane Keeping system) all do not work. The VW dealers have said the Front Collision Avoidance Camera is not working. The system was intermittently working, then stopped working on the interstate highway in the left lane. The car failed to warn/slow/break automatically while the ACC function was activated, forcing me to engage the brakes manually to avoid a collision. The ACC/Front Collision warning light goes on now but did not when it first malfunctioned, and still only goes on intermittently but the system does not work at all. I had two local VW dealers check out the Driver Assist system. One said the entire system is not working. Another said the fault codes are emanating from the Front Collision Avoidance Camera. This is VW part 7P6907217BZ1Y. I ordered the part in November 2023 from a OKC VW dealer online (since it was the best price.) They then told me the part was unavailable/on back order. However, it has been 7 months and there is no ETA on the part availability. The dealer sent me a text message exchange with VW and that is what VW told the dealer. I am concerned VW is no longer making the part as required by 49 U.S.C. 30118-30119 and/or 49 U.S.C. 30120. I am part of VW Touareg owner forums. There are other Touareg (and other VW model) owners who report this same problem, lack of part availability, and no info from VW on whether they are even trying to obtain/supply this part any longer. I believe this is a serious, widespread safety issue based on reading other complaints online by Touareg/VW owners who have ACC/Driver Assist, who face the same dilatory action by VW to perhaps avoid fixing this issue until their legal obligation to manufacture the part expires. The parts and overall ACC/Collision Avoidance systems are very pricey, and this is a direct safety issue. thank you
