Engine Noise problems of the 2012 Volkswagen Jetta

With no prior indication, the engine glow plug light began flashing while driving on the highway. Within few minutes, the engine light came on and car started to loose power. Engine noise pitch changed, and was able to pull the car of the main freeway and barely made it to the dealership. As soon as we made it to the dealer parking lot, the engine cut off. Diagnostic of the car showed that the car suffered a catastrophic hpfp failure which caused debris contamination throughout the entire fuel system. 4 days later, the engine had its hpfp, fuel lines, injectors, and auxiliary pump replaced. Fuel tank was flushed and cleaned out from debris. Cost under warranty was $5500. The dealer said that they've had 50 cars exhibiting similar conditions. Cause of the failure is under investigation by vw. As owners, we have no clues what to do or when this will re-occur again which does not give me ant sense of confidence. I always fill at the same chevron station so it is not the quality of the diesel.

20k service had been performed on my car, again I notified vw that the noise is progressively getting worse and that I can no longer stand it. I also notified them of newer issues that have never happened before starting to happen, but they told me lets fix this issue first before moving on. This noise that had been happening for awhile now has now progressively gotten louder and now making noises when I am turning, something it had never done before. They did a check, and all of the sudden told me that my tires is the cause of the whole thing. They had told me my tires are cupped and feathered, which seem pretty odd considering when I purchased the vehicle the tire where brand new and pretty good (hankook). It did not make sense to me because if it was my tires and if they were doing proper multipurpose inspections they would have caught this when rotating my tires. It really seemed like they couldn't figure it out so they just advised me to buy some brand new tires, or try to call the manufacture about replacements, well I did that and hankook said feathered tires has nothing to do with tire but with the mechanics of the car. They had notified me that the only way tires get bad is if the mechanics of the car. The manger word for word told me this "there is a reasno why your car is so cheap, maybe you should buy $2,000. 00 tires, maybe the noise might go away", which infuriated me, because he is suppose to be the manager, but yet treats me with total disrespect and told me "we are done with this, we will not look into it anymore". This manager was rude and down right wrong to treat me like so (kearny messa vw, don't ever go there). I felt lost and scared knowing that they won't help me no more even though I still have my warranty.
