general problems of the 2009 Volkswagen Touareg

Om April 11, 2015, I was returning from a day at the mall with my mother and children in the car. I entered a 35 mile per hour zone and reduced my speed accordingly. My car started making a loud rumbling sound that was coming from under the car. We first thought a tire had blown out. We pulled over, got out and checked the car and all of the tires were fine. We pulled back on to the road and didn't hear the sound again until my speed reached 25 miles per hour, then the loud rumbling started again. I was almost at my mom's house so we made it to the house and I called a tow truck to tow the car to my mechanic. My mechanic contacted me on Monday morning 4/13/15 and let me know that something exploded in the driveshaft of the car and the whole driveshaft assembly needed to be replaced. He indicated it was unusual for this type of problem to happen on a vehicle with 87,766 miles on it. He also indicated that he found it strange that when he contacted the local Volkswagen dealer, they actually had a driveshaft in stock. He indicated that this type of part was not a common repair and would usually be a part that would need to be ordered. The vehicle cost $1400. 00 to repair. I took pictures of the defective driveshaft which show where the piece exploded from the driveshaft. I have access to a company car for my daily work and my office is located 5 miles from my house. I drive my personal car very little and keep it in top shape. I did research online after this incident and found that there are other accounts of people talking about their driveshafts for their Touaregs going bad around 80,000 miles. I am reporting this in hopes there is a trend that can be looked into. This was a dangerous car issue and I purchased the Touareg because I wanted a safe SUV to transport my daughters in. Now I am nervous about the overall safety of this vehicle.

My 2009 vw Touareg tdi experienced a failure of the reductant pump for the diesel emission fluid system (def. ) researching failure rates of this system has shown a very high failures of this system in the vw Touareg and passat clean diesel application for model year 2009 and newer. Proposed solution to reduce crystallization and clogging of system has resulted in 3 service revisions, with the most recent calling for removal and replacement of the entire system (tank, pump, line and injector) at a cost of $1,5000. Vw will not cover any costs or issue a recall. This same system and parts are used in the Ford f350 and Chevrolet duramax clean diesel applications with similarly high failure rates to the best of my knowledge all light duty clean diesel manufacturers are experiencing a failure of this system with no recall or coverage against future failure. It is apparent that the supplier of the def system used in common light duty vehicles manufactured faulty parts on multiple vehicles. The manufacturers of these vehicles have records of the failure rates and can demonstrate that the system has been faulty, which results in non compliance of federal emissions standards. What steps can be taken to investigate this and provide a long term solution?.
