Brake Disc Caliper problems of the 2009 Volkswagen Routan

The contact owns a 2009 Volkswagen Routan. The contact stated that the front rotors had to be replaced three times since the vehicle was purchased and twice in the last year. The vehicle was taken to the dealer. The technician replaced the rotor, caliper, and hub. The technician insisted that the failure was normal wear and tear. The vehicle was not properly repaired. The failure mileage was 65,000.

Randomly stalls while driving- brought to mechanic, paid almost $1000 to try to get fixed, brought back when everything paid for didn't fix & was told to report ignition switch recall to vw to get fixed. Also lost power to rear dvd within days after purchase & never knew what to do. Brake pads are bad within 3-4,000 miles- windshield washer squirter unrepairable. Biggest issue is the ignition switch though, if that what is causing van to stall - while going steady speed, usually occurs over 25 mph for more than 5 miles- van starts jerking like it's going to stall & when sitting at a stop light or sign, or parked, idling, stalls & takes multiple attempts to restart - this has been happening since I purchased my 2009 Routan in 2014 when it had less than 60k miles. I have brought to mechanics that are friends & to multiple dealerships & shops to diagnose & fix & paid for everything out of pocket to get fixed or replaced & it has never fixed the problem for more than a week. For the brakes, I buy only the mid level or high level grade brakes & have had to switch both front & rear brakes, rotors & calipers out @ least 3-4 times per year since about 1 month after ownership. Every time, 1-2 brake pads were completely bad & gone while the others were about 50-70% . Another issue, that has never been able to get fixed is the a/c- after recharging, the a/c will blow cold on the drivers side front only & hot throughout the rest of the car. When heat is on, same problem, only blows heat in front & cool in back. How do I get all recalls for my minivan repaired through Volkswagen? how does the process work? I have 5 small children & this is our only form of transportation. Will I be provided with a loaner that will seat my entire family while my vehicle is being repaired? please advise as I have had this minivan for over 3 years with these issues and spent thousands of dollars.

While driving in phoenix az the van began to shake and steering became difficult. (this has happened in the past multiple times intermittently). Later the same evening brakes began to squeak and grind. Until this day the only issue had been the intermittent shaking while braking. There was no squeaking prior to the grinding. Right rear caliper was replaced along with all front/rear brakes rotors drums and hardware. Cost=$780. 55.

Premature rear brake failure. With 40k miles the rear caliper locked causing burining of the pads, and requring complete replacement of all rear brake components.
