I took my H2 into the dealership to initally look at a RECALL issue relating to the following: http://www.tc.gc.ca/roadsafety/recalls/recall_e.asp?RECNO=10218&make=&Model=&year=&cmd=prev (From Transport Canada) This is a link form NHTSA in the USA, http://www-odi.nhtsa.dot.gov/cars/problems/recalls/results.cfmhttp://www-odi.nhtsa.dot.gov/cars/problems/recalls/results.cfm
Dealership stated that this problem does not relate to my VIN#, but I asked them to have a look at the brakes due to the fact that I felt there was something wrong with them. They phoned a short while later and I was told that my Power brake Hydro-Boost system was failing (GMPart#15212823-Price $750.00CDN) or (CARDONE Part# 527359-Price $158.00US), after some thought about timing and need for the vehicle I decided to let them go ahead and replace the unit, so far $1,500.00 for parts and labor.

I phoned back to see how things were going and to see when my truck would be ready and thats when the informed me that the calipers were not releasing when brake pressure was applied...F**K!! They informed me that I now need a "Brake Pressure Modulator Valve" cost: $1,450.00 just for the part!! GM Part number is either 88936321(Old SKU #) or 19121235 (New SKU#). I asked WTF?? How could this be?? They replied my brake fluid was contaminated with something...this is a big problem now...the only people who mechanically touch that truck is the dealership...they just finished doing a full warranty & brake check at my big 50...now my brake system is fryed...a sample of the fluid is being sent out for analysis in order to find out what this contaminate could be...my nightmare is now I may have to replace my entire brake system which could run up to $10,000.00 +. Did anyone have this occur to them at all that could shed some light on my plight?? Or at least point me as to where I can save some cash before going down this slippery slope! Is there someone at GM or Hummer I could call?

Hooped...
