2003 H2 Hummer, transmission fluid leaking into the coolant system that requires removal of all hoses and radiator flushing and cleaning and possibly removing the transmission because of contamination. Extremely expensive and I believe to be a defect in workmanship.

Consumer was going 70 mph and the two front tires locked, while the two back tires kept moving. Vehicle then continued to skip. The driveshaft was replaced. For the past 8 month this vehicle has been in the shop more than at the consumer's home. The vehicle has needed a new alternator, transmission, battery, ignition and drive shaft. The roof leaked and the consumer had to replace one of the side windows.
