Gradual coolant loss over time with no evidence of leak found. Took it to the dealer and they said that the head was porous. My extended insurance is not honoring the claim because gm has a bulletin #06-06-01-019b. The cylinder head assembly has a defected casting manufactured by castech. Why no recall?.

Engine losing coolant, with no apparent signs of leakage. Coolant appears to be leaking into the engine oil, causing it to sludge, thereby causing engine failure. Gm is aware of an issue and issued TSB 06-06-01-019b for defective cylinder head casting. I bought this car used last year and now owe 10000 for a car that needs a 6000 engine replacement. Gm should be made accountable for this since they are well aware of the issue, per their own directive.

Vehicle was shipped with heads that would crack over time. The car has been leaking coolant for over a year and caused major engine failure. This is happening to many hundreds of thousand vehicles and should be a recall/compensation from gm.
