Intake manifold failed water leaked internally into combustion chamber causing hydrolocking of engine. Upon researching causative actions I find that General Motors is aware of this defect and has redesigned the faulty parts but disavow any culpability even though a conscientious owner who properly maintains the vehicle cannot know what is transpiring inside a composite materials intake manifold, many have been known to burst into a fire and destroy the vehicles. One would tend to believe this to be a significant safety threat that should be addressed in a recall to replace this recognized failure of significant numbers, I that would warrant manufacturers replacement to provide safe transportation. By the grace of god I noted the vehicle acting up and returned home just as the engine quit and now is hydrolocking due to coolant filling combustion cylinders.
