"went for an oil change. Was told that the exhaust manifold is cracked and needs to be replaced ($850) for that particular repair. Was also told that there was barely any oil left in the engine - no engine light or low oil light came on - researched and found out the the 4 cylinder Ecotec engines is a known issue and the class action law suit has finished in Canada."
