“1994 Pontiac Bonneville. Due to corrosion the engine cradle bolts / mounting failed and engine fell out of car. Luckily it was while turning around in the driveway, if it had happened on / at road speeds there could easily have been loss of steering control, multi car involvement, injuries, or loss of life. Gm service offered zero help on recall or service bulletin information and denied any responsibility for defect or repair.”
