Car was going 60-65 in carpool lane of freeway when my husband, driving, said he lost the ability to accelerate. This was without warning. We managed to cross 3 lanes and exit the freeway and he lost the ability to steer. The car broke down at the first stop light and began smoking very heavily. The car smoked for 30-40 minutes after the engine was already shut off. All I kept thinking was 'thank goodness we got off the freeway!' apparently, according to the mechanic which was later confirmed by bulletin no. 08-06-02-002b the fan shroud had been rubbing against the radiator causing it to crack and leak fluid. It overheated, melting and damaging many parts and causing us to break down on the freeway going 60+ miles an hour.
