Consumer Description

At highway interstate travel speeds, vehicle was losing intermittent power. Exhaust at stopped, idle during trip smelled heavily of gasoline. White smoke blowing from exhaust with only 38k miles on the truck. Dealership is replacing the entire engine now and sounds like GM doesn’t want them to fully explore the cause of failure.
