Purchased a used 2004 Nissan titan truck with lower miles. Rear axel exploded and burst into flames when driving down the freeway. (Bowling Green, Kentucky) We managed to pull off to the side of the freeway without hitting anyone. Fire dept was able to put the flames out. Didn't find any recalls about the Truck when we bought it. Now I have seen reports on line that this has happened to other consumers. Something needs to be done to warn consumers. We could have died. We could of hit others and killed them as well. Dealership has completed repairs and seen the defect. We have the damaged part. There were no prior warnings. Vehicle was inspected before the road trip to insure it was safe.
