In owners' own words
When on a long highway trip on the weekend of june 7, 2008, my husband noticed black spots on the rear window of our 2001 Toyota 4RUNNER (121,000 miles).
The rear differential on my Toyota 4RUNNER rusted so badly in 9 years of ownership that the structural steel frame that supports the differential gears (The housing) cracked and oil spilled out on the road.
Since I got the car, the ignition key does not get in properly and sometimes does not start the car. The movement of the wheel helps sometimes.

On certain sport utility vehicles, due to a manufacturing issue in the front suspension lower ball joint, there is a possibility that the surface of the ball of the joint may have been scratched. The ball joint may eventually experience excessive wear and looseness, resulting in increased steering effort. The lower ball joint may separate from the knuckle causing loss of steering control and a crash could occur.
