No way a timing chain should go bad at 55000 miles. The belts are either bad or too small for the job. Either way this a built in defect and by law should be covered for the life of the vehicle. If I repair this will I have to do it again in 55000?

Sounds like they are all alike. When accelerating engine light comes on. Loses power, shakes and rattles!

Update from Nov 7, 2016: Replaced coil and all plugs.

This problem occurred 1 time when I first bought truck, now it reoccurred 4 times in the last week. when i called the service department, they said they had not heard of this problem. After going on line I see it is wide spread.

Check engine light came on today as I passed a truck, I read the code and it say misfire No 2 cylinder.

I will be going to the dealers in the morning.

Update from Jun 22, 2013: The dealers Replaced the coil and the plug on No2 cylinder
