2008 Toyota Sequoia SUV SR5 4dr SUV (5.7L 8cyl 6A)
Engine failure at 138k miles
 I bought brand new. Always kept up with oil changes.  Mostly highway miles.  A valve spring broke, hit the cylinder head which broke and destroyed the engine block and everything.  For the dealership to build me a new engine is $15k in parts, not including labor. You can't buy new engines like ford and GM.  I bought a used engine for $6k and the labor cost ended up in a bill for $9850.  The new engine is not working properly but the dealership is working with me.  I am disappointed.  I wanted to keep this truck forever.  Now I'm faced with a tough decision.  I also lost 3mpg's.  Now around 13.4 mpg's when I used to average 16.4.
