2001 Toyota Tundra limited V8 4X4, currently at 39,400 miles. At approximately 33,000 miles - 2 years ago - I took the truck into the dealership for a loud knocking at cold start-up. They were "unable" to reproduce the problem even after leaving the vehicle for two days. The next visit for service, I had cracked exhaust manifolds, but was told I was out of warranty and it would be about $1700 per manifold to replace these. I purchased quality aftermarket manifolds and had them installed by an independent shop for less than $1,200 for both sides. I now see where many, many others have had this same experience and believe the original manifolds to be faulty. Toyota needs to either make the repairs under warranty, or reimburse those of us who paid out of pocket for replacing defective, poorly made manifolds.

Vehicle stalls at any speed and when going up a hill. The check engine light had come on. There were times when the engine felt as if it were dragging and would be able to be restarted but when put into gear, the engine would die. The transmission was found defective and was replaced with a Toyota remanufactured transmission. Also the engine light illuminated, it was determined the oxygen sensor needed to be replaced. The air condition did cool properly.
