NHTSA complaint #10748396, filed 2015-08, 91,305 miles“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. …”

NHTSA complaint #10108512, filed 2005-02, 32,500 miles“I took my 2001 Toyota Tundra to the mechanic because the exhaust system was getting noisy. When the mechanic had the car jacked up, he noted that the frame was extremely rusty on the driver's side in front of the back tire. It was actually almost rusted through. He said it looked like it could break at any minute and got away from the vehicle. I contacted the dealer where we purchased the truck who said I should drive it down for them to inspect it. I refused because of the safety issue nothing has been done at this point and the truck is still at the mechanics.”
