“The Toyota safety recall work done in 2012 to treated my vehicles frame to prevent rust perforation has failed. During nh state inspection areas where the frame had rusted through were identified. These areas had been treated under Toyota's guidance and at their expense. Due to frame rust perforation, and rust issues identified below my vehicle would not pass inspection. Toyota of portsmouth, where the initial recall work was initiated, and Toyota motor sales have both denied to remedy this situation. Many other 2001 Toyota Tundra owners were provided complete frame replacements. …”

“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. …”

“2001 Toyota Tundra 32,500 miles, both exhaust manifolds are cracked, the dealer states that the car is out of warr. After a month of back and forth with toy. Main office. They tell me they will pay labor and 1/2 part,I pay the rest ($350). This is a design problem exhaust manifolds don't crack, this problem is the fist line in the msn review of this car & all over the web. What does it take to get satisfaction & reliability from Toyota just admit there's a design problem and fix it..”

“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.”
