Is the Toyota Tundra reliable?
Yes — the 5.7L V8 is very robust. The main early-build concern is the secondary air-injection system on 2007–2009 trucks.
What should I check first on a used Tundra?
Confirm the air-injection pump has been sorted on early trucks and check for cam-tower oil leaks.
Do Tundras have frame rust issues?
Earlier trucks had a frame-rust program; inspect the frame and check for any prior warranty frame work.
