In what may be old news for some people, there is growing evidence that Toyota Tundra bumpers may be rusting much faster than they should be. While exact numbers are hard to guess, it’s safe to say this problem affects a very small percentage of Tundra owners. Based on our correspondence and the handful of forum threads we could find, this problem is mostly confined to areas of the country where rust is already an issue.
Here are some pictures of the typical types of rust being described - the first was sent to us, but the rest were found searching TundraTalk.net and TundraSolutions.com. It’s fairly minor rust, but totally unacceptable for such a new vehicle.
