My 2000–2006 Toyota Tundra frame is rusting through. Will Toyota still fix it?

Short answer: First-generation Tundras from rust-belt states are known for frames rusting through. For 2000–2003 trucks, Toyota's recall 09V444 covered rear cross member corrosion, and a separate Toyota frame replacement campaign expired in 2012. 2004–2006 trucks got a corrosion coating campaign. Most of that help has ended, so check your VIN, check the dealer history, and inspect the frame closely before you trust the truck with a load.

Symptom: Heavy scale or flakes on the frame, holes you can push a screwdriver into, rust at the rear cross member under the spare tire, or brake lines rusting through.

What to check first

1. Run your VIN at toyota.com/recall and register it on Toyota's owner site, which shows past dealer work, including coatings or frame swaps.
2. Inspect the frame behind the front wheels, around the rear cross member and spare tire, and anywhere scale is heavy. Tap and poke suspect spots.
3. Remove the spare tire from under the truck if the cross member is rotten. Toyota told owners to do this under the recall.
4. Check the brake lines. Owners found lines rusting through along with the frame.

Likely causes

1. Inadequate rust protection on the frame. Toyota recalled 2000–2003 Tundras in cold-weather states because the rear cross member could corrode and let the spare tire or brake lines fail.
2. Road salt over many years. Owners note frames from rust-belt states are the ones that rot.

What it usually costs

Help from Toyota is mostly over: owners say the frame replacement campaign for 2000–2003 trucks expired in 2012, and the 2004–2006 coating campaign is done. Owners didn't post repair prices in these threads. Get a frame shop to look at it and quote it if the rot is localized.

Is it safe to keep driving?

No, not if the frame has holes in key areas. A rotted frame or cross member can fail under load and brake lines can burst. Have it inspected by a frame or alignment shop. Verify with a mechanic.

DIY or shop?

Inspection and cleaning are DIY. Frame section repairs need welding and are a shop job for most owners.

Recalls, bulletins and complaints in plain words

• Recall 09V444 (2000–2003 Tundra sold or registered in 20 cold-weather states and DC): excessive corrosion of the rear cross member could let the spare tire fall or affect the brake lines. Dealers inspect and replace the cross member and related parts, including brake lines, as needed, or apply a corrosion protection compound. Owners were told to remove the spare tire until repaired. If your truck is part of this recall and it's still open, the dealer fixes it for free.
• Limited service campaigns (Toyota programs, not recalls): owners say the 2000–2003 frame replacement campaign expired in 2012, and 2004–2006 trucks received a corrosion-resistant coating campaign that shows up as D0D in Toyota's records.
• NHTSA complaints: 1,776 keyword-matched complaints for Toyota Tundra 2000–2006 (of 3,757 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-18; keywords: frame, rust, corros, rotted, rotting, rotten).

What owners report

• In Early 1st gen (2000-2003) Tundra frame replacement FAQ on Tundras.com, an owner explained who might still qualify and that the limited service campaign expired in 2012. A 2003 owner whose frame was coated in 2011 now had holes, and the dealer said the program had expired. Another owner noted there was never a specific frame recall, only the rear cross member recall 09V444.
• In Recall Frame Coating Questions, a 2006 owner asked whether a Toyota-coated frame on a used truck was a good sign. A long-time member said the coating can let rust work from the inside out, and that a frame rusty enough to get coated is probably bad by now.

My take

My advice as a former pre-purchase inspector: on a first-gen Tundra, I get on my back with a flashlight and a screwdriver before I even ask the price. A clean-running engine doesn't matter if the frame is soft.

Vehicle focus: 2000–2006 Toyota Tundra (first generation), especially trucks from salt-belt states.

Safety / mechanic note

A rusted-through frame or brake line can fail suddenly. Verify with a mechanic.
