Toyota Tundra (2014–2021) Problems to Check Before You Bid

The 2014–2021 Toyota Tundra (the refreshed second generation) is a tough truck with a strong resale value. Its 5.7-liter V8 has a reputation for lasting a very long time. That's why salvage Tundras sell for strong money. But the trucks have a few known problems that can turn a deal into a headache.

011. Secondary air injection pump (5.7L)

This is the best-known Tundra issue. The secondary air injection system pumps air into the exhaust on cold starts to help clean up emissions. The electric pump sits under the truck where it gets road spray, and moisture can corrode it.

• Signs: a check engine light with secondary air codes, rough running on cold starts, and in some cases reduced power (limp mode).
• Why it matters: the pump and valves aren't cheap, and a truck in limp mode isn't fun to drive home.
• Check: ask for any codes if the listing allows, and look at service records after purchase. Many owners have had it replaced.

022. Cam tower oil leak

Some 5.7L engines develop an oil leak at the cam towers at the back of the cylinder heads.

• Signs: oil seeping at the back of the engine, burning oil smell.
• Why it matters: the fix is labor-heavy because of where it is.

033. Frame rust

Tundras sold in salt-belt states can show frame rust. The worst frame problems were on earlier Tundras, but northern trucks of every generation deserve a close look underneath.

• Look at: the frame rails, crossmembers, spring hangers, and brake and fuel lines.
• Assume the worst on a northern truck if you can't see underneath.

044. Transmission and torque converter shudder

Some owners report a shudder at light throttle. It's usually not a major failure but listen for it on the test drive after you buy.

055. Front-end hits

As with any truck, front-end damage can mean radiator, condenser, headlights, grille, bumper and airbags. Check for frame horn damage. See how to judge an auction vehicle you can't drive.

06The good news

The core 5.7 V8 and the transmission are generally strong. Most Tundra problems are bolt-on systems around the engine, not the engine itself.

07How to bid it

Know the fixed value (cab, bed, 4x4, trim, mileage), subtract visible damage, add a reserve for the air injection system and a frame reserve on salt-belt trucks, then fees and transport. Compare it with the Silverado, F-150 and Ram guides.

A clean-framed Tundra with a healthy 5.7 is one of the safest truck flips at auction.
