2003 Toyota Tundra Problems

Exhaust & Emissions -- Verified

The V8 models can experience exhaust manifold failures. A leaking exhaust manifold will sound like an exhaust leak or an audible ticking noise from the engine compartment and will be especially pronounced when the engine is still cold.

Exhaust & Emissions -- Verified

One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.

Suspension & Steering -- Verified

Toyota issued a recall on the lower ball joint due to the possibility of premature wear from improper finishing in production. The ball joints will be replaced under the recall. There are two separate recalls combined here, one applies to 2002-2004 and the second to 2004-2006 Models.  Please contact you local Toyota dealer to see if your vehicle is included.

2003 Toyota Tundra Recalls (Recent)

Body, Interior & Misc., April 11, 2013

RepairPal Expert Overview:

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator module found.

2003 Toyota Tundra Reviews

Hello my 2003 toyota tundra's motor cap has a little bit of withe stain i dont know if that is normal?

I am the original owner of this 03 Tundra Limited 4 Wheel drive and at 305,000 miles it has been truly an awesome truck. Two timing belts and I always change the water pump when I have the timing belt replaced. The shifter broke back in Sept. or Oct. of 2012. I read that some of the Tundra's had that problem. I called Toyota and they were nice enough to pay for the parts to help me. They probably would have paid for the entire repair, but since the mileage was so high something is better than nothing. I can't wait until the 2014 come out, I am tempted to replace the 03 with the 14. Thx TOYOTA... A Loyal Customer..
