You are what drives us

We create vehicles by listening and responding to you. Why? Because it’s our belief that our cars should do more than help you go places on the road; they should also help you go places in life.

We currently offer more low and zero emissions vehicles combined than any other automaker to give customers the most choices to reduce their carbon footprint. Toyota is also cultivating respect for our planet by directing our efforts to three other sustainability focus areas: water, materials, and biodiversity because there’s more than one way to drive change.

Helping make safe roadways

Safety may begin with the driver, but it certainly doesn't end there. We're constantly innovating and researching ways to help prevent accidents, as well as helping protect those inside and outside of our vehicles in the event of one. Then we share our research and data with a variety of universities, government institutions and more, to help make the roads safe for everyone.

    Extended Breather for 2005 Sequoia
    5 Stars
    Extended Breather for 2005 Sequoia
    My rear differential of our 2005 Toyota Sequoia slowly filled up with water as we would put our boat in the lake. The old breather got full of dirt and grime (like they usually do) and wouldn't seal to protect the differential from water intrusion.I used this union/nipple, some fuel hose and a remote breather to move our breather up behind the gas filler. I did have to remove the wheel well splash guards, but it was less than a 2-hour job.I also needed these parts and a couple stainless steel hose clamps from the local hardware store:1. Raider Polyurethane Fuel Gas Line Tubing Hose Roll Blue (5 Ft. x 5/16 In.)2. Dorman 924-284 Front Axle Vent for Select Lexus / Toyota ModelsWe'd have to seriously dunk the Sequoia now to have any water intrusion.
