2005 Toyota Sequoia Engine cooling Problems

“Vehicle emits a rotten egg smell through the ventilation system whenever we step on the accelerator. Sometimes the smell is so bad that it burns our eyes and nose! Toyota acknowledged the problem, stating they could not do anything until a recall for the catalytic converter is issued. They further said that earlier year models (2003-2005) vehicles had the same problem!”

“Our vsc/trac light and engine light simultaneously come on for an unknown reason. Our mechanic can not find a solution. Our emergency brake light comes on and off for no necessary reason as well. This has happened three or four times and no one can fix it. I am afraid to take it to Toyota because of the bad experiences posted online where consumers have received many varying answers, expensive repairs, and in some case, still no solution. We are in the market to buy a new car and it makes resale very difficult with these lights on and no answer as to why they are on... …”

“I had owned a 2001 Toyota Sequoia for four years before recently trading it in for a 2005 model. I obviously love the car but there is an unfortunate flaw in the 2005 model that differs from my 2001 model. When the vehicle is started cold the idle speed is very high - about 1500+ RPM. The idle doesn't slow down appreciably until the car has warmed up - about 5 minutes depending on the weather. The problem with the high idle comes when trying to drive the car on an icy surface. …”

“Check engine light and vsc/traction control lights keep coming on. Took it to Toyota of lewisville, texas on 30 june 06 and again to Toyota of killeen, texas on 15 july 06. Toyota of lewisville told me it was bad gas and that the problem was fixed. On 13 june 06 the light came on but went off after a couple of miles. On my way to dallas on 14 jun 06 the same thing happened. Later that day on my way back from dallas the lights came back on and I took my Sequoia to Toyota of killeen on 15 july 06. They worked on my Sequoia until 25 july 06. …”

“Engine noise is very loud. It would seem that the sound insulation around the engine is missing, but it is not. The radiator fan is especially loud on initial acceleration. My first 5000 mile service was just completed and after my complaint, the dealer performed a recall on the fan which was supposed to reduce the noise. It is no better. During hot summer days, it is worse because the fan runs faster (or louder) to maintain proper engine temperature. (note: I traded in my 2002 Sequoia with 80,000 miles and never heard the engine on that car).”
