Engine Noise Problems of Toyota Sequoia

While driving at 35 mph, the check engine light, vsc off light, and vsc trac light all came on at once, and the vehicle stopped accelerating, and I experienced a dramatic decrease in vehicle power. I drove the vehicle home noticing a drastic change in acceleration as the Sequoia would not accelerate normally; it would accelerate at a significantly reduced rate, topping out at 35mph on the flats and 16 mph on an incline, in addition, during start up, the engine makes a high-pitch vacuum noise, which drops off and normal engine sound returns. I have had the car diagnosed; error codes p2440, p441 and p444 are all present indicating a failure of the air injection pump. This is a known problem on Toyota Sequoias and tundras; however, Toyota has only acknowledged it on the 07-10 Sequoia by extending the warranty to 10 years and 150,000k miles for this part. It is clear from other posts on the NHTSA website and others that this problem also exists with the 2004-07 Sequoias as well. This is a safety issue that needs to be addressed before someone is injured, or worse yet killed.

While driving at 35 mph, the check engine light, vsc off light, vsc trac light, and the emergency brake light all came on at once, and the vehicle stopped accelerating, and I experienced a dramatic decrease in vehicle power. I drove the vehicle home noticing a drastic change in acceleration as the Sequoia would not accelerate normally; it would accelerate at a significantly reduced rate, topping out at 35mph on the flats, 30 mph on an incline, I was able to reach 70mph going down hill on a highway. Since that day, during start up, the engine makes a high-pitch vacuum noise, which drops off and normal engine sound returns. All dashboard lights are normal, until 10-15 seconds after start, when the vsc off/vsc trac/brake lights all illuminate, and remain on until the engine is turned off and the poor acceleration and decrease power are now the norm. This is a very dangerous safety issue should this happen to someone accelerating out of an intersection, or needing more power on a highway.

Piece of foam worth $. 10 dislodged from blower motor and was jammed in blower motor valve. This created a loud squeal sound. Had repair done at cost of $2000 last year 2014. Toyota dealer states same problem once again.

It made noise on start and while pulling out of parking the flames/smoke came under the engine/hood and whole vehicle got burned in few minutes. Recently had 30k service done by Toyota dealer. It has been running in excellent condition.
