2006 Toyota Sequoia Owner Comments

problem #16

Nov 062015


  • 147,625 miles


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 Tundra; 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 low speeds the vehicle experienced a momentary loss of power and a grinding/vibrating of the brakes while in motion. The trac off and vsc trac warning lights came on along with the brake light. The warning lights and vibrating of the brakes could only be reset by turning the ignition off and restarting the vehicle. It happened twice in the last 12 hours.

ABS, trac, vsc and brake and check engine lights all signaled fault codes. Codes are #1251 and #1223, again, this after computer module was replaced at full cost to the consumer $1,059. The same fault has re-occurred in less than 6 (six) months of having replaced the ABS, trac, vsc computer module.

After putting gas in the vehicle, I pulled away from the gas station and when I came to a stop sign before entering the main thoroughfare the brake pedal was so hard to depress that I almost had to stand on it to get the vehicle to stop, and nearly was unable to before plowing into oncoming traffic I also noticed that the "trac off", "vsc trac", and brake malfunction indicator were all illuminated. It was a real panic situation because it was totally unexpected and my wife and 2 young daughters were in the vehicle with me. I am an 20 year + ase master automotive technician with over 30 years experience. I stopped the vehicle and visually checked the brake system as well as I could on the side of the road and saw no obvious cause for the issue. The only way I could get the warning lights off and the brakes to work was to turn off and restart the ignition. After that, the vehicle went the rest of the day (140 miles) with no problem. I am now afraid to let my wife and kids drive this vehicle until I figure out what's wrong with it. I do see where there are a few similar complaints, and a couple that are pretty much identical to mine. This vehicle is in excellent condition with only 52,000+ miles on it. This is a serious safety concern and it's only a matter of time before someone is seriously hurt of killed due to this issue. There should definitely be some kind of safety recall issued.

I have a 2006 Toyota Sequoia. The vsc & trac lights as well as the brake light and the tire pressure light started coming on in the morning, usually when cold. Not sure exactly when this started but it has been happening for years now. The lights usually go off when the engine is shut off and usually the only time it is an issue is when the weather gets the slightest bit cool. After researching this issue online, I am seeing that this appears to be a very common problem and apparently there have been some brake related issues (vehicle not braking properly) also associated with these lights, although there has not been a recall to date.

On two different occasions, while pulling into traffic from a stop, at less than 10 mph, the car lost power, the gas pedal was non-responsive, and the car seemed to brake for a few seconds resulting in my temporary loss of control of the vehicle. The vsc light on the dashboard flashed several times. After a few seconds, power to the vehicle returned.

2006 Toyota Sequoia has experienced intermittent electrical problems since purchase. On 30 July 09 vehicle experienced multiple computer failure of ECU, vsc, and other computers. Toyota tech reps say vehicle could not have caused problem, therefore it must be an "external' fault. However, there is absolutely no evidence of any external arcing or other power surge indicative of an "external" event. Toyota refuses to admit potential of a latent defect and says incident must be referred for insurance. Toyota will not address logical questions as to why other (non-protected systems such as the radio) in the vehicle still function in light of the alleged "external event." Additionally, there were no circuit breaker or fuses blown, so again how is it possible for the "external event" theory to be valid" given the anecdotal evidence on the web concerning Sequoia ecus and vsc computers, what action can NHTSA take to have the manufacturer address the problems"

When the vehicle has stopped, it can surge forward a bit. Feels like the vehicle behind me has rear ended me. The force of this seems to vary a bit.
