general problems of the 2005 Toyota Sequoia - part 1

After several years of fighting problems with, after braking to a brief stop, the loss of power/abs grinding when accelerating and turning right, now the abs is completely dysfunctional. Both trc lights will turn on and usually the parking brake, and when braking at speeds less than 10mph the abs will activate and prevent bring the truck to a stop without pumping them, on dry pavement. When the abs light turns on, then braking is possible, but all pressure is gone from brake booster and brakes sound like they're grinding, not like the sound of abs engaging. Very dangerous to drive in snow as front brakes work but drive axle doesn't disengage when the brake pedal is depressed. Regular mechanic won't engage with diagnosing issues as he feels the problem is partly computer malfunction and Toyota won't allow for used part mismatching. Abs/ecu is failed.

Malfunction indicator lights - check engine, vsc off and trac off. The vehicle goes into limp mode. The issue is both a mechanical and engineering defect causing the override of the entire aip system. Parts affected are air injection pumps, air switching valves, air pump inlets/covers, gaskets/connectors/clamps and speed sensors.

The contact owns a 2005 Toyota Sequoia. While driving various speeds, the vehicle independently accelerated without warning. The vehicle was taken to an unknown dealer where it was diagnosed, but the cause of the failure was undetermined. The manufacturer was notified of the failure, but did not offer any assistance. The VIN and failure mileage were unknown.

I experienced a problem with engine warning and vsc trac off lights going on. The check engine light also came on. My family and I were on a trip and our Sequoia all of a sudden lost power. It slowed down dramatically even though the engine was fine. It was a very dangerous situation because we were on an interstate where the speed is 70 mph. I also experienced all the brakes making a massive grinding noise while going slow into a restaurant. (the brakes have less than 3000 miles on them. ) the parking brake light also comes on periodically.

I have vsc trac, vsc off, and check engine. If you give it a lot of fuel, it just sounds like it wants to go, but it doesn't translate into power in the rear end. I use my code reader and it showed codes p1441 and p1444. Says I may have: a) faulty vacuum switching valve (vsv) for air injection control circuit, b)faulty air switching valve number 2, or c)faulty vsv for air injection system. This is the second time this happened to my Sequoia, and this seems to be a recurring issues for Toyota Sequoia owners and in fact it is a recurring issues for other models as well. This cost me approximately $2200 last time and now 2 years later it is back for another $2200 to repair. It's all the over the internet about this vsc trac, vsc off, and check engine, it needs to be recalled!.

I get constant warning lights for brake, vsc and trac. This is a very common problem with the Sequoia. It shuts down those safety features.

When turning corners in motion, the traction control light illuminates causing a loss of braking and acceleration. There is now way to control the vehicles acceleration/deceleration until the light goes off. Typically last about 3-5 seconds. This happens frequently every time the vehicle is driven.

Was driving and vehicle slowed down to about 35 40 mph and would not accelerate pass 40. Was in motion on a city street.

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.

The contact owns a 2005 Toyota Sequoia. The contact stated that the brake warning light illuminated. In addition, the vsc track off and the check engine warning lights illuminated. The manufacturer was not notified of the failure. The failure mileage was 103,000.

Within the first two weeks, after purchasing the vehicle, the "brake" light, "vsc trac" light, and "trac off" light came on and there was a terrible grinding sound when attempting to stop. It was very hard to stop but luckily I was in a parking lot when it happened the first time. The "brake" light has continued to come on multiple times per week since may of 2015 and the other two lights still come on occasionally. In fact, on my 800 foot drive back from picking up my lunch today, the "brake" light was on. Each time the other 2 come on, it causes the breaks to grind and it is very hard to stop. There was just over 120,000 miles on the vehicle at purchase. I have read numerous forums online stating issues with this model, 2004, and 2003 models for the same issue but Toyota has refused to do a recall and expects customers to pay for something is obviously an issue throughout these particular models. I think something needs to be done about this issue. I believe it is a safety concern Toyota needs to be responsible for!!!.

Trac off, vsc trac ,engine light came on. . . Trouble code was p1444 (secondary air injection system switching value stuck). . . Vehicle had problems accelerating. Repairman indicated that the air injection pump/check values needed to be replaced and very expensive. Based on other reports it appears that this is a frequent occurrence and vehicles shutting down on interstates. Others have said that Toyota knows about this but won't issue an extended warranty, but offers for newer vehicles . Owned several Toyotas before this. . . This could be a deal breaker for future Toyotas.

Vsc trac, vsc off, brake, abs lights. . . All on, all at once. This has happened several times now. It comes on for a couple of days and then resets itself no codes found. This time it came on again and limited the speed to about 35mph while my wife was driving on a major highway. She was able to get it back home safely thank goodness. I have been reading about similar cases for this model and do not know what to do. Please help. We have just had it serviced about a month ago for timing belt replacement etc. This is my wife's primary vehicle and I can't afford to put any more money in this. Is there a recall for this with so many cases of the same issue I have read about?.

Trac off, vsc trac , abs and parking brake lights all came on and stayed on while driving. Vehicle has been doing this intermittently for about a month now on a regular basis. Has done it over the past couple years but maybe once every several months. Resets after vehicle is turned off. Looked up issue on internet and was surprised to find all the posts about this issue and the lack of Toyota to recall whatever is causing this issue.

While driving home on interstate 15 in California brake pedal would not depress. After several hard foot applications pedal finally engaged. This is after months of service on this vehicle for brake problems starting with spongy and inconsistent pedal and vcs, abs and brake lights coming on and staying on. Dealership replaced on board computer, brake booster, brake master cylinder, brake pads and problem still there. I am the original owner and bought this vehicle new. This is a serious problem and just a matter of time before an accident occurs. This vehicle is now back in the shop once again.

Driving vehicle and abs activates and stalls vehicle not allowing for acceleration pulsating the brakes and leaving me in the middle of the road for about 30/45 seconds. It has happen twice already same thing both times.

I was told the vehicle control and stability system was off. And is a common issue with this year make and model. Vsc and trac off light keeps coming on. Also secondarily valve stuck closed. P1445 & p1442 codes. Also another known issue for this vehicle year make and model. Toyota is aware but won't fix after certain miles.

After cranking the car and driving for a few minutes, the following lights on the dashboard appeared: vsc off / vsc trac / check engine light. I entered the on ramp to the interstate and could not accelerate past 40 mph. Had to pull over and let the car "reset". Attempted to re-enter the interstate and the flow of traffic but car would not accelerate beyond 40 mph and I had my 3 small children in the vehicle. Very terrifying experience. Drove to a dealership that advised me a secondary hose had to be replaced on the engine. Later determined that Toyota released a technical bulletin and are aware of this issue but will not issue a recall. It is an extremely costly part to fix. Parts alone are $3200.

My vsc, trac and brake light all came on all of sudden with a large boom sound. The car stalled on me in an intersection. The lights go off once car is turned off and then after turning car back on they will come on about 5 minutes after driving. Car loses power every so often now. Dealer said it needs a new computer.

My vsc trac, vsc off comes on all the time and don't go away. This appears to be a manufacture issue.

The brake light constantly goes on and off. Trac off, vsc trac and check engine lights all come on. A loud rattling noise coming from the front end of vehicle and vibration the engine will not accelerate randomly while driving and the trac control light goes on at the same time.

Slowing down to turn the vsc trac< trac off < check engine<brake lights come on. This has happened three times and I temporarily lose control of braking and excelleration. This is dangerous and nearly caused me to enter traffic in an intersection.

While driving, the brake warning light, vsc off light, and vsc trac light all came on. Pulled over and shut engine off. Restarted the car and lights were initially off but came right back on as soon as I started driving. Had advance auto parts hook computer to it, and it isn't throwing a code at all.

The brake light constantly goes on and off. Trac off, vsc trac and check engine lights all come on. A loud rattling noise coming from the front end of vehicle and vibration when starting up the vehicle. Engine will not accelerate randomly while driving and the trac control light goes on at the same time. I first experienced this while going up a mountain and needed to turn around because my vehicle started to decelerate even with the gas completely floored. I noticed that there are a lot of complaints for the same issue. Is Toyota waiting for a death to happen before they do something. This is a family vehicle and I'm transporting my 2 and 5 year old. Something needs to be done about this before something tragic happens!!.

Vsc trac, vsc off and abs lights all come on at once. I took the vehicle to my mechanic and he couldn't pull the code as it was off by the time I got there. Brakes had good pad left. The light came on 3 times today and went off just as unexpectedly.

The vsc, trak light and abs lights came on which in turn made the check engine light come on. They stay on continually. At first no code could be found. Then dealer stated that the ecu had to be replaced as well as air pump - both totalling over $3000. This is not the only Sequoia to have this happen. Other years have been recalled so why not the 2005 - or any other year since it seems to be an issue. I emailed and talked to Toyota. They have not heard of this problem and can not help with it's solution. Last Toyota I'll have.

Vsc off light keeps appearing on and off. Antilock braking is disable when the light comes on.

My 2005 Toyota Sequoia had the vsc light come on. We took it to the dealer who said that it was a code for the secondary air injection valve sticking open, but he also told us that they have replaced the valves before and it ended up being the pump. When pulling into traffic the vehicle went into "limp"mode which was very close to causing an accident with my wife and three children in the car. After reading about so many other peple with the same problem, it would seem that Toyota should be willing to fix this issue before someone is injured or killed in an accident. I now have a car that is not safe to drive.

2005 Toyota Sequoia sr5. My vsc trac light, abs, brake, lights come on periodically for no reason. I have read many others have the same problem.

Vsc trac, trac off, and parking park light come one and off intermittingly. They will come on while driving and sometimes when the car is turned off and then restarted. They will be off. . . But sometimes they are still on.

I noticed the vsc trac lights stayed on. The vehicle appears to drive fine for a while, then loses power. Dealer could not find any codes and reset it. How it does it all the time mostly about the 2 or 3 day after unhooking the battery. After doing my own research online I discovered that many Sequoia owners have experienced the same issue, but Toyota has refused to do a recall. This issue with vsc trac is a huge safety concern. Through my research I discovered that the vehicle could lose power at any time, and many owners state they hear a grinding noise as the vehicle pulls to the right or left. They recalled the 2003, what about us, a friend had a new computer epu put in at $3000 and did it again in 6 months. . . Toyota knows about this and other problems. . . We need a recall or have it fixed.

Started car and hear a loud whining noise but no lights came on. Within 2 days the whining noise was not heard when starting car but trac off, vsc light, and check engine light were all on. Took the truck to mechanic and he changed the battery and flushed the brake fluid. Lights were off for about 2 more starts of the truck and all lights were back on. Took it back to the mechanic the next day and he kept the truck for 2 days, called Toyota and they told him to replace the air injection driver. This was done 12 Nov 10 and by 13 Nov 10 all lights are back on again and the truck is having issues picking up speed.

In the past two weeks following a rapid braking my 2005 Toyota Sequoia surged forward upon acceleration requiring applying the brakes to stop the sudden lurching forward. This has occurred on three occasions over a ten day period.

This has been going on since April 2010, its now November 2010 with no resolution. My 2005 Toyota Sequoia trac off, vsc trac, check engine lights and abs lights keep coming on. Brought into the dealer three times while the lights were on so the dealer could put it on the computer. No codes show up. I am told that it's not covered even though we have the Toyota certified bumper to bumper warranty. They recalled the 2003 for the same problem. They need to do the same for the 05. Repair cost for this is $2200. 00.
