Regarding a '04 Honda Sequoia, the vehicle stability control system -- which is a traction control that interrupts engine ignition to slow wheel spin -- has frequently been activating when unnecessary. The result is that the vehicle slows dramatically when surrounding traffic is moving at a much higher speed. This occurs frequently. The vehicle is owned by my 36-yr.-old son, and I've been in the vehicle, with my 1-yr.-old grandson, when it malfunctions. It is unnerving and unsafe to be on an interstate highway -- I-196, Michigan -- and to suddenly slow to a crawl with surrounding traffic -- including semis -- zooming by at high speed blowing horns and gesturing(I couldn't agree with them more). I retired from GM world hq in detroit as a senior executive with nearly 30 years experience in manufacturing, public affairs and media relations. My plant and divisional experience includes fisher body, Buick and detroit diesel allison. At the corporate level I've worked in our Washington, D.C., office, and, of course, detroit. In fact, I was at Buick when traction control first started being explored. What we lacked back then was computer horsepower necessary to deal with wheel speed input and proper ignition interrupt. In any event, I know an unsafe condition when I see it...such as going slow when everything else is going fast. I have a feeling, too, that my son's vehicle is not a one-of-A-kind situation. P.S. your listing of models didn't include the Sequoia SUV, so I checked "Pilot".

Same problem as everyone else...vsc, ABS, trac and check engine lights come on. Need to pull over to the side of the highway, turn off my vehicle and restart it to turn off the lights...I manage an independent repair shop and have seen several more Sequoias come in with the same problem. The before mentioned lights have come on a handful of times in my personal vehicle. When is this issue going to be taken seriously"?? hello Toyota" unfortunately it will take several deaths to get this issue taken care of....shame on Toyota. Do the right thing! chalk up another dissatisfied "vsc victim."

2004 Sequoia 77K miles / vsc off / vsc trac / ABS lights on all at once. Issue has been associated with a check engine light since new purchase in Aug 2004, most of the time the issue was resolved after loosen the gas cap and filling up the gas tank which usually cured my issue. Each time I had the vsc off and vsc trac / ABS issue I had taken it to the dealer which after the vehicle was restarted the errors were not present, ," it has returned occasional over the years and dealt with it due to it resets itself - presently it is solid after a few weeks of rain here in South Florida took it to the dealer today which they quoted me $1340.24 plus $185.76 in labor.." I refused the repair until I could further research this issue by searching for 4 hours I have found that this issue is a trend for Tundra, Sequoias, land cruisers from 2003 to 2005 which this stated to be a default in the skid control unit as a factory defect - by this apparent trouble this should be a recall of the skid control unit ( ECU ) to current Toyota owners that is affected. I have placed my complaint with Toyota hq of this issue awaiting call back from the dealer. Updated 03/18/10 the consumer has decided to trade the vehicle. Updated 05/05/10.

2004 Sequoia with 75,000 miles. Driving down road in the middle of the summer and ABS light comes on and the brakes went into anti skid mode. Very scary and had the kids in the car. Had to pull over and turn off the car. The vsc and ABS lights are staying on. Took car to dealership and they know it is a known problem. They want to charge us $1400 to get it fixed.

I have a 2004 2wd Toyota Sequoia. The vsc light keeps coming on. Reading on edmunds.com and tundrasolutions.com I have found that this is a common problem and should be grounds for a recall. One of the SUVS even caught fire.

My 2003 Toyota Sequoia has 2 lights that come on when I drive (the vsc and trac off). Sometimes it comes on immediately after I start the car, other times it comes on after driving for about a minute. The Toyota dealership diagnosed it as needing a new skid control ECU. They told me that this computer controls the ABS of the vehicle and that it is unsafe to drive. However, the price tag is too steep to have repaired today.

We were experiencing occassional dash brake light illumination about every two weeks or so. When I had the vehicle in for another issue, I mentioned the brake light. Toyota told me that they needed to replace the skid control computer and the vehicle was unsafe to drive while the light was on. After having the computer replaced, the brake light came on two more times while we were out of town. The next day as I was starting to slow approaching a turn the truck suddenly braked very hard and it felt like we were going to start skidding. This was an unexpected automatic application of the brakes and proved to be extremely dangerous. Luckily for us there were no cars following at the time. This episode illuminated the brake light along with the vsc and trac lights. Whatever Toyota replaced not only didn't solve the problem, but apparently made the vehicle more dangerous to drive. It is now at Toyota for further diagnosis. I see that this is not an uncommon issue, as there are numerous complaints about this system on the Sequoias. There should be a developed repair plan to remedy this situation and to keep their customers safe.

Vsc lights come on intermittently, took to dealership and they said no problems were found. Over the next few years they still come on periodically. I have to shut the vehicle off and then the light goes out.

I have a 2004 Toyota Sequoia. The vsc, trac and emergency brake lights come on. If I turn the car off and then turn it back on then the lights will go off. This has been going on for one week now. I took it to the dealer and they want $2100 to fix the computer. Apparently, this is a widespread problem with the Toyota Sequoia.

Vehicle has faulty vsc computer. After researching this problem, I noticed several identical complaints. As a result of the extent of the complaints, I feel there should have been a recall from Toyota to address this problem. I do not have $1615 to fix it.

I bought a new 2004 Toyota Sequoia limited in may '05. Roughly 6 months into ownership - my brake light, vsc (traction control) and track off lights came on intermittently. I had my brakes replaced in Dec '07 and this seemed to clear up the issue. In Sept '08, my brake light started lighting up again intermittently and on 12/1/08, my vsc and track off lights came on and stayed on. I brought it to my Toyota dealer for service and they are telling me that my skid control computer needs to replaced to the tune of $1800. After doing some research, it appears that this is a very common issue and has been going on since 2002. The failure of these systems leaves me without ABS and without vsc (two of the reasons I bought the car I did) and at an increased risk of having an accident. I would like an investigation done on this component to determine if a recall is warranted.

2004 Toyota Sequoia vsc computer and bank sensor failure dashboard lights came on dealer examined - says skid control ECU and bank sensor need to be replaced.

- Richmond, VA, USA

Vsc, ABS and brake lights in dash come on and do not go off. After dealer inspection it was determined that the traction control module needed replacing. This is a very expensive part that is critical to the safety of the braking system and should be reviewed as a recall item on this model.

I own a 2004 Toyota Sequoia with 35,500 miles. I recently took my vehicle to Toyota to check on the vehicle skid control (vsc) light, vsc track light and the check engine light because they would not turn off. The service advisor stated that based the diagnostic repair codes and a repair bulletin, the skid control ECU must be replaced at a cost of $1668.90 this is very disappointing and Toyota's are looking less than good at the moment. The ECU is not a wear and tear item and is not subject to ongoing maintenance, it's a computer chip that is designed to control the vsc. If the ECU can not be reprogrammed to function as intended, then this design flaw that again should have been replaced under warranty or as a recall. The design flaw is serious and affects the safety and stability of the vehicle. Finally, the ECU is essentially a small computer and at a high price tag to replace such and inexpensive part is absurd. I own 3 Toyota SUV's and if Toyota does not honor its commitment to quality, then I will not keep, purchase, nor recommended a Toyota again. I hope Toyota does the right thing and issue a recall for this problem. Thanks

*******2004 Toyota Sequoia ltd vsc computer failure, wheel lockup on left********* brake light, vsc and trac light all came on. I was driving approx. 20 mph and the left front wheel locked up and the car pulled sharply to the left. The brake pedal went to the floor and I lost brake pedal effectiveness. I turned the car off and restarted it and all lights went out and brake feel and effectiveness appears ok. I took the car straight to the dealer for inspection. For the last 2 years the brake light would come on and stay on and when I turned off the car and restarted it the light would go off. For 2 years my local dealer in butler, pa could not get a failure code. When I took the car for diagnostics, the cause was the ECM part number 89541-OC062 at a cost of about $1377. They replaced it at the great dealership in langhorne, pa. I have 55,659 miles on this vehicle. Since the repair the brake warning light has come on one time and stayed on, when we restarted the car it went away. I will return to dealer to have this checked again next time it comes on. It seems to me that this lockup of the wheel and loss of braking effectiveness is a real big safety issue on these vehicles. Please get back to me to tell me if NHTSA is looking into this situation. Thank you!

2004 Toyota Sequoia skid control ECU had to be replaced by the dealer as the ABS light continually light ups on my vehicle.

- Midland, TX, USA

I have a 2004 Toyota Sequoia. With just over 52,000 miles, the emergency brake light would come on for no apparent reason. The only way to get it to go off would be to stop and restart the vehicle. The local Toyota dealership advised us to check the brake fluid. It was fine. When I took my vehicle in for routine maintenance, they informed me that the anti-skid ECU computer component was going out. They said it wasn't a safety issue; however, we feel like it most definitely is a safety issue. Sequoia's are prone to roll over in accidents, and the anti-skid function is critical. We have done research, and it is obvious that Toyota is aware that it is a problem. Despite their knowledge of the problem, a recall has not been issued. Is it going to take major accidents or deaths of innocent passengers to get Toyota to issue a recall? because of the safety factor, we ended up spending $1,507.48 in order to have this replaced. With less than 53,000 miles on a Sequoia, it is ridiculous to have to spend that amount of money. The original anti-skid ECU is obviously defective; Toyota needs to do the right thing and issue a recall.
