Vsc/trac and engine light came on. Dealer said problem was O2 sensor. They replaced 02 sensor and all lights cleared. After one week the vsc0/trac lights came back on and they go on and off every time we drive the truck. Dealer said we need to replace skid control ECU. We decided not to replace the unit because of $1800 cost.

Purchased new in 07/2003, on 9/21/08, our Sequoia with only 39,000 miles had its vsc trac, vsc off, & ABS lights come on for no apparent reason. There was a bad sensor and a bad ECU. We located tsb.BR006-06 for this problem where the recommended fix is replacement of the skid control computer because of a change in the software to correct the problem. This is a very expensive part. Toyota customer service would not help. My dealer wanted $1,300 for the ECU and $330 for the sensor, but I got them down to $940 for the ECU and $240 for the sensor. After tax it was about $1300, plus $255 for three hours of labor. This is clearly, in my opinion a software bug, since the new ECU has a new program as stated in the tsb. I'm pretty upset that a software bug isn't a manufacturing defect, but the responsibility of the vehicle owner. I'm going to approach an attorney to start a class action on this matter. Hopefully, it will be worth their contingency.

2003 Toyota skid control computer, I am writing to request that a formal complaint be filed to Toyota. I recently took my car into my local Toyota dealership because of a few lights that we on in my dash. The specific lights were the vsc, vsc off and the ABS lights. After doing some research I see that this is a fairly common problem with Toyota and their skid control computers. The problem is that it is not covered under the powertrain warranty and is a very expensive part to have replaced. My quote was for $1800 excluding tax. I purchased the vehicle with 47,000 miles and was offered an extended warranty up to 60,000, but it was a very expensive extended warranty so I decided to pass. The manufactures warranty for my car was 55,000 miles I believe and the lights came on at 55,500 miles....of course. I sincerely hope that there can be some sort of resolve for this such as a recall of the skid control computer or changing this issue to be covered under the power train section of the warranty as it is unfair for there to be so many people to be having the same problem around the same mileage and some of those people have serious consequences to the computers malfunction such as accidents and possible death. Please take whatever action necessary to solve this unnecessary issue.

Toyota Sequoia 2003, vtrac and ABS lights came up on the dash during a very wet interstate trek to Michigan from California. Had no cruise control before this, the cruise control failed the year before during the same wet trek across country! the Toyota dealer in saginaw Michigan told us that the computer controlling the vtrac and ABS was displaying fault codes and needed to be replaced, cost $1200. This is a 5 year old vehicle with 70K miles on it now (the fault happened around 66K miles) which is now much harder to handle under heavy braking, which we need more and more with the low quality drivers out there. If the gas prices weren't so high, this truck would be out of here here, but we can't afford to sell it for the current value, and buy another vehicle, so this SUV will now be limited to trips where we need the storage/towing capacity. So, even though we have 2 cars, we only really have 1 1/2 now.

The vehicle stabilization control compute failed for the second time and has taken out my ABS brakes. The computer that controls is has failed both times.

On 4 occasions dash light indicating vsc and brake problem appeared. Each time the braking of the 2003 Toyota Sequoia was compromised. Each time the truck was brought to Toyota service center for repair. Each Toyota said they could not replicate the problem but replaced skid computer anyway. 8/20/08 problem recurred with dash brake indicator light coming on. Braking again compromised, heard loud "clunking sound" coming from car while driving. Immediately brought to scottsdale Toyota service center. Again, said they could not replicate problem and returned car with no repair. Called Toyota customer service and filed a complaint. Toyota indicated complaint is now on record. Problem with dash brake light coming on and braking diminished recurred again 8/27/08. After shutting engine off, indicator no longer lit and braking back to normal. I fear for both my safety and my families. Simple google search indicates a large number of Sequoia owners are having the same problem.

I have a concern over why the ABS, brake, and other lights would come on for no apparent reason on my 2003 Toyota Sequoia. On some websites I have found that this is not an isolated problem. Wanting to know if action has been pursued for a recall in this matter. This occurs everyday, once the car is warmed up.

Toyota Sequoia 2003, bought new my complaint echoes what a lot of others are experiencing regarding the skid control computer which apparently affects the vsc/abc/ebrake. Problem was identified over a year ago with the ebrake light randomly coming on during normal driving (restarting the car usually resolves), but eventually got to a point where the car thinks it's in a vehicle skid control situation and ABS triggers and apply pressure to the gas pedal is inoperable. Extremely dangerous situation as we were driving through our neighborhood filled with kids (and have 2 of our own) seems to be a pretty significant issue out there someone needs to look into it.

I bought a used 2003 Toyota Sequoia in 2004. It currently has 30130 miles on it. I am the second owner. The problem: Sporadic vsc/atrac malfunction. 1. I had been advised to go in for Toyota campaign ssc 50J for ball joint safety recall. This was done at fremont Toyota on May 30, 2008. 2. on June 12, 2008, the vehicle skid control and traction control starts disengaging on its own, while I was driving the vehicle on us 101 North freeway on my way home from a trip to monterrey bay aquarium. 3. description of the problem: The vsc/atrac indicator lights changes state to on and the system will inadvertently engage and disengage without any warning. To reset, I had to pull over to the side of the freeway and restart the vehicle. The problem repeated a dozen times, until I reached home. So I took the vehicle in to fremont Toyota on June 14, 2008 and was told there is error code C1231 and C1203 and the reason is faulty engine and traction control computers. 4. I was not convinced with the answer and decided to do my own research on the NHTSA site and discussion forums on the net and found out that to solve this issue, Toyota modified its skid control logic and the vsc communication between skid control computer and the engine control module to rectify this problem (please refer NHTSA# 00303 & BR00203, diagnostics codes C1231 & C1203). 5. I called up fremont Toyota in California about what I found out and was told by the service advisor that I had to replace the existing vsc & ECU computers, with updated/redesigned modules at my expense (costs of $2700) I think this is unreasonable since, I consider this a manufacturing defect since the fix calls for a computer upgrade. I am writing to let your office know that Toyota dealer and Toyota North America will not acknowledge this problem. I can be reached at (510) 471-6937 if you have further questions. Sincerely, shaji ravindranathan

Toyota Sequoia vsc ABS problem on this 2003 Sequoia the ABS brakes intermittently come on without warning, and with out the driver braking. This has happened only at slow speeds thus far. The vsc indicator lights also come on.

2003 4X4 Toyota Sequoia / 30K miles. One more complaint about the vsc/trac-ABS lights coming on due to faulty vsc computer. My vehicle only has 30,055 miles and is still under the manufacturer's 60 month/60,000 powertrain warranty yet this is not covered. Very expensive repair in excess of $2,000. This complaint has been filed by thousands and really should be a recall as to its impending danger it puts the drivers in.

Vsc/ABS/skid control computer failure at 50,000 miles in 2003 Toyota Sequoia SR5 2wd. This is a widely known problem, for which Toyota proposes replacement at consumer cost of $1500+ for out of warranty vehicles. Requested outcome: Toyota should replace the computer at no cost for part; this is clearly a defect and should not be required for consumer to replace.

Vehicle stability control lights came on. The dealer says that the engine control computer must be replaced. The part alone is $2,100, then labor to install. I have read numerous other reports of failure of this component which seems integral to the vehicle's steering and handling. Toyota published a technical bulletin in May 2006 recognizing this defect and changing the skid control computer.

I own a 2003 Toyota Sequoia limited with approximately 57, 000 miles. I recently took my vehicle to Toyota of huntington beach for service and to check on the vehicle skid control (vsc) light because it would not turn off. The service advisor stated that based the diagnostic repair codes and a repair bulletin, he recommended a that the skid control ECU be replaced at a cost of $1667 this repair recommendation what disappointing for a number of reasons: 1.this is a repair that should have been made while the vehicle was under warranty. I have previously complained about the vsc light to a Toyota service technician while the vehicle was under warranty. The solution by the Toyota of long beach repair facility was to simply 'reset' the ECU. Attached is the invoice. 2.secondly, the ECU is not a wear and tear item and is not subject to ongoing maintenance. It is a computer chip that is designed to control the vsc, etc. 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 recall. 3.the design flaw is serious and critically affects the safety and stability of the vehicle. 4.finally, the ECU is essentially a small computer and the $1600 price tag to replace such and inexpensive part is absurd. In the event that Toyota does not honor its commitment to quality, Toyota, should reevaluate the pricing of such a small but critical part and repair.

Vsc/ABS skid control ECU failure on 2003 Sequoia @ 56,410 miles (orignal owner). ECU failure is a known issue by every Toyota Sequoia owner, but Toyota claims it's limited. This failure requires that vsc/ABS skid control ECU / yaw rate sensor be replaced. The repair cost was $794.20 for part and labor at the local Toyota dealer. Now, considering the severity of the defect and number of complaints on this site I'm very suprized not to see a recall notice to date.

2003 Toyota Sequoia SR5 90,000 miles - since I purchased this vehicle brand new in July 2003, the vsc trac, vsc off and brake lights have turned on by itself intermittently. Until the weekend of Dec 22, 2007, I regarded this issue, more or less, as a nuisance problem. On Dec 22, 2007 the vsc trac and vsc off lights came on and pretty much have remained on. On two occasions, the slip indicator light started to blink, causing a loud noise and vibration by the operation of the brakes.

1.) no events leading up to failure 2.) vsc off / trac off lights on dash stay on continually, and vehicle stability control is effectively disabled. Researching this issue on the internet finds that this is a common issue. 3.) Toyota dealer is recommending replacement of the vsc ECU (stability control/traction control computer) at a cost of $1500-$2000. Based on the numbers of these reported incidents, I feel this is a defect and is an exorbitant amount to be paid by the owners of these vehicles.
