Vsc/ABS skid control ECU failure on 2003 Sequoia. ECU failure is a known issue by every Toyota Sequoia owner, but Toyota claims that it's not an issue. This failure requires that vsc/ABS skid control ECU be replaced at a cost of $1300 - $2100 depending on location. This should be recalled by the manufacturer or, by government intervention due to the severity of the defect and the potential for accidents and/or death resulting from the defective computer system causing the vehicle to lock up and lose power.

Vsc and trac and ABS lights come on 2003 Sequoia with 38,000 miles for no reason. Dealer says yaw rate sensor bad but have had problem with these lights since purchase in 2003. Apparently, many Sequoias from 2001 to present have problems like this. Toyota needs to be do something.

This is a complaint to nhsta regarding vsc/ABS skid control ECU failure within a 2003 Toyota Sequoia. This issue occurred around 60,000 miles and, unfortunately, the dealer claims no responsibility for this, nor will they cover/repair the part, although numerous complaints have already been made by other Sequoia owners about this same issue. I have spoken to the dealer numerous times about this issue previously, and they said that it was nothing to worry about. It seems rather unfair to foot a bill of $2500 for a part that failed due to Toyota and not me, the consumer.

2003 Toyota Sequoia - almost crashed when a malfunction with the vehicle skid control ECU occurred. Caused car to lose power, brake fluttered and made grinding noise, and alarm sounded in cabin of car. Trac off and vsc trac lights came on. Thousand oaks Toyota (ca) pulled codes C1203 and C1231. Quote for repair = $2100 (to replace trans late ECU and skid control ECU). Unfortunately, I have 41K miles on it and warranty ended at 36K (36 months was up in December of last year). Many reports of same problem in Sequoias on various websites. Toyota is refusing to pay for repairs. Car has not been repaired at this time.

When we first bought the vehicle the trac system lights kept coming on and the brakes felt mushy; we took it in to Toyota and they replaced the computer system which seemed to rectify the problem. Then about 9 mo to a year later the lights kept coming on again and the brakes failed twice, Toyota stated they would replace the brake system fluid and the master cylinder at our cost because we had taken it elsewhere and they felt that it had contaminated brake fluid, which our mechanic stated in writing was not. Although we tried numerous times to have Toyota fix it under warranty; we got the vehicle repaired through our own mechanic and then shortly later the brakes failed resulting in a crash on the freeway. When it was decided that the seq would be repaired via ins there was a code that showed up on the computer system that showed that brakes indeed did fail; however when taking it to Toyota the same code did not show up. The vehicle did well, however we live by a dirt road and when traveling down the road or going around a corner quickly the trac system lights go on and now the vehicle acts like it won't go when the trac system is on and you slow down or start up again--at present the system is turned off; it has really never worked correctly.

Toyota Sequoia - consistent failure of the traction control system while driving. This issue has been addressed by the dealer multiple times to no successful repair. We also have had significant issues with the rear window seals leaking and causing the window motor to fail.

Sequoia 4WD 8-cyl

  • Automatic transmission
  • 44,700 miles
Vsc/trac lights comes on when taking right hand turns causing complete power loss of vehicle or anti-lock brakes to grind vehicle to a halt. Had a very serious near miss accident when turning at intersection. Vehicle shut down and car behind me nearly rear ended me. I have located 3 tsb's related to this very serious safety issue. Entire computer module needs to be replaced at a cost of $1500 to me. Dealer says warranty expired and refuses to accept blame for faulty part.

Sequoia 4WD 8-cyl

  • Automatic transmission

Brake system will grab and throw car into skid, but parts are failing intermittently. The switch on the dashboard does not shut it off. Consumer had no control of vehicle. It has been in the repair shop, and found out steering angle sensor was bad, and replaced it. Also, computer was defective. The vehicle's computer was replaced also. The technician could not confirm what failed first, why either failed, or why he could not find any trouble over one year ago, when consumer noticed blinding lights on the dashboard. The consumer feels that this is a safety hazard because drivers do not have control over this active 4 wheel drive system. Also the dash control will not shut off vsc (vehicle skid control), nor any other fuse, switch, wire, or other vsc's.

While consumer was driving the check engine light/trac light, and ABS braking light appeared on the dashboard and remained on. Then, vehicle stalled. Consumer was unable to restart vehicle, and had vehicle towed to dealer for inspection. Mechanic determined that the battery needed to be replaced. Consumer informed mechanic that this problem recurred and had not been resolved.
