Filed Jul 29, 2022 · Acceleration, Brakes · WA

"VSC OFF, VSC TRAC, and ABS" indicators on the dash. YAW sensor failure which controls wheel speed which will cause vehicle to decelerate and possibly cause an accident. Toyota should issue a nationwide recall. Toyota is aware of the issue but has failed to issue a nationwide recall.

While executing a slow speed left turn(10-15mph) I braked lightly to execute another left turn when the parking brake and traction control lights lit up on my dashboard along with diminished brake power and a grinding noise. I applied them again a little more aggressive to stop my vehicle..same response. I coasted to about 2-3mph and the lights were still showing but I recovered brake power. At my destination(3 blocks away) I turned off the vehicle. On my return trip back home, there was no sign of dash warning lights and I had full braking power. @home I immediately called toyota USA and they did not acknowledge any ongoing problem. After going on an online forum I discovered numerous complaints about the same problem...some of them actually going to toyota for the problem, and some of those stated the problem returned..my son ran an obdii diagnostic to find numerous codes for the ABS ans ecu and brakebooster system.fixes range from low brake fluid to a complete replacement of said systems costing thousands of dollrs. I feel this is a serious safety issue that toyota should address. [dateline problem happened 6-27-19...]I have no choice now but to warily trust toyota to run a diagnostic on my vehicle for solutions....please help

Vsc and ABS lights have been on and stability control is off. This has been in this state for several years and I have had several unsuccessful interactions with toyota regarding repairing under the recall. My car was manufactured in may. The recall only covers cars manufactured through april. Having worked in a toyota plant for 5 years, I know that it is very possible that the defective parts could be in the plant several months past april. Yesterday, my braking system was not operating properly. The ABS was activating randomly, when driving at slow and highway speeds, and the car was not reacting normally to the accelerator pedal.. I took the car to a mechanicm. The troubleshooting codes had to due with the stability control computer.

I went outside and turned the car on and noticed that the ABS, vsc off, and vsc trac dashboard lights came on and did not turn off. I drove the vehicle around the block and the lights remained on. This is a known manufacturer defect with the computer that controls the ABS / vsc trac system on the 2003 sequoia. I have had the computer modules replaced for this issue before and 60,000 miles later the same parts have gone out again. It is unsafe to drive an SUV with the vehicle skid control and ABS systems not functioning.

Skid control ecu issue...my 2003 recently started having a failure in the ecu and causing the vehicle's brakes to go into ABS mode randomly during acceleration and not stop properly when applying the brakes. The brake light, vsc off and trac off all go off and the brakes go out and almost cause me to wreck. I have read online that this has been an on-going issue with this vehicle, and I'm curious what toyota is doing or not doing to fix this. I had the ecu recall "software upgrade" back in 2011. They only warrantied the work for 1 year, well now my computer is failing and replacement is $1500. This is a formal complaint because it seems that I could have had a replacement ecu years ago and I wasn't informed

My vehicle has an issue with the ABS skid control. When the mechanic ran the check it came back with error codes c1203, c1223, c1247. I purchased hated this vehicle because I have a growing family and I needed the third row seating.the problem with the braking system happens when I have to stop quickly, which is a a safety concern. I believe there is an issue with the computer and the skid control or anti locking brakes.

While I was driving at an approximate speed of 40 MPH, I noticed my brake, trac off, vsc trac, engine light all came on at once. I noticed that braking was not as responsive (increased braking distance; ABS doesn't seem to be engaging) and when speeding to over 50 MPH, the vehicle feels as if it is slowing itself down. It is currently an expected heavy rainfall season where I am and having the vehicle in this state is very dangerous especially when the brakes are not working effectively or when it starts to slow itself down suddenly. After shutting the vehicle down and restarting it after about 2 hours, the lights mentioned are still illuminated except the brake light. After reading all the other similar complaints, I am surprised toyota is not paying for all aspects of this defect associated with the vehicle and not driver misuse.

Vehicle stability control (vsc), traction control (trac), and antilock brake system (ABS) dash lights continuously illuminated indicating that all systems are off or malfunctioning. Can confirm that the trac, vsc, and ABS are inactive all or most of the time. The ABS intervenes at random under normal braking conditions without cause at low speed (less than 20mph) and makes braking difficult and inconsistent in conditions where ABS is not normally needed. In that situation the brake pedal becomes hard to depress and braking force is inconsistently applied with little control given to the operator in turn extending the braking distance without due cause or warning. After much research online I have found numerous reports stating identical and/or similar observations and experiences. It is my opinion that the problem lies in the vsc control module, a known problematic component on this generation of sequoia and more specifically model year 2003 vehicles. A recall for the vsc system was issued in april/may 2010 upgrading the control logic of the vsc system in certain model year 2003 vehicles. Let it be known that the vehicle in question had the recall work done in june of 2011 which did not remedy the issue as it has been either intermittent or constant since then.

When driving on the freeway the ABS, vsc trac and brake light all came on at once. Since then I notice a problem when I brake at higher speeds the car seems to shake as though the ABS is not being applied properly. The dealership said there was a recall on this which was a simple software update. Now the dealership tells me these parts need to be replaced. How do I know that a simple update is not the fix or that the new parts wont have a similar issue in the meantime I am stuck with a vehicle that's not braking properly when it seems this should be fixed by the manufacture

Tl* the contact owns a 2003 toyota sequoia.

I went to toyota on 2013 to have my car reflash (the vsc off, vsc trac and ABS litghts for recall 10v176000) to remedy the situation, after doing so when I went to pick up my car the lights where still on and the service advisor told me I need to pay to have the car checked at the computer and since I didnt have the money to pay for it my car wasnt checked. The ligths are still on, call toyota but they say there us nothing they can do. Since this was a problem originated by a faulty part I dont see why they dont want to take care of it. Besides the price tag for that repair is 2,000.00 just for the part. Please help.
