2002 Toyota Sequoia electrical problems

Filed Aug 30, 2025 · Electrical, Steering · NV

I was driving my 2002 Toyota Sequoia on the freeway at approximately 65 mph on the [XXX] when suddenly the vehicle made a beeping noise and the VSC Light and TRAC Light came on. The vehicle suddenly lost control in the wheels and tires and suddenly decelerated out-of-nowhere. Due to the sudden, abrupt movement and loss of control, the vehicle nearly flipped over. It was an extremely dangerous, possibly life-threatening situation. Thankfully, I was attentive and alert and had both hands on the wheel and was able to get the vehicle in control. This happened before two times and this would be the third time. I have taken the vehicle to several different auto repair shops and they have been unable to pin point and fix the problem. Because this issue continues to happen and puts me into dangerous situations repeatedly, I firmly believe that this is a bigger malfunctioning/defect problem that Toyota needs to address and fix.

Vsc, ABS, traction control and brake warning instrument lights on. Abs and traction control and vsc are inoperable due to a computer malfunction. This is an extremely common issue with first generation sequoias. My specific codes are c1241 and c1203. Toyota told me I will need a new computer to controls those systems at a 921 dollar expense. These issues have been ongoing since 2009.

My father and I were leaving frys electronics on friday may 19, 2017. As we turned from the fry's parking lot to head on the 60 fwy all of a sudden the vsc started beeping and just as we we picking up speed(50mph) the truck started to swerve while at the same time a grinding sound went off my father pushed the vsc off switch but did not have any effect on what was happening. When the beeping had stopped both vsc off and vsc lights had stayed on and the vehicle seemed to be running ok and ever since that day whenever we use the sequoia the lights come on and stay on during the trip on occasions it doesn't turn on after about 5 mins the beeping goes on and vehicle engine immediately slows and grinding sound goes on and causes vehicle to swerve and my father is a bit elderly so as a son I am putting in this complaint in hopes of some assistance in repairs this malfunction.
