2002 Toyota Sequoia electrical system problems

“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.”

THE MECHANIC ALSO STATED THAT THIS IS VERY COMMON PROBLEM WITH SEQUOIA MODELS BUT THERE IS NO RECALL OR WARRANTY FOR THIS PROBLEM AT THE TIME IT WAS DIAGNOSED.
