2005 Toyota Sequoia traction control system problems

“TRAC OFF, VSC TRAC ,ENGINE LIGHT CAME ON...TROUBLE CODE WAS P1444 (SECONDARY AIR INJECTION SYSTEM SWITCHING VALUE STUCK)...VEHICLE HAD PROBLEMS ACCELERATING. REPAIRMAN INDICATED THAT THE AIR INJECTION PUMP/CHECK VALUES NEEDED TO BE REPLACED AND VERY EXPENSIVE. BASED ON OTHER REPORTS IT APPEARS THAT THIS IS A FREQUENT OCCURRENCE AND VEHICLES SHUTTING DOWN ON INTERSTATES. OTHERS HAVE SAID THAT TOYOTA KNOWS ABOUT THIS BUT WON'T ISSUE AN EXTENDED WARRANTY, BUT OFFERS FOR NEWER VEHICLES . OWNED SEVERAL TOYOTAS BEFORE THIS...THIS COULD BE A DEAL BREAKER FOR FUTURE TOYOTAS. *TR”

“WHILE DRIVING STRAIGHT DOWN THE STREET, I HEARD A GRINDING SOUND AND ALL OF THE VSC TRAC WARNING LIGHTS CAME ON. AFTER STOPPING AND RESTARTING THE CAR, THE CAR BEHAVED NORMAL AGAIN. THIS IS THE SECOND OCCURRENCE. I'M PRESUMING THAT THE GRINDING NOISE MIGHT BE THE BRAKES PULSATING. IT IS NOT SAFE FOR THE BRAKES TO AUTOMATICALLY APPLY THEMSELVES DURING SAFE DRIVING CONDITIONS. *TR”

“MY VSC, TRAC AND BRAKE LIGHT ALL CAME ON ALL OF SUDDEN WITH A LARGE BOOM SOUND. THE CAR STALLED ON ME IN AN INTERSECTION. THE LIGHTS GO OFF ONCE CAR IS TURNED OFF AND THEN AFTER TURNING CAR BACK ON THEY WILL COME ON ABOUT 5 MINUTES AFTER DRIVING. CAR LOSES POWER EVERY SO OFTEN NOW. DEALER SAID IT NEEDS A NEW COMPUTER. *TR”

“THE VSC, TRAK LIGHT AND ABS LIGHTS CAME ON WHICH IN TURN MADE THE CHECK ENGINE LIGHT COME ON. THEY STAY ON CONTINUALLY. AT FIRST NO CODE COULD BE FOUND. THEN DEALER STATED THAT THE ECU HAD TO BE REPLACED AS WELL AS AIR PUMP - BOTH TOTALLING OVER $3000. THIS IS NOT THE ONLY SEQUOIA TO HAVE THIS HAPPEN. OTHER YEARS HAVE BEEN RECALLED SO WHY NOT THE 2005 - OR ANY OTHER YEAR SINCE IT SEEMS TO BE AN ISSUE. I EMAILED AND TALKED TO TOYOTA. THEY HAVE NOT HEARD OF THIS PROBLEM AND CAN NOT HELP WITH IT'S SOLUTION. LAST TOYOTA I'LL HAVE. *TR”

“BRAKE LIGHT INDICATOR INTERMITTENTLY CAME ON OVER SEVERAL MONTHS (JAN - MAY 2011) AND AT VARIOUS SPEEDS. SOMETIMES AT STARTUP, OTHER TIMES AT HWY SPEED. SINCE FLUID WAS FULL AND CLEAN, DID NOT TAKE CAR IN RIGHT AWAY. MENTIONED TO DEALER AT 60K MI. SVC TO DIAGNOSE. TOYOTA DEALER DIAGNOSED THE SOURCE OF THE PROBLEM WAS A MALFUNCTIONING "ELECTRONIC SKID COMPUTER." COST $122 TO DIAGNOSE AND $1120 TO REPLACE. I UNDERSTAND THIS COMPUTER CONTROLS THE STABILITY CONTROL AND ABS SYSTEMS, SO IT IS A POTENTIAL SAFETY HAZARD. *TR”

“AFTER I HAVE DRIVEN MY 2005 TOYOTA SEQUOIA FOR APPROX 20+ MILES, WHEN I APPLY THE BRAKES THE ABS, BRAKE, TRAC, VSC, ETC. LIGHTS ALL LIGHT UP ON THE DASH. WHEN THIS HAPPENS THE SUV BECOMES A LITTLE HARDER TO CONTROL. IT WANTS TO PULL TO ONE SIDE WHEN APPLYING THE BRAKES. IF YOU STOP AND TURN OFF THE SUV AND RESTART THE LIGHTS GO OFF. MOST OF THE TIME THE LIGHTS WILL COME ON A SHORT TIME LATER. I CONTACTED TOYOTA IN JULY OF 2009 AND THEY TOLD ME TO TAKE IT TO THE DEALER. I WOULD HAVE TO PAY TO HAVE IT FIXED SINCE MY WARRANTY HAD EXPIRED. I HAVE BEEN DOING RESEARCH ONLINE AND THIS IS A BIG PROBLEM WITH MANY SEQUOIA OWNERS. TOYOTA DOES NOT SEAM TO HAVE AN ANSWER FOR THIS ISSUE. *TR”
