NHTSA Complaint #11098609 — 2004 TOYOTA 4RUNNER

ON FEBRUARY 10, 2018, I WAS DRIVING MY 2004 4RUNNER IN A SNOWSTORM IN 4WD HIGH WHEN THE CHECK ENGINE LIGHT SUDDENLY CAME ON AND THE STABILITY CONTROL AND TRACTION CONTROL SYSTEMS IMMEDIATELY SHUT DOWN, CAUSING THE REAR OF THE VEHICLE TO START SLIDING AND PUTTING ME ON A COLLISION COURSE WITH ONCOMING TRAFFIC. I DON'T UNDERSTAND WHY TOYOTA DESIGNED ITS VEHICLES TO SHUT OFF THESE CRITICAL SAFETY FEATURES WHEN THE CHECK ENGINE LIGHT COMES ON. I SUGGEST THAT TOYOTA BE REQUIRED TO DEVELOP A SOFTWARE UPGRADE AND VOLUNTARILY RECALL THE AFFECTED VEHICLES TO INSTALL THE APPROPRIATE SOFTWARE FIX. I WROTE TO TOYOTA ON FEBRUARY 13, 2018 (SEE ATTACHMENT) EXPRESSING MY CONCERN. THREE AND A HALF MONTHS LATER, I HAVE YET TO RECEIVE EVEN A CURSORY RESPONSE FROM TOYOTA. THEREFORE, I FEEL I MUST NOW NOTIFY NHTSA OF MY CONCERNS.
