NHTSA Complaint #10030648 — 2003 TOYOTA 4 RUNNER

WHEN ACCELERATING THE ENGINE MAKES AN ODD NOISE THAT SOUNDS LIKE THERE IS AN EXHAUST LEAK. I ALSO INTERMITTENTLY HAVE THE "ROTTEN EGG" SMELL INSIDE THE VEHICLE. I TOOK IT TO THE DEALER TO HAVE IT EXAMINED AND AFTER THE SERVICE MANAGER DROVE THE VEHICLE FOR 1.6 MILES, HE TOLD ME "THEY ALL SOUND LIKE THAT." IT SEEMS ODD TO ME THAT A VEHICLE DESIGNED TO BE SO QUIET WOULD MAKE SUCH AN ALARMING SOUND WHEN ACCELERATING. I ALSO FIND IT ODD THAT, IF THERE WERE NO EXHAUST LEAK, WITH ALL THE WINDOWS CLOSED, THE ROTTEN EGG SMELL OF EXHAUST IS STILL ABLE TO SEEP INSIDE THE PASSENGER COMPARTMENT. I HAVE READ OTHER COMPLAINTS STATING CUSTOMERS SHOULD USE A "BETTER QUALITY" OF FUEL. I HAVE ONLY USED HESS AND MOBIL 93 OCTANE IN THE 3 WEEKS THAT I'VE OWNED THE VEHICLE. I ASSUME THIS IS A GOOD QUALITY GASOLINE, BUT IF TOYOTA FEELS THERE IS A BETTER QUALITY GASOLINE WHICH WILL MAKE RESOLVE THESE PROBLEMS, I WILL BE HAPPY TO USE SPECIFICALLY THE BRAND THEY RECOMMEND.*AK
