EMERGENCY BRAKE: E-BRAKE APPEARS TO ENGAGE ON ITS OWN AND THE BRAKE LIGHT INDICATOR COMES ON. THERE'S ALSO A GRINDING SOUND WHEN BRAKE IS PRESSED. GRINDING SOUNDS ONLY OCCURS WHEN THIS ISSUE COMES UP. EXHAUST MANIFOLDS: WAS NOTIFIED BY THE DEALER UPON A SERVICE INSPECTION THAT THERE WAS A SMALL CRACK IN THE EXHAUST MANIFOLDS. IS THIS A NORMAL THING? AND SHOULD THIS BE A RECALL ITEM AS IT COULD THROW OFF ANY SMOG CHECK TESTING. IN ADDITION HOW ABOUT THE EXHAUST IN THE CABIN ISSUE? MAYBE THEY USED TOO THIN OF A METAL FOR THE MANIFOLDS.

THE VEHICLE DIED WHEN AT A STOP LIGHT AND ROLLED BACK HITTING THE CAR BEHIND US. I LOOKED ON YOUR WEBSITE AND APPARENTLY IT WAS CAUSED BY A FAULTY ENGINE CONTROL MODULE (ECM) IN THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM). THIS APPEARS TO HAVE BEEN RECALLED ON ALL 2004 TO 2006 INFINITI QX56 VEHICLES, HOWEVER, I RECEIVED NO SUCH NOTICE AND INFINITI SAYS THEIR IS NOT RECALL ASSOCIATED WITH MY VIN NUMBER. I BELIEVE MY VIN NUMBER WAS LEFT OUT IN ERROR AND THIS SHOULD BE RECALLED. THIS VEHICLE HAS ALSO LOST POWER A NUMBER OF TIMES WHILE DRIVING, BUT THOSE INCIDENTS DIDN'T RESULT IN AN ACCIDENT (LUCKILY). THANK YOU. *TR

THE EXHAUST MANIFOLDS ARE DEFECTIVE WHICH CREATES NOISE AND ALLOWS FUMES TO ESCAPE. INFINITI ADMITS THEY ARE DEFECTIVE BUT THEY WANT $2,800 TO $4,000 TO REPLACE THEM. THIS SHOULD BE CONSIDERED A SAFETY HAZARD AND INFINITI SHOULD REPLACE THEM FREE OF CHARGE. *TR
