2007 INFINITI G35 Engine And Engine Cooling Problems

CHECK ENGINE LIGHT CAME AND MECHANIC CANNOT FIGURE OUT WHY. *TR

TL* THE CONTACT OWNS A 2007 INFINITI G35. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 40 MPH, THE ENGINE STALLED WITHOUT WARNING. THE VEHICLE WAS ABLE TO RESTART AFTER MULTIPLE ATTEMPTS. THE VEHICLE WAS TAKEN TO THE DEALER, WHO RECOMMENDED REPROGRAMMING THE ECM AND THE TCM SYSTEM. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN: 03V455000 (ENGINE AND ENGINE COOLING). THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

I OWN A 2007 INFINITI G35 SEDAN. THE VEHICLE HESITATES/STUTTERS/SURGES WHEN SLOWLY ACCELERATING FROM A STOP. THIS MAINLY OCCURS WHEN THE ENGINE IS COLD (AFTER A COLD SOAK). THE FAILURE OCCURS WHILE TURNING OR DRIVING FORWARD AND WAS NOTICED AT 5-30 MPH AND RPMS ARE BETWEEN 700-1800. THE VEHICLE WAS TAKEN TO THE DEALER ON NUMEROUS OCCASIONS AND THEY "COULD NOT DUPLICATE FAILURE." THIS IS DANGEROUS AS THE VEHICLE ENGINE SURGE COULD CAUSE A COLLISION. *TR

THE VEHICLES ENGINE CONSUMES OIL DURING NORMAL OPERATION AT AN UNACCEPTABLE RATE. I NEED TO ADD OIL AFTER EVERY 300-500 MILES! AND I USUALLY END OF ADDING UP TO 3- 4 QUARTS OF EXTRA OIL BETWEEN OIL CHANGES. THE LEVEL OF CONSUMPTION MAY DIFFER FROM VEHICLE TO VEHICLE BUT NEVERTHELESS, IT IS EXCESSIVE. IF I WERE NOT TO DO SO, THE ENGINE WOULD RUN OUT OF ALL OIL WELL BEFORE THE RECOMMENDED OIL CHANGE INTERVAL AND RESULT IN CATASTROPHIC FAILURE. THIS PROBLEM REQUIRES ME TO PULL OVER SEVERAL TIMES AT THE SIDE OF THE ROAD TO ADD OIL DURING NORMAL OPERATION. SUCH MANEUVERS ON A JOURNEY ARE HAZARDOUS AND RISKY (I.E. TRAFFIC DISRUPTION, POSSIBLE CRASH). MOREOVER, IF A CATASTROPHIC ENGINE FAILURE IS TO RESULT BECAUSE OF THE DEFECT WHILE THE VEHICLE IS IN OPERATION, IT CAN RESULT IN SERIOUS INJURIES OF OCCUPANTS (I.E. FIRE HAZARD, CRASH) AND A HIGH RISK...

I BOUGHT MY SON A NISSAN INFINITI G35 S MAKE 2007. WHEN DRIVING, ALL OF A SUDDEN HE NOTICED BATTERY LIGHT ON, BRAKE LIGHT ON AND POWER STEERING QUIT WORKING. TURNING THE STEER WAS EXTREMELY HARD, MUCH MUCH HARDER THAN A NONPOWER STEERING. FORTUNATELY HE HAS STRONG HANDS AND IS USED TO DRIVING AN OLD NONPOWER STEERING VEHICLE, HENCE HE WAS ABLE TO STILL DRIVE IT. MOST ELDERLY, OR FEMALES WOULD END UP WITH AN ACCIDENT,WHEN AT HIGH SPEED, THEY CAN NOT TURN THE STEERING WHEEL. ESPECIALLY IF IT HAPPENS WITHOUT ANY WARNING AT HIGH SPEED. I TOOK IT TO DEALER. FOUND DRIVE BELT TENSIONER OUT OF ALIGNMENT WITH PULLEYS. DRIVE BELT COMING APART.DEALER REPLACED DRIVE BELT AND DRIVE BELT TENSIONER FOR FREE. WITHIN WARRANTY TIME. BUT I THINK IT IS A SAFETY HAZARD IF IT HAPPENS AGAIN TO HIM OR ANYBODY. HENCE I AM NOTIFYING YOUR AGENCY SO YOU...
