2003 Infiniti I35 engine problems

“Camshaft sensor according to the Infiniti dealership (Ray Brandt on Causeway in Metairie La.) Is malfunctioning at makes the car engine die while driving. Then when you restart the car the engine revs fine in neutral but once in drive it won't go over 5 mph. Also the timing chain tensioner fails on this car and can cause severe engine damage while the car is being driven. I've looked up both of these problems and have spoken with Nissan and Infiniti and a simple internet search will also confirm that these 2 problems are extremely common on this 5th generation engine. Nissan even lost 2 class action lawsuits on the timing tensioner. Well if Nissan lost 2 court battles over an engine defect that every Nissan internet forum says is a very very common problem then why isn't there a recall. And shouldn't hazing headlights be a safety issue on ALL cars? Almost all cars have this problem and manufacturers keep building cars with UNSAFE headlights. Why aren't these recalls? Thank you for this website. As an American Citizen and consumer with a daughter these safety concerns are very troubling to me and all my friends and business associates.”

“2003 INFINITY I35 STALLS/DIES WITHOUT WARNING, SPITS/JERKS FORWARD, CHECK ENGINE LIGHT, TCS AND SLIP. HAPPENS WHILE DRIVING BUT USUALLY STARTS RIGHT BACK UP AFTERWARDS. HAS HAPPENED A NUMBER OF TIMES HAVE REPLACED ONE CAMSHAFT POSITION SENSOR AND STILL HAVE THE SAME ISSUE.”

“TL* THE CONTACT OWN A 2003 INFINITI I35. THE CONTACT STATED WHILE DRIVING 45 MPH, THE VEHCILE DECELERATED, LOSS MOTIVE POWER, AND STALLED WITH AN UNKNOWN WARNING LIGHT ILLUMINATED.

THE CONTACT WAS NOTIFIED OF A CAMSHAFT CYLINDER MISFIRE. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 117,440.”

“MY 2003 INFINITY I35 STALSL WHILE DRIVING ON LOCAL ROADS AND BUSY STATE HIGHWAYS LOCATED IN THE GREATER HILTON HEAD SC AREA. IT REQUIRES COASTING TO THE SIDE OF THE ROAD, TURNING THE VEHICLE OFF. THE SERVICE ENGINE LIGHT TURNS ON. I THEN CAN RESTART THE ENGINE AND RETURN TO MY HOME AS SOON AS I CAN. I RESEARCHED THE PROBLEM AND FOUND A RECALL NOTICE THAT DESCRIBED MY PROBLEM. SINCE DISCOVERING THE PROBLEM, I TOOK IT TO THE DEALER AND THEY INFORMED ME THAT MY VEHICLE WAS NOT COVERED BY THE RECALL. I HAVE TAKEN IT BACK TO THEM TWICE NOW TO FIX THIS PROBLEM AT MY EXPENSE. THE PROBLEM HAS AGAIN RETURNED AND I DON'T WANT TO PAY A 3RD REPAIR BILL TO FIX A PROBLEM THAT OTHERS ARE GETTING FIXED UNDER THE RECALL ( 03V455000). THIS IS GETTING EXPENSIVE, VERY DANGEROUS, AND ELIMINATES THE USE OF MY CAR BY MY WIFE. SHE IS AFRAID TO DRIVE IT AND I UNDERSTAND HER FEAR. WHAT ADDITIONAL INFORMATION IS NEEDED TO GET THIS PROBLEM TAKEN CARE OF.”

“CAR SHUTS DOWN. OVER THREE YEARS AGO IT DIED WHILE DRIVING. I TOOK IT TO THE INFINITY DEALERSHIP. THEY TOLD ME IT WAS CAM SENSOR. HAD IT & CRANK SENSOR REPLACED. PROBLEM PERSISTED. TOOK BACK TO INFINITY & WAS TOLD IT WAS THE CYLYNOID. HAD THATBREPLACE. PROBLEM PERSISTED. THE INFINITI DEALER SAID THE TIMING CHAIN NEED REPLACED BUT MY CAR WAS NOT WORTH SPENDING THAT AMOUNT OF REPAIR. MY CAR IS WELL KEPT WITH IT JUST NOW TIRNING OVER 100,000 MILES. I GOT A SECOND OPINION FROM A CERTIFIED CUSTOM NISSAN/INFINITI SHOP. HE LAUGHED AT THE TIMING CHAIN SUGGESTION. THEY HAVE BUILT & REPAIRED THOUSANDS OF MY VEHICLE & OTHERS WITJ TIMING CHAINS ...CHAINS DO NOT HAVE ISSUES ON CARS WITH VERY LITTLE MILAGE & GRANDMA DRIVING STYLE!. THEY CHANGED THE SENSORS FOR ME AGAIN USING ORIGINAL INFINITI PARTS. MY CAR RAN FINE FOR 2 YEARS. NOW I FACE THE SAME PROBLEM ONCE MORE. UNFORTUNATELY BEYOND RECALL LIMIT THAT I AM CERTAIN THE DEALERSHIP KNEW ABOUT 3 YEARS AGO WHICH WOULD HAVE BEEN WITHIN RECALL CORRECTION TIME LIMITS! MY CAR LOOSES ALL POWER & ALL DASH LIGHTS COME ON (ENGINE, TCS, SLIP,BRAKE, ETC). SOETIMES IT WILL INSTANTLY COME BACK ALIVE. MOST TIMES IT IS JUST DEAD. SCENARIOS…”
