Open the full vehicle complaint log (all categories)THE VEHICLE HAS STARTED TO STUTTER UPON TAKING OFF AND SHOWS SIGNS OF POWER LOSS. AFTER MUCH INVESTIGATION, THESE G37S HAVE A MINOR DEFECT THAT CAUSES THE ENGINES TO RUN ON LOW OIL PRESSURE. THE PART 'GALLERY GASKET' IS THE CULPRIT THAT CAUSES THESE ENGINES TO, IN BAD CASES, LAST ONLY UP TO 100K MILES. EVERYWHERE ONLINE THERE ARE INFINITI OWNERS TALKING ABOUT THIS GALLERY GASKET PROBLEM AND FEW OF THEM HAVE HAD TO BUY A REPLACEMENT ENGINE BECAUSE OF IT. INFINITI HAS FAILED TO COME FORWARD WITH A SOLUTION TO REDUCE THE AMOUNT OF OIL RELATED PROBLEMS IN THESE CARS. AS MENTIONED, THIS IS A MINOR DEFECT WITH THE VQ37 ENGINES BUT WITH AN OUTCOME THAT CAN COST THOUSANDS OF DOLLARS TO EITHER FIX OR REPLACE. A SIMPLE GOOGLE SEARCH OF 'G37 GALLERY GASKET' WILL BRING MANY PAGES OF OWNERS WITH THE EXACT SAME PROBLEM TRYING TO GIVE EACH OTHER ADVICE. THERE ARE MANY VIDEOS ONLINE SHOWING WHAT AN OWNER MUST GO THROUGH IN ORDER TO FIX THEIR DAILY DRIVERS. IT WOULD ONLY BE RIGHT FOR INFINITI TO COME FORWARD AND OFFER AT LEAST FREE LABOR TO FIXING THESE CARS WHEN THE SYMPTOMS FIRST START. THAT WAY OWNERS CAN KEEP DRIVING WITHOUT WORRYING THAT THEIR ENGINES WILL GO OUT DUE TO A BAD GALLERY GASKET. THE G37 IS VERY RELIABLE IN ALL OTHER ASPECTS BESIDES THE GALLERY GASKET. OWNERS CAN ONLY HOPE THAT THE PROPER STEPS ARE TAKEN IN ORDER TO AVOID THE PROBLEMS THE GALLERY GASKET BRINGS.
THE CAR WAS STARTED AND THERE WAS A LOUD RATTLING NOISE COMING FROM THE MUFFLER. IT IS VERY LOUD AND DOESN'T GO AWAY. DID MY RESEARCH AND FOUND OUT THERE IS A DEFECT IN THE MUFFLER PART NUMBER 20100 JL01A. AND CARS THAT EXPERIENCE THIS RATTLING NOISE MUST HAVE THEIR MUFFLERS REPLACE WITH PART NUMBER 20100 JL01C. I WENT TO THE DEALERSHIP AND THEY SAID MUFFLER IS NOT COVERED IN WARRANTY AND THAT THERE IS NO RECALL ON THE DEFECTED PART. THEY WANT TO CHARGE ME $880 TO REPLACE. THE PART IS DEFECTED AND THEY WANT ME TO PAY FOR IT, VERY SCANDALOUS. *TR
THE ENGINE MAKES CLICKING/TAPPING SOUND AT START-UP, DEALER SERVICE DEPARTMENT CONTACTED. I WAS INFORMED THAT I NEED A "SPECIAL" OIL CHANGE, AND THEY'RE AWARE OF THE PROBLEM. AFTER RESEARCHING FOR THE SAME PROBLEM, IT LOOKS LIKE THIS 'SPECIAL' FACTORY OIL WILL BE NEEDED AND COST MORE THAN CONVENTIONAL OIL. HOWEVER, I WAS NOT INFORMED OF THIS SPECIFIC MATTER WHEN THE VEHICLE WAS PURCHASED NOR DOES IT SAY ANYWHERE IN MY OWNER MANUALS. APPARENTLY, ONLY THE DEALERSHIP HAD SUCH OIL AND I AM REQUIRE TO USE IT AFTER THE FACT. *TR
