2008 INFINITI G37 Engine And Engine Cooling Problems

THIS HAS BEEN HAPPENING ON MULTIPLE OCCASIONS. WHENEVER I AM DRIVING AND I TRY TO STOP, SOMETIMES THE ENGINE INCREASES WHILE BRAKING. IT HAS HAPPENED ABOUT 4 TIMES NEAR A STOP SIGN WHEN I AM DRIVING 20MPH, AND IN THE HIGHWAY DRIVING 55-60MPH. THIS IS A SERIOUS ISSUE AND CAN CAUSE AN ACCIDENT. I AM TAKING IT TO THE DEALERSHIP ON WEDNESDAY SO THEY CAN EITHER ISSUE A LEMON OR FIX THE ISSUE. I AM VERY UNHAPPY WITH THIS PROBLEM. I SEARCHED ONLINE AND SOME PEOPLE HAVE BEEN HAVING THE SAME ISSUE AND DEALERS TELLING THEM "THERE IS NOTHING WRONG". *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
