2012 Infiniti M37

The contact owns a 2012 Infiniti M37. The contact stated that while driving at various speeds, the vehicle hesitated upon depressing the accelerator pedal without warning. The contact also stated that while driving on an incline, the vehicle lost power upon depressing the accelerator pedal and rolled backward, forcing the contact to depress the accelerator pedal to the floorboard to maintain momentum and resume driving. Upon investigation, the contact associated the failure with the Intelligent Power Distribution Module (IPDM) relay. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 140,000.

I NOTICE WHEN I BROUGHT THIS CAR AT 47,000 MILES USED THE CAR WAS LACK OF POWER AND HESITATED TO GO WHEN TRYING TO PASS OTHER CAR ..I THOUGHT IT WAS JUST SOFTWARE PROBLEMS BUT IT HAPPENED THE 2ND TIME , BUT THIS TIME ALMOST COST THE ACCIDENT,WHEN I WAS GOING TO MAKE A LEFT TURN THE HESITATED FOR ABOUT 6TO9SECOND DELAY BEFOR IT TAKE OFF WAS CLOSE OF OTHER CAR HITTING ME

TOTAL LACK OF ACCELERATION WHEN PASSING. THERE IS A 2-3 SECOND DELAY PRIOR TO THE DOWNSHIFT AND I'M NEVER SURE WHEN THE ACCELERATION WILL TAKE PLACE. THIS PROBLEM OCCURS FROM 50MPH AND UP. I HAVE HAD THIS PROBLEM SINCE I PURCHASED THE CAR AND IT HAS NOT CHANGED OVER TIME. INFINITY REPROGRAMMED THE ECM AND NO IMPROVEMENT WAS NOTED. I GAVE UP ON THEIR SERVICE SUPPORT. THANKS

HAVE OWNED THE CAR SLIGHTLY OVER A YEAR. SINCE THE BEGINNING THE TRANSMISSION HAS SHIFTED ERRATICALLY, IS IN 4TH GEAR AT 25 MPH. WHEN STEPPING ON GAS THE CAR HESITATES WHILE TRYING TO PICK A GEAR. THERE IS NO POWER AT LOW SPEEDS BECAUSE THE CAR IS IN TOO HIGH A GEAR. AT HIGHER SPEEDS IF YOU TOUCH THE BRAKES THE CAR DROPS TWO OR THREE GEARS CAUSING THE CAR TO SHAKE VIOLENTLY FROM THE DOWNSHIFT. THE ENGINE KNOCKS CONSTANTLY AT LOW SPEEDS DUE TO THE GEARING EVEN THOUGH PREMIUM FUEL IS REQUIRED. DEALER HAS TRIED TO REPAIR AND APPLIED SOFTWARE PATCH THAT TOOK ALMOST A YEAR TO RECEIVE BUT NO HELP. DEALERSHIP SAYS NOTHING CAN BE DONE. FROM RESEARCH AND OTHER NHTSA COMPLAINTS THIS IS A COMMON PROBLEM. TRIED TO GET INFINITI TO REPURCHASE BUT THEY REFUSE TO STAND BEHIND CAR, SAY IT'S "WITHIN SPECS". CAR IS UNSAFE BECAUSE OF SEVERE DOWNSHIFT COMPRESSION AT HIGHER SPEED, NO POWER AND SEVERE HESITATION AT LOWER SPEEDS. *TR

TL* THE CONTACT OWNS A 2012 INFINITI M37. THE CONTACT STATED THAT THE TRANSMISSION HESITATED AND EXHIBITED A LOUD BANG WHEN SHIFTING. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND THE VEHICLE WAS TEST DRIVEN. THE DEALER RE-PROGRAMMED THE TRANSMISSION CONTROL MODULE AND THE ENGINE CONTROL MODULE. THE CONTACT STATED THAT THE VEHICLE PERFORMED WELL FOR A WHILE BUT THE FAILURE SOON RECURRED. THE VEHICLE HAD NOT BEEN TAKEN BACK TO THE DEALER. THE CONTACT SPOKE WITH THE MANUFACTURER AND WAS TOLD THAT THERE WAS A DESIGN FLAW WITHIN THE VEHICLE BUT A REMEDY WAS NOT YET AVAILABLE. THE FAILURE MILEAGE WAS 7,473 AND THE CURRENT MILEAGE WAS UNKNOWN.

EXPERIENCED VERY SLOW ACCELERATOR RESPONSE SINCE VEHICLE WAS BRAND NEW. NOW IN ADDITION TO THAT THE CAR IS HAVING HORRIBLE PROBLEMS WHILE BRAKING, TRANSMISSION BANGS OUT OF GEAR, THE CAR ALSO DROPS MULTIPLE GEARS AT ONCE WHICH CAUSES A VERY HIGH REV OF ENGINE. IT FEELS SO ROUGH IT MAKES IT FEEL LIKE YOU'VE BEEN HIT FROM BEHIND. THIS CAR FEELS VERY UNSAFE TO DRIVE. THERE MUST BE FAULTY TRANSMISSIONS OR SOFTWARE HERE. *TR
