2011 Nissan Sentra

THE VEHICLE SUDDENLY AND UNEXPECTEDLY HESITATES LOSES POWER AND STALLS. I HAVE BEEN TOLD BY TWO INDEPENDENT NISSAN REPAIR SHOPS THAT THE ECM NEEDS TO BE REPROGRAMMED AND UPDATED TO THE NEWEST VERSION. BECAUSE OTHER COMPONENTS THAT ARE TIED IN TOGETHER IS CAUSING THE CHECK ENGINE LIGHT TO COME ON. AP0101 DIAGNOSTIC CODE STATES THAT THE MAF SENSOR IS BAD. THE MAF SENSOR HAS BEEN REPLACED, THE GAS TANK CAP HAS BEEN REPLACED WITH AN OEM, ETC. I BELIEVE THAT THE ECM IS NOT COMMUNICATING CORRECTLY WITH THE MAF SENSOR SIGNAL AND IS WHAT IS CAUSING THE ENGINE TO STALL UNEXPECTEDLY. THIS HAS HAPPENED THREE TIME AND I CAN HAVE AN ACCIDENT DUE TO THE ENGINE STTALLING WITHOUT ANY WARNING. I CAN BE SEVERELY REAR ENDED IN THE FREEWAY.

WHEN DRIVING THE CAR SOMETIMES THE VDC LIGHT COMES ON AND THE CAR WILL NOT GO. IT ACTS LIKE IT WILL NOT TAKE THE GAS AND IT DOES NOT WANT TO GO. WE HAVE TRIED TO CUT THE SWITCH OFF BUT COULD NOT. WE HAD TO CUT THE CAR OFF AND LET IT SET FOR A FEW MINUTES AND THEN START IT BACK UP AND IT WOULD BE FINE. IT HAS HAPPENED A COUPLE OF TIMES AND ITS A REALLY SCARY FEELING WHEN YOUR DRIVING DOWN THE ROAD AND IT HAPPENS. I WOULD LIKE TO KNOW WHAT CAN BE DONE ABOUT THIS AND WHAT THE PROBLEM MIGHT BE

WHEN DRIVING FROM A STOP POSITION THE CAR WILL APPEAR TO HESITATE UPON ACCELERATION. SOME HESITATIONS ARE LONGER THAN OTHERS. IT'S SCARY AS IF THE CAR DOESN'T WANT TO MOVE BUT AS OF YET WILL THEN GO.NOT SURE OF THE PROBLEM COMPONENTS RELATED TO THE HESITATION. IT IS INTERMITTENT AS THIS TIME AND NEW TO MY POSSESSION OF THE CAR. I FEAR THE CAR WILL AT SOME POINT NOT GO WHEN PRESSING ON THE GAS. SCARY.

I PURCHASED THE CAR MARCH 14, 2011 AND THE VEHICLE HAS HAD ISSUES WITH MAKING NOISES AND VIBRATING. I RETURN THE VEHICLE THE FOLLOWING WEEK AND DEALERSHIP COULD FIND NO PROBLEMS, BUT REFERRED TO NISSAN SERVICE. ON JULY 29, 2011, MY MOTHER MOVED MY CAR OUT OF A FIRE LINE AT APPROXIMATELY 20-25 MPH. THE GAS PEDAL WENT WAY TO THE FLOOR AND SHE ATTEMPTED TO DEPRESS THE BRAKES. AT THAT TIME THE PEDAL TRAVELED MORE THAN 3/4 TO THE FLOOR ALMOST INSTANTLY. SHE DID LOSE CONTROL OF THE VEHICLE AND CRUSHED INTO A TREE TO STOP THE CAR. SHE NEVER REGAINED THE USE OF THE BRAKES. I DID GO TO THE TOWNG COMPANY AND TOOK PICTURE WHERE THE GAS PEDAL IS STILL IN 3/4 INCH FROM THE FLOOR. DJ

I HAVE THE INTELLIGENT KEY SYSTEM WITH THIS CAR. I WAS TOLD WHEN I PURCHASED THIS CAR THAT IN ORDER TO START THE CAR, MY FOOT MUST BE ON THE BRAKE. YOU CAN PUT THE CAR IN AUXILIARY MODE WITH THE FOOT OFF THE BRAKE BUT IN ORDER TO START THE CAR THE FOOT MUST BE ON THE BRAKE. I DISCOVERED THAT I WAS ABLE TO START MY CAR WITH MY FOOT OFF THE BRAKE. I TOOK THE CAR IN FOR SERVICE TO DEALER THAT I PURCHASED THE CAR FROM. I WAS SUBSEQUENTLY TOLD THAT WITH MY MODEL CAR I COULD START THE CAR WITH MY FOOT OFF THE BRAKE. I CALLED NISSAN SINCE I WAS GETTING CONFLICTING INFORMATION AND THEY INFORMED ME THAT IN FACT I SHOULD NOT BE ABLE TO START MY CAR IN THIS MANNER. THEY CREATED A FILE REGARDING THIS PROBLEM, FILE #7139963, THEN I WAS TOLD THAT I SHOULD TAKE MY CAR IN TO ANOTHER DEALER AND HAVE THEM LOOK AT THIS PROBLEM. I'M NOT SURE IF OTHER SENTRA OWNERS ARE HAVING THIS PROBLEM ALSO OR WHETHER OR NOT THIS COULD BECOME A SAFETY ISSUE (WHICH I WOULD THINK IT COULD BE, ESPECIALLY IF A YOUNG CHILD WAS SOMEHOW ABLE TO START THE CAR AND PUT IT IN GEAR) BUT I FIGURED THIS SHOULD BE ON RECORD SINCE ALL NISSAN SUGGESTED WAS THAT I TAKE IT TO ANOTHER DEALER.

THE VEHICLE HAS HAD ISSUES WITH ABS ACTUATOR MAKING NOISES AND VIBRATING. DEALERSHIP COULD FIND NO PROBLEMS, BUT REFERRED TO NISSAN SERVICE BULLETIN. ON FEBRUARY 2, 2011, I WAS TRAVELING AT APPROXIMATELY 20-25 MPH. AS I APPROACHED A RED LIGHT I ATTEMPTED TO DEPRESS MY BRAKES. AT THAT TIME THE PEDAL TRAVELED MORE THAN 3/4 OF THE WAY TO THE FLOOR ALMOST INSTANTLY. THERE WAS A LOUD METALLIC CLANKING AND GRINDING SOUND AND A VERY STRONG VIBRATION COMING FROM UNDER BRAKE PEDAL. I ALMOST LOST CONTROL OF MY VEHICLE AS IT PULLED TO THE LEFT AND ALMOST TRAVELED INTO THE ONCOMING LANE. AFTER 2-3 SECONDS I REGAINED THE USE OF MY BRAKES. *LN
