2012 NISSAN SENTRA Fuelpropulsion System Problems

When driving at 70 or above mph for a long distances, speed automatically declines to 60 mph and will not increase. When trying to accelerate, nothing happens. After a few miles, my vehicle then starts to accelerate on its own. The problem is extremely unsafe and frightening, especially with express highway traveling. Ive traveled out of state and the past 6 months when I've moticed this now frequent problem. I informed my mechanic who said it could be my transmission or possibly fuel pump, which are not his areas. He advised talk to NISSAN and stated Nissan is known for faultly transmission s on Sentras. Mines is a 2012 with only 126k of mileage. Was was there no recalls on this? I will now see what Dealer has to say. What can be done to hold Nissan responsible? I 've screenshot an article regarding many complaints on this. Now my...

WHILE DRIVING FROM AZ TO CA ON THE HIGHWAY, MY VEHICLE LOST THE ABILITY TO SPEED UP WHILE PUSHING THE PEDAL. IT HAPPENED A TOTAL OF THREE TIMES ON 2 DIFFERENT DAYS.THE FIRST TWO TIMES I COULDN'T GET ABOVE 60 HOWEVER ON ONE OCCASION, IT DROPPED DOWN TO 3-5 MILES PER HOUR AND THE PEDAL WAS TO THE FLOOR. I WAS ON A 2 LANE HIGHWAY WITH SEMI TRUCKS HAVING TO PASS ME ON THE LEFT. I WAS TERRIFIED, HAD NO CELL SERVICE AND HAD TO DRIVE ON THE SHOULDER WITH MY HAZARDS ON UNTIL THE SHOULDER DISAPPEARED. EVENTUALLY IT RETURNED TO NORMAL, BUT IT WAS A VERY SCARY EXPERIENCE. I SEE NOW THAT NISSAN HAS HAD A MULTITUDE OF COMPLAINTS WITH THE SAME PROBLEM. SHAME ON YOU FOR NOT RECALLING THE TRANSMISSION. *TR

WHILE DRIVING ON THE HIGHWAY, THE CAR WILL STOP RESPONDING TO THE GAS PEDAL AND LOSE POWER. YOU WILL EITHER HAVE TO PULL OVER OR MAINTAIN A MUCH SLOWER SPEED. THIS BECOMES A HAZARD AND CAN CAUSE AN ACCIDENT.

I AM HAVING ISSUES WITH THE TRANSMISSION. IT APPEARS THAT THE ENGINE IS NOT CHANGING GEARS AUTOMATICALLY. OR IT COULD BE A PROBLEM WITH THE FUEL INJECTION OF THE VEHICLE. ALSO THERE IS A PROBLEM WITH THE AIRBAGS DEPLOYMENT SYSTEM.

CAR IS HESITANT, LOSING POWER AT HIGHWAY SPEEDS. AFRAID OF GETTING REAR ENDED ON HIGHWAY!! SOMETIMES IT HAPPENS AT A STOP.

I PURCHASED MY SENTRA NEW IN MARCH 2012. AT THAT TIME, MY GAS MILEAGE WAS NORMAL, AND AS ADVERTISED. WITHIN THE YEAR, I WENT FROM 30MPG AVERAGE TO 27. EVERY YEAR SINCE THEN, IT HAS GRADUALLY GOTTEN WORSE, AND I AM NOW DOWN TO 23MPG, REGARDLESS OF THE TYPE OR GRADE OF GAS I USE. IT'S ACTUALLY WORSE WITH PREMIUM GAS. I HAVE DONE ALL MAINTENANCE ON THE CAR ON TIME, REGULAR OIL CHANGES, ETC. I'VE COMPLAINED TO THE DEALERSHIP MULTIPLE TIMES, AND THEY CLAIM TO FIND NO PROBLEMS WITH IT.

WAS DRIVING ON FREEWAY, ACCELERATING TOWARD 70 MPH. ACCELERATOR DROPPED AWAY FROM UNDER MY FOOT, TACHOMETER "PEGGED" 5000 RPM. QUICK SCAN OF INSTRUMENT PANEL SHOWED CAR WAS NOW IN NEUTRAL, NOT DRIVE. MY HANDS WERE BOTH ON THE STEERING WHEEL; I DIDN'T TOUCH THE GEARSHIFT LEVER. THE CAR SHIFTED ON ITS OWN. THIS STARTED A SERIES OF PROBLEMS WITH THE TRANSMISSION THAT CONTINUE TO ESCALATE; TRANSMISSION WILL OVERRIDE BRAKING (CAUSED 2 ACCIDENTS 2 WEEKS APART); ON A 500-MILE (1-WAY) BUSINESS TRIP IN JULY, CAR WENT INTO FAIL-SAFE MODE 3 TIMES - LOSS OF POWER, ACCELERATOR NON-FUNCTIONAL. CAR TAKEN OFF THE ROAD BY NISSAN CORP, BUT NO REPAIRS DONE; AFTER 49 DAYS OUT OF SERVICE, CAR WAS RELEASED TO ME, CONTINUES TO EXHIBIT TRANSMISSION PROBLEMS. NOW THE STEERING IS EXTREMELY HARD TO OPERATE, AS IF THERE'S NO POWER STEERING IN THE CAR. WHEN TRANSMISSION OVERRIDES BRAKES, IT FEELS LIKE THE CAR...
