2010 Nissan Altima

At some point on the highway the car throttles down to less than 60 mph. Mashing the gas pedal to the floor results in nothing happening. This causes a dangerous road situation with the slower speed, but the worst part is when it suddenly begins to accelerate again, potentially hitting the car in front of you unexpectedly. No mechanic can reproduce the effect as it only takes place after driving on the highway for an hour or so.

Was driving home on a rather busy highway, had my cruise control set at 65 mph, then the cruise control just shut off, no warning indications, no alerts, just poof off. It caused my car to lose speed instantly and caused a great deal of concern for both myself and everyone around me, this is now the second time this has happened within a month. Have not had time to take it to a dealership yet going to do so next week and see if they cant figure it out.

AFTER BUYING THE CAR IN LATE 2019, IT CAME TO MY ATTENTION THAT THE CVT TRANSMISSION WAS FAULTY. I LATER FOUND THAT THE YEAR, MODEL, AND MAKE OF MY VEHICLE WAS INCLUDED IN A RECALL OF THE CVT TRANSMISSIONS, AMONG OTHER SAFTEY ISSUES. AFTER HAVING THE VEHICLE INSPECTED BY THREE DIFFERENT SHOPS, THE CONCLUSION WAS MADE THAT IT WAS INDEED THE CVT TRANSMISSION AND STEPPER MOTOR CAUSING THE PROBLEMS. UPON FURTHER EXAMINATION, IT WAS FOUND THAT MY VEHICLE HAS NOT HAD A RECALL REPLACEMENT OF THE FAULTY PARTS AS OF YET. THE CAR HAS ONLY 96K MILES ON IT. WHEN THE ISSUE ARISES, THE TRANSMISSION GOES INTO A "SAFE" MODE. THIS MODE CREATES A THROTTLE PROBLEM AS THE VEHICLE CANNOT TRAVEL FASTER THAN 40 MPH WITHOUT A HIGH PITCH WIND UP SOUND AND A CUT IN POWER OF ALMOST 50%.

WHEN ACCELERATING FROM 20MPH TO 40MPH THE RPMS INCREASE TO 3RPM AND THE TRANSMISSION HESITATES TO CHANGE THE GEAR. IT SEEMS TO BE AN ISSUE WITH THE TCM (TRANSMISSION CONTROL MODULE). I BOUGHT MY CAR BRAND NEW IN 2010. IT HAS 220,000 MILES ON IT. I DID SOME RESEARCH ONLINE AND SAW THIS US A KNOWN ISSUE WITH THE CAR. NISSAN ALSO SENT OUT A BULLETIN NTB10-121B. THEY SHOULD RECALL THESE CARS AND FIX THE ISSUE AT THEIR COST. ATTACHED IS THE PDF OF THE BULLETIN.

AFTER APPROXIMATELY 2 HOURS OF CONTINUOUS DRIVING THE VEHICLE REFUSES TO ACCELERATE. WHATEVER SPEED YOU ARE DRIVING AT THE TIME THE ISSUE KICKS IN IS THE MAXIMUM SPEED THE VEHICLE WILL DRIVE. STOPPING AND TURNING OFF THE VEHICLE SEEMS TO RESET THE PROCESS AND YOU CAN DRIVE NORMALLY FOR THE NEXT 15 - 30 MINUTES UNTIL THE PROBLEM RESURFACES. LOOKING ONLINE INDICATES THIS A COMMON ISSUE FOR NISSAN VEHICLES MANUFACTURED FROM 2007 - 2010. THE ISSUES SEEMS TO SURFACE ONCE THE VEHICLES HIT 80,000 MILES. THIS IS A SAFETY HAZARD AS IN MY CASE IT PREVENTED ME FROM DIVING AT THE POSTED SPEED LIMIT WHILE ON A MAJOR HIGHWAY.

THIS IS A HUGE SAFETY DEFECT. I WAS DRIVING ON THE HIGHWAY, GOING ABOUT 65/70 MPH. I HAD TO BREAK, DUE TO TRAFFIC. I PRESSED ON THE GAS, IT WENT ALL THE WAY TO THE GROUND, THE CAR DIDN'T ACCELERATE AT ALL. I RELEASED THE GAS AND PRESSED AGAIN...STILL THE SAME THING. THIS IS IN THE MIDDLE OF VERY FAST MOVING TRAFFIC. I HAD TO PUT MY HAZARDS ON, AS THE CAR CONTINUED TO SLOW DOWN... THEN SUDDENLY AS I WAS RELEASING MY FOOT FROM THE GAS...IT FORCEFULLY ACCELERATED CAUSING ME TO SLAM ON THE BREAKS, TO KEEP ME FROM HITTING THE CAR IN FROM OF ME. I HAD TO CAREFULLY COAST MY WAY TO THE RIGHT SIDE OF THE ROAD, AS I WAS IN THE FAST LANE CLOSEST TO THE MEDIAN. IT STILL WOULDN'T COMPLETELY ACCELERATE, IT KIND OF SCOOTED OVER THE SIDE OF THE ROAD. I TURNED THE CAR OFF, WAITED FOR ABOUT 2 MINUTES AND ATTEMPTED TO START THE CAR AND IT WOULD NOT START. AFTER ABOUT 3 TRIES IT STARTED, AND I COULD DRIVE THE CAR BACK TO MY HOUSE, AND THE CAR CONTINUED TO REPLICATE THE SAME ISSUE. I HAVEN'T DRIVEN THE CAR SINCE. IT'S SITTING IN MY DRIVEWAY. I'M AFRAID TO DRIVE IT, AND AT THE PRESENT MOMENT, DON'T HAVE THE MEANS TO GET IT TOWED ANYWHERE TO BE LOOKED AT. IT'S SUCH A SHAME THAT AS SOON AS YOU PAY A CAR OFF, AND YOU ARE NO LONGER COVERED UNDER THE WARRANTY, THAT YOU START TO HAVE MAJOR PROBLEMS. I BOUGHT A NISSAN, BECAUSE THEY WERE KNOWN FOR THEIR LONGEVITY.... I WILL NEVER BUY NISSAN AGAIN. I LOOK ON THE SITES TO SEE IF THERE IS A RECALL FOR THIS ISSUE, AND HAVE NOT FOUND ONE. PLEASE SOMEONE HELP ME. I'M A SINGLE MOM, WITH TWO KIDS. ONE IN HIGH SCHOOL AND THE OTHER IN COLLEGE. I CAN'T AFFORD ANOTHER CAR NOTE.
