NHTSA Complaint #10896884 — 2012 NISSAN ALTIMA

8/12/16 I WAS DRIVING FROM SCHAUMBURG IL. TO LA CROSSE WI WITH MY DAUGHTER IN MY CAR AND MY SON FOLLOWING BEHIND. DRIVE IS APPROX 3 HRS & 50 MINS. THE WEATHER OUTSIDE HIGH 80'S & HUMID. AN HOUR INTO MY TRIP ON 90WEST IN STOP AND GO TRAFFIC ON THE EXPRESSWAY DUE TO CONSTRUCTION. WENT TO ACCELERATE FROM A COMPLETE STOP THE CAR WOULD ONLY GO TO 20 MPH WITH MY FOOT TO THE FLOOR & IT TOOK SOME TIME. THE RPMS DIDNT MOVE, THE CAR DIDNT REV, THERE WERE NO WARNING LIGHTS, NO LIGHTS DIMMING ON THE INTERIOR & THE TEMPERATURE GAUGE WAS JUST WHERE IT SHOULD BE. I THOUGHT IT WAS JUST A FLUKE. WHEN APPROACHING THE WI DELLS 2 HOURS INTO MY TRIP & AN HOUR & A HALF REMAINING, I WAS IN THE "FAST LANE" OF TRAFFIC DOING ABOUT 80 MPH, I WENT TO ACCELERATE MORE I NOTICED THE SAME THING WAS HAPPENING. ONLY NOW MY SPEED WAS RAPIDLY DECREASING. I MOVED OVER & GOT OFF ON THE NEAREST EXIT STILL ATTEMPTING TO ACCELERATE, I PULLED INTO A GAS STATION. HESITANT ON SHUTTING THE CAR OFF NOT KNOWING WHAT WAS HAPPENING. CALLED MY BROTHER & DESCRIBED THE EVENT I HAD EXPERIENCED. ADVISED TO SHUT IT DOWN THINKING MAYBE THE SYSTEM JUST NEEDED A RESET. WAITED 20 MINS & ADVISED MY SON THAT WE WOULD STAY IN THE "SLOW" LANE. CAR STARTED RIGHT UP & WENT THE HOUR & 30 MINS WITH NO PROBLEM. CAR SAT AT THE HOTEL WE WERE STAYING AT ALL NIGHT. MORNING OF THE 13TH DID SHORT TRIPS, GOT LUNCH & ATTEND A MEETING NEAR CAMPUS. CAR WAS JUST AS IT ALWAYS HAS BEEN. 4 PM CST I GOT ON 90E TO HEAD HOME. THE SAME 3HR 50 MIN 248 MILE TRIP. OUTSIDE MID 80'S NOT AS HUMID AS THE DAY BEFORE. 1 HR & 30 MIN FROM MY HOME DOING 80/85 MPH, NOW IN VARIOUS CONSTRUCTION AREAS THAT DO NOT PROVIDE A SHOULDER, MY CAR STARTS TO LOSE ACCELERATION WHILE I AM TRYING TO ACCELERATE. I'M IN THE "FAST" LANE & NOONE WOULD MOVE OVER.LET IT SIT 10 MINUTES DROVE THE LAST HOUR & A HALF, NO PROBLEMS.
