2010 Nissan Sentra Power Train

ISSUE WITH THE OXYGEN SENSOR. THERE IS A KNOWN ISSUE WITH THE KNOCK SENSOR SENDING WRONG INFORMATION TO THE ECU CAUSING THE ENGINE TO ADJUST TIMING. I'VE GONE THROUGH 3 CATALYTIC CONVERTERS DUE TO THIS ISSUE. NISSAN SAYS THEY'RE UNAWARE OF THE PROBLEM AND KNOW OF NO FIX. GOING THROUGH FORUMS, IT APPEARS THE ONLY WAY TO STOP ENGINE FROM OVER COMPENSATING THE TIMING IS TO ISOLATE THE KNOCK SENSOR FROM THE ENGINE WITH A RUBBER O RING. I HAVE DONE THE REPAIR, BUT CAN ONLY USE PREMIUM FUEL OR RISK CATASTROPHIC ENGINE FAILURE. IT ONLY APPEARS TO HAPPEN TO THE 2007 TO 2012 SE-R SPEC-V (MANUAL TRANSMISSION). I HAVE REPLACED ALL WIRING HARNESSES, ECU, SENSORS AND EVERYTHING ELSE ASSOCIATED WITH THE FUEL SYSTEM. IT TENDS TO HAPPEN AFTER A FEW MINUTES OF TURNING CAR ON. GOES AWAY SOMETIMES AND REAPPEARS SUDDENLY. ENGINE BUCKS AND CONVERTER TURNS BRIGHT RED. HAS BEEN HAPPENING SINCE I BOUGHT THE CAR IN 2018 AND IS RECORDED ONLINE FORUMS AS FAR BACK AS 2008.

TL* THE CONTACT OWNS A 2010 NISSAN SENTRA. AT VARIOUS TIMES, WHILE APPROACHING A STOP, THE VEHICLE WOULD ABRUPTLY SHUT OFF WITHOUT WARNING. THE CONTACT HAD TO PLACE THE VEHICLE INTO PARK AND RESTART THE VEHICLE IN ORDER FOR IT TO OPERATE NORMALLY. THE CONTACT TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC, BUT IT WAS UNABLE TO BE DIAGNOSED. THE CONTACT CALLED BENTON NISSAN OF HOOVER (1640 MONTGOMERY HWY, HOOVER, AL 35216, (205) 938-6103) AND WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN A RECALL. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 80,000.

UNABLE TO DRIVE CAR BECAUSE THE TRANSMISSION GEAR CONTROL WAS LOCKED IN THE P POSITION. THE RELEASE WOULD NOT ALLOW ME TO PLACE THE CAR INTO ANY OTHER GEAR. HAD TO HAVE A NEW GEAR CONTROL ASSEMBLY ORDERED AND REPLACE THE EXISTING ONE. THE CAR WAS ONLY 117,000 MILES ON IT. THE COST FOR PARTS AND LABOR WERE $992 DOLLARS.

I WAS AT A STOP LIGHT AND WHEN IT TURNED GREEN AND I STEPPED ON THE GAS, THE CAR MADE A NOISE AND JERKED. I WAS NOT ABLE TO DRIVE FROM THERE. I COULDN'T EVEN SHIFT TO ANY OTHER GEAR. THE CAR WAS STUCK IN A NEUTRAL POSITION, SO I WAS ABLE TO PUSH IT OFF TO THE SIDE. AFTER GETTING A TOW TO THE NEAREST SHOP, THEY DETERMINED THE TRANSMISSION WAS BAD. I DID SOME RESEARCH AND FOUND OUT NISSAN HAD BEEN HAVING ISSUES WITH THIS TYPE OF TRANSMISSION. (CVT) AND THEY EVEN EXTENDED THE TRANS WARRANTY TO 120K. (I HAVE 144K ON THE CAR) I DID CONTACT NISSAN TO SEE IF THEY WOULD MAKE A SMALL EXCEPTION. THEY TOLD ME TO HAVE A NISSAN DEALER CONFIRM THE CVT WAS BAD. I DID SO AND THEY CONFIRMED IT WAS BAD. AFTER I REPORTED BACK TO NISSAN THEY SAID THEY WOULD NOT BE ABLE TO HELP ME IN ANY WAY. THE COST TO GET IT REPLACED IS ABOUT $4200

WHILE DRIVE ON INSTERSTATES AT 65-70MPH FOR 45MINS CVT GOES INTO "SAFE MODE" BC IT IS TOO HOT, WHICH RESULTS IN THE CARS SPEED TO NOT EXCEED 60 MPH ON A 70MPH INTERSTATE, AND CAR DECREASES FROM 60MPH IF TRYING TO GO UP HILLS. WHICH IS GOING TO RESULT IN MANY ACCIDENTS..

I WAS DRIVING ON A WOODED BACK ROAD WHEN AN ANIMAL RAN OUT IN FRONT OF THE CAR. I HIT THE BRAKES HARD ENOUGH TO ENGAGE THE ABS AND COME TO A FULL STOP. IMMEDIATELY AFTER STOPPING I TOOK MY FOOT OFF THE BRAKE AND STEPPED ON THE GAS. THE CAR ACTED LIKE THE BRAKES WERE STILL APPLIED. I SHIFTED BETWEEN DRIVE AND REVERSE MULTIPLE TIMES IN AN ATTEMPT TO FREE UP THE BRAKES. EVENTUALLY I JUST PRESSED HEAVILY ON THE GAS AND THE CAR BEGAN TO MOVE FORWARD SLOWLY AND GRADUALLY PICKED UP SPEED. AFTER SOME 15-30 SECONDS FOLLOWING PRESSING ON THE GAS, THE CAR RESUMED ACTING NORMALLY. THERE WAS A SECOND INCIDENT ON AN INTERSTATE FREEWAY WHEN THE TRAFFIC IN FRONT OF ME SUDDENLY BRAKED HARD. THIS TIME I DID NOT STOP, BUT I FELT THE SAME SENSATION OF THE BRAKES STILL BEING APPLIED. THE NISSAN DEALER HAS REPRODUCED THIS PROBLEM ON MULTIPLE DIFFERENT SENTRAS OF DIFFERENT MODEL YEARS BUT OF THE SAME BASIC GENERATION. NISSAN HAS TOLD ME THAT THE CAR IS WORKING AS DESIGNED AND WILL NOT FIX IT. I BELIEVE THIS IS A DESIGN PROBLEM THAT PRESENTS A SAFETY ISSUE OF LEAVING A CAR UNABLE TO MOVE FOR A SHORT PERIOD OF TIME. *TR

AFTER DRIVING APPROX. 50 MILES AT HIGHWAY SPEEDS 65-70 MPH AND EXITING TO A FULL STOP, ENGINE WOULD REV UP AS USUAL BUT ONLY MOVE 1 MPH. TRANSMISSION NOT FULLY ENGAGED. THIS PUTS ONE IN HARMS WAY WITH NO ABILITY TO MOVE OUT OF THE WAY. OCCURRED IN ALL GEARS. ONLY WAY TO GET BACK TO NORMAL WAS TO SHUT OFF ENGINE AND RESTART. THIS OCCURRED THREE TIMES IN A ROW ON SAME DAY (10/13/2010). DOES NOT HAPPEN IN NORMAL SUBURBAN DRIVING OR SINCE THAT DAY BECAUSE CAR NOT TAKEN ON HIGHWAY SINCE (OR BEFORE 10/13/2010). DEALER (LEITH NISSAN APEX NC) WAS UNABLE TO REPRODUCE OR REPAIR BECAUSE TECH ONLY DROVE CAR FOR 4 MILES ON 50 MILE PER HOUR SUBURBAN ROAD WITH SEVERAL STOPLIGHTS. *TR
