What component or system failed or malfunctioned, and is it available for inspection upon request? The Engine Control Module (ECM) is malfunctioning, triggering persistent P0101 codes related to the Mass Air Flow (MAF) sensor. This specific issue is addressed in Nissan Technical Service Bulletin DE97AA, which recommends an ECM reprogramming. The component is still installed in the vehicle and is available for inspection. ⸻ • How was your safety or the safety of others put at risk? When the vehicle is at a complete stop and I attempt to accelerate, it becomes jumpy and unresponsive, refusing to accelerate properly. This creates a serious safety hazard, especially when trying to merge into traffic or cross intersections, as I am unable to match the speed of other vehicles. This increases the risk of being rear-ended or causing an accident due to unexpectedly slow acceleration. ⸻ • Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. An independent mechanic diagnosed the issue and confirmed the code P0101. After reviewing Nissan’s official TSB DE97AA, they advised me to go to a Nissan dealership to have the ECM reprogrammed as outlined in the bulletin. ⸻ • Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected by an independent mechanic, but not yet by the manufacturer. The dealership is aware of the issue but has refused to perform the repair without payment. ⸻ • Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The Check Engine Light is consistently triggered by code P0101, and the traction control warning light also comes on when the issue is active. The symptoms appeared recently and continue to recur even after the code is reset.

While driving it's difficult for the car to shift gears, also a burning smell comes from the engine after driving long distance.

Unknown. My car is making a whining noise & no matter how much i push the gas pedal it won’t accelerate. Sometimes it works but mostly it won’t.

It started about 2 months ago that the RPM was revving when it came to the gears shifting. I would accelerate and the car would barely move and the transmission was making a whirring sound. The Service Engine Soon light came on so I took my car to O Reilys and the code for the stepper motor came back. I had the stepper motor replaced in my transmission but I am having the same issue. My Mechanic told me that my Transmission is failing and I would need a brand new one.

I was on my way to work driving on the freeway and suddenly I felt a sort of shaking from the car. I then exited the freeway and approached a red light. When the light turned green, my car moved some but then was stalled so I was stuck in the middle of an intersection. Luckily, I wasn’t too far from my job and I was able to eventually ease my way the next few miles. I was later told by a mechanic that it was my transmission that needed to be replaced .

The contact owns a 2011 Nissan Altima. The contact stated that while driving at an unknown speed, the vehicle inadvertently decelerated. The contact stated that the vehicle performed as if the gear shifter was in neutral(N). The check engine warning light was illuminated. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacture was notified of the failure. The failure mileage was approximately 100,000.

Going down interstate, when you press the gas, vehicle hesitates if you are going faster than 40 miles an hour, motor didn't die but you are unable to go faster for a few seconds, this is very dangerous situation on our interstates. And this is happening on every trip that I am afraid to drive this car, its not trustworthy and I can't afford a new car in today's economy.

I was driving in early n all of a sudden car started slowing down n there’s other cars n I have my kids in car was very scary I started praying n calling on Jesus N car slowly started taking off again I just bought used car I’m very worried I hope someone reads this and calls me I never experienced this .

I HAVE REPLACED THE MASS AIR FLOW SENSOR AND THE CODE KEEPS COMING ON. IT ONLY STAYED OFF FOR A MONTH. IT CAUSES THE CAR TO IDLE ROUGH. I AM NOT SURE IF THE OTHER PROBLEMS THAT ARE HAPPENING ARE RELATED BUT THE ONLY LIGHT THAT COMES ON IS THE SERVICE ENGINE LIGHT AND THE CODE SHOWS P0101.

POSSIBLE CVT TRANSMISSION OVER-HEATING/FAIL-SAFE ISSUE? I WAS ON THE HIGHWAY AFTER DRIVING FOR 2 HOURS AND MY ENGINE STARTED MAKING A 'WHIRRING' NOISE AND I HAD TROUBLE ACCELERATING. THE SPEED LIMIT WAS 70 BUT AS MUCH AS I TRIED TO ACCELERATE, IT WOULD BARELY GET PASSED 50MPH. THIS ALMOST CAUSED AN ACCIDENT WITH A SEMI-TRUCK AS WE APPROACHED A HILL BECAUSE I COULD BARELY GET UP IT. I HAD TO PULL OFF THE HIGHWAY AND LET THE CAR REST FOR A WHILE. I HAD TO DRIVE ANOTHER 2 HOURS TO GET HOME AND AFTER ANOTHER HOUR, IT DID THE SAME THING. SOON AFTER, I TOOK IT TO THE DEALER AND THEY SAID THE ONLY THING THEY COULD SUGGEST WAS TO GIVE ME A NEW TRANSMISSION! I GOT A SECOND OPINION FROM A TRANSMISSION REPAIR SHOP AND THEY SAID THAT POSSIBLY ADDING A SECONDARY COOLING SYSTEM WOULD HELP BUT THEY COULDN'T GUARANTEE THAT WOULD FIX THE ISSUE. FROM MY RESEARCH, IT SEEMS THAT A REASON FOR THIS HAPPENING IS THAT THE CVT TRANSMISSION PRODUCES TOO MUCH HEAT FOR THE COOLING SYSTEM TO HANDLE AND EVENTUALLY GOES INTO A FAIL-SAFE MODE THAT CAPS THE ACCELERATION POWER OF THE CAR, IN ORDER TO PROTECT THE TRANSMISSION FROM BEING DAMAGED. I COULD UNDERSTAND THE NEED FOR THE FAIL-SAFE TO KICK IN IN EXTREME CIRCUMSTANCES BUT NOT AFTER DRIVING FOR 2 HOURS AT REGULAR HIGHWAY SPEEDS. THIS IS NOT NORMAL AND EXTREMELY AGGRAVATING. I HAVE READ THAT THIS IS A COMMON SAFETY ISSUE WHICH AFFECTS BOTH NEW AND OLDER CARS AND NISSAN CHOOSES TO DO NOTHING ABOUT IT. I HAVE NOT BEEN ABLE TO DRIVE MY CAR MORE THAN AN HOUR ON THE HIGHWAY BECAUSE IT STARTS TO MAKE THAT 'WHIRRING' NOISE AND I KNOW IT WON'T BE LONG BEFORE THE FAIL-SAFE KICKS IN. THIS HAS BEEN BEYOND DISAPPOINTING AND EVEN MORE SO THAT NISSAN WON'T TAKE RESPONSIBILITY TO IMPROVE THEIR CVT ISSUES AND PROVIDE THE NECESSARY REPAIRS. I OWN MY CAR OUTRIGHT BUT THE WARRANTY HAS EXPIRED. NO OPTION FOR THAT ROUTE. VERY INCONVENIENT.

DEFECT IN IN THE ECM. WENT TO WORK CAR STARTED FINE AND WHEN I WENT OUT FOR LUNCH PUSH THE START BUTTON ALL LIGHTS CAME IN IN THE DASH BUT THE CAR WOULD NOT TURN OVER THE ENGINE. THIS HAPPENED ON FRANKFORD AVE, PHILADELPHIA, PA 19135 ON 5/1/2019.

WHEN DRIVING FOR ABOUT 45 MIN OR MORE AND MAYBE A LITTLE HOTTER THAN USUAL, AND YOU ARE DRIVING ON A FREEWAY OR HIGHWAY, THE SPEED WILL LOCK AT 65 OR UNDER, IT WILL NOT LET YOU GO ANY HIGHER, WHEN IT LOCKS IT SLOWS DOWN FAST LIKE IF HITTING THE BREAKS, THIS IS SO DANGEROUS WHEN ON FREEWAY WE HAVE BEEN SO CLOSE TO ACCIDENTS BECAUSE OF THIS, WE TRAVEL ON THE CAR, AND IT HAS DONE IT A LOT LATELY, WE KNOW NOTHING OF WHY IT'S THIS WAY.

Mileage: 40

THE VEHICLE BEGAN MAKING A WHINING NOISE DURING ACCELERATION AND THEN LOSS POWER ON THE INTERSTATE AND WOULD NOT GO OVER 40MPH EVEN WITH THE GAS PEDAL DEPRESSED ALL THE WAY MAKING A VERY UNSAFE SITUATION FOR MY FAMILY. I'VE DONE RESEARCH AND FOUND SEVERAL OTHER OWNERS COMPLAINING OF THE SAME ISSUE AND RECEIVING NO ASSISTANCE FROM NISSAN ON THIS OBVIOUS SAFETY ISSUE.

I WAS DRIVING TO THE AIRPORT AND OUT OF NO WHERE, MY CAR STARTS JERKING AND SPUTTERING WHILE DRIVING DOWN THE ROAD TO THE DROP OFF TERMINALS. I LOST ALL ACCELERATION CONTROL AND COULDN'T EVEN MOVE. I WAS ABLE TO PULL OVER AND HAD TO HAVE MY CAR TOWED. TURNS OUT 2011 NISSAN ALTIMA HAS VERY COMMON CVT TRANSMISSION PROBLEMS. IT IS UNABLE TO DRIVE WITHOUT JERKING, SPUTTERING, OR EVEN MOVING. I CALL THE 1-800 NUMBER FOR NISSAN AND THEY SAID THERE WASN'T A RECALL FOR THE TRANSMISSION FOR THIS VEHICLE. I WAS TOLD TO TAKE IT DOWN AND HAVE IT DIAGNOSED AND THEY CAN REVIEW IT WITH NO GUARANTEE OR PROMISE OF A POSITIVE OUTCOME. TRANSMISSIONS FOR THIS VEHICLE TO BE REPLACED ARE AROUND $4000.

I HAVE A NISSAN ALTIMA (2011) AND MY SISTER HAS A NISSAN MURANO (2013?). BOTH CARS REMAIN RUNNING WHEN THE "SMART KEY" IS REMOVED. MY CAR BEEPS 3 TIMES IF I GET OUT WITH THE KEY WHEN IT IS RUNNING, BUT NOT MUCH NOTIFICATION. I HAVE NOT HAD A PROBLEM YET, BUT MY SISTER, IN HER 80'S, HAS LEFT HER CAR RUNNING FOR HOURS FREQUENTLY SINCE SHE BOUGHT THE MURANO (AT LEAST 5 TIMES). WE BOTH KEEP OUR CARS IN A CLOSED IN BASEMENT AND IF LEFT RUNNING COULD BE DEADLY. OUR BEDROOMS ARE DIRECTLY OVER THE GARAGE. IT SEEMS LIKE A SIMPLE TIMER COULD BE USED TO TURN THE CAR OFF IF THE KEY IS REMOVED FOR MORE THAN 5 MINUTES. AN OVER RIDE COULD BE PUT ON THE OPTION IF THE OWNER WANTS IT TO RUN LONGER FOR WINTER WARM-UPS OR WHATEVER. THE SOONER THE AUTO COMPLEX FIXES THIS THE FEWER RECALLS IN THE FUTURE. I REALLY WORRY ABOUT MY SISTER AND OTHERS NOT AS TECH SAVVY OR MAYBE WITH MEMORY/ATTENTION ISSUES. THE INCIDENT DATE ABOVE IS CLOSE TO THE DATE THAT I BOUGHT THE CAR NEW, SINCE THIS ISSUE EXISTED THE DAY THAT I BOUGHT IT. I WAS NOT AWARE OF THE DANGER UNTIL MY SISTER REPEATEDLY LEFT HERS RUNNING UNKNOWINGLY. I'M SURE THAT YOU ARE AWARE THAT THIS PROBLEM MAY NOT BE NISSAN SPECIFIC AND ALL COMPANIES WILL NEED TO FIX IT. THANK YOU FOR YOUR HELP. *TR

TL* THE CONTACT OWNS A 2011 NISSAN ALTIMA. WHILE DRIVING AT 65 MPH, THE CONTACT STATED THAT THE VEHICLE JERKED UNCONTROLLABLY AND SHUT OFF WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

THE CHECK ENGINE LIGHT LIT ON THE DASHBOARD. THE ASSOCIATED ENGINE CODE WAS P2A00 AND BOTH THE UPSTREAM (AIR/FUEL RATIO) AND DOWNSTREAM (OXYGEN) AIR SENSORS HAD TO BE REPLACED. THE REPAIR COST CLOSE TO $1,000 PLEASE NOTE: THIS IS AFTER MANY OTHER COSTLY REPAIRS, INCLUDING MOST RECENTLY ANOTHER FILING WITH THE NHTSA REGARDING ISSUES WITH THE POWER STEERING SYSTEM WHERE THE RACK & PINION HAD TO BE REPLACED. WHILE THE CAR HAS A LOT OF MILES, THEY'RE MAINLY HIGHWAY MILES AND THE CAR HAS BEEN EXTREMELY WELL MAINTAINED. ADDITIONALLY PLEASE NOTE: THE CATALYTIC CONVERTER WAS REPLACED ~33K MILES AGO. DURING THIS REPLACEMENT, SUPPOSEDLY, THE AFOREMENTIONED SENSORS SHOULD'VE BEEN CHECKED AND POSSIBLY REPLACED. *TR

I WAS IN A BUMPER TO BUMPER ACCIDENT AND THE FRONT END OF MY CAR WAS SMOOCHED IN. MY CHEST HIT THE STEERING WHEEL (MY SEAT BELT WAS BUCKLED) KNOCKING THE AIR OUT OF ME, BUT MY AIRBAGS DID NOT DEPLOY. WE HAVE TAKEN OUR CAR INTO THE DEALERSHIP SEVERAL TIMES TO COMPLAIN ABOUT THE PASSENGER AIRBAG SENSOR. EVERY TIME WE GET IT BACK WE GET THE SAME ANSWER "WE DON'T SEE ANYTHING WRONG WITH THE SENSOR". WE RECENTLY TOOK OUR CAR IN 2 WEEKS PRIOR TO THE ACCIDENT AND WE ASKED THEM IF OUR CAR WAS ON THE AIR BAG RECALL LIST THAT WAS ALL OVER THE NEWS. THEY TOLD US NOT TO WORRY ABOUT ANYTHING BECAUSE OUR CAR WAS NOT ON THAT LIST. I ENDED UP IN URGENT CARE AFTER THE ACCIDENT WITH MUSCLES SPASMS AND A BRUISED CHEST. WHY DIDN'T MY AIRBAGS GO OFF?! *TR

WHILE DRIVING IN CITY TRAFFIC, THE CAR STARTED TO STALL. DRIVER PARKED THE CAR ON THE SIDE OF THE ROAD AND WALKED TO WORK TO AVOID HAVING THE CAR DIE IN A BUSY INTERSECTION. NONE OF THE DASHBOARD WARNING LIGHTS CAME ON TO INDICATE A PROBLEM. WHEN ATTEMPTING TO RETRIEVE THE CAR THAT EVENING, IT COULD NOT BE STARTED AND HAD TO BE TOWED TO A MECHANIC. DESPITE BEING ONLY 3-YEARS OLD AND HAVING GONE JUST 60,022 MILES, THE MECHANIC DISCOVERED THAT THE CAR HAD A CRACKED ENGINE BLOCK! THE ENGINE HAD BEEN WELL MAINTAINED INCLUDING OIL CHANGES EVERY 3,000 MILES. *TR

Mileage: 60,022

I WAS DRIVING 65 MPH ON THE INTERSTATE WHEN THE CAR BEGAN TO LOSE POWER. ALL WARNING LIGHTS CAME ON, THE STEERING BECAME DISABLED AND THE CAR COASTED TO A STOP. WHITE SMOKE CAME OUT FROM UNDER THE HOOD, IT IMMEDIATELY TURNED BLACK AND 60 SECONDS AFTER THE CAR LOST POWER IT WAS ENGULFED IN FLAMES. *TR

Mileage: 26,000

WHEN DRIVER ATTEMPTED TO START VEHICLE, ALL WARNING LIGHTS CAME ON, ALL INTERIOR LIGHTS AND HEADLAMPS & RUNNING LIGHTS CAME ON, AND VEHICLE BECAME TOTALLY UNRESPONSIVE, STRANDING DRIVER & RUNNING DOWN BATTERY DUE TO INABILITY TO TURN ANY LIGHTS OFF OR TURN VEHICLE OFF. NO CONTROLS RELATED TO ELECTRICAL SYSTEM WERE CONTROLLABLE. SOME EXAMPLES INCLUDE: 1. POWER DOOR LOCK SWITCHES DID NOT FUNCTION (NO EFFECT FROM PRESSING). 2. POWER WINDOW SWITCHES DID NOT FUNCTION (NO EFFECT FROM PRESSING). 3. PRESSING THE VEHICLE POWER / IGNITION BUTTON (MODERN EQUIVALENT OF STARTING KEY SWITCH) DID NOT HAVE ANY EFFECT, WHETHER SHORT OR LONG DURATION PRESSES WERE USED, AND REGARDLESS OF DELAY BETWEEN KEY PRESSES. 4. HEADLIGHTS & RUNNING LIGHTS WERE ON REGARDLESS OF THE SWITCH POSITION OF THE HEADLIGHT CONTROL SWITCH. THIS RESULTED IN THE DRIVER BEING STRANDED. BECAUSE THE VEHICLE'S LIGHTING WOULD NOT TURN OFF, THE BATTERY RAN DOWN, DISABLING THE VEHICLE FURTHER. VEHICLE WAS TOWED TO A NISSAN DEALER. NISSAN SERVICEMAN INITIALLY REFUSED TO WRITE THE CUSTOMER PROBLEM DESCRIPTION AS PER THE CUSTOMER DESCRIPTION OF THE PROBLEM. LATER, CUSTOMER CALLED BACK TO THE DEALERSHIP TO REQUEST THE CUSTOMER DESCRIPTION INCLUDE SPECIFIC AND CORRECT INFORMATION ALREADY PROVIDED BY THE CUSTOMER SUCH AS VEHICLE WAS "COMPLETELY UNRESPONSIVE WHILE ALL THE WARNING LIGHT CAME [REMAINED TURNED] ON THE VEHICLE. DOORS WOULD NOT LOCK OR UNLOCK.", THE DEALER REPORTED THAT THE SERVICE TECHNICIAN FOUND TSB NTB12-041. DEALER RECORD READS: "REPROGRAMMED [SIC] BCM UPDATE AS PER TSB. VEHICLE IS NOW OPERATING AS DESIGNED [SIC] AFTER UPDATE." VEHICLE HAS FUNCTIONED NORMALLY SINCE. *TR
