2011 Nissan Altima Engine Problems

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 by standard non-dealership methods like unplugging the battery.

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 .

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.

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.

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.

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.
