2011 Nissan Altima

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 .

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.
