“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…”

“Loud noise from driver-side rear while driving. I discovered the rear crossmember (aka subframe) is badly corroded and there is a complete break/failure of the unit. This is unsafe. I have worked on cars for over 40 years and I have never seen such an inexcusable failure.”
