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.

There is issue with sunroof drainage tubs causing rain to soak the floor of car. This definitely malfunction or inadequate problem with drainage tubs and sunroof parts with Nissans. I took it to the dealership and car collision repair shop and was told this is high reoccurring issue with Nissan sunroofs, but no recalls have been given, and I have to pay out pocket to get fixed. At 1st was told just get the drains cleaned out and you shouldn't have that problem again. The issue has progressed and now I have paid for drains to get unclogged 2x so far in one year and keep happening every time its alot of rain at one time. My only option I'm told is to keep getting drains cleaned and unclogged pay out of pocket or get another car without sunroof. I have gotten this done 2 years in row, that's getting too expensive to pay. That's not fair when you know it's problem with these drains and don't do nothing to fix issues. I like cars with sunroofs and have no control over when it rains. I should be able to have a car in 2025 with sunroof and not have this problem. Please help with this issue with factory sunroofs made in original cars not added. Make better drainage system for sunroofs in Nissan and all cars.

I have complained to Nissan that the dash in the car is literally melting. It started around 2014 when I noticed it was having a sticky texture and because of this it creates a glare in the windshield that makes it hard to see. Over the years it has only gotten worse and the dash is literally crumbling. I read online where they have had this issue before. I have tried to get help locally but I am lost no one will help me. This is a really bad safety issue!

I brought my car to Florida 2 years ago and notices my dashboard getting very shiny and sticky. Now the dash is cracking in many areas. The glare off the dash board shining on the windshield makes it a dangerous situation. I called Nissan and they said it is a common problem in years 2005-2012 and there is nothing they can do. I googled it and there are many complaints online regarding this problem. A 13 y/o car that was garaged for 11 years in the NE and now parked underneath a parking garage should not have this problem. It is definitely a defect in manufacturing that is causing a safety issue and a diminished value issue.
