general problems of the 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.

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

Tl- the contact owns a 2011 Nissan Altima. The contact stated that while driving at 20 mph, the vehicle decelerated without warning while depressing the accelerator pedal. The contact coast to the side of the road powered off the engine. The vehicle was restarted the failure recurred two minutes after. The vehicle was taken to Nissan 24 dealer, located at 1016 belmont st, brockton, MA 02301, (508) 588-9520, where it was diagnosed that the pcv valve needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 139,640. Aw.

The cvt(transmission) of this model has a history of the transmission overheating and a warning light comes on. The manufacturer "fix" to this is to put in a cooling fan for the transmission at a cost of $1300. If the manufacturers transmission is known to overheat why doesn't Nissan pay for the cooling fan or fix and replace the cvt transmission.

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 get the p0101 code that indicates a mass air flow issue. While driving the car cuts off, stalls, sputters. Often the car can be restarted, but it contines to stutter, or shut off. The issue has occurred while driving on nyc streets and on highways, usually while driving on straight roads. It has also occurred while making a turn. The mechanic changed the mass flow sensor and the vehicle was fine for a few months. Then the issue started again. This repeatedly happens throughout the year. Changing the mass air flow part does not help it. The issue has occurred since 2014, of course usually in may when it's time to get the inspection.
