The car fails to accelerate when I step on the gas pedal. Sometimes it will have delayed acceleration or none at all. The engine will rev but no motion. I also took the car for a smog check in attempt to change ownership and it didn't pass smog a code P0776 came up. Took it to an auto repair shop and they stated it was a transmission problem. Now I'm stuck with this dangerous death trap. This is very dangerous while turning and while on the freeway. It happens periodically with no warning.

This happens when the vehicle is stationary and / or in motion. And no engine or anything con=mes to tell you what is wrong. Mechanics can notfix it, because nothing shows on the diagnostic machine. Sometime when press the gas pedal, the engine does nothing. As if the engine is not even on. After repeatedly pressing the gas pedal the engine will finally respond as it should. It happens frequently.

I was driving on the highway this morning and stopped at the light to make the left turn (about 5 minutes into my drive). Once the light turned green, I stepped on the gas but the car would not move. I had to turn the car off and turn it back on. Pushing on the gas, the car would not accelerate to the more than 40 mph. I turned the car around to go home (about 1 mile away) as I didn't feel it was safe to drive and had to stop at a red light to make the right turn. Once stopped, the car would not move. It was still on and no warning lights were illuminated on the dashboard. I turned the car off and back on and was able to slowly accelerate, again no more than 40 mph. This was scary and dangerous. This could have caused a serious accident.

Intermittent problem the dealer could not duplicate since 25K miles. The car revs and loses speed. Sometimes I press the gas pedal and it will not go for 2-5 secomds. Recently going up a hill the car rolled backwards while I was pressing the gas pedal. Turning the car off can "cure" the symptom until it randomly has the same problem. It is difficult driving in traffic, or deciding to make left turns because I can not depend on acceleration

Every once in a while no matter how far put my foot down on the pedal it will not accelerate. This is extreamly dangerous as it has happened when crossing intersection in very busy traffic situations. I would say I probably would have been hit at least 5 times in this situation, but the drivers coming the other way saw I was having. A problem and slowed down so they would not hit me.

The transmission went out with less than 75000 miles motor mounts bad and air bags does not work. The vehicle was in motion on city street

My 2015 Altima is experiencing a sporadic delay when accelerating from a stop. It won't rev or do anything for a couple of seconds no matter how far down the pedal is. Then all of a sudden it'll go. There is no check engine light on. I took it to pep boys store to see what the problem was. The tech staff experience the same issue I was when he drove my car. He place the diagnostic tool into my car and came up with a code that stated something was wrong with my transmission(P0776 code). Because the store don not deal with transmission, I took it to a Nissan dealership and told them the issue. After running test they did not find any issue with transmission or no code when they inserted the diagnostic tool into my car. They stated they is must have been clear. What I dont understand is how it's clear when no one have done any work on the car. I believe it only happens when the car has been driven and the engine is hot.. I explain this to them too.

My Nissan Altima will randomly have delayed acceleration no matter how hard I push on the gas pedal. At red lights sometimes my car will not move for a few seconds. This has happened multiple times.

- Fallbrook, CA, USA

My car kept cutting off when I am driving. It gives no warning on when it going to turn off. Very dangerous can get a person kill when driving on the highway.

Takata recall.... when vehicle is in traffic on highway at a stand still and you finally get to move the vehicle won't change gears. The RPM will go as high as 8 but the mileage will not go up, it will stay at that lower level speed.

- Dallas, TX, USA

Driving on the freeway at 75mph and the car starts jerking and I was unable to accelerate I believed the car would stop. I managed to to get out of the freeway with the speed coming down and then my car gave out. It is a safety concern. Sometimes I am at a redlight and my car will not accelerate. I have 70,000 miles on my car.

- Turlock, CA, USA

After driving in stop and go traffic for about 30 minutes. Sometimes the gas pedal doesn't respond properly it stalls and goes slow building up speed doesn't respond likes it should. Takes a few seconds to reach proper response

I keep reading the same exact story as mine, yet no recalls or help for this problem on so many Nissan Altima. Sitting still at a redlight, light turns green, your foot is on accelerator but nothing happens for five to ten seconds. Finally the engine begins to rev. Extremely scary when turning in front of traffic. Can also happen when going down the road and all of a sudden the tachometer races, engine races, and wont come down until you pull over and turn the car off and immediately turn it back on. This resets something and everything is okay then. Turning it back on resets the problem so it's obviously a simple issue but it is a very dangerous problem. My whole family has come close on several occasions of being in a serious wreck due to this persistent problem. I'm shocked that Nissan hasn't had a recall on this. I read on the internet that there is a recommendation that the valve body be replaced, but this is not in effect for my particular VIN number. You asked below when this happened. It has happened ever since I had the vehicle for the past two years. Sporadically, maybe once every two to three weeks.

Car will suddenly lose ability to accelerate during hot or cold weather. When this happens, the car will hesitate to move for about 5 seconds then will suddenly begin to accelerate at a very low speed. If I pull over and turn the car off for a few minutes, it behaves normally again. I have almost been involved in several accidents this winter and summer when this has happened in heavy traffic. Please help.

The car started vibrating as if it's going to shift down, the engine light cam on. Took the car to advance auto, was told that the sensor needed to be repaired laced. Took the car to a Nissan dealer had the sensor replaced, drove the car for two days. Driving to work the next day had the same experience this time the car just stopped. Took it back to the Nissan dealer was told that the other sensor needed to be replaced. I'm afraid that I might be driving on a highway and may encounter the same problem I hope to god not, but at this point I'm a bit worried. Had the car for 4 months now.

Nissan seems to have defective ac components in their 2015 Altima vehicles. The below link shows additional individuals that have experienced the exact same issue with their 2015 Altima. The compressor does not always engage, which causes the vehicle to blow out hot air. However, in some cases the compressor clutch will engage and blow out cool air, but it is very inconsistent.

I was driving around a little while and when I came to a stop at a stop light I pushed my gas pedal to accelerate forward and my car did not move, as I pushed my gas pedal all the way to the floor my car would very lightly move. Finally after moving barely forward my car would go, I had cars almost hit me and people getting enraged I am not moving, this is an ongoing problem now, it happens often and sometimes causing a very serious and dangerous situation. After doing my research many of owners of this year make and model are having the same issue but yet nothing to come out from Nissan for recall. I read if you turn your car off and back on it will reset and then the car goes just fine till the next time and that does work but that is dangerous as well. I bought this car as I thought it would be a safe car for my children and myself. This has been a dangerous issue. When we drive it in the heat it happens worst and then will be on the freeway and it will rev the engine really high and not switch down. Please Nissan tell me you are going to do something for your loyal customers this is the third Nissan I have owned. And I have the airbag issue. It wont pick up my son sitting there and he is 160 lbs

Code P0101 oem specific dtc code. Category engine performance - the mass air flow sensor is part of the engine fuel injection system. When driving the engine feels like it struggling to accelerate.

- Ontario, CA, USA

When temperatures are 15 degrees, or lower the engine makes a loud rumbling and knocking noise when started up. The colder it is the louder and longer it last. Generally it takes 5-10+ minutes before it quiets down. Second issue is; regardless of temperature, when accelerating on a grade it also makes a rumbling noise. The car has 57,000 on it and is very good condition otherwise
