While driving in any condition or weather, my car shutters and make a loud vibration noise which is also felt inside the car whenever the RPM reaches 2000 RPM. It only does it on exactly 2000. Above or below its fine. Ive been to two different Nissan dealerships for the past two years of owning it and they tell me its normal. In colder weather its a lot worse. You can play with the RPM and everytime it will vibrate and you can hear and feel it at 2000 RPM. But both dealers say they cant find anything and that they don't notice it. That worries me when a 5 year old asks me what that noise and feeling is but a certified mechanic cant find this problem. Its loud and clearly you can feel it. This is ridiculous. All I want is for it to be fixed. If not I'm never buying another Nissan product. Ive had the worst experience with this brand and ive owned a lot of brands. Nissan needs to fix this and spend more money on training. This has been going on for 2 years that ive owned this car.

Unfortunately, this is my second Altima 3.5. in 2015 Nissan replaced my 2013 Altima 3.5. I requested a replacement due to the vehicle having stuttering and jerking issues causing me to feel unsafe while driving.while driving if I had to decelerate it would hesitate and jerk or pull while I was accelerating. This mainly happened on the highway but would happen occasionally while driving on city streets.as a mom with kids I feel the car is unsafe and will eventually cause to me be involved in a accident. My car has been in the shop for transmission issues since october2015 and now it is currently in the shop on its 4th attempt.I have currently requested for Nissan to help me get into another vehicle, or replace the vehicle.

While pressing gas my RPM goes up and down really fast even when I'm at a steady pace, the vehicle vibrates and jerks while and motion and has shut off twice while driving. The vibration occurs while in motion. Once while driving the car wouldn't drive over 20mph then it shut off. Often times when I make a complete stop then proceed to go the vehicle does a hard jerk. This has been going on for several months. I've contacted Nissan and they have done nothing to assist despite the fact that I notice on different forums lots of people complaining about the exact same issue starting with the 2013 model and 2015. This car is dangerous and can really become deadly for consumers while randomly shutting off while in motion. I purchased my vehicle with 13000 miles and now its at 25000 theirs no reason thousands of others should be complaining about the same issue with the exact model as mine. This issue has been going on for months now.

Car fails to accelerate after a total stop and sitting at a traffic light. Absolutely no power. The gas pedal can be pressed all the way to the floor before vehicle begins moving. The gas pedal was pressed gradually. After a few seconds of keeping the pedal on the floor, the RPM will spike and the car will slowly begin moving forward. After backing off the pedal completely, the car can be driven normally once the engine slows down and the transmission shifts back. It was approximately 80-85 degrees outside, clear, car was at a slight incline going up a hill.

Bought 2015 Nissan Altima brand new. From day one have had a problem with vehicle. Going above 60 vehicle wants to drift out of lane. Been in contact with Nissan corporation, and they are no help. Say that is how the vehicle is. This car is very unsafe. Nissan sent out a specialist for alitmas, and he said it was normal. He said he did something to help the driving, but it did not help at all. Horrible car. Really wish I could get out of this car, because of this issue. Will not buy another Nissan ever again!!!

I agree with others about Nissan needing to repurchase/compensate for all the issues.this vehicle feels very unsafe and they just push it all off. The power steering makes varying loud, annoying, distracting, whining noises the entire time you drive it. The car hesitates and jerks while driving or trying to drive from a stop which feels very unsafe and makes me worry about being hit. There are so many problems that are unsafe with the 2015 Altima and Nissan refuses to admit them and constantly says "everything is normal" or 'its the way that transmission works". a huge waste of time and energy trying to deal with Nissan. They also kept insisting to me that the airbag light coming on while a grown adult was seated was "normal" as well until all of a sudden there was a recall...just to show how they lie and cover everything up.I bought this car brand new in December 2015 and have had these issues since. Have been to dealership many times for the issues as well as having a Nissan tech come to assess but of course everyone sticks together and states it "all normal".there are also problems that are not safety issues but value issues such as the xm service that is horrible but you pay for and the cheap build of the vehicle/paint.

In my driveway I put car in park and got out closing door. I then realized that the engine was still running, so I opened the door and reached in to push the off button. The car started down the driveway in reverse with me caught between the door and body of car. I was almost run over. It stopped by hitting into an island of trees and shrubs.

I purchased my 2015 Nissan Altima brand new from the dealer. In Sept 2015 at 25,000 miles, while driving in the middle of the freeway, the car slow down as if I was driving in a low gear. The RPM went up, but the car is moving very slow. I stop the car and called the service department. They told me to stop and park the car then restarted the car after giving it serval mins of cooling down. I took the car the service the next day, they couldn't find anything wrong with the car. I continue to drive the car for another six or so months then the same happened again. I took the car back to the service department, no problem was found again. Couple months later, the car stop in the middle of the road. I took the car in, still no problem ws found. They said they can't mimic the problem and asked that I contiue to drive and stop and park if the problem arise. I told the supervisor/manager at the service department that I don't feel safe driving my family around in a car that stop in the middle of the road but can't find anything wrong. I don't know much about the car, but it has to do with transimition because of the check engine light. I felt that the service department is prolonging the real problem because the car is still under the warranity, and I felt that the problem will be discover once it's out of the warrnity coverage. I have two major concerns: 1. I am worry for the safety of my family when I am driving them around the car that can stop anytime in the middle of the road and cause the accident. 2.I am worry, I'll be making a payment for a car that I can't drive once it is no longer be cover under the warranity and it will costs thousand of dollars to get it fix.

The cvt transmission in the 2015 frontier is probably going to fail after 50,000 miles. Most of the time it works, but on occasion it stutters on acceleration from a standstill, or vibrates excessively in general. When, not if, the transmission fails it could cause serious injury or death because the car did not accelerate when it was expected to.
