Owner reports
Selected complaints filed with NHTSA by 2014 Nissan Altima owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owned a 2014 Nissan Altima. The contact stated that while driving at various speeds, the vehicle stalled. The accelerator pedal was depressed but the vehicle hesitated and was slow to respond while continuing to jerk. The RPMs revved up and was fluctuating. There were no warning lights illuminated. The vehicle was taken to the local dealer and the contact was informed that the warranty coverage was denied due to the transmission fluid not being flushed and replaced. The vehicle was diagnosed, and it was determined that the transmission needed to be replaced. The vehicle was repaired and later sold. The manufacturer was not contacted. The approximate failure mileage was 116,000.
I own a Nissan Altima 2014 SV 4 cylinder. While driving the car stops moving and it just relies on momentum, the gas pedal stops functioning. This has happened to me multiple times I then have to turn off the car and turn it back on so it can work and it does the same thing again. I stepped on the gas pedal all the way to the floor and it doesn't respond. I started doing research and I ran into this website where people are suffering from the same problem and it has put my life and multiple people's lives in danger. These cars all range in year but the make and model is the same, Nissan Altima. I saw some posts that stated that they had the same problem with very low mileage on their vehicles. I took it to the dealership they weren't able to fix it and they gave it to me back malfunctioning and with the same safety issue and the check engine light on. …
transmission felt as if it was slipping into different gears while driving forward. pulled vehicle over put it in park and then put it in reverse- at that time the vehicle went forward instead of reverse. at that time the vehicle was put into park and turned off. Waited a few minutes and then turned vehicle back on, put it into drive and it took 10 sec to drive forward I then put the vehicle in reverse and the same thing happened, it took 10 seconds to move in reverse. took the vehicle in and the repair man said it was the CVT- I have 93K miles on the car. It has been in storage since July 2020.
When the car is at a complete stop and the light turns green and it's time to go it has a small delay for about 4-6 seconds where the car won't move. It picks up after those 4-6 seconds. Once you turn off the car it resets itself but later on through the day it happens again . It happens to me about 2 times a day. It's extremely scary when you're in traffic and your car Just sits there because you can't go.
While driving the car will suddenly jerk and starts to shake and when pressing the gas the car will not accelerate so I have had to turn on emergency lights to not get hit in the back the rpm goes up but not the mph
Pulled into a handicap parking place, all of a sudden the car accelerated forward at a high speed. Knocking down the handicap sign and went through a store glass window.we sat there in shock not nothing what just happened. The police arrived and a said it must have been the gas pedal, they assume since I was a older person that I had stepped on the gas pedal instead of the brake. I know I had my foot on the brake. I feel this is differently a recall problem. Nissan has had this problem since 2000 and no one has done anything about it. I have lost my license and my insurance over this. Please take this matter seriously! What if this was a school crosswalk and children were going across. I worked in the hospital for 47 years now it's time for me to travel and enjoy my retirement. I can't even go to the doctors or grocery stores. Please save our children and our community. …

I purchased a brand new 2014 Nissan Altima sv from baker Nissan north in houston, texas (19630 northwest fwy, houston, tx 77065 [phone]). My transmission has failed twice (replaced the first time and now having to be replaced again) and I have been getting the run around from the dealership. This issue should not be occurring with a brand new vehicle. Then to top it off I have been a loyal customer and have purchased a total of four cars from this dealership now. I filed a consumer affairs report with Nissan corporation and have yet to hear something. I also called the dealership again to speak with someone in charge such as the general manager and they informed me to contact the consumers affairs department with Nissan corporation. They said they have a chain of command to follow and that would be my best bet of getting the situation resolved. …
I purchased my 2014 Nissan Altima with only 6 miles on it in 2014. I only drove my car from school to home, as this was my work vehicle. I finished paying for my Nissan in November of 2019. My Nissan recently reached 90,000 miles and began to shut down in the middle of traffic. The engine began to jerk and it would not move it were placed in drive or reverse. Then at times when placed in drive the engine would shake and roar loudly, and shut off. My dad had to come and tow the car in twice due to it not shutting down on the interstate and in traffic. The Nissan would just stop accelerating and lose power. If it cranked back up at stop lights or stop signs it would accelerate so slowly that I would get caught under red lights or in the middle of on-coming traffic. …
