2015 Nissan Altima: sudden loss of power

Filed Jun 14, 2026 · Transmission · NY

Subject: Dangerous Transmission Failure in 2015 Nissan Altima While my 2015 Nissan Altima has always exhibited questionable performance—including abnormal acceleration, hesitation during throttle response, and mismatched RPMs relative to acceleration—the transmission has now begun to severely slip. I have also experienced sudden loss of power, pronounced shuddering, and complete power failure while driving. On multiple occasions, these issues have placed me in dangerous driving situations. It is important to note that I have regularly maintained the vehicle and kept it in mechanically decent shape throughout my ownership. I believe it is critical for other drivers to be aware of these ongoing problems, especially since Nissan appears to be avoiding responsibility for manufacturing such faulty powertrains. New car buyers and those purchasing used vehicles are becoming victims of this defective transmission, which poses a serious risk to passengers, drivers, and others on the road.

While driving down the interstate at 70 miles per hour, going up an incline, the car lost ALL power & then jerked kicking back into gear. Once off the interstate attempting to get to a safe place, it completely shut off without warning! No check engine lights or any warning lights. Just randomly shuts off. After replacing what was assumed as the mass flow air sensor ($186.00) & the crankshaft sensor ($80) it continues to have issues. The battery (new battery $220) was also replaced & the alternator checked due to randomly shutting off-which checked out to be fine. Come to find out it’s the CVT judder. After reading all the complaints, I’m confused as to why there isn’t a recall or extended warranty on the transmission. My car only has 119k miles! We should not be having issues with these transmission.

At less than 68,000 miles, the timing chain started to fail. There were oil leaks reported over 6,000 miles before but dealer said it was due to the oil change, but we now know it was the valve cover gasket. Losing power due to engine failure would be unsafe given power steering gone etc...

My 2015 Nissan Altima SV begin losing power and revving up and RPMs but would not move. When I exited the interstate to see what was going on because at that time the check engine light had also come on I came to the stop sign and when I proceeded to move forward to find somewhere safe to park the vehicle would not go but the accelerator but the RPMs went up. Putting my wife's life and myself in danger of uncommon traffic because vehicle barely wanted to move I had the vehicle towed to Nissan dealership in the following morning the service manager called me and let me know that they checked out the vehicle and that it was a transmission and also the speed control sensor he said there was no recalls on it but did have three six and 12 month financing so that they can continue to do the repairs. I am currently just paid the vehicle off two weeks ago and I'm frustrated that this has happened. This was the third time this has happened to this vehicle the first two times my wife had to pull over waited close to an hour as vehicle cool down and then proceeded to continue home which was fine but these are happening every two to three months now.

My teenage daughter drives this car daily and last week upon traveling to work on the highway the RPMs jumped and her car lost acceleration and she wasn’t able to pick the speed back up. She was losing power. The car was shuddering when she was accelerating and taking off and it was jerking with gear shifting. She was almost slammed into from behind when this happened. Dealership is telling us we need a new transmission. We purchased the car in 2016 and Jan 2017 we had the transmission computer module reprogrammed at the dealership, per Nissan recommendation.

Last month I took my altima to my dealer for service. My car shut down on me twice earlier in the week & I was unable to get it started again. While driving down the roadway it would completely lose power.

As I was driving down I-95 south going 70 MPH my car suddenly dropped down to 60 and then 50 MPH and no matter how much a pressed the gas, the car continued to lose power. I barely made it to the next exit and had to drive with my hazard lights on so other drivers knew that I couldn't drive any faster. I pulled into a gas station and let the car sit for approximately 30-45 mins. Before attempting to drive the rest of the way home. During the remainder of my drive, the RPM would all of a sudden jump which caused my car to jerk and accelerate forward without warning. Had someone been in front of me, I would've hit them. As I was taking my car to nissan the next day, my car would stall at red lights and no matter how much I pressed the gas it would take forever to begin moving. This is very dangerous and very scary and I dont feel safe.

Greetings, I am writing this complaint to notify the federal safety agency of a deadly problem with the CVT transmission in the nissan altima! I have experienced this where the vehicle either turns off, stutters, or and hesitates for several seconds. This hesitation is deadly because when pulling out or merging on to a highway there is loss of power and this will cause a fatal accident due to the vehicle not accelerating as expected. In fact, this issue is so prevalent that nisaan reprogrammed the transmission control module (TCM). This half measure is little too little too late as transmission damage has already occurred and it leads to premature failure. This failure leads to the vehicle being a hazard in traffic. I personally have dozens of accounts where this has happened to me. The most recent was on 12/11/17 while driving on a busy street when the car simply lost power and died in the middle of the street. A car behind swerved excessively to avoid hitting me and in doing almost had an accident with another motorist! The car had to be pushed into a nearby parking lot and was towed to the dealership. The dealership ran a diagnostic and confirmed the transmission needed to be replaced. I found this rather dubious as the vehicle is a 2015. I began investigating this issue further. Upon further investigation, I found this problem is extremly prevalent with this model. There are thousands of incidents of owners having an experience akin to mine. Nissan is aware of this problem and has yet to admit fault. The reprogramming of the TCM is a clear indication nissan is aware of the issue and is attempting to remedy it by eliminating certain shift points; however, it is inadequate and the damage has already been done. The lives of people are at stake with this transmission! Is it just of matter of time before the loss of life will occur because of this faulty CVT transmission! Thank you!

When trying to make a turn I randomly lose all power steering. It has happened twice since I've owned the car. I am a second owner and have driven it 4,000 miles.
