2018 Nissan Altima Power Train

It seems to be the transmission intermittently. I'd stop, push down on the accelerator and would go like a few MPH. Then it would lunge forward and I'd have to slam on the brakes to avoid hitting the vehicle in front of me. The other thing was it didn't seem to shift from first gear - I ended up redlining it at 7000rpm when only going 45mph. I've read that there is a problem with Nissan cars and the CVT. In answer to your questions: You can inspect it. At a stop/light, I'm always afraid the accelerator will start out slow and then lunge forward and eventually I'll hit another vehicle. The dealer couldn't reproduce the issue after having the vehicle 6 days. After 3, they "re-programmed" as the service manager said it was out-of-date and that doing so may fix the problem. They then tested for a further 3 days and couldn't reproduce it. Vehicle has only been inspected by the local Nissan dealer. There were no warning lights or messages before or after these incidents.

Car started acting strangely on the way to work one morning, rpms would jump all over, it started to jerk, judder, slow to accelerate. That evening it did the same a few minutes after driving it. Got it to a local trusted mechanic who test drive and ran an OBD2 diagnostic check, which returned a P17F0 code. He told me it's serious CVT issues and referred me to the local Nissan dealership. The next day they called with the same diagnosis, CVT failure. Car was around 99,500 miles. The horrible extended warranty company I chose wouldn't honor it, said the car was fine. Nissan dealer argued that it WAS CVT failure and could cause a hazard. Nevertheless, I picked it up on 05/02. The next evening on the way home from work, in heavy traffic at 50 mph, it started lurching, crazy rpms, shuddering, going into neutral then back to D. As I was turning into a packing lot to stop, the CVT completely failed. The car wouldn't accelerate and left me at an almost stand-still in the middle of the left turn, as incoming traffic nearly crashed into me. A motorist helped push it into the parking lot, where it was towed back to Nissan... where it still sits today with a shot CVT. Nissan refused to help or offer any goodwill assistance even though it nearly caused multiple collisions. The car has been maintained perfectly, with CVT service performed at 65k miles and another at 95k miles. NHTSA should mark this issue as a safety hazard as a car that suddenly loses power puts families in danger. A modern car that can't even reach 100k miles before a major failure is pathetic. And Nissan having known about this issue for 10+ years (as made evident by the multiple lawsuits) should be held accountable. One day this massive CVT issue is going to seriously injure someone, or worse.

I want formally lodge a complaint regarding a serious issue with a 2018 Nissan Altima that I purchased from a Nissan dealership on [XXX]. The vehicle, which had 107,000 miles at the time of purchase, has exhibited a critical failure. On [XXX], while I was accelerating to change lanes in rush hour traffic, the car began jerking and suddenly slowed down. This malfunction nearly resulted in a dangerous collision with an 18-wheeler and caused me to be run off the road. This incident could have been catastrophic, and it deeply concerns me, especially since this vehicle was intended for my daughter's commute to and from school. Following this, I had the car towed to the Nissan dealership and was informed that it requires a new transmission. I am shocked to learn that the cost to replace the transmission is $6,200. This is particularly distressing given that I purchased the car less than four months ago and was unaware of the known issues with the CVT transmission. It is unacceptable that vehicles with faulty transmissions are still being sold without adequate warning or extended warranties. Nissan should be required to provide clear disclaimers about potential transmission issues before a sale. The lack of transparency and the high cost of repairs are deeply troubling. Given the severity of this situation and the potential risks involved, I believe that Nissan should take immediate action to address these concerns. The warranty should be extended, and there should be clear warnings provided to potential buyers about the risks associated with the transmission. The current lack of empathy and action from Nissan is disappointing and unacceptable. I urge you to review this situation promptly and provide a satisfactory resolution.

The transmission would shift into neutral while driving down the road, loosing power to the drive train. This happened multiple times on the interstate at higher speeds in the left lane. Cars following came close to hitting me because of the sudden loss of power and speed. Talking with multiple transmission shops and a dealership they stated it was a common problem in the Nissan Altimas. Brought it into a independent transmission repair. First try was a flush and fluid replacement, after a day the issue returned. Next they replaced the transmission with only about 75,000 miles. No warning lights or messages about the failure.

The CVT transmission failed at the light in mid drive. The car started to roll backwards down a highway exit in traffic. I had to blow the horn and scream out the window to keep from hitting other cars. As the car ascended down the hill, it completely stopped midway and I was unable to remove it from the street. I had to place my hazardous lights on, and push the car off the ramp. I had a Nissan dealership review the vehicle and in return they stated that the actual belt in the CVT was worn down or completely gone and that the entire CVT transmission would have to be fixed. There was no warnings that happened to notify me that there was an actual issue with the vehicle. In addition, I do have a 2015 Nissan Altima who is now showing possible issues with the CVT transmission and it has less than 90,000 miles

With a little under 68,000 miles on my 2018 Nissan Altima the transmission started shuttering and slipping. No lights came on the dash but the car was difficult to control. After going to get some dry gas and see if it was motor related the car made a loud squealing noise, the check engine light came on and then the car shuttered the rest of the way home . The car goes in to the Nissan dealership in two days. They told me that I hadn't brought it in to have the transmission for it's 60,000 mile flush but I never recieved a notification. in addition, the car went in for a hood latch replacement at that time but nothing was said then. The car could easily be dangerous if this happened while driving in traffic or trying to pull into traffic.

My 2018 Nissan Altima just now reached 100,000 miles on it. I was heading home from work on the interstate when my RPMs started revving up and down and it felt I lost power when I was hitting the gas. My transmission started sputtering, vibrating, slipping. When I place it in drive or reverse now it takes time to go in gear. I took my car to get regular maintenance such as oil change and fluids to see if it was the transmission fluid. The dealership maintenance department did the maintenance and fluids and my car is still doing the same. I asked of the transmission fluid was low I was told it wasn't and I stated about the transmission acting up and was told by the worker yeah I could tell when I took it back and brought it up. The worker stated it was probably the CVT in my car and it costs $5500 to fix and stated this was an issue on models before mine that got extended warranties and the issues was taking place in the model of my vehicle but no extended warranty. This CVT is something that continues to mess up in Nissan and in the 2018 and current models. Either there needs to be a recall or extended warranties or both.

2018 Nissan Altima and Sentra cars have faulty continuously variable transmissions (CVTs) that cause juddering, shuddering, clunking, jerking and acceleration problems. This happen while driving on the highway at a speed of 75 mph. This caused me swerve and almost rear ended by another car.

On several occasions my vehicle fails to accelerate putting passengers and myself in grave danger. Nissan mechanics say they cannot replicate my incidents however they are aware that the problem exists with CVT engines made by Nissan. Nissan of America refuses to acknowledge that there is a problem although thousands of people have posted exact issue on owners forums for years.

The car doesn't move and the car shakes above 55 miles and I can smell smoke under the hood.

The contact owns a 2018 Nissan Altima. The contact stated that while driving approximately 50 MPH, the vehicle suddenly lost motive power without warning. The contact coasted to the side of the road and was unable to restart the vehicle. The vehicle was towed to the dealer who diagnosed that the transmission failed and needed to be repaired. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 69,000.

CVT transmission failure while in transport. It put my family at risk being stranded on busy highway. No warning lights or indication of issue except vehicle stopped performing effectively. The dealer acknowledged issues in this and other models and had transmission repaired at my cost. Vehicle was diagnosed by dealer which using OBD they found transmission failure codes..

According to Nissan dealership My 2018 Nissan Altima CVT failed. They were able to determined the failed cvt with a diagnosis code P17F0. I have 73,694 miles on my car and my warranty ended at 60,000 miles. In previous years model of the Nissan Altima there were recalls on CVT transmissions for the Nissan Altimas. Nissan stated being that my car is out of warranty the only thing they can do is give me 50% good will because my VIN number is different from the other Nissan Altima that had a failed CVT. I don’t feel that it was good will being that my car did not reach 100,000 miles and I’m already having an issue that has been a problem In the past. I keep up with the maintenance of my vehicle very well and this problem occurred out of the blue. I also spoke with Nissan about the current recall on my car being that I have to drive a car around and my hood could possibly fly off at any giving time. Me being a Nissan customer with such a dangerous vehicle that Nissan continues to have issues with is more good will than they’ve offered. I honestly would not recommend such an unsafe vehicle to anyone who is interested in purchasing a Nissan Altima. My car is fairly new and I’m having CVT issues. My car literally stopped in the middle of the road and would not accelerate because of a mechanically failing CVT. I highly recommend that Nissan Recall any vehicles that have CVT issues especially since it’s been a repeating cycle. I hope this doesn’t go unnoticed. Thank you
