2018 Nissan Sentra power train problems

“On Wednesday July 8, 2026 at approx 7:45 AM The powertrain system failed entirely due to a catastrophic malfunction of the Xtronic CVT (Continuously Variable Transmission), which completely and instantly failed with absolutely no prior dashboard warning lamps, check engine lights, or symptoms. While traveling at approximately 40 MPH on a public road, this unexpected defect caused an immediate and total loss of vehicle propulsion in active traffic, forcing following vehicles to brake aggressively to avoid a high-speed rear-end collision. With zero throttle response or engine acceleration, my safety was severely compromised as I was forced to blindly coast across active lanes of traffic to reach a gas station with barely enough power to get into the station lot to escape the hazard. This is a highly busy area and gas station, making it even harder. The vehicle is currently sitting at an authorized Nissan dealership service department, where technicians formally inspected the vehicle, confirmed a total internal failure of the CVT unit, and issued a $5,800 replacement quote. The vehicle and the failed transmission component remain fully available for inspection upon request.”

“At right under 67,000 miles, the car made a loud pop when I went to accelerate from a stop light. The car would only work in reverse at that point. I'm being told that the CVT needs to be replaced. The car isn't even worth the cost of a new transmission.”

“Transmission Replacement - The transmission system requires replacement due to issues identified during inspection, including judder in the CVT and auxiliary gearbox. Replacing the transmission can help address these concerns and improve the smoothn”

“Transmission has already been replaced with a new CVT transmission and the Nissan dealership has also had to put something back in the transmission because it came out and then last night when driving I went to turn and it wouldn't go and now it won't go into gear and it rolls even in park”

“Driving down the road with a lot of traffic then my car didn't want to shift into gear the it went into gear real hard then I hear load noise under the the car then I was no longer moving. So me and some friends push it out of the road and I call tow truck to take to my house I know a lot of people have the same issue with cvt transmission”

“I am writing to express my deep concern and frustration regarding the transmission issues in my 2018 Nissan Sentra. It is widely known, including to the past recalls of similar models that Nissan has an ongoing problems with its continually very reliable transmission CVT. Despite this, no recall has been issued for 2018 Sentra, even though the many customers myself include our experienced significant transmission problems. I had my transmission replaced in 2023 not knowing it was already a problem with Nissan. It was covered through my extended warranty. Now 2 years later I am having the same problem again.”
