2018 Nissan Sentra

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.

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.

When I connect an OBD 2 meter. It cannot read the powertrain and it’s not the first time that I haven’t been able to diagnosed the car. I’ve taken it to a dealership. I’ve been used scan tools from a dealership and mechanics shop. The powertrain isn’t readable it spiders when I drive as in like it feels like the transmission is skipping or going out. It stopped while I was driving by itself like the car brake, and then kept going like it was skipping a gear or had a hard time going to the next gear as well as when we were pulling into a driveway, the wheel on the passenger side went underneath the car like it was only attached by the upper control arm because the lower arm came out of the joint. I’m a driver side a tire is at an angle. The tire is about to fall off or the lower control arm is about to come out of socket impacts the safety of my children and myself when driving down the road is not safe or structurally stable to go down a highway even.

My 2018 Nissan Sentra has under 60,000 miles on it and is on its 3rd set of brake rotors, as well as had both front and rear brake pads replaced 2 times. The vehicle has always given the warning , front radar not detected alert, until the last 12 months where I began receiving a malfunction warning. My car has been brought to 2 different Nissan dealerships to work on this issue. The current one stating my front sensor is failing & will need to be replaced however there is no warranty on it. I am the only owner of my vehicle and it has not been in any forward collisions. As for the power train/transmission, I received a transmission flush in May of 2023, and now 15 months later was told by a different Nissan dealership it needed a flush as it appeared the transmission was going bad. The vehicle has stalled several times, continuously has a high RMP when accelerating and the AC has gone out a couple of months ago.
