2018 Nissan Sentra 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.”

“My brake lights suddenly wouldn’t turn on and my car wouldn’t start. We replaced the brake light switch and it worked for a short while, but it stopped working the same day almost causing several collisions as brake lights won’t turn on. There was a recall on this issue with this year and model, but my VIN number was not included regardless of the symptoms all being there. We had a master mechanic look and diagnose it as a brake light switch issue. The vehicle has been brought to a local Nissan center for similar issues a couple months ago, but it failed several times”

“Unknown, ICC module is out on Sentra is known issue from Nissan, needs to be recalled as it can cause some cars to brake on there own from what I’ve seen online. Nissan wants over 2000 to make repair on a part they know from the factory is likely to fail”

“Car won't start, stranded in parking lots, on road. Have seen hundreds of complaints about the same thing ,saying it's either a brake switch or ignition switch.Very scary to be stranded somewhere.Nissan is aware and said it's common problem? Hard to believe Nissan or the nhtsa does not believe this to be a safety issue.”

“When I first get in the car and hit the gas it's OK a if I'm trying to move it but if I'm trying to leave my driveway and I hit the gas it will stall and the rpm will go up to a 5 , and this happens exiting the interstate, it's almost caused me to wreck because I can't pick up the speed it is like it's stuck . The same thing happens at a stop light and trying to move forward, extremely dangerous when you can't judge your distance if you're turning if another car will hit you .I try to only take back roads because I don't want my family, or someone else's family hurt .Sometimes all of the lights pop up on my dashboard like a Christmas tree, but when I take it to auto zone they say that it's nothing, days later it will turn off .Sometimes my car will warn me that I'm about to hit a car, yet no car in front of me , but there's times I've almost hit a car and it never warned me , this to is extremely dangerous. I understand that the car is having some sort of technical issues, but I can't seem to find the answers as to why , and this causes me anxiety every day that I drive because I don't know what to expect from it .I feel like the Nissan Sentra needs to be…”

“The CVT can cause the car to shake, judder, stall during sudden acceleration, or completely lose power. My car jurked and stop completely while at a turning signal in the middle of the street . This was cause by the recall on their cvt. I’ve called a Nissan dealer and they said they can’t fix the recall problem for free because my car is over 80,000 miles. No it hasn’t been inspected . Yes my car has been jurking for the last past month . I’ve been called Nissan about it but they said i had to pay $210 for diagnostic even tho the problem was the transmission recall . The car will not drive foward or backwards . It’ll start up but that’s just about it. Now I have no transportation to go to work or doctors appointments.”
