2018 Nissan Sentra Complaints

POWER TRAIN — Filed 07/08/2026

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.

My vehicle stalled. I had to get someone to help me move it out if a busy traffic thoroughfare. It was making odd noises then was stuck in reverse only. I took it to my mechanic who informed me the transmission had failed and that I needed a new one. I work from home and do not drive my vehicle consistently.

SERVICE BRAKES — Filed 10/20/2025

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

The engine will not crank when pressing the push-button ignition switch and applying the brake pedal. I took it to the Nissan dealership and they told me it needed a new stop lamp switch which is EXACTLY what the recall for other Nissans during this time frame is for: Make: Nissan Number: PM971 Title: Stop Lamp Switch Voluntary Safety Recall Campaign Date: 3/3/2021 Models: 2016-2019 Sentra Summary: Nissan is issuing a Voluntary Safety Recall on specific 2016-2019 Sentra (B17) vehicles identified in Service Comm to address a stop lamp switch concern. The stop lamp switch on the subject vehicles may become contaminated with silicon off-gassing from silicon-based grease used in surrounding components (HVAC and brake booster clevis pin) in close proximity. Oxidation may occur at the switch contact surface due to electric arcing, resulting in silicon dioxide build-up. This build-up may lead to open circuit issues and an inoperative stop lamp switch. If this condition occurs, the customer may notice illumination of the Anti-Lock Braking (ABS) or Vehicle Dynamic Control (VDC) warning lamp(s), the rear stop lamps may not illuminate and/or the engine may not start. Rear stop lamps not illuminating could potentially increase the risk of a crash.

VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM — Filed 12/31/1969

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 further investigated so that it's safe to drive without putting the driver or someone driving by in danger .I just paid this off , and have kept up with oil changes , yet I feel like this car has more issues than what I can fix and that's why I'm writing this to inform you of the dangers that this kinda car has while out on the roads .I hope that someone takes a deeper look at any type of reports from everyday people and make it easier for someone to find out how to report things like this ,because honestly I was looking for recalls about my car when I came across this, otherwise I wouldn't have ever known that this is even exists.. Thanks for having a space for people to express thier concerns and I'll be sure to share this site with others so that everyone on the road is safe
