2021 Nissan Sentra Problems

My 2021 Nissan Sentra has experienced multiple false Automatic Emergency Braking (phantom braking) events where the vehicle suddenly applies the brakes despite there being no vehicle, pedestrian, or obstacle in its path. This issue occurred before and after my vehicle was serviced by AutoNation Nissan Chandler on June 12, 2026. Despite recent dealership service, the problem continues to occur. The unexpected braking creates a serious safety hazard because it can cause the vehicle to slow or stop unexpectedly in traffic, increasing the risk of a rear-end collision or other accident. I am also concerned that these repeated sudden braking events may be causing excessive stress or premature wear to vehicle components such as the engine mounts, suspension, and struts. Vehicle Information: Year: 2021 Make: Nissan Model: Sentra Mileage: Approximately 139,659 miles I am submitting this complaint because I believe this recurring phantom braking issue is a significant safety concern that should be investigated.

The scope of repair required fixing a recalled tie rod that suffered a catastrophic failure, which directly caused the vehicle’s ADAS, Advanced Emergency Braking (AEB), and collision detection systems to crash. Berman Nissan promised a legally compliant, safe repair but breached this agreement by returning an unsafe vehicle, failing to road-test the steering component (verified by identical check-in/out mileage), and intentionally scrubbing trouble codes to conceal active safety failures. Staff explicitly refused all safety assistance, failed to secure my signature on any authorization paperwork from tow to pick-up, and Nissan corporate stated they were 'not legally required' to resolve the hazards. Service personnel stonewalled the issue, and management only escalated the matter to Service Director Mark Yalda after I disclosed I possessed concrete video proof of the identical mileage and unsigned invoices.

Hello, I am reporting a steering-related issue involving the inner tie rods on my 2021 Nissan Sentra. Nissan previously issued safety recall campaign PM985 for bent inner tie rods on certain Sentra vehicles from the same model year. Two separate repair facilities inspected my vehicle and confirmed problems involving the inner tie rods and steering system components. No warning lamps or dashboard messages appeared prior to the issue being identified. Although my VIN may not currently be included in the recall population, my vehicle is experiencing a similar issue involving the same steering-related component identified in recall PM985. Because tie rods are directly related to steering control and vehicle stability, this issue raises concerns about driving safety. I am submitting this complaint so the issue can be documented and reviewed in case similar failures are occurring outside the current recall population.

The infotainment/radio system in my 2021 Nissan Sentra intermittently reboots and produces static. When this happens, the backup camera freezes or shuts off completely. This has occurred while I was actively reversing, causing a sudden loss of rear visibility. The screen either goes black or restarts, making the backup camera unavailable. This is a safety concern because the backup camera is required for safe reversing, and the failure happens without warning. The issue occurs repeatedly and is not driver-related. The problem appears to be related to the head unit malfunctioning, which disables the backup camera system.

The passenger front, and both back windows no longer function. This appears to be a common issue when searching the internet. There is also an issue with the keyless start, as it often does not recognize that the fob is in the vehicle, or gives a low batter warning (with a new battery). As there was already a recall on the sensor for the blind spot warnings and such, there appears to be wide spread electrical and sensor issues with this year/make/model. The windows pose a safety risk if someone is trapped in a vehicle that the doors won't open.

The contact owns a 2021 Nissan Sentra. The contact stated that while driving approximately 15 MPH, the parking braking independently activated. The failure occurred a second time, and the parking brake unintendedly activated. There was no warning light illuminated. On the third occasion, while driving approximately 45 MPH, the parking brake activated unintendedly, causing the vehicle to stop abruptly, nearly causing a crash with another vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 13,414.

AEB system is initiating emergency braking at random times. Both on surface street, and the freeway on ramp. With and without weather, and without any obstacles or cars in the way. The vehicle comes it a complete stop when this happens and puts the driver in significant danger. At this point the dealer observed warning code on the dashboard, but it did not engage. Message relating to that the AEB may deploy. When it does happen Emergency Brake is on the dashboard. After it happens vehicle can resume driving. Various indicines happened last year. We took it to Ken Garff Nissan (11155 So. Jordan Gateway in South Jordan, Ut. 84095. They could not find the problem or get the problem reproduced. They recommended turning off the safety features when driving. We have done that for a year. Then on 1-15-26, the safety system was on and the break engaged and brought the car to a stop on the freeway on ramp. The car is now at Ken Garff Nissan (777 So. West Temple SLC, Utah) It has been there for 2 weeks. This is the dealer that saw the code, but the system did not engage.

Rattling noise coming from the belt assembly. Tensioner pulley is shaky and alternator had a piece brake off causing metal shavings to fly around.

While driving down the highway along with other traffic the car went into limp mode and lost power instantly almost causing an accident. Come to find out the engine bearings caused the engine to go on it without any warning signs. This car has been maintenanced and taken care of and had the same issue happen that the other nissans have had that they have the recall out for.

When the sun is out and there is no clouds obscuring the sunlight my vehicle has night time lights running, dimming the interior of my car making it difficult to see the speed and other dashboard requirements while perfectly bright and sunny outside and 0800AM as well as 1500PM. This has been going on for two months and I took it in to two dealerships. One told me check your manual and the other went further and told me "by Nissan standards it is functioning normally." This doesn't make sense to me as the sun is out, it isn't dark or dim and yet when on automatic lighting my Night lights, not my normal running lights,,are on and causing me unable to see what's on my dash. Also whe. The sun is hitting the front of my car my Nissas blinks the collision indicator showing it won't do it as something is obstructing it but this happens when the sun is directly pointing in certain areas of the sky. More so early morning and late evening just as the sun is rising and falling.

the car continues to turn off and draining the battery, on the audio there is a constant static, and lights keep shorting out.

Several issues since purchasing vehicle. The front collision sensor malfunction. Came to an abrupt stop several times while on the freeway due to failed sensor. Narrowly avoided major collisions. Also, have had to replace batter every year along with brakes and tires. My suspension is awful. The brakes are crap and have consistently had to address worn tires in one side. Electric panel shit off and key fob malfunctions. So many issues and so much unnecessary repairs with no real results

The check engine light comes on with a malfunction symbol. The car has delay acceleration, jerks, hard shifts.

The competent that continues to fail is the emergency response breaks. They continue to stop at random times creating a very unsafe environment while I drive daily. I do have this on video and my car is available for inspection at any time. I just recently finally got the emergency break system on video since it is so random and plan on making an appointment with my local Nissan Dealer. I did have a visit recently regarding the recall for the tire rods. My car continues to make odd sounds and I paid over $1000 to get it fixed with all new tires. These problems have began since the day I got my car. I have bought over 10 wheels due to issues with the tire rods. The video we finally were able to get was last night regarding the emergency stop systems, it does not let me add to the complaint but I can send to any email if needed as well as the local Nissan dealer did inspect and work on the car for my tires and tire rods.

As I was driving home on the highway, something happened with my car where I couldn't control the car. It swerved back and forth on it's own until it finally stopped and cut off on it's own. There were no messages or symptoms prior to the failure. My car has been with Nissan who said they were going to investigate it and I cannot get a call back from Nissan Consumer Affairs.

The contact owns a 2021 Nissan Sentra. The contact stated that while her husband was driving from a complete stop and depressing the accelerator pedal, the vehicle hesitated to respond. The contact stated that the failure recurred while driving at various speeds, and the vehicle made an abnormal whining sound. The message "CVT Warning" was displayed. The contact stated that the transmission was previously replaced due to the failure; however, the failure persisted. The vehicle was taken to the dealer, where it was being diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 118,000.

The first week of October my car making a terrible sound. My husband took it to South point Nissan Austin Tx. My brand new car needs a transmission It has trouble shifting gears, Making a loud “jet engine” sound. The dealer promised a loaner and never came through with it. I’m driving it as little as possible. Bumming rides and walking while I await a transmission replacement. Yes you are welcome to inspect No prior warning as I stated it’s a new car with 36,700 miles. I have warranty but this transmission is not safe Will replacement be any better?? It’s same transmission.

There is a current open recall Campain ID R23B3 on the tie rods requiring replacement, however there is no current remedy per Nissan. This faulty tie rod can break and cause COMPLETE loss of steering, as there is a STOP SALE on this vehicle it is not safe to drive. Vaden Nissan has my vehicle every 5000 miles during each service/oil change from 2021 until 2024. I also notified the Vaden Nissan dealership again of this open recall issue during my last inspection, they rotated the new tires I had to purchase and sent me on my way. While driving my 2021 Nissan Sentra on [XXX] (a moderately busy highway), I experienced noticeable vibrations through the steering wheel, especially when accelerating and making turns. As I attempted to exit the highway, via a curved off-ramp, the steering wheel became extremely shaky and impossible to turn. I struggled to keep the car within the lane and then completely lost steering control. This caused me to veer off the road and nearly into the shoulder. I experienced such panic and fear as my [XXX] nephew was in the car seat in the back of my vehicle and was also extremely frightened. I am now extremely unsatisfied with Nissan and its lack of commitment to sell safe vehicles, I cannot legally resell this vehicle in the current condition and am left with no option but to drive an unsafe car, under the lemon law I have the right to sue. I pray that IF I absolutely have to drive this Nissan Sentra again there are no injuries, life-altering disabilities or possible death incurred to myself of my passengers. As I have followed all proper protocols and require a rental car that is at minimum safe for transportation.

Wiper will not function. Turning car on/off multiple times will not cause wipers to function. Turned off car and removed all plugs, wipers still will not function. I have a video trying to fix the problem and issue is not resolved. This has happened 5 times already. Took car to dealer ship and they could not replicate issue. We are driving car in Oregon where it rains lots, and with wiper not working our visibility is close to none. This can seriously cause an incident due to low visibility.

Only the driver side window goes up and down. Took it to Nissan dealer and they made it work for that minute and said they were ordering parts, it’s been 3 weeks and haven’t heard of them.
