2019 Nissan Altima

Odometer Fraud. The contact purchased a 2019 Nissan Altima. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 60,000. It was later discovered upon checking a Carfax Report that the mileage was 180,000.

I recently bought a 2019 Nissan Altima SR and when I got it home I noticed the door locks weren't locking or unlocking on 3 doors! The salesman didn't mention any problems with the car and I inspected it and didn't notice this until I got it home. This is a safety issue and everything should work on a vehicle when one buys it. There were no warnings and I have a family with two teen kids and one drives. I've reported this to the dealer and they haven't responded yet. I don't feel safe in the car with this problem and I also saw this is a common complaint on different websites. I can't afford to shell out more money for a repair that should of been done before they sold it to me. There should be an immediate recall that nissan needs to address this.

A truck was turning without signaling and we were passing on right side assuming he was turning left- and he suddenly jerked right causing major impact and sent us into ditch where we were stopped by impacting a solid fence.

I’ve owned this vehicle since March 2023, and I have experienced several electrical issues. For instance, my car displays a malfunction warning and the check engine light multiple times throughout the month. When the engine malfunction warning appears, the engine will not accelerate, and if the vehicle is idling, it will shut off. I then have to restart the car. Another issue involves the door locks. I am sometimes unable to lock my doors using the key, or the lock will get stuck and not open. I have also seen other complaints reporting the same issue. This is concerning and poses a safety hazard.

When putting my vehicle in reverse, I noticed the screen on the back up camera was blank/black color and did not show the angles/guide of which I was parking. I also noticed on my dashboard the clock at some point changed to "am" and said 109am when it was 529pm so I had to manually change the time. I never disconnected the battery for this to have happened. Everything else shows on the screen EXCEPT for the use of the back up camera so it must be a glitch with the software or wiring

Every time I put the breaks on or go over any kind of speed bump, it bounces and sounds like warn out bed springs. Out of nowhere The volume on my radio will turn up extremely loud. Its happened more than a handful of times while driving and it scared me to the point of having to pull over to gather myself. Some days it doesn’t work at all. The past 3 months, My front passenger window gets stuck and won’t go up without me turning the car off then back on and still at times won’t work. I’ve had no choice but to leave the window down more than enough times and putting plastic over it until it decides to work again. The engine shakes and it feels like the transmission is about to give.

I had my seat warmer on and smelled something burning my coat had caught fire and wires in back of seat were smoking.

On January 5, 2026, my son was driving to work at around 8:30 am EST. While waiting to turn left at a stoplight, his car inadvertently moved forward and collided with an oncoming vehicle. After the collision, he discovered the gas pedal had snapped off, causing the unintended movement. His vehicle was only traveling at 5 MPH or less at the time of impact, so the pedal breakage was not due to the collision. Stranded in the intersection, he was assisted by two individuals who pushed his car to safety. The police arrived, and a report was filed. Our insurance accepted liability for the accident, which was caused by the vehicle's malfunction, not my son's negligence.

My vehicle was taking to the dealership for an inspection for the nissan engine recall. During the inspection metal was found in my oil pan which the recall states they must repair or replace engine if any metal is found. I was told the engine would be replaced on 11/15/2025 but 2 days later 11/17/2025 I was contacted saying nissan denied my recall repair and to come back and pickup my vehicle. The recall states if any metal is found they must replace the engine but nissan refuse to fix the issue. The report they showed me Saturday stated oil was in my oil pan but now since they denied the recall the report was changed to nothing was found in oil pan. I notied the manager and after I mentioned that to the service manager they changed the report again stating metal was found.

Thermostat has been replaced twice. Car is still having issues with overheating. First replacement of thermoastat the car ran fine for about 2 months then the car started doing the same thing. It will overheat and then come right down again. Thermostat was replace again and was doing good then the same issue keeps occuring. My car currently has 175000 miles. No warning lights come on when the vehicle begins to overheat

The contact owns a 2019 Nissan Altima. The contact stated that while driving at an undisclosed speed, the vehicle jerked. The check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that lead was found in the oil pan. The vehicle remained at the dealer unrepaired. The contact was informed that the manufacturer was made aware of the failure and declined to complete the recall repairs. The vehicle was not repaired. The contact stated that the check engine warning light remained illuminated. The failure mileage was approximately 96,000.

The airbag system failed to deploy during a collision. The vehicle is currently in not my possession. The airbag control module, sensors, and airbags themselves can be inspected to determine the cause of non-deployment. 2. How was your safety or the safety of others put at risk? My safety was put at significant risk because the airbags did not deploy during the impact. This increased the potential for serious injury to the driver and passengers during the crash, as the airbags are a critical part of the vehicle’s safety system designed to prevent head and chest injuries. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The vehicle has not been inspected by my insurance and considered totaled. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? A police report was filed for the accident, and my insurance company has been notified. The vehicle has been inspected by insurance, but both parties have been informed of the issue and an inspection has been taken place 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights or airbag system messages appeared prior to the crash. The airbag light on the dashboard was functioning normally before the accident, and there were no indications of a malfunction with the safety restraint system.

Passenger side window stopped going up resulting in the window being down at all times. Tried to repair with a master switch replacement was unsuccessful and replaced the window regulator but did not resolve issue. Safety issue for many.

NHTSA Online Complaint Vehicle: 2019 Nissan Altima VIN: [XXX] Recall: R25B1 (NHTSA Recall No. 25V-437) Description of the Problem: My vehicle is affected by recall R25B1 (NHTSA Recall No. 25V-437) related to potential bearing failures in the 2.0L VC-Turbo engine. Nissan announced this recall on June 26, 2025, but the status remains “Incomplete – remedy not yet available.” I have contacted Nissan Consumer Affairs and local dealerships several times, but they confirmed that there is no repair or parts available. Due to this unresolved safety recall, my state’s DMV has refused to register my vehicle, meaning I cannot legally operate it. This delay has caused significant hardship and prevents me from using my vehicle, even though the recall involves a critical safety risk (potential engine failure while driving). I am requesting that NHTSA investigate this issue and require Nissan to expedite a remedy for recall R25B1. I need a car urgently to drive to work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my Nissan Altima in normal operation, the vehicle suddenly and unexpectedly stopped and applied the brakes without any input from me. This occurred without warning and created an extremely dangerous situation. There were no other vehicles, obstacles, or apparent reasons for the vehicle to engage any safety systems. This is a critical safety defect that could have resulted in a serious accident. I was fortunate that no vehicles were following behind me, but this incident could easily cause rear-end collisions or other accidents if it occurs again.

On August 30, 2025, while driving on the highway, my 2019 Nissan Altima displayed a “CVT (AT) Hot / Power Reduced” warning. Power was limited, but the engine did not shut off. I immediately scheduled service at Paul Miller Nissan in Fairfield, CT. At the September 2, 2025 visit, the repair order stated: “Customer states CVT (AT) Hot Power Reduced display in dash. All past codes stored; cleared all past codes stored.” No complete diagnostic test, CVT pressure test, or fluid inspection was performed. The dealership did not preserve the freeze-frame data from the TCM. I was told that no current fault codes were present and that the vehicle was safe to operate. Relying on the dealership’s professional assurance, I continued normal use of the vehicle. About a couple of weeks later, the vehicle began to jerk and lose smooth acceleration intermittently, worsening by the sixth week. I promptly returned for service. On October 21–22, 2025, the same dealership confirmed transmission codes P0776 and P17F0, diagnosing a CVT failure and recommending full replacement. When questioned about prior diagnostic data, the service manager stated that all data from the September visit had been cleared and that the freeze-frame information was deleted and no longer available. This handling contradicts Nissan’s standard CVT diagnostic protocol, which requires documenting stored codes, inspecting CVT fluid condition, and recording internal temperatures before clearing data. Nissan Consumer Affairs later stated their review relied solely on the dealership’s findings and that missing diagnostic data would not be retrieved. Since the confirmed failure, I have been forced to rent a vehicle at my own expense, exceeding $1000 to date. The vehicle’s reduced power and transmission failure created a serious safety risk, especially as I transport my children in this vehicle. The dealership’s erasure of diagnostic evidence prevented accurate evaluation and timely repair. The issue remains unresolved.

The contact owns a 2019 Nissan Altima. The contact stated that while driving at various speeds, the engine overheated and hot air came out of the vents, entering the cabin of the vehicle. The vehicle was taken to the dealer, who diagnosed that the coolant reservoir needed to be refilled. The dealer refilled the coolant reservoir. The failure persisted, and the vehicle was returned to the dealer, who then diagnosed that the radiator thermostat had failed. The thermostat was replaced; however, the failure reoccurred approximately 3 weeks after the repair. While driving approximately 30 MPH, the engine started to overheat, and the temperature gauge moved to "High". The vehicle stalled while on the side of the road and waited for approximately 30 minutes before being able to restart and drive to the residence. The vehicle was taken to the dealer, who diagnosed that the engine and failed and needed to be replaced. The vehicle was not repaired. The contact found information on NHTSA Campaign Numbers: 19V316000 (Fuel System, Gasoline) and 18V922000 (Fuel System, Gasoline); however, the VIN was not included in the recalls. The manufacturer was not made aware of the issue. The failure mileage was approximately 150,000.

The contact owns a 2019 Nissan Altima. The contact became aware that warm air was coming through the vents while the A/C unit was activated. The contact then stated that the vehicle started jerking with the "Engine Malfunction, Power Reduced" message displayed. The vehicle was taken to an independent mechanic, where water was added to the coolant reservoir, and the contact was informed by the mechanic that there was likely an engine coolant leak and to monitor the coolant level. The contact then stated that there was white smoke coming from the vehicle at start up. While inspecting the vehicle, the contact discovered that the coolant reservoir was empty. The vehicle was then taken to a dealer where the contact was informed that the engine had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

I have a 2019 Nissan Altima SR 2.5. I have currently had the car for about 3 or 4 years now. For most of the time I have had the car, the check engine light stays on. I have had it tested, and it always states that it is the Mass Air Flow Sensor. When sitting in park idling, it will "malfunction" and state that the engine is reducing power. During this, the automatic emergency brake warning light and the VDC light will come on. It's rare that it happens while I am driving but it has happened. I recently had the vehicle checked again and again it stated that the Mass Air Flow Sensor and the Grille Shutter Actuator were throwing codes along with some other minor items. I purchased the MAFS and replaced it in hope that this would correct a lot of the idling issues, however after a few days of driving the vehicle, it again has started to malfunction and idle harshly. I do know it typically happens in the morning recently, but I was also having issues with my battery draining for no reason. This car is a certified lemon. I currently don't know what to do, as this sight states I have no unrepaired recalls for this vehicle, and I currently owe too much money to trade it in.
