While driving my 2005 Nissan Altima in active traffic with my [xxx] child, the vehicle suddenly stalled without any warning. The engine completely shut off while in motion, creating an immediately safety hazard in live traffic conditions. Immediately after the stall, I observed oil leakage and smoke entering the cabin. The vehicle became inoperable and we were stranded roadside. This failure is consistent with a known defect involving the crankshaft position sensor and engine control system addressed in NHTSA campaign 07v-527, which describes sudden engine stall without warning due to sensor signal interruption. Although my vehicle previously received recall-related service, this incident suggests the prior remedy did not prevent recurrence of the defect. Sudden engine shutdown while driving in traffic loss of vehicle power without warning smoke entering passenger cabin risk of crash involving child passenger request: I am requesting that NHTSA: review this incident for potential recall remedy failure investigate whether this represents recurrence of a known defect determine whether additional corrective action is needed for this vehicle population information redacted pursuant to the freedom of information act (foia), 5 u.

I purchased a 2022 Nissan Altima from drive time with 90,000 miles on it. I would have had this car for 2 years this month in may. The car currently has about 122,587 miles on it and has transmission cvt failure. I notice pulling, not being able to accelerate while car was in motion, and while car was stop at green light waiting to procced. While hitting the gas the car would go into limp mode and it would be hard to drive. I've gotten three different diagnose that transmission was getting ready to go out.

The engine mounted high pressure fuel pump became loose and unseated because the engine-side mounting threads failed. The pump lifted off its mounting surface, the head of the engine, and oil came out around the top of the engine. This failure caused sudden loss of engine power and created a potential safety hazard because the vehicle could lose power unexpectedly in traffic and there was fluid leakage in the engine compartment near hot engine components. The problem was confirmed by a Nissan dealer. The dealer inspected the vehicle, documented the failed mounting area on the engine head, and submitted a goodwill warranty claim to Nissan, which was denied. Prior to the failure, there were no 18repairs or service in this area from the factory. Symptoms at the time of failure were loss of power and visible oil leakage from the top/right side of the engine. No warning lamps/messages prior to the mechanical failure. Vehicle had 60,845 miles at the time of failure.

The contact owns a 2021 Nissan Altima. The contact stated that after stopping at a traffic light, the accelerator pedal was depressed, and the vehicle went into limp mode. The check engine warning light was illuminated. The vehicle was taken to a local independent mechanic, where it was determined that there was debris in the engine oil pan. The vehicle was taken to a local dealer, and debris was found in the engine oil pan. Upon further investigation, the contact related the failure to nhsta campaign: 26v080000 (engine and engine cooling); however, the VIN was not included. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 118,000.

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.

I continuously have issues with it showing a crash and with the warning "engine malfunction, power reduced, service now" light coming on. This has been a recurring issue. There is always a light coming on in this car. I don't know if it is sensitive sensors or if it was poorly made.

Message popped up while driving saying “engine malfunction power reduced service now”. Pairs with the check engine light coming on.

My 2024 Nissan Altima, with approximately 13,000 miles stalled while driving in 10 degree fahrenheit weather with snow on the road. My speed was around 45 mph. The vehicle immediately stalled and all the lights on the dashboard went on. The warning flashed something about an engine error. The brakes seized up while in snowy weather and with cars very close behind me. Easily could have caused an accident and was a pretty scary event. The car is maintained well and have very low mileage and is taken care of well. I slowed down and then another error screen popped up saying to immediately take care for service. While I was attempted to slow down with brake pedal super hard to push; I attempted to put car in neutral with my hazard lights on by now. Car started again while I was coasting about 20 mph, with engine light showing. I immediately took it to the closest dealership to me for service and left it there. This is completely unacceptable behavior for a new car of this type and I never experience anything ever like this with my old 2012 Nissan Altima. This could have caused a very bad accident had I not been driving and my wife or something else not as calm as me were to be driving. I suggest investigating this because I have read about recalls for this type of thing on previous models of Nissans. Currently vehicle is parked at dealership for service on 1-24-2026.

I received a recall # r25b1 for my Nissan Altima 2020. I visited my local Nissan dealer in chelmsford, MA, on December 30, 2025. They explained that they saw an issue and that I would need a new engine. There are 32,000 miles on this vehicle. They began the process but were then told by Nissan corporate that it did not meet the requirements of the recall, and they would not be replacing it. I am in the process of heading on a long driving trip and am very concerned with how this was handled. Nissan customer relations explained it wasn't covered under warranty, which has nothing to do with a recall. I am very frustrated and disappointed in Nissan. The mechanics at Nissan in chelmsford took photos and sent them to Nissan, and they still denied it. With the car only having 32000 miles on it, it was probably if anything at the beginning of the failure. Please advise on going forward.

Need a new engine / gasket confirmed by pep boys. Been at the dealership a lot more than usual lately and they kept telling me everything is fine with my vehicle.

My mechanic noticed oil leaking near the oil pressure switch during a routine oil change. Told me to take it to dealership since I should still be under warranty. When I took it in, they very quickly were able to access that the oil pressure switch was faulty. Mechanic said it is a known problem. If it is a known issue, why not recall it?!.

Attempted to start 2023 Nissan Altima. Engine did not turn over. Dashboard lights came on and then shut off. No further response. Had Altima towed to Nissan dealer and after two weeks of sitting at the dealership. We were informed that the bcm unit needed to be replaced and fobs reprogrammed. Cause of bcm failure unknown.

This incident happened twice in one week first with 2023 Nissan sentra then replaced with a 2024 Nissan Altima both rented from enterprise. I was traveling down the street from my house, a two-lane, steep hillside road, which I’ve traveled up and down for 30 years. I stopped behind a parked car on the right side of the road to let another car come up the hill and pass by before I continued down. As I continued down the hill, the car just began to accelerate and I could not stop it, I tried to break, but no response and the car kept accelerating for about 50 feet before crashing into. The granite hillside, lifting the car so it landed perpendicular to the road, setting off all airbags and blocking all traffic completely. Thankfully there was no other damage to other cars, homes or people, which was a minor miracle. To reach such an impact speed in such short distance suggests some kind of mechanical failure. My insurance paid for a replacement rental, a 2024 Altima and on my first drive down the hill, in the exact same spot, the steepest of the road, the exact thing happened, rapid acceleration and no breaks.

Problems with the engine and transmission.

I am writing to request immediate assistance regarding the recall inspection for my 2020 Nissan Altima platinum. Last week I received a letter notifying me of an open recall and instructing me to have my vehicle inspected. I brought my car to my local Nissan dealership on Saturday. During the inspection, I was told that metal debris was found in the engine and that the vehicle would need a full engine replacement. I was asked to leave the car at the dealership and was told I would receive a loaner vehicle on Monday. After waiting all day today for an update, I was informed that Nissan declined the engine replacement because the debris found did not “qualify” under the recall. I was told the dealership would clear the debris out of the engine and that I could pick up the car tomorrow. I am very concerned about this decision. Metal debris inside an engine—especially during an active recall related to engine failure—raises serious safety and reliability issues. Simply clearing out the debris does not address the root cause or provide confidence that the vehicle is safe to drive. This matter is urgent, as I must drive more than 1,000 miles soon to take my medically complex daughter to a children’s hospital. I need to trust that my vehicle is safe for long-distance travel. I am requesting a prompt review of my case and a second evaluation to determine whether an engine replacement or another appropriate remedy is necessary to ensure my vehicle’s safety.

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.

Check engine light came on will not go off transmission fluid burnt replaced transmission fluid because transmission was slipping out of gear not finding the correct gear I do believe it was starting off in second gear instead of first. Drive slightly better in manual after fluid gets warm but not overheating the car will start jerking and threatening to kill losing power in the accelerator and going uphill also having trouble with the car going into reverse and drive. I had no choice but to replace the transmission fluid myself due to lack of funds and now dealership refuses to touch my vehicle for repairs. I called Nissan to make a complaint and they hung up on me. Car was just paid off October of 2024. This situation with my transmission began November of 2025.

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.

Check engine light came on at approximately 96,000 miles in which vehicle would have a delayed acceleration upon stepping on gas pedal or going up hills. Took it to 3 different mechanics including Nissan dealer and all confirmed a cvt failure and need a replacement. Nissan of America is refusing to help even after there have been documented lawsuits and known issues with the cvt failing. This is unsafe and a recall is needed not just an extended warranty that doesn’t help consumers who are over the 7 years but still under 100,000 miles like me.

Driving on the freeway and I noticed smoke coming from under the hood so I pulled over and didn't know what caused the fire.

See attached document for complaint.

I have replaced the water pump, the belt, the thermostats, the rotors, the brakes, the fuel pump, the evap vent valve solenoid, the spark plugs, and fuel injectors and my car is still throwing the codes p-0462 and p-447. I've checked the wires and they are good. My car keeps misfiring and stalling now and my fuel pump doesn't have a fuel level sensor. The float bar is brand new as well as the fuel pump. And my dashboard speedometer is 10 miles off. I've tried everything and it's still throwing the same codes.

I’ve had my battery and alternator checked and both are good. Multiple times now my car has either not started until it gets a jump. Took it to a shop and was told its electrical issues. I was at my a football game for my kids out of state and my car would not start after having it off for over an hour,me n my kids were stuck for 3 hours before they got someone out to jump start the car. I take it to another shop tomorrow for additional testing. No lights have appeared and no warning before it happens.

The contact owns a 2020 Nissan Altima. The contact received notification of NHTSA campaign number: 25v437000 (engine and engine cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and a case was filed. The contact had not experienced a failure.

The 2017 Nissan Altima has a delay in acceleration when the gas pedal is pressed. I couldn't accelerate pass 35-40 mph when I was driving. Thankfully it was bumper to bumper traffic.

I’ve received notice that my car is subject to engine failure. I’m afraid to drive it and I need this issue fixed ASAP. What should I do?.

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 2014 Nissan Altima. The contact stated that while her daughter was driving at an undisclosed speed, the air bag and check engine warning lights illuminated. The vehicle was taken to an independent mechanic where it was determined that the air bag might deploy at any time, and that the clock spring, the steering wheel, and possibly the driver’s seat needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 170,000.

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.
