Nissan Altima 2018 — Problemas reportados

While operating my 2018 Nissan Altima on September 19, 2026, at approximately 9:20 a.m., during daytime highway traffic, the vehicle suffered a sudden and complete loss of propulsion, leaving me entirely immobilized on a highway ramp with no ability to accelerate or move out of danger. I was stranded in an extremely hazardous location with vehicles, including large commercial trucks, traveling nearby at highway speeds. I feared for my life because I had no way to move my vehicle to safety or protect myself from a potential collision. The situation was so dangerous that a State Trooper with Highway Patrol had to intervene and arrange assistance to have my disabled vehicle removed from the highway. Had Highway Patrol not arrived, I genuinely believe I could have lost my life. This was not a minor inconvenience or an ordinary vehicle breakdown. It was a potentially fatal safety incident caused by the vehicle's sudden and complete inability to move. Following the incident, an independent repair facility inspected the vehicle and determined that the transmission requires replacement. The diagnostic findings included P17F0 (CVT Judder), P0776 (Pressure Control Solenoid B performance/stuck off), and P2813 (Pressure Control Solenoid G control circuit range/performance). Before the complete failure, the vehicle had experienced hesitation, vibration, and difficulty accelerating. I am extremely concerned that this type of transmission failure can occur suddenly while a vehicle is operating in active highway traffic, potentially resulting in a serious or fatal collision. I am requesting that NHTSA investigate this incident as a significant vehicle safety concern and determine whether a safety-related defect exists in the CVT transmission system of the 2018 Nissan Altima. I have supporting diagnostic documentation and towing records, and the vehicle is available for inspection.

The passenger‑side airbag warning light first appeared within the first year of ownership. During that visit, the dealership did not repair the defect. They only reset the warning light and told me it was not a problem. No diagnostic documentation or repair explanation was provided, and the underlying issue was not addressed. The warning light returned in April 2026, showing the same unresolved defect. The dealership stated the repair would cost approximately $2,000 and said neither the Certified Pre‑Owned warranty nor the extended warranty would cover the airbag system. This contradicts the nature of the failure and the prior visit, where the defect was dismissed instead of repaired. This is a repeat failure involving a federally regulated safety component. The airbag system may not deploy properly, and the vehicle has been operating with an unresolved safety defect since the initial visit. The problem has been confirmed by the dealership, and the warning lamp continues to illuminate. The defect has not been corrected by the manufacturer, despite multiple attempts to seek assistance.

While driving at regular road speeds, the vehicle suffered a catastrophic safety component failure. The primary hood latch disengaged, and the secondary safety backup latch failed to catch or secure the hood. This caused the hood to violently slam completely open against the front windshield without warning, instantly and totally obscuring forward vision while the vehicle was in motion. This failure created an immediate, extreme crash risk for the vehicle occupants and other drivers on the road. Prior to the incident, there were absolutely no warning lamps, dashboard messages, or audible symptoms indicating a problem with either latch mechanism. The failed latch mechanism and the damaged vehicle have been safely preserved and are fully available for a complete inspection upon request. At this time, the vehicle has not yet been inspected or reproduced by a dealer, independent service center, the manufacturer, police, or insurance representatives, as the failure just occurred. This vehicle model and year are direct subjects of NHTSA Recall Campaign Number 20V-315 for this exact dangerous secondary latch defect, and the vehicle suffered the precise catastrophic safety failure detailed in that federal manufacturer safety bulletin. ]

I am currently experiencing CVT failure as of I have filed a case with the nissan consumer affairs unit, case number 56846043. I was advised that even though there was a class action suit in 2022 for CVT issues, my CVT Warranty Extension expired on 12/09/2024 for this class action suit. I purchased the car in May of 2025. The dealership failed to mention the class action suit or there were problems with the transmission. Since this is a well known issues, I am requesting help with the cost of repairs.

So I have the 2.5L QR25DE engine with the exact exhaust failure from campaign PC717, and I need Goodwill Assistance because the part failed identically.

Transmission stopped working on me in the highway cvt code that comes up is P17f0 was in the highway going 45 mph then dropped 5 mph very dangerous. Almost crashed

The warning light on the dash is indicating that there is a problem with the airbag. I took it to a Nissan Dealership and was told that the side airbag needed to be replaced. I was quoted $3,241.41labor only. I was told there was no recall. I certainly don't want there to be a collision and it doesn't deploy as it should. So I would like to report this issue in the event this has happened to others.

The problem is I have that transmission in my car that nissan was sued for . Yes I received a extended warranty 85 months or 85,000 miles . My transmission started going out as soon I rolled over 85,000. Dealer told me the warranty was no good. Now it's sitting in the yard. All I can do is make the payment. Not only am I making payments but I have to keep insurance and tags for a car I can't drive!!!! I sent nissan an email but I get no response! I desperately need help! My fiancee dream car turned into a nightmare. Thanks! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In 2022, there was a recall on the hood latch system. At that time the dealership was able to spray a substance on the latch and close out the recall instead of replacing the latch. Now my car is having issues with the latch that should’ve been replaced from the start. Therefore, the solution during the recall only prolonged the issue and did not fix the issue. There hasn’t been an accident, as of now. However, this could cause an extreme situation and put everyone’s safety at risk.

While driving my Nissan Altima 2018 on Sunday 2-1 the indicator light came on. I looked it up in the manual to the car and it stated it was something with the air bag. I took it to the Larry Miller Nissan Mesa AZ. Wednesday, 2-4. According to them I was told the light indicated the air bag would not deployed if I were in an accident. That is life threating. This is report I got from them: They checked for codes found code B0020-13 store din air bag followed the diagnosis procedure as per the ESM to inspect the air bag seta harness to be okay connected first step is to replace the LH side air bag module as per the DTC. They told me it would cost $3,247.44 to fix. I know there was a recall on the air bag for my make and model but unknown to me when it was posted. My car have always ran like a new vehicle to this day until this happen. It should be considered a manufacture issue and should be repaired by the manufacture.

Didn't know what the list this one but at a certain speed on the highway the hood latch comes loose unlocks, and my backup camera All of a sudden doesn't always work, sometimes the screen is completely black... Also the sensor that tells you that a car is too close to you keeps turning itself off and then when you check the radar sensor to make sure that it's clear of debris there's no debris but yet this thing just keeps turning itself off while you're on the highway or local road... I will list when the first problem started happening and then we know when the other ones start happening consecutively afterwards.. electrical issue front passenger door will not open automatically Putting my passenger at risk

NISSAN ALTIMA TORQUE STRUT MOUNT AND PASSENGER SIDE MOTOR MOUNT FAILURE

See attached document for complaint.

The contact owns a 2018 Nissan Altima. The contact stated that while driving at an undisclosed speed at night, the halogen headlights failed to function as intended and were dimmed, which reduced the visibility of the roadway. There was no warning light illuminated.  The vehicle was taken to a collision center, where the headlight assembly and bulbs were replaced. The vehicle was repaired. Upon further investigation, the contact learned that the headlights on Nissan vehicles were experiencing failure due to a delaminating reflector defect. The contact learned that the heat from the halogen beams was causing heat damage to the reflective surface. The manufacturer was not made aware of the failure. The failure mileage was unknown.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The driver seat airbag module is defective and requires replacement. It is available for inspection at Northlake Kia or any authorized Nissan service center upon request. 2. How was your safety or the safety of others put at risk? The defective driver seat airbag module may fail to deploy properly in a collision, placing the driver at serious risk of injury or death.

My Nissan Altima's power door locks failed making entry and egress sometimes impossible. While the key will unlock the driver's door, rear seat passengers have been unable to exit the vehicle without assistance due to the door being locked. Premature power door lock actuators in Nissan vehicles is reportedly a very common problem according to my research.

Suddenly airbag light has steady on when start engine. Scanner shows has failed code L4 and failed to reset.

I purchased this vehicle last month from Anderson in cockeysville, Md. last week the airbag light came on. I was able to take it to them today 9-15-25 where they at first told me I was over the 1,000miles warranty so I’d have to deal with it on my own. After speaking with a manager, he agreed to take it to Nissan to get a determination.

The headlights on my 2018 Altima SL are INCREDIBLY dim. I have tried two different LED manufacturer's bulbs with the same result. It is beyond dangerous to drive my car at night. Sadly, my floodlights are FAR brighter than my low beams. There are countless complaints for this issue over the past few years. It sounds like their solution was less than desirable for most customers. This should be an actual recall to ensure that the Hundreds of thousands (probably more) of the 2013- 2018 Altimas on the road are safe for the drivers as well as the cars around them. This issue is ridiculous and MUST be corrected.

The contact owns a 2018 Nissan Altima. The contact stated that the headlights on the driver's and passenger's side of the vehicle had identical stress fractures. The fractures allowed water to enter the headlight housings. The dealer was contacted and confirmed that the headlight assemblies needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case for the failure. The manufacturer informed the contact that the headlight assembly replacements were not covered under warranty. The failure mileage was unknown.

There is a recall for altimas from years 2019-2021 with an issue where the engine will not start after the battery light on the dashboard comes on. After a few minutes the car will start up and ride like normal. This also happens in the 2018 model of the altima. This happened to us multiple times. The battery is good, and there is no reason for the engine not to start right aqay. Why is there no recall for the 2018 models?

The driver's side door lock actuator stopped working around June 2024. Haven't replaced it yet, but bought another part. Read where others are having same issue. Just in the last couple of weeks, around June 15th, 2025, my rear driver's side door actuator stopped working as well. I have to crfrawl in from the other side and unlock the doors. Safety issue since the doors do not lock or unlock.

Anytime I pull my hood release, my hood never opens & I hear no click .

The airbag light in the dashboard always stays lit. It has been worked on at the dealership multiple times and they get it to go out only for it to come back on. It’s concerning not knowing if there is a problem with the airbags itself. This has been on going for years. It started around when my car had 34000-35000 miles on it.

I’ve had to replace the break sensor a few times and it’s unusual… My check engine light came on and it reads the code for the catalyst converter.., the auto part store saw a recall on this for my make and model but not seeing it here . The code was cleared and hasn’t came back on yet but I’m anticipating it will .. these two issues need to be further looked into please

It seems to be the transmission intermittently. I'd stop, push down on the accelerator and would go like a few MPH. Then it would lunge forward and I'd have to slam on the brakes to avoid hitting the vehicle in front of me. The other thing was it didn't seem to shift from first gear - I ended up redlining it at 7000rpm when only going 45mph. I've read that there is a problem with Nissan cars and the CVT. In answer to your questions: You can inspect it. At a stop/light, I'm always afraid the accelerator will start out slow and then lunge forward and eventually I'll hit another vehicle. The dealer couldn't reproduce the issue after having the vehicle 6 days. After 3, they "re-programmed" as the service manager said it was out-of-date and that doing so may fix the problem. They then tested for a further 3 days and couldn't reproduce it. Vehicle has only been inspected by the local Nissan dealer. There were no warning lights or messages before or after these incidents.

Took car for inspection check engine light on will not pass mechanic said same issueue as recall PC716. Said was under recall nissan recall does not include the vin so would not repair need to add vin to recall since it is same issue. Can not drive until repaired.

I’m getting an Air Bag warning light showing up on my dash. i took it to the Nissan dealer and its error code B0020-13 which comes up as a Left seat side air bag open error. Apparently the wiring going from the connector under the seat up to the side air bag is intermittently opening up depending what position the seat is in. Nissan said the entire top part of the seat needs to be replaced, very expensive, $2,500.00 to $3,000. This is a big safety problem since this is a common problem with this model from all the research I have done. This is obviously an engineering problem with how the cable is ran or quality of the cable and should be Nissans responsibility not the owner of the vehicle.

The airbag light appeared on my dashboard in late December. On 1/8/25, I took it to Auto Nation Nissan in Tempe to have it checked. They determined that the driver's side seat back needed to be replaced. That is where the airbag sensor is located. As of today, 3/14/25, they still do not have an ETA for the seat back. I have been driving for almost 3 months now without the airbags working. I also contacted Nissan corporate, and get the same response - they can't get an ETA for the seat back that is needed.

Shortly after purchasing my 2018 Nissan Altima (new), there was a recall concerning the passenger side airbag. I took the car to the dealer and had it serviced. Months later, there was a second recall and I took it back promptly; however, the dealer said that nothing was wrong. It was already serviced. I indicated that I had received a second notice. Some time passed, and the same airbag light indicator came on and stayed on. I took my vehicle back to the dealer. This time, they wanted to charge me thousands of dollars. I indicated that this is the same problem from the beginning and I was going to file a lawsuit. The dealer claimed to have fixed the sensor and told me it was a complimentary charge based on "goodwill". The same sensor light is on again. I have had no accidents and I have not had my car serviced for any electrical issues. It was inspected and passed with a warning to get the sensor taken care of. The original dealer has now sold to another Nissan dealer. I need to be sure that I am safe should I have a situation where the passenger side airbag needs to deploy. This is not fair to me. I have never bought a used car and this is the first car I have continuously had unresolved issues with. Please advise.

Vehicle turned off on a red light. The vehicle was on drive, my foot on the brake waiting for the green light, the car then died while waiting. Check engine light is on.

For the transmission I was driving at normal speed in the freeway when out of no where the car started to jerk and lost power I almost got hit by the car behind me it was a traumatizing experience for me and my son I haven’t gotten my car to get repaired because as a single mother it is very hard on me and with the suspension it had been making loud squeezing noise from my rear suspension and it has gotten worst now it’s embarrassing to be driving my daughters father in law also had an Altima and it had the same suspension issues

My back doors do not lock with the FOB or the interior door lock/unlock button. I have to manually unlock and lock my rear doors. This is a defect that Nissan is well aware of and seems to not care. My car only has 63,000 miles on it.

Cvt transmission, yes its available for inspection. Loss complete horsepower on highway after it jerked. Kids in car at time. Took it to the autozone to get printout after check engine light came on, then took it next morning to dealership which did confirm that my transmission is in failure. Have printout confirming my concern. No lights were on I had just an oil change before getting on the highway.

I want formally lodge a complaint regarding a serious issue with a 2018 Nissan Altima that I purchased from a Nissan dealership on [XXX]. The vehicle, which had 107,000 miles at the time of purchase, has exhibited a critical failure. On [XXX], while I was accelerating to change lanes in rush hour traffic, the car began jerking and suddenly slowed down. This malfunction nearly resulted in a dangerous collision with an 18-wheeler and caused me to be run off the road. This incident could have been catastrophic, and it deeply concerns me, especially since this vehicle was intended for my daughter's commute to and from school. Following this, I had the car towed to the Nissan dealership and was informed that it requires a new transmission. I am shocked to learn that the cost to replace the transmission is $6,200. This is particularly distressing given that I purchased the car less than four months ago and was unaware of the known issues with the CVT transmission. It is unacceptable that vehicles with faulty transmissions are still being sold without adequate warning or extended warranties. Nissan should be required to provide clear disclaimers about potential transmission issues before a sale. The lack of transparency and the high cost of repairs are deeply troubling. Given the severity of this situation and the potential risks involved, I believe that Nissan should take immediate action to address these concerns. The warranty should be extended, and there should be clear warnings provided to potential buyers about the risks associated with the transmission. The current lack of empathy and action from Nissan is disappointing and unacceptable. I urge you to review this situation promptly and provide a satisfactory resolution.

UNKNOWN air bags lights turn off and on on the passenger side. No air bag light remains on all of the time of the driver side

Air bag dash warning light came on. Brought to dealer. They"fixed". Light came back on few days later. brought back to dealer. They said drivers side seat frame with air bag needs to be replaced. they ordered part & said 2 week wait. Called dealer back 2 weeks later & they said part not released by Nissan. Called Nissan consumer affairs. They informed me they have no ETA when parts will be available/shipped. Been about 2 months since first contact with dealer & have no idea if/when will be repaired. See recalls on older Altima & am wondering if this is an issue Nissan is not addressing.
