2018 Nissan Altima Owner Complaints

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.

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.

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

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.

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.

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 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.

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.

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.
