2018 Nissan Altima Problems

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

Brake switch failure contributed to intermitten braking resulting in near crashes

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

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.

The contact owns a 2018 Nissan Altima. The contact stated that while driving from a stop sign and depressing the accelerator pedal, the vehicle hesitated to respond as intended. The contact stated that while attempting to start the vehicle, the vehicle was jerking for several minutes. The check engine warning light was illuminated. The vehicle was taken to a local dealer but was not diagnosed since the check engine warning light was not illuminated. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

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.

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 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)

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.

The contact owns a 2018 Nissan Altima. The contact stated while driving approximately 35 MPH, the hood latch inadvertently unlatched, and the hood raised up and fell onto the windshield and cracked the windshield. The contact was able to drive a short distance to the residence. The vehicle was towed to an independent mechanic where the windshield was replaced. The contact stated that she was informed by the Insurance provider that the VIN was included in NHTSA Campaign Number: 20V315000 (Latches/Locks/Linkages); however, the contact never received the recall notification letter. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 59,000.

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.

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.

NISSAN ALTIMA TORQUE STRUT MOUNT AND PASSENGER SIDE MOTOR MOUNT FAILURE

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?

While I was driving my power steering went out completely on the interstate right when I went to turn almost causing an accident where I could have been severely injured or injured others around me. Prior to the failure my front vehicle obstruction light has been coming on and off multiple times while driving but other than that no warning signs of power steering going out.

SEVERAL TIMES WHILE NORMAL DRIVING AND NOTHING IN ROADWAY THE DISPLAY WILL SAY UNAUTHORIZED OBJECT IN VIEW AND THERE'S NOTHING THERE HAPPENS SEVERAL TIMES A DAY SCARES ME AT FIRST CAUSE I THINK SOMETHING WRONG AND TAKES 10 MINUTES FOR DISPLAY WARNING LIGHT TO TURN OFF

NISSAN ALTIMA TORQUE STRUT MOUNT AND PASSENGER SIDE MOTOR MOUNT FAILURE

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

The driver seat airbag seems to be disabled. I am seeing a airbag warning light for driver airbag in the dashboard. The dealership doesnt see to car and a 4yr old car should not have airbag issues when it has never been in an accident. The driver seat seatbelt also seems to be disabled, if i step on the break the seatbelt doesnt seem to be gripping me its still freely moving which it shouldnt be. This is a big safety issue and seems to be a manufacturing defect.

I was rear-ended in my car while at a red light. The car hit me 35 mph plus., Pushing me into the Tahoe in front of me. My shoulder strap driver side DID NOT restrain me and NONE of the air bags deployed. I flew forward towards the steering wheel and dash. Do to me being very short I didn't get hurt, just stiff neck, shoulders. The collision company who did my work stated that the seatbelt should have restrained me and at least 1 airbag should have deployed. I contacted Nissan and I was told that the air bags and seatbelts are only suppose to work in a roll over to prevent from being thrown from the vehicle and that the airbags and seatbelts are working properly. Nissan never offered to check to make sure that the safety components are working properly. There were no warning lights on before or after the accident. Over $10,000 worth of damage was done.

The contact owns a 2018 Nissan Altima. The contact stated that while the vehicle had been parked in the driveway for three months, however, a crack developed on the windshield. The contact stated that no object had impacted the windshield to cause the crack. The dealer and manufacturer were not made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was 12,846.

LOW BEAM HEADLIGHTS ARE NOT EFFECTIVE IN SEEING AT NIGHT. KNOWN ISSUES IN NISSAN ALTIMA MODELS WHERE HEADLIGHT ASSEMBLY REFLECTIVE PARTS BECOMES FOGGY AND DISTORTED/MELTS DUE BUILD UP OF HEAT FROM HALOGEN LIGHT BULBS LOCATED IN THE ASSEMBLY. CREATES DANGEROUS ROAD CONDITIONS NOT ONLY FOR THE DRIVER BUT FOR OTHERS AS WELL. NISSAN CONTINUES TO IGNORE THE ONGOING ISSUES AND HAS YET TO ISSUE AN ALTERNATIVE TO CORRECT THE PROBLEM.

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.

The rear trunk latch will not close and latch so the trunk is left wide open

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 contact owns a 2018 Nissan Altima. The contact stated that while driving approximately 50 MPH, the vehicle suddenly lost motive power without warning. The contact coasted to the side of the road and was unable to restart the vehicle. The vehicle was towed to the dealer who diagnosed that the transmission failed and needed to be repaired. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 69,000.

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.

WHILE DRIVING HOME AND JUST ENTERING MY NEIGHBORHOOD, I NOTICED A LOW TIRE WARNING ON MY DASHBOARD. I LOOKED AT THE PRESSURE AND THERE WAS APPROXIMATELY 26 POUNDS STILL IN THE TIRE AND THE CLOSEST PLACE TO FILL UP WAS AT MY HOUSE. WHILE APPROACHING A RIGHT TURN IN THE NEIGHBORHOOD AND BECAUSE OF THE WINTER WEATHER CONDITIONS OF SNOW AND ICE ON THE ROAD, I SLOWED DOWN TO A CRAWL AND APPLIED MY BRAKE PRIOR TO AND WHILE TURNING. WHILE IN THE BEGINNING OF MY TURN, I INSTANTLY REALIZED THAT I HAD NO CONTROL OF MY CAR AND I SLID INTO A SNOW BANK ON THE SIDE OF THE ROAD. THERE IS NO DOUBT THAT I WAS GOING TOO SLOW FOR MY CAR TO SLIDE. I WAS RIGHT DOWN THE ROAD FROM MY HOME SO I CONTINUED HOME THINKING I COULD NOT HAVE HAD SIGNIFICANT DAMAGE; HOWEVER, AS I WAS DRIVING, MY RIDE DID NOT FEEL NORMAL EVEN THOUGH I WAS TRAVELING AT A VERY SLOW PACE. WHEN I GOT INTO MY GARAGE, I FOUND MY TIRE WAS COMPLETELY FLAT AND THE DAMAGE WAS SIGNIFICANT TO MY FRONT DRIVER SIDE BUMPER. THE NEXT MORNING I REMOVED MY TIRE TO SEE WHERE THE PUNCTURE WAS AND IF IT WAS REPAIRABLE. UPON FURTHER INSPECTION AND WHILE FILLING THE TIRE WITH AIR, I REALIZED THERE WAS NO HOLE IN THE TIRE BUT THERE WAS A FAST AIR LEAK AT THE RIM. ON MONDAY MORNING, FEBRUARY 15, 2021 I BROUGHT MY TIRE IN FOR REPAIR. I HAVE NO DOUBT THAT A DEFECT EXIST IN MY TIRE AND WHEN I LOOKED TO SEE IF THERE WAS A RECALL, I REALIZED THAT THE SAME TIRE I HAVE ON MY VEHICLE IS SHOWN ON THE RECALL LIST BUT IT IS FOR 2019 TIRES AND NOT 2018. PLEASE LOOK INTO MY COMPLAINT AND CONCERN. IF I HAD BEEN TRAVELING ON A HIGHWAY, I COULD HAVE EASILY BEEN KILLED. I HAD NO CONTROL OVER MY VEHICLE WHEN THE AIR WENT OUT AT THE RIM. MY TIRE IS A CONTINENTAL CONTIPROCONTACT P215/60R16 94T ALL SEASON DOT 6YX8 3YD 2018. THE TIRE SAYS MADE IN SLOVAKIA. OTHER NUMBERS ON THE TIRE WERE 3-979 84579 230385 E4 0231843.

I purchased Milestar tires model ms932 sport in 2021 size 235/45/18. In Jan.2024 my tire pressure indicator light came on and I pulled over and changed the tire to my spare and took the tire to my tire dealer and it had to be replaced with another tire due to the sidewall separating on the inside of the tire. The tire was on the front of the passenger side of the car. There was still plenty of tread wear on the tire. About a month later the same thing happened to another of the milestar tires. This time it was on the front driver's side. When this happened to the second tire, I took the car into the tire dealer and upon inspection it appears to be that the tires are going to do the same thing on the other two.
