2018 Nissan Altima Air Bags

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.

See attached document for complaint.

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. This defect also endangers passengers and other road users in the event of an accident. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The defect was confirmed by Northlake Kia on August 29, 2025 during vehicle inspection. The dealership stated that the part is defective and must be replaced immediately. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by Northlake Kia, an authorized Nissan service center. The manufacturer (Nissan Consumer Affairs) has been notified but has not yet provided a resolution or replacement part. There has been no involvement by police or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. and before thats what prompted me to bring the vehicle in to be serviced. Upon inspection at Northlake Kia on August 29, 2025, the dealership identified the driver airbag module defect. The airbag warning light was illuminated on the dashboard, indicating a malfunction in the airbag system.

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 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’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.

On February 7, 2022, my daughter was driving her 2018 Nissan Altima and was involved in an accident. It was a head-on collision, but the airbags didn’t deploy and, as a result, she was thrown forward into the steering wheel which caused severe trauma to her head.

OCS system is faulty causing the airbags for the passenger to disengage. I am out of warranty for mileage at the time of the problem by 6,000. The car was 3 years old and it is an on going problem again. OCS switch showing improper voltage and cannot be reset unless the factory mechanic does the reset which holds me, the owner, responsible for the diagnostic fee. Additionally, the faulty parts may have to be replaced at my expense as well if it turns out to be a more than a software glitch. There has been recalls for 2016 and prior for the same issue and a recall for 2018 models is happening again.
