2023 Nissan Altima

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.

During a traffic incident on March 26 2026 I was the driver of the 2023 Nissan Altima SL and I suffered unnecessary bodily injury due to the AEB system. I was in a forward collision, the warning indicator did not go off, and the AEB may have went off after the crash unnecessarily causing major damage to my right shoulder tearing one ligament partially, one ligament completely and tearing my rotator cuff and needing reconstruction and two joints anchored. The impact of the AEB jolt went up my wrist and the force through my shoulder to cause that damage is inexplainable since I was at a complete stop and maybe only one car length away from the other car. I hit my face on the steering wheel. Airbags did not deploy. My son in the passenger seat suffered a concussion as did I. The only thing we can find that could cause this amount of damage is if the AEB decelerated after impact unnecessarily and the airbag did not deploy. That means our bodies were already moving through the impact of the crash only to have been thrust into a second unnecessarily intensely strong AEB jolt. Had the AEB not engaged, we would not have injuries. The warning system failed to activate as well. This system has gone off in error multiple times and the AEB had also engaged several previous times in error when backing out of my driveway. I did not know that it could be an error with the system until I started researching my injuries and learned that this is an issue with this model of Nissan.

I purchased my car earlier this year. Paid in full. After having it for about 3 months I had to get a new battery. Now, about 2 months later I’m having to get a new alternator. A licensed car mechanic purchased the battery and put it on. The alternator, I went to the Nissan dealership and they told me it was the alternator. Never any lights or warning lights or labels, with battery I had to boost it, with Alternator it just started making a loud sound. I was afraid if mind and willows(my 6 year old) safety, driving and breaking down on the road, so I took it to Nissan to run a test on it. With no warnongs and this loyd noise i was freaked out. The altinador cost $901.00, just for the part, with a 2 week back order.

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.

The back up camera displays white while the lines to back up are present.

P235 /40 R19 92V tires came with 2023 vehicle purchase. Two years following purchase, there are 2 large sidewall cracks at 32,000 miles for the front driver side tire even though the manufacturer mileage warranty is 70,000 miles. One out of four tires exhibiting this issue. Find this to be a huge safety concern as I was unaware of the cracks and there were no air leak/pressure issues sensed.

A car slammed on brakes in front of me and I hit the brakes but my car still hit the other car messing it up pretty badly. No one was hurt but the car has stopped automatically before, it’s like the sensors couldn’t tell I vehicle had stopped or was even in front of me.

THE AUTOMATIC EMERGENCY BRAKING (AEB) SYSTEM WITH PEDESTRIAN DETECTIONB WARNING LIGHT COMING ON IN MY CAR. NO, I DONT FEEL MY SAFETY WAS AT RISK AT THAT TIME NO, IT HAS NOT BEEN REPRODUCED OR CONFIRMED. WE DID TAKE THE VEH TO NISSAN OF GREENVILLE, TX AND WAS TOLD THERE WAS NOTHING THEY COULD DO ABOUT IT SINCE THE LIGHT WAS NOT ON AT THAT TIME AND DWAS TOLD THE SENSOR MIGHT BE DIRTY, OR THAT THE SUN "HIT THE SENSOR, CAUSING IT TO GO OFF" THERE WAS NO OTHER LIGHTS OR WANRNINGS PRIOR TO THE MALFUNCTION WANRNING

This vehicle was purchased used with 10,000 miles. Since purchase we have been experience with the battery and electrical system not functioning properly. The car is not driven much, but is started daily and run for 10 minutes when it is functioning. The car shuts down and it is necessary for us to have USAA or AAA start it, they have told us there is an electrical system problem. The car was taken to Colonial Nissan dealership in Feasterville, PA for PA state inspection and to resolve this problem. We were told "the car is not driven enough and there is no problem". The car is driven a few miles daily and has shut down again. I have contacted Nissan and they said they would get back to me to resolve this problem. I contacted them on 6/20/25 and they have not gotten back to me. The car has shut down at least a dozen times requiring USAA or AAA roadside assistance, both say there is an electrical problem.

This is my second complaint on this vehicle I have brought my car back multiple times for this issue and I keep getting they have found nothing wrong I feel very unsafe driving this car it stalls frequently while I’m driving I’ve been in the middle of very busy intersections I’ve been at stop lights it’s very humiliating when a a newer car stalls all the time. I’ve gone to the stores and come out and my car won’t start it’s very nerve racking and embarrassing having a 2023 vehicle and this is the stuff I have to deal with on a day to day basis wondering if I’m going to be able to go to work or any where or be stranded some where I bought the car brand new and it has not been reliable at all I’m to the point where I feel I need to seek legal advice on this matter. Since no one knows what the issue is. Very unhappy customer not a safe car at all stalling in the middle of intersections is pretty scary

My car shuts off going down the road happens randomly it happened in July of 2024 and in November 2024 no warning lights came on it just shuts off I have not had my car looked at yet but I do plan on taking it to a dealer

backup camera fails consistently backup camera screen goes grey. it is dangerous because you cannot see behind or to the side when backing up. it has been to the dealer and they claim they cannot replicate the issue. the problem is more consistent now and it is out of the 36000 mile warranty. the camera system is now failing daily. no warning lamps. the vehicle also has a no start condition, and it won't detect the key fob intermittently resulting in me being stranded 3 times. also taken to the dealer and the problem could not be replicated. the camera problem does not seem to be affected by weather conditions wet or dry hot or cold the problem started at approx. 10000 miles took it to the dealer at 34000 miles now i have 48000 miles car is 2 years old.

My car has 33,214 miles on it. For no reason the alternator DIED ON IT. There was no warning on the dash of the vehicle. So the computer inside the vehicle did not give a warning that the electrical system for the alternator had died or that the battery had died. There’s no corrosion. There’s no shorts. I checked the fuses myself. This car has two sets of fuses one leads to the battery. The other one is for the infotainment center inside the vehicle. It’s not been tampered with. So there’s an issue with the computer system and how it registers errors to the dash of the vehicle also. That is a software issue. Whenever there is an issue with the engine, the computer system is supposed to register that to take it to get service or whatever. No warning ever came. An alternator is supposed to last 100,000 miles or better on a vehicle. So I’m stranded. I don’t have the tools to change out an alternator. But Nissan wants to collect my data to sell it. The tow truck just got here to give me a jump, so it’ll probably be towed to Nissan tomorrow to get it fixed. And it looks like a like I like she has to have a full bed for a tow. She can’t be towed like that. She has sensors and I don’t want her hurt.

Backup camera for no reason failed. Screen is bright white when in reverse. Occasionally when the car is cold and reverse is quickly selected image will be seen for a few seconds then fades to all white. Backup camera only. Car has less than 8k miles no accidents.

I took my car into the dealer to ask a question. Upon arriving I tried to open the drivers door after I turned the ignition off to exit the car and the drivers door would not open. The service man tried to open it from the outside with the same results. Finally it opened. It had done this before but I always forgot to tell them when I was at the dealership. The passenger door had done the same thing. The dealership ordered new front door latches for both front doors and replaced them. Yesterday I entered the drivers door to back the car out of my daughter’s garage. I was again unable to get out of the car. The door would only open part way then get stuck. Once outside the car I tried to re-enter the drivers door to leave and I could not get the drivers door open. This is a safety issue. It is scary when you cannot get out of your car.

Right rear Seatbelt was not connected to car frame at bitter end. Bolt and seatbelt end were tucked behind seat cushion vice bolted and torqued to support bracket. Discovered upon first use of rear passenger seat.

I was riding down the highway when all of a sudden I hear loud bang, the rear windshield, completely shutters, spontaneously out of nowhere. This is a huge safety concern as I could have easily caused or been involved in an accident due to what occurred I have looked up on other forms where this has happened to other Nissan owners. This can also be inspected by service center employees as well as document documented by the police. Be careful as there are no warning signs if or when this may occurred to your vehicle
