Nissan Altima electrical problems

I am filing this complaint because the locking system on my 2019 Nissan Altima has been malfunctioning for a few years, and it has now become a serious safety issue. I first noticed that my back doors and my front driver-side doors would not lock or unlock when using the remote or the button inside the car. This is very concerning because it means my car is often unsecured when it should be locked, and there are never any warning lamps or messages to let me know the system failed. I have to manually lock and unlock the doors myself just to get them to work, which has happened multiple times while my kids were trying to exit the vehicle. The problem has recently gotten worse. Last week, I had an issue where the door would not open at all because the latch stayed engaged even though the door was "unlocked." I had to pull the manual lever multiple times before it would finally open. This constant locking issue is a major risk because it could prevent us from getting out of the car quickly in an emergency. The vehicle and these components are available for inspection, and I am taking the car to Nissan tomorrow to have the problem confirmed and inspected.

The driver’s seat heater malfunctioned and produced excessive heat while activated during normal vehicle operation. The heat became extremely intense at a low temperature and resulted in burns to the driver’s midsection, lower back, and upper buttocks. I, the driver sustained physical injuries including burning sensations, skin irritation, and visible discoloration marks in the affected areas. The excessive heat occurred without warning and created a safety hazard to the driver while operating the vehicle. There were no warning lights, messages, or alerts indicating a problem with the seat heating system prior to the incident. The vehicle has not yet been inspected by Nissan Motor Corporation Consumer Affairs. An inspection appointment originally scheduled for February 24, 2026 was rescheduled to March 12, 2026. The vehicle and seat heating components are available for inspection upon request.

Passenger back locks stopped working first. Then driver side back locks. Now both driver and passenger front locks will not lock/unlock automatically. This is scary when not being able to get in/out of vehicle for an emergency. I have reviewed multiple complaints and it appears this is a very common Nissan problem that needs to be addressed before it becomes a bigger safety problem.

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.

I changed the Air Mass Flow sensor and it’s still showing the check engine light on my dash board and giving me the same code after replacing it brand new. My brakes sound horrible after replacing both sets of brakes, front and back. The Foward Collision Warning sensor did not respond in a timely matter, resulting in a minor fender bender.

This is my second Altima I bought. A 2016 and a 2020. Both vehicles had issues where the car door wouldn't open from the inside or outside due to the lock system. If my car is "locked" and I go to open the drivers door,. it sets off the theft alarm system. These issues cause major issues because if I get into an accident and am not able to open the car door I could possibly die from not being able to get to me fast enough, sitting too long, etc the possibilities are endless. Not to mention I get up pretty early sometimes so to hear a theft alarm at full maximum volume is frustrating to say in simple terms. Other issues include the volume on my car will randomly turn to max volume or turns off. Essentially an error electronically that affects numerous aspects and integrity of the vehicle itself.

Every time I put the breaks on or go over any kind of speed bump, it bounces and sounds like warn out bed springs. Out of nowhere The volume on my radio will turn up extremely loud. Its happened more than a handful of times while driving and it scared me to the point of having to pull over to gather myself. Some days it doesn’t work at all. The past 3 months, My front passenger window gets stuck and won’t go up without me turning the car off then back on and still at times won’t work. I’ve had no choice but to leave the window down more than enough times and putting plastic over it until it decides to work again. The engine shakes and it feels like the transmission is about to give.

MY 2024 Nissan Altima, with approximately 13,000 miles stalled while driving in 10 degree Fahrenheit weather with snow on the road. My speed was around 45 MPH. The vehicle immediately stalled and all the lights on the dashboard went on. The warning flashed something about an engine error. The brakes seized up while in snowy weather and with cars very close behind me. Easily could have caused an accident and was a pretty scary event. The car is maintained well and have very low mileage and is taken care of well. I slowed down and then another error screen popped up saying to immediately take care for service. While I was attempted to slow down with brake pedal super hard to push; I attempted to put car in neutral with my hazard lights on by now. Car started again while I was coasting about 20 mph, with engine light showing. I immediately took it to the closest dealership to me for service and left it there. This is completely unacceptable behavior for a new car of this type and I never experience anything ever like this with my old 2012 Nissan Altima. This could have caused a very bad accident had I not been driving and my wife or something else not as calm as me were to be driving. I suggest investigating this because I have read about recalls for this type of thing on previous models of Nissans. Currently vehicle is parked at dealership for service on 1-24-2026.
