2020 Nissan Altima Electrical System

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.

All 4 door lock actuators have failed, no warning lamps indicating this issue, first appeared in 2024. Car has been broken into as a result

My driver door does not lock and unlock automatically. This poses a risk because my door remains unlocked when I think that it is locked. Also, I have to go in through the backseat of the passenger seat in order to get in my car posing risk of someone coming up behind me. I had the back actuators replaced a couple of years ago, I asked about the front since the car was still under warranty and I was told they would not replace them since they were not acting up at the time. I was told at one point it would be around $800 to have the front ones repaired. The lock has been working intermittently probably for the last year and a half, but have now completely quit working.

Locks no longer work with key fob or button within car and sometimes even takes multiple attempts to manually unlock. This poses a danger if needed to enter or exit the car in a hurry.

My 2020 Nissan Altima Door actuators are all currently broken. The doors will not unlock with the fob and have to be manually unlocked. This can cause a huge safety issue if they are unable to be unlocked.

The brake switch keeps coming loose making it difficult to start the car when pressing the brake down. When the switch is not secure, the electrical connection is lost and it is very hard to press the brake down. What if this happens in the middle of traffic? The issue also causes the brake lights to remain on and not turn off. This has to be a faulty part. My car is a 2020 and the it's too soon for wear and tear.

All 4 door actuators have gone out. I cannot lock or unlock my car with the key fob or manually with the key from the outside. The driver side door is unable to be manually locked/unlocked causing me to get locked in and out of my car randomly. Within the last month, it has gotten more frequent with the driver said. The rear doors went bad months ago. The passenger door started approximately 2 months ago and the driver door within the last month. This was confirmed by Modern Nissan in Winston Salem, NC on 06/10/2023 and I got a second opinion on 06/16/2023 who also confirmed all 4 door actuators needed to be replaced. There were no warning lights or messages.

BLIND SIDE WARNING NOT WORKING - RADAR NOT AVAILABLE DUE TO SIDE OBSTRUCTION. SEVERAL TIMES THE INSTRUMENT PANEL HAS MALFUNCTION - NISSAN CLAIMS CAR MUST BE SPOTLESS OR IT WON'T FUNCTION PROPERLY. I HAVE NEVER HAD SUCH ISSUES WITH OTHER MAKES. THE EBS WARNING LIGHTS COME ON MOST OF THE TIME WHEN TEMPERATURE DROPS BELOW FREEZING. I THOUGHT THIS CAR PROVIDED SAFETY, INSTEAD IT DOES THE OPPOSITE. NISSAN CLAIMS WHEN THERE'S SNOW ON THE GROUND SAFETY FEATURES WON'T WORK. WHY HAVE THEM THEN? MAKE A POINT OF THIS BEFORE I PURCHASE. I WASHED THE CAR AND IT BLIND SIDE DETECTOR STILL WON'T WORK. IT WOULD BE SAFER TO PRODUCE A CAR WITHOUT SUCH FEATURES SO I DON'T GET DISTRACTED BY FLASHES ON THE INSTRUMENT PANEL. SOMETIMES THE EBS WARNING GOES OFF WHEN STOPPED SOMETIMES WHEN DRIVING. ALL OF THIS STARTED OCCURRING IN LATE NOVEMBER 2019 WITH ONLY 500 MILES ON THE CAR. IF THE TEMPERATURE IS ABOVE FREEZING THE EBS WARNING STAYS OFF BUT THE BLIND SPOT WARNING HAS NOT WORKED IN 4 MONTHS. I WAS AT THE DEALER TODAY (3/26/2020) AND HAVE TO RETURN TOMORROW.
