2020 Nissan Altima Electrical Problems

I currently own a 2020 Nissan Altima with 49,186 miles and I am reporting a recurring power door lock failure. This vehicle was inspected at the Nissan of Cumming location this morning to confirm the issue. Three of the passenger-side door lock actuators have failed within a short period of time. The two rear door locks stopped working at the same time, and approximately two weeks later the front passenger door lock also stopped working. The driver's door has started to not unlock when turning the car off where it normally did up until recently. The affected doors do not respond to the interior power lock/unlock buttons or the key fob. When attempting to lock or unlock the doors electronically, I can hear the actuators attempting to operate, but the doors do not actually lock or unlock. The doors can only be locked or unlocked manually. This failure affects multiple doors and appears to be a premature component failure given the vehicle's mileage. A malfunctioning power lock system could create a safety concern if occupants are unable to quickly secure or unlock doors during an emergency situation or if electronic access is needed. I am requesting that the NHTSA investigate whether there is a broader defect involving door lock actuators or the power door lock system in 2019 - 2020 Altima vehicles. I have also submitted a case with Nissan Affairs. The case number is 56942179.

Both passenger-side and driver's side rear door lock mechanisms ceased working. They do not work when attempting to lock/unlock the doors from the inside controls in the front seat. These doors also do not lock/unlock when using the remote key fob either. Both rear doors have to be lock/unlocked manually from the inside of the door.

All four of my door lock actuators have went out without warning. This has caused stress and frustration due to not having the correct access to get in and out of my vehicle. The doors would not lock or unlock by pressing the buttons on the door or on the key itself. This has also caused a big safety concern. Being able to not open my car door is dangerous and could potentially hurt myself or others. I have contacted Nissan and they stated that there were not any recalls on my vehicle but I was suspicious since all lock actuators went out around the same time frame. I have paid to get 3/4 lock actuators replaced out of my own pocket with 1 lock actuator still not fixed. I was not made aware of the lock actuators failing and didn’t know that this was a problem a lot of other people were experiencing as well.

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.

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.

3 out of 4 of my doors have to be locked and unlocked by hand instead of using my Nissan key button to unlock my car. 3 of the motors are bad or it's some kind of electrical issue that goggle says is common in 2019 to 2020 Nissan Altimas. I feel like I shouldn't have to pay out of pocket myself to get this fixed if it's a noted common issue on goggle.

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.

Windshield Wiper Fluid Reservoir sensor going on even when reservoir is full. Gives drivers a warning light which is very distracting. If you go on line, this appears to be an extremely common problem that Nissan has not addressed. This can lead people to not know if they have fluid in reservoir as they will eventually ignore warning light or disconnect sensor (the two most common solutions in Nissan Altima forum).

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.

The information system head unit crashes (reboots) on demand when a MS Teams call is answered or initiated via CarPlay. Crashing of the head unit is 1) very distracting to the driver 2) avoiding it requires attention and ability to first determine incoming call is from MS Teams and then reaching down and unplugging the phone prior to answering it, causing a loss of Navigation and yet more attention loss 3) This loss of attention can cause lane deviation, lack of following traffic signals and other incidents. Problem is universal in Nissan head units in this series, google Nissan Head Unit Teams for tens of thousands of hits. Dealer and Nissan corp notified and ignore the problem. Nissan's partner in infotainment, Renault had the same exact issue and corrected it with an over the air update so it is easily fixed. Dealer inspected, MS and Apple as well, both say head unit firmware is at fault. Failure has occurred from day one, car is defective because of this significant cause of distraction. Please get this fixed before people die (if they have not already)
