What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“Didn't know what the list this one but at a certain speed on the highway the hood latch comes loose unlocks, and my backup camera All of a sudden doesn't always work, sometimes the screen is completely black... Also the sensor that tells you that a car is too close to you keeps turning itself off and then when you check the radar sensor to make sure that it's clear of debris there's no debris but yet this thing just keeps turning itself off while you're on the highway or local road... I will list when the first problem started happening and then we know when the other ones start happening consecutively afterwards.. electrical issue front passenger door will not open automatically Putting my passenger at risk”
“My Nissan Altima's power door locks failed making entry and egress sometimes impossible. While the key will unlock the driver's door, rear seat passengers have been unable to exit the vehicle without assistance due to the door being locked. Premature power door lock actuators in Nissan vehicles is reportedly a very common problem according to my research.”
“The driver's side door lock actuator stopped working around June 2024. Haven't replaced it yet, but bought another part. Read where others are having same issue. Just in the last couple of weeks, around June 15th, 2025, my rear driver's side door actuator stopped working as well. I have to crfrawl in from the other side and unlock the doors. Safety issue since the doors do not lock or unlock.”
“My back doors do not lock with the FOB or the interior door lock/unlock button. I have to manually unlock and lock my rear doors. This is a defect that Nissan is well aware of and seems to not care. My car only has 63,000 miles on it.”
“As I was driving on a highway, my sunglasses and light compartment on my roof completely fell out of my roof in front of my windshield view. I contacted Nissan and they stated that they could do absolutely nothing for me. Did not have any concerns regarding the fact that it almost caused me to get into an accident as it came swinging right in front of me and almost hit me and my head. This is also a very common issue when you look it up online with these vehicles.”
“Vehicle turned off while driving. Battery disconnected as the battery terminal connector got lose. after a quick clean-up of the terminal corrosion, it was obvious that the terminal has completely deteriorated (corroded) and has no more strength to hold a good contact to the battery terminal.”
