Try to cut it back on and it wouldn’t crank up all the way, so I had to get the car to back to my address where I had a old mechanic come out to inspect with the problem. Engine light came on through some codes telling me it was ignition coils, and other things got those fixed same cold still appeared at the car inspected further, somehow some kind of way engine oil was in the connector to the ECM.

I bought my 2019 Nissan Altima SR from Westshore Mazda in Tampa. The next day I locked and unlocked the car and noticed that only the driver‘s door was working so three out of the four doors don’t lock and unlock by either the driver side door or the key fobs. I looked this up online and noticed it’s a defect on a lot of these models and the sentras.

I continuously have issues with it showing a crash and with the warning "engine malfunction, power reduced, service now" light coming on. This has been a recurring issue. There is always a light coming on in this car. I don't know if it is sensitive sensors or if it was poorly made.

I recently bought a 2019 Nissan Altima SR and when I got it home I noticed the door locks weren't locking or unlocking on 3 doors! The salesman didn't mention any problems with the car and I inspected it and didn't notice this until I got it home. This is a safety issue and everything should work on a vehicle when one buys it. There were no warnings and I have a family with two teen kids and one drives. I've reported this to the dealer and they haven't responded yet. I don't feel safe in the car with this problem and I also saw this is a common complaint on different websites. I can't afford to shell out more money for a repair that should of been done before they sold it to me. There should be an immediate recall that nissan needs to address this.

I’ve owned this vehicle since March 2023, and I have experienced several electrical issues. For instance, my car displays a malfunction warning and the check engine light multiple times throughout the month. When the engine malfunction warning appears, the engine will not accelerate, and if the vehicle is idling, it will shut off. I then have to restart the car. Another issue involves the door locks. I am sometimes unable to lock my doors using the key, or the lock will get stuck and not open. I have also seen other complaints reporting the same issue. This is concerning and poses a safety hazard.

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.

When putting my vehicle in reverse, I noticed the screen on the back up camera was blank/black color and did not show the angles/guide of which I was parking. I also noticed on my dashboard the clock at some point changed to "am" and said 109am when it was 529pm so I had to manually change the time. I never disconnected the battery for this to have happened. Everything else shows on the screen EXCEPT for the use of the back up camera so it must be a glitch with the software or wiring

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.

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.

On January 5, 2026, my son was driving to work at around 8:30 am EST. While waiting to turn left at a stoplight, his car inadvertently moved forward and collided with an oncoming vehicle. After the collision, he discovered the gas pedal had snapped off, causing the unintended movement. His vehicle was only traveling at 5 MPH or less at the time of impact, so the pedal breakage was not due to the collision. Stranded in the intersection, he was assisted by two individuals who pushed his car to safety. The police arrived, and a report was filed. Our insurance accepted liability for the accident, which was caused by the vehicle's malfunction, not my son's negligence.

My vehicle was taking to the dealership for an inspection for the nissan engine recall. During the inspection metal was found in my oil pan which the recall states they must repair or replace engine if any metal is found. I was told the engine would be replaced on 11/15/2025 but 2 days later 11/17/2025 I was contacted saying nissan denied my recall repair and to come back and pickup my vehicle. The recall states if any metal is found they must replace the engine but nissan refuse to fix the issue. The report they showed me Saturday stated oil was in my oil pan but now since they denied the recall the report was changed to nothing was found in oil pan. I notied the manager and after I mentioned that to the service manager they changed the report again stating metal was found.
