2020 NISSAN ALTIMA Complaints

The contact owns a 2020 Nissan Altima. The contact stated while driving approximately 50 MPH, the vehicle lost motive power. The contact stated that the message "Engine Malfunction" was displayed, and the check engine, traction control, and Forward Collision Avoidance warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the mass air flow sensor needed to be replaced. The vehicle was repaired but the failure reoccurred days later. The vehicle was then taken to an independent machinic where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired but the failure persisted. The contact stated that the battery was replaced three additional times by several independent mechanics; however, the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

Since August of 2024 I noticed that my vehicle had strange noises coming from the engine and I was having a coolant loss but did not see anything on the ground. I then took my car to Nissan in New Orleans and they were recommending that I replace my entire engine. I’m not sure of their findings but still to this moment my vehicle still makes the same noise from the engine and still is having a coolant loss. I did notice that the coolant is overfilling in the reservoir tank and leaks out.

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.

This car is going to kill me! It randomly hits the brakes on the highways! I am literally driving a deadly weapon. I turn the emergency brakes off and had it checked and STILL brakes. It break everytime I pass a shade spot on the road and even highway going over 60 miles per hour! It hits the breaks while I am in traffic making the driver behind me almost hit my car. It breaks whenever I go under a tree. It breaks when I am in a parking garage when there are NO cars around. It breaks randomly in traffic with no cars too close by to create a collision. It breaks in front of a school bus that was driving close behind me. It hit the breaks going 30 miles per hour. If the school bus would have hit me then that would be child endangerment. The bus driver thought I would break checking him but it was hard to explain it was my emergency breaks. It’s been getting so bad that I am writing a complaint until something can be fixed or changed. It’s ruined my breaks in general from always setting off the emergency breaks. It is not even emergency breaking, it’s breaking to kill at given moment. It’s ruining my car and my ability to drive! This is not correct and it’s keeps going off even more. I am scared to even drive it. This has been happening since I got the car but for the past year since I turned off the sensor, it’s gotten SO much worse. It can turn deadly on my end or someone else’s. This was not properly designed for safety. It’s doing the exact opposite. This happens literally every week! So there is not way of giving you every single date nor do I have the time to wipe my phone out to take a video during those moments because it’s random.

Description of the Problem: For the past three years, my vehicle has experienced intermittent and sudden loss of power while driving, including on the highway. The issue is ongoing and has not been resolved despite having the throttle body replaced three separate times, totaling approximately $4,500 in repairs. Each replacement has resulted in the exact same malfunction: the car enters limp mode, drastically reducing power, which is especially dangerous when my children are in the vehicle. Component/Inspection: The issue appears to involve the throttle body and possibly the CVT transmission or related electrical system. The component has been replaced multiple times and is available for inspection if needed. Safety Risk: This malfunction puts my safety and the safety of my passengers at significant risk, particularly when driving at high speeds or in heavy traffic. The car's sudden loss of power makes it difficult to accelerate or maintain speed, which could easily lead to a collision/serious injury. Problem Reproduced/Confirmed: Yes. The problem has been witnessed and confirmed by Midas of Palm Bay, FL and Nissan of Melbourne, FL. Manufacturer Involvement: I reached out to Nissan, but they refused to assist with the repairs or offer any support. Warning Signs/Symptoms: Before the failure, the check engine light comes on, followed by a warning message that reads “Engine Malfunction.” Immediately after, the vehicle loses power and cannot accelerate normally.
