2020 NISSAN ALTIMA — Problems, Recalls & Safety Data

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.

Message popped up while driving saying “engine malfunction power reduced service now”. Pairs with the check engine light coming on

I received a Recall # R25B1 for my Nissan Altima 2020. I visited my local Nissan Dealer in Chelmsford, MA, on December 30, 2025. They explained that they saw an issue and that I would need a new engine. There are 32,000 miles on this vehicle. They began the process but were then told by Nissan Corporate that it did not meet the requirements of the recall, and they would not be replacing it. I am in the process of heading on a long driving trip and am very concerned with how this was handled. Nissan Customer Relations explained it wasn't covered under warranty, which has nothing to do with a recall. I am very frustrated and disappointed in Nissan. The mechanics at Nissan in Chelmsford took photos and sent them to Nissan, and they still denied it. With the car only having 32000 miles on it, it was probably if anything at the beginning of the failure. Please advise on going forward.

Door lock actuator will not function properly, causing my car to “lock” with my keys inside the vehicle. This is available for inspection upon request. This is a safety hazard because my drivers side, and both back doors do not lock properly and can be accidentally opened when driving. Mount Airy Nissan has been notified of this problem and have inspected my vehicle, and agrees there’s an issue. There were no warnings or notifications displayed prior to them going out. I bought the vehicle in October of 2024 unknowing the back drivers side door lock actuator was already broken. After going into a store, and accidentally locking my keys inside the vehicle, I realized there was a problem with the lock since I was able to open the back driver side door without needing to press the unlock button on my key fob. After this realization, my back passenger side and driver side door lock actuator broke.

Need a new engine / gasket confirmed by pep boys. Been at the dealership a lot more than usual lately and they kept telling me everything is fine with my vehicle
