Altima

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.

On August 30, 2025, while driving on the highway, my 2019 Nissan Altima displayed a “CVT (AT) Hot / Power Reduced” warning. Power was limited, but the engine did not shut off. I immediately scheduled service at Paul Miller Nissan in Fairfield, CT. At the September 2, 2025 visit, the repair order stated: “Customer states CVT (AT) Hot Power Reduced display in dash. All past codes stored; cleared all past codes stored.” No complete diagnostic test, CVT pressure test, or fluid inspection was performed. The dealership did not preserve the freeze-frame data from the TCM. I was told that no current fault codes were present and that the vehicle was safe to operate. Relying on the dealership’s professional assurance, I continued normal use of the vehicle. About a couple of weeks later, the vehicle began to jerk and lose smooth acceleration intermittently, worsening by the sixth week. I promptly returned for service. On October 21–22, 2025, the same dealership confirmed transmission codes P0776 and P17F0, diagnosing a CVT failure and recommending full replacement. When questioned about prior diagnostic data, the service manager stated that all data from the September visit had been cleared and that the freeze-frame information was deleted and no longer available. This handling contradicts Nissan’s standard CVT diagnostic protocol, which requires documenting stored codes, inspecting CVT fluid condition, and recording internal temperatures before clearing data. Nissan Consumer Affairs later stated their review relied solely on the dealership’s findings and that missing diagnostic data would not be retrieved. Since the confirmed failure, I have been forced to rent a vehicle at my own expense, exceeding $1000 to date. The vehicle’s reduced power and transmission failure created a serious safety risk, especially as I transport my children in this vehicle. The dealership’s erasure of diagnostic evidence prevented accurate evaluation and timely repair. The issue remains unresolved.

The airbag system failed to deploy during a collision. The vehicle is currently in not my possession. The airbag control module, sensors, and airbags themselves can be inspected to determine the cause of non-deployment. 2. How was your safety or the safety of others put at risk? My safety was put at significant risk because the airbags did not deploy during the impact. This increased the potential for serious injury to the driver and passengers during the crash, as the airbags are a critical part of the vehicle’s safety system designed to prevent head and chest injuries. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The vehicle has not been inspected by my insurance and considered totaled. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? A police report was filed for the accident, and my insurance company has been notified. The vehicle has been inspected by insurance, but both parties have been informed of the issue and an inspection has been taken place 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights or airbag system messages appeared prior to the crash. The airbag light on the dashboard was functioning normally before the accident, and there were no indications of a malfunction with the safety restraint system.

NHTSA Online Complaint Vehicle: 2019 Nissan Altima VIN: [XXX] Recall: R25B1 (NHTSA Recall No. 25V-437) Description of the Problem: My vehicle is affected by recall R25B1 (NHTSA Recall No. 25V-437) related to potential bearing failures in the 2.0L VC-Turbo engine. Nissan announced this recall on June 26, 2025, but the status remains “Incomplete – remedy not yet available.” I have contacted Nissan Consumer Affairs and local dealerships several times, but they confirmed that there is no repair or parts available. Due to this unresolved safety recall, my state’s DMV has refused to register my vehicle, meaning I cannot legally operate it. This delay has caused significant hardship and prevents me from using my vehicle, even though the recall involves a critical safety risk (potential engine failure while driving). I am requesting that NHTSA investigate this issue and require Nissan to expedite a remedy for recall R25B1. I need a car urgently to drive to work.
