ENGINE
I took my vehicle into Roswell Infiniti to repair/replace the engine bearings as instructed on the recall notice and as it has been making noises and I have experienced rough driving. The workers did not repair or replace the bearings. And when I reported rough driving and problems with the engine, they offered to charge me $175 for a diagnostic fee. The engine is still driving rough and making knocking noises.

ENGINE
Vehicle: 2021 Infiniti QX50 VIN: [XXX] Mileage at second failure: 154,282 miles I am reporting a repeat engine failure involving bearing material consistent with a known Infiniti VC-Turbo engine defect. The original engine in my 2021 Infiniti QX50 failed and was replaced with a brand-new long block in May 2024 at approximately 85,700 miles. I paid for this engine replacement out of pocket because the recall had not yet been issued. After the engine replacement, the vehicle was regularly maintained with full synthetic oil at reasonable intervals. There was no sludge present in oil, upon inspection. After receiving notice of Infiniti recall R25B2, I contacted the authorized Infiniti dealer (Ed Hicks Infiniti) to request an inspection and was advised to wait because the recall was temporarily on hold. As a precaution, I had another dealership inspect the oil and oil pan on August 18, 2025, and no debris or abnormalities were found at that time. On [XXX], the vehicle experienced engine failure symptoms and was towed to Ed Hicks Infiniti. The dealer inspected the engine and confirmed bearing material present in the oil pan with no sludge. This is the same failure mode described in the recall. Infiniti denied recall coverage and goodwill assistance solely due to total vehicle mileage, despite the fact that: • The failed engine was a replacement engine installed before the recall • The failure occurred well before a reasonable engine lifespan • The failure mode matches the recall defect • There was no evidence of neglect or sludge I am reporting this to document a repeat engine failure related to a known defect and to request regulatory review, as consumers who paid for engine replacements prior to the recall appear to be excluded despite experiencing the same safety-related failure.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
Around 530pm At the corner of Briarcliff Rd NE Atlanta Ga and N Druid Hills Rd NE Atlanta GA As I was about to accelerate after the Red Light turned green, my car experienced a significant loss of power. Several warning lights came on, the engine light came on and a warning that said System Default came on. I was almost rear ended but was able to put on my hazards and coast to the side of the road, where I turned the car off and back on. It continued to display the warning and system default message as well as loss of power. I was able to coast into the parking garage at work and park. I am a healthcare worker and my shift ends at midnight. I have a 30 minute drive home and I’m afraid my car may do the same thing-lose power- and that can be catastrophic on the interstate. This is not the first time this has happened. I took my car to Infiniti and they said the recall was cancelled for now. I have two small children that I have to transport in my car and it is unsafe. We need a solution asap!

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS
I received the recall notice approximately 2 weeks ago, the notice state “parts are anticipated to be available beginning in Q4 2025” so I did not schedule for an inspection. This morning, 09/16/2025, I was unable to accelerate after being stopped at a traffic light. I was able to get to a parking lot to have my car towed to an Infiniti Dealership/service center for $260 at their recommended tow provider. After calling the service department to inform them of my vehicle arrival, I requested they run diagnostics for the recall I had received regarding my engine. I received a call shortly after they received my vehicle informing me the diagnostics test would be $250. I agreed and after several calls with no answers I get informed my engine has failed, it is not due to the recall and my cost will be $12,100 for replacement of my engine. I was later informed they had not investigated the recall at all and I would need to sign forms for this. I feel Infiniti of Orlando is not willing to honor the recall repair and looking to take my money for the $12,100 engine replacement.

ENGINE, ELECTRICAL SYSTEM
Vehicle Issue Summary – 2021 INFINITI QX50 I purchased a 2021 INFINITI QX50 in March 2024. Recently, I received notice of an active safety recall (NHTSA 25V437) related to the VC-Turbo engine bearings. In addition to the recall alert, I’ve also experienced several concerning symptoms: 1) A knocking noise when reversing. 2) The malfunction indicator light turning on and off intermittently. 3) Other irregular behaviors that raise concerns about engine performance and overall safety. Given the recall and these symptoms, I’d like to schedule an immediate inspection and any necessary repairs. My job requires me to drive multiple children on a daily basis and is a safety concern for the family I work for. This effects my work situation tremendously and my ability to perform my job responsibilities.

The specific component or system which has failed and or is malfunctioning is unknown due to the fact the manufacturer and dealer were unable to properly diagnose and resolve the issue. The vehicle continues to malfunction, as of 8/28/2025. Beginning [XXX], the vehicle's engine began to make a very loud, concerning noise. The vehicle was inspected by the Infiniti of Mobile Dealership, in Mobile, Alabama on 12/18/2023. The dealership's service technician diagnosis at the time was the vehicle's radiator fan was stuck wide opened due to a failed idpm and a radiator leak from a crack. The dealership installed a motor and fan assembly and a control unit ipdm. However, the noise persisted after the "repair" and in addition, the heater/ac was not working properly. The vehicle was brought back to the same dealership on 02/22/2024 for further diagnosis. No action was taken by the dealership to repair the issue. The noise and malfunctioning of the A/C/heater persisted and became worse over time and the vehicle was then taken to the Infiniti of Memphis dealership in Memphis TN om 7/2024. The noise was much louder and the A/C stopped working in 98 degree weather as the car overheated. The vehicle's A/C continued to suddenly go out while the vehicle was in motion in high temperatures between 95 to 100 degrees Fahrenheit, causing a health and safety concern. The dealership reviewed the history of the problem and could not properly diagnose the issue. The dealership claimed the vehicle was working exactly as it should be. The vehicle owner insisted it was not working properly and the Infiniti of Memphis Service Manager contacted the Infiniti of Mobile Service Manager and both agreed to replace the fan assembly once again. The replacement failed to repair the problem. Both dealerships stated there was nothing further it could do. The Infiniti USA manufacturer Consumer Affairs Department was contacted by the owner of the vehicle on 8/13/2024 to lodge a complaint. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

The system falsely beeps and displays collision alerts even when no vehicles or objects are present. The system has also initiated braking on the highway with no obstacle present, which is a major safety concern for me and for other drivers. Conversely, when an actual vehicle approached too closely, the system failed to alert or respond at all.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ENGINE, ELECTRICAL SYSTEM
While driving on the highway and having no visible vehicle in front of me; my car automatically slams on the breaks and the Emergency Braking system light comes up on the dashboard briefly and then disappears. This has occurred multiple times while driving on highway speeds. It is concerning because there has been no evident or visible vehicles in front of my vehicle when my car abruptly slams on the brakes. To me this is a safety concern. I had mentioned this concern to the service advisor at Infiniti, but he said it would cost approximately $200 just to diagnose it. My vehicle is currently at a Infiniti dealership. They found a lot of metal debris inside the oil pan.
