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
I experienced loss of power while on the interstate and at that time I was unaware of what the issue was until I received a Recall regarding the engine. I often have my grandson [XXX]) who sits in the back seat of my 2020 QX/50. I went into the Infiniti of South of Atlanta, Union City, Georgia 30291 and I was informed by my Service Representative (Mrs. Dyamond Cobb) on September 12, 2025 @ 11:00 a.m. that this Recall has been suspended. I was given info to reach out to Infiniti Consumer Affairs Department and also to submit through on line a complaint to www.safercar.gov and I am submitting this info on line as a means to document that I am having serious concerns. I am making payments on a vehicle that could cost me and my family our life! In addition, the dealership is definitely NOT ACTING ON BEHALF OF THE CUSTOMER WHATSOEVER! I will SUE should this vehicle loose power in the stream of ongoing traffic or on the interstate, this is my only vehicle and no one is willing to assist with repairs KNOWING THERE IS AN ENGINE ISSUE and a bearing failure may cause a break in the engine block allowing hot oil to be discharged increasing the risk of an ENGINE FIRE! This is a SERIOUS SITUATION and I SHOULD NOT BE FORCED TO DRIVE AN UNSAFE VEHICLE THAT I CURRENTLY MAKE PAYMENTS ON!!!!

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
The vehicle's engine light turned on. The engine light remains on, and frequently the Malfunction and System fault See Owners Manual will display. When the malfunction message appears all the traction lights are also turned on. The RPM's in the vehicle are very accelerated, and it's difficult to drive the vehicle. The vehicle will also produce a very heavy smog smell. I took the vehicle into the retailer several times and nothing was done. The manufacturer is also not taking responsibility and stated the issue is unrelated to the engine bearing recall.

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.

ENGINE
I own a 2020 Infiniti QX50 that is included in NHTSA Recall 25V-437 for defective engine bearings that may cause sudden engine failure. My VIN has been confirmed by the dealer as part of the active recall. I have already noticed intermittent shaking at idle and a grinding sensation during acceleration, which are early warning signs listed for this defect. I am worried these symptoms indicate my engine may be starting to fail. My Infiniti dealer told me they “see the recall as active,” but that it is on hold and they cannot inspect or repair my vehicle at this time. They also stated they cannot provide me with a loaner or rental vehicle in the meantime. I believe this puts me, my family, and others on the road at risk because engine failure could occur suddenly while driving, leading to a crash. I am nervous to continue driving the vehicle, but I have no safe alternative since Infiniti has refused to provide a replacement vehicle until repairs are available. I am requesting NHTSA to investigate this delay and Infiniti’s refusal to provide a safe alternative vehicle while recall repairs are unavailable.

ENGINE
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

ENGINE
I was driving at the intersection of South I-55 and I-355 on the left most lane at 70 mph. All of a sudden, my car started knocking and since there was no shoulder to the left I had to move to the right by managing to get through multiple lanes to get to shoulder safely. Given the issue with engine, it would not accelerate so I had to safely decelerate and come to a stop. I called the towing company and they towed my car to the dealership. This car had a recall when the dealer contacted me and I had them take a look at 98K miles and they stated everything was fine. Following few weeks later, the engine completely gave out. The dealer is working with manufacturer to get the engine replaced. However, he is not sure who will pick up cost for replacing turbo. Turbo is part of the engine and should also be replaced under the recall. Needless to say, this was a dangerous situation and I am glad the situation had a safe outcome.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
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.
