This Problem Across All Years
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!

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.

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

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.

Without any warning or indicator light on the dash, the vehicle lost power when pulling out of our driveway - we live on a main road and were very lucky not to be hit by upcoming traffic. The car went into limp mode and would not accelerate past 20mph. We have been fighting with Infiniti for the last three weeks as no one can find the problem and they finally said a new engine was needed. There is on 35,000 miles on this car and we had to fight to have this replacement covered under warranty. Now that parts are back ordered and we are not receiving any help. We are three weeks without a vehicle and have no loaner vehicle. No one at Infiniti can give a timeframe for the resolution of this issue, what caused this issue and we are now very fearful that this will happen again - even with an engine replacement. This was very scary for our family and we are amazed that there was no indicator light or warning. The car didn't make any noises and was running great and then all of a sudden it would not go. Very alarming to say the least!

I purchased this 2021 QX50 Infiniti on [XXX] and have experienced consistent engine knocking. In checking out this problem, I have found that it is apparently a widespread problem with the engine in 2021 QX50 vehicles and can possibly lead to engine lock up and engine failure. The engine thus far has not locked up or failed. I have reported the issue to the dealership, Infiniti of Gwinnett located at 3090 Satellite Blvd, Duluth, GA 30096 and am scheduling to have the dealership investigate the problem. Needless to say this is a major concern and if there are ongoing NHTSA investigations and findings I definitely want to be made aware of same.
