My wife was driving her fancy little car at night, and when she reached the halfway point (in the middle of an intersection), the ADAS apparently detected something that wasn't there and the car slammed on its brakes, putting her and other drivers at risk of a collision. She said there were all kinds of lights on the dash that lit up while the car was attempting to stop itself for no reason. I have had terrible experiences with our local dealer, and have not yet contacted them about this, but I plan to today. I plan to have them fix it (if they can), and then sell the car. Very nice car, but Infiniti clearly has a lot to learn about this kind of technology. My 13 year old Acura has the same…

My 2021 Infiniti QX50 has suffered a catastrophic internal engine failure. This vehicle is explicitly covered under active federal safety recall NHTSA Campaign 25V437000 (Infiniti Campaign R25A8/A9 / R25B1/B2) for defective, failing main and link bearings. The Infiniti dealership is actively refusing to honor the mandated federal recall remedy. The service department is attempting to illegally bypass the safety recall mandate by blaming the presence of engine sludge and claiming they do not visually see metal shavings. They are demanding that I pay out-of-pocket for a consumer-pay engine replacement. Under federal law, a manufacturer cannot deny a safety recall remedy based on vehicle…

The contact owns a 2021 Infiniti QX50. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from under the hood. No warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed and metal shavings were found in the oil pan. Upon further investigation, the contact associated the failure with NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling); however, the repair was denied due to the criteria not being met, a lack of maintenance records, and sludge in the oil pan. The vehicle was previously taken to a local independent mechanic to be diagnosed and there was no sludge in the oil pan from a previous…

There is an active and unremedied safety recall on my 2021 Infiniti QX50 (NHTSA Recall #25V-437) for a critical engine defect that can result in complete engine failure and risk of fire.

I first contacted Infiniti for assistance on March 19, 2026. As of today's date, after more than three months of communication with their representative (case #[XXX]),…

In June 2025, I received notification through the INFINITI app regarding a major engine recall involving engine bearing failure concerns affecting my vehicle. I brought the vehicle to Harte INFINITI for inspection regarding the recall and my electrical concerns. During that visit, dealership personnel acknowledged there were multiple vehicles experiencing similar engine bearing…
