On October 11, 2026, while driving my 2019 Infiniti QX50, I experienced a sudden loss of engine power. The check-engine light began flashing, the engine started shaking and making a knocking noise, and the vehicle would not accelerate beyond approximately 20 mph despite pressing the accelerator. This unexpected loss of power created a serious safety concern because I could no longer maintain normal driving speeds. In February 2026, at approximately 170,450 miles, my vehicle underwent an inspection at Infiniti of South Atlanta under NHTSA safety recall 25V437, involving defective engine bearings. The dealership informed me that the vehicle passed because insufficient metal debris was found…
Oct 11, 2026Unknown or other
While driving on the highway, all of a sudden I heard a very loud boom and then heard some wind/air movement. The sunroom shade was closed but when i pulled over and got out, the sunroof was shattered and the sunroom framing was coming off the car. The glass that fell into the car was caught by the sunroof shade but there were large chunks of glass on the outside too with some pointing outward (as if explosion from inside and pushed it out). If the shade was open, glass would have fallen into the car and potentially caused injury to me and my dog. There were no damage or cracks in the window that were visible to cameras above my garage that morning. The dashcam footage also does not show…

While driving my 2019 Infiniti QX50, the engine suddenly lost significant power and entered failsafe (limp) mode due to a diagnosed VCR actuator fault (diagnostic codes P11A8-00 and P11AC-00). The sudden power loss caused a single-vehicle accident. No injuries. The vehicle had recall 25V437 service performed at Infiniti of White Plains on 08/27/2026. The check engine light was documented as ON during that visit. I am requesting that NHTSA investigate whether the VCR actuator failure mode can cause sudden power loss creating a crash risk.

While driving on the highway the vehicle would not accelerate and the oil pressure light came on. After pulling over we noticed a slight burning smell and cut the engine. After a few minutes we tried to start the car again and it would not start. Vehicle was towed to independent repair shop who told us the engine had seized. We then learned of the current recall effecting this make model and year of vehicle. The vehicle experienced the same series of events outlined in a service bulletin for the recall. Vehicle was then towed to local Infiniti dealer and they were told the engine is seized and asked to drop oil pan per recall guidelines to confirm and diagnose. After not hearing from dealer…

#11753348 - on 7/1/2026, Infiniti Dealer found metal shavings actively present in my oil pan during a recall inspection. They passed the vehicle as good condition stating nothing found per a vehicle inspection report given to me. On July 25, 2026, my engine red light came on while driving and my engine began to shake violently and making a loud clunking noise. I towed the vehicle back to the dealer for another recall inspection. On 8/30/2026, the dealer informed me that the engine was failing due to the recall and needing bearing replacement but due to it passing back in July I would be responsible for replacing the bearings. They invoiced me for excess of $15,000, the diagnostic inspection…

To Whom It May Concern, I am writing to formally request immediate assistance regarding a serious failure in my INFINITI vehicle. The vehicleâs compressor stopped working with fewer than 60,000 miles driven, which is unacceptable for a new vehicle and raises significant concerns about manufacturing quality and safety. This failure is especially troubling because the vehicle has already been subject to multiple serious engine-related recalls number NHTSA Recall 25V-437. The air conditioning stopped working properly after the car was serviced for this recall. The combination of repeated critical issues and now a major component failure at under 60K miles suggests a pattern of defects that…
