“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 in the oil pan to qualify for engine replacement. Approximately eight months later, on October 12, 2026, the same dealership inspected my vehicle at 197,467 miles. The technician's notes documented failed connecting rod bearings and an injector failure. The dealership recommended replacing the engine long block, turbocharger, and associated components. The vehicle remains at the dealership, unrepaired and available for further inspection by arrangement. I am concerned that the…”
“The contact owns a 2019 Infiniti QX50. The contact stated that while driving 70 MPH, the vehicle stalled; however, the contact was able to pull off the highway safely to a safe place. There was an abnormal burning odor coming from the vehicle. The oil pressure warning light was illuminated. The vehicle was towed to an independent mechanic and was diagnosed with a seized engine. The vehicle was later towed to dealer to see if the failure was associated with NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling). However, the contact was notified that failure was caused by sludge in engine and could not qualify under the recall. The contact stated that the vehicle had exhibited the failure described in the recall, but the manufacturer and dealer refused to repair the vehicle without charge. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 94,000.”
“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.”
