To Whom It May Concern, I am writing to formally request immediate assistance regarding a serious failure in my INFINITI vehicle. The vehicle's 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 should not exist in a vehicle of this class or price point. I am requesting the following: A full diagnostic review at no cost, Taverna Infinity is trying to charge me $300.00 for a simple diagnosis. …
Transmission & drivetrain
I am the owner of a 2019 Infiniti QX50, VIN [redacted] , and I am filing this complaint due to repeated, severe mechanical failures that have rendered my vehicle unreliable and unsafe. Since purchasing the vehicle, I have experienced catastrophic failures requiring two complete engine replacements, two turbocharger replacements, and one transmission replacement. My vehicle has spent over one year cumulatively at repair shops, leaving me without transportation and in constant fear for my safety. I am unable to drive this vehicle on the highway or for long distances due to the very real risk of sudden engine stall or failure at speed. I am aware that Nissan has issued Recall 25V-437 acknowledging manufacturing defects in the VC-Turbo engine bearings on the 2019-2022 Infiniti QX50, and I believe my vehicle's repeated failures are directly related to this defect. …
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.
