2019 Infiniti QX50 Complaints

The vehicle experienced hesitation, delayed acceleration, and multiple warning lights while driving. The loss of power was severe enough that the driver became afraid to make left turns across traffic because the vehicle would not accelerate quickly or consistently when needed. This created a significant safety risk, as the driver could not reliably judge whether the vehicle would clear an intersection before oncoming traffic. A diagnostic trouble code related to the turbocharger control system was retrieved during the first visit to the dealership. The vehicle was brought in for a recall inspection involving potential engine bearing wear and oil pressure issues, but the recall inspection was not performed on the first visit and was rescheduled. On the way to the recall appointment, additional warning lights illuminated and the vehicle again lost power. The dealership kept the vehicle and stated that further diagnostics were needed. Over several days, the dealership reported that dia...

I am the owner of a 2019 Infiniti QX50, VIN [XXX] , 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. Despite multiple repair attempts by authorized Infiniti dealerships, the underlying issues have not been resolved. I am requesting th...

The contact owns a 2019 Infiniti QX50. The contact stated that while driving at an undisclosed speed, there was an abnormally loud sound coming from the vehicle. There was no warning light illuminated. The contact received notification of NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling). The vehicle was taken to the dealer, where it was diagnosed with engine failure due to metal shavings found in the oil pan. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was denied an engine replacement. The dealer informed the contact that the claim was denied due to the vehicle exceeding the warranty mileage and a lack of proper maintenance. The contact provided maintenance records; however, the claim was still denied. The dealer stated that the failure was related to insufficient maintenance and not the recall. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 135,000.

Good morning, I am writing to formally escalate a serious and unresolved safety concern involving my vehicle and to follow up on my existing case (Case #XXX). On April 22, 2026, while driving on the highway at approximately 55 mph, my vehicle suddenly performed a hard stop as if it detected an imminent collision. At the time, there were no visible obstructions or vehicles directly in front of me that would have warranted automatic emergency braking. This is a repeat issue. A nearly identical incident occurred on August 8, 2025, which was previously reported. Despite that report, the problem remains unresolved and continues to present a significant safety risk. These unexpected braking events create a hazardous driving condition with a clear risk of rear-end collision, particularly at highway speeds. Based on the pattern and circumstances, this strongly suggests a false activation of the automatic emergency braking system or a related safety system malfunction. Given the repeated n...

Recall on my 2019 infiniti qx50. I am a 100% service connected from the vietnam war I can no longer drive and because this is a critical safety recall I sent a email to infiniti asking for help in getting the vehicle towed repaired and returned to my home address it is 100+ miles one way. Again, I am a 100% service connected war veteran. The car was being used to carry me to appointments most of which is the VA. medical center. I am on disability income and i can not afford to have it towed so the vehicle is garaged at my home because I don't want anyone driving get hurt.
