2019 Infiniti Qx50

2019 Infiniti QX50 with engine bearing failure defect matching NHTSA Recall #25V-437. Vehicle was sold to me on 12/24/2025 by a dealer, MORE THAN FIVE MONTHS after the recall was issued on 07/14/2025. The dealer NEVER disclosed the active, unrepaired safety recall. Two months after purchase, the engine developed loss of power and unusual noises - exact symptoms described in the recall. An independent mechanic diagnosed a pre-existing camshaft bearing defect. Despite component replacement, symptoms persist, confirming the defect was present at time of sale. This is a serious safety violation. The dealer knew or should have known about the recall via CARFAX and failed to disclose it, violating federal law 49 U.S.C. § 30120. The vehicle is unsafe to drive with an unrepaired engine bearing failure. Safety Risk: Engine bearing degradation can lead to complete engine failure while driving, resulting in loss of motive power and crash risk. Requested Action: Federal investigation into dealer's failure to disclose active safety recalls.

The issue on the 2019 Infiniti QX50 it's not the motor that they had the recall on it's the VCR actuator it goes bad causes the bracket that's connected to rub against the side of the engine block causes it to have metal shavings and the car to go in limp mode and can cause an accident it's a common issue just put one in and already bad not even a year The original one made it to $47,000 mi before going bad

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 diagnostics were being performed, but no diagnostic results, measurements, technician notes, or recall determination were provided. The manufacturer later confirmed that they had not received any diagnostic information from the dealership and could not proceed with the recall case. The dealership verbally stated that the turbocharger issue was “not related to the recall,” but no documentation was provided to support this. Instead, the dealership sent a cost‑sharing repair proposal without identifying the failed component, the cause of the failure, or whether the failure was related to the recall. Warning lamps and reduced performance first appeared on the initial date of symptoms and continued through the recall appointment. The recall process remains incomplete because the dealership has not provided the required diagnostic documentation.

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 that NHTSA investigate this vehicle and pressure Nissan/Infiniti to provide an appropriate remedy, including a full vehicle repurchase or buyback. My family's safety is at risk every time we are forced to drive this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 nature of this issue and the potential safety implications, I am formally requesting: * Immediate escalation of this case to the appropriate engineering or safety review team * A full investigation as a potential safety defect * Identification of any related technical service bulletins, recalls, or known system issues * A clear plan and timeline for diagnosis and resolution at an authorized INFINITI dealership * Confirmation of whether reimbursement or other corrective action will be considered given the ongoing safety risk and repeated service attempts Please confirm receipt of this escalation in writing, along with next steps and assigned case handling details. I expect timely and serious attention to this matter given the safety risk involved. Sincerely, XXX XXX

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.

Sun roof exploded while driving at highway speed.All glass came into vehicle and caused a critical issue requiring me to pullover in an unsafe manner in order to not get cut by glass.

The car had a power failure so I took it to the dealer to have it checked since it had an open recall, according to what the mechanic tells me is that the fault comes from the mild tree, but he does not tell me what causes that failure and he has not given me the results of the recall either

I am filing a safety complaint regarding my 2019 Infiniti QX50 experiencing engine failure consistent with known bearing defects. On February 13, 2026, while driving from [XXX] to [XXX] on the highway, my vehicle began shaking severely, producing a rattling/knocking noise from the engine, and losing power while in motion. This created a dangerous driving condition and required the vehicle to be towed. The vehicle was taken to a repair shop in [XXX] , where it was diagnosed with engine bearing failure. The shop indicated that this issue was consistent with a known defect and that there was an active recall related to engine bearings at that time. Based on that information, the vehicle was towed to Bob Moore Infiniti in [XXX] for recall inspection and repair. Initially, the dealership indicated that there was an issue and that it was associated with a recall. However, they later reversed their position and stated that the vehicle was “fine” and did not perform any recall repair, despite the ongoing symptoms and prior diagnosis. The vehicle continues to exhibit the same dangerous symptoms, including shaking, engine knocking, and loss of power, and remains diagnosed by another repair facility as having engine bearing failure. This is a serious safety concern because the vehicle can lose power unexpectedly while driving at highway speeds. Additionally, there appears to be inconsistency in how this known defect is being handled, as my vehicle was initially identified as affected but later denied repair. I am requesting further investigation into engine bearing failures in the Infiniti QX50, as well as inconsistent recall application for this defect.

On March 26, 2026 my 2019 Infiniti QX50 (VIN: [XXX] ) experienced complete loss of motive power while exiting the freeway. My blind mother and [XXX] autistic son were both passengers creating a serious safety emergency for two disabled individuals. On March 28, 2026 Les Schwab Tires (Store [XXX] ) professionally documented metal shavings in the oil pan on official invoice stating ‘SHAVING IN OIL PAN’ with my VIN recorded. I brought the vehicle to Infiniti Roseville [XXX] ). Their own official inspection report R/O 101930 dated March 28, 2026 confirms: ‘REMOVED OIL PAN AND INSPECTED FOR BEARING DEBRIS. FOUND SMALL AMOUNT OF METAL SILVER COLORED.’ The report also documents my reported intermittent power loss and references two photos of the debris taken during inspection. Despite finding documented metal debris consistent with recall R25B2 bearing failure, Infiniti Roseville is denying engine replacement claiming silver colored debris does not qualify. Nissan’s published recall criteria makes no such color distinction — it states metal debris qualifies for engine repair or replacement at no charge. Warning symptoms began December 5, 2025 including headlight flickering, high pitched engine whistling, VDC warning light January 25, 2026 — all documented with timestamped photos and video. The vehicle is currently at Infiniti Roseville. I am requesting federal intervention as the dealer is not complying with recall R25B2 repair criteria and is applying internal standards that contradict Nissan’s published recall documentation INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle was inspected at an authorized Infiniti dealership under an active recall. During that inspection, metal debris and loose bolts were found in the oil pan, indicating internal engine damage consistent with the recall condition. Despite this, Infiniti declined to repair or replace the engine. the engine failed completely while I was driving at highway speed, causing sudden loss of power and creating a serious safety hazard. I was left stranded in active traffic conditions, placing myself and others at risk. This incident raises significant safety concerns, including: Failure of the manufacturer to properly remedy a known recall condition, Continued operation of a vehicle with a known defect, Risk of sudden engine failure during normal driving conditions. Additionally, I did not receive timely notification of the recall. I should have been notified months earlier but only received notice on February 10, 2026. I have documentation from the dealership confirming the presence of metal debris and bolts in the engine, as well as photographic evidence of the damage. I am concerned that other vehicles with this defect may not be properly repaired, potentially leading to similar dangerous failures. Infiniti’s refusal to address a clearly defective engine identified during a recall inspection represents a serious safety issue that warrants investigation. I respectfully request that NHTSA review this matter and determine whether Infiniti is complying with its obligations to properly remedy recall-related defects.

Vehicle: 2019 Infiniti QX50 Mileage at engine replacement: 31,830 miles Date of engine replacement: August 2023 (recall-related repair) The engine in my 2019 Infiniti QX50 was replaced under recall at 31,830 miles in August 2023. Approximately 18,633 miles later, the vehicle began experiencing transmission malfunction symptoms consistent with CVT failure. An independent mechanic diagnosed the CVT transmission as needing replacement. I then took the vehicle to an Infiniti dealership, and they confirmed transmission issues but declined warranty coverage because the powertrain warranty expired February 28, 2025. The transmission is directly integrated with the engine in this vehicle. Following the engine replacement, the transmission began exhibiting unsafe operating behavior, including hesitation, loss of acceleration response, and drivability instability. There are widespread consumer complaints and litigation involving this engine and CVT transmission combination in the 2019 Infiniti QX50. Infiniti extended coverage for the engine but has not extended coverage for the transmission despite known reliability concerns. I am now afraid to operate the vehicle due to concern of sudden transmission failure while driving, which could result in loss of power in traffic and create a safety hazard. I am requesting that NHTSA investigate this recurring pattern of CVT transmission failure following engine defects in the 2019 Infiniti QX50.

2019 Infiniti QX50 was purchased new 9/3/2018 Engine safety problems started 9/3/22 and it was fixed in a two days. Total engine failure diagnosed by Infiniti Cerritos on March 31, 2025. The car was at 103,900 miles at this time. At this time the warranty coverage was for 72,000 miles and not extended to 120,000 miles yet. I paid for the replacement of the engine on 9/5/2025. I later got a recall notice and it said that the warranty engine coverage had been extended to 120,000 miles and that I would get reimbursed for repairs. I never got reimbursed after I submitted a reimbursement claim form through Infiniti assist. I keep getting the run around at Infiniti Consumer Affairs. I submitted a Lemon Law claim and the arbitrator is showing a lot of bias and I keep getting the run around as well. No arbitration meeting has been scheduled. I now got a 2nd recall notice on January 29,2026 stating that the engine oil pan needs to be checked for metal debris and it’s possible that engine will need to be replaced if metal found. I scheduled an appointment on February 10th, 2026. At this appointment I also notified them that I still hear a noise in the engine. Infiniti Cerritos refused to do the recall. They also want to charge for inspection diagnosis of the engine noise when it should be covered under the warranty and recall notice. It says free of charge on recall notice. This car is obviously a lemon because if the engine gets replaced it’s bound and will continue to have the same type of safety issues.

I have called sewell infiniti multiple times for service appointment to check on my engine , per the recall notice. They said they were not taking appointments because no parts yet. And just wait for them to contact me. I have call them around October and December. Both times they said the same thing.
