This complaint concerns a 2019 Infiniti QX50 with a 2.0L VC-Turbo engine affected by NHTSA Safety Recall 25V437, involving potential engine bearing failure, loss of power, and fire risk. Before purchasing the vehicle at auction, we performed due diligence by obtaining an AutoCheck history report, which revealed no issues suggesting warranty or recall coverage had been compromised. Before our purchase, Infiniti performed a recall inspection, documented engine sludge but no metallic debris, reassembled the oil pan, and marked the recall completed. The sludge findings were never disclosed to us before purchase. After purchasing the vehicle, we discovered metallic debris in the engine, raising concerns about bearing damage associated with the recall. Infiniti initially claimed there was no open recall because the previous inspection was completed. After further discussions, Infiniti acknowledged the recall issue but refused repairs, citing the previously documented sludge. We brought the vehicle to an authorized Nissan dealership for inspection. Despite the metallic debris findings, Infiniti refused repairs, claiming sludge voided the manufacturer's warranty. A subsequent goodwill review was also denied. We dispute Infiniti's use of a warranty exclusion to deny a federal safety recall remedy. A voided warranty does not automatically eliminate a manufacturer's recall obligations. Furthermore, the previous sludge finding does not establish that the engine is free from the identified manufacturing defect. Potential engine bearing failure creates serious risks, including sudden loss of power, crashes, and engine fires. We request that NHTSA investigate whether Infiniti properly completed the original recall inspection and whether its refusal to provide recall repairs based on engine sludge complies with federal safety recall requirements.

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 engine experienced a bearing failure after previously passing an inspection under a safety recall involving defective engine bearings. The relationship between this failure and the recall has not yet been determined. I request that NHTSA review this incident and investigate whether the failure may be related to recall 25V437 or the effectiveness of the completed recall remedy.

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 anything coming towards the car at that moment. It is clear on the images the glass is angled out from the car. I have seen this exact case on the news and online for both Infiniti and Nissan. I was a couple miles from Infiniti and brought it in. The team working (sales team only onsite that day) have not seen this and recommended I submit to insurance as they cannot confirm the cause. I will be submitting to Infiniti Consumer Relations once they are open. I submitted claim to insurance, pending response. (Images named "IMG..." were photos taken off the exit immediately after the incident occurred.)

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 after 2 weeks I follow up to be told the vehicle had not been looked at yet and they would get it in that day and call me no later than next day. Once week goes by and they still had not contacted me. I contact them and am told the only thing wrong with my vehicle was a dead battery and that would cost X amount to replace. At that point my car had been sitting in the summer sun for 3 weeks, of course the battery is dead. I reluctantly agree to the repair. After another week I follow up on the repair and am told after replacing the battery the car still will not start and I asked again about the recall diagnosis. After another week, we contact them and am told the car shows information consistent with bearings recall and they submit to Infiniti to approve. A repair timeline is discussed at this time. 24 hours later we are contacted by dealer for first time and told it now does not fit under recall. Have a case with Nissan consumer affairs. We have asked several times for work order and photos of what they are looking at and have not received. Dealer is now asking for $300 plus dollar diagnostic fee to see what is wrong. They say sludge caused engine failure and not recall issue. It has been 46 days at this point and no resolution. Per recall, sludge can be caused by bearings issue

#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 of 270 and demanded that I return the loaner vehicle. When I returned the loaner vehicle on 9/3/2026, they attempted to sell me a new/pre-owned vehicle instead of providing me a written denial refusal notice of not honoring the vehicle recall. On 9/5/2026 Infiniti Consumer Affairs representative verbally confirmed that they were informed by the dealer that there were metal shavings present in my oil pan but denied the repair because there were not "chunks" or "clusters" of metal present. The manufacturer verbally claimed that the metal debris did not meet an internal, undocumented threshold of "chunks" or "clusters," and explicitly stated that Infiniti considered my vehicle's mileage and vehicle age and sludge present on the latter inspection that was not present on July 1 nor reported in making this denial decision. The representative also referenced a photograph sent to them at the end of August as justification for the denial. This photograph was not taken nor sent to them during the actual July 1st inspection. The dealer had already informed me that they did not send the manufacturer a photograph on July 1. The manufacturer refused to provide me written notice refusing to honor the recall and said to get it from the dealer.

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. Written confirmation of whether this failure is related to existing or pending recalls A clear explanation of how INFINITI intends to ensure the long‑term reliability and safety of this vehicle Consideration for replacement or buyback if the vehicle continues to demonstrate systemic defects I expect a prompt response, as this situation has already caused significant inconvenience and raises legitimate concerns about the vehicle’s safety and reliability. Thank you for your attention to this matter. I look forward to your timely reply. Sincerely,

My 2019 Infiniti QX50 has the KR20DDET 2.0L VC-Turbo engine involved in NHTSA Recall 25V437/Infiniti Campaign R25B2 for potential engine-bearing failure, but my VIN does not currently show an open recall. The vehicle is at Infiniti Milwaukee, [XXX], [XXX]. During inspection, bronze-colored metallic glitter/debris was found in the engine oil. This may indicate internal bearing wear and appears consistent with the metal debris that Recall 25V437 requires dealers to check for in the lower oil pan. The dealership is refusing to acknowledge or report the bronze-colored debris as possible bearing material. It reported only “engine sludge” to Infiniti and is treating the engine repair as customer-pay. Sludge and bronze-colored metallic particles are visibly different conditions. The vehicle and engine are available for inspection at the dealership. I requested preservation of the oil, filter, oil-pan contents, photographs, video and technician findings. Bearing failure could cause engine damage or loss of power while driving, increasing crash risk. Warning lights before inspection: UNKNOWN. The exact composition of the debris is UNKNOWN pending testing. You see metal debris in oil pan of the video of an engine that failed citing sledge while clearing seeing metal debris in the photo provided by the dealership. I request that NHTSA investigate whether this vehicle was incorrectly excluded from the recall and whether recall-related metallic debris is being misclassified as sludge.

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 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.

ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE 2026-04-23 · NHTSA 11733234

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 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.

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.

A few months ago, I received an email from CarFax letting me know that my vehicle, a 2019 Infiniti QX50 with 2.0L Turbo Engine had a major recall (NHTSA Recall Campaign No. 25V-437). The letter indicated the recall was due to issues with the engine bearings which could lead to a catastrophic failure. I wasn't sure what this meant, so I took the car to Austin INFINITI. The technicians checked the oil pan to see if there were issues. My understanding is that the oil pan should have been removed, drained of all oil to ensure there were no issues that could lead to the catastrophic failure of the engine. None of this was done. I was given my car back and told all was okay. Unfortunately On the evening of November 10, 2025, my vehicle’s engine suddenly seized while driving at highway speeds. Fortunately, I was able to coast onto the Frontage Road. For my protection, the Police Department arrived quickly to park police vehicles in the front and back of my car with their lights on to avoid a nighttime collision or worse. I had no idea why my engine suddenly lost power while driving down the highway and continued to refuse to start despite repeated attempts to restart the vehicle, the engine would not start. I was scared to death and this situation has exacerbated my current diagnosis of PTSD for which I am currently in treatment. This was a horrifying event that could have cost me my life. I can't eat or sleep and experience nightmares that my car died, then I am hit by a car driving at highway speeds as I tried to exit the vehicle. My wife and I are both terrified of driving the car now. I tried to resolve the issue with my local INFINITI dealership and even contacted NISSA/INFINITI executives. I was met with disregard, disrespect and a $1,700 bill to replace the starter that burned out as we kept trying to start the car. The starter burnout was a secondary cause due to the primary issue of the engine seizure. Infiniti disagreed and insisted on the $1,700 for the starter.
