I am writing to request NHTSA’s assistance and guidance regarding an unresolved safety recall affecting my 2022 Infiniti QX50, VIN [XXX]. I imported this vehicle from the United States to Abu Dhabi, United Arab Emirates, in 2023. The vehicle remains in Abu Dhabi and is awaiting shipment back to the United States. I was evacuated from the UAE, and my employer has not permitted me to return. As a result, I am unable to take the vehicle to a U.S. Infiniti or Nissan dealership to have the recall inspected and remedied. Before arranging shipment, the shipping company informed me that it will not proceed while the recall remains open unless I provide additional documentation showing that the recall has been resolved. I contacted Infiniti and Nissan dealerships in the UAE and the wider Middle East to ask whether they could inspect the vehicle and complete the applicable recall remedy. I was advised that these dealerships do not inspect or perform recall repairs on U.S.-specification vehicles that have been imported into the region. This has left me in a difficult position: the vehicle cannot be shipped unless I provide documentation that the recall has been addressed, yet the local dealerships I contacted have indicated that they will not provide the inspection or remedy because the vehicle is a U.S.-specification import. I respectfully request NHTSA’s assistance in identifying an appropriate path forward. Specifically, I would appreciate guidance on whether the manufacturer can provide an authorized remedy, written confirmation of the recall status and available remedy, or other official documentation that may help the shipping company determine whether shipment can proceed. If NHTSA cannot issue a statement confirming that the recall cannot be remedied in the UAE or Middle East, I would appreciate referral to the appropriate manufacturer contact or agency resource that can address this situation.

POWER TRAIN, ENGINE
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.

UNKNOWN OR OTHER
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 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.

ENGINE, POWER TRAIN
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

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
My wife was driving her fancy little car at night, and when she reached the halfway point (in the middle of an intersection), the ADAS apparently detected something that wasn't there and the car slammed on its brakes, putting her and other drivers at risk of a collision. She said there were all kinds of lights on the dash that lit up while the car was attempting to stop itself for no reason. I have had terrible experiences with our local dealer, and have not yet contacted them about this, but I plan to today. I plan to have them fix it (if they can), and then sell the car. Very nice car, but Infiniti clearly has a lot to learn about this kind of technology. My 13 year old Acura has the same safety features and its never done anything like that!

We received the federal recall information and took the vehicle to the nearest Infiniti dealer (96 miles away) on 9/2/26. Diagnostics were performed and were told that the car "passed" the inspection. Two days later, the engine demonstrated complete failure. We had to have the vehicle towed to a Nissan dealer in our town (no Infiniti here) on 9/11/26. According to this report, " Based on the testing and findings, this no start condition relates engine mechanical issue, possible low compression from cylinders. Recent service history shows engine bearing inspection has been performed, and and engine ass'y has Infinity extended warranty". Due to the warnings of "catastrophic engine failure" per the federal recall, we believe this is a significant safety issue. We have learned of many pending cases of "inadequate diagnostics" and engine failure afterward. Currently we are trying to work with Infiniti to resolve this issue, and have filed a claim with Consumer Affairs with minimal response thus far. We are towing the vehicle back to the Infiniti dealer 96 miles away today, and are hoping that Infiniti will resolve this safety issue. We feel it is important to file this report due to the ongoing recalls, engine failures, and pending civil action. This has been a known safety issue for vehicles of this year, make, and model.

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.

#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.

ENGINE
My 2021 Infiniti QX50 has suffered a catastrophic internal engine failure. This vehicle is explicitly covered under active federal safety recall NHTSA Campaign 25V437000 (Infiniti Campaign R25A8/A9 / R25B1/B2) for defective, failing main and link bearings. The Infiniti dealership is actively refusing to honor the mandated federal recall remedy. The service department is attempting to illegally bypass the safety recall mandate by blaming the presence of engine sludge and claiming they do not visually see metal shavings. They are demanding that I pay out-of-pocket for a consumer-pay engine replacement. Under federal law, a manufacturer cannot deny a safety recall remedy based on vehicle maintenance history or engine sludge. Furthermore, the massive friction and overheating caused by the defective, failing recalled factory bearings directly causes and accelerates oil breakdown and sludge. The dealership is using the presence of sludge to mask a federal safety defect.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
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,

The vehicle has metallic noises in the engine and drastic loss of power, compromising safety on the road. The problem in the VCR actuator was verified by Infiniti Taverna ([XXX]) and denied the repair by the extended warranty by them of up to 120k miles (currently my car is at 98k). There is an injection light on the dashboard. It was reported to Infiniti USA and they also denied the repair. The vehicle is my only means of transport to serve my [XXX] son.

The power liftgate (automatic trunk) system on my 2019 Infiniti QX50 malfunctioned. After fully opening, the liftgate unexpectedly closed on its own without any warning beeps or resistance detection. This poses a severe safety risk. The heavy door struck my head, causing a physical injury (a severe bump/contusion). The vehicle and the affected components are available for inspection upon request. This problem has not yet been inspected, reproduced, or confirmed by a dealer, manufacturer, police, or insurance representatives, as I am reporting this dangerous safety defect immediately. Furthermore, there were no warning lamps, error messages, or any other symptoms prior to this sudden failure.
