I am reporting a serious safety concern with my 2016 Infiniti QX60 involving a defective cooling fan system. The vehicle currently experiences a ticking/tapping noise from the cooling fan, and the fan does not operate properly, which has caused the engine to overheat. This condition creates a significant safety hazard, as engine overheating can lead to sudden engine failure while driving, increasing the risk of an accident. The issue also makes it unsafe to use essential features such as the air conditioner in hot weather and the defroster in cold conditions, which impacts visibility and driver safety. This defect appears to be part of a known issue affecting this vehicle platform, where the cooling fan system fails prematurely. I understand there have been allegations, including in Anderson v. Nissan North America, that the manufacturer may have been aware of this defect but did not adequately disclose it. In addition, I am aware that this vehicle model has been associated with other safety-related recalls, including issues involving the ABS actuator (which may pose a fire risk) and the hybrid powertrain control system (if applicable). These existing concerns further highlight the urgency of addressing this defect. This is not normal wear and tear, but a potential safety-related defect that places drivers, passengers, and others on the road at risk. I am concerned about continuing to operate this vehicle and potentially causing an accident or injury due to overheating or loss of vehicle function. I am requesting that this issue be formally investigated to determine whether a recall or corrective action is necessary to prevent harm.

While driving, the vehicle displayed an engine malfunction warning followed by a low oil pressure warning. I pulled over and waited. The oil level was checked and was not empty. The warning lights briefly went out, but shortly afterward the engine lost power. When attempting to restart the vehicle, the engine began knocking. The vehicle became inoperable and required towing. This was a sudden engine failure with no prior indication of oil loss, leak, or neglect. This created a safety concern due to sudden loss of power while driving.

2020 infinity qx 60 Bought car used in 2024 with 80,000. There is a hesitation when accelerating and sometimes seems to want to die when idling. There is also a knocking sound at times when accelerating. At times I feel transmission skips. When turning right or left or reversing, the wheels seem to creek and almost grind a bit. I am great about maintenance and called to determine if my vin was included in the current recalls. I am told no, but am experiencing the same symptoms described by infinity. Just want to know if there is a any action to take to ensure my 4 kids and I are always safe when traveling and dont end up with thousands in repairs.

My engine is making a knocking noise and wants to stall sometimes. Some other Nissan engines have recalls and I feel like it should include this engine. This is a 2020 and I still owe a lot of money. I should not be having major engine issues. Please look at this engine with the other recalls.

Check engine light came on, poor idling and start up. Infiniti replaced pvc hose that was cracked, electical seat warmer issue was fixed, dvd electrical issue was denied under the claim warranty, and some sensors were replaced due to codes of lean fuel, and the technician noticed a ticking noise. The dealership told us to pick the car up, drive it and put more miles on it and bring it back in to file another claim for the ticking sound. Returned to file new claim and was told the engine needed to be replaced or timing chain should be replaced due to sludge in the engine even with proper maintenance [records submitted to dealership for warranty claim which was denied]. Passanger seat warmer had also gone out since our last visit, so they're fixing that electrical issue as well. [We were denied for driver side electical window repairs, as they said components were "only loose"]. We purchased the Elite Protection Plan that should have covered all issues but they are denying the claim. Main concern is the engine as there are multiple forums and social media groups that are complaining of the engine sludge issue on new or certified Infiniti or Nissan vehicles with the same engines. Most owners are providing service/maintenance records and still being denied engine repair or replacement under warranty. These engines need to be recalled and consumers need to be compensated for their time and repairs.

Vehicle began ticking in early 2023. Then received check engine light and trouble codes P0014 and P0017. Took to Infiniti dealership. Dealership claimed "sludge - you did not change oil regularly, " which I did - either at Valvoline, Wal-Mart, or by myself. Multiple online forums about Infiniti QX60 indicate all the dealership mechanics are saying the SAME thing to customers who are having this issue. Dealership claimed vehicle would need NEW engine priced at over $17,000!! They are doing this nationwide and globally. Infiniti KNOWS there is an engine defect leading to sludge and failed engine. My engine did fail in April 2024, but thankfully in my home driveway and not at high speeds - this would have been deadly had it happened on a major highway!

Hello the CVT transmission in these 2014-2017 vehicles have been known to be defective. Apparently Infiniti settled a lawsuit that was suing them for this exact reason. They settled without admitting fault. Problem with that is all these vehicles are still on the road and customers are unaware. They say they informed us but I can assure you I never was informed. They also sent a service bulletin to their dealerships telling them to expect problems and to fix if brought in. The vehicles are dangerous without a doubt. They shake, shudder and lose acceleration with no warning. No lights come on the dash or anything. Someone will lose their life, if they haven’t already. The law firm had company emails showing they were going to do a recall. Corporate greed is my guess, got in the way. Now unsuspecting customers are driving ticking time bombs. Also owners are trying to sell these vehicles to unsuspecting customers. There is no way this should be acceptable in my opinion and am extremely disappointed with the lack of concern I’ve received from the company. We are paying for a so called “luxury” vehicle only to find out later that the transmission should of been recalled years ago. Here I sit with my 20k used vehicle blue book broken down car now. It’ll cost $9800 to fix. Just isn’t right and I hope I’m finding someone that will at minimum look into it. Please, do us all a favor before it’s to late. Thank you.
