2024 Infiniti QX60

To Whom It May Concern, I am submitting this letter to formally report a safety-related defect involving my leased Infiniti vehicle, serviced at Edison Infiniti in New Jersey on August 1, 2025. Despite reporting excessive tire wear and a persistent pull to the right, the dealership concluded that the alignment was within factory specifications and attributed the damage solely to a lack of tire rotation. Based on this assessment, I paid out of pocket for a wheel alignment and replacement tires. However, the condition of the removed front tires tells a different story. The tires show extreme treadwear down to the internal cords, a clear indication of prolonged misalignment or defective suspension geometry. This level of degradation is not consistent with normal wear and tear on a vehicle with fewer than 17,000 miles. It compromised steering control and posed a serious safety risk, making it difficult to maintain lane position and safe handling. I believe this issue may reflect a broader defect in alignment or suspension geometry that could affect other vehicles of the same make and model. I have attempted resolution through the dealership and Infiniti Consumer Affairs without success. I respectfully request that NHTSA investigate this issue as a potential safety defect and advise on next steps.

The contact owns a 2024 Infiniti QX60. The contact stated that while driving at 35 MPH, the vehicle experienced electronic malfunctions with unknown warning lights illuminated. The vehicle was taken to the local dealer to be diagnosed, and it was determined that the dipstick was not properly in place. The vehicle was repaired. The contact stated that on another occasion, while driving at an undisclosed speed, the system malfunction message was displayed. The vehicle was towed to the same local dealer, where it was diagnosed, and determined that the battery needed to be replaced. The vehicle was repaired, but another failure occurred. The contact stated that the smoke alarm had alerted her to an issue. While the vehicle was parked in the garage and unattended, the engine overheated. The Fire Department was called to the scene and detected smoke coming from the engine. The internal temperature of the vehicle was 168 degrees. The vehicle was towed to the same local dealer, who determined that the vehicle had overheated, and the vehicle should be picked up. The manufacturer was contacted and opened a case. The failure mileage was approximately 32,000.

Dealer replaced my driver side mirror assembly a few months ago to get rid of the wind whistling noise, but we noted the "new" mirror would vibrate even at a fairly low speed. So took it back to dealer during the 15k mile service. The tech said the mirror had too much play so the dealer ended up replacing the whole mirror assembly. But the newly replaced assembly was also vibrating. Dealer said that there is not much they can do and asked us to call Infinity customer service. Customer service said that that vibration is considering within engineering spec and they are not willing to do anything about it. The vibration is very annoying - the shaking mirror is just a distraction.

On multiple 2024 Infiniti QX60 vehicles (test drives, my vehicle, loaner vehicle), the driver-side door rearview mirror glass vibrates under all driving conditions. This can blur the image and is unsafe during lane changes. Note that the passenger-side door mirror glass does NOT vibrate. It appears to be an isolator issue on only the driver-side door mirror. The problem was investigated and confirmed at an authorized Infiniti dealership (Coulter Infiniti) but they stated that all 2024 QX60 experience the same issue and it is normal. I stated it is not normal and a defect that needs to be addressed. There is currently no fix available.

In moderate to heavy rain, the windshield wiper pushes water onto the drivers side window. This water then streaks diagonally down across the window, blurring the view through the drivers side mirror. I experienced this in two cars, once on the test drive on [XXX] in Dublin, and once driving through the [XXX] in rainy conditions. Rain is when you need visibility to be good. I have not experienced this in any other car I have driven. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While at a stop in DRIVE, the car would automatically shift itself into Neutral without warning. When I contacted the dealer, they were aware of this issue in other vehicles. I brough the car in for service and in the description of the work, the mention that they knew where to address the problem, as it is a known issue. The dealership stated, "PREFORMED BATTERY PERFORMANCE TEST PER PREVIOUS TECH LINE CASES WITH SIMILAR ISSUES. BATTERY PASSED TEST WITH CPX900 AND DCA8000. CONTACTED TECHLINE AND WAS INFORMED TO CHECK FUEL PRESSURE AND FUEL PRESSURE BLEED OFF DUE TO SIMILAR CASES EXHIBITING SAME CONDITIONS. FOUND LPFP TO BE ONLY PRODUCING 45PSI AT IDLE AND IMMEDIATE BLEED OFF WHEN VEHICLE SHUT OFF. CAUSING CAR TO SHIFT INTO NEUTRAL AS FAIL SAFE * REPLACE LOW PRESSURE FUEL PUMP PER TECHLINE RECOMMENDATION"
