| Suspension problems |
While driving in slow, heavy highway traffic, the vehicle suffered a structural failure of the rear crossmember / rear subframe due to severe rust. This is a safety-critical structural component and part of the rear suspension mounting system. When braking, the vehicle swerved hard to the right and crossed into the shoulder. Fortunately, the vehicle was already in the right lane, which likely prevented a more serious incident. The failure created a serious risk of loss of control and crash. After the incident, I took it straight to a mechanic on the way and the condition was identified as a broken rear crossmember caused by advanced corrosion. The failed component is available for inspection.
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.
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.

The electric controlled coupling failed and as a result, the awd failed. There is vibration when turning and driving 25 mph. The grinding noise remained after I got new brakes and I was told it’s from the coupling trying to power the awd. I took my 2016 Qx60 to the dealer and also to a foreign car auto shop and they both confirmed it needs to be replaced. When the coupling is unplugged, the noise is not present.
Took the vehicle in to the dealership for an oil change and state inspection. They informed us of the front lower control arms bushings are cracked, torn and need to be replaced. The vehicle is 5 years old with 41,000 miles. I asked the dealership why they would be this way and the service writer stated that it is just the quality of the bushings. Why are the bushings that worn on a vehicle that drives 8,000 miles per year, garage kept and all highway miles?.

Excessive corrosion and structural integrity failure of rear subframe - rust through and disintegrated into broken pieces with holes. 2014 - car only 7 years old, the structural integrity and safety issue of this failure should not occur in this period of time. Dealer quoted $4,600 to fix, and denied it should be covered under warranty.
Electrical coupling faulty and cause the car to shudder and jerk. I took it to priority infinity greenbrier it is a know issue. These coupling should last on these vehicles. Component has not been inspected by manufacture. No warning notice at all.
