Engine complaints dominate the 2013 QX56 owner reports, with timing chain failure being the most consistently described issue. Owners report hearing a loud ticking or rattling from the engine at startup, often accompanied by a flashing check engine light, misfires, and noticeable shaking while driving. The problem tends to surface at higher mileages but owners frequently note their vehicles were well-maintained, suggesting the failure isn't simply a result of neglect. In several cases the vehicle had to be towed after the symptoms appeared. Suspension complaints form the second-most-reported cluster, where owners describe the rear of the vehicle sagging or sitting lower than normal. That pattern traces back to the air suspension system, with diagnoses pointing to failed air shocks and a failing compressor. A smaller group of powertrain complaints rounds out the picture but at notably lower volume than the engine and suspension categories.

By System
The 2013 Infiniti QX56 has two recalls, the most serious being a driver's airbag inflator that can rupture during deployment and send metal fragments toward the driver and other occupants.
The second recall affects the fuel system on V8 engine models: a fuel pressure sensor that was not fully tightened during production can loosen over time and cause a fuel leak, which raises the risk of a vehicle fire if the leaking fuel reaches an ignition source.
