2016 QX60 CVT Shuddering and Whining - Is it failing?

Vehicle: 2016 Infiniti QX60 AWD

Hi everyone,

I own a 2016 Infiniti QX60 with about 90,000 miles, and I've started to notice a distinct shuddering sensation when accelerating, especially from a stop or at lower speeds. There's also a noticeable whining noise that seems to be coming from the transmission area, which gets louder with acceleration.

I've heard about issues with CVTs in some Nissan/Infiniti models, and I'm really concerned this might be a sign of a failing transmission. Is this a common problem for the 2016 QX60? What are the typical symptoms of a failing CVT in these vehicles? Any advice on how to proceed or what to expect in terms of repair costs would be incredibly helpful.

ClearTheCode admin answer:

The symptoms you're describing in your 2016 Infiniti QX60—shuddering and a whining noise—are indeed common indicators of potential issues with Continuously Variable Transmissions (CVTs) in certain Nissan and Infiniti models. The Jatco-supplied CVT used in the QX60 can be prone to wear over time, especially if maintenance isn't strictly followed.

Here's a breakdown of potential causes and what to do:

  1. CVT Fluid Degradation: The most common cause of CVT issues is degraded or low transmission fluid. CVT fluid is critical for lubrication, cooling, and hydraulic pressure. If it's old or contaminated, it loses its ability to perform these functions, leading to shuddering and excessive wear. Infiniti recommends specific CVT fluid (Nissan NS-3) and regular changes, often every 30,000-60,000 miles under normal conditions, or more frequently under severe use.
  2. Overheating: CVTs are sensitive to heat. If the transmission has been subjected to frequent heavy loads, towing, or aggressive driving, it can overheat, accelerating fluid degradation and component wear.
  3. Internal Component Wear: Over time, internal components like the belt, pulleys, or valve body can wear out. The whining noise often points to worn bearings or internal pump issues.
  4. Diagnostic Trouble Codes (DTCs): A failing CVT will often trigger codes such as P0740 (Torque Converter Clutch Circuit Malfunction) or P0776 (Pressure Control Solenoid 'B' Performance/Stuck Off). A professional scan can confirm these.

When to See a Shop:

  • Immediately: Continuing to drive with these symptoms can lead to complete transmission failure, which is a very costly repair, often requiring a full replacement. The shuddering indicates internal slip and wear, which will only worsen.
  • What to Expect: A reputable shop will first check the CVT fluid condition and level, then scan for codes. They may recommend a fluid flush and filter change as a first step if the fluid is in poor condition. However, if significant internal wear is detected, a transmission replacement or rebuild is often the only long-term solution. Be prepared for potentially significant repair costs, as CVT replacements can range from $4,000 to $7,000+.
