2017 QX60 CVT Hesitation and Jerking - Is this normal or a problem?

Vehicle: 2017 Infiniti QX60 AWD

I recently bought a used 2017 Infiniti QX60 AWD with about 55,000 miles on it. Overall, I love the car, but I've noticed that the Continuously Variable Transmission (CVT) sometimes hesitates when accelerating from a stop, and there's an occasional jerking sensation, especially at lower speeds or when coming to a stop.

It's not constant, but it's concerning me. I've heard mixed reviews about Infiniti CVTs, with some people saying they're just 'different' and others reporting major issues. Is this just how they are, or should I be worried about a major transmission problem developing?

Are there any known recalls or service bulletins for the 2017 QX60's CVT that address these kinds of symptoms? I want to make sure I'm not ignoring something serious.

ClearTheCode admin answer:

It's understandable to be concerned about your 2017 Infiniti QX60's CVT behavior, as these transmissions can have unique characteristics. Here's a breakdown of what you're experiencing:

  1. CVT Characteristics vs. Issues:

    • Normal: CVTs often have a different feel than traditional automatics, sometimes exhibiting a 'rubber band' effect or slight hesitation as the ratio adjusts. A very subtle, smooth engagement from a stop is typical.
    • Concerning: Persistent jerking, shuddering, or significant hesitation, especially when accompanied by unusual noises (whining, grinding), a burning smell, or a 'limp mode' where the car struggles to accelerate, are signs of potential problems.

  2. Potential Causes for Your Symptoms:

    • Fluid Degradation: CVT fluid is critical and needs regular replacement (typically every 30,000-60,000 miles, depending on driving conditions). Old or low fluid can cause hesitation and rough operation.
    • Valve Body Issues: Problems with the CVT's valve body can lead to incorrect pressure regulation, causing jerking or delayed engagement.
    • Torque Converter Lock-up: Issues with the torque converter clutch can cause shuddering. This might trigger codes like P0741 (Torque Converter Clutch Circuit Performance or Stuck Off).
    • Software Glitches: Sometimes, a simple software update can resolve minor drivability issues.

  3. TSBs and Recalls: Infiniti has issued several TSBs over the years related to CVT performance, drivability, and software updates for various models, including the QX60. It's worth checking with an Infiniti dealership to see if your specific VIN has any outstanding service campaigns or software updates that could address your symptoms.

  4. When to See a Shop: Given your concerns, it's highly recommended to have your QX60 inspected by an Infiniti-trained technician. They can perform a diagnostic scan for any stored trouble codes (even if the check engine light isn't on), check the CVT fluid level and condition, and assess the transmission's overall health. Addressing potential issues early can prevent more costly repairs down the road.
