2024 Integra A-Spec CVT Shifting Weirdly - Jerking and Hesitation

Vehicle: 2024 Acura Integra A-Spec CVT

I just got my 2024 Acura Integra A-Spec with the CVT a few months ago, and I'm already experiencing some strange transmission behavior. It's got about 6,000 miles on it. Lately, I've noticed it jerking or hesitating when accelerating from a stop, and sometimes it feels like it's 'slipping' before catching, especially at lower speeds.

There's no Check Engine Light on yet, but it definitely doesn't feel right. It's not a consistent issue, but it's happening more frequently. I'm worried about potential long-term damage. Has anyone else with a new Integra CVT experienced anything like this? What should I be looking for or telling the dealer?

ClearTheCode admin answer:

Experiencing jerking, hesitation, or slipping sensations from the CVT on a brand new 2024 Acura Integra A-Spec with only 6,000 miles is definitely not normal and warrants immediate attention. Even without a Check Engine Light, these symptoms indicate a potential issue with the transmission's operation.

Here's what could be causing these symptoms and what steps to take:

  1. CVT Fluid Level/Condition: While unlikely on such a new vehicle, an incorrect CVT fluid level (either too low or overfilled) or contaminated fluid can cause shifting issues. A dealership will check this as part of their diagnostic process.
  2. CVT Software/Calibration: Modern CVTs are heavily controlled by software. There might be a known software glitch or a need for a re-calibration of the transmission control module (TCM). Acura may have technical service bulletins (TSBs) for such issues.
  3. Transmission Sensors: Sensors within the CVT (e.g., input/output speed sensors, pressure sensors) provide critical data to the TCM. An intermittently faulty sensor could cause incorrect fluid pressure or pulley ratio adjustments, leading to jerking or hesitation. These might not always trigger a CEL immediately.
  4. Internal CVT Components: In rare cases, there could be an issue with internal components like the drive belt, pulleys, or valve body. Given the low mileage, this would be a manufacturing defect.

What to Tell the Dealer:

  • Be Specific: Describe the exact conditions when it happens: from a stop, at what speed, under light or heavy acceleration, cold or warm engine.
  • Frequency: Note how often it occurs and if it's getting worse.
  • No CEL: Emphasize that there's no Check Engine Light, as they might initially dismiss it without a code.
  • Safety Concern: Express your concern about the vehicle's reliability and potential safety implications.

When to See a Shop:

Since your Integra is under warranty, your first and only step should be to take it to an authorized Acura dealership. Do not attempt any DIY diagnostics or repairs, as this could void your warranty. Insist on a thorough inspection and road test by a factory-trained technician. Document all your visits and communications with the dealer. This issue needs to be resolved under warranty to prevent future problems and ensure the longevity of your transmission.
