2018 Outlander Sport CVT hesitation and jerking at low speeds

Vehicle: 2018 Mitsubishi Outlander Sport ES

Hey everyone,

I recently bought a used 2018 Mitsubishi Outlander Sport ES with about 60,000 miles on it. Overall, I love the car, but I've started noticing a weird hesitation and jerking sensation, especially when I'm starting from a stop or driving at very low speeds, typically under 20 mph. It feels like the transmission is struggling to engage smoothly, almost like it's slipping or unsure what to do.

It seems to happen more frequently when the car is cold, but I've experienced it even after driving for a while. There are no warning lights on the dashboard, and the car otherwise drives fine at higher speeds. I'm a bit worried about this, as I know CVT issues can be expensive.

Is this a common characteristic of Mitsubishi CVTs, or should I be genuinely concerned? Are there any known TSBs (Technical Service Bulletins) or common fixes for this model year? What should I tell my mechanic to look for when I take it in? Any advice would be greatly appreciated!

ClearTheCode admin answer: It's understandable to be concerned about unusual transmission behavior, especially with a CVT. While some CVTs can have a slightly different feel compared to traditional automatics, noticeable hesitation or jerking, particularly when starting from a stop or at low speeds, is not typically considered normal operation and warrants investigation.

Here are some potential causes and steps:

  • Degraded or Low CVT Fluid: This is a very common culprit. Over time, CVT fluid can break down, losing its lubricating and friction-modifying properties. Low fluid levels can also cause pressure issues within the transmission.
  • Transmission Control Module (TCM) Software: Mitsubishi, like many manufacturers, occasionally releases software updates for the TCM to refine CVT operation, address minor glitches, or improve shift logic. A dealer can check if your specific VIN has any applicable updates.
  • Worn Internal Components: While less common for a 2018 model unless it has very high mileage or has been subjected to severe use, internal components like the CVT belt, pulleys, or torque converter could be showing early signs of wear.
  • Sensor Malfunction: Sensors like input/output speed sensors or pressure sensors provide critical data to the TCM. A faulty sensor could lead to incorrect control signals, causing erratic behavior.

What to do and when to see a shop:

  1. Immediate Action: You should have this checked by a qualified mechanic or a Mitsubishi dealership as soon as possible. CVT issues can quickly escalate from minor annoyances to major, expensive repairs if left unaddressed. Early diagnosis is crucial.
  2. Diagnostics:
    • Fluid Check: Have the CVT fluid level and condition thoroughly inspected. Note that checking CVT fluid often requires specific procedures and temperatures.
    • Scan for Codes: Even without a check engine light, a professional scan tool can reveal pending or historical diagnostic trouble codes (DTCs) related to the transmission (e.g., P0700 for general transmission malfunction, or more specific codes like P0741 for torque converter clutch issues if the problem progresses).
    • Road Test & Data Logging: A technician should perform a road test while monitoring live data from the CVT, such as line pressure, gear ratio, and sensor readings, to pinpoint anomalies.
  3. TSBs: Ask the dealership to check for any Technical Service Bulletins (TSBs) specifically for the 2018 Mitsubishi Outlander Sport regarding CVT performance or hesitation. These are manufacturer-issued advisories for known issues and their recommended fixes.

Regular CVT fluid changes according to Mitsubishi's maintenance schedule are crucial for the longevity of these transmissions.
