2018 Outlander CVT Shudder and Hesitation - Is this normal?

Vehicle: 2018 Mitsubishi Outlander SE

Hey everyone,

I've got a 2018 Mitsubishi Outlander SE with about 75,000 miles on it, and I've started noticing some concerning behavior from the CVT. When accelerating from a stop, especially after the car has been running for a bit, there's a distinct shudder or vibration that feels like it's coming from the transmission. It also seems to hesitate a bit before engaging fully.

It's not constant, but it's happening more frequently now. I'm worried about the long-term reliability of the CVT. Is this a common issue with these Outlanders? I've heard mixed things about Mitsubishi CVTs.

Has anyone else experienced this? What did you do to fix it? I'm trying to figure out if this is something I need to address immediately or if it's just a characteristic of the transmission. Any advice on maintenance or what to look for would be greatly appreciated!

ClearTheCode admin answer:

It's understandable to be concerned about shuddering and hesitation from your CVT, especially as your 2018 Mitsubishi Outlander approaches higher mileage. While CVTs can have unique operating characteristics, persistent shuddering is often a sign that something needs attention.

  1. Common Causes:

    • Degraded CVT Fluid: This is the most frequent culprit. Over time and mileage, CVT fluid loses its lubricating and cooling properties, leading to increased friction and shuddering. Mitsubishi recommends specific fluid types (e.g., DiaQueen CVTF-J4) and regular replacement intervals, often around 30,000-60,000 miles, depending on driving conditions.
    • Software Calibration Issues: Sometimes, the transmission control module (TCM) software can cause or exacerbate these symptoms. Mitsubishi occasionally releases software updates or Technical Service Bulletins (TSBs) to address such issues.
    • Worn Internal Components: Less commonly, issues with the CVT's internal components like the drive belt, pulleys, or valve body can cause shuddering. This is usually a more serious and costly repair.

  2. What to Check:

    • Fluid Level and Condition: Check your CVT fluid level according to your owner's manual. Note the color and smell. Healthy CVT fluid is typically reddish-brown and doesn't have a burnt odor. Dark, burnt-smelling fluid is a strong indicator it needs changing.
    • Diagnostic Codes: Even without a check engine light, a professional scan tool can sometimes reveal pending or stored transmission-related diagnostic trouble codes (DTCs). Codes like P0741 (Torque Converter Clutch Performance) or other general transmission range sensor codes could point to an issue.

  3. When to See a Shop:

    • Immediate Action: If the shuddering is severe, accompanied by warning lights, or if the vehicle struggles to move, it's crucial to have it inspected by a qualified mechanic specializing in transmissions or a Mitsubishi dealership immediately. Continuing to drive with a significant CVT issue can lead to catastrophic failure.
    • Routine Inspection: For less severe symptoms, schedule an appointment to have the CVT fluid checked and potentially replaced. Inquire if there are any applicable TSBs or software updates for your 2018 Outlander's CVT. A professional can also perform a diagnostic scan and a road test to properly diagnose the issue.
