2018 Forester CVT Hesitation and Jerking at Low Speeds

0

Steve N. · rep 0 · May 22, 3:20 AM · 1 replies · solved · Question

My 2018 Subaru Forester 2.5i Premium, with about 75,000 miles, has started acting weird. When I'm driving at low speeds, especially in stop-and-go traffic, the transmission feels like it's hesitating or even jerking a bit. It's not a smooth acceleration from a stop anymore.

Sometimes it feels like it's struggling to find the right 'gear' even though it's a CVT. It's particularly noticeable when I'm trying to gently accelerate after slowing down, like in a parking lot or a drive-thru.

I'm worried about the long-term reliability of the CVT. Is this a known issue for this model year Forester? What should I be looking out for, or is this something that needs immediate attention from a mechanic?

Summary: For 2018 Forester CVT Hesitation and Jerking at Low Speeds, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
