2018 Outback: Pulsating Brakes and Steering Wheel Shake When Braking

0

Diana O. · rep 0 · May 22, 3:16 AM · 1 replies · solved · Question

Hey everyone, I've got a 2018 Subaru Outback 2.5i Limited with about 70,000 miles on it. Lately, when I hit the brakes, especially from highway speeds, I get a really noticeable pulsation through the pedal. My steering wheel also shakes quite a bit.

It's not constant, but it's getting worse. I had the pads and rotors replaced about 20,000 miles ago at a local shop. Could it be warped rotors again already? Or something else entirely?

I'm trying to figure out if this is something I can check myself or if it's definitely a shop visit. Any advice would be great!

ClearTheCode guidance (Subaru · Brakes & suspension)

Summary: For 2018 Outback: Pulsating Brakes and Steering Wheel Shake When Braking, 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.
