ClearTheCode guidance (Infiniti · Brakes & suspension)

Summary: For Vibrations when braking in my 2017 Q50 3.0t – feels like warped rotors but new?, work through these steps on your 2015+ 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.

Owner reported: Hey everyone,

I've got a 2017 Infiniti Q50 3.0t and lately, I've been experiencing a noticeable vibration through the steering wheel and brake pedal when I apply the brakes, especially at highway speeds. It feels a lot like warped rotors, but I had the front brakes (rotors and pads) replaced about 8 months ago.

Could it be something else? The car has about 75,000 miles on it. I'm wondering if it…
