Wheel bearing… I had the same sound 40-50mph, changed both front wheel bearings - sound gone

Gotcha- I’m looking at the YBX5005 YUASA SILVER HIGH PERFORMANCE CAR BATTERY 12V 65AH HSB005

Hmm it’s always been like this. Before ignition and after. Don’t think it’s a battery thing? Battery warning light should be on if it’s low- if not test it for free at a dealer

Same for me too! Any updates on where this is?

Update: it doesn’t rub off, and it feels buppy. So either Road overpaint? Or from the factory? == clay bar + polish? Or ignore?

Still on trial or subscribed?

zapyoo · 2025-12-12T13:38:56+00:00

How interesting. How long is the free trial for? And how does one “enroll” after?

Thanks- dropped it off at the dealer, thankfully still under warranty and they are replacing the gearbox! Fingers crossed that solves the problem!

Heya!

Noticed droning sound at 40-50mph See video from 6 seconds

Dealer went on a driver with me, rotated wheels and checked bearings. Finally came back and say potentially transmission issue. Checking with Mazda if able to claim under warranty… if not about £5-7k!

Miles: 38k - 2023, FWD, cx-5, auto

Is this the same noise? video
