Hey everyone,
I’m driving a 2019 Toyota Corolla Hybrid Touring Sports (Luxury Plus), and I’ve been chasing a really specific issue.
At exactly around 100 km/h, I get:
- a noticeable humming/whining noise
- slight vibration, mostly felt in the pedals/floor
What’s weird:
- It disappears below ~95 km/h and above ~110 km/h
- It happens even when coasting (no throttle)
- No real vibration in the steering wheel, mostly in the lower part of the car
What I’ve already checked:
- Switched from winter to summer tires - no change
- Wheels were balanced and I was told the rims are not bent
So at this point, it seems speed-dependent only, not engine load related.
Has anyone experienced something similar?
Could it still be tires (like road force issue), or should I be looking at wheel bearings, hubs, or something else?
Any ideas or similar cases would really help
