Honda Fit 2011 Hatchback 167222 km
Honda Fit 2011 has started making a humming or whining noise. When driving uphill, the car seems to lose power, but after a while it starts driving normally again. The harder the engine has to work, the louder the noise becomes. Some mechanics suggested that the problem might be coming from the transmission (gearbox). I also replaced the wheel hub bearing, but the noise is still there. Several mechanics have inspected the car, but nobody has been able to identify the exact cause of the problem. I would like to know what could be causing this noise and the occasional loss of power.
