Sound Coming On Crossing 120km/h Speed,Chevrolet Spark

[Shubham Gupta]

Chevrolet Spark ,2009,47k,petrol

While Driving at Speeds More Than 120km/h ,there is Hmm-Hmm or Hunn-Hunn Like sound coming from the car ,not a Continous one but like in a Cyclic Pattern .It only comes after crossing 120km/h speed and When i put the foot off the Accelerator Pedal at 130km/h then it stopped, but as i again pressed the accelerator at 120, it again started.
Below 120km/h there is no problem with and without accelerator. .

This sound is absolutely normal 120km/h is warning indicator for 800cc engines. You can notice high speed indication lamp in your cluster board if you touch 120km/h speed.

Shubham Gupta If you felt a slight vibration in you steering as well, your wheels are out of balance and need balancing, else it could be 'tyre noise' or the wheel bearings. If the wheel bearings are shot, they will become more audible in lower speeds as well as it gets worn down the line. so don't change in a hurry if it is indeed the bearings.

Sound will come as spark is an 800cc car and not meant for going on such speed
