Q. My EcoSport is making sounds while driving on speed breaker. What is the problem?

My new ford ecosport ambiente model also make a sound of a motor revving up while driving from time to time. Service workshop has not yet been able to fix the problem. They suspected the ac and put some spray to lubricate it but the sound is still coming and it comes unexpectedly while driving. The sound is like an electric motor revving up. Any clues as to what might be the problem. The sound is coming from inside the cabine and not from the engine bay

For that, we'd suggest you to please visit the nearest authorized service center of Ford as they would be able to assist you better after the inspection of your vehicle. Follow the link and select your city accordingly for service centers.
