Two weeks ago, I bought a Swift 2013 and today, when driving on a highway at 75 mph at 4th gear, the car jerked softly. When I tried to change it to 5th gear, I noticed revolutions could not be changed and it remained at 4th gear for a while. When it finally changed to 5th, the jerks disappeared but the engine lost power. After some time driving, the engine service symbol turned on and, when reducing the speed to park the car, I felt as if the car were about to stall and it vibrated considerably. The car was towed to the agency where I was told it was posibly a problem with the spark plugs. The vehicle was scanned and it was indicated that there was a starting failure. I would like to know if someone had this inconvenient. Thanks.
