I brought my 2014 Civic in for its regular maintenance service appointment and was asked if there was anything else of concern...I mentioned that when pressing on the accelerator, especially after shifting gears that there was a 'clinking' sound. I was informed that it was because of my after-market floor mats. The removed my driver's side mat and said that it was fixed. Upon driving my vehicle home from the dealership, the vehicle continued to make the same 'clinking' sound.
