I bought a new 2014 Mustang GT with 300 miles on June 28, 2014 from a dealer in Iowa and noticed a "ticking" noise almost immediately upon arriving home in Wisconsin. Because it was inconsistent I quickly dismissed it. However, upon taking it to my local dealer on Mon, Oct 20 for it's second oil change I mentioned it and asked them to look into it. Boy, did they ever.
Summary of events:
Mon, Oct 20 I dropped her off at the dealership for an oil change and requested they look into the "ticking" or "tapping" noise. Link to video: https://app.box.com/s/5e1u8icke1ibmm8woi0t
Wed, Oct 22 I called because they still had my car and they told me that they had pinpointed the noise to the passenger side of the engine.
Thu, Oct 23 I stopped by and talked to the service manager who told me that all the compression checks are normal, power balance tests passed and there are no codes. However, the interesting news was that when they cancel cylinder #3, by disconnecting the injector, the noise goes away. Furthermore, it's at this point they went forward with the oil change and they found metallic glitter in the oil as well as a couple of small metal pieces in the oil filter. I was told they had to wait to hear from Ford before proceeding further.
Fri, Oct 24 They called me and asked me if I wanted the car for the weekend - "Heck Yeah" so I popped in and picked it up.
Mon, Oct 27 I returned the car to the dealer before leaving on a business trip.
Thu, Oct 30 I stopped by and took a photo of the top of the motor which was torn down.
The next day, Oct 31, the motor was out of the car (another photo).
Then on Mon, Nov 3 we got a good look at the piston damage plus scoring on both cylinder head cam caps as well as cylinders #3 & #4 (see photo). There was also shading on cylinder walls on most of the cylinders.
Wed, Nov 5 the Service Manager called me and told me he had completed cost cap analysis and Ford agreed to replace the engine.
Thu, Nov 13 I picked her back up with a brand new engine.
Moral of the story: Don't let your dealer tell you that "ticking" or "tapping" noise is nothing and try to dismiss it. Be persistent and insist that they diagnose the problem.
Good luck!
