So here is the latest on the gear meshing noise on my 2014 expedition limited with 29,000 miles on start up.
I have found the noise is coming from the air conditioner compressor. After vehicle sits overnight it will make the noise a few seconds after startup with the climate control set to Auto. Turning off the climate control the next day upon start up there was no noise until I turned on the AC. I have done this a number of times now, even recording the sound with my phone. Left the vehicle with the dealer for 5 days (due to an out of town trip) so the dealer could replicate the problem. Dealer said this was a known problem and verified by contacting the Ford Engineering Hotline. Fix was to check by Pressurize, check for leaks, discharge system, evacuate and recharge charge system leaving out 1 ounce of oil from the AC System. Said oil pooling overnight causes an abrupt hit to the system. Should fix the problem. The service manager was involved and said he expected a service bulletin to be coming out on this problem.
Of course it didn't as I had the same problem the next day so I again tested with the AC on and then off the next couple of days so I took the car back. Played the recording for them. The repair order states "GEAR MESHING NOISE ON COLD STARTS STILL THERE AFTER PERFORMING OIL REDUCING PROCEDURE PROVIDED BY FORD ENGINEERING HOTLINE. DIAG AND ADVISE. left the vehicle overnight so they could also hear from themselves.
The outcome Story: 29281 "NOISE HAS BEEN DETERMINED TO BE A NORMAL CHARACTERISTIC OF OPERATION. WE CANNOT MAKE A CORRECTION TO THIS AS IT IS INHERENT TO DESIGN. THIS IS NOT HARMFUL TO EITHER THE A/C COMPRESSOR OR ENGINE AND WE WILL STAND BEHIND THIS AS A NORMAL CONDITION."
I'm not buying this but what more can I do? Has anyone had a similar experience? Glad this is the AC and not the transmission as some have stated but still!! A $50K plus car that makes a noise when you first start it after sitting overnight? Anyone else having a noise problem and thinking its the transmission should check out starting with the AC off then on the next day. I usually leave my climate control on Auto all the time so thats why I didn't notice before.
