Yeah. Gotta be way careful with Air Conditioning (A/C) system as well. If the car is facing a particular direction when parked, the sunlight can heat up the Air Conditioning condenser in front of the radiator. Hot in the day, cool at night. With this hot / cold cycle the refrigerant slowly migrates around the system. Unfortunately, your automotive air conditioner requires oil be cycled throughout the system to provide lubrication for the A/C compressor. If this goes on for a long time, all the oil in the system migrates to a single place, and the compressor will be absolutely dry of oil. If somebody starts up the air conditioning at high engine rpm, wham. Good-bye A/C. Have a nice day. I know Original Equipment Manufacturers (OEM) have seen this problem in the past for cars parked for an extended period of time (generally around 60 days or more.)
Unfortunately I don't really know the best fix.. I'd request the dealer to start the car up once a week and run the A/C at vehicle idle speed for a few minutes.
I would ask the dealer for a copy of their written procedure for storage of a customer's vehicle on the premises for a period of more than two weeks. I'd be willing to bet a steak dinner they have a written procedure. The dealer may not have one, but Honda OEM certainly should. If the dealer says they don't have a procedure, immediately ask for the name and telephone number of the regional Honda service rep who monitors that dealership.
And hey, for my steak, is Outback Steakhouse okay with you?
