At first they said it was some sort of battery that had gone bad causing the instrument cluster to reboot. Then they ended up replacing the entire instrument cluster. Then they couldn't program the new instrument cluster into the computer. Then they replaced the computer hoping that it would allow the instrument cluster to program. No go. Now they're replacing the computer again, claimimg that the 1st replacement computer was bad.
I think they have no clue what the problem is and they're just replacing things hoping that something would work. I bet that when I get the car back, it would have more problems than when I originally brought it in.

mtang,
sounds like you have a short circuit in the main wiring loom. This component is fed through the bulkhead during manufacturing. During this process the wiring loom is inserted into a protective sheath to prevent any chafing or cuts on the wiring harness when fed through the "razor edged" apperture of the bulkhead. I worked at Land Rover in the UK and witnessed a similar problem on a massive scale during 1st phase production on Range Rover (L322) a defect that was identified to the main wiring harness which supplies power to all the main vehicle functions and which unfortunately resulted in the cars affected (1,000's) being completely stripped out (Cockpit, seats, consoles, headlining, carpets, etc, etc) to replace the main wiring loom.
Sorry to give you the bad news
