The bad news is that we still aren't exactly sure what is causing the problem with the brake release (or the lack thereof). There seems to be a delay between changing gears and the computer knowing that we have changed gears. There is also paperwork that says it can take up to 15 seconds for the release of the brake in cold weather. This, however, does not explain why pulling/switching the fuse 'fixed' the problem.
The good news is that the wonderful folks at Hal Burns only charged us 195.69 and told us we can stay plugged in another night and go enjoy Santa Fe in the daylight! David (Burns) also told us that if we should have any other problems with it and we can get back here that he wouldn't charge us another diagnostic fee and they'd work on it some more. He also assured us that we aren't doing any damage, and we aren't in any danger. Once the vehicle is running down the road the brakes will not just lock up on us. That is a relief.
Life is good and we are off to shop!
