Parking brake - unintentional release
2003 type-s, manual transmission. To make a long story short, I now understand the origin of vertical gouge in the rear bumper. I also understand why at rare times over the years there appeared to be more room in the front of the garage.
The electronic parking brake MYSTERIOUSLY disengaged. When I was lucky, the car only rolled a few inches...less lucky, and it rolled into the garage door. When door was subsequently raised it left a 4" gouge in bumper. This last time I was not lucky at all.
Door was up and car rolled out of garage, knocked over a tree, ripped out the fiber composite under pan before landing in a ditch. While pulling it out of the ditch the rear bumper was further destroyed and trunk lid bent.
A day or so later the check engine light came on along with the check fuel cap message. Turns out the evaporative emission lines from the engine compartment to the fuel tank were mangled and pulled out.
While the car did undergo the parking brake recall some years ago, that was for unintentional engagement. My situation is the opposite. Having a manual transmission wherein the car could be left in neutral means that when one removes the key, while the parking brake is automatically activated, there is no fail safe backup as with an automatic transmission being put into park. (my wife finally now understands why she has to leave the car in gear when parked)
Since there are so few manual transmission type-S cars out there, I am trying to find out if this has happened to others and, the extent of this problem, is it a known defect, etc. Thus far I have turned up nothing. Never got a brake warning message, brake was fine before and after.
When I dropped the car off at the body shop yesterday, aside from being told how few manual transmission cars he gets to repair, I was also told that he repaired a X-type a few years ago for the same thing. There the people were sitting in their yard and watched to their amazement as their car rolled into a tree.
Any info would be appreciated.

I would check the parking brake mechanism at the caliper. This is the first I've heard of a problem like yours. So, my guess is since you get no fault message, the car thinks the parking brake is engaged. The brake works by twisting down the pads onto the rotor. When the motor senses enough Resistance, it assumes the pads are securely clamped down on the rotor...So... If there is an issue with any of the mechanics it may not be clamping down all the way... Just my guess..

I'll throw this out for consideration. There is a procedure for resetting the parking brake after the battery is disconnected or replaced. It is fairly simple, and detailed in the owner's manual. Perhaps this needs to be done. I made sure the dealer did it for mine after the battery replacement. I would be happy to detail it for you, but am out of town, and away from the manual.
