The only reason the hole is there is because the car has to be in PARK to be started. Putting it in park presses on a switch that "turns on" the starting curcuit. Sometimes, however, the switch fails. That would leave you with a car you couldn't start, even to drive it down to the service center for repair. So they give you a way to bypass that broken switch. That's what the hole is there for.Why would they delete the hole? Perhaps they re-engineer the starting sequence, and eliminate the potential of the auto/park switch ever failing. Perhaps they move the location of the bypass switch just so people will stop asking "what's that hole for?". I suspect there could be dozens of reasons to delete the hole. But we'll just have to wait to see if newer Vibes actually don't have one. Then we can simply ask GM/Pontiac/toyota why they deleted it.OpalBlue
