General Motors’ troubles with safety recalls has surfaced in another case, this time with the company recalling a group of SUVs for a third time to fix power window switches that can catch fire.

The problem, revealed in documents posted by federal safety regulators this week, is so serious that GM is telling customers to park the SUVs outdoors until they are repaired because they could catch fire when left unattended.

The vehicles will be left outside for a while. Parts won’t be ready until October at the earliest, according to GM. The automaker also has ordered its dealers to stop selling the SUVs as used cars until they are fixed.
