Looking at the documentation that went along with the recall announcement, GM has 60 days from the date they notify the NHTSA of the recall to notify owners. Whether this means the remedy needs to be determined by then or not is unclear but there will be a notification letter sent out to owners by April 9 unless GM gets an extension.
