Honda says that, if the 2011 Civics involved in the recall are involved in a rollover accident, a cracked roll-over valve might allow fuel to leak from the gas tank into the evaporative emissions canister. In extreme cases, this could cause a fire.
Of the recalled cars, 18,000 are in the United States and around 3,000 are in Canada. The recall affects vehicles built in Indiana, Ohio and Ontario.
Owners should receive a notice in the mail in the middle of next month. At that point, they will be instructed to visit their local dealer for a complimentary replacement.
