Vehicles Affected
NHTSA Campaign #
Vehicle description: Accent GT model vehicles equipped with DOHC engines manufactured from December 19, 1996 through June 30, 1997; 1998 accent model vehicles manufactured from May 6, 1997 through June 25, 1998; 1997 Sonata vehicles manufactured from August 1, 1996 through July 9, 1997 and 1998 Sonata vehicles produced from July 9, 1997 through April 24, 1998. The evaporative emission control systems may apply excessive vacuum to the fuel tanks during the canister purge cycle. Minor fuel tank distortion could result. A small crack could develop on the upper fuel tank surface. The "check engine" light would then illuminate and, in some cases, the vehicle driver could notice a gasoline odor.
Dealers will pressure check the vehicle's fuel tank to determine if it has cracked. If it is cracked, a new fuel tank will be installed. A new fuel filler cap that decreases the amount of vacuum inside the fuel tank will also be installed. Note: The 1997-1998 Sonata fuel tanks have also experienced cracking. However, at this time, the cause for the cracking has not been identified. This portion of the campaign will begin after Hyundai has determined the cause and corrective procedure.
