In 2013 we took r vehicle to get smoged it wouldn't pass the mechanic said there is a crack in the gas tank and they can use some stuff on it to patch it ,now a year goes by my son is using the car putting gas in the at the station and another lady tells him your leaking gas took it to the chevy in tracy CA they said there was nothing they could do there was a recall on this vehicle and they couldn't do anything about it and my husband told them we never received a recall notice about this and he said there was nothing they could do and it would cost us 1600. 00 now my GMC is setting in my driveway and we r too afraid to drive it that it will catch on fire and its undrivable the neck going to the gas tank is cracked , my son drove this vehicle with his baby for quite awhile and this has scared me to death I think GMC needs to make this right and fix this problem on my car we would of taken it in right away if we had know about it and that there was a recall.
