Crack in gas tank discovered after several removals of tank to replace hoses, then clamps. Replaced 1998 tank with used tank from 1996 model. Within 3 month replacement tank was leaking from crack in same area as before. Discovered recall on this model and took vehicle to local dealer. Dealer refused to honor recall due to service performed in 2006 where they (supposedly) added check valve to prevent gas tank cracks from developing. Appeals to regional and national hyundai offices were also rejected. Dealer sent me away with seriously leaking / dangerous tank. *tr

Tl*the contact owns a 1998 hyundai sonata. The contact smelled gas and noticed a gas leak coming from the fuel tank. Recall # 00v314001 (fuel system, gasoline:storage:tank assembly) was found. The dealer stated that there was a hole in the gas tank, but refused to repair it because the vehicle was not included in the recall. The contact felt they should replace the gas tank as stated in the recall. The current and failure mileages were 117,000.

We purchased a used 1998 sonata gl for my daughter in may 2006. In about july 2006 she noticed that she seemed to be using more fuel than usual. Also that her and her friends noticed a strong smell of gasoline. Checking under the vehicle i notice that the fuel tank was wet on the drivers side near the rear tire and smelled of gasoline. We took the car to be repaired. The mechanic upon removing the tank noted that on the top left of the tank (if you were facing the rear of the car) had been patched previously with some kind of epoxy. We have no idea when this repair was done. He attempted again to repair it with epoxy, this was unsuccessful. He then replaced the tank with a used fuel tank from another hyundai. This was also unsuccessful. He then welded the spot on the tank. This was also unsuccessful as the tank started leaking again from the same area. We checked with a dealer and found that the vehicle had been in and had a fuel lined or hose replace on or about march 29, 2001. According to the nhtsa campaign 00v314001 a note: this was six years ago in 2000-2001. This cracking and leaking of fuel is still an unresolved issue as noted in the note: what has been done? What is the update? It has been six years. This is a know problem of this fuel tank and hyundai is aware of it. They have had plenty of time to research and come up with a safe resolution to this dangerous cracking of the fuel tank. This portion of the campaign should have already been resolved and must be soon. The following is the note from campaign 00314001: nhtsa campaign id number : 00v314001 make / models : model/build years: hyundai / sonata 1997-1998 **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. *nm

My 1998 hyundai sonata has been a challenge to maintain. Twice the driver's side door spring has rusted through and window regulators have failed. This particular incident was a fortunate stop in the car shop to check something else. They discovered that the rack and pinion unit was leaking power steering fluid. I had been complaining to the mechanic that the car "clunked" in the front end going over a bump. This despite replacing the ball joints, struts and one tie rod. It seems that the clunking noise must have been coming from the rack and pinion. They also discovered at the same time that two out of four engine mounts were cracked and the other two were sagging. I'll be replacing those as well and hoping that the car doesn't cause any further problems for a while. I believe in maintaining my cars, but this car seems to have had more problems than most i have owned. The car has also overheated twice, once due to a burst hose and the second time due to a leak in one of the engine coolant temperature sensors in the block. For the latter incident there was absolutely no warning (gradually increasing operating temp over time). It also has the hard down shift from 3-2 (automatic transmission) that others have noticed. I won't be purchasing a hyundai again as i feel that this is way too many problems for a car with only 90,000 miles on it.
