Monday evening the SO and I bought a 2002 Sonata from a dealership. That evening, we filled the tank and drove it home. Tuesday afternoon, after driving 85 additional miles, the check engine light came on.
We didn't even go home - we went straight to AutoZone to have the codes read. It came back with a "Large" Leak in the Evap System. The AutoZone boy ran down some of the common offenders but, since we'd just filled the tank on the car, we tightened the gas cap, called the dealership to report the problem and drove it around.
Cut to this morning on my way to work when, after 191 more miles, the light came back on. The SO took it back to AutoZone and got a code of P0442 - "Small" Leak in the Evap System. We haven't refueled or touched the gas cap since we cleared the code the first time around.
"The possible errors are...Defective, missing, or loose fuel cap.....EVAP Canister or hose cracked-not connected.........Purge Vent Solenoid defective...........Vacuum leak at engine."
Conventional wisdom says to actually replace the gas cap, unhook the battery to clear the code and drive it around for a few more days to see what happens because it's possible the seal on ours is just that bad and I'm all in favor of that - except that the State of Wisconsin affords car buyers 72 hours to return vehicles - no questions asked. I haven't had time yet to look into how long it gives you if the car is not in the condition stated on the bill of sale, but the impression I get is that I don't have much of it. I have a call into the dealership that sold the vehicle in hopes that they won't fight us on having their mechanic take a look at it without charging us, but I'm not holding my breath.
If we have to fix this ourselves, can anyone tell me what the likely culprits might be given this model? I know there was a recall on the Fuel Assembly Valve - I doubt it's related but if the VIN still needs the work, we'll take it into the nearest Hyundai dealership and hope the mechanic stumbles on the solution to our other problem if we have to :P
Also, I so sympathize with the poor little blue guy - because that's what car shopping has been doing to me :P :boink:
