Service engine light. Leak in fuel tank.
I've had my 2003 wrangler sierah for 3 months and had the check engine light came on twice. First time was a purge valve solenoid and the second time it was the charcoal canister and the whole gas tank had to be replaced along with another solenoid. Neither of these failures left me stranded but should not have occurred on a jeep with less than 5000 miles on it.
