I purchased the 2010 Hyundai Santa Fe new with only 60 miles on it in June 2010. In January 2011 we began smelling a fuel smell. This occurred only after the car was running and shut off then subsequently turned back on less than an hour later like when running errands. I never smelled gas if the car sat overnigt. We also would experience an intermittent long crank. I brought the car to the dealer in January 2011 and they replaced 2 o-rings that they stated were leaking and found fuel around. After these were replaced, I still had the same problems. I brought the car back in February 2011 and no known problems were found by the dealer. Again, I brought the car back in March. This time they found fuel in the charcoal canister. They stated I was overfilling the tank which was why there was fuel in the charcoal canister. After speaking with the manager, they agreed to cover the part and labor at no charge and replaced the charcaol canister. After this was replaced, I no longer experienced the long crank but I still smell gas after running errands. Hyundai will again be looking at the car for any other problems, but the dealer is really stumped so far on this.
Gas/fuel smell coming from engine compartment into cabin of 2010 Hyundai Santa Fe GLS (2. 4 l automatic). Smell is not noticeable at cold start overnight, or after a couple of hours of sitting. Smell is very noticeable after the vehicle is driven to operating temperature and then shut off for anywhere from 10 minutes to an hour. The fuel smell comes directly into the cabin when the hvac system is set to vent, but not on recirculate. Dealer has removed and replaced fuel injectors and fuel rail. Smell still persists. This is a daily occurrence. The smell also occurs when stopped for any amount of time while driving/idling. The smell occurs when the vehicle's engine is off, but the key is turned to the point the hvac will turn on. This means the smell occurs regardless of whether the engine is running or not. The smell accumulates under the hood and is strongest near the passenger side middle. The smell is bad enough to permeate clothes while driving and to be smelled inside the house when the door to the garage is opened. It's bad enough to force parking the vehicle outdoors. It appears this issue is being discussed on the Hyundai forums website and most complaints are for the Hyundai sonata and sonata turbo, but the description of the issue and potential solutions point to the same cause for my Santa Fe. The dealer has acknowledged the smell, but not in writing. The vehicle has been in five times for this complaint - twice with work done, twice with no work done (claim was could not replicate), and once I was sent home before any work was done as the service representative determined there was nothing they could do at that time. There appears to be no known solution to this issue coming forth from Hyundai at this time.
When pushing the gas pedal to accelerate from stopped position there is a notable pause. (1-3 seconds??)this then causes you to push accelerator further ,thereby causing a much more sudden acceleration. I am used to it because it has happened intermittently since car was new, but someone could get in trouble. Hyundai service says its because the pedal is sending a position of pedal through an electronic signal to fuel metering system.
