Question about 2008 Hyundai Sonata

1 Answer

Fuel door indicator light remains on.

The fuel door indicator light came on after filling the car with gas. I took it to the dealer and he said it is supposed to stay on, it tells you that you have a fuel door release on the door. This is bull, as the light wasn't on before.

You may have one of the following.

A loose gas cap - remove cap and re-tighten again to see if light goes out (may take a while before light goes out)

A faulty gas cap - replace with a new one (shouldn't have failed yet if your car's only a year old)

A faulty fuel sensor only if your fuel level also shows as low (shouldn't have failed yet if your car's only a year old)

There's a vacuum leak somewhere (this would also trigger a check engine light)

Light says 367 miles to empty on dash


This is a readout of the estimated miles remaining in the current tank of gas. It is based on miles traveled since last fill-up versus fuel remaining in tank. Don't trust it, but is can give you indication of your approimate fuel economy.

How much fuel is left when the low fuel light comes on


It varies for every car. Usually 1-1.5 gallons when the low fuel light comes on. I drove my last '93 Ford Taurus around until the gauge said it was empty. Lifted the car and took the gas tank off and it had 3 or more gallons still in it. Here's some fun, zero your odometer, fill the gas tank and drive it until the low fuel light comes on. Then drive it till it dies out, obviously somewhere near home or where someone can drop off a full gas can.

Just purchased a used car from a respective car dealership in the area I reside. I had to take the car back to the dealer I purchased it from to have them look at the gas tank, due to gas just spewing out...


There's a very minor vacumn leak somewhere in the fuel system, it's most likely the cap as stated. If the codes keeps comming back, go see the dealer that fixed the fuel tank problem about it. You should let them know your having trouble with it.

2006 Chevrolet Aveo Check engine light comes on when under 3/4 tank fill it back up and the check engine light shuts off. What could be the problem?


I would first suspect that the gas cap is losing its seal, which happens to take about 1/4 tank of driving perhaps. The fuel tank, like most cars today, works on a closed system with a return and the air above the fuel needs to remain slightly pressurized.

The gas cap was a common problem on the 04 Aveo's; in fact the dealers were fixing them for free then. Tightenning the cap wont imediately turn of the light however because the computer needs to see the engine go through several drive cycle conditions before clearing.

Inpect the cap, the seal and the fuel neck. Perhaps cleaning the cap and seal area if necessary. Look for cracks in the fuel neck. If all looks good and this doesnt work try a new cap either aftermarket or from the dealer.

I filled my gas tank with regular gas and 5 mins later the check engine light came on and the low fuel light came on. I turned the car off and let it sit for an hour. I made sure the gas cap was on...


Im faily certain you have a problem with your fuel sending unit. Im not sure how common that is with Chevy Malibus but i replaced that in my 98 jeep cherokee and that did the trick.

I have a hard time starting my 04 Santa Fe after i fill up


it was running then you removed the gas cap to fill ( extremely dangerous practice with car running)
that indicates that there is a problem with the EVAP system.
run the fault codes ( what the dealers should have done first ) and check for the EVAP codes , purge vent or solenoid problems

1998 Honda Accord with a engine code(check eng.light) #1259. what do I need to do to fix it. thank you.


The manual for your Accord indicates the following:
This indicator comes on for a few seconds when you turn the ignition switch ON (II). If it comes on at any other time, it indicates one of the engine's emissions control systems may have a problem. Even though you may feel no difference in your vehicle's performance, it can reduce your fuel economy and cause your vehicle to put out excessive emissions. Continued operation may cause serious damage.
If you have recently refueled your vehicle, the cause of this indicator coming on could be a loose or missing fuel fill cap. Check the cap and tighten it until it clicks. Replace the fuel fill cap if it is missing. Tightening the cap will not make the indicator turn off immediately; it takes three driving trips.
If the indicator remains on past three driving trips, or the fuel cap was not loose or missing, have the vehicle checked by the dealer as soon as possible. Drive moderately until the dealer has inspected the problem. Avoid full-throttle acceleration and driving at high speed.
Hope this helps you find the problem.

Check engine light came on, along with low fuel indicator.


I took the vehicle to the Jeep dealership, and the problem went away before they could check it out. They are going to check wiriing next, because the check engine light went out on its own, and the fuel gage began working corectly on its own. Not sure what caused it, but hope to have an answer from the dealer.
