2006 sonata problems

Anyone experience noise from rear of car when fuel tank is full? Told by
Hyundai that it is a "normal" noise.

 

Can you describe the noise and when it happens? I've heard no complaints.

 

None on ours ..... only have ~1,100 miles on the clock though. What kind of
noise?

I have about 1400 miles on mine and have not heard this noise yet either.
Are you talking about a sloshing sound?

 

The sound seems to be more of a rolling noise. Again only when tank is
above 5/8 full.

 

When does this rolling noise occur? Is the car running? Is the car
moving?

Can you be more descriptive than rolling? I know it's sometimes difficult
to describe noises, but we really can't offer much unless we have a good
idea about what the noise sounds like and when it occurs. Try to use an
onomatopoeia to describe your noise if you can. Maybe even make up a word
that phonetically would sound like the noise.

 

Noise is primarily at low speed and changing speeds.Originally thought it
was suspension-rear wheels-now believe it is fuel rolling/sloshing in
tank. Whooshing then banging is best description I can come up with.
Anyone else have this?

 

I've had that in every car I've ever owned. Some you can hear better than
others. I really don't think it is an issue to worry about.

 

I have 800 miles on mine...NO noise.

 

Whoosh-bang sounds a little disturbing if it is very evident. I worked on
an Elantra that had a baffle come loose inside the fuel tank.

But I'm in no position do doubt someone who actually heard the noise and
checked into it, either.

If you're concerned about the noise, the dealer should be able to explain
to you the cause or, if they don't know the cause, should be able to
demonstrate the noise on another identical vehicle to appease you that it
is a normal condition.

 

I think I've experienced this. I rented an 05 Sonata recently and after it
was down below 7/8 or so, I sometimes encountered a sound that had me
believing something heavy was rolling around in the trunk and slamming
about. The trunk was completely empty. The couple times that it happened
to me were both times when I was stopping, or slowing significantly to make
a right hand turn. It was indeed a very noticeable rolling, then clunk
sound.

 

The noise is the result of no Baffle in the gas tank. Hyundai is aware of
it and is supposedly trying to come up with a fix for it.
