Hey all, my wife has an 05 elantra and the idle has always been kinda shaky since practically day one of ownership. I have finally reached the point where something has to be done by the dealer.

Here is the scoop: Whenever we come to a stop, about 15 seconds after, the idle or something shakes a bit., kind of like when the radiator fan kicks in--- a rough type of vibration.

Driveability while the car is going is ok, but has a slight "hesitation" not exactly a hesitation but just does'nt move smoothly.

I am also noticing that the brake pedal seems to be going down a little further than usual, not sure if this is anyway related knowing the fact that this " roughness" occurs shortly after braking.

My biggest concern is when I do take it to the dealer(still under warranty) they of course will say " no check engine light----no code ----no can fix!"

How will I go about properly handling the situation?

Thanks for your time, and all the info you have already provided especially when I posted about the control arms rust/bust on my 02 elantra.

The two might be related if there is a vacuum leak in the power brake booster.

 

Thanks NovaResource,

Can I test if there is a vacuum leak by spraying starter fluid on that hose?

Also, any suggestions on how to deal with the dealer service department when they say " sorry no check engine light."

Can a small leak go undetected by the computer?
