Im driving a 2004 Sonata (gold)
After 1 year of comfort driving the 4 cylinder , 16 valve enging
starts to give a funny sound.

The engine gives out a "howling" sound.
It happens only after the car is parked for about 2 to 3 hours
and when you start the engine and drove with a speed of about 25 kph
with 1st and 2nd gear.

Kindly advise
Thanks

 

Listen for the noise from the timing belt area. Those vehicles were bad about the timing belts coming apart.

 

If your noise is only occurring when you are on the move, it could be a worn brake pad, as these have sensors in them which give off a high pitched squeel, instead of having a warning light on the dash.

 

i've had the same issues with my 95 sonata it is the belt tentioning arm that needs replacing good luck
