Hi. First I promise that I have searched everything related to all ticking, cracking, rattling noises in this and other forums already. I searched and did a lot of DIY until my wife calls me crazy.
I have been having this ticking noise coming from the back of the car. Happens over slightly rough road that makes the car vibrates. It's almost like a metal to metal and it's not very lough (yet enough to hear)....tick tick tick tick. Pattern of the sound is not of regular interval. So I guess perhaps may be it's not the fuel pump checking the pressure as a lot of us here are hearing.
Not sure if it's the seat or other parts though. So far, I have done the following in the attempt to silence it.
1. Door rattles: Installed anti-friction tape to the car's body along the door where it meets the felt seal. It silenced the creaking from the door 99.5%.
2. Secured spare tire by tightened it.
3. Lithium greased at all of the door latches (4-doors).
4. Wrapped the D-Ring that the back-seat latches snaps onto it with cloth tapes.
5. There is a plastic ring at the gas cap - the one that has the rubber wire connecting the car body. Tap it slightly and it rattles. Silence it by using cloth tape.
6. Inspection by lifting up the car and inspect the underside. Everything is secured. At first find, there is some loose nuts securing the heat shield so I got the dealer to tighten it. All other parts are secured and make no noise.
7. Tapping lightly all over the car when parked. No sound whatsoever.
I took the car to the dealer and they initially heard it too. Told me to bring the car in again in a couple of days cuz it was already 4pm and i didn't want to leave the car there over night without them doing anything on it.
Next day, the sound was gone. And it was gone for a week. THen back again. So i ended up haven't delivered it to the dealer yet. Had a feeling that they will end up saying "we couldn't hear anything" and that will be a waste of time.
Fast forwards 3 weeks and 3 tanks of petrol. Now I begin to notice some pattern:
The sound only comes when the tank is fully filled up.
The sound will occur only when on slightly rough road - those that makes your car vibrates (not those big holes).
The sound does not occur when idle.
The sound will go away by itself after I spent around 1/4 of the petrol (leaving the car 3/4 full).
And it's back again as soon as I fill it up to full tank.
If anyone have any idea what it is, please please please help for initial thought. I just don't want to go to the dealer with blank head and tell them "there is a tick sound. don't know what it is and where it come from" and then let them tear apart my car.
If it has been already discussed somewhere and i missed it, please point me into the right direction.
Many thanks.
