Annoying Squeak - goes away when warmed up

[bgeviljim]

Hi,

First post - shame it’s about a problem…

I’m in the UK and have taken delivery of my brand new GT Convertible (now with 500 miles).

At low speeds going over bumps there is an annoying squeak. It sounds like it is in the cabin to me - but a passenger says it sounds like it’s underneath the car.

Weirdly, the squeak goes away - in the main - after a couple of miles/when she’s warmed up… like a short trip out she’ll squeak. The trip back and the squeak goes away.

This lead me to believe that it must be something in the engine bay/underneath/suspension that is affected by warming up - if it was an interior or roof thing, it would be there all the time.

Squeak is there in the same place whether the roof is up or down.

Squeak is there in the same place whether the windows are up or down.

The squeak is there in different suspension modes.

The squeak is there with interior fans on or off.

I cannot get the squeak at a standstill by bouncing around inside the cabin or standing outside and bouncing the suspension. It only happens when I’m driving, seeming worse at low speeds (but that could be that the lower speed roads tend to be more bumpy).

Any ideas? Would appreciate the help!

Thanks

Can you catch a sample?

Exhaust hangers? Grab and shake exhaust (while cold of course).

Probably suspension related maybe ball joints. Take it to the dealer and get them to check everything out.

If you park in the garage park outside in the sun letting things warm well. Then take it for a drive to see if your problem is gone. This might show a windshield issue. Convertibles have some differences in that area. Just a thought.

Thanks all - I’ll try and record a sample tomorrow.

Will try and wiggle the exhaust too.

Don’t have a garage to park in - but it’s very warm in the U.K. right now and the car’s parked in the sun all day. Thanks for the tip though.

Really struggling to record the noise… I think CarPlay cancels video recording on iPhone… going to have to try with a spare phone that’s not connected to the car.

I did try and wiggle the exhaust, but couldn’t raise a squeak.

The hunt continues…

I had that in a Toyota 86. Finally found a piece of plastic sheet under the infotainment system that rubbed on something until it warmed up and lost tension.
Took a couple of years to find that PIA. That left a million other noises to find.

So I was able to self-diagnose the problem, Jerry rig a fix to prove myself correct and then get the dealer to complete a proper repair…

Sharing here for anyone else who might suffer the same thing…

The strut brace was touching this piece, so every time I went over a bump they rubbed together, with the strut brace acting as a tuning fork and making a loud squeak.

I added some silicone lube and wedged a thin shim of plastic between the two and boom - no squeak for a week.

Dealership unbolted and moved the strut brace to give it a 2-3mm gap and now we’re problem free.
At least with this issue!

It could be a mouse. Keep an ear to it.......

Great diagnosis.
