Default Loud banging under car when hard rain...

2013 5.0 6-speed Manual
All stock except for cat back
9,200 miles

This morning was the 2nd really hard rain I have driven in where there was standing water on the road. I get this really loud banging noise after having to drive through a few of the water puddles. It is very hard to pin point because these cars are very loud inside when raining hard.

It seems to do it when I accelerate and it almost feels like the car is not accelerating as it should when it happens. Also, when I pulled into my parking spot this morning (hard left with clutch pushed in) it did it.

It only does this when it is raining hard enough for water to collect on the roadways. Therefore it is very hard to reproduce it.

Anybody got any ideas?

How weird. That's going to be difficult to guess without actually hearing it unfortunately.

Advance trac may be kicking in. Its hard to tell without actually hearing the noise. If its still raining on the way home turn advance trac off and see if you can reproduce it. Ive noticed it will make kinda of a clunking sound when it kicks in sometimes.

Mmm maybe ... which would make sense if you hit a puddle that is enough to cause some slight hydroplaning.

It has only happened twice now. Althought the first time it did it , it lasted for the last 2 miles home. I honestly thought my exhaust had dropped down and was dragging across the road. Got home looked under the car and everything was fine. Went in changed and took it for a test drive and couldn't make it do it.

If its making the noise for that long its not advace trac. Its weird it only does it randomly in the rain. If it was consistent when it gets wet that would atleast make it alittle easier to pinpoint.

That would explain why I've never heard it because I don't drive my car in the rain. lol.

Daily drove my C5 for 5 years. Seen rain, hail, ice etc. Not to detract from the thread. Hope all goes well for the OP.

Agreeded. As traction control kicks in on my car it makes a noise and bogs hard. Not so sure about the "loud" bang noise.

This has no bog with it like you get with the traction control. The banging sounds like it is coming from transmission forward and on the right side. (But again very hard to pinpoint). Sounds/feels like a monkey hitting the underside of car with hammer.

The first time it happened 3 things ran through my mind:

1)exhaust came loose and was dragging ( obviously it wasn't when I checked)
2)Extreme exhaust leak ( I checked all exhaust clamps when on lift and all were tight)
3) really really really bad clutch chatter ( doesn't make sense when turning left into parking spot when clutch is pushed in and on the brakes though).

That would be my guess

I tell you what, I'll ask some of the other techs in the shop and shop foreman if they've ever come across a customer complaint like this, and will check TSBs and SSMs on the car and will get back to you.
