Every time it rains I hear what sounds like rain drops hitting the back side of my firewall. Only does it when I am moving when it is raining. Anyone else experience this or have any idea what it could be? Jeep isn’t leaking any where.

Someone else mentioned this also. They thought it was loud when rain hits the plastic panel near the wipers.

That could be where it is coming from just doesn’t make sense I only hear it when I am moving - maybe it is because it is hitting it harder I don’t know.

I drove it for the first time in the rain today and there is definitely a noise, could not identify where it was coming from, but it only happened at speed.

I’ve put plenty of miles while raining and there is no noise. So I say it’s not normal.

I hear the noise when it rains. I have a sport. Possibly different material piece for sports?

It is like a more intense rain sound when moving at speed (above 35), I do not think it is anything wrong, but it is definitely a different sound than rain hitting the Jeep standing still.

i just heard that last night while driving in the rain. At the stop light,no sound, started moving and begins to sound like rain hitting a "tin roof". It does seem to be coming from the area in front of the windshield. Very odd.

Interesting, I thought it had something to do with the Rubicon hood. Now I am really curious about what this is. How did Jeep not catch this during all the test driving they did?

Do you think rain is falling through the hood grill near the wipers and directly on the firewall while driving?

Could it just be the rain hitting the plastic hood grill near the wipers at greater force while driving vs at a stop?

I’m pretty sure it the acoustic windshield. Sounds like rain on a tin roof to me.
But I don't have the special windshield and I hear it as well.

I heard this for the first time today while driving. Whenever the car was moving, no matter the speed, the noise started. At a stand still it completely went away.

I am thinking it has something to do with the grill in front of the windshield - next time it rains I am going to cover the grill with a pieces of cardboard and go for a drive - hard to diagnose since it seems like we all only hear it when we are moving and it’s raining.

Drove yesterday in the rain and my wife says, "Why does it sound like rain hitting a tin roof in here?" Whomever said it earlier, was spot on. I guess it could be the plastic, def. the windshield area.
