Hood moves up and down while driving?
 
Hi, I have a 2013 wrangler Sahara and I noticed when I go 70+ and its a little windy out I can see my hood move up a little when the wind blows hard. Is this normal?

Raiderfan001 02-24-2013 05:49 AM

Yup. Known as hood flutter. There are some fixes for it both home brew and aftermarket like better hood latches.

mckey73 02-24-2013 05:54 AM

Yeah, it's pretty normal. There are a few solutions but I removed the spring on the hood and haven't seen any significant movement since. Last week I was driving into a 40 mph headwind @ 80 mph and there was some movement when I passed big trucks, but nothing to worry about. Some people have upgraded their hood latches, there are many choices.

Do a search for "Hood Flutter".

Thanks.

One would think Jeep would have fixed this issue by 2013... That actually upsets me.

There is a slight amount of adjustment in the hood latch. The bottom mount can shift downward and increase tension. May not eliminate flutter, but it will help.

I'm having trouble looking for this adjustment, can you show me a picture?

Sorry, I meant top(hood). Not enough coffee yet to think strait. The two mounting holes are slotted in mine. I moved the mount as far up as it would go and no more flutter

I'm going to go try that, give me 5 minutes.

Still not sure what you're talking about.

Loosen these and move assembly up as far as possible. This will increase tension on the rubber when you latch the hood

So sorry that this upsets you, but it isn't really an issue. Your hood will not fly up. Either remove the spring, or replace the latches. There are only a couple hundred threads detailing this.

I use these aftermarket latches...

Rampage Products 76336 - Rampage Products Locking Hood Catch Set in Black for 07-13 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec

Of course I sometimes park my Jeep overnight in Chicago, so they give me a little extra peace of mind.

One of the first things I added to our 2013 Sahara when we brought it home was a pair of Rampage locking hood latches. I didn't buy them for the hood flutter issue I'd read about but for the security. I couldn't believe that anyone could just walk up to it and raise the hood.

I know it won't stop a determined thief but it'll discourage any theft or vandalism, more so than not having anything at all. They apparently also have stopped any hood flutter.

I travel to and from work 30+ miles every day on the interstate at 70 - 75 mph and have never noticed this. Is this present in most Jeeps or just a few?

I have an 08 with flutter and a13 without. So from my perspective 50% if jeeps. LOL

Only happens in the 08 with heavy wind gusts head on

joeymon1 02-24-2013 11:59 AM

It seems that I need a pretty strong cross wind to cause it.

I never noticed when my JK was in stock form, after lifting it got bad since I am now sitting much more nose high.

termite 02-24-2013 12:21 PM

Mine did not do this until I removed the air dam. I'm planning picking up the rugged ridge aluminum hood latch in the near future.

Raiderfan001 02-24-2013 12:24 PM

If you're on a small highway like one lane each direction and pass an oncoming semi you'll see it happen.

Simple fix :)

Texas_Jeep 02-24-2013 01:15 PM

spend $25 and buy these Daystar KJ09145BK - Daystar Hood Wranglers for 07-13 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec Easy install and will take less than 30 min.

It depends. My 10 has never done it. I've read the above about an adjustment. It probably depends upon how the install was at the factory. If mine starts to do it I'll go aftermarket, but for now there's no problem.

Mine supposedly does it. I can't see it, but my passengers always seem to notice it. It freaks 'em out.

JKRONNIE 02-24-2013 07:24 PM

I second the Rampage! Snugs the hood up real nice, extra security is a bonus.

mariner09 02-24-2013 07:32 PM

I just put the DayStar latches on my 09 last week and haven't seen it since. I had it bad for the last 3 years and finally did something about it...

P51mustang 02-24-2013 07:40 PM

+1 for the daystar hood wranglers. Fixed my issue, I wish jeep would keep the latches and put a normal hood latch mechanism to prevent theft.

genesbro 02-24-2013 07:47 PM

I bought the Daystar latches for my 09 right after the first time I met a semi headon with the usuall wind blowing hard and I know it won't come up due to the safety latch but it sure looked like it wanted to take off. After installing the Daystars' it doesn't move at all. Very simple you just replace the rubber factory things with the stronger material from Daystar and that is it, done.

Flaw to failure. I noted the the "flutter" in my 2013 Sahara Unlimited soon after purchase, but discounted as a harmless quirk. Yesterday changed that. Driving in Montana on a two lane at about 65mph, a large semi passed me going the opposite direction. Large wind blast and then my hood flutter was much increased. Pulled over to inspect and the outside latch on the passenger side had simply fractured in two. Resumed driving, but now all the flutter force was being transmitted to the driver's side outside latch even at speeds of around 50 mph. It seemed likely that another large wind blast could break the remaining outer latch, but some twisting of the hood would be probable in the process given no passenger side latch. So would that torque/twisting then be enough to disengage the inside latch and pop the hood open? Did not seem too improbable. Will definitely be buying one of the alternate latches mentioned here to replace the plastic ones that came with the vehicle. However it seems like there is potential for this design flaw to become a serious risk under typical highway speeds.

Wranglers have always had a similar hood design latch. Don't really hear of problems. Before you spend the money, pull the hood spring.
