My ST has developed a substantial rattle at speeds under 25 mph on bumpy surfaces. I sounds kind of like the hatch isn’t latched, the parcial shelf is loose or the seat back is not latched. Everything seems ok when I tug on it so I am a bit perplexed. I plan on running with the shelf out then the load floor out then the seats folded down, etc. in an attempt to locate the cause. So far I’ve proven it’s not the seat belts by latching them and that it’s not the spare tire or the jack that’s the issue. Has anyone else seen this issue before? FYI my orginal parcial shelf cracked somehow and was replaced but I didn’t carefully check to see if they were identical before I tossed out the old one.

I'm guessing that it may be the muffler. The exhaust hangers are real soft and the pipe moves quite a bit on bumpy roads. Cobb just came out with a set of hangers that are probably much stiffer than stock.

There are a couple adjustable rubber bumpers on the corners of the hatch, try screwing them out a little at a time to see if that stops the rattle.

Had a horrible rattle last year in my SVT and that's all it took to clear it up.

If it sounds like a high pitched squeak it is one of the rear interior panels that poped out. Happens to me when I do dirt courses. You just have to give it a wack with your hand and they pop right back in.

Hi AlanBDahl,

I want to check into some options. Please send me a private message with your VIN, mileage, best daytime phone number, full name, and dealer name/location.

Might want to give your rear springs a eyeball too maybe the foamrubber has worn threw and you have the rear spring chirp I find most plesant as I know the car is getting used properly then

After much fiddling I've determined that it's caused by the left rear headrest's mechanism inside the seat being loose. I'm not sure what that is going to take to fix.

Glad to hear you found it.

Update: It appears that the lower outer pivot point bracket for the rear seat on the driver's side is loose too and may be the major issue. I've also had issues with the seat back not latching which may or may not be related. Since I've found loose bolts in that area related to the plastic bracket for the 2-height cargo floor I'm beginning to wonder if a worker didn't space out and forget to tighten a bunch of bolts?

Anything can happen, could be human error and even a machine can fail. Might be worth getting it noted in the cars warranty history just on the off chance that it's not just yours. Could help with diagnosis of other vehicles.

I had a rattle with the rear seat latches and put electrical tape around the loop steel piece and the rattle sound went away.

I might have the same thing but mine is more of a thunking then a rattle. It sounds like something is moving around in the trunk. I'll be checking those bolts tomorrow.

Hi 70sstrat08,

If you plan on heading into a dealer for this, please let me know. I can look into this further.

It turned out that both rear seat striker plates were misaligned. The dealer adjusted the strikers and added "anti-rattle tape" and the noise is now gone.

Glad you were able to get it figured out. I have a feeling I have the same thing since one of the seat backs seems to be the only thing loose back there.

I'll be taking it in for this and my window rattle issue.

Hey LuvfiestaST,

Have you consulted your dealer about this rattling sound? Send over your Fiesta's year and current odometer reading; I'll look further into this.

I'm about to sell this thing because of the rattles!! This car has more rattles from the rear hatch and steering column area than any car I have ever known. I have torn it down to bare metal in the truck area and hatch lid to no avail. It's headed into the dealer on Thursday. Very frustrated because I live this car.
