So this will most likely be the last thread I start regarding my Fiesta ST. It was a fun little car, and the spirit of it is fantastic, but Fords quality issues and warranty antics soured me. The last straw was water leaking into the boot. Specifically the spare tire well.
We have been having a biblical winter here in Norcal, and after the first big rain I noticed my car was musty inside. I checked the carpets and everything was fine. Well then the next storm hit, and the next, and the interior started to stink. So I popped the hatch, pulled the cargo floor and sure enough the spare tire well had water in it. I dried it all out, mopped it up then set about trying to find where it was coming in. After searching the forums, there were a few hits that pointed to either the tail lights, the hatch hinges or the wing bolts being the culprit. So I sealed around the hinges, checked the taillights (really no way for water to get in here) and waited for the next storm.
Next storm came and same problem, 50 miles on driving on wet roads and 1/2" of water in the spare tire well. So then I pulled the side panels out and started trying to find the source. It appeared water was leaking in from both sides, when I got a flash light in there I found out why....So Ford decided to put the "airbrake vents" that allow you to close the door or hatch in the top of the rear wheel well. Then decided a fabric/carpet/paper wheel well liner that stopped short of the car body was going to keep water from intruding in. Sure enough, both sides, and water trails from those vents. I am out of warranty, and seeing that this was indeed a design flaw and sealing those vents with some sort of silicone would likely be a temporary fix, I cleaned it up, dried it off, and traded it in. So check your spare tire wells after driving in the rain, hopefully it is only a 2014 problem.
