I have a 2010 Ford Fusion I4 SEL with a healthy 82,000 miles on it (thanks to a decently long commute).
This past Friday, about 1 mile after pulling off the interstate (thankfully), I experienced substantial power loss, the wrench light came on, and the car was shuddering noticeably. I was able to pull off onto a local cul-de-sac, at which point I fully expected the car to die. I turned off the engine, waited about a minute, and though it took longer to start than usual, the car started up and ran normally (and the wrench light was off).
As soon as I got to work, I headed to this forum and lo and behold, found this thread. This was helpful because, when I called the dealer, I told my preferred service tech that I suspected it was the throttle body. He agreed that it "sounded" like a throttle body issue (he admitted this is a known issue). After driving home from work Friday night, I did not use the Fusion all weekend except to do a night drop at the dealer on Sunday.
Dealer called this morning - guess what? Bad throttle body. It is covered under the extended warranty (albeit with my deductible).
I've read here and elsewhere that people have experienced this multiple times and even some dealers have refused to repair because of "failure to replicate." That boggles my mind. I can't even imagine what would have happened if this had happened to me on the highway.
