NHTSA Complaint #11592963 — 2007 FORD EXPLORER

My check engine light came on and the car was making a loud acceleration noise when touching the gas. I took it to the dealer and they found that the wiring harness (Part# 7L2Z-12A581-CB) was faulty and needed to be replaced. The dealership told me they are trying to locate the part. This went on for 8 or 9 months when they informed me that the part was on a national backorder. No one had this part in the US or Canada. I also contacted suppliers and dealerships myself to help find the part. On multiple occasions I spoke with my Ford dealer, Ford Parts Department and Customer Resolution Center. They keep telling me that we have to just wait for the part. I explained that it's been 9 months and asked if they can tell me how long it will take. They said they have no ETA. I explained that my car needs to be inspected by the end of the month and it won't pass without this wiring harness because my check engine light is on. I can't get an answer as to whether or not the part is on backorder or discontinued, and if backordered, when the part will be available. In the meantime, besides the fact that my car won't pass inspection in a few weeks, I'm also concerned about my safety driving with this faulty part. Multiple things can happen as a result including the car catching on fire. I need the part to fix my car and pass my inspection. However, I'm being told it's not available and there are a lot of units ordered and waiting. Is it possible that many others are experiencing the same? And if so, is this a faulty part that should be recalled? Thank you.
