NHTSA Complaint #11440300 — 2017 FORD EXPEDITION

My Expedition was set to 45 mph via cruise control in a work zone, at night, on the Chesapeake Bay Bridge Tunnel. While in the first tunnel in the northbound lane with 2 way traffic, I heard a slight pop, then rough running feeling and completely lost acceleration. The power train wrench warning light came on. Since I was on an incline in the tunnel with no way to pull over and the vehicle was going forward at a snail's pace, I decided to continue as far as I could since it was the safest thing to do for all drivers in the tunnel. The Expedition finally crept out of the tunnel and I was able to pull off to the side to let traffic pass. As soon as we had cell phone service, I had my daughter call the Chesapeake Bay Bridge Tunnel to let them know that we were disabled and in need of assistance. I decided to see what would happen if I turned the vehicle off and restarted. Everything reset and I had power, but for how long? The CBBT police agreed that the safest course of action for all vehicles on the road was to tow my vehicle to the other side as it is dangerous to breakdown on the CBBT, especially in one of the tunnels. I was able to drive home after the tow. However, the following day, I tried to drive it again and it did the same: ran rough, wrench sign, no pop that time, total loss of acceleration. Restarted and made it back home. My husband tested it a few days later after re-cleaning battery cable terminals that had been corroded before we replaced the factory battery, and it did the same thing with him on the highway! If we had been trying to get into traffic, turn where we had to cross traffic or any number of other situations and the Expedition lost power like that, the outcome could be deadly. The CBBT would have records since they towed me and wrote the VIN down.
