Traveling down the interstate, left lane @ 70 MPH. I had 1 vehicle behind me and a semi truck / trailer to the right and one behind him. Without warning the engine died and I began coasting in traffic. I hit my flashers and thankfully the vehicle behind me was alert and noticed my instant loss of speed and flashers. They slowed long enough for both big trucks to pass on my right and for me to get over to the shoulder on I-70. Quick research turns up possible issues with a mechanical / electrical pump or maybe the throttle body. I called the ford dealership and talked to the service manager who didn't have a clue what would cause the issue and was surprised that I found several postings on the internet where people had the same issue in the same model vehicle. I visited the ford dealership and spoke with the parts department (2 individuals) who couldn't decide which was the correct part number for the mechanical / electrical pump. It is just a matter of time before someone experiences this issue and can't get out of traffic and is involved in a serious or fatal accident as a result. It is a known issue and I also noticed there is a class action lawsuit filing because so many have experienced this same issue. I'd be interested to know what criteria needs to be met before the federal safety agency takes action against ford / mercury.

I was traveling west at about 70 MPH in the left lane on I-66 out of washington, dc with four people in the car. Suddenly, the engine died and we were left with only the electric motor on the hybrid and a dash warning of a red triangle and the statement "stop safely soon." the car quickly lost power to about 30 MPH and we struggled to get across the four lanes to the shoulder. The electronics in the car still operated (radio, dash lights, etc.), but the gas engine stalled. Once on the shoulder, we stopped. The ford owner's manual told us to turn the car off and try to re-start. We did this and the car re-started. We started to drive, but the car did the same thing after about 5 minutes. The car did the same thing on about 5 different occasions until we could get to an exit that had businesses. The ford dealer in this area (away from my home) states that the electronic cooling pump needs to be replaced. Although I understand that parts fail, my complaint is that ford should not tell owners to re-start the car and try to proceed on. It is dangerous when it continues to fail and you don't know where the next failure might occur (on a bridge, in a construction zone, on a busy, fast interstate). Moreover, having reviewed complaints on this site and elsewhere on the internet about ford hybrids, I know that many others have experience this situation where the car engine stalls at highway speeds due to various problems (e.g., the electronic cooling pump, bad sensors, or a corrupted PCM).

Car is still sitting in dealership waiting for my decision to repair or not. Car was not abused. Mostly only one passenger. Car was serviced regularly as per specs at dealership.
