Tl-the contact owns a 2007 Mercury Mariner Hybrid. The contact stated that while driving approximately 65 mph, the vehicle stalled as the check four by four, service brakes, and pull over safely warning light illuminated. The vehicle was not diagnosed or repaired. The contact mentioned that when the brakes was depressed, the vehicle jerked forward as the traction control warning light illuminated. The vehicle was taken to an independent mechanic but the failure was unable to be diagnosed. The manufacturer was not notified of the failure. The failure mileage was 65,000. Ss.
I was driving my '07 Mariner Hybrid on the NJ turnpike at freeway speeds when the red triangle & message "stop safely now" appeared on the dash. The propulsion system stopped and I was able to navigate off to the shoulder and bring the vehicle to a safe stop. Having an immediate loss of power while traveling on the turnpike was very scary and I felt unsafe knowing that I didn't have any options but to exit the freeway immediately. This could have resulted in an accident. After letting the system sit for about 20-minutes I started the vehicle and resumed my travel. Same error message and loss of propulsion happened again, and this time I navigated the hybrid to a Ford dealer in NJ. It's very scary to be traveling at highway speeds and then a second later not have any propulsion. This could be handled much better and I recommend the engine continue to perform so that I can safely exit the freeway with more time.
Travelling on illinois I-55 south early in the morning. About 2 miles north of us highway 6 exit car lost power and I noticed "stop safely now" message. I pulled off to side of road. Car started right up. I went about a 2 miles and car did the exact same thing. I was real close to the golf course and made it there. No problems on the way home or since. Car never acted or sounded ?funny?. Car repaired by local Lincoln Ford dealer. They said they replaced an engine coolant pump ($695 including labor and taxes) that is unique to hybrid. They said I was the third hybrid this week-end--probably had something to do with cold weather. Coolant pump has a different design so they may have had original design problems.
