It continues to do the same thing.even when not driving it.”
NHTSA complaint #11155676, filed 2018-12, 258,603 miles“After having a new water coolant pump (the fourth one in my Mariner Hybrid) and a new throttle body being put into my car by a ford dealership, my car is still having the same problems. Now a service emission sys warning has come on, and being under 150,000 miles still I contacted ford to see what could be done since it was fixed by them but still has a problem related to the electrical hybrid powertrain, and ford says there is nothing else that can be done, even though it clearly is under the warranty that they created due to the failures of both parts.”

Traveling approx 65mph on the 5 freeway south in sunland, he heard the rod go and saw the lights on the dash indicate the engine overheating. He pulled off the 5 freeway and parked wear it was safe and called for help. I had aaa pickup the vehicle and bring it to the mechanic in westlake village ca.

I was able to get my car started after about 30-45 seconds. I started driving again, but it shut down again a couple minutes later. It has been occurring intermittently since that day, with today being the most recent. I called ford motors today and was informed that my car is on the recall list. They never sent a letter to me.
