 I backed suv out of garage and put in park, got out of vehicle while still running (to close garage door), closed the suv door, turned around and saw that suv was moving forward into my garage. i opened the suv door while it was moving and jumped in the drivers seat, pushed on the brake and suv did not stop, i was looking down at the floor to see why suv did not stop, pulled up my foot and placed it back down on the brake. suv still did not stop. it then made a loud noise like the engine was reeving up and then the suv took off forward, ran through the back of my garage, ran through my back yard, ran over a tree in the yard, ran through my back yard fence and my neighbor's fence and crashed into the back side of neighbor's house. all while this was occurring, i was inside of the vehicle with my left leg sticking out of the car (since i jumped in the suv in a hurry, i didn't realize that my leg was still out of the suv), i continually attempted to step on the brakes (each time lifting my foot up so that i could place it directly on the brake), the engine reeved up again while going through the yard. the only thing that stopped the suv was the tall concrete foundation of my neighbor's house that it ran into. i jumped out of the suv, fell to the ground and laid there for a few seconds before i realized that my suv was still running, then i jumped back into the suv and turned the ignition off.

11/12/200910500
 I own a 2004 ford explorer that has experienced two overheating incidents, the second resulted in replacing the engine. the first incident was caused by a stuck thermostat and the second by a leaking hose between the thermostat housing and the engine. in both incidents when the engine temperature warning activated, the temperature was buried in the hot end of the gauge. in both incidents, i immediately decelerated and pulled off the road but in the second incident, the engine was already ruined. an article in the april 2010 issue of design news (made by monkeys, pg 10) about a similar incident with a mazda led me to believe mine was not an isolated occurrence but a result of increased use of aluminum and better cooling systems. in the mazda incident, the engine had been replaced once and was saved from a second replacement only because the driver was looking at the gauge when it suddenly pegged into the hot end. the problem is there in no warning of low coolant until the level drops below the water pump which results in a sudden and often catastrophic rise in engine temperature. the explorer is the most heavily instrumented automobile i have ever owned yet the cooling system warning is stuck in 60s when cars had cast iron blocks, overheated gradually and were forgiving of overtemps.

 I bought a 2004 ford explorer xlt at darcars toyota in silver spring md. it had only 28,000 miles. the plastic valve cover was found to have a crack where one pours the oil in. there was an oil leak around this area. apple ford in columbia, md. said this would not be covered by ford warranty. i thought ford's warranty covers to 3 years or 36,000 miles. this valve cover was over $400.00. why shouldn't this be covered. i signed a paper that states that the ford warranty should still be in effect to 36,000 miles. i don't know how or when this crack occurred, but i have only had the vehicle for 3 weeks. i think this should be covered by ford warranty. *jb

 We have a 2004 ford explorer eddie bauer, originally purchased in may 20'06 with approximately 30,000 miles . at approximately 36,000 miles in august 2006 we were told that the harmonic balancer needed to be replaced. that was about $500. my husband drove it to work on 3-19-07 and everything was fine. he took it to lunch, everything was still fine, and when he came out, he tried to start the vehiclem and it would not start. there were no check engine lights, no noises, nothing out-of-the-ordinary at all. we had it towed to a ford dealership, who ran some tests, and initially could not figure it out. they ran more tests, and came to the conclusion that the cams are not working. they told us that the engine needs to be replaced. $5,600.00 to replace the engine with 46,000 miles. ford is not offering us any help. they refuse to stand behind their product. they said if we had the extended warranty it would be covered. but the point is that it has 46,000 miles. i need someone to help me before i explode! *ak
