Driving on highway at 63 mph and valve spring broke. Valve dropped into piston causing engine failure. Check engine code called for random engine misfire and code was triggered at around 2600 RPM. Prior to engine failure I have been experiencing a shudder when transmission shifts into overdrive. There is also a problem with the clutch pack in the limited slip differential that is causing a shudder when turning right or left from a dead stop. (dealership called it the parking lot shudder) I have a 02 Ford Explorer XLT with 4.6 and 4X4 that has bad engine, transmission, and rear differential. (engine replaced).

In January, 2006, my car stopped dead on the highway. After it was towed to the dealership, we were told that a valve had broken and had been sucked into the engine, causing engine failure. Our only alternative was to have the engine replaced - which we did for over $5000. The following January, (2007), after the first measurable snow fall of the year (since our engine had been replaced), the car went into a huge fishtail skid on a snowy road and after the first skid, was caught by the cable guard rail on the side of the road - causing another $5000+ repair. When brought to the dealership after the accident, we were told that the 4 wheel drive electronic monitor had failed and we had no 4 wheel drive. My concern - besides the cost and inconvenience and scare of the accident is that there were no warning lights to let me know that the car's 4 wheel drive had failed. I had gotten into the car assuming that the 4 wheel drive was working (as the car goes into 4 wheel drive automatically and there are no indicator lights normally to let you know that the 4 wheel drive is working). With no indicator lights that the 4 wheel drive is working and no indicator lights that it is not working, Ford put me in a very unsafe situation. Had the cable guard rail not been there to catch the car, we would have gone over the embankment and been more seriously injured.

I have a 2002 Ford Explorer with 60K miles on it. It recently blew a spark plug out of the cylinder head while on the highway resulting in loss of power and alarming noise. The failure occurred on the chesapeake bay bridge and could have resulted in an accident. This is a common problem that does affect safety of the vehicle with Ford V-8 and V-10 engines that has not been properly addressed by Ford. Estimates to repair this defect in the cylinder head threads range from 2500 to 3500.

This vehicle has not been involved in an accident yet but I have told the Ford co. That it is dangerous and they ignore me. When you come to a stop at a stop sign and start to pull out the vehicle will roll into moving traffic and hesitate 4-5 seconds before the gas finally catches and the vehicle goes on. Mean while you have traffic bearing down on you. We have come close to getting hit several times because of this problem. I think this needs to be investigated as a potential problem for other consumers besides myself.
