Notes: The previous generation of Explorer was so awful that the redesign in 2006 was greeted with much optimism. That didn't last long.

The transmission continues to be the Explorer's worst reliability problem. Owners report shifting hard & lunging, typically starting as low as 40k miles with a $1,600 average repair bill. On top of that, the radiator is prone to failure around 60k miles. Repairs for the radiator run $500 to $1,000 & many owners report they've had to replace the radiator multiple times for leaks, indicating a possible design defect in the OEM replacement parts.

Ford did make some significant changes to improve handling and safety. Electronic stability control was added in addition to side impact air bags, but beyond that this is a vehicle that should be avoided at all costs.

Explorer 6-cyl

I have had the door blender plastic piece changed on my car three times! each time the season changes. I now have to replace it again. I currently have a radiator leak and will have to replace the radiator and plastic holder as well. I also currently have a transmission slippage problem and I will have to get that fixed as well. This is horrible. I purchased the Ford Explorer because I thought it was dependable. This is depressing and I can not afford it!

While trying to turn on the air conditioning, a clicking can be heard and the air flow does not change over. Then during cooler days the heat is inoperative, (it stays on cold air) the clicking is persistent.
