CarComplaints.com Notes: The 2004 Ford Explorer one of our worst vehicles on record. "Avoid like the plague" is putting it lightly.

The 2002-2005 Explorer has a very well-established record of expensive transmission failure at under 100k miles. The Explorer has an enclosed transmission which is typically replaced with a rebuilt transmission at a cost of almost $3,000.

Another common problem for the 2002-2005 Explorer is wheel bearing failure at around 90k miles, with a typical repair bill of $500 to $1000 depending on how many wheel bearings failed.

Adding insult to injury, the 2002-2005 Explorer also has a massive problem with the rear panel cracking. While it's a minor annoyance compared to transmission failure, ironically the crack usually goes right through the Ford logo.
