Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2003 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 2002-2003 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.


definitely annoying

Explorer 4WD 8-cyl

  • Automatic transmission
  • 35,000 miles


Dear NHTSA: In October 2003 I purchased the nbx - V8 version of the Ford Explorer with an upgraded tow package for my wife. She never uses the tow package and I, very occasionally pull a 300lb utility trailer. I get the oil changed religiously and recently had the 30,000 mile 4WD lubrication package from Goodyear for approx. $500. At 34,000mi my wife began to notice a non-descript noise in the rear end, a rumble at slow speeds while turning. She carries things in the back and thought they were rolling around. I drove the car at 36,600 mi and also noticed the noise but we had a low rear tire and I thought it was the tire pressure. The tire actually picked up a nail and went flat and I brought the tire to Goodyear for repair. After the repair the rear end noise persisted only at low speeds and we finally got the car in to Goodyear for evaluation at 38,000 miles. They replaced the rear differential fluid again and the noise persisted. They then went on line and pulled a technical service bulletin tsb 04-17-5 which was for limited slip axle chatter, shudder, binding sensation or vibration during low speed turning maneuvers in 2002-2004 Ford Explorer, 2003-2004 Expedition and 2004 F-150S. This was exactly what I was experiencing. Since this vehicle is not used off road, is not used to tow anything heavy, is pampered but does get a fair amount of highway miles 38,000mi in 19 months, I felt that having a transmission problem at this stage was unusual. Well, after talking to my manager at work, half the Ford Explorer fleet in boston was having this problem, with one vehicle in the shop 3 months and one never seeing the light of day yet. The tsb noted problems with the entire transmission. What about next time"? my vehicle. Vehicle # [xxx] Ford Explorer silver V8 nbx version? they also know they have a real problem with their transmissions and the consumer will end up eating it.

Explorer 4WD 8-cyl

  • Automatic transmission
  • 9,500 miles
I purchased a new 2003 Explorer XLT in mid-February 2003. At about 9500 miles the SUV developed a whining noise from the rear differential. Local Ford dealer confirms noise, but is unable to fix as "Ford engineers have not yet found a fix" also at 3800 miles the at failed and was repaired-not replaced. Local dealer is supposed to let me know. As of 3/9/04 no word. This SUV is a poor vehicle.
