2003 Mercury Mountaineer Owner Comments

problem #6

  • 105,000 miles


I purchased a 2003 Mercury Mountaineer on 2/15/14 and I took it on a road trip on 2/16/4 with my grandkids. After entering the highway and gaining speed I started to smell a strong burnt rubber and exhaust smell. The smell was very toxic and stuck to our clothing. On 2/18/14, I took it to the dealer for his mechanic to take a look at it. The mechanic said there was some degreaser that overflowed from a cupler and leaked onto the exhaust. I asked if there was a leak and the mechanic responded by saying not really, which meant there was a leak. The mechanic assured me that the problem was taken care of, but if it still occurs, they would send it in for two days. I continued to smell the toxic smell and on 2/19/14 the hatch on lift gate just cracked. Also when I turn at a low speed, I hear a strange sound and vibration, coming from the tire area. I've heard of numerous issues and complications with the Mercury Mountaineer. I don't want my grandchildren nor my life put in danger. A driver should be ensured with safety when driving a vehicle. Ford doesn't care about their consumers to sell defective and nonsafe vehicles. Please recall this vehicle as it has too many issues that can be life threatening, like the rollover rate.

We have experienced two well known issues with the Explorer/Mountaineer. The body panel on the back hatch is cracked in the middle and Friday we had the spark plug blow out of the head/socket stripping the threads out to the point that the common repair kit used for these instances won't work and the only solution is a replacement head which is quoted at a $3500 job and the vehicle is only worth about $5700. I understand Ford accepts no responsibility for this engine/head defect despite the fact that it has occurred on factory tightened plugs.

The contact owns a 2003 Mercury Mountaineer. The contact stated that the rear driver's side wheel bearing was replaced 3 times within 16 months. On October 1, 2008, while driving out of the driveway at an unknown speed, she heard a loud noise. The vehicle was towed to the repair shop and the mechanic stated that the rear driver's side wheel bearing failed. The contact stated that the vehicle was not driven on dirt roads, only in the city. She feels that either the wheel bearing is defective or the Ford dealer did not properly correct the previous failures. The Ford dealer stated that the vehicle is out of warranty and the wheel bearing is only good for 12,000 miles. The manufacturer took a report and stated that they will forward her information to the dealer. From there, the dealer will determine if the vehicle will be repaired. The failure mileage was 74,494 and current mileage was 104,000. Updated 11/14/08 the driver side visor was hanging down, the vehicle stalled on several occasions. The lower ball joints and outer tie rod ends were replaced. The rear hatch window cracked. The vehicle would crank, but it would not start. Updated 11/18/08.
