Mercury Mariner Problems

If the transmission oil leaks out of left side half shaft area, it may be from a worn axle shaft seal. The seal can be damaged by a poor surface finish on the axle shaft. The axle shaft and seal should be replaced to correct the problem.

Looseness in the steering shaft and steering shaft coupling U-joint can cause a knocking / popping noise from the steering column when turning. The steering shaft and coupling U-joint will need to be replaced.

The transmission oil cooler may develop a leak, which will require replacement to repair.

Mercury Mariner Reviews

Bought my 2007 Mercury Mariner LX V6 4WD, used in 2009, with 24,000 miles. For the first year, I believed I had made a good purchase, however having to replace brakes (pads and rotors turned) at 30,000 miles. I didn't give this a second thought as the brakes may have never before been serviced. Then at 37,000 miles I had to replace them again. At 44,000 I had to replace the rotors, as well....

Has been a great car. Drive it every day for work. Done regular maintenance and have had no problems.

I bought this car and have loved every min of it. But, when it hit 70000 miles, the tranny went out. The dealership said it was due to not flushing the transmission. So, I suggest doing what they say and save yourself 5000. Thats what they charge. The flush is scheduled every 30000 miles.
