2006 Mercury Mariner Problems
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.
A defective power steering return line can cause a knocking noise when turning or going over bumps, especially when the engine has reached normal operating temperature. The power steering return line should be replaced.
A whining from the front while driving may be caused by the front axle shafts. This would be felt between 20 and 45 MPH, and the half shafts can be replaced with revised dampened axles.
Shock bushing failure in the rear can allow the shock absorber to contact the body and cause a squeaking noise over bumps in the rear. The faulty rear shock absorber bushings should be replaced.

2006 Mercury Mariner Reviews
This the second transmission, new u joints, tie rod ends inner and outer, new power steering pump (car still hard to steer). I will probally need a new rack and pinion and now the emission system light is on. ?? what next. Can't afford a new car?
I loved this car when I first got it but every time I turn around something goes wrong with this car.. I would never buy another mercury again I am going back to buying only Chevy from now on..
This car has been a maintenance nightmare. At 70,065 miles, the engine went, due to lack of lubrication making it to the top end. The cam shafts came loose, flopped around, and tore up the block so bad I could not get a core on it when I got a new engine installed. 6 days out of the 6 year / 100,000 mile warranty. Brakes went early, half shaft went at 40k, it's noisy and neither my fiance nor I feel like this car is well built. In the last three years, I have put 100,000 miles more (now at 175,000) on my 06 4runner, and have replaced only a turn signal, and I tow a 5000 lb trailer 30% of the time. Never again will I own a Ford product.
I have had this car for over 6 years. The only problems that we have had were a rear tail light went out and the battery was replaced after 4 years. Built well and very reliable. I remember reading the consumer report on this car and they had to dig and stab low to find a problem with this vehicle. I recall that they hated the "Faux wood trim" around the radio and A/C controls. The other excuse was just as lame. Americans do build a great product and it’s sad to see Mercury fade away.
Has been a great car. Drive it every day for work. Done regular maintenance and have had no problems.
