Mercury Mariner grinding brakes problems

Filed Jul 17, 2025 · Body, Suspension · WI · crash

Drivers rear shock rusted off the wheel well causing wheel to snap and metal frame to hit the ground while I was traveling 40 mph. At this time the other wheels locked up and started squealing causing loss of control of vehicle shooting me across lanes and hitting curbs on both sides. This was heard all the way inside a church and they came running out. If I had not been able to gain control it would have flipped. The vehicle is available for inspection. It has not been reproduced or confirmed by a dealer or independent service other than the tow truck attendant telling me that the car need to be junk because it could not be repaired. The component has not been inspected by the manufacturer, or insurance company as it only has liability insurance. A police officer did show up on seen to direct traffic around vehicle and did see the issue but no report was taken. There was absolutely no indication that this was an issue until a few seconds before it snapped and that was the wheel started to wobble.

In march 2018, I noticed the steering wheel would shake when coming to a stop sign or stop light and make a grinding sound. It continued to do this every time for a couple weeks. Then toward mid march, I was backing out of a driveway and the power steering totally went out.it stated on panel "power steering default assist." it took extreme effort to steer the wheel to the side as the steering wheel was extremely rigid. Because it is a safety hazard to drive, it has only been driven to move car in apartment parking lot. I got this vehicle in june 2017 from a car dealer with no warranty. Ford says this VIN # is not included in recall for torque problem with power steering failure. As this is a manufacturing defect and a safety hazard, I want this vehicle VIN added to recall list. If I drive it on open road, it will surely cause injury to my family. I can't even maneuver the steering wheel.

Slight grinding noise when making a hard left turn, as into a driveway. (relitively slow speed, not creeping)

My mercury mariner's idler pulley has already broken three times in the past five months. There must be a recall on this vehicle. The car is very good and too strong for that thin bolt in this part. Luckily, the fourth time it happened, the ford dealer didn't charge me for the new part, which also broke off two weeks later. It has also broken two belts already. Trying to solve the issue, I went to metric bolts and nuts, in wakefield, ma, and bought a higher grade hardened steel bolt/screw, and it also broke off a week later. Once again, two days ago, my mechanic put in another hardened steel screw. He added a nut near the bearing, which makes a squeaking noise, but it has not broken yet. I am now afraid to drive it far from home, because I have been towed so many times already. I have researched the internet and realized that it is a constant issue. Some people have reported the occurrence of this issue 17 times in less than a year. It is also the same frequent problem with mazda tribute, ford escape, ford fusion, etc. What does it take for a recall? Help! Help! Help!

Steering wheel shakes and grinding sounds coming from steering column this happens when the vehicle is in motion or stationary. Local ford dealership diagnosed as a faulty torque sensor which would result in a loss of power steering. Had a recall on the vehicle approximately a year ago because of loss of power steering due to the torque sensor. At the time of recall my torque sensor was not failing so the dealership only did a computer software update. Clearly the update did nothing to correct the issue with the torque sensor associated with the recall, however now ford will not correct the issue with the vehicle. I have not personally lost my power steering yet in a situation that could have caused injury however there are a whole slew of complaints from people reporting the exact same problem. A sudden loss of steering is a big deal and very dangerous, it is something ford should be required to correct.

I purchased my 2010 mariner 03/26/2013 from a local dealership. While driving at around 35 - 40 MPH I noticed a grinding sound and difficulty to increase speed. I then noticed that my left blinker was flashing at a faster speed and the tail light went out. That was replaced. The car then would sporadically go dead and would have to be jumped. I had 3 different service shops look at the vehicle and found no issues. I did replace the battery and it appeared to run fine for about 3 - 4 days. It is now sporadically dead and the local dealership will look into the issue on 8/7/2013. Undetermined problem at this time.

I own a 2008 mercury mariner and I am a little concerned with its safety. On 03/15/13 I was pulling out of my drive and the steering wheel would not turn. I proceeded to put in reverse to get out of the road and backed into the drive. I turned all power down then restarted the vehicle with no problems in the steering. I went to pick up my kids and the steering wheel started to pulsate and I could hear a clunking noise while sitting at a stop sign. Everytime I came to a stop it would do it. On sat. I took it to the local shop. We couldn't notice anything out of the ordinary that would cause this to happen. The only solution was the entire steering column would have to be replaced. I did some research on line to see if this was a known issue or if a recall had been issued. I was amazed at how many complaints have been placed and no recall has been issued. I set up an appt with the dealer for tues. I was working on mon. And left to run an errand for work and the next thing I know, I was driving 65 MPH on the highway and with out warning I lost all power in the driving and heard a loud grinding and then clunk. I thought the transmission went out! I immediately turned on my hazards to try and get off to the side of the road cause I was slowing down extremely fast. I was almost in a 3 car accident and luckily everybody is ok, but it could of been a lot worse! I was towed to a dealer. They confirmed my fears. The transmission went out with no warning. They told me this is a known problem but there was nothing they could do cause there was no recall on this! When I asked as to why, the said not enough complaints have been made! Wow, you have got to be kidding me?!? How many people have to die before these issues are addressed? Very unhappy because it's going to cost $5200 to replace transmission and the entire steering column! Hold ford accountable!

Vehicle steering began to grind and make noises during turning of steering wheel. Very loose steering as if steering is coming apart. Have reported to ford, but stated there is no recall on this, even though numerous complaints on here and over 550 on edmunds.com. Vehicle seems unsafe and only 68000 miles.

2009 mercury mariner. The rear end of the vehicle makes a squealing noise upon acceleration I took the car back to the ford dealership in hillsdale. The vehicle was in the shop 12/9/2009 through 12/16/2009. Unable to fix the noise, ford motor company had them tear down the transmission and replace the drive chain. When I picked up the car I was told that the noise was still there and that ford engineering said it should not be a problem. The noise was still consistent and has grown increasingly louder. Since this initial complaint I have received a recall notice for the transmission solenoid regulator valve. The vehicle has been accelerating when it shouldn't and not accelerating when it should, like when merging into traffic when the transmission would not perform properly.
