3 Service Brakes problem

Failure Date: 04/29/2021

2008 Mercury Mariner. The vehicle sporadically and intermittently brakes while driving and accelerating. This was a reported issue many years ago on these cars but Ford never issued a recall even though there are a number of braking issues with this vehicle. This makes the vehicle extremely dangerous to drive if your brakes without warning lock up. I contacted the local dealer and Ford corporate and they were of no help. I also filed an incident report with Ford corporate #cas31601808.

4 Service Brakes problem

Failure Date: 01/30/2021

The abs hydrolic control unit has malfunctioned resulting in faulty brakes and dangerous driving conditions. I have to put the brake pedal to the ground to get any type of braking to be done. This takes extra seconds that could result in an accident if I had to suddenly brake. This seems to be a common problem and many Mariners and escapes have identical problems. I would like my VIN to be added to the recall list to have this problem fixed.

5 Service Brakes problem

Failure Date: 06/10/2020

I started having problems with my brakes. When I step on the brake the pedal would go almost all the way to the floor. I would react by pumping the brake which would make them work. I didn't drive with the brakes doing that very long because I took the car to a repair shop and I spent 450 dollars on brake work with being told that the problem was with the abs system and the disabled the abs system so that it didn't interfere with stopping the car. There have been recalls on other Ford products because of abs problems. The problem occurred while I was driving every time I wanted to stop and when I stopped for a light I felt like the brakes might quit working and the car could enter the intersection.

6 Service Brakes problem

Failure Date: 05/16/2020

My 17 year old daughter came home saying a message was on her dash about her brakes in our 2008 Mercury Mariner hybrid. I was about to leave so I decided to take her car, as soon as I pulled out of the driveway and started down the hill we live on, I noticed the brakes didn't feel right, I pressed all the way down to get the car to slowly come to a stop, as I did this, I noticed a warning sound and the message on the screen said check brake system, regen brakes disabled. I immediately turned the car around and went home, when trying to stop in our driveway, again the brakes were not working properly causing us to almost hit the other car in the driveway. This is extremely concerning as this car is our 17 year old daughters car. Once you get the car to stop, if the car is powered off for a few minutes and back on the brakes work again. This is a safety issue and seems to be a common problem. This happened yesterday 5/16/2020, the car has 120k miles.

I lost all braking ability and the pedal goes to the floor. This is a Mercury Mariner hybrid and Ford escape hybrid issue, it doesn't affect the non-hybrid models.

This had been a great car for me until today. I learned the hydraulic control unit is bad and will require nearly $5000 to replace. It is not safe to drive. It had 105000 miles. It is not worth much more than $5k. I have no choice but to try and trade the car in. I laterally just gave it to my daughter for college on Saturday. She has always loved my car.

13 Service Brakes problem

Failure Date: 06/01/2015

The anti-lock brick module has stopped working. The part alone is close to $1,200 to purchase. Upon investigating this problem we find that it is very common and tens of thousands of Ford built cars of this vintage have the same issue. Why hasn't there been a recall for such a common and critical issue?.

15 Service Brakes problem

Failure Date: 08/24/2011

Traveling at 35 mph and up , sometimes the vehicle would shutter and shake. Found a broken ring on the axle caused this problem. Took a few visits to the dealer to find it. It is very scary when it happens and you must pull over and shut the car off. Sometimes it would be weeks before it happened . Also, happened on the highway. This should have been covered under a safety recall. I had to pay for this repair.

16 Service Brakes problem

Failure Date: 06/29/2010

2008 Mercury Mariner. Consumer states safety issues with rotors the consumer took the vehicle to a mechanic to have the vehicle inspected. The mechanic stated the rotors for the front disc brakes were worn, pitted and rusted and needed to be replaced. It was verified when it was discovered that the brake pedal pulsed at speeds of 30 or 40 mph. The consumer then took the vehicle to the dealer who then asserted that the mechanic was wrong and that all vehicles have rust on their rotors. The consumer then took the vehicle back to his mechanic because of a continued pedal pulsation beginning at 30- 40 mph. The consumer then went to another dealership, who did indeed agree that the front rotors were rusted, pitted and unsafe. Also the rear drums were cracked and needed to be replaced. The abs was inoperative due to the tone rings had fallen off.
