Example complaints

“The warning lights had come on a few days ago stating to check the brakes. Today, when the engine was started, the message stop safely now came on. This does not tell me anything about what I need to do and how critical this error is. Can I drive it to the repair shop or should I have it towed? What has to be replaced? This car is driven by my son who is an inexperienced driver, so this is a major concern.”

“I put my 2006 Mercury Mariner Hybrid into reverse to back out of my drive way. I applied a little gas and began rolling down the incline towards the street. As I approached the street I put on my brakes, but nothing happened and I failed to slow down. A code displayed on my dash reading, regen brakes the last word was either failure or disabled. I can't remember because I was in a panic about my brakes not working with my family in the car. I applied the brakes again. The brake pedal was hard to push and though I tried with all my strength, it did not stop the car. …”

“In stop and go city traffic going about 1 mile an hour I braked but my mariner didn't and I slowly rear ended another vehicle. My ABS sensor went on then off eventually an ABS regen light came on and I had no brakes so I drove ,very carefully, 83 miles to my ford dealer ( with no brakes) to find out that I needed a complete replacement of my ABS hybrid braking module. $3900! My mechanic and I called two different junk yards where we received replacements and they were installed but when brought back to the ford dealer the units wouldn't take the computer code and the (used) systems failed. …”

NHTSA complaint #11204696, filed 2019-04, 157,500 miles

“I have a Mercury Mariner Hybrid 2006. Coming up to red light and vehicle suddenly had no brakes, the pedal would not push in either. No lights had ever come on and no warning signs were ever received. The car was in great condition and was regularly taken care of and had preventable maintenance. Upon failure to brake I had to maneuver the vehicle in dangerous conditions just to avoid an accident. Lucky for me this time did not result in an accident or injury. After replacing the master brake cylinder (as per ford recommendations) I again had the same problem. …”
