2005 Jeep Liberty: brake failure

At approx 8:00 on the morning of 2/16/15 my 2005 jeep liberty, 3.8l v-6 with automatic transmission began to accelerate out of control while braking for a stop sign. The engine was cold, I had just started it and the temperature was in the mid to upper 50s. I was traveling about 27 MPH, and began to slow for the stop. At about 10-15 MPH, I noticed the car was no longer slowing down. It seemed as though the brakes stopped working. At the same time, the engine briefly revved on its own. This made the car accelerate. I could not stop at the stop sign and the car accelerated into 50 MPH cross traffic. I made a hard right turn to bring the car next to the curb, allowing room for traffic to go by. At the same time, I put the transmission into neutral and that allowed the car to stop. I then put the car into park and revved the engine. It seemed to respond normally at that point (engine would return to idle immediately after taking my foot off the gas). After shifting between part to drive, then reverse, etc. Several times, it still seemed to work normally so I continued to work with no further problems. It seemed as though while coming to a stop, the transmission did not down shift or disengage. As the engine rpms were reduced below idle due to the car slowing, the computer control system tried to bring the engine speed back up, causing it to accelerate. A couple of facts - the car has approx. 159,800 miles on the odometer. I purchased it used a few months ago and have put 13,000 miles on it. When I purchased it I had it examined by a mechanic and had all the hoses, belts, etc. Replaced. I've had the oil changed at about 5,000 mile intervals. I drive with one foot only, I don't use separate feet for the gas and the brake. The floor mat was not moved before or after this incident, and is not close to the gas pedal. Check engine light did not come on.

2005 jeep liberty ltd , was having brake problems. It was shimmying etc, when I put on brakes and at times the pedal went to the floor. I was involved in an accident when my jeep would not stop when I put on brakes. I rearended someone. I had a mechanic check this out before accident and could not find anything wrong. I have owned 3 jeeps in my life time and never had problems. I have a $3000 repair to my car because of brake failure, plus the airbags did not come out. I expect someone to contact me immediately.

The brakes on my 2005 jeep liberty failed in a mall parking lot and caused an accident. Only 1-1/2 months earlier I had rear brakes replaced at the suggestion of the dealership (mileage was 25,000 miles). The dealership near the accident site said there was nothing wrong. I took it back to the original dealership where I purchased the vehicle (twice), and they said they checked everything and could find no problem. The brakes failed twice since the accident; fortunately there were no vehicles or pedestrians around. There are times when braking that it feels like the brakes are slipping. I am afraid to drive the vehicle. Contacted jeep complaint line and there is nothing they will do because I have no physical evidence there is a problem. I stopped at the dealership a third time, and the service manager said it could be an intermittent problem and unless they are driving it at the time of the incident, they cannot help me. Consequently, there was $3,300 damage done to my jeep and I am not sure of the damage to the other vehicle. I had to pay $500 deductible, $100 for a rental, and my insurance rates will surely rise.

I was driving down my 3/10 mile private road, approximately a 12% grade with brake pedal engaged when suddenly the pedal went to the floor and the steering wheel locked. The car went 150' & down a 12' embankment head first onto a gravel drive and landed upside down. I was conscious at all times and crawled out the passenger side window. It was an hour before I was found. I had 2 broken legs & cracked 2nd vertebra. I spent 5 months in hospitals & a nursing home with a halo on my head & fixators on my legs. The car was totaled.

Dt: the contact complained about a brake problem. Since the purchase of the vehicle the brakes have felt spongy. When applying brake pressure the pedal went all the way to the floor. It stop the vehicle, but the pressure had to be firm enough to press the pedal to the floor. Contacted daimler /hrysler, and their technical service representative said some jeep liberties had this problem and some did not. They had no idea why this occurred. The dealership replaced the master cylinder free of charge, but the same thing happened again, the pedal must be pressed to the floor. The contact was concerned with the idea of losing brake pressure. *ak updated 11/29/05.
