Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The contact owns a 2004 Jeep Liberty. The contact stated that while driving 50 mph, the vehicle accelerated up to 75 mph on its own. The contact was able to decelerate. The failure recurred, and while depressing the brake, the vehicle accelerated instead of braking. There was a warning light illuminated with a symbol of a car and the contact was unsure of what that meant. The vehicle was taken to dealer; however an inspection or repair did not take place. The manufacturer was notified and no assistance was provided. The failure and current mileages were 72,000. Updated 08-07-12 updated 08/08/2012

2004 Jeep Liberty parked in parking garage. Put key in ignition and had foot on brake. Turned key on, put it in reverse and car accelerated out of control. Put second foot on brake and tried to stop car. Continued to accelerate. Front drivers side tire caught a pillar and between that and practically standing on brake finally stopped car. Took car to dealer in West valley ut. They could not repeat a diagnostic problem but did state the throttle body was dirty and cleaned it, along with $1575.95 worth of parts and labor. They replaced a bent steering gear. I had the car for 5 years and it never happened before. I wrote to Chrysler and they sent me a check for half of the $1575.95 damage. They did not include any other paperwork. I called them and they again would not put anything in writing as to why they did not pay the entire amount. I strongly feel that it was a problem with the acceleration system and I should be reimbursed for the rest of the money.

I was at a complete stop with my foot firmly on the brake waiting to exit a parking lot to enter traffic, when the Jeep started to accelerate into oncoming traffic. I was holding the brake down and I could hear a grinding noise as the car continued to advance into traffic. I took my foot from the brake and put on the accelerator to narrowly miss being hit broadside by a pickup truck. I called Chrysler and was told that she had never heard of this happening, but I have found many other peoples' stories online of the same problem.

2004 Jeep Liberty unintended acceleration. The consumers husband is a mechanic. Her husband and his employer were trying to maneuver the vehicle into the work bay, due to a broken ball joint the vehicle could not be steered. The consumers husband was guiding the vehicle with a floor jack, while the other mechanic was gently giving it gas to slowly move forward, when all of a sudden, the vehicle shot forward at full speed on its own. The consumers husband was dragged 15 feet then crushed against in an upright position. The consumers husband was seriously. Injured.

Our Honda civic was in motion when struck from behind by an out-of-control 2004 Jeep Liberty. The Jeep pushed our car for 1 1/2 blocks before veering to the right, taking out a utility pole and hitting 3 cars in a used car lot before coming to a stop. The driver of the Jeep stated the brakes would not work and the car was clearly accelerating throughout the accident.

The speedometer / mileage odometer have intermittently stopped working on several occasions. I brought this up to the dealership since prior to the vehicle going out of the 36mo/36000 mile warranty and was told there was nothing wrong with it, there obviously is. The final time they went out was on Nov 10th while we were going through the mountains of Tennessee on our way to nc. It has not worked since. After much looking on the internet I have discovered there are a lot of other consumers with the identical complaint on the 2001 through 2006 Jeep Liberty's. I then called the Chrysler consumer hotline and the first person I spoke with was very understanding and said that Chrysler would be able take care of it, he then transferred me to a supervisor to have the repairs authorized and the supervisor was very rude and said "Chrysler didn't owe me anything, and they would not provide any assistance". this is unacceptable to me as a consumer.

At about 5-6,000 miles my 04 Jeep Liberty sport's acceleration began to stutter at around 50 mph. If you drive consistently between 50-60 mph for a few miles and then try to accelerate the engine pressure drops, the rpms drop and the gas peddle feels like it's disappeared. Eventually it will catch and the rpms spike to about 4000 rpms and the car accelerates but in an emergency situation I feel that the cars acceleration will fail. I've brought it to the dealer on several occasions and every time the dealer can not replicate the problem as the problem happens only when you sustain 50-60 mph over a period of time.

: the contact stated when applying brake pressure the vehicle lurched forward. When attempting to make a low speed stop at a stop sign, the vehicle suddenly accelerated into traffic. The vehicle continued to accelerate even though brake pressure was applied. The vehicle struck a culvert, rolled 3 times and eventually came to a stop along the embankment. The contact was extracted from the vehicle by emergency services. Although the contact was wearing a seat belt, minor injuries were sustained. Upon initial impact, the seat belt released from the buckle assembly and the air bag did not deploy. A police report was taken at the scene. The vehicle was deemed totaled by the insurance adjustor.

This is follow-up to complaint 10145198. Just received letter in mail from diamler Chrysler that they could not find anything wrong with our 2004 Jeep Liberty. This is the Jeep that almost killed my wife when it accelerated without her pushing on the pedal. We are now sitting on a boat anchor that we can not get back in to. If anyone wants it let us know! we know of at least one other case of a Jeep taking off and injuring someone. I will again ask how many times has someone been killed or injured in a Jeep because of excess speed. Could this be what happened to them.

Driver had just completed turn on to an approach ramp to a 4 lane highway. As Jeep Liberty started down ramp it sped up with no pedal pressure. The Jeep pulled sharply to the left, the driver was able to correct but because of continued increase of speed hit guard rail on opposite side of ramp. The driver had both feet on the brake and held Jeep against guard rail for approx 300 ft before being able to stop. The uncontrolled acceleration had caused the Jeep to swerve side to side and it was only the skill of the driver that prevented this Jeep from going over the edge of the ramp and rolling over. The driver received a broken wrist in her effort to keep the Jeep on the road. The Jeep was taken to the local dealer and is still sitting there. The manufacturer has inspected the Jeep and told the dealer not to touch it. They have not responded to phone calls about what is wrong and when the owners may expect their Jeep back, in driving condition. The only answer the owners have received is the manufacturers legal dept has the file. The road on the date of this incident was dry and the Jeep had approx 27000 miles on it. The owners would like to know if someone can tell them how many more Jeep have had this problem and what is being done about it. How many deaths in Jeep are the result of excess speed. Could these be the result of this type of uncontrolled acceleration.
