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 vehicle was taken to an independent mechanic where it was diagnosed that the input and output speed control sensors failed and needed to be replaced however, it was unknown if the vehicle was repaired.

When applying the brakes to stop the vehicle has spontaneously accelerated to a very high speed even though you are standing on the brake with both feet. The back wheels are spinning out of control, burning rubber, and you have to put the vehicle in neutral and turn off the engine. It happens intermittently and has happened several times (all on city streets). We have had two different modules replaced (don't remember what they were called) and it continues to happen.

On July 23, 2015, while driving on the interstate highway, at approximately 55 miles/hour, the odometer, speedometer and cruise control simultaneously stopped working for no apparently known reason. When arriving at my destination in another state, (approx. 60 miles), I researched the internet for potential problems. A number of other 2002 Jeep Liberty owners had experienced similar problems. Additionally, several owners had experienced engine stalling when braking at a stoplight or intersection. On July 28, 2015, when traveling on an interstate highway, I pulled off to the safety lane to take a telephone call. While I was slowly pushing on the brake pedal to move safely to curb lane, the engine stopped working, as did my steering. Quick thinking - having read prior owners' comments - told me to put the car in neutral and turn the ignition key on. That worked! I got the car safely to the side lane. I am in the process of getting problems corrected; however, other owners have stated that the problem of stalling persists.

The contact owns a 2002 Jeep Liberty. The contact stated that while driving approximately 45 mph, the vehicle stalled without warning. In addition, the contact stated that the vehicle accelerated independently without warning.

The contact also mentioned that another vehicle crashed into the rear of the vehicle. As a result the contact crashed into another vehicle. The air bags failed to deploy. There was a police report filed and no injuries sustained. The vehicle was taken to an independent mechanic, but was not diagnosed. The front end was repaired.

I was driving on the highway with cruise control on doing about 60 mph when suddenly the Jeep Liberty started jerking and the RPM needle arm and the speedometer arm started going crazy up and down. The Liberty started to slow down so I had to press on the gas pedal to maintain speed. The speedometer quit working and so did the cruise control, the auto door locks also quit working. The motor also started to die whenever I slowed down or come to a stop at a stop sign or red lights. Where its dangerous is when I am slowing down to make a turn and going in to it or half way in to it the motor dies and I lose the power steering. It takes alot of strength to complete the turn safely. I took the Liberty to a repair shop where they hooked it to a analyze machine. It said the speed sensor was bad, I had it replaced but it didn't fix anything. I took it to the dealer where I bought it, they told me it could be hundreds of dollars just to try to find out what is wrong with it. Recently I checked in the internet and saw that there are hundreds of other 2002 Jeep Liberty owners having the same problem. Speedometer quits working, motor died when you slowdown, and replacing the speed sensor doesn't fix anything. Its dangerous because you can crash when making a turn and the motor dies and you lose your steering. I know I have had some close calls. I hope you will check in to this problem. Just check in the internet and you will see alot of people have it with there 2002 Jeep Liberty. Thank you for your time.

Speedometer, cruise control, brake warning lamp and ABS light on, mileage counter not working, check engine light on as well, car dies or stall when slowing down even on hwy or when turning. We have replaced almost everything we can think of. Look online and hundred if not thousands of owners have exact same problems and no solution to problem. How are you supposed to have vehicle inspected if the emergency brake lights wont go off? we have replaced front and back brakes, master cylinder, wheel cylinders, speed sensors front driver and passenger and rear one. Fuel pump fuel filter have now been replaced. We have replaced more but I know we have spent well over 2 grand and nothing please help we are not the only ones having this issue.

While driving I activated the cruise control at 57 mph. The Jeep kept accelerating. The speedometer read 50 mph. I tapped the brake to disengage the cruise control and the speedometer jumped up to 70 mph. I did this a second time with the same results. I've had this vehicle a year and may have had this happen one other time. I got a ticket for going 68 mph when I thought I was going 50 mph. I got a $110 fine. I cannot recall if the cruise control was activated at that time. I owned the vehicle for a few weeks then.

2002 Jeep Liberty sport, speed sensor failure causes speedometer to stop working or fluctuate till it stops working. Check engine light comes on, engine will stall while driving with a result in loss of power steering, loss of power brakes and steering wheel locks up. 3rd time I've dealt with this issue in 5 years. The wiring in the harness constantly rubs and eventually becomes compromised to the elements, thus causing a short. I've managed to avoid any type of accident since I experienced this issue more than once!! Jeep has not acknowledged this is a safety issue and continually ignores the potential danger in a faulty design.
