Liberty Diesel

  • Automatic transmission
  • 15,000 miles
The contact owns a 2006 Jeep Liberty. In September of 2006, the engine module in the contact's vehicle was repaired under recall. After the repair, the transmission would not shift properly. The repair also caused the motor to rev very high and the vehicle to pull harder and idle. The vehicle would accelerate from 5 to 10 mph when the accelerator pedal was not depressed. The failures occurred each time the vehicle was driven. In snowy weather conditions, the failures worsened. She took the vehicle to the original service dealer and another dealer, but they both would not reset the module again to remedy the issue. The contact spoke with the manufacturer and they stated that they could not assist. The NHTSA campaign id number was unknown. The current mileage was approximately 70,000 and failure mileage was approximately 15,000. Updated 03/12/09. Updated 03/16/09.

Liberty 4WD 4-cyl Diesel

  • Automatic transmission
  • 5,300 miles
After purchasing my diesel Jeep I noticed a shuddering in the transmission at about 55-65 miles an hour. Considerably worse with you decelerate after acceleration. In a construction hold on traffic my vehicle idled for about 10 minutes. When I was cleared to move forward I put the gear selector in drive. The Jeep stalled. It took me a several attempts to restart the motor. I have done extensive research and have come up with one answer. Air is in the fuel. I have taken it to a Jeep dealer in ozark Alabama and in dothan Alabama. Chrysler tells them that the air in my fuel system is ok. I demand to know what is a safe level of air allowed in the fuel system. No one has measured the amount of air in the fuel system. Please tell me so I can have it measured because I have volumes. I am afraid it will stall out on me again. I have had a few close calls when the Jeep hesitated and choked after a long light and a train crossing,

My Jeep Liberty with the diesel engine performed well for the first three months, then upon accelerating to enter a freeway it sputtered and the check engine light came on. The dealership repaired it by replacing the egr valve and associated components. The same problem occurred on in another 4 months, and again 4 months. Every time the egr valve was replaced. The last occurrence was in November 2006.

Liberty 4WD 4-cyl Diesel

  • Automatic transmission
  • 5,240 miles
The vehicle is a 2006 Jeep Liberty 4X4 equipped with the 2.8L crd (diesel engine). From an intersection at a complete stop, I proceeded to turn right into another street. I accelerated to approximately 15 mph when the vehicle suddenly lost all power and would not accelerate. The engine began to hesitate and the vehicle could not go faster than 5 mph. It could only limp along at this speed while I attempted to get off the road. This created a serious condition for other drivers to attempting to avoid my vehicle until I could reach a section a that allowed me to pull-off the road. The vehicle then stalled when I came to a complete stop. I attempted to restart the vehicle after a few minutes, and it ran in a normal manner. I subsequently continued my trip without any other incidents. This is a very disconcerting defect because it exhibits no signs that allow the operator to take preventative actions to avoid possible accident during road use.

Liberty 4WD 4-cyl Diesel

  • Automatic transmission
  • 530 miles
This is a new Liberty crd (diesel) with 610 miles that was accelerating from a border patrol checkpoint on I-8 East of san diego. While accelerating to ~65 the vehicle suddenly lost power in heavy freeway traffic and slowed to 35 mph even though the engine was running good. This sudden loss of power caused overtaking vehicles to swerve violently to avoid an accident including at least 2 panic stops. When the vehicle was safely on the shoulder (engine was idling fine) the car was shutdown and restarted which apparently recycled the computer and cleared the condition. Vehicle has performed fine since that incident.
