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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The contact owns a 2006 Jeep Liberty. The contact stated that the vehicle was misfiring abnormally and was taken to the dealer for repairs. The dealer made repairs to the engine and released the vehicle to the contact. While driving 25 mph, the check engine light illuminated and the vehicle was taken back to the dealer. The dealer advised the contact that the engine was misfiring due to valve failures within the engine block. The vehicle was not further repaired as the authorized dealer planned on further examining the vehicle. The failure and current mileage was 45,000.

2006 Jeep Liberty 4X4 engine misfires due to poor valve design with only 26,000 miles on the vehicle. Found codes po 301, 302, 303, 304 (cylinder misfires). Removed cylinder heads and found intake valves to be failing, replaced intake valves and keepers and lapped valves. Chrysler knew about the problem, redesigned the valves did not issue a recall notice and the vehicle is now 4 months out of warranty.

Liberty 4WD 4-cyl

  • Automatic transmission

I have had multiple problems related to the back lights on my 2006 Jeep Liberty renegade 4X4 vehicle. I purchased the car new with no miles on it. Recently, the gas pump was leaking and a valve was installed to stop the oil from leaking. The back light rack had to be replaced twice in two months. The back lights have gone out numerous of times.
