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.

2004 Jeep Wrangler Owner Comments

  • 91,500 miles


At 91,500 miles the PCM failed for a second time. I am not certain when the first failure occurred, but it was shown to have been flashed previously. This issue surfaced in the form of a stall out at a light. When attempting to accelerate from an idle position the engine stalled. After parking the vehicle, turning over the engine while simultaneously giving it gas, the vehicle turned over. According to three different mechanics this is a common issue among '04 Jeep Wrangler that they have encountered recently (12 years after market and 2 years completely out of warranty). No one can find a replacement PCM because they are no longer manufactured, and it was Chrysler's recommendation that customers experiencing this issue go to a scrap yard to find a replacement (likely to have the same issue). As a customer I am appalled that we are aware of this issue and there have been no recalls. Driving down the highway my battery charged to 20 volts and could have exploded.

I was driving and when I stopped the Jeep would not go into park. I found a piece of level ground to stop on but then since it would not go into park, I could not take the key out of the ignition. I was very lucky the dealer was open so I could drive it there to be fixed. They told me the center pin/shaft on shift assembly was broke. I ask if that wasn't a safety part and was told no even if it had been, the Jeep was out of warranty so it would not make a difference any way. The lady in write up said that was the second one they had to fix. I believe this could be a very dangerous thing. There was no warning that it was going to happen! I live on a hill and there was no way I could go home with it not being able to put it in park, I could not even get out of it in my drive way because of the incline. What's happen to the steel with which they make the car parts today?
