I have heard this is a very common problem with the 3.7 Jeep motors. From what the mechanics have told me is the lifters pop loose in the head and the engine sounds like it has blown. The lifter rattles around in the cylinder head making all kinds of noise. My first one was in I think 2007 on passenger side and the lifter jumped. To replace the broken parts was over $600 and my second one on the drivers side destroyed everything in the cylinder head. The vehicle is sitting right now because I don't have the money to fix it so I don't know if there was external damage done as well. This is a very common problem on all of the Jeep blogs with the 3.7 motor in my 2003 Jeep Liberty and should be recalled to fix the problem for free.

Ever since my issue with the headlights and foglights turning on/off began, I have a constant relay clicking noise to the left side of my steering wheel and my idling RPM's dropped.

Wife was driving vehicle on rural road. No warning lights or buzzers but noticed engine temperature was increasing. She identified a parking lot a few miles up the road where she planned to pull into since the road did not offer a shoulder. Just before reaching the parking lot the engine stalled out and she smelled oil. With the loss of power she immediately lost control and almost collided with the oncoming traffic. She was able to correct her steering before an accident occurred and coasted into the parking lot. She contacted me and we walked through the incident and she opened the hood. She described the engine compartment completely covered in smoking oil. I also reviewed the engine when I went to retrieve the vehicle and noted that it had apparently seized because the belt was off. The dealership was contacted but remains elusive to any problems with the engine even though there is an increasing amount of complaints concerning these engines premature failure due to "engine sludge" available online. Thank you for your time in reviewing this potential safety issue.

Vehicle was maintained. Oil changed on a regular basis and now oil is leaking into the antifreeze. Mechanic said it needs a new engine. These Jeep are junk. Obviously there should have been a recall.
