It started with a slight knock in the engine at first start up. It would go away after a few minutes. That lasted about 3-4 weeks. Until one start up the engine would not stop ticking, by the time I arrived home the engine was knocking violently. Oil levels were fine. Had the jeep towed to the dealership to have the engine inspected, to see if it would be covered under warranty. The tech did an inspection and I was told that the engine spun 2 connecting rod bearings, bent 4 rods, damaged 4 pistons, damage to crank, and almost all oil passages in engine were clogged by metal debris. This was the first time the factory seal on the engine was opened. The dealership contacted chrysler and told them the situation. I spoke with chrysler many times over the month span that the jeep was at the dealership,I also had the dealership fax almost 20 other cases to the claims dept. That I have done research on the same situation and provided the vehicle year, make, and mileage including all of my sources. Chrysler told me that they would not cover the engine repair because of the mileage and that I was not the first owner of the vehicle,the jeep has 53k on it. No one at the dealership could tell me the reason why this happened, or how I caused the engine to self destruct. I was told by another mechanic that the oil ports inside the engine going to the crank were designed too small, and this is why the crank bearings were failing. I have taken the jeep to another mechanic, he advised that a new engine should be installed. He tried to order a new engine from his supplier, but was told they are on a national backorder and that it would take about a week to receive a new one. He was told that chrysler is very aware of the situation and has refused to take any action as of now.

My complaint and warning has to do with our 2007 jeep wrangler unlimited,saraha, 3.8 litre. We had a pre-mature engine failure in our jeep due to improper engine assembly during manufacture of the engine. The engine failure was due to the pressure relief valve for the engine oil by-pass valve being installed in the wrong order, causing the engines oil being only partially filtered. This non-filtered oil caused the engine to fail due to the dirty oil passing through the engine and causing excessive wear of the engine. Our engine failed at just over 43,000 miles and the failure could be sudden and put anyone that has this engine condition at risk if the vehicle is in motion while the failure occurs. I want to be on record because I do not want anyone to be injured or worse lose there life over something as simple as warning the public of this issue found in our engine, and also to be on record because who knows how many engine were assembled this way which in my mind should be considered poor craftsmanship. Total details, cost and the full extent of damaged can be extended to anyone who needs or wants this information, if requested in writing or email.

1. No incidents leading up to failure of the vehicle being able to drive. 2. This is the 1st occurrence. A local mechanic verified a cylinder was dropped and advised to return to the jeep/chrysler dealership for warranty work. The vehicle is a jeep wrangler x unlimited 4-door 4x4. 3. 2 days later, jeep says there is "engine failure" when they saw that the vehicle would not accelerate over 30 MPH (2 days prior).

I have a 2007 jeep wrangler 4 dr x unlimited 4wd. I saw the recall notice for the vehicles stalling manufactured before jan 2007. My vehicle was manufactured I believe in may of 2007 and the stall has happened twice. Radio goes off, engine died and all lights on the dash came on and appeared to reset. It's a manual transmission and the engine restarted because I was moving and still in gear. It only lasts about 2 seconds but during the time it is doing this the power steering is not functional.(I only know this because I was on a curved freeway on ramp during one of the times it did this.) I am only filing this complaint because it appears the recall (g25 I believe) does not seem to cover the full range of dates for affected vehicles as mine was manufactured in may of 2007.

At a stop sign, the engine died. I tried to start it again, but the console remained blank and nothing happened. I had to push it off the road. After trying 5-6 more times, it finally started. There was no warning this would happened; it was very sudden. I'm afraid that this will happen on the highway. It could be very dangerous. The vehicle was completely dead for approx. 5 mins. The electric windows still worked during this time.

While driving on the highway at 70 MPH (cruise control enabled) the car started surging as if someone were pumping the gas pedal. It did this for approximately 10 seconds then the engine died. I was in traffic and it took a few seconds to figure out what had happened. I was lucky to have a manual transmission because the second I pressed on the clutch I lost all power steering and power brake function. I was in the middle of traffic and cars started passing me on either side. This could have easily LED to an accident. I will be taking it in to the dealer asap.

While driving the vehicle stalled while coming to a stop. As it idled to ~600 rpms the engine died. The car was restarted, and the vehical stalled again at the next intersection. The only light that was lit was the throttle control warning light. Preceeding this occurrence, on 6 separate occasions, the throttle control warning light would come on while driving. The only direction in the manual was to turn the vehicle off and then on again. I have seen several complaints about this stall bug associated with the 2007 jeep wrangler jk. I could only hope that this did not occur again, and am fortunate it occurred while I was at low speeds.

I was going down a steep hill on a remote trail with a half a tank of gas. After 10 minutes the fuel gauge showed empty and the engine died, I lost my brakes just when I needed them the most. I could not stop the car and we plunged down the very very steep hill with no way to stop or to steer. For some reason in a steep down hill the engine did notnot get fuel. Losing brakes and steering power just when it is needed the most is an accident and a law suite waiting to happen.
