2007 Jeep Wrangler 4-DR 4x4: engine knocking or ticking

Filed Apr 8, 2019 · Engine · 52,000 miles · TX

There is an issue with the valve lifters that cause a ticking or knocking sound while stationary & in motion. Worse while in motion, we have been told by two different mechanics that to repair the issue the engine has to be disassembled.

Had to add oil at nearily every fillup. The dealer said that was normal to add oil every 1000 miles!!! Ended up short on oil, oil light never went on and trashed engine. It made a horrible knocking noise. I replaced it at a cost of $6118 as the car only had 49560 miles on it.

Death wobble!!! Death wobble!!! As I was driving down the interstate with heavy traffic, I hit a bump goin 65 MPH and suddenly with out any warning the front end of my jeep started rapidly wobbling back and forth across the road, nearly causing multiple accidents. It startled me severely, I was able to turn on my hazard lights and started to slowly decelerate while trying to steer to the shoulder. It took until I got down to 25mph for it to stop shimmying. I stopped on the shoulder to inspect the front end off the highway, checked my tire pressure, the shocks, axle and all other parts to see what broke. Everything appeared to be normal and I could not find anything that caused the sever wobbling back and forth of the front end, so carried on, very cautiously. This happens quite often, sometimes going as low at 45mph, but only when something in the road knocks it off balance. I do not feel safe in my jeep at all. The jeep dealer tells me there is nothing wrong with the jeep's suspension and I have had several independent mechanics tell me they dont know what to replace inorder to correct the problem that the only thing they have luck with fixing the issue is too replace the entire front-end along with the axle. This is the type of issue that this agency was established to correct. Something has to be done before people are killed due to a major enginnering defect by jeep.

As I was driving down the highway, I hit a bump and my whole jeep rapidly rattled back and forth across the road, nearly causing multiple accidents. It startled me severely, and I slammed on my brakes, slowly decelerating. It took until I got down to 25mph for it to stop shimmying. I pulled off the highway into the nearest gas station, checked my tire pressure and made sure there were no identifiable obtrusions that would affect performance, and carried on, very cautiously. This happens quite often, sometimes going as low at 45mph, but only when something in the road knocks it off balance. I do not feel safe in my jeep at all.

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 jeep stalling at all speeds !! Esp light will flash and car will began to jerk and stall. This problem appears very dangerous since it is not predictable. I have also noticed a knocking sound when this happens . I have read that the transmission is also being affected. Will chrysler address this issue before people get killed ? Dealership says there is no fix for it yet......please help !!!!!!!!
