Filed Mar 24, 2020 · Engine · 125,000 miles · TX

Engine failure. While traveling at 75mph on the highway, the vehicle lost power and threw a check engine light. I pulled over to the side of the road and shut off the vehicle and attempted to restart it. The vehicle did not immediately restart, but did so on the second try. I drove away and approximately a mile down the road, the vehicle began to knock and make banging noises, I pulled over once again and called a tow tuck. Vehicle was later diagnosed with failed rod bearings and required a full rebuild. Vehicle had 125k miles at the time of failure.

Driving home friday night engine started hard knocking and had catastrophic failure. Thrown rod. Called local jeep dealer and corresponded with mother ship jeep - told me to pound sand. Mentioned something about it being a canadian car and no warranty - how would I know that?

Bought jeep new. Has always needed oil between changes. Constant ticking sound started a few weeks ago while engine was running. Mechanic says engine needs to be replaced.

I own a 2011 jeep wrangler rubicon unlimited which I purchased as a new vehicle. It presently has over 90,000 miles on it. Recently, I noticed a ticking sound coming from the motor - detectable from outside the car, but not noticeable when driving. A fellow at a car wash mentioned that he had the same issue with his jeep and said that the issue turned out to be "valve lifters" and that the problem was resolved under the car's drive train warranty. I took my car to a dealer in for a regular oil change and asked to have the ticking sound checked by a mechanic. I was told that the sound was coming from the "top end" of the motor - and would have to bring it in again for a more lengthy evaluation - which I did. I made an appointment for service - took the vehicle in - and rented a car for what I expected to be several days of service. That was about a month ago. Subsequently, I've been told that the repairs to the top end of the engine did not resolve the problem and that the entire engine would have to be replaced. The dealer apparently ordered a "long block" replacement engine from chrysler, but has been having problems obtaining other parts that are involved in the repair. The dealer also told me to contact chrysler's warranty guys about seeking some relief for the cost of the car rental - which I did, but to no avail. I should add that I have been continually assured that the engine replacement is covered by the car's drive train warranty. However, I also came across an article in "autoweek" detailing problems chrysler was experiencing with jeep engines of my car's vintage - and that the engine replacements were being exacerbated by failures in chrylser's parts supply chain. This had resulted in both nhsta's involvement and to payments to other owners to offset the financial burden of the attenuated warranty repairs. I'm reporting this on this basis.

I started to hear a knocking noise for 3-5 seconds on a cold start. It did not do this on any sequential starts for that day. Took it to the dealer, who changed oil filter and oil. Still made sound on receiving vehicle. Took in again and dealer replaced the lifters. Still made noise upon receipt. Took in for a third time, they are now saying it is a normal noise, even though it never made it before. Jeep specialists say that this is a normal noise as well. After researching on-line, I have found a large amount of information leading to a malfunctioning cylinder head on the exact make and model of my jeep engine. There have been thousands replaced, but for some reason this was not even considered for my vehicle.
