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.

Repeated failure of radiator and thermostat housing. Annual replacement plus the heater core deterioration due to ph levels. Bad design. Safety issue as a failed radiator blows up steam and blocks view in motion in unsafe.

Drivning on interstate in Ohio after stop at service plaza and just got off ramp pulling onto interstate and oil light popped up and at same time engine made a noise. Immediately pulled off road. Turned off Jeep, called aaa. They towed me. I'm told it needs a new engine. I have records of good care of this vehicle. It only had 56,500 miles. I'm finding out others online others went through same. The garage tells me that Jeep knows of the problem and put a new upgrade to engines. These engines should have been recalled. Now I'm facing thousands for a new engine and I am without a vehicle. I have contacted Jeep and waiting for a response.

I bought my Jeep with 67,000 miles, within a year before reaching 100,000 miles it was only at about 99,000miles when this happened and apparently the engine wasn't lubricating correctly and a bearing in the engine shattered. Even though I change my oil every 3,000 miles with high mileage because my spouse works on cars he is always making sure. After looking into this further this engine is known throughout the Jeep community to fail before reaching 100,000 miles yet Jeep still has not used an extension for the engine. I spent almost 20,000 dollars on this vehicle one year ago and now I'm driving around with an engine that will fail soon because I have to get to work somehow and the warrenty on the vehicle was only a five year 100,000 miles warrenty so it doesn't cover it. I think Jeep should be ashamed for selling people these engines knowing they will fail before 100,000 miles and that they should be responsible and extend the original warranties to 10 yr 150,000 miles for people who expierience this kind of engine failure and now have to purchase a new engine out of pocket. I need someone to contact me regarding this issue I will not sit back and remain silent until it is resolved. I am a single mother living on limited income and have to take from my savings to cover an entire new engine. For a car I bought 1 year ago and didn't even go 100,000 miles before exploding. And I didn't even put the most miles on it. I've only gone about 40,000 miles. So in reality this was most likely an issue before I bought the vehicle.

I was driving down the road going 55 mph and a huge gust of white smoke came thru the dash vent system so I pulled over and got out of my Jeep sahara and noticed a big mass of white smoke coming out from under the hood... 2 minutes later, fire started and within a couple minutes my whole front part of the Jeep engine was engulfed in flames. Than from there it burned up the rest of the Jeep.. this vehicle was completely destroyed in a matter of 10-15 minutes.. I was driving on a paved road in the country..

A D V E R T I S E M E N T S

I have a 2011 Jeep Wrangler unlimited rubicon, I bought it new and it has not been off road except in a field or two and the only mud it has seen is from the road. It has not been lifted nor does it have over sized tires. I have had my electronic stability control light come on a few times in the 6 years I have had the vehicle, but it has always went right back off. It and the ABS came on a few weeks ago and will not go off, because it thinks my vehicle is sliding or spinning, the right front brakes will grab and it cuts the power to the engine. Today I was pulling out onto a main road and the brakes were acting like the ABS(that warning light is also on) was pulsing, I could feel it in the pedal. As I hit the gas to pull onto a very busy highway, the ESC light started flashing and cut the power to my engine and I could not go. As I was in a merge lane I was able to quickly cut to the right and get back off the road before I was hit by another vehicle. This is not the first time this has happened since this problem has been going on. I have had the Jeep to the dealership and they ordered the wiring harness (broken wire they said) to fix it 2 weeks ago and they haven't contacted me that it is in yet. But I was told that because the wiring is ran through the frame they have to pull the body off to replace it. Yes it is going to cost a lot to fix, but I will also have to arrange to take it to the dealership(which is about an hour away) and until I am able to do that, I still have to drive it. I contacted Jeep and talked to someone with their customer service about the concerns I have with being able to pull into traffic and the brakes holding me back and asking if there was a recall for this problem, but they said no and wasn't really concerned about it. And also, the warning lights come and go, flash and it won't go, as it did today when I tried to merge into traffic.

I was driving at under 10 mph, on a Texas state road when the plastic fuel line which is connected to the underside of the body with some type of adhesive failed. This dropped the fuel line directly on the catalytic converter, which melted the fuel line causing a fire that spread to the engine compartment. Apparently this is an issue on the 4 door model Wrangler as the 2 door Wrangler have a plate preventing this. This issue should be looked at on all 4 door models, ranging from 2008 through at least 2013. I have looked at other 4 door Jeep and see that they have the same potential issue there is nothing that prevents the fuel line from coming into contact with the exhaust and potentially causing a fire.

1. last year I had to replace my engine because Chrysler said it ran low on oil which caused engine damage. I had 11 oil changes and proof of service from oil change shops that entire year. I paid the 8K to put a new engine in to get it out of stevens creek Chrysler Jeep and Dodge. I was told to take Chrysler to small claims court. I never got a chance to because I could not "serve" anyone at Chrysler corporation properly. 2. the new engine that I bought had the same problem. They did an oil compression check and it lost all of its oil in 1000 miles. My car is in the shop now. Chrysler will come back and probably replace the engine for free this time. 3. while my car has been in the shop this weekend, it was broken into. Both windows broken and speakers stolen. The dealership said they would pay for this and fix it. What I want is not a new engine. I want my money back for the entire Jeep since they sold me a car that has had two blown engines now and I have all the reciepts to prove the first time I was not at fault. I do not want to take Chrysler to small claims. I want it done for me. I cannot get to the right people at Chrysler in order to push this further. I spoke to a few lawyers and they said it isnt neccesarily a lemon law case but it is more of a dealership/Chrysler warranty case. What can I do? thank you. Here is a link to my receipts for oil changes (I will put receipts up on server for costs soon) https://www.dropbox.com/sh/vh0B4cxxkcb36at/aabtpuwdk1zvc3frhxd6yjtta?dl=0

  • 84,000 miles
On two occasions, within a two week period, the vehicle continued to accelerate after the accelerator pedal had been released. The most severe occurred while passing and overtaking another vehicle. The application of the brakes and the parking brake did nothing to stop the acceleration. During the intended passing the vehicle reached 70 mph. The unintended acceleration took the vehicle to 85 mph. Eventually the vehicle stopped accelerating and was driven to the side of the roadway.

The engine cunsumes oil at a very high rate! told 1 quart every 1,000 by the dealership! in August 2013 while driving on a highway I had a rod baring snap and shoot metal chips into the oil pan at 52,000, the whole engine locked up and needed replaced. On May 7th 2016, again driving on the highway at 56,000 miles on the new engine, same exact thing rod baring snapped, metal hips into the oil pan, engine locked up and needed replace! the dealership inspected the oil pan and I was told there was absolutely no neglect on my part! I always has the oil changed between 3,000-5,000 miles.. I was told by the dealership this is a common issue. I can not believe this engine has not been totally recalled!!
