2007 Jeep Wrangler: excessive oil consumption

Filed Aug 22, 2017 · Engine, Seat belts · 20 miles · IL

The seat belts in the back when buckling are locked. Making it hard to move around. Since day the I bought the car. Took it to the dealership for repair and they said they found nothing. Only after my warranties were up did they say they would fix the problem if I paid for the labor. The engine has an oil consumption problem also from the first day I bought it, the dealership has covered it up again until the warranty was expired. They found 5 leaky areas in the engine.

Purchased 2007 wrangler sahara new. Maintained vehicle as suggested by manufacturer. Noticed early on the 3.8 l v6 burned oil. Was told this was normal, so I added a quart of oil every 1,000 miles. At 51,000 miles noticed a loud knock. Immediately took the vehicle in for service and was told that the engine was blown. I had changed the oil at 50,000 miles but somehow lost all of the oil in 1,000 miles. Never had a check engine light or oil warning light, no oil showing on the ground. Dealer wanted $7,000 to install remanufactured long block. Would not call chrysler on my behalf even though they had been the one servicing the vehicle. Chrysler refused any assistance since out of warranty. Three different customer service representatives refused to allow me to speak with anyone above them as the decision (made in one hour) was final. They refused to give me an address or fax number so that I could submit my service records to show that I had maintained the vehicle. In fact, they indicated that not only was a quart of oil every 700-1,000 miles was perfectly normal, that is was also normal to check the oil level at least once a week when fueling the vehicle. A quick review on the internet shows thousands with this problem. 650 signatures are on one petition alone that show this is a problem that chrysler refuses to acknowledge.

I purchased a 2007 jeep wrangler unlimited sahara. The dealership supposedly did an oil change and after 3 months and about 1,800 miles of driving my oil light came on. I checked the oil and it was low. I took it to a local shop(valvoline quick lube) to get an oil change and they mentioned the oil plug was stripped and that there was silicone caulk to help seal the oil plug. At this point I had them replace the oil plug and was content with the service. After driving 500-600 miles after the oil change I checked the oil and it was low as if it was disappearing. No visible leaks in my garage and none in my parking spot at work. At this point I had to add 2 quarts of oil to get to read on the dip stick. This went on until my next oil change and I had valvoline look for any visual leaks. They mentioned nothing that would explain the massive amount of oil being consumed. Finally, in march of 2013, took my jeep to a chrysler dealership to have them start an oil consumption test. After the first 500 miles they stated there was loss of oil and made there marks and resealed everything for the next 500 miles. I took it back in at the next 500 mile mark, now mind you everything is sealed so they know nothing was tampered with, performance chrysler called me and told me that there was significant oil loss and they stated the rings on the pistons are bad and need to be replaced at a cost of $3,300. My complaint is, my jeep at this point has 47000 miles on it and they are telling me the rings are bad. I've had vehicles that lasted 120,000+ and no problems with the rings on the pistons. I have talked to a couple of mechanics and said there should be no way the rings should have gone bad that fast.

My issue is the large amount of oil used, 1 qt used per 2500 miles. This is what the dealership and jeep told me. Normal oil consumption: below are industry standards for normal engine oil consumption: mileage below 50,000: normal oil consumption is one quart for each 1,000 miles driven. Mileage above 50,000: normal oil consumption is one quart for each 750 miles driven. So, as long as a jeep with 50000 or more miles on it does not use more than a quart of oil every 750 miles they do not care, and they will not fix it. I was also told that why new jeeps take 6 qt's since they use so much oil. I even have a warranty and they still will not fix it. There are no oil leaks and I have had 2 oil consumption test ran on the vehicle by the dealership. The dealership and chrysler will not help fix the problem. I was told by the dealership that I am lucky it does not use a quart of oil every 1000 miles, since it may get low enough to burn the engine up in under 2500 miles.

As driving on highway engine started to make clicking noise, called local jeep dealership and brought into shop no engine lights or oil lights on, service person told me that oil was 5 quarts low in a 6 quart engine and the engine bearings were stripped need new engine and life time powertrain warranty will not cover engine. When I ask service person why this happen he could not and would not give straight answer simple said " aftermarket oil filter, and I found no leaks" then asked if it was the oil filter he said " no I'm not telling you it was the oil filter!" then I said "if it is not the oil filter nor you found no leaks where did the other 5 quarts of oil disappear to. It must be a defected engine. I just change the oil 2000 miles ago!" in all service department will not tell me why the engine failed or how it happen neither will chrysler.

Intermittent problem occurring almost exclusively at highway speeds. While driving at highway speeds suddenly, without warning, the vehicle shuts off. All warning lights on the dash board appear, engine completely shuts off which leads to power steering failure and loss of safe control of the vehicle. While the engine shut off is intermittent and does not last for more than a few seconds before it turns back on without use of the key or any other means of manually restarting the vehicle, it is highly unsafe and can lead to severe injury or death. We have noted this issue occurring approximately 1-2 times per month. We finally took the vehicle to the dealership to service and locate the issue with the vehicle on october 20, 2011. The dealership stated they could not find any issues with the vehicle, with the exception of unusually high oil consumption. The dealership advised we do an oil consumption test which will be completed in 3000 miles or 3 months.

My vehicle spills fuel out of the filler area every time I fill up. The fuel gets on me, the vehicle, and the ground. I have contacted chrysler about the matter, and they advise me because I am outside the time frame for their tsb, any repairs would have to be paid by me. After thoroughly researching the matter, it seems this is a wide spread concern. Chrysler has addressed the issue for some, but not others because "we're outside the window". Please see your code #pe10032. Also, my vehicle consumes or burns oil at the rate of one quart per 1000 miles. Again, research shows this is another wide spread matter attributed to faulty motor construction of some 2007/2008 engines. Owners who have had the repair done under warranty found that on three pistons, ring gaps where in a line, the other three where close, all six oil expander rings and piston rods where installed upside down. Chrysler will address the matter only if you are still under warranty. I do not understand why the cost should be bared by the consumer when both matters are so common and wide spread as to indicate design flaws in the product. Why should I pay for their inability to build a component correctly?
