Thumbs down 2007 Wrangler / 3.8L excessive oil consumption

I bought a new Jeep 2007 Wrangler Unlimited Sahara a few years ago. I live in Fairfield, CT. I went to SCAP Auto, in town.

The car was fine for a couple years until we started noticing the oil consumption was unusually high. We’d get it changed here and there and time went by. I started a job away from home and began using my car more regularly. It was then I took it to get a check up and the engine was nearly EMPTY of oil. Not b/c of lack of care, but because a certain lot of these cars are lemons.

After trying to work with Chrysler who said "go away we don’t care…” I took to the web.

*Apparently this is a HUGE problem for all owners of this type of Jeep / Engine/ Year. Jeep began making the cars in Mexico.*

Some minor digging has divulged this:

Jeeps made in this year timeframe have oil control ring / oil burner issues where they were put in upside down and instead of holding the oil in, it lets it out. They no longer use this Mexican plant to manufacture Jeeps. That's not helping the few of us that got these lemons.

Jeep will do nothing for the hundreds of us experiencing the problem. I was thinking of trying to arrange a class action lawsuit, as I’ve tried working directly with the company to no avail. I’ve already spent thousands "repairing" the engine when I was told it would keep happening and I should replace the engine and another thousands of dollars later I'd be whole. That’s making a pretty expensive Jeep, outrageously expensive.

Shouldn’t a consumer expect their engines to be manufactured in the correct way and the oil control rings NOT be installed upside down?

Jeep is running. I'm adding oil all the time. But basically need a new engine to cease this nonsense, and this is all because the parts were put in upside down, and Chrysler sold it that way, anyhow. And I trusted them and bought it that way, unknowingly.

Many are in my situation. Google it. I ran into a guy with this same issue a couple months ago in Trader Joe's Fairfield Parking lot.

We Are Legion.

Unfortunately, this isn't a big surprise. It's been talked about regularly for years. In fact, one of your references actually came from this forum.

According to the service manager at the Jeep dealership where I first asked the question, Chrysler says that oil consumption on this engine is within limits if it doesn't exceed something like a quart every 1,000 miles (I don't remember the exact number, but it was something like that).

When I had my 2008 it was a hassle for sure, and I would have been pi$$ed if I'd bought it new, but as it was I just lived with it and warned everybody that started a forum thread like "Thinking about buying a 2007-2011 wrangler, what should I look out for?"

I'd be happy to see some cash back, but I don't see how you'll ever be successful in a class action suit on something that came with a warranty that ran out years ago. Maybe I'm wrong....

Hi! Thanks for the reply.

Well, normally I'd agree with you, but legally speaking I bought a new car. There is no warranty for crazy stuff like this. This is not one of those normal wear and tear deals, but an extraordinary error as in: built it totally upside down in Mexico.

A reasonable man might assume that the car bought new would be fit for purpose for a reasonable period of time, and assuming the car was not driven in a way it was not intended, as in a rocket ship, or for drag racing... it should work as intended.

When parts are installed upside down allowing oil to leak out...well, a reasonable man might assume that the purchaser of the vehicle could expect to be made whole.

If I bought a blender, and the blades were installed without bearing oil and it blew up, would I not be eligible for a replacement? Would said blender company not be liable for selling me a faulty blender?

Think of this as a big freaking expensive blender, that I need to get to work.

Just spitballing here.

I don't want money. I just want a working Jeep Wrangler with parts installed as intended in their correct and proper position with an oil control seal that actually is in position to control oil. They'd have done better to leave it off entirely, rather than direct and siphon all the oil out of the engine entirely. Like a bloodly red carpet for oil drainage.

Sorry. vent vent vent.

I am told the 3.8 L engine was never manufactured in Mexico. This is from a Chrysler tech.

Love it.

I'm a fan through and through. I'm a WWII WWI buff, a military aircraft nerd and so of course I'm all about Jeep. It's just such a crock of malarky that we have to put up with a manufacturing defect. Extra oil I can handle. This is beyond ridiculous.

The engine is the most important part of the Jeep. If the defect is threatening it, then c'mon, we're just supposed to accept it? Sure, Build it upside down. Whatever I'll buy it.

NO I say! Poppycock.

Intriguing. I'm just coming from my guy. I'll have to do some more research when I'm not off buying oil, you know in my spare minutes... Hahaha....

The earlier Jeep wrangler engines were once 4.0s, and they stoped using them in the 2006 model year.
Then......in 2007 (my freaking year) they changed to the Chrysler engines (from their minivans ...the Dodge Intrepid, Chrysler Concorde and the Eagle Vision) to the the dreaded Chrysler's 3.8L OHV V6 and used that in the 2007+ Wranglers.

Yes. Minivan engines.
