Post subject:  Losing Power
New to the forum. I just bought an 05 Liberty CRD. I thought I did the research and I was buying a good jeep. Clean car fax clean auto check, the liberty was in great shape. I needed something reliable for work I put on a ton of miles, so i liked the mpg. Here is the problem 35 miles from the dealer engine light came. The dealer brought it back and replaced EGR valve, fuel control valve, a bunch of gaskets and rings, and reflashed the computer with some update. When they brought it back I mentions that I had lost power, I could only go about 30 mph. They fixed everything or so they said and for about 300 miles it was fine (one day of driving for me) then last night the power dropped off again. It's hard to tell if it is a fuel delivery issue or a transmission issue??? No noises no engine light, just no power. I press the pedal and the engine revs it hits the shift points but doesn't go any faster. Whats wrong is this a bad vechilce for high milage? I drive 40 -45000 miles per year way out to the middle of now where. Will this continue to be an issue. I can not afford to have it towed back to the dealer weekly not to mention the time off work without a vechile. By the way 05 liberty crd 52,000 miles. Any help or ideas will be greatly appreciated.

If you can have a diagnostic reader check the fault codes, we will be able to help you out to root cause the 'limp-home' condition. Certain codes will cause the engine to run at a lower power level until the CEL is cleared.

Sounds like the air in the fuel issue. Mine felt like the transmission was toast the first time it happened. Lots of revving, no shifting to high gear, and limping.

You can check for air in the fuel by pushing the prime button. It should be firm. You might want to change the fuel filter and you can get them at the dealer or NAPA.
Also a charged air hose will cause a lack of power. You can check these but the driverr's side one needs to be taken off to check it well.

As far as this vehicle being reliable. Yes they can be :SOMBRERO: But support from the dealers is not too good because of the small number they sold here in the US. So unless you possess some mechanical skills I'm affraid you may have picked the wrong vehicle your situation :roll:

There's a lot of knowledge here but if your depending on a dealer for service well.....

I would check for air too. There is a bleed valve in the filter head that can be opened while you push the pump. If you buy a filter, don't let them charge you over $100. They have tried to do this to me both times because the filter will come with the WHOLE metal filter head. The actual filter is $20-$40. I would start there. My Jeep went into limp mode one morning after a hard acceleration and it took until the next start to get it to go away. I was way over on my filter life. I changed it and it never happened again.

There is also a sensor on the airbox on the right front that has caused people problems. I guess if it gets lose, it can trigger limp mode. I think it has the mercedes logo on it.

I doubt it is the turbo (CAC) hoses if you said it doesn't sound loud. If it was the CAC then you would have tons of black smoke from what I understand as fuel doesn't get burned.

If it makes you feel any better I bought mine new and it was towed back to the dealer twice in the first week of ownership because it lost all electical power. I had less than 400 miles on it. I said I was going to give them my keys back and call it all off if it happened again, but I have had great fun ever since. 78000 miles later it has been pretty cheap to own. great as a daily driver and great in the winter.

Also quite possibly a clogging fuel filter. Your dealer's "solution" of simply throwing a mess of parts at it and praying the problem is fixed, however, does not bode well for his ability to fix it.

The problem is also very easily a fuel line fitting accidentally left loose, as they would have had to disconnect the fuel line to do some of that stuff. The morons from whom I bought mine (new) pulled that one on me. I drove it about a hundred miles before it did the no-power stunt, took it back, and they apologized after the tech stuck his head under the hood, said ohmygosh, and tightened the fitting. Worked great after that. Well, until a load of bad fuel clogged the fuel filter.

I should mention, 104,000 miles on mine now, and it is great in the winter.

Well here is the deal. I got it back to the dealer today and it was the fuel filter. After 4 hours of waiting they changed it and cleared some other codes. I pointed out to them that I had done some reading here, before I joined and said that if the EGR valve went out you should change the fuel filter too. They didn't and sure enough it went bad a week and about 300 mile later. So they replaced and said don't worry that is the only issues we ever have with these jeeps. Its all new, all codes cleared you will be in great shape. They did tell me the fuel filter needs to be changes every 20,000 and the it will be 133.00 dollars. In the end I drove the liberty home about 40+ miles and I kid you not the moment I turn on to me street the check engine light came on again. If I find another one I may be back to the forum, you guys have great information and are quick to respond and I appreciate it. But in my book this dealer has just taken their third strike and its going back. I may just have to settle for a car I don't want right now. But a car a don't want is better than a jeep that will leave me stranded, not meant to be a jeep rip, just my situation.

Thank all!

I had what sounds like the exact same issue. Ended up being the MAP sensor (blue sensor on intake manifold) being horribly dirty. Jeep had lost A TON of power, no boost, black smoke, etc. turned off, restarted fine... Later it did it again, same thing. turned off restarted ...fine... I have not had this issue repeat at all after cleaning this sensor. Hope this is it for you! Good luck!

I have found this vehicle very reliable. I think your style of driving will suit you very well, as I drive high miles similar to you. I'm pushing 150,000 miles and never had a breakdown or expensive repair to date. I have added a few mods, just to improve drivability and reliability, but nothing out of necessity. I've yet to replace the serpentine belt, but have a new one under the seat for luck. Sort out this problem and you should be good to go.

That's highway robbery! You can do it yourself in 15 minutes for about $35.

On your other issues, this CRD just may not be worth the hassle. Keep an eye out though, as there are always CRDs popping up on Autotrader, Cars.com, etc. Or you can look in our for sale section.... there are usually 2-3 CRDs in there for sale at any given time, most of which are in good working order and will come with complete service records and extra goodies :)

Have you done the timing belt? It was due at 100,000 miles.

Yep, I did the timing belt at 100k. I didn't think I could change that on the side of the road if it broke ;)

I still haven't solved my power loss problem either, but I think I'm getting closer to the answer - Next thing to check is the manifold's EGR tube, I think I can hear air escaping and I know it isn't boosted intake.

Just today, at 60mph cruise on a slight uphill... 7-8 psi boost, and 1400 degrees on my EGT probe in the turbo's inlet? That is a little excessive on the heat, and a LOT weak on the boost for that much heat.

As for these vehicles overall... Ya gotta be ready for surprises. Just getting home last night and checking my mail (community mailboxes) I smelled diesel. Just as I'm wondering where it is coming from... Engine quits. Hoo boy, what now? Next thing I hear is splashing from the rear end, onto the ground as the ASD relay (where I tapped for my pump) hadn't shut off yet. Stupid fuel pump had ejected itself from the OUTLET fuel line (of course) and had been dutifully pumping my $2.89 / gal diesel all over the ground. :banghead: :banghead: :banghead: :banghead:

I think I lost a good 2 gallons or so between where the trail started (while I was still driving in, amazingly) and where it quit finally.

Pushed it forward a few feet, nipped the end off the hose and re-tightened the clamps. Now I'm just waiting to see what is next for this thing to demand my attention.

I said it before - A supermodel girlfriend would be less work to maintain and keep happy.
