Replying to: ranch (Jul 17, 2007 5:06 pm) ranch: welcome to the Compass forum. We live on a steep dirt and gravel road. We are on atleast a 30 to 35% grade, and we have never had that happen....so far. We have 7.500 miles on our Compass and it is the 4x4. Maybe there is a fuel pump problem? How many miles have you on your Compass?    These Compass's have a good record so far, so maybe your dealer is not to sharp? Any other information would be helpful and might just jog someones idea bank.   farout Replies to this message: ranch (Jul 24, 2007 9:59 am) farout (Jul 25, 2007 12:21 pm) colloquor (Jul 27, 2007 4:51 am) and 1 more...

Replying to: ranch (Jul 17, 2007 5:06 pm) Howdy! I've got a little over 21k miles and never experienced a power loss on a steep climb >20 deg. (and I've been on several, some at elevations higher than 10k feet) If I had to guess it might be a transmission fluid level problem??? If low, maybe it runs out and by shifting from D to N and back allows the level to "re-prime" and then runs out again after a little bumping along. I think the trans is sealed (we owners can't easily check the level)It is just a guess, so take it with a grain of salt. By the way, the L gear is a pseudo-gear. All it really does it set the RPMs higher for any given speed (since this is a continuously variable trans, it really doesn't have set/defined gears). You can see this by shifting to L at any speed. If your RPMs were about 2500, at any given speed, it should jump to a little over 4000. It will do this at 25 MPH or 60 MPH. It is primarily to keep the engine in the power band while climbing (keeps it from possible lugging) or to provide engine braking on a downhill segment.   My only complaint, thus far, is an odd vibration from the engine in the 2200 to 2500 RPM range. You can feel it in the seat of your pants. It matters not if you're driving or sitting in park. When you raise the RPMs, either sitting in neutral or under gentle acceleration, it shakes from 2200 until about 2500 RPM. Under heavy acceleration it passes the revs up pretty quickly and you don't notice. I still plan on having the dealer check it out before warranty expiration. Performace is fine, just a little shake that I suppose might be a throttle position sensor or a computer tweak that might be needed. I am curious if anyone else has experienced this phenomena.   I hope you hold the dealer's feet to the fire on this. Loss of power can be a rather hazardous situation. Maybe a trip to the hills with a dealer rep onboard would convince them?   Keep us posted! Good luck!

Replying to: farout (Jul 17, 2007 5:41 pm) The compass has almost 5,000 miles, but has had the problem since it was brand new. The dealer is going to give me an on board scanner that will record the problem. Hopefully they will be able to figure it out. If they can't figure out the problem after that. They said that they would have the vehicle buy back process. Other than this problem the compass has been a very good vehicle. Thank you for your response. It's helpful to know that not every compass does this. Replies to this message: farout (Jul 25, 2007 12:21 pm) colloquor (Jul 27, 2007 4:51 am) farout (Jul 28, 2007 3:48 pm)

Replying to: ranch (Jul 24, 2007 9:59 am) ranch: The 2.4 engine is no award winner, and the initial flooring response is more of what I would expect from a 1.8 l Caliber. This world engine needs refinement, in fuel mileage, and power. I would expect with the "PILOT" (on board scanner) this will find an answer to your problem.    The MOPAR magazine had a three page article on the World Engine and this engine is a seriously complicated engine. There are two thermostats and it goes more complecated from that. This is not an engine to do some work on yourself, except oil changes.     I would guess that unless Chrysler gets some more real world horse power and better fuel mileage, this won't be one of Chrysler's better ideas. I personally hope this engine lasts as good as our 1996 Dodge Neon 2.L engine with 195,000 miles and still runs good.   farout Replies to this message: colloquor (Jul 27, 2007 4:51 am) farout (Jul 28, 2007 3:48 pm)

Replying to: farout (Jul 25, 2007 12:21 pm) What's interesting is the difference between the consortium "World Engine" 2.4L DOHC, and the Hyundai-specific 2.4L DOHC, which is different. I have a friend who owns a 2006 Hyundai Sonata with the 2.4L DOHC "Theta" engine, and it's smooth as silk at all rev ranges. It is my understanding that DCX made some changes to Hyundai's original 2.4L design in an effort to reduce production costs. However, I don't have a confirmation of this.

Replying to: colloquor (Jul 27, 2007 4:51 am) colloquor: The block is the Hyundai design and the top hals is a DCX design, with MB doing the majority of the work from a design they already had. The engine is very smooth when you drive it reasonably. Put punch it the enging sure sounds like you just unleashed a huge engine.    The 2.4 has plenty of get up and go at speeds above 40 mph, but low speed take off is much to be desired, fuel mpg is nothing to brag about, but taking 3,200 pounds around all the time is no small chore for the 2.4 either.    I have no idea if the same exact engine is put any other vehicle except Chrysler vehicles or not.   farout farout
#31 of 87 MPG's by jl49 Sep 24, 2007 (10:40 am)
I bought a Compass a month ago and I like it, but my only complaint is the gas mileage. I'm getting around 14 to 15 mpg's which is not the 23 to 26 mpg's advertised on the window sticker. Anyone have any suggestions? Replies to this message: farout (Sep 28, 2007 8:25 am) ranch (Sep 28, 2007 9:04 am)

Replying to: jl49 (Sep 24, 2007 10:40 am) jl49: We bought a Compass on April 3, 07. the average mpg was 22. We did get one trip that got 24 mpg. that was the one and only time in 10,200 miles. We had the so called 4x4, which is really an AWD. Our experience was less than we expected! The cheap plastic all over inside is not up to other brands standards. The power of the 2.4 engine was gutless!    We traded it in on a Chrysler Pacifica Touring AWD. We get 24.3 mpg on the highway and 22 around our home area. That's much better than the Compass.    I think unless Jeep makes some drastic improvements real fast the Compass is short lived at best.     I think the fuel mpg you are getting should be better, but don't you will see the 26 that the Jeep sticker says.   farout Replies to this message: ranch (Sep 28, 2007 9:04 am)

Replying to: farout (Sep 28, 2007 8:25 am) I no longer have my compass. I traded it in for a 4x4 Chevy TrailBlazer. The dealer in a round about way told me that the variable drive transmittion will not work at low speeds on steep dirt roads. The vehicle we have now does the job just fine.
