We purchased a new 2018 Compass Trailhawk in Feb 2019. It has just over 3,000 miles and low oil pressure light came on. Stopped to check oil and no Oil. WOW, so pissed!!! One why did the low oil light not come on, Second I can only imagine the damage caused to the engine because of this and driving around with low oil. There is bound to be long term issues because of this. Called the dealer and can't get in for two weeks. Had to add 2.5 quarts of oil to a brand new car. Not only that but going over a speed bump @ 5mph you can hear and feel the right front bottom out and make a big clank. I have a sad feeling this is going to be one hell of a headache and probably the worst car I have ever purchased and I'm 55 years old. Anyone else having these issues.

Welcome Zildjian!

Yes, there are a couple threads on here about excessive oil consumption. My 2018 used a lot at first (1000/qt) but gradually improved to about 3000/qt by the time it got to 30,000 miles. So there is hope.

Any new engine will use some oil. After my 2018 Compass was wrecked I bought a 2019 Compass and the new one is much better on oil. I just added 1/2 quart at 3500 miles which I consider normal for a brand new engine. Typically the oil consumption should moderate after about 10,000 miles.

The party line is that 1000/qt is "normal," but I don't buy that. The reason is that to maximize fuel economy new engines are using thinner oil and the tolerances are looser to reduce internal friction. Putting those two thoughts together is a recipe for increases oil consumption.

We are not alone. I've heard these complaints from Honda owners and Ford owners. Seems I read that the new Mustangs can run 500/qt. That's outrageous, but that's how manufacturers are achieving the CAFE standards.

For my part, I'd adjusted to checking my oil every 1000 miles. Adding a quart or two between changes is a nuisance, but it isn't the end of the world either.

Only problem other then the added costs with this method are that you never really know how much you are adding.
Overfilling on a regular basis can lead to issue of its own and even gasket leaks.
I've checked mine once since new and still good on the dip stick but will closely monitor.
If you care about the car the best way is to do oil changes sooner then scheduled (which I do anyway but not by that much).
That sounds like REALLY excessive oil burning and maybe need a compression and leak down test to see if piston rings defective or something of that nature. Hope dealer helps investigate that doesn't sounds even remotely normal.

Why? Crosshatch on the dipstick corresponds to 1qt. You can calculate exactly how much you need to add based on that.

Just a note here, the oil light indicates low oil pressure, not low oil level. I have heard if the oil pressure drops too low (could be due to low oil level or other reasons, pump failure, leak, etc.) the engine will shut down as not to damage the engine. My 2018 was using oil when we first got it. It now has over 13K miles and on a 1300 mile all highway trip with temps in the 90s, it used less than a pint of oil. That's over 2600 miles/quart. And remember, these engines use super thin oil to get the gas mileage we do and that translates into more oil usage.

I think if you get a low oil pressure warning, it means you pretty much damaged the engine. Low oil pressure warning indicates the oil pump is sucking air, oil pump is at the bottom of the engine. If the oil level is that low to allow oil pump to such air, top of the engine is pretty much running dry.

This is why it is always a good practice to check you engine oil manually. Keep in mind damage resulting from low oil (even due to burning oil) is not covered by warranty because owner is responsible for maintaining proper fluid levels. Checking the oil once a week would not take more than 3-5 mins. You can even do it with the cold engine (even if manual suggests fully warmed engine). I just check the cold engine, if the oil level is on crosshatch with cold engine, it will be on crosshatch when warm. Just dont fill based on cold reading as you can overfill (cold will read about 1/3 - 1/4 qts lower than warmed).

Yeah it's a decent guess, but you don't know exactly and you have to make sure on level ground when checking dip stick.
It's a crude measure but you don't know the exact CC's without actually adding the correct amount when you change the oil.
Anyway, shouldn't happen on a new car, maybe if you have 300,000 kilometers this kind of practice is expected.

This is what happens when governments try to legislate physics. Congress or Parliament can pass all the laws they want but Mother Nature has a different set of laws that cannot not be superseded.

Our new model '17 Compass w/2.4L I4 MultiAir Engine uses about a quart every 2,500 miles. Dealer said it was a clogged PVC valve. They replaced, but still uses the same amount of oil. Threads on other forums say this is a common problem with this engine. I too blame it on the thin oil. I'd try a 5w20, but that would probably void the warranty. I'm 70 years old, and the only other vehicle I've ever owned that went through oil this fast was a 1970 Impala with a leaking main seal. Other than the oil problem, our Compass has been bullet proof for two years now. Since it's my wife's DD, and she only puts about 6,000 miles a year on it, I'll just keep checking it, and keep a quart on hand. First world problems!

We’re in the same boat, the wife maybe puts 6,000 miles a year. I’ve been extremely meticulous monitoring the oil level. Initially her compass was consuming 1qt/2,000 miles (oil/filter changed) then 1qt/2,500 miles (oil/filter changed) and now looks like less than 1qt/5,000 miles. She only has 150miles before reaching 10,000 miles on the OD. that seems to be a magical number for oil consumption slowing down, PROVIDED you catch it early and not letting the low oil light come on. hopefully it keeps improving over time. as a side note, her driving style was aggressive for the first 5k miles, lots of 4k-5k rpms launches and zipping around in traffic. She’s one of those drivers “who can get to the next red light the fastest” lol …

We bought a new 2018 Compass, had to have a new engine before 4500 miles were on the vehicle. Had to have a new engine installed because cylinders were scored. New engine consumes just as much oil. On top of that we a have a ton of electrical issues no one can explain. Had to have new sway bars in front because of thumping noise when we hit bumps and this Jeep only has 29,000 miles on it. Sounds like you have similar issues as we do. Document everything! Take pics of your dip stick, any messages that appear and keep your service records. We dealt with FCA for almost year and got nowhere, they’re a joke! But my caseworker referred me to another arbitration company, where I submitted documentation and pictures to a 3 person review board and we won our case. We just found out Monday that Jeep has to pay our existing loan and cover all the costs of getting us into a new vehicle. The whole process dealing with FCA and NCDS was tedious and time consuming but I felt it necessary considering I paid $28,000 for a vehicle that was junk before I drove it off the lot. Jeep knows this engine has oil consumption issues but will jerk you around with oil consumption tests until your warranty is up. Be persistent and keep all notes and receipts because this issue is not going to go away.

I think it is important to recognize whether something is actually a potential cause, or not. A 2018, I believe, uses 0W20, which is a very typical viscosity and has been used for many years by many manufacturers without issues. Another point is that some of these Jeeps use a lot of oil, while others don't, despite using the same oil. People keep saying the oil is 'too thin' but, objectively, there is strong evidence that the oil viscosity is NOT the problem. On the other hand, these being new vehicles and only some having this problem, it is logical to suspect there is a manufacturing issue affecting some of these vehicles and causing the oil loss (and it is FCA so that's practically a given).

I would just like to say thank you for your efforts. It's important to have at least some customers who do the work and hold the corporation to account. Sad to say but unless there is a public backlash and $$$ costs being incurred they aren't going to bother making changes.

You should NEVER have to check the oil in the car as often as everyone says you should or put a drop in it. A new car shouldn't burn oil period, perhaps a high milage car would but thats to be expected.. I don't care who makes it or the type of motor it is. I ran into the same problem on our 2018 Jeep Compass and had to ditch it. NCDS didn't do squat and FCA's warranty is useless. If your motor burns oil excessively its a design flaw and that falls on the manufacturer.

i've owned sky high mileage vehicles that retain oil at a better rate or don't burn it at all compared to this. I remember someone saying this 2.4L is the most technologically advanced motor of it's kind, it's also the most underpowered motor you can stick in these chassis.

Wasn't this the way you ruined your Compass'es engine? I remember yous saying you never put in oil and just waited for the low oil pressure to show. No wonder you run into extreme oil burning, while other who maintained their oil levels eventuality went to no to low oil burning range. What you say is a very bad advice lol. All modern small capacity high power engines have the capacity to burn oil due to narrow margins, especially when new. Worse thing you can do is ignoring the oil level and turning temporary problem into a permanent one. If you check Ford or BMW forums, you would see some get oil consumption around 1qt per 500 miles, which is far worse than what anyone gets with Compass. As unfortunate as this is, this is where the industry is going to.

I remember someone saying this 2.4L is the most technologically advanced motor of it's kind, it's also the most underpowered motor you can stick in these chassis.
Yeah it is, it is a type of engine where the bottom and the top of the engine is not linked mechanically but linked hydraulically. That is type of tech used in Ferrari engines, which makes sense since until recently FCA owned Ferrari. You say it is under-powered, but how many 4 cylinder, naturally aspirated engines below 2.5L you can name that makes more power than this engine? The only ones that come to my mind are exotic engines like Mazda's rotary engine and Honda S2000 engine that reved to something like 8500 RPM.

LOL.... no I didn't ruin it, the motor was already ruined from the factory. I didn't even make 3000 miles (BEFORE THE MILEAGE OR BEFORE THE DATE) before it ate all the available oil and did so 2-3 different times, I guess by your advice it's ok that a perfectly new car burns thru all it's available oil. It's well documented that the Multi Air 2.4L is an oil burning piece of garbage. The Compass isn't a 20 year oil Chevy with all the main seals bad on it, it's a new car.

My 20 year old 4.6L V8 Mustang doesn't burn a drop and it's over 100k miles and I beat the tar out of that car, this new 2019 Dodge RAM Hemi has 15k miles on it since we ditched the Compass and guess what? Not a single drop of oil burned. If your OK with this vehicles short comings I'd hate to see how you view a sub par dinner at a 5 star restaurant, but I'm sure you will say its fine, all food comes out burned is a "just deal with it" case, thats what your saying. If you have to check the fluid levels every week then you would be better off buying a beater with a heater.

So you didn't check oil once for 3000k miles for a new car. Cool lol. I guess you also didnt read what the owners manual suggest to do during engine break in.

i have not had any oil compsumption trouble with my compass, im now in my 4th oil change, 21k miles. If it had done this "almost all oil consumed" in the first 3k mile, i would of left it in the dealer till they fix it, or buy back.

Pretty obvious even if I did it won't have made a difference, it was a lemon from the get go. To pacify you, yes I read the manual when I had it.. It has the same jargin that other auto manufacturers put in there for the sake of legalities to not drive it like you stole it and check your fluids now and then, not every day, not every week and certainly not every time you drive it.

Here is a snippet:

ENGINE BREAK-IN RECOMMENDATIONS A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle.Drive moderately during the first 300 miles (500 km).After the initial 60 miles (100 km), speeds up to 50 or55 mph (80 or 90 km/h) are desirable.While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in.Wide-open throttle acceleration in low gear can be detrimental and should be avoided.THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 83 The engine oil installed in the engine at the factory is a high-quality energy conserving type lubricant. Oil changes should be consistent with anticipated climate conditions under which vehicle operations will occur. For the recommended viscosity and quality grades, refer to"Maintenance Procedures" in "Maintaining Your Vehicle".


NOTE: A new engine may consume some oil during its first few thousand miles (kilometers) of operation. This should be considered a normal part of the break-in and not interpreted as an indication of difficulty.

^^^

"Some" oil, some in my definition would be maybe a half a quart, quarter of a quart not 5-6 quarts and certainly not 15 quarts like mine did in 10k miles. It only ate more as the miles went up. The OP is saying before the first 3k miles it ate all his oil, mine did the same. I'm still waiting for you to say that's normal. :popcorn: Anyone will tell you that it's not. You don't have to change the oil per the manual for 5k mile intervals. The OP, myself, and many others never got to that interval with mileage or date.

When that low oil pressure indicator comes up it means shes dry (less than a quart) but of course FCA cannot account to where that oil goes, it magically disappears. The Compass is clearly a magician.
