Hello everyone! Newbie here. I have a 2011 4x4 jeep patriot latitude but I'm kind of disappointed in the lack of power. It feels sluggish when I take off & it almost feels like it's skipping/ jumping to the next gear while driving. It feels like it has no power, no umph. I took it to a mechanic & they told me it was due to the 4x4 gear being in the back & heavy.
I have zero knowledge of cars, but that sounded like a line of bs to me.
Anyways, I'm looking to do some mods on it but I don't want to spend a bunch of money modifying it if there's something wrong with my jeep.
I love my jeep but I'm worried I made a bad choice.
Any help would be much appreciated!

It isn't because the gear in back is heavy. Its because you have CVT transmission 165hp trying to move 3500lbs. Sadly these vehicle are slow, there isn't much that can be done. K&N intake helps a bit but ultimately its just not a rocket.

First off, welcome to the site! Stop by the Newbie check-in and greet the others.

You didn't say which engine you have. If you have the 2.0 its a pretty modest powerplant for a fair-sized vehicle with a substantial drive train. Jeeps aren't meant for racing. That bog-down feeling you get is the tranny heading for a higher ratio in interest of fuel economy, designed to be one of the Patriot's many strong points.

We have 2 Patriots, a 2.0 with the 5-spd and it spends a lot of time in lower gears on hilly terrain.
The other is a 2.4 CVT that's a bit spunkier, but both our Patriots are FWD so we're not hauling around the same drive train you are.

Presuming you have the CVT, if you re-flash your ECM it will learn your driving style in a few hundred miles, so if you drive it aggressively it may be more responsive, however, your fuel economy may suffer. Still, Tyler above has a point: 170hp going through a slush-box will never be snappy, and a 2.0 going through anything will be working pretty hard most of the time . . . especially if you're aggressive.

Again, if acceleration is important to you, re-flash the ECM. There are threads about that -- use the search box at the right end of the green stripe above.

Awesome! That helps me understand it a little bit better so thank you! I'm not exactly looking to race around, I guess I just assumed it would have a little more power behind it. I think my first step will be to re-flash the ECM to see if that helps. I'll have to check again to see if I have the 2.0 or 2.4. But I'm pretty sure I have the 2.4.

The easiest way to tell, but not perfect, is if you have an engine cover its probably a 2.4. If you're looking right at your coil-packs, then its the 2.0.

Or you can tell by your VIN, the 8th digit denotes the engine.
W = 2.4
Y = 2.0CRD
O = 2.0

A further note on that sluggishness, after the initial zip in the low ratios there is a significant drop in RPMs once you're up to about 25-30MPH. That is normal for a Patriot w/ the CVT. That's the ECM moving the tranny to a higher ratio for better fuel economy. That dip in the RPMs feels almost like a plugged cat-con -- you think you're going to blast off, but it seems to die. Again, that is normal for the CVT. As I said you may be able to get around that with a re-flash, but I haven't tried it myself.

You might get around that drop if you really press the pedal to the metal, but that's not something I ever do. I'm not quite a hyper-miler, but I treasure my fuel economy so my Patriot has only done maybe a dozen full-throttle accelerations in its life. About the only ones I pass are farm equipment, cement mixers, or seniors. :D
