If you're hunting for a used hatchback, you've likely come across the 2014 kia soul engine 2.0 l 4 cylinder, which was a pretty big step up from the base model that year. When Kia redesigned the Soul for 2014, they wanted to move away from the "cheap car" reputation and offer something that actually felt a bit more premium. While the base 1.6-liter engine was okay for getting groceries, the 2.0-liter "Nu" engine was the one most people actually wanted if they planned on hitting the highway or carrying more than a backpack.
It's a quirky little car, often described as a toaster on wheels, but that 2.0-liter engine gives it a lot more personality than you'd expect. However, buying one today isn't just about the horsepower numbers—it's about knowing what you're getting into mechanically, especially since these engines have a bit of a "reputation" in the used car world.
What Makes the 2.0L Different?
Back in 2014, if you stepped up to the Plus (+) or Exclaim (!) trim levels, you got the 2.0-liter engine as standard. This wasn't just a bored-out version of the base engine; it was a completely different design from Kia's "Nu" engine family. The biggest change was the move to Gasoline Direct Injection (GDI).
GDI was a big deal at the time because it allowed Kia to squeeze more power and better fuel efficiency out of a relatively small package. In the 2014 Soul, this engine pumps out about 164 horsepower and 151 lb-ft of torque. It might not sound like a race car, but in a car this size, it makes a massive difference. When you're trying to merge onto a fast-moving interstate, you'll definitely appreciate those extra horses compared to the 130 hp found in the base 1.6-liter.
The engine was paired mostly with a six-speed automatic transmission. It's a smooth combo for city driving, though it can get a little buzzy if you're really pushing it up a steep hill.
Real-World Performance and Fuel Economy
Driving the 2014 kia soul engine 2.0 l 4 cylinder feels surprisingly peppy. Because the Soul has that boxy shape, it's not exactly aerodynamic, so it needs that extra grunt to move through the air. The throttle response is sharp—sometimes almost too sharp—making it feel quick off the line.
As for fuel economy, it's a bit of a mixed bag. You'd expect a small 4-cylinder to get amazing mileage, but the boxy design works against it. You're looking at roughly 23 mpg in the city and 31 mpg on the highway. In the real world, most owners report averaging somewhere in the mid-20s. It's not terrible, but it's definitely not a Prius. If you're heavy-footed, you'll see those numbers drop pretty quickly.
The Elephant in the Room: Reliability
We have to talk about the reliability of the 2014 kia soul engine 2.0 l 4 cylinder because it's been a hot topic for years. While many of these engines are still humming along at 150,000 miles, others haven't been so lucky.
The 2014 model year fell right into the middle of some significant engine troubles for Kia and Hyundai. The 2.0L Nu GDI engine has been known to suffer from issues like excessive oil consumption and, in worse cases, rod bearing failure. If you hear a "knocking" sound coming from the engine bay, that's usually a sign that things are about to get very expensive.
Kia did issue recalls and extended warranties for many of these engines. In fact, many 2014 Souls on the road today actually have a replacement engine that was installed under warranty. If you're looking at buying one, the first thing you should do is run the VIN to see if the engine has been replaced or if there are any open recalls.
Oil Consumption is Real
Even if the engine is running fine, you've got to keep a close eye on the oil. These GDI engines tend to "burn" oil more than older designs. It's not uncommon for a Soul with 80,000 miles to go through a quart of oil every 1,000 miles. If you don't check the dipstick regularly and the oil level gets too low, the engine will start to wear down fast. It's a simple maintenance thing, but a lot of people forget, and that's when the big problems start.
Maintenance Tips to Keep It Alive
If you already own one or you've found a clean used one, there are a few things you can do to make sure the 2014 kia soul engine 2.0 l 4 cylinder lasts as long as possible.
- Change the oil often: Forget the "10,000-mile" oil change intervals some manuals suggest. If you want this engine to last, change it every 3,000 to 5,000 miles using high-quality synthetic oil.
- Use a Top-Tier fuel or cleaner: Because it's a GDI engine, carbon buildup on the intake valves is a common issue. Using a fuel system cleaner (like Techron) every few thousand miles can help keep things clear.
- Listen for the "Tick": If the engine starts sounding like a sewing machine or develops a rhythmic tapping, get it checked out immediately. It could be carbon buildup, or it could be something more serious like a lifter or bearing issue.
- PCV Valve: This is a cheap part that often gets overlooked. A clogged PCV valve can actually make oil consumption worse. Replacing it every 30,000 miles is cheap insurance.
Is It Still Worth Buying?
You might be wondering if it's even worth looking at a car with the 2014 kia soul engine 2.0 l 4 cylinder given the potential issues. Honestly, it depends on the price and the history.
The Soul is an incredibly practical car. The interior is spacious, the visibility is great, and the tech—even for 2014—is pretty decent. If you find one where the owner has documented every oil change, or better yet, one that has already had the engine replaced by a Kia dealership, it can be a fantastic value.
It's a car that punches above its weight in terms of utility. You can fold the seats down and fit a surprising amount of gear in the back. It's easy to park, and with the 2.0L engine, it doesn't feel like a golf cart when you're out on the open road.
The Verdict
The 2014 kia soul engine 2.0 l 4 cylinder is the heart of what made the second-generation Soul so popular. It turned a slow, entry-level car into something that was actually fun to drive and capable of handling a road trip. Yes, it has some known flaws, and you definitely shouldn't buy one without checking the service history.
But if you're a proactive owner who doesn't mind checking the oil every few weeks, the 2.0L Soul is a charming, practical, and zippy little ride. Just do your homework first. Look for the signs of well-maintained machinery, and don't be afraid to walk away if the engine sounds a little too "chatty" during a cold start. When it's running right, it's one of the best bangs for your buck in the used car market.
