Since its debut in 2019, the GM 2.7 turbo engine has courted controversy. Even as it packs a punch of torque and delivers a performance that seems to be far beyond its tiny size. There have been quite a few GM 2.7 turbo engine problems, too.
Though it was initially designed for trucks when launched in the Chevrolet Silverado 1500 and the GMC Sierra 1500, the engine soon began to be used in other vehicles, too. For instance, the Cadillac CT4, Chevrolet Colorado, and the GMC Canyon are some of the other GM vehicles that use this engine. A homegrown, made-in-America engine, the GM 2.7 can hold its own against the best in the world, though it’s prone to developing a few issues from time to time.
However, despite all the GM 2.7 turbo engine problems, it remains a popular choice for trucks and other car models, even in 2022. Let’s find out why.
What Makes GM 2.7 Turbo Engine An Amazing One Despite Its Many Problems
- Initially, the 4-cylinder engine provided 310 horsepower and 348 pounds of torque. However, the Chevy Silverado launched in 2022 has an updated version of the original turbocharged engine. The new turbocharger engine can produce over 420 pounds of torque at 1500 rpm.
- It’s the first 4-cylinder engine used in General Motors’ full-size pickup trucks.
- The GM 2.7 is a lightweight engine; it weighs just 80 pounds, which is way less than its competitors, like the 5.3L V8.
- It takes the engine just 1.93 seconds to achieve 90% of the peak torque at 1500 rpm.
- The boost the GM 2.7 turbo engine provides is enough to get onto the highway, merge and overtake the vehicles in front of you.
- It supports using your pickup truck to tow quite a few objects with approximately 9000-pound capacity.
After exploring what makes the GM 2.7 turbo engine so great, let’s look at some frequently recurring issues it can develop.
5 Most Common GM 2.7 Turbo Engine Problems
Even as we discuss GM 2.7 turbo engine problems, most experts estimate that these issues are probably overblown by competition to discredit the engine.
Let’s explore the 5 most common complaints one hears about in association with GM 2.7:
Poor Fuel Economy
Though the GM 2.7 turbo engine deploys the direct fuel injection system that boosts horsepower and is ideally supposed to reduce fuel consumption, the engine is known to be a fuel guzzler. While GM promised an average of 23 miles per gallon. Most customers report that the maximum mileage they can get is 19 miles per gallon. That is considerably lower than the Ford F150 2WD Diesel, which gives customers 25 miles for every gallon of gas.
So, it may not be the engine for you if fuel efficiency is high up there on your list. Otherwise, it’s not a deal breaker as far as GM 2.7 turbo engine problems go.
GM likes to boast of the engine’s higher horsepower despite its small size. Yet the older models are known for their low horsepower. At the same time, GM seems to have taken the feedback and upgraded the 2022 model to generate more energy.
Yet the previous cars and trucks continue to give owners trouble due to the lower-than-expected horsepower.
However, the engine continues to be in high demand despite the shortcomings related to fuel consumption and low energy generation.
Many complain that the engine is hard to find, a situation made worse by the COVID-linked chip shortage. However, this issue with the GM 2.7 turbo engine attests to its immense popularity.
Timing Belt Failure
One issue that does develop with a GM 2.7 a few years after owning the vehicle is timing belt failure. Now, a timing belt is a ribbed belt that keeps the top half of your engine in sync with the bottom half, and some have people reported that the timing belt starts to fail after a point and has to be repaired constantly.
We at Diesel Components Inc., have seen a few of these and know that you to perform a thorough turbo engine repair service to prevent it from happening again.
Once again, the company has worked out the GM 2.7 turbo engine problems with the timing belt and the timing chain in the 2022 Chevy Silverado.
Head Gasket Failure
Head gasket failure is another commonly reported problem with the GM 2.7 turbo engine across different vehicles.
The head gasket is the one that fits between the cylinder head and the GM 2.7’s 4 cylinders. It helps seal the combustion gases within the cylinders and even prevents coolant or engine oil leakage. Head gasket failure is why many GM customers complained about the expensive engine repairs they had to undertake due to issues with the engine heating and having to rebuild or replace entire engine parts.
How Does the GM 2.7 Turbo Engine Fare Against Other Engines?
As evident from the points above, the GM 2.7 turbo engine has its faults, yet it remains in high demand. One can spring for the upgraded model where GM has strived to overcome most of these problems. In the end, the GM 2.7 turbo engine is a small, compact mechanical marvel with a lot of heart.
