In addition, GM’s other attempts to reduce noise from this engine include using a bed-plate engine block. Consequently, GM has claimed that their 1.0-liter SGE engine is 25% quieter than Ford’s similar 1.0-liter engine in the Fiesta. This can aid in reducing the vibrations and loud ticking sounds from the injectors. The direct injection fuel rails are mounted with bushings onto the cylinder head and valve cover. Hence, they all have the same 2.91-inch (74mm) bore, and 3.19-inch (81mm) bore spacing. A key aspect of the SGE Ecotec engine is its modularity, whereby components can be readily interchanged if needed. This encompasses their 3- and 4-cylinder versions. All of the aforementioned configurations (and many other unique or specialized variations of this) are made from just two engine blocks. Here are some of the most notable inclusions: GM SGE Engine Features To make it happen, GM has engineered an abundance of new and innovative technologies into their SGE collection of engines. This includes our culprit for GM 1.5 turbo engine problems: In particular, there are four distinct configurations that an SGE engine can be had with. Where, SGEs can be found on SAIC-made cars, too. On top of that, General Motors also sells this engine to their Chinese partner, SAIC Motors. GM’s SGE is also marketed as part of their ‘Ecotec’ (or in some other markets, ‘Microtec’) engines. In other words, GM’s smaller and cheaper vehicles. With all those characteristics in mind, GM succeeded in creating a lightweight, modestly powerful, fuel-efficient, low-emissions, and comforting engine to fit the smaller end of its stable. 
The latter stands for Noise, Vibrations, and Harshness, which defines the unpleasant or discomforting sounds and vibrations that you’ll experience while driving. Thus, their engine needed to also be decently performant, lower emissions, and reduce the NVH to a minimum.

Good MPG figures alone aren’t enough (once you’ve figured out how to calculate MPG).

At the turn of the 2010s, General Motors realized the design and built a new series of engines, made with efficiency in mind. So, what about this GM SGE engine family, then. Yet, despite the clever nature of these engines, could they also be badly flawed? Let’s take a peek at all the GM 1.5 turbo engine problems, and find out…īefore we get into the GM 1.5 turbo engine problems, some context might help. You can find these SGE motors inside of models by Buick, Opel, or GM’s China-only marque, Roewe. It was fitted into most of GM’s portfolio at the time. Or, the myriad of LS V8 swaps out there, even to puny cars like the MX-5 Miata.īy now, GM showed that they could make efficient, ingenious, but nonetheless potent powertrains. At the time, they were mostly known for big, gas-guzzling LS V8s fitted into muscle cars. This line-up of small-displacement motors, ranging from just 1.0-liter to a mere 1.5-liter, marks a huge leap forward for GM. Back in 2014, General Motors made a big splash with the appropriately named Small Gasoline Engine (SGE).
