The 3.7-liter General Motors LLR engine was assembled at a plant in America from 2006 to 2012 and installed on GMT345 / 355 platform models such as the Chevrolet Colorado and Hummer H3. This inline 5-cylinder engine is distinguished by enviable reliability, but its consumption is high.

Disadvantages of the GM LLR engine
- This is a completely reliable and resource unit, but its consumption is not the smallest.
- At high mileage, valve seat wear and chain stretch are common.
- Many complaints are related to the low resource of the water pump and viscous fan coupling.
- It is important to monitor their condition, as aluminum motors do not tolerate overheating.
- And here the rear crankshaft oil seal often flows and the exhaust manifold bursts.
