Detailed Explanations
2010: The 2010 GL350 Bluetec marked the introduction of the diesel engine to the GL-Class. As with many first-year models, it experienced some teething problems. Common issues included glow plug failures, AdBlue system malfunctions, and potential problems with the diesel particulate filter (DPF). These issues can be costly to repair, making a thorough inspection and review of the service history crucial before considering this model year.
2011: The 2011 GL350 Bluetec offered minor improvements over the 2010 model. However, it still shared the same engine and diesel emission system, meaning it was susceptible to similar problems. Specifically, issues with the AdBlue system, which is responsible for reducing emissions, remained a concern. A pre-purchase inspection is essential to identify any potential problems.
2012: The 2012 GL350 Bluetec saw some improvements to the diesel engine design, leading to slightly improved reliability compared to the earlier years. While still not without its potential issues, such as oil cooler leaks, it is generally considered a better option than the 2010 and 2011 models. However, a pre-purchase inspection by a qualified mechanic is still highly recommended.
2013: The 2013 GL350 marked a significant turning point with the introduction of the refreshed GL-Class (X166). This redesign brought about substantial improvements in technology, interior design, and overall ride quality. The engine was also refined, leading to increased reliability compared to the previous generation. This makes the 2013 GL350 a more desirable option for buyers seeking a balance of features and dependability.
2014: The 2014 GL350 continued the success of the X166 platform, offering similar features and improvements as the 2013 model. Known for its comfortable ride, luxurious interior, and reliable engine, the 2014 GL350 is considered an excellent choice. Minor updates and refinements further enhanced its appeal.
2015: The 2015 GL350 saw further refinements and updates to the X166 platform, solidifying its reputation for reliability. This model year is generally considered a top choice for buyers seeking a GL350 with modern features and dependable performance. Routine maintenance is still important to ensure its longevity, but major issues are less common.
2016: The 2016 GL350 marked the final year of the GL-Class before it was rebranded as the GLS. It offered minor updates compared to previous years but maintained the same overall reliability and features. If you prefer the GL-Class styling over the newer GLS, the 2016 model is a good option.
2017 (GLS350d): In 2017, the GL-Class was rebranded as the GLS-Class, and the diesel model was known as the GLS350d. While it continued to use the diesel engine, potential issues with the diesel particulate filter (DPF) became more prevalent in some markets, particularly in vehicles used primarily for short trips. The DPF is designed to trap soot, but it needs to regenerate regularly at higher temperatures. Short trips can prevent this process, leading to clogs and costly repairs.
