Mercedes-Benz GLK350 AC compressor failure after 5 years requiring expensive replacement on Mercedes-Benz GLK350

Some Mercedes-Benz GLK350 owners report experiencing AC compressor failure after about 5 years, which can lead to costly repairs. This issue is commonly attributed to refrigerant leaks, electrical climate control problems, or direct issues with the air conditioning compressor. In cases where fault codes indicate a short in the compressor, replacing it may be the only solution. Additionally, if the compressor seizes, the controller may detect excessive load on the engine and cut off the command, potentially causing further damage to other AC components. When the AC compressor malfunctions, owners often find it either damaged internally or not spinning, necessitating a pressure check to evaluate its condition. Overall, these complications highlight the potential for expensive replacements due to the intricate nature of the GLK350's air conditioning system.
