Lexus GX460 EGR value failure issue with ongoing repairs and high costs on Lexus GX460

Some Lexus GX460 owners report experiencing issues related to EGR valve failure, including symptoms such as rough idling, reduced power and acceleration, increased fuel consumption, and the illumination of the Check Engine Light (CEL). These problems can arise due to the disintegration of the air injection pump's foam filter, which may block the secondary air injection system's valves and lines. Additionally, repair challenges can lead to significant costs, with expenses for fixing valve cover leaks into spark plugs reaching around $800 and EGR valve repairs starting from $623. Understanding these symptoms and the potential repair costs emphasizes the importance of timely diagnosis to prevent further damage.
