The 3.5L J35A5 V6 engine in the 2005 MDX is generally reliable when properly maintained, though it has some known issues. The engine itself is robust and can easily exceed 200,000 miles with regular oil changes every 5,000 miles and timely timing belt replacement every 90,000 miles. However, the timing belt tensioner can fail prematurely, making early replacement crucial. The VTEC system is generally trouble-free, but oil consumption can increase with age. Regular maintenance of the cooling system and using the correct grade of oil are essential for longevity. Overall, it’s a dependable engine that responds well to proper care.
