My 2005 GMC with 5.3 has nearly 170,000 miles. High oil consumption early on. My mechanic recommended synthetic and oil consumption stopped. Mechanic had other customers with same results. Been through three rear U joints. Front break assemblies with ABS and bearings replaced twice on each side. Misc electrical. PRNDL light burned out. Switch that turns light on when you enter no longer works. Very good truck. No major issues. I have changed tranny fluid twice. Oil every 5,000. I’d buy another 5.3 in a heartbeat.
