I remember Cadillac, back in the 80s, really made things complicated. After driving a '96 K1500 for six years, a '94 Z28 for a year-and-a-half, a '95 Z28 for six years, an '02 K1500 for seven years, and an '02 Z28 for six years, I've had no real trouble with anything electrical that I didn't cause, LOL! Everything I can think of related to electrical gremblins were a result of a fautly PCM programmer and headers burning through a wire harness. With everything going electronic, I'm sure they've got a lot of experience and expertise on their side
