Very reliable mechanically. Electronics...not so much. Gets very expensive!

I had it from about 90k miles to 140k miles. You can't beat the interior comfort and ride quality. The engine performed flawlessly, as did the transmission. There was always a "growling" noise coming from somewhere in the transfer case. It was very annoying, but I never did anything about it other than change the differential fluids and trans/transfer case fluids. This did not make the noise go away. From time to time the "service ride control" message would appear...and then go away. The "service tire pressure monitor" message came on from time to time as well. I had to replace an abs wheel speed sensor at about 115k. Rear susp leveler compressor went bad. Front Heated seats broke.
Purchased the 2004 Caddy ESV in 2005 on a trade in of the 2002 Cadillac Escalade which was a lemon. The longer body style has improve for long hauling then the short body style. My 2004 Caddy does not have the DVD entertainment, but does have everything else i.e. navigation, satellite radio, CD player and a decent radio. Now that analog has become extinct OnStar and the other related emergency connections are useless. Vehicle has great "get up and go power!" Navigation CD is now outdated there is no new CD for the 2004 system to update, what a joke. Have not tried this vehicle off road, but in some of the heavy snow falls in the North East it out performed it self. It's just okay!
The vehicle has a lot of power. When it engages, it sets you back in the seat and lets you know but it does it gently, not like my previous 1999 Suburban with a 5.7L. More plush over bumps, on turns, and acceleration. The ammenities are overwhelming compared to a Suburban, and it feels like you got what you paid for.
