Wow, super upgrades, incredible ride!
By dc Zman on 5/18/2025 12:49:33 PM
OK, so I have owned 2 previous suburbans (2002 & 2013), so the 25 is an amazing upgrade to both of these! First of all, we do a lot of highway miles and the ride is simply amazing! It rides more like a luxury sedan than a truck. Since this is our primary vacation vehicle, we were careful to order 18 inch wheels, as they have a much smoother ride versus the larger ones. I also love all of the new cameras, which is a big help in tight situations. Also, the adaptive cruise control and lane assist make long road trips easier and safer as well. I also love the new exterior design features, particularly the front grill and the aerodynamic wings on either side of the rear window. I'm a bit surprised that those small design features have really updated and enhanced the look so much. The only real disappointment, so far, is the owners manual was really poorly done. Information is difficult to find, nonexistent and they even neglected to put in the required scheduled maintenance requirements (what were they thinking?). Overall, our first impressions on this vehicle have been superb and I would definitely recommend it to others who need a large family/vacation vehicle! - 5.0
Love it
