Safety
Warranty
There are over 73 percent more Chevrolet dealers than there are GMC dealers, which makes it much easier should you ever need service under the Suburban’s warranty.
Reliability
The Suburban has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Yukon XL doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.
