The Tahoe 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 Grand Cherokee L doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.
To reliably power the ignition and other systems and to recharge the battery, the Tahoe has larger alternators than the Grand Cherokee L:
