In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Tahoe are reminded to check the back seat if they opened the rear door before starting out. The Grand Cherokee L doesn’t offer a back seat reminder.
The Tahoe has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Grand Cherokee L doesn’t offer front seat center airbags.
Both the Tahoe and the Grand Cherokee L have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

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:
Tahoe | Grand Cherokee L | |
Standard Alternator | 220 amps | 160 amps |
Optional Alternator | 250 amps | 180 amps |

For better ride, handling and brake cooling the Tahoe offers optional 22-inch wheels. The Grand Cherokee L’s largest wheels are only 21-inches.

The Grand Cherokee L doesn’t offer vehicle monitored tire inflation.
The Tahoe has a standard full size spare so a flat doesn’t interrupt your trip. A full size spare costs extra on the Grand Cherokee L. Without the option you must depend on a temporary spare, which limits mileage and speed before replacement.

The Grand Cherokee L’s standard rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.
The Tahoe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Grand Cherokee L’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.
