For enhanced safety, the front and second-row seat shoulder belts of the Mercedes GLE have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Jeep Grand Cherokee L doesn’t offer pretensioners for its second-row seat belts.
The GLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Grand Cherokee L doesn’t offer pre-crash pretensioners.
The GLE offers optional Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee L doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLE has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Grand Cherokee L doesn’t offer a system that can receive automated systems from other vehicles.
Both the GLE and Grand Cherokee L have rear cross-traffic warning, but the GLE has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Grand Cherokee L’s Rear Cross Path Detection doesn’t automatically brake.
Both the GLE and the Grand Cherokee L have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mercedes GLE is safer than the Grand Cherokee L:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the GLE is 3% less likely to roll over than the Grand Cherokee L.
The Mercedes GLE (with optional crash prevention) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The Grand Cherokee L is not even a standard “Top Safety Pick” for 2025.
