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 Envision are reminded to check the back seat if they opened the rear door before starting out. The Grand Cherokee doesn’t offer a back seat reminder.
The Envision’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Grand Cherokee.
The Envision (except Preferred) offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Grand Cherokee only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Envision and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available all wheel drive.
