Experts at TheCarConnection.com are starkly underwhelmed by the amount of interior space in the 2009 Jeep Grand Cherokee. Additionally, materials quality could be better overall.
Kelley Blue Book reports that the "Jeep Grand Cherokee can accommodate four adults in comfort—five in a pinch." About the front, ConsumerGuide warns that "headroom is not generous for six-footers, but there's ample legroom and shoulder space on supportive seats." In back, Kelley Blue Book explains that there is also "noticeable improvement in rear-seat legroom as well as ease of entry and exit, thanks to the longer rear doors"—a plus for passengers who do not like their knees meeting their ears. They complain, however, that the Grand Cherokee Jeep "does not offer a third row seat, and interior space is nowhere near the levels of larger SUVs." ConsumerGuide notes of the rear seating: it's "quite firm and not contoured for best comfort," adding that "three adults fit, but none have much foot space."
Edmunds confirms that "cargo capacity is low for this class, with just 35 cubic feet behind the rear seat and 69 with the seats folded.” ConsumerGuide says cargo space is "ample by absolute standards but subpar for the class."
Quality of the materials and switchgear inside the 2009 Jeep Grand Cherokee is an issue, too. Car and Driver terms the 2009 Jeep changes to the interior only "a start," calling the interior hard plastic "a merciless prison." The real wood used in the Overland trim level, however, does raise the bar. Jalopnik notes that "door panels have new armrests for improved ergonomics and comfort," and Kelley Blue Book praises the interior: "quality materials abound and the layout, execution and attention to detail are all first-rate."
Noise is well controlled in the 2009 Jeep Grand Cherokee. ConsumerGuide says that "one test 5.7 V8 AWD Limited suffered modest gear whine at highway speeds," while the 2009 Jeep diesel "makes a slight clattering noise at idle and during full-throttle acceleration," and "the SRT8 V8 provides a NASCAR-style soundtrack." The Grand Cherokee Jeep is rated by Car and Driver as "the quietest" compared to a HUMMER H3, Toyota FJ Cruiser, and Nissan Xterra when cruising on the highway, but in off-road tests, "its steel unibody sometimes emitted painful gronks when twisted."
