Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Grand Cherokee 4.7L.
The 2008 Jeep Grand Cherokee is a WK-platform SUV powered by a 4.7-liter engine paired with a 5-speed automatic transmission, requiring 6 quarts of 5W-30 or 5W-20 oil and delivering EPA-rated 14 city, 19 highway, and 15 combined mpg. With 733 owner complaints and 5 recalls, its top issue area is the electrical system, yet this model year sits well below the Grand Cherokee’s 2014 peak of 2,369 complaints, indicating a relatively moderate reliability standing within the nameplate’s long history.

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.
From the factory this vehicle uses a BCI 94R · 730 Early CCA battery, OE oil filter 04884899AC. Note the factory fuel filter and cabin air filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2008 Grand Cherokee sits at the low point of its generation's federal complaint trend, with 733 complaints — down from 1,108 in 2007 and 1,297 in 2006 — while recalls held at five and investigations dropped to zero. Electrical System issues dominate the 2008 record at 340 complaints, nearly half the total, though the data doesn't specify root causes for this concentration. Technical service bulletins also declined to 62 from 66 the prior year, suggesting diminishing factory-identified service patterns. The sharp drop to 138 complaints in 2009 likely reflects reduced fleet exposure rather than a design improvement, while the 2011 spike to 1,638 coincides with the next-generation launch. With the lowest complaint volume of the 2005–2010 platform run, no open investigations, and modest recall activity, the 2008 model year presents a comparatively clean federal record for a used purchase.
