Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
In 2008 the 2008 Jeep Grand Cherokee recorded 733 complaints, 5 recalls and 0 investigations, placing its complaint volume between the 2007 total of 1,108 complaints and the 2009 total of 138 complaints. Recalls in 2008 (5) were comparable to the 7 reported in 2007 but higher than the 3 recorded in 2009, while investigations remained at zero like in 2009. The vehicle’s top complaint categories that year were Electrical System (340), Engine (41), Power Train (34) and a combined Electrical System,Engine count of 28, indicating that electrical and power‑train concerns dominated the feedback. Crash‑related complaints numbered 23 and fire‑related complaints numbered 5, both modest relative to the broader complaint count. Given that 2008 shows a noticeable drop in complaints from the preceding model‑year peak yet still higher than the low‑volume 2009 figures, the data does not point to a clear defect pattern, so the year is neither markedly unsafe nor exceptionally reliable, making it a cautiously acceptable choice for a used purchase.
All 733 complaints on record, top 8 components.
