What the official records show
For the 2012 Jeep Grand Cherokee, the NHTSA complaint API returned 1,638 unique owner complaint records across the catalog variants GRAND CHEROKEE when Car Trouble Lab captured this dataset. Those records included 46 reports marked as involving a crash and 104 marked as involving a fire. Injury and death fields summed to 35 injuries and 0 deaths. The NHTSA recalls API returned 11 distinct safety campaigns, including 11V487000, 14V104000, 14V154000, and 14V391000. The captured component evidence profile was ELECTRICAL SYSTEM: 834 tags (51% of unique complaint records), 5 crash-marked, 94 fire-marked, and 3 reported injuries; SERVICE BRAKES: 288 tags (18% of unique complaint records), 21 crash-marked, 2 fire-marked, and 10 reported injuries; ENGINE: 284 tags (17% of unique complaint records), 4 crash-marked, 17 fire-marked, and 1 reported injuries; FUEL/PROPULSION SYSTEM: 215 tags (13% of unique complaint records), 4 crash-marked, 1 fire-marked, and 2 reported injuries; POWER TRAIN: 101 tags (6% of unique complaint records), 4 crash-marked, 2 fire-marked, and 0 reported injuries. The campaign evidence profile was 11V487000 (ENGINE AND ENGINE COOLING; received 29/09/2011); 14V104000 (SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP; received 04/03/2014); 14V154000 (SERVICE BRAKES; received 01/04/2014); 14V391000 (ELECTRICAL SYSTEM:WIRING; received 02/07/2014); 14V634000 (ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR; received 08/10/2014). These are reported-record counts, not a measured failure rate and not a diagnosis of any individual vehicle.

How to interpret the pattern
The most frequently assigned complaint component categories in this captured query were ELECTRICAL SYSTEM (834), SERVICE BRAKES (288), ENGINE (284), FUEL/PROPULSION SYSTEM (215), and POWER TRAIN (101). Adjacent captured model years reported 2011: 1,638 complaints and 6 campaigns; 2013: 802 complaints and 10 campaigns. These comparisons are raw record totals, not exposure-adjusted rates. One complaint can carry more than one component tag, so category counts should not be added to reproduce the total complaint count. Too few usable positive mileage values were present to publish a median. NHTSA complaint records are owner-submitted and may be incomplete, duplicated before ODI-number deduplication, or unverified. A high count can also reflect how many vehicles were sold and how long they have been on the road. Use this page to choose inspection questions, not to label every 2012 Jeep Grand Cherokee defective.
methodology
What to check next
Start with the categories that repeat most often, then compare the complaint description and warning symptoms with the actual vehicle rather than ordering a part from a category label. Check the full 17-character VIN in NHTSA's official recall lookup because a model-year campaign list cannot tell whether a particular vehicle is included or whether its remedy was completed. Preserve diagnostic trouble codes and freeze-frame data before clearing them, ask for repair invoices, and obtain a qualified inspection when a symptom affects braking, steering, restraint systems, fire risk, or drivability. Car Trouble Lab does not determine whether a vehicle is safe to drive.
