What the official records show
For the 2018 Jeep Grand Cherokee, the NHTSA complaint API returned 847 unique owner complaint records across the catalog variants GRAND CHEROKEE when Car Trouble Lab captured this dataset. Those records included 42 reports marked as involving a crash and 10 marked as involving a fire. Injury and death fields summed to 33 injuries and 0 deaths. The NHTSA recalls API returned 11 distinct safety campaigns, including 18E097000, 18V048000, 18V280000, and 18V332000. The captured component evidence profile was ELECTRICAL SYSTEM: 337 tags (40% of unique complaint records), 5 crash-marked, 6 fire-marked, and 3 reported injuries; ENGINE: 121 tags (14% of unique complaint records), 6 crash-marked, 3 fire-marked, and 0 reported injuries; POWER TRAIN: 72 tags (9% of unique complaint records), 7 crash-marked, 1 fire-marked, and 2 reported injuries; SERVICE BRAKES: 62 tags (7% of unique complaint records), 10 crash-marked, 0 fire-marked, and 4 reported injuries; FUEL/PROPULSION SYSTEM: 44 tags (5% of unique complaint records), 4 crash-marked, 1 fire-marked, and 2 reported injuries. The campaign evidence profile was 18E097000 (EQUIPMENT:ACCESSORY:FLOOR MAT; received 29/10/2018); 18V048000 (FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS; received 11/01/2018); 18V280000 (POWER TRAIN:AUTOMATIC TRANSMISSION; received 01/05/2018); 18V332000 (ELECTRICAL SYSTEM:WIRING; received 17/05/2018); 18V524000 (ELECTRICAL SYSTEM:WIRING:FRONT UNDERHOOD; received 09/08/2018). 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 (337), ENGINE (121), POWER TRAIN (72), SERVICE BRAKES (62), and FUEL/PROPULSION SYSTEM (44). Adjacent captured model years reported 2017: 364 complaints and 6 campaigns; 2019: 362 complaints and 7 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 2018 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.
