What the official records show
For the 2015 Hyundai Sonata, the NHTSA complaint API returned 1,139 unique owner complaint records across the catalog variants SONATA when Car Trouble Lab captured this dataset. Those records included 34 reports marked as involving a crash and 48 marked as involving a fire. Injury and death fields summed to 32 injuries and 2 deaths. The NHTSA recalls API returned 9 distinct safety campaigns, including 14V325000, 14V368000, 14V784000, and 15V414000. The captured component evidence profile was ENGINE: 618 tags (54% of unique complaint records), 4 crash-marked, 35 fire-marked, and 10 reported injuries; ELECTRICAL SYSTEM: 167 tags (15% of unique complaint records), 3 crash-marked, 16 fire-marked, and 7 reported injuries; POWER TRAIN: 133 tags (12% of unique complaint records), 1 crash-marked, 0 fire-marked, and 2 reported injuries; SERVICE BRAKES: 76 tags (7% of unique complaint records), 11 crash-marked, 5 fire-marked, and 7 reported injuries; FUEL/PROPULSION SYSTEM: 74 tags (6% of unique complaint records), 3 crash-marked, 5 fire-marked, and 4 reported injuries. The campaign evidence profile was 14V325000 (STEERING; received 12/06/2014; park-it flag); 14V368000 (SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER; received 24/06/2014; park-it flag); 14V784000 (POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT; received 09/12/2014); 15V414000 (SEAT BELTS:FRONT:BUCKLE ASSEMBLY; received 30/06/2015); 15V678000 (ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; received 20/10/2015). 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 ENGINE (618), ELECTRICAL SYSTEM (167), POWER TRAIN (133), SERVICE BRAKES (76), and FUEL/PROPULSION SYSTEM (74). Adjacent captured model years reported 2016: 718 complaints and 6 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 2015 Hyundai Sonata 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.
