What the official records show
For the 2015 Chevrolet Tahoe, the NHTSA complaint API returned 661 unique owner complaint records across the catalog variants TAHOE when Car Trouble Lab captured this dataset. Those records included 30 reports marked as involving a crash and 2 marked as involving a fire. Injury and death fields summed to 18 injuries and 1 deaths. The NHTSA recalls API returned 14 distinct safety campaigns, including 14V152000, 14V246000, 14V301000, and 14V374000. The captured component evidence profile was SERVICE BRAKES: 199 tags (30% of unique complaint records), 17 crash-marked, 0 fire-marked, and 5 reported injuries; ELECTRICAL SYSTEM: 135 tags (20% of unique complaint records), 4 crash-marked, 1 fire-marked, and 4 reported injuries; STEERING: 70 tags (11% of unique complaint records), 3 crash-marked, 0 fire-marked, and 2 reported injuries; POWER TRAIN: 55 tags (8% of unique complaint records), 3 crash-marked, 1 fire-marked, and 1 reported injuries; EXTERIOR LIGHTING: 52 tags (8% of unique complaint records), 2 crash-marked, 0 fire-marked, and 1 reported injuries. The campaign evidence profile was 14V152000 (POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES; received 31/03/2014); 14V246000 (STEERING:LINKAGES:TIE ROD ASSEMBLY; received 14/05/2014; park-it flag); 14V301000 (ELECTRICAL SYSTEM:SOFTWARE; received 06/06/2014); 14V374000 (POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); received 27/06/2014); 14V451000 (AIR BAGS:SIDE/WINDOW; received 23/07/2014). 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 SERVICE BRAKES (199), ELECTRICAL SYSTEM (135), STEERING (70), POWER TRAIN (55), and EXTERIOR LIGHTING (52). Adjacent captured model years reported 2016: 256 complaints and 8 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 Chevrolet Tahoe 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.
