买二手车之前，或者自己的车开始出怪毛病时，最有用的信息不是论坛上的个人经验，是同款同年份的几千条车主投诉集中在哪个部件、一般开到多少英里出现。 这里直接查 NHTSA 的公开接口：VIN 解码出真实配置、官方召回清单（含后果与处理方式）、以及全部车主投诉按部件聚类计数——排名、中位里程、是否涉及事故或起火，全部由代码统计，不经模型。 有一条必须说在前面：按车型查召回只能告诉你有哪些召回，要知道「这一台」修没修，必须用 VIN 去品牌官网或 NHTSA 查未完成召回。修召回是免费的，所以没修往往只是因为车主不知道。$2 解锁投诉原文聚类成的故障图谱、看车时该问卖家的针对性问题、该让技师重点查的部位，以及同款不同年款的优劣对比。Before buying used — or when your own car starts doing something odd — the useful signal isn't forum anecdotes. It's where thousands of owner complaints for the same model year concentrate, and at what mileage they appear. This queries NHTSA's public APIs directly: VIN decode for the real specification, the official recall list with consequences and remedies, and every owner complaint clustered by component — ranking, median mileage, and whether crashes or fires were involved, all counted in code. One thing up front: a model-level recall search tells you which recalls exist, not whether this particular car was fixed. For that you must check the VIN against the manufacturer or NHTSA for open recalls. Recall work is free, so "not done" usually just means the owner never knew. $2 unlocks a fault map built from the complaint texts, the questions to ask the seller, what to have a mechanic check, and how the model years compare.
投诉原文聚类成的故障图谱（部位 / 里程段 / 严重度）+ 看车时该问卖家的针对性问题（问法决定你能不能听出他在回避）+ 该让技师重点查的部位与检查方法 + 同款相邻年款的优劣对比。A fault map built from the complaint texts (component, mileage band, severity), targeted questions for the seller phrased so evasion is audible, the specific checks to ask a mechanic for, and how adjacent model years compare.
数据来自美国 NHTSA 的公开接口（VIN 解码、召回、车主投诉），主要覆盖美版车型，非美版可能查不到或不完整。车主投诉是未经核实的自述，数量受该车型保有量影响很大，不同车型之间比绝对数没有意义。召回按车型查只反映存在哪些召回，不代表某一台车的实际维修状态——请用 VIN 单独确认未完成召回。本工具不做车况评估、不构成购买建议，也不能替代实车检查与专业技师的判断。你填写的内容不入库。Data comes from NHTSA's public APIs (VIN decoding, recalls, owner complaints) and mainly covers US-market vehicles; others may be missing or incomplete. Complaints are unverified self-reports and their volume tracks how many of that model are on the road, so raw counts are not comparable across models. A model-level recall search shows which recalls exist, not whether a given car was repaired — check the VIN for open recalls. This is not a condition assessment or a purchase recommendation and does not replace an inspection by a qualified mechanic. Nothing you enter is stored.
