Methodology
Every verdict on this site is computed from NHTSA's public complaint, recall, and investigation data — never from sales figures, which aren't public, and never from raw cross-model comparisons, which are meaningless without knowing how many of each car were sold.
The five verdicts
- ▲ Better than typical
At least 30% fewer complaints than this model's typical year.
- ● Typical for this model
Within 30% of this model's typical year, either direction.
- ◆ Worse than typical
30% to 100% more complaints than typical.
- ■ Significantly worse — known issue year
More than double the complaints of this model's typical year.
- ○ Not enough data
Too few complaints on file, or too little history on this model, for a fair comparison.
The spike score
For a given model year, we compare its distinct complaint count to the median of that same model's other eligible years — median, not average, so one unusually loud or quiet year can't drag the baseline around. An "eligible" comparison year is one that independently clears the 30-complaint floor below; we require at least 5 eligible comparison years before computing a verdict at all, so a model with thin history isn't scored against a baseline built from noise.
We never show the raw ratio (e.g. "14× worse") on a page — only the discrete verdict label above. The number exists internally to rank years against each other (sibling-year strips, years-to-avoid ordering); showing it directly would invite exactly the kind of alarmist headline this site is built to avoid.
Severity weighting
Complaints flagged for a crash, fire, injury, or death nudge a borderline year's ratio up, capped at a maximum 15% boost. The cap is deliberate: a handful of severe-but-rare complaints can tip a close call, but can never manufacture a "significantly worse" verdict out of an otherwise flat year on their own.
Minimum sample size
Model years with fewer than 30 complaints on file don't get a verdict — we still show every complaint, recall, and investigation on file, just without a ranking that a tiny sample can't support.
Known problem areas
NHTSA leaves a meaningful share of complaints uncategorized ("unknown or other" and similar catch-all values). We exclude those from the ranked component list entirely — they're an absence of categorization, not a finding, and shouldn't occupy a "top problem" slot. Displayed percentages stay the share of this vehicle's total complaint count, not rebased over just the named components, so a year with heavy miscategorization doesn't show inflated percentages for the components that do have a name.
What we don't do
- We never use language like "will fail," "lemon," or "death trap." Severity badges come only from NHTSA's own crash/fire/injury/death flags.
- We never scrape CarComplaints, Consumer Reports, or J.D. Power. Every number here traces back to a public NHTSA source row.
- Complaints are unverified owner reports filed with NHTSA — not independently confirmed defects.
