GarageCalc What the data says
Air bags accounts for about 22% of this year's Chevrolet Impala complaints. Complaints are spread across several areas, which reads more like normal ownership noise than a single defect.
The 2014 model year contributes 6 complaints (15%). Older vehicles dominate, consistent with age-related wear rather than a new defect.
Complaints are down year over year, 50 to 41 (-18%), while the market overall rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Chevrolet Impalas are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
