Every Impala model year from 2004 to 2020, scored on reported failures weighted against how many were sold — and ranked against every other Mid-Size Passenger Car of the same year.
Across 17 scored model years the Impala needs fixing less often than its class, and repairs cost about what you would expect. The spread between years is what matters: 2018 is its strongest, 2014 its weakest.
Longer bar is better. Rank is against every Mid-Size Passenger Car sold that same model year.

The line held a middling position through 2015, then moved to strong from 2016 on. This 2020 car falls in a strong stretch.
All 12 systems, measured against the class average for each model year.
Every Impala model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Mid-Size Passenger Car of the same year, so a common failure is judged against how common it is everywhere else.
Across the last three model years (2018–2020), no single system stands out. All measured systems draw issue reports less often than the same systems on the average Mid-Size Passenger Car of their year — a cleaner sheet than most of this class manages.
All 38 Mid-Size Passenger Cars from 2020, plotted by how often they need fixes and what those fixes cost.
2018 is the strongest Impala model year on record, ranking #6 of 43 Mid-Size Passenger Cars that year.
2014 is the weakest year in the model's history, ranking #41 of 48.
The 2020 Impala ranks #8 of 38 Mid-Size Passenger Cars — the upper quarter of its class.
Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.
