GMC Sierra HD

Where it stands out against its peers

• Structure: more complaints than 94% of 2022 cars — 17% of its 1,188 complaints, where an ordinary 2022 car has 4%.

Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.
