Hyundai Ioniq

Where it stands out against its peers

• Electrical system: more complaints than 98% of 2017 cars — 42% of its 50 complaints, where an ordinary 2017 car has 17%.
• Hybrid propulsion system: more complaints than 99% of 2017 cars — 14% of its 50 complaints, where an ordinary 2017 car has 0%.
• Vehicle speed control: more complaints than 90% of 2017 cars — 10% of its 50 complaints, where an ordinary 2017 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.

Crash test
