Year by year: Flex against Yukon
The comparison that decides the purchase. A nameplate is not one car — a redesign can move the record sixty points inside two years, and the two nameplates rarely move together.
What owners actually complain about
Ford Flex
- Electrical System — 348 complaints
- Steering — 315 complaints
- Unknown Or Other — 220 complaints
GMC Yukon
- Engine — 569 complaints
- Power Train — 146 complaints
