Year by year: TLX against Q50
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
Acura TLX
- Power Train — 249 complaints
- Engine — 214 complaints
- Electrical System — 148 complaints
Infiniti Q50
- Steering — 119 complaints
- Electrical System — 86 complaints
