Buick vs Lexus: The Verdict
A clear edge goes to the Japanese luxury brand, though not a landslide. Owners file fewer complaints per 1,000 cars sold (0.5 against 0.7), and both complaint severity and repair costs favor Lexus. Recall impact is even, even though Lexus has the larger recall count. Buick does better at spreading its problems across systems, but electrical and power train complaints still lead its list.
Lexus complaints cluster around air bags and electrical faults. Buick's trend is improving, while Lexus holds steady at a higher standing.

Who Should Buy Buick vs Lexus?
If you want the lowest chance of trouble, lean Lexus. Target the RX, the strongest SUV in either lineup, and look at 2022 first. The ES and IS are the sedan picks. Be careful with the NX: 2021 is the year to pick, and 2024 draws far more complaints than any other year.
Lean Buick if you want a good-rated vehicle and a lower entry point. Estimated repairs run from $466 to $573 a year across its models. The Encore and Envista lead the lineup, and the 2020 Regal is the sedan year to favor. Before you buy an Encore, ask about turbocharger work and air bag complaints, since owners report front air bags that did not deploy. On a Regal, test the stop-start system and watch for a false "Shift to Park" message that can drain the battery.
The Bottom Line: Buick or Lexus?
Pick Lexus if reliability is the priority, and make the RX your first stop, since it is the strongest single model across both lineups. Pick Buick if budget matters more, and plan on an average of $543 a year in estimated repairs. Lexus is rated cheaper to repair, but the data gives no dollar figure for it, so get quotes on the exact car.
