Is the 2017 Buick LaCrosse reliable?

Overall reliability is often described as average to above average for a full-size sedan, with strong comfort and drivability, but some owners report transmission behavior and infotainment issues that can affect satisfaction.

What are the most common 2017 Buick LaCrosse problems?

The most commonly reported issues include 8-speed automatic shudder/rough shifting, infotainment freezing or Bluetooth problems, battery/stop-start or eAssist-related warnings (where equipped), and occasional suspension or brake noise/vibration as mileage rises.

Are maintenance costs high on a 2017 LaCrosse?

Routine costs are typically reasonable for the class (oil changes, brakes, tires), but repairs involving infotainment modules, sensors, AWD components, or hybrid/stop-start systems can raise ownership costs compared to simpler sedans.

What are the best years of the Buick LaCrosse to buy?

Many shoppers prefer later years of the third generation after early software updates and running changes, but a well-maintained 2017 can still be a great buy if it has service records and a clean test drive with no transmission shudder.

What should I check before buying a used 2017 Buick LaCrosse?

Test drive at low speeds and steady highway cruising for transmission shudder, verify every infotainment feature works without rebooting, scan for stored codes, confirm battery health, and inspect tires/brakes/suspension for uneven wear or clunks.
