Buick LaCrosse Road Test

Model Year Summary

The redesign of Buick's flagship rests on a new structure that resulted in a weight reduction of 300 pounds and improved visibility. Buick stretched the wheelbase by three inches, resulting in more passenger space, while keeping the footprint the same. Under the hood, a revised 3.6-liter V6 is mated to an eight-speed automatic, forming a smooth powertrain. Handling is sound and the cabin is quiet. The ride on the optional 20-inch tires has trouble coping with some harshness. We think the standard 18-inch tires are a better choice. Inside, there's an 8-inch touchscreen, fewer buttons, and Apple CarPlay and Android Auto capability, but the unintuitive gear selector is maddening. Advanced electronic safety features and all-wheel drive are available.

New Car Reliability Prediction


All cars come with basic warranty coverage, also known as a bumper-to-bumper warranty. This protects consumers against unexpected problems with non-wear items. Powertrain warranty protects against engine and transmission troubles. Rust through, or corrosion warranty, covers rust to non-damaged components. Roadside aid provides on-location assistance in case of a breakdown and may include limited towing services.

Extended warranties provide peace of mind. Owners of models known to have worse-than-average predicted reliability can mitigate risks with an extended warranty. Generally, we recommend buying a model with better-than-average reliability and skipping this expensive add on. If you do buy an extended warranty, it is key to read the small print to understand what is covered and where you can bring the car for repairs.
