On the 2017 Buick LaCrosse, rear suspension toe-links on certain LaCrosse sedans were improperly installed and could loosen and disconnect (recall 17V267000), and a later expanded campaign covered toe-links that could fracture due to corrosion in salt-belt regions. A disconnected or broken toe-link causes a sudden loss of vehicle control and a significant crash risk.

Common Symptoms

Clunking or knocking from rear suspension
Rear-end wandering or loss of control
Uneven rear tire wear
Loose-feeling rear end

How to Fix

Under the applicable recall, dealers inspect the left and right rear suspension toe-link assemblies and correct the installation or replace corroded links free of charge. Owners in road-salt states should check for the expanded toe-link recall by VIN and have rear suspension inspected.

On the 2017 Buick LaCrosse, on certain third-generation LaCrosse models, the electrical connectors for the Electronic Power Steering (EPS) system were not properly sealed, allowing water intrusion that corrodes the connectors. The resulting fault can cause a sudden loss of power steering assist, increasing crash risk, particularly at low speeds. GM issued NHTSA recall 17V116000 to address it.

Common Symptoms

Sudden loss of power steering assist
Heavy / hard steering
Power steering warning light
Intermittent steering assist

How to Fix

Under recall 17V116000, dealers inspect, correct the seal seating, and secure the EPS connector seals free of charge. Owners should verify the recall has been completed by VIN; if assist is lost, have the EPS connectors and module inspected for corrosion.
