Buick Regal recall addresses rear suspension control arm corrosion

General Motors and the National Highway Traffic Safety Administration (NHTSA) have announced a new recall for 2012-2013 Buick Regal Turbo and GS models. This marks the third service campaign addressing the same core issue: rear suspension control arms that may fail due to improper corrosion protection. Similar defects prompted recalls in 2021 and 2022, but some vehicles missed those repairs and now require part replacements.

The defect stems from a flaw in the electrochemical coating (e-coat) process, which compromises the control arms' corrosion resistance. Over time, the component can deteriorate completely. A broken rear control arm alters suspension geometry, reduces directional stability, and raises the risk of losing vehicle control—particularly at higher speeds or on slippery surfaces.

Under the new campaign, dealers will replace the rear control arms and adjustment bolts with parts from non-defective batches. The work will be performed at no cost. The recall targets vehicles registered in U.S. "salt belt" states, regions with high corrosion levels due to winter road treatments.

Approximately 17,050 vehicles are potentially affected. Owner notifications will begin on April 13, 2026. Vehicle owners can check for recalls using their VIN on the GM Owner Center website.

The fifth-generation Buick Regal was not officially sold in Russia, but it appeared on the imported car market as an alternative to the Opel Insignia, with which it shares a technical platform. On the Russian secondary market, cars from U.S. auctions sometimes exhibit suspension corrosion defects—especially those from northeastern U.S. states. Owners should pay close attention to inspecting rear control arms and suspension struts, as failure of these components can occur unexpectedly.
