Vehicles Affected: Approximately 618,000 model-year 2011-14 Kia Optima sedans, model-year 2012-14 Sorento SUVs and model-year 2011-2013 Sportage SUVs
The Problem: Machining errors during the engine manufacturing process may cause premature bearing wear within the engine; this could result in the engine seizing, increasing the risk of a crash.
The Fix: Dealers will inspect the engine assembly and replace it, as necessary, for free.
What Owners Should Do: Kia will begin notifying owners on May 25. Owners can call the automaker at 800-333-4542, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or visit www.safercar.gov to check your vehicle identification number and learn more.
