Vehicles Affected: Approximately 500,000 model-year 2011-12 Hyundai Sonata sedans manufactured between Dec. 11, 2009, and April 12, 2012, at Hyundai Motor Manufacturing Alabama and equipped with either a 2.0-liter or 2.4-liter direct-injected gasoline engine
The Problem: Metallic debris may not have been fully removed during manufacturing of the engine crankshaft, which could restrict oil flow through the connecting rod bearings, causing damage to the connecting rod. This will produce a metallic, cyclic knocking noise from the engine and could possibly cause engine failure, resulting in a stall and increasing the risk of a crash.
The Fix: Dealers will inspect the vehicles and replace the engine assembly, as necessary, for free. In addition, the automaker will increase the warranty for the engine short block to 10 years/120,000 miles for both original and subsequent owners of all vehicles identified in the recall.
What Owners Should Do: Hyundai will begin notifying owners on Nov. 2; owners will receive a second notification later when parts become available. Owners can call the automaker at 855-671-3059, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov for more info.
