NHTSA recall 12V460000

What's wrong: Affects vehicles equipped with a 4-speed automatic transmission. On these vehicles, the tabs on the transmission shift cable end may fracture and separate.

Why it matters: If the tabs were to fracture and separate, the shift lever and the actual position of the transmission gear may not match. The driver would be able to move the shifter to 'park' and remove the ignition key, but the transmission gear may not be in 'park.' The vehicle may not be able to be restarted…

The fix: Gm will notify owners, and dealers will install a retainer over the cable end or replace the shift cable as necessary. This service will be performed free of charge. Notification to owners began on on November 9, 2012. Owners were instructed to not bring their vehicles for repair until January 2013.
