CBS: Hyundai/Kia Recall because of failed previous recall repairs.

Hyundai Plant--Montgomery, AL

The fuel injector pipe recall covers some 2011 through 2014 Kia Optima cars, 2012 through 2014 Sorrento SUVs, and 2011 through 2013 Sportage SUVs, all with 2-liter and 2.4-liter four-cylinder engines. Also covered are many 2011 to 2014 Hyundai Sonata cars and 2013 and 2014 Santa Fe Sport SUVs.
The companies said owners of the recalled vehicles will be notified by letter.

Detroit — Despite a government shutdown, Hyundai and Kia are moving ahead with a recall of about 168,000 vehicles to fix a fuel pipe problem that can cause engine fires. The problem stems from improper repairs during previous recalls for engine failures.
The affiliated Korean automakers have been dogged by fire and engine failure complaints from across the nation. They're both under investigation by the U.S. National Highway Traffic Safety Administration, which has been trying to figure out whether initial recalls covered enough vehicles. But the agency is mostly closed due to the shutdown.
In addition to the recall, each automaker said it will do a "product improvement campaign" covering a total of 3.7 million vehicles to install software that will alert drivers of possible engine failures and send the cars into a reduced-speed "limp" mode if problems are detected.
