Approximately 168,000 vehicles are being voluntarily recalled by Hyundai and Kia to take care of problems stemming from previous recall fixes.  A faulty fuel pipe problem could cause engine fires.  Prior to the Federal government shutdown, the auto makers were under investigation by the United States National Highway Traffic Safety Administration.  With that agency furloughed, Hyundai and Kia have decided to move forward on their own.

According to news reports:

Hyundai and Kia started recalling 1.7 million vehicles in 2015 – about 618,000 of which are Kias – because manufacturing debris can restrict oil flow to connecting rod bearings. That can cause bearings in 2-liter and 2.4-liter four-cylinder engines to wear and fail. The problem can also cause fires. The repair in many cases is an expensive engine block replacement.

Problems have remained.  Both companies have now suggested that the fixes may not have been done the right way at all dealerships.  The car manufacturers plan to contact the owners of the affected vehicles directly by mail.  However, dealerships can also check the fuel pipes of vehicles for potential leaks.
