More than 72,000 cars subject to recall are still on the road, a report showed.

According to automobile data submitted Monday to lawmaker Jeong Yong-ki of the ruling Saenuri Party, some 3.8 million vehicles have been subject to recall by the authority since 2011. Only 3.1 million, or 81 percent, were collected and fixed by automakers, the report said. 



The remaining 725,549 cars have been untouched.

Meanwhile, the report said Renault Samsung did the best in handling potential defects, recalling 89 percent of faulty vehicles, the highest figure among domestic automakers.

Following is Kia Motors with 86 percent of vehicles recalled, Hyundai Motor with 80 percent and GM Korea with 73 percent.

Among imported cars, Mercedes-Benz Korea scored the highest 97 percent of collection rate upon a recall order, followed by Hanbul Motors (91 percent) and Volvo Car Korea (86 percent).

Honda Korea, however, was poor at expediting recalls, collecting only 40 percent of defective vehicles.

Similarly, BMW Korea failed to fully execute a recall order issued on Dec. 2013 for door latches over its 7 Series 750Li, collecting 33 units out of 233 (14 percent) as of Wednesday.
