The prosecutors decided to drop the charges against automobile mechanic Park Byun-il, who was accused of business obstruction and defamation by Hyundai Motors. 
 
As the prosecutors dismissed the case, South Korea’s largest car maker disgraced itself in public after suing the nation's famous car master, who has pointed out the firm's security issues.
 
In December of last year, Hyundai Motors brought Park's interview into question. Park appeared in local consumer ombudsman TV program, pointing out security issues of Hyundai Motors including "Malfunction of Tucson ix's airbag in 2013," "Bus' sudden unintended acceleration in 2014" and "Water leak of Santa Fe and Avante MD."
 
In July, the police sent Park's case to the prosecutor with an opinion that he has no charges. Following Hyundai’s accusation, the nation's famous vehicle community was full of criticism against Hyundai Motors. Hyundai said, "We will keep an eye on the investigation."
 
Then, on Dec. 3, the Incheon prosecution dropped the charges against Park, claiming he didn’t commit any crime. 
 
Hyundai Motors also came under fire as it did not sue two other professors, who pointed out similar problems, a move that discriminated against Park, who has decent educational background. Park reportedly left school when he was 14 years old due to financial difficulty and made a living as a mechanic at a bus firm. Later, he obtained a title of "Master" in the automobile mechanics in 2002 for the first time in the nation.
 
Industry watchers said Hyundai Motors, which said it would take a wait-and-see attitude on the case, indeed made all-out efforts by additionally hiring a law firm in a bid to prove Park guilty.
