Quality inspectors in China have launched an investigation after receiving complaints from owners of Volkswagen Sagitar models over broken rear suspension control arms. The Sagitar is the local version of the Jetta built by joint venture company FAW-Volkswagen.

Sagitar owners made 216 complaints about the problem in the two weeks to August 12, about half the 435 complaints posted on China's national defective information collection system during the period.

Last month, FAW-VW said that the problems with the Sagitar were isolated incidents and not a design or manufacturing issue, according to Bloomberg News. The agency noted that FAW-VW said it reserved the right to take legal action against those spreading 'untrue' information.
