An electric vehicle, the Dongfeng Fengguang MiniEV, purchased by Mr. Liu, a netizen from Zhengzhou, encountered an alarming issue. While driving at high speeds, the vehicle suddenly lost speed on multiple occasions, shifting from the drive gear (S gear) to neutral gear (N gear) and causing an immediate loss of power. This malfunction occurred three times within a span of less than a month. After Mr. Liu took the vehicle in for repairs, the customer service initially claimed they were unable to replicate the fault. Later, they attributed it to "overspeed overload protection," yet failed to provide a concrete repair plan. Mr. Liu found this explanation to be敷衍 (perfunctory in English, but retaining the Chinese term here to reflect the original sentiment which implies a lack of sincerity or thoroughness) and received no satisfactory response after repeatedly calling the official 400 hotline.
Accompanied by a reporter, Mr. Liu visited the Landian User Center. However, the staff there declined to comment, citing the absence of the after-sales manager. The official customer service subsequently stated that they would investigate and verify the situation. In the afternoon, the after-sales manager, also surnamed Liu, reiterated the claim of "overload protection." He mentioned that no issues were detected during road tests and advised Mr. Liu to adhere to the designed speed limit. Mr. Liu countered that the "protection mechanism" should not result in a direct power cut-off and expressed his intention to continue lodging complaints with the relevant authorities.
