During the testing phase of the Zunjie V800, it was discovered that the brake pedal brackets in three test vehicles suffered physical fractures. This particular model leverages Huawei's Harmony Intelligent Automotive Solution for its full-stack intelligent technology, with JAC Motors handling the complete vehicle manufacturing process. The Zunjie V800 was officially launched in August, with large-scale deliveries commencing at the end of September. Zunjie has announced that it will finalize the brake pedal upgrade plan by the end of October, complete the upgrades in November, and replace the brake pedals with upgraded versions for all users who have already purchased the vehicle. However, deposits paid by users who have pre-ordered a car during the lock-up period are non-refundable. The previous explanation released by the brand failed to mention the cause of the fractures or the upgrade plan. Additionally, stores have provided inconsistent information regarding the availability of free upgrades. Due to these safety concerns, some potential car owners have decided to forgo taking delivery of their vehicles, even at the risk of losing their deposits.
