The Xiaomi SU7 high-speed collision and explosion incident continues to ferment. On April 2, a letter in the name of Lei Jun, "A letter to all users and the public who care about the Xiaomi SU7 accident", was circulated online. The letter mentioned the aftermath of the accident, including commitments to find the truth, reflection and action, transparent communication, and ten years of adherence to the safety commitment. It mentioned that if there are problems with the vehicle, the sales of the relevant vehicles will be stopped immediately and the vehicles that have been sold will be recalled unconditionally; Lei Jun will personally donate 100 million yuan to establish the "New Energy Vehicle Life Guardian Fund" and jointly launch the "Extreme Collision Power-off Technology" with CATL. But soon, someone in the industry called the screenshot fake. The publisher was a senior car reviewer, who deleted the picture and said "That picture is fake, sorry." The reporter contacted Xiaomi, and Xiaomi responded that this was fake news. At present, Xiaomi's official Weibo and Lei Jun's personal Weibo have not released the above information. On the evening of April 1, Lei Jun said that he "will stand up" to solve the problem.
