Chinese owners of the Tesla Model Y L, a three-row version of the Model Y, are reporting rear suspension collapse issues on social media. The problem is most prevalent in vehicles from the first production batch delivered in September and October 2025.
Users have developed a 'finger test' to identify the issue: if fewer than three fingers fit between the wheel and the wheel arch, the suspension is likely affected. A more precise measurement using a tape measure shows that vehicles with a height of less than 764mm qualify for a replacement under Tesla's service guidelines, while normal heights range from 764-804mm.
Affected drivers report a 'swaying' sensation at the rear of the vehicle, which can impact handling and lead to premature tire wear. While most repairs are currently handled under warranty, some owners report that the issue has recurred after service.
The problem has been highlighted on platforms such as Sina.com, CarNewsChina, and smzdm.com, with reports appearing on Xiaohongshu. Tesla China has not yet issued an official statement regarding these failures.
This follows other suspension concerns, including a US NHTSA probe into front suspension failures and high defect rates in Germany. It remains unclear if the US-assembled Model Y L, launched in July, will face similar issues as the Shanghai-built models.
