READ ALSO Tesla Model Y L reportedly faces surge of owner complaints over rear suspension collapse in China Discrepancies in Ground Clearance Data Recent checks of Tesla’s official owner manuals have revealed inconsistent data regarding the vehicle’s unladen ground clearance. While the tesla.cn website (link, archived) continues to list the ground clearance at 169 mm, the tesla.com version (link, archived) now displays a figure of 166 mm. It’s not just this one parameter that has been modified, the vehicle’s total height has been reduced to 1664mm, the laden ground clearance to 118mm, and the unladen ground clearance to 166mm. These three parameters have been reduced by 4mm, 4mm, and 3 mm, respectively. By checking the Wayback Machine, CarNewsChina found that as of 16 June this year, Tesla had not yet modified the relevant parameters. When questioned about this 3 mm ground clearance discrepancy by NBD, Tesla China customer service did not provide a specific technical explanation. Instead, representatives suggested that wheel arch height can be influenced by various external factors, including road surface flatness, tyre pressure, vehicle load distribution, and general chassis condition. Tesla has yet to issue an official statement regarding whether this change in documentation reflects hardware or technical specification adjustments. Model Y owner’s manual page on Tesla.cn.

Owners report that the gap between the rear wheel arch and the tyre narrows significantly after long-distance travel or when the vehicle is fully loaded. Reported incidents: Owners have documented issues ranging from 9,000 km to nearly 30,000 km of usage. Consequential damage: The suspension drop has been linked to abnormal inner-tire wear, with some owners claiming tyres have reached safety limits prematurely. Service Response: While Tesla has replaced springs under warranty – notably using a new part number (2188477-00-B) compared to earlier “A” suffix versions – some owners report that the issue persists even after the replacement. The new springs with part number 2188477-00-B VS the old 2188477-00-A ones. Tesla’s internal service guidelines reportedly define a “normal” rear wheel arch height as 784 ± 20 mm, with spring replacement authorised only if the measurement falls below 764 mm. As of now, Tesla has not disclosed the root cause of the rear suspension height abnormalities, leaving many owners seeking a permanent solution beyond temporary spring replacements. Some Tesla Model Y L owners have started manually measuring the ground clearance. Most important news in your inbox. Recaps · scheduled All you need, in one email.
