In mid-September, internet users noticed a discrepancy in the official manuals for the Tesla Model Y L, a long-wheelbase version of the Model Y produced at Tesla's Shanghai Gigafactory. The manual available on the Chinese website lists a ground clearance of 169 mm when the vehicle is empty, while the global version shows a slightly lower clearance of 166 mm. Other dimensions also show minor differences, with the total height of the vehicle decreasing from 1,668 mm to 1,664 mm, and the ground clearance under load dropping from 122 mm to 118 mm. These changes represent reductions of 3 to 4 millimeters. According to an archive from June 16, these values had not yet changed at that time, indicating that the adjustments are recent. These changes come amid complaints from owners of the Tesla Model Y L, who have reported issues with the vehicle's suspension. Some users have noted that the space between the rear wheel arch and the tire has significantly decreased after long trips or when the vehicle is fully loaded, giving the impression that the SUV is sagging. These problems have been reported by owners who have driven between 9,000 and 30,000 kilometers. While Tesla has replaced the springs on a case-by-case basis under warranty, several owners say the issue has returned, and some have also experienced premature tire wear. Tesla has not officially explained the changes in specifications. When questioned about the 3 mm difference, Chinese customer service representatives attributed the discrepancy to factors such as road conditions, tire pressure, or load distribution, without offering a technical explanation. It remains unclear whether these new measurements reflect a hardware change or are simply an adjustment in the specifications. At this time, there is no official recall or communication to owners regarding the issue. The timing of these issues is particularly sensitive for Tesla, as the brand faces declining sales in China. In August 2026, deliveries of the Model Y in China dropped by nearly 26% year-on-year to 29,260 units, marking a third consecutive month of decline, according to data from the Chinese Association of Automobile Manufacturers, as reported by CnEVPost. Additionally, the extended version of the Model Y is still expected to arrive in Europe. Until then, there is hope that Tesla will take the necessary steps to address what could be a potential design or manufacturing defect.
