NHTSA Complaint #11675226 — 2020 TESLA MODEL X

I would like to report a significant safety concern affecting Tesla Model X vehicles, and potentially Model S as well. Numerous reports across Tesla forums have highlighted persistent issues with unadjustable negative camber, which results in excessive inner tire wear on all four wheels. In some cases, owners have reported needing to replace their tires as early as 5,000 miles. In my own experience, I had to replace mine at just 14,000 miles. Additionally, I’ve experienced repeated failures of the front axle half-shafts on both the left and right sides. The first replacement occurred at 14,000 miles under warranty, and the second at 38,000 miles—this time at my own expense. Independent automotive professionals have pointed out that the angle at which the half-shafts are installed is too steep for optimal performance. The front motor sits significantly higher than the wheels, forcing the half-shafts to transfer power at an extreme downward angle. This off-axis setup, combined with the vehicle’s weight and high torque output, contributes to accelerated wear of internal components within the half-shafts. Over time, this leads to fatigue and surface damage, causing noticeable shuddering or vibrations during acceleration. To resolve this issue, the half-shafts would need to be more closely aligned with the wheels (on-axis) to reduce mechanical strain and eliminate the root cause of the vibrations. I urge Tesla to further investigate and address this recurring issue, as it impacts both vehicle safety and long-term ownership costs. A safety recall should be issued and reimburse out of pocket expensive back to owners.
