Tesla has announced its 11th recall of the Cybertruck, this time targeting the Rear-Wheel Drive Long Range models equipped with 18-inch wheels due to a defect in the brake rotor assembly that could cause wheels to unexpectedly detach during driving.
- Faulty brake rotor studs risk wheel separation on 173 Cybertrucks.
- Incorrect grease caused lug nuts to loosen and crack rotor holes.
- Tesla will replace affected components free of charge.
What happened
Tesla announced a recall involving 173 Rear-Wheel Drive Cybertruck Long Range units due to a defect that could lead to the rear wheels detaching unexpectedly. The National Highway Traffic Safety Administration (NHTSA) notice described how the brake rotor stud holes may crack and cause the lug nuts to separate from the wheel hub during driving, especially under conditions involving road bumps or cornering forces. The root cause was traced to the use of the wrong type of grease on the lug nuts, which failed to maintain sufficient friction.
This incorrect grease allowed the lug nuts to loosen over time, which led to vibrations and stress concentrating in the brake rotor stud holes. Over continued use, these cracks could propagate until the studs separate from the hub, risking wheel detachment while the vehicle is in motion. Tesla intends to fully replace the wheel hubs, rotors, and lug nuts on all affected trucks at no cost to owners.
Why it matters
This recall highlights the complexities and risks involved in automotive manufacturing where minor material or procedural changes can have significant safety repercussions. Despite the Cybertruck’s reputation for robust build quality and futuristic design, these ongoing recalls underscore the challenges Tesla faces in production consistency and quality control. The wheel separation risk is a potentially severe safety hazard for drivers and others on the road.
Analysts note that the issue originated from a communication breakdown during production, where changes in grease specifications did not reach the factory floor on time, resulting in a small batch made incorrectly. While the number of vehicles affected is limited, it underlines the importance of seamless coordination between engineering decisions and manufacturing processes, especially in high-profile, complex vehicles like the Cybertruck.
What to watch next
Looking ahead, Tesla will likely face continued scrutiny regarding quality assurance and supply chain communication, especially as it prepares for broader Cybertruck production scale-up. The recall may prompt more careful review of ongoing manufacturing processes to avoid future occurrences of similar defects. Consumers and regulators will be keenly watching how effectively Tesla manages and rectifies these safety issues given past recalls involving Cybertruck components.
Additionally, the fact that just 173 trucks were affected in this instance may offer insight into production volume and ramp pace. Despite Elon Musk's 2023 claim of over one million reservations, Tesla has delivered far fewer units, with just over 46,000 Cybertrucks sold in the initial 14 months. Monitoring whether Tesla can increase production volume while improving reliability and safety will be critical for the pickup's long-term market success.
