Tesla has issued a new Service Bulletin offering a free upgrade to the High-Voltage (HV) battery seal system on select Model S and Model X vehicles. The bulletin applies to vehicles built between January 2021 and October 2025 in the U.S. and Europe.
The upgrade is being offered to address potential issues with the HV battery seal system, which could lead to water intrusion and potentially cause a short circuit. This could result in a loss of propulsion and increase the risk of a fire in extreme cases.
Owners of affected vehicles will be notified by Tesla and provided with instructions on how to schedule an appointment for the free upgrade. The service will be performed by Tesla service centers at no cost to the owner.
It is recommended that owners of Model S and Model X vehicles built within the specified timeframe check their eligibility for the upgrade by contacting Tesla or visiting their nearest service center.
This proactive approach by Tesla demonstrates the company’s commitment to ensuring the safety and reliability of its vehicles for its customers. By offering this free upgrade, Tesla is taking steps to prevent potential safety issues and provide peace of mind to its customers.
