SERVICE BULLETINS

A note about service bulletins...when any electric vehicle manufacturer publishes a service bulletin about a product it is not necessarily an admission of a bad product design nor a fault in assembly.  A bulletin is simply one method of demonstrating a way to improve their product and share that information so vehicle owners can have a better overall product experience.  

Documents are not to be altered or sold in any way.  These documents are shared as a courtesy and much time has been spent by Columbia, Tomberlin and EV Technical Services to make these available to you.  Please be respectful and considerate.

Service bulletins are NOT automatic warranty upgrades.  Bulletins are issued to inform technicians of changes for any of the following reasons: 

• Informational tips for troubleshooting;
• Material changes;
• Obsolescence of a certain part;
• An in-process change of a component or assembly;
• Various other reasons.
