JMS® Product Warranty

JMS warrants to the original purchaser the following:

Your JMS Product will be free from defects in materials and workmanship for a period of three years from the original purchase date. The warranty covers the product itself, not the cost of removal and re-installation of the product. JMS may extend the limited warranty on a case by case basis, considering the circumstances of the warranty claim. JMS products that are not installed according to the supplied instructions may not be covered by warranty.

  • If the product case has been opened or the product has been modified or repaired.
  • If the product was not installed correctly or exposed to the elements (if applicable).
  • If the product has been tampered with or damaged by: negligence, misuse or accident.
  • If the product enclosure has been opened or contains missing components.
  • We will not reprogram, re-purpose or update any product to support a different vehicle other than the vehicle it was designed to support from the factory.
