GoPro has issued a recall for the Karma, the action camera maker’s first quadcopter drone. The company says that the recall was issued due to safety concerns surrounding incidents of power failure.

GoPro has already sold 2,500 units of the Karma drone. which has only been on the market for 16 days. All of those are being recalled. “Safety is our top priority,” GoPro CEO Nicholas Woodman said in a press release. “A very small number of Karma owners have reported incidents of power failure during operation. We have moved quickly to recall all units of Karma and provide a full refund while we investigate the issue.”

GoPro said that it discovered a “very small number of cases” of Karma units suddenly losing power while being used. The company added that there has been no related injuries or property damage reported yet. GoPro executives did acknowledge last week it was having production issues with the Karma, but there was no mention of power issues or plans for a recall at the time, according to The Verge.

GoPro stated that customers will be able to get a full refund directly from GoPro, or from where customers bought their Karma units. Customers who wish to get a full refund don’t need the original receipt, but they are required to return all of the Karma’s parts, including the Her5 Black and the Karma Grip gimbal, according to Engadget.

The action camera maker also warned customers that there are no replacement units being offered, but it is planning to resume sales of the Karma drone “as soon as the issue has been resolved.”

The recall arrives just a week after GoPro announced that it failed to meet revenue expectations by 23 percent for the third quarter of 2016, as pointed out by TechCrunch. The company was banking on the success of the Hero5 Black, Hero5 Session and the Karma to bounce back during the fourth quarter onwards.
