Tesla is recalling 11,000 Model X SUVs over an issue with the second row of seats.

The automaker said that it discovered the issue during internal testing. The problem is that the cable that controls the recline of the rear seats is too tight. What that means is that when you raise the seatbacks from the fold-flat position, the left-side seat might not lock securely in place. If someone were sitting in that unlocked seat, and there was an accident, it’s possible they could be injured.

Tesla says that it hasn’t had any reports of issues relating to the seat problem, but will be conducting a voluntary recall. The company estimates that only around three percent of 2016 and 2017 Model X vehicles could suffer from the problem.

The recall can be handled by Tesla’s mobile repair service. Customers can choose to use the mobile service or to visit a service center, but either way, no new parts are necessary. The fix is an inspection and an adjustment. Customers will be notified by email starting today.

Tesla promoted their unique mobile repair service, saying that in the last two months, they’ve handled around 40 percent of the company’s Takata airbag recall repairs via that service.
