Subaru (FUJHY) has issued a recall on 2.3 million global vehicles because of faulty brake light issue. The recall affects about 1.3 million U.S. vehicle and another 1 million in North America and Japan, The Wall Street Journal reported.

The recall affects 2014 to 2016 Forester, 2008 through 2016 Impreza, and 2013 through 2017 Crosstrek vehicles. This is the largest ever recall from the company excluding the ongoing Takata air bag recall, according to Business Insider.

According to Subaru, the recalled vehicles’ brake lights can stop illuminating when using cleaning products that contain silicone are used. Gas from the cleaning products can seep into the brake lamp switch and short out the electrical contact. This can cause the brake lights to stop operating, but will allow the brakes of the vehicle to continue working, according to the Associated Press.

Subaru has had 33 reports of the brake light problem in the U.S. and said it has discovered the issue. The company said it will contact affected customers and replace the brake light switch.

Shares of Subaru stock were down 0.04 percent at the close on Friday.
