General Motors is recalling nearly three and a half million vehicles.

Recalled models include the Cadillac Escalade, GMC Yukon and the Sierra.

Also Chevrolet's Silverado, Suburban and Tahoe all made between 2014 and 2018. GM says the problem is a faulty vacuum pump that may force drivers to put more pressure on breaks, which can increase the risk of crashes.

GM says dealers will fix the problem at no charge to customers. At last check, there's been more than 100 crashes and 13 injuries related to the issue.
