My fiancee is worried that a after market remote starter will void her Warranty, is this true

David is right (Thanks, David!) --- an aftermarket remote starter will NOT void the vehicle's warrantly. FTC says, "The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part.” It has to be installed correctly though (we can make sure of that)!

No but you can check with your dealership
