Dealers rarely offer such modifications for older vehicles. You need an independent car alarm or car audio shop. Many will also sell and install aftermarket remote starting systems.

Also check what security measures will be defeated by installing a remote starter. There is going to be a compromise on convenience and security.

Things may have improved, but any after-market modification also makes troubleshooting [if any] more difficult. We are all well past warranty coverage but the mod will be the susceptible add-on that drains the battery etc.

ps: I live south and have no appreciation of remote start warmup.

 

I had an Evostart installed on my 2015.
Has been flawless. Just check first, the phone app only works in Que and Ontario and is a 3G system.
It is free, but will be phased out in the next couple years. You will all other functions even if the phone app is eliminated, remote start by separate fob, of 3 press of lock.

This was one of the easiest installs I have done on a car for an accessory item.
