Most of the problems are with cars built in 2012/2013. So not if you buy a 2015 car. If you buy an earlier car, either make sure it's had all the mods installed or its cheap enough for you get them completed.
Hah! I've heard this same line with every unreliable vehicle that I've owned. The truth is we won't know how reliable the 2015's are until they've been around as long as the 12's and 13's. Anything else is just wishful thinking.
