Finally had to replace the original battery in my 2016 MKC Reserve 2.3L. The battery crapped out while at home, tried to recharge but it would not take a charge so I decided to replace it myself. Quite a job to say the least, thankfully I saw the video in an earlier post on this subject. I actually got the battery out without taking the air box out but getting the new one back in was impossible, way too tight. Once I got the air box out it was fairly simple. One auto parts website stated that it should be "professionally installed" and that would be great if you could get the car to the "professional". Next vehicle there are several things I will definitely check instead of being seduced by the 2.3L turbo, lol.
