Ok about 6-8 months ago I bought a 3 piece set of the M18's it came with a 3/8 Impact rated @ 160 ft lbs a drill and flashlight combo well the impact is starting to lose power rather rapidly even using a brand new battery, I'm seeing M12 bit drivers running all over this impact. My question is has anyone here had problems like this with there impact. Does the 5 year warranty cover this type of problem? I am going to call them soon just wanted to get other peoples thoughts on this matter. Thanks
