The relay for the fan at the top of the fuse/relay box on the right side when facing the front of the vehicle. (under the hood) Gets hot and blows the relay and melts the spot where the relay prongs plug in. Causing the need for a new fuse box and circuit problems within the fuse box connectors. The fans, specifically the a/c fan does not kick on when turning on the a/c and the low speed fan does not kick on at all until the secondary temp fan kicks on after the temperature raises past the normal operating range. Which an overheating engine is bad for all parts of the engine which can and sooner or later will lead to a catastrophic failure putting the operator and other motorists life's at risk.This time it created a small fire that was extinguished only because the fuse box cover was off and I was looking at it as it happened, putting the cover back on extinguished the fire. This is the third time it has happened with the exact same problem. You tube is full of videos with the exact same problem.

DRLs melted into the housing, seems like this is possibly caused by cowls that are not properly sealed allowing moisture into headlight assembly. This is obviously a fire hazard and will be a costly repair. I am not sure if vehicle insurance covers this but I doubt it.

This all began at about 75000 miles. It first started with the stabilization/traction light coming on while driving once this happened you could not accelerate the car. I once was on a highway in the middle lane when it happened I could not accelerate and had to try to get over to the break down lane. This happened several times but then turned into a completely different problem. While driving the battery would start to die with no warning. When this happens you can not jump the car you have to bring the battery to be charged on a charger. Although the car won't start the other things like lights, radio, etc will still work. This happened several times but once the weather was warm it ran perfect for 4 months. The first day it was extremely cold the battery died while driving. I also had a headlight go out on the drivers side and about 3 weeks later it came back on and stayed on. I have brought it to several places but nobody has been able to figure out the problem. I can't keep spending money to get it diagnosed with no results. After researching online it seems to be a very common problem in the acadia.
