2011 GMC Acadia: engine overheating

Filed May 10, 2026 · Electrical · KS · fire

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.

The 2011 gmc acadia vehicle at 38k miles suffered a major leak in the cooling system.per the federal safety agency id number 10052213 & pb-13079, the fix did not stop the coolant leakage around the water pump seal. With the vehicle at 38k miles the dealer tested and charged for the replacement of the water pump. This should not have happened with this low mileage. The manufacturers safety issue in my part was unsatisfactory do to the replacement of the defective part not under warrenty.

Daytime running lights have overheated on both sides and have melted the plastic housing. The lights are extremely hot in a confined space and are in very close proximity to a flammable material. I noticed smoke coming out of the headlight and saw that it has melted the housing to the point where the bulb is now sitting directly on the melted plastic housing. These are the running lights....not the main headlights.

We purchased our vehicle in june of 2014. We have had to replace the driver's side headlight 4 times since we purchased the vehicle. Since the tire needs to be removed and the wheel well cover needs to be removed in order to change the light, we have to pay $80 each time we change the bulb. 4 times in less than two years is ridiculous. I have seen other complaints regarding overheating bulbs, so I will have that looked at next.

Daytime running lights bulb melting, both left and right side, resulting in burning of headlight housing. Bulb can no longer be held in place because mounting fixture is melted away. The existing bulbs are made of plastic. I believe the filament is overheating the plastic bulb and causing a potential fire hazard.

I noticed headlight wasn't working and went to auto parts store to replace bulb. Attendant looked at it and said plastic assembly holding headlight bulb was melted and discolored as if the bulb was overheated.. We worried that it could have caught on fire so took it to sandoval gmc where we purchased the vehicle new. Left it to have replaced and they called and said the other headlamp assembly has melted as well. Both would need to be replaced to insure no danger of fire. The quote to replace $1,917.01 yes that's right one thousand nine hundred dollars and one cent. They said they would try to get a better price and they did. When we picked up the car they took an "insurance" discount off in the amount of $1,150.20. Still our cost of $824.32 was beyond belief. If this happened to two of two oem parts think how many are on the road. Do I hear "recall"?

I noticed the passenger side drl was not functioning properly - it was out. I subsequently checked the passenger side headlight and found it was working intermittently as was the passenger side drl. The vehicle was taken to the dealer for further inspection. The inspection of the malfunctioning drl determined the housing had overheated and some of the wiring and the reflector for the drl were melted due to apparent overheating. As a result of the overheating, the entire headlamp assembly had to be replaced. Given the apparent heat build up in the headlamp assembly, this is a possible fire hazard. Additionally, given the intermittent operation of the headlamp adjacent to the drl this could be a safety hazard if both headlamps were to fail simultaneously while traversing a very dark country road at night. A review of the internet indicated this is an ongoing problem with this vehicle dating back to 2007.
