Hi all, I have a 2012 with 125k miles. Last week while stuck in traffic, after hour and half commute, I got a warning message that engine is hot and to stop safely. I turned on the heat at max level which cooled off the car and I made it home ok. I topped off the coolant which really wasn't low and decided to keep an eye on it. Last night, the same thing happened again so I'm now trying to diagnose the problem. I don't see any leaks but there is a slight smell of antifreeze when the car is overheating.
I started the car in the driveway and rev'd engine till the car wamed up and I got it to overheat again. I noticed that the cooling fan would only run for abut 3-4 seconds and stop again. It would only come on again after a couple of minutes of being off.
I turned on AC at max level expecting fan to run longer but it again only ran for 3-4 seconds. It did however turn on more frequently.
During both tests, I get the feeling that the fan isn't running at full speed. I now suspect that the fan contoller module may have gone bad but I'm not sure. It seems like the fan runs much faster when I hot-wire it directly to the battery.
Any ideas before I spend the $$ on a fan assembly because I can't buy the fan controller module separately.
I appreciate your thoughts.
