Hello everyone! I have a 2017 Buick Encore , with about 114k miles on it. I have this issue that comes and goes . It started last summer where occasionally the what I believe is the radiator fan won’t shut off even after the car is off. I have left it going for over an hour and still was going. I e…

what do you mean by maintenance done? did they do anything with the radiator fans or the temp sensor?

This happened last summer too before I ever got maintenance on it. They just did a tune up , replaced spark plugs and such. At the time that I took it to the shop this issue had stopped because it was during the winter so I didn’t even think to bring it up to them.

its possible the temp sensor is going bad and causing it to read wrong and keeping it on.is the check engine light on? do you have any codes?

No check engine , no codes. As of yet . It’s only happened twice this season since it started getting warm outside so far

when you shut the car off when this happens do you here the coolant bubbling in the overflow tank?

the only thing i can think of is a faulty temp sensor thats telling your fans that the engine is hotter than it really is. maybe the other guys will have better info for this problem.

the only other thing i can think of is a faulty fan relay that is doing it intermittently

Which one? The high speed or low speed fan relay? Tester
