2015 SLE, 52k miles. Engine cooling fan comes on...loud...full blast and won't turn off. When this happens, coolant temp sensor stops working, and AC compressor also stops working. If I turn off the car, and restart...all is fine...until it happens again. Thoughts? (ps: even happend in early spring when it was 40 degrees out...but granted it was at idle. Now happens usually under load, and when idling)
