I bought my car used 2/24/17 since then I have out 3 engines and 2 radiators and my car is back down again.
I noticed a couple of times in stop and go traffic that my temperature indicator started to inch its way over to hot, never reaching the mark. I told my husband and he said I probably need a flush and new coolant. Took the car to dealership and I had a leaking intake gasket and needed to be repaired. Very expensive! had oil in the radiator with hardly any liquid left. I started to read about other complaints and there were several so decided to report this so others will know they are not alone.
