we just bought a 2014 LT Cruze.  shortly after buying it, the AC shut off due to high engine temp notice came on and the fan ran continuously.  We took it to the dealer and they diagnosed the issue to be a leak in the thermostat housing.  They replaced that and all was back to normal for about 4 days. Then it came back on again.  what I found odd, was that the car never overheated and the temp gauge on the cluster inside the car says it is all the way COLD.  I detached the ground wire from the battery for 10 minutes and restarted that car and the notice went away.  But for how long remains to be seen.  Is this a ECU problem? Is there an update?  This car was certified through the dealer.  I also saw a video on YOUTUBE where someone replaced the coolant temp sensors and that fixed his problem.  Please help!

I am having the same problem on my 2015 chevy cruze 53000 miles.  There are several hundred complaints throughout the web on this problem.  Seems that there should be a TSB or recall for this problem.  Has anyone made a complaint with the US Product Safety Commission?  Is Chevy doing a voluntary recall?  If not, I recommend making USPSC aware of the problem.  The light and beeper comes on but the engine is not overheating.  It scared me so badly, that I almost ran off the road today.

It's a known minor problem with a few US-built Cruze.  Not even 1% of the production run has shown this problem, it's cheaper and easier to fix it if it happens.


Take it to a dealer, or any competent mechanic, and get it fixed.


Oh, and if having lights and beepers go off in a car frightened you today, you should give up driving before the next generation of vehicles trickle down, as they are all lights and beepers!   ('Er indoors Lexus has a different tone "bong" for different and various situations, some benign, some drastic, you'd be right buggered if you were tone-deaf.)
