I have a 2012 Chevy Sonic, 5-speed manual tranny, which I JUST LOVE... HOWEVER... I have a cooling fan issue. The fan runs when it shouldn't. The shop I had my car in to said that is normal, when you have the A/C or defroster on. I don't have either on. It's now so bad, that it runs all the time, and even when I shut my car off, it will continue to run! What I am wondering... is this covered under my powertrain warranty? I can't afford to bring it in to the dealership, unless it is. The shop I've gone to seems to be at a loss. The dealership should know how to fix it, right?

Can anyone answer these questions? I see many have viewed the post, but I'm still hoping for answers.

 

You say it continues to run after you shut the engine off. How long does it continue to run? Is it for a few minutes or for ever? If the engine is at a high temp when engine is shut off then the fan will continue to run for a few minutes to cool down. If it runs for a long time after then maybe the temperature sensor is bad.

 

Oh a reply! Thank you!!! I'll try to explain it better. I'm in MN... it's cold out. I start the car, and the fan will immediately come on. It will continue to run a good couple of minutes, when I turn my car off, as well. The engine light is on now, and when I had it in to the shop, they said the error codes were the thermostat. I had purchased the assembly (stupid.. can't buy just a simple thermostat for this car) but they said it's not that, so never installed it. The engine light goes out intermittently and then back on again. It has stayed on now, and the fan issue seems worse. So I was hoping this would fall under the power train warranty, as my bumper to bumper is no longer. The dealership is SO EXPENSIVE, but they most likely can fix it, compared to the shop I had it in to previously. Make more sense?

It could still be the temperature sensor. You can also take it to Autozone or Advance Auto and they will read the codes for you for free.

 

Thank you, Helen. I actually did finally just bring it in to where I purchased the car. I have to give a shout out, if I may... Wilcox Cadillac and Chevrolet in Forest Lake, MN... class act!!! They treated me well, provided me with a fine loaner car, and repaired my car at the least cost to me, that they could. I'm glad to have my baby back and running smoothly!!!!!

 

post what the repair was. this will help other members.

 

My apologies... obviously, I didn't think of that... they replaced the Cooling Housing Assembly, along with a few other things, that included a wire that had been pulled out (we think by the previous shop) along with the air intake tube, that was clearly damaged, again due to the extent of this damage... done by the previous shop. Again, I am very pleased with the treatment I received from Wilcox Cadillac & Chevrolet. My car is running great! And they stand behind their services. There was a minor issue that came back with my radio, from the detailing I had done. They are replacing the radio!

 

Good to hear you are being treated well . :-)

I would have repaired things myself .

Live long and prosper . :-)

God bless
