somewhere between being very unlucky or every cruze thermostat not working properly, i had yet another thermostat replaced on a 2012 cruze 1.4. both cars had the same exact issue of not getting to op temp after 25 min of driving when temps outside were below 40 degrees. the thing that made me the most mad about this happening a 2nd time is that i told them back in may it was having this issue but they told me i had to wait for colder temps to prove it. so i wasted time on two different days to go back, drop the car off, and get a ride back to get it. best part was when they told me it was ready, and i sit in the drivers seat and i see that the check engine light is on ...really, they couldnt notice that. so i pulled right back in and after a 20 min wait i was told they forgot to plug in some wire to the thermostat. on a more positive note i was happy that they asked me if i wanted the recall done while it was there, which i said no, and they didnt just go ahead and do the recall hack job on their own.
