after being at the dealer 5 days

still there, dealer calls , says thats normal, for temp needle not to move, it does go to cold position, then as it warms. it goes to 1/3 position,
even when DIC reads 205, needle is still 1/3,
I took pics to show dealer, they weren't concerned,

so I went to same dealer, looked at a new impala, started it and watched the temp needle climb, sitting there, a/c on, scrolled to DIC. and temp gauges went up as DIC did,
SO, ITS OBVIOUS this dealer is full of shit,

wow, thought they weeded out the flaky dealers,

With an OBD scanner running mine reads just over 200F while driving, normal op temp. but I will say this... On my 2013 GMC if there is any kind of thermostatic failure (yes even too cool) the "engine hot a/c off " light will come on (you read that right, too hot OR too cool), this is instantly noticeable in summer as the car does in fact shut the a/c off... I would imagine this behavior to exist in Impalas as well and it is sensitive, even the wrong temperature thermostat will set it off.

How I found out, I switched from a 180-degree to a 170 one on my GMC.
Again I'm sure the behavior would be there on Impalas so my attitude with this is if it runs, don't fix it.

Also you can turn on your heat at full blast and so long that is coming out the vents HOT I wouldn't worry further.

different dealer

took the car to a different dealer, they agreed , dash gauge is sluggish, and does not show warmer temps, ( like 205 on DIC)
but is within parameters,
we have 20 or so of these in the county fleet, and none over heat, or even come close, so won't worry about it,

yes , it causes concern , but not gonna let it bother the nice ride the car is,
we went to PHX earlier this week and for 470 mi, averaged 34 mpg,


on another note.
windshield is de laminating, has mini bubbles all thru out the windshield, makes night driving fun, like driving in the rain, with NO wipers.
new dealer said they expect to replace windshield. (waiting approval)
