Gen 2 speedometer issues

4375 20
Does anyone else have an issue in their Gen2, where the digital speedometer is 1.5 MPH off compared to the analog one?

Which one is right?!

Will eventually get this taken care of during my next oil change, but don't want to go out of my way to get it fixed.

They both look right to me. 45 is on the 3rd tick after 40, so 43 would be somewhere in that general range.

Honestly I still don't really bother with the analog one because it's so hard to read at a quick glance.

Does your coolant gauge sit one tick OVER 1/2 all the time?

Oh, I'll absolutely be complaining over this. While it may sound important in the grand scheme of things, I pay my hard earned money for this and I expect a certain level of service from not only GM, but the dealer I purchase from. I've complained over "lesser" things and have had them repaired.
Where does it sit at 40? 45? 60?

I haven't check that specifically, but I have noticed that the MPG calculation is if off compared to manual calculation (tank up, set trip odometer to zero, tank up, divide the odometer miles by the gas put in).
I have checked about five tanks now, and the variation has been between 99% to 90% (the computer being more optimistic).
In my previous 2011 Cruze, I checked it about seven times and it was around 97% each time.
Both of mine (2012/2016) have consistently been 1.5-3 MPG off the manual calculation.

Its just odd that Gen 1 was consistently off 97%, but Gen 2 varies 90% to 99%.
At least with Gen 2, if I assume the 90% all the time, my MPG for my commute is still better than Gen 1 at 97%. (39 mpg vs. 37 mpg) so even if the computer is off, Gen 2 is still a better car MPG for my driving.
My Gen 1 was never consistent. It could be anywhere from 1.5 to 5 MPG off (very rarely). Shrug.
