No Rajan. Even though you've added the word MAY, but the above scenario never happens. Thanks to FIAT's excellent implementation of thermostat control, the needle stays rock solid. I've seen that in chilly winters and blistering summers. Also, another thing to be noted here is that the mid point of the needle is so calibrated that minor fluctuations either high or low are not registered on the needle. So as not to unnecessarily alarm the driver. This has been the case since many years in well engineered cars. Cheers.
