anyone else have this problem??? it sticks at 10C for about 10 min then start to jump up and up to the right temperature has happened two times so far booked it for warranty just wondering if anyone else had this problem????

 

IT happens to mine if it is sitting still for a few hours. I remeber going out one of our job sites early morning and seeing the temp right at 85*F at 5am and then coming back to the truck sweating my *** off around 2pm and it still saying 85*F, after a few minutes of driving though (Mine has to be driving above 35mph, dont know why but it does) it adjusted itself back out showed the temp at 110*F... bit of a difference there...

 

Sounds like a bad sensor behind the grill. Mine is usually spot on unless it reads high at start-up from either the sun beating on the front of the truck or it had been running and heat from the radiator caused it to get hotter.
