Discuss the causes and fixes for P1217 Infiniti OBDII Code

I have a 2008 Infiniti m35x and I currently have the p1217 code. I replaced the thermostat and the radiator and cap. It is still overheating. Should I replace the engine coolant sensor?
-
You probably need to bleed the coolant system. You have to use an special tool to bleed the coolant system otherwise air trapped in coolant system will cause an overheat problem.

I have a 2016 Infinity QX50 with only 54,000 miles, the cars speed dropped and started jerking and went down to 20mph and wouldn't go over that speed, it started running hot. We stopped and loaded car on a trailer and took to Infinity Dealership next day. We were told it had a Radiator Tank Leak on right and left side of radiator tank, hoses were swollen, it had error code of P1217 Overheat. They recommended to replace radiator assembly, upper and lower radiator hoses, thermostat. They couldn't tell us WHY this happened in the first place. I researched and asked if they could do a PCM software update to address this issue, as the update would include revised cooling fan operating parameters. The research also stated failure to complete both service procedures may result in a repeated radiator failure. The Service Person told me specifically, "we do not have anything like that on our vehicles in regards to the cooling system"? This is weird, it's the COMPUTER OF THE CAR and Infinity should have this PCM Software in their vehicles. I need to know why this happened.
-
I'm not aware of any PCM software updates regarding the cooling system or the cooling fans. I have also checked all Infiniti Service Bulletins and a national database of repairs for your model and year, and there is no information about cooling system bulletins or PCM software updates either. More than likely the problem was just a radiator failure and as preventive maintenance, they are recommending the radiator hose and thermostat.
