Re: Temperature light not registering sometimes. Software issue?
I had issues with mine giving me a false "ENGINE OVERHEATED" warning when I was driving in -30*C temps after having it plugged on a block heater timer (about 2 hrs before leaving) in my attached, but unheated/uninsulated 2 car garage. When I pulled over, shut it off and immediately restarted it, the actual engine temp was 88*C according to the EVIC. I took it in after it did it 3 days in a row and on the third day finally set a check engine light. Dealer says Jeep is aware of the problem and it is a software issue, not a part failure in my case.
