Having a issue with cold starting my 08 qx56

[ddakan77]

I have replaced the battery but anytime the temperature gets below 10 degrees I cannot start the qx56. It will not turn over anyone have any ideas?

Could oil weight be an issue or I have done some reading that people were having issues with the ECM relay or IPDM?
Any ideas? Thanks for the help!

need lots more info. hard to diagnose over the internet.

are you the only owner?
is purchased used, how long have you had it?
when did this start to happen? made any mods to anything?
checked the obd port for any DTCs?
have you changed the oil?
what part of the world are you living in? how cold is it? does this happen at any low temp or certain temps?

could be ipdm, could be ecm, could be cam position sensor, could be anything but one needs to find a common denominator first.

I live in Denver CO. I change the oil every 3000 miles. I did purchase it used. It seams to only happen when the temperature gets below 10 degrees, which in colorado is only a couple of weeks a year. I have not made any mods... the obp port did not have Any dtc's.

Thanks

oil cant cause the issue.

could be a faulty starter solenoid, or any faulty sensor that will prevent the engine from turning over.

this may not be something one can diagnose over the internet....
