Greetings all, my wife's 07 Tribeca I believe is suffering from a cold solder joint issue. When the Tribeca starts up in cold weather everything is A-OK. Once the engine warms up the following occurs-

Traction Control (Yellow) Light on the dash illuminates and remains lit-

Check Engine (Yellow)Light illuminates and remains lit-

Cruise Control (Green) light flashes and does not work -

During this episode I can't pull the OBDII Codes. Seems like there's no power at the port.

This occurrence is intermittent i.e., the car can be used all day without incident. Some days, not to lucky. On a non incident day I connect the OBDII computer and after sampling the data, zero codes are logged.

I'm wondering if the root cause is a cold solder joint thus between the expansion/contraction cycle something's amuck.

Any other theories ?

Thanks,
