The time on the clock and the temperature gauge are not correct.

Asked by Jun 22, 2015 at 01:39 PM about the 2007 Buick Rendezvous CX FWD

Question type: Maintenance & Repair

The time on the clock and the temperature gauge are not correct.  If I reset the clock it is fine for a couple of days and then it will be off by a couple of hours.  The temp gauge is off by at least 40 degrees.  I am concerned this is the start of bigger problems.

The dealer maybe able to reset the computer, because two things going at the same time seems odd.

On that temp gauge, what does it mean when it shows OC, where the temp is usually shown? I just had my water pump, radiator, thermostat three hoses replaced and was hoping I wouldn't have any more over heating issues. I noticed the OC, I turned off the AC, turned the heat on to try and cool the engine. What else do I need to be concerned with?
