If your problem is the same as mine, you'll find that the speedometer, tachometer and probably the temperature gauge will read low. You can verify by going to the enhanced settings of the EVIC and comparing them while you drive. The dealer initially said that the cabin control module was bad. He ordered a part, it came in, but now I'm told they have to send the entire cluster back to the factory for a fix. Seems that the modules in the cluster now store the odometer readings and any cluster replacement legally requires the factory to set the correct miles on the cluster. I'll take the car back Monday and I'm told they'll have to keep it for about a week.
