xlr (how did you manage to get that ID?), Make sure you take your XLR back to the dealer on the fob issue. There are a few known instances of what you describe. For my XLR, the fob and receiving electronics were replaced. I'm told Cadillac is working on narrowing down the offending part so that the whole system doesn't have to be replaced.
Here is a rough description of the issue:
- At some attempted engine starts, the message "Fob Not Found" is displayed. Without the fob moving, pressing the start button again starts the car (may take a few tries).
- When the ignition off button is pressed, "No Fob - On or Accessory" (that phrase may be slightly off - I'm going by memory) is displayed and the accessory mode is entered. This again goes away with the next press of the Off button.
- There are parts of the XLR where the fob works perfectly but other parts of the car where it works xx% of the time. The percentage will vary depending upon the fob location.
- The physical location of the XLR does not change whether the above occurs or not.
What I'm describing only covers situations where all four of the above are happening.
Again, if so, then you should have your dealer check your XLR out. They should contact tech assistance for help. Since the electronics and the fobs were replaced my XLR is working perfectly.
