On a recent Sunday morning at 9:30 AM, I got in my XLR and turned the key anticipating a healthy start and a wonderful top down day in Southern California. Much to my surprise, the heads up display started to come alive and the headlights came on (was parked in my garage) along with the radio, however otherwise I was greated with absolute silence.

I retried a couple of times with the same less than desirable result.

I depressed the OnStar "blue" button and a helpful voice came on the line. I described my problem and the advisor ask if she could run a vehicle probe. Since I was parked in my garage I was not sure if the probe would work, but said "sure". The advisor came back on the line to say she detected no problesms. She ask me if any warning message was display and as I said no, a "low voltage" message showed on the DIC. Then gradually a plethora of additional messages began to be displayed saying to check this, check that, this has failed, etc. In short, subsystems were failing faster than I could read the messages.

The advisor stated she would transfer me to Roadside Assistance. Roadside Assistance came on the line almost immediately. They said they would dispatch a technician from Renick Cadillac who should be on site within one hour.

Five minutes later (remember this is Sunday morning at around 9:30 AM), the Renick technician called me. He was walking to his vehicle and stated he would be on site in thirty minures.

He showed up dressed in his Sunday finest. By now the vehicle required use of the emergnvy manual entry procedure. He spent less than ten minutes diagnosing the problem and then stated I needed a new battery. Of course he had a brand new battery in his van. The battery is very small, slightly larger than a motorcycle battery. It took ten minues to change the battery and I was on my way.

Total elapsed time from my call to OnStar to when I was on my way, less than one hour.

Pretty good I would say!

The technician had two suggestiosn:
1. Limit trunk opening and closing when vehicle is not running
2. When not in use, keep the FOB put of radio range with the vehicle

I have also had this problem a few times. In my part of the world I seldom drive the car in the winter.

The good news is that there is a simple fix. I got a battery tender (bascially a very small battery charger) from the local NAPA dealer. It cost $30.00 and is very simple to install. takes less than 5 minutes. When I put the car in the garage or get ready to store the care for winter, I plug in the battery tender which makes sure the battery is at optimal performance all the time. The XLR uses a lot of battery power even when turned off.

Honestly, this would be a good feature for Cadillac to include with the car seeing how a lot of us store our XLR's for the winter. Anyway, since installation I have had no problems.

If this happens again (or to someone else), just disconnect the battery, wait 30 seconds and then reconnect. In my case the XLR just hit a "logic lock". There is a lot of software running that car and every so often the start-up software seems to get confused. I've had it happen twice.

In my case the battery was fine, although a low battery could also trigger the same behavior. Unfortunately, to tell the battery voltage with the car you need a good battery (catch 22).
