All Buick Terrazas (also pontiac sv6) violate 49cfr571. 101 in that the needles for the instrument gauges are not illuminated when the ignition is on. They are illuminated only if the ignition is off. I called this in on 1/19/2005, however, I'm using this form to mail in my complaint more expeditiously. Later a defective light sensor was found.
