Impossible to read speedometer & other gauges during sunlight. Gauges light up at twilight,but, not during daylight hours. This is a safety problem and cannot be corrected at the dealership. This condition has existed since the time the new vehicle was driven from the showroom.
You can not read the dash board instruments in the day time. You can not see how fast your going, how much fuel you have or if you are over heating. Which makes for unsafe driving. At night the dash board instruments are well lit and you can read every thing. I've reported this to the Buick dealer with no results. This defect is on my new 2006 Buick Lucerne lxs.
