I first noticed the problem with the speedometer a couple of years ago, in 2009. The weather was cold, and I attributed it's disfunction to the cold. Then the other gauges started to show malfunction. When it got to the point that none of the gauges were correct, I went to two gm dealers and received no concern from either of them. They did not even acknowledge that they knew of a problem. I had to pay $400 to replace the dash cluster. About this time I received a letter from Chevrolet regarding the relay resistor or wiring connector on my silverado, saying they could overheat and the hvac blower might not function. I was given 10 years from date of purchase or 150,000 miles, whichever occurred first, to have this corrected if necessary. I called gm and asked why they would extend the warranty on the truck but would not even acknowledge the problem with the Buick. Again, no concern was shown. The person I spoke to was in the philippines! why would she care? we're askedto buy american, but we have to talk to someone in the philippines when there's a problem! also, I've had nothing but problems with the lights, all of them, inside and out. Couldn't tell you how many I've had to change! at the present time, we have no radio and heater lights. Goodbye gm, hello Honda!.
