“The drivers door master power switch shorts out - cannot roll down windows (of any kind), lights flicker and go out completely my headlights turn off completely while im driving!!!!! And has caused me to immediately pull over with no lights, no vision to turn them on manually!!! Unacceptable!!”
NHTSA complaint #10904306, filed 2016-09, 82,500 miles“We no sooner have our gas gauge fixed and then the speedometer stops working. At first it would move back and forth between 0 and 120 MPH. Now it just stays on 120 MPH. Since the speedometer stopped working half of the dash board lights now no longer work, neither power seat work and last week the power windows in the back seat stopped working. Obviously there is a major problem with the electrical system in this make/model because we are not the only ones with these problems.”
NHTSA complaint #10456392, filed 2012-04, 105,000 miles“My 2005 Buick Rainier had 55,000 miles on it when my speedometer went on the blitz. The speedometer was stuck at 60 MPH and would continue to rise until it was pegged past 120 MPH while traveling on the highway. This has been going on intermittently for about 9 months. Now my speedometer may stop working completely while traveling down the road. My mother has a 2004 Rainier and she is having problems with multiple gauges including the speedometer. …”
NHTSA complaint #10261378, filed 2009-03, 55,000 miles“My speedometer does not work correctly. Some times it seems to read right, but lots of times it will say I am doing 120 when I am doing 30 MPH or it will show I am doing 0 when I am actually doing 70 MPH on the interstate. I cannot rely on my speedometer to be accurate. I can be driving, it appears to be working but then it starts to slowly go down until it is back at zero and all the while I am in drive and moving. Also, my oil gage has stopped working. It moves when I start my car and shut it off, but it is never correct either. It is either at zero or on the complete opposite side. …”
NHTSA complaint #10782119, filed 2015-10, 100,000 miles“I have various types of problems with my 2005 Buick Rainier. I have owned it for about 6 years now and it currently has a little over 93,000 miles on it. I am reported the problems to you so that you can document the problems to your list and I am also hoping that you can let me know if there is a recall for these issues? 1. Awd is not working. When there was snow on the ground. It caused me to ditch my car when I was turning a corner at a very low speed. There was a car coming towards me, but missed my car. Thank goodness it did not injure someone, myself or my car. …”
