Our 2005 Buick Rainier started acting up this past summer when the blower stayed on when car shut off. . Now when we turn on the heater on the car hesitates and stalls out while driving! the volt gauge is maxed out. . . The passenger window doesn't work now? now the blower doesn't work unless I fool with wires in the glovebox going to some black box? I also noticed front headlight always flickers when driving . . Even replaced bulb! always dimmer?? now we smell wires burning from somewhere. . So many problems !! over 100;000 miles on it. . . .
The speedometer does not read the correct speed. Sometimes while traveling at 55mph it will state I am only going 40 while other times it will state I am going 120. Sometime when I start my vehicle the needle will read below 0 and others it will read over 80 while just idling. This on top of the gas gauge not reading accurately, stating I am almost out of gas after I just filled it tells me there is something majorly wrong with the electronics on this make. All I had to do was put in the words "2005 Buick Rainier speedometer gas gauge failure" and found way to many incidents of the same problem. I contacted Buick and they are going to send me to have it looked at, I have a feeling they are going to charge me. And I think it should be their responsibility since it seems to be a prevalent issue and my vehicle only has 60k miles on it for an almost 8 year old car. If I have to pay for it, it will be the last gm car I purchase. Especially since my grand daughter is getting of driving age and I wanted to pass this on to her.
Gas gauge failed reads less than 1/8 tank. Warning for low fuel alarm comes on even after full fill-up. Check emission light periodically turns on.
