What owners report

Tl* the contact owns a 2005 Buick Century. While driving approximately 60 MPH, the low beams stopped working and hindered the contact's visibility while the vehicle was in motion. The contact had to hold the switch to get the high beams to remain illuminated due to the failure. The vehicle was taken to a dealer where it was diagnosed that the multi-function switch on the column for the lights needed to be replaced, including prematurely deteriorated ground wires. The dealer stated that the parts were to be ordered, but were not yet available for them to provide a specific date of when the part would be available to complete the repair. The contact left the vehicle at the dealer until the part was available. The manufacturer was notified of the failure. The approximate failure mileage was 118,000.

The multi function switch does not work properly. When going around curves and corners you can't dim the headlights. Because the steering wheel doesn't allow the lever to go far enough to catch. Now my headlights will not turn on when the they are suppose to. My cruise control doesn't work. My A/C stops cooling when the speed reaches 60 MPH but if I move the m.f.s. (aka turn signal) it gets cool again for a few minutes. The other night my lights went off when I was meeting a car with its headlights on bright. It was a dark stretch of road. I almost ran in the ditch.

I had driven my 2003 Buick Century at least halfway into a parking space in a parking lot when it suddenly lurched forward like a bat out of hell, leaping up over a curb on an upward slope, swiping a cement lightpost on the left, crashing into another car across its left front, bumping down over a curb, then crashing up and over two more curbs. With divine help I was able to avoid other cars and steer it to a stop, then drive gingerly into the original parking space. Since I was originally in the process of slowing to a stop, my right foot was on the brake at all times. I had never heard of many automakers' infamous "sudden unintended acceleration" manufacturing defect and had no idea what was happening as the car went from 1 or 2 MPH to full throttle instantly. …

Horn button is part of air bag. The horn button shorts out and the horn blows all the time. Have to remove fuse to stop horn blowing. Had to replace air bag to fix. In a few months the problem reoccurred. Its too expensive to replace air bags so I am left without a horn this is a safety issue. Can the manufacturer provide a fix? The internet shows this is a very common problem for a lot of GM cars.

2002 Century · 150,000 miles · Mar 2017

This is an addendum to complaint/odi #10499646...this was the scariest experience of my life, driving alone in darkness, at 55mph, and without warning, headlights & dash just shut-off !! No other vehicles on road to help light my way, couldn't see anything, almost ran off the road & got killed, only had this car 10days!! Thought I got a good deal too, but now I'm stuck with a car I can't drive at night. Spoke directly with GM customer relations specialist on 3 separate occasions, who sent me to their GM dealership for inspection. After GM rep spoke with their dealership, they decided due to the age of the vehicle, and mileage, they're not responsible to assist!! I cannot understand, nor will I accept, how this situation could be anything other than a "safety issue"!! …
