Failure Date: 05/15/2011

Driving towards a stoplight and the brake pedal went to the floor on a 1996 Buick Century. Pumping gave only partial rear braking. Drove to friend’s house (during which the brakes worked normally the whole way). We pulled the driver side tire and discovered that the fibrous finely woven tube cover (fiberglass?) to the extremely thin and fragile wires to abs sensor looked burnt. Cutting it off we discovered the wires inside had shorted out. When we cleared the short and individually wrap insulated the wires, the abs warning light then came on. A gravel skid test revealed no abs at all. We found that dead shorting the wire to the sensor with a jumper wire will cause the abs warning light to go out, but obviously disables the abs. We replaced the sensor (which requires that the whole bearing/stud assembly to be replaced), and then the abs light went out. A gravel skid test revealed the abs working fine and he says the normal braking is now better too. Some research reveals that the abs detects no tire turning during a skid via the sensor, and releases hydraulic pressure to the brakes until the tire is detected by the abs as turning. We think that when a short to the sensor occurs, the sensor can’t detect the tire turning again and thus the abs unit never stops bleeding fluid pass the brake (and the initial short may even set off the abs without an actual skid occurring - that is without the sensor ever sensing a tire not turning). Anyone having random near-total or total loss of brakes on this type of vehicle might do well to examine the wires and terminals leading to the abs sensors - and replace suspicious units (we paid about $90 for a unit from a common auto parts chain). A gravel skid test might also reveal an abs system not working even though there is no abs warning light lit. Replacing the bearing/stud/abs sensor assembly is moderately hard.

Failure Date: 01/12/2011

In January of this year my 2003 Buick Century began with panel lights flashing on and off at various times making the guages and speedometer impossible to read. Very expensive estimate to fix. Then in February was driving home at night and the abs light came on. Took to shop and they couldn't get it to do it. After third time had it repaired. Took whole driver side wheel assembley to get sensor $500. In March driver side window began going up and down by itself. Took it to shop and they are unable to find a problem. The car only does it when the panel lights flash on and off. Bad vibration in the car around June. Had all four tires replaced and new brakes and rotors. On August 4, 2011 vibration started again, then started a popping noise in the front end when starting and stopping. Car vibrates so bad you can not hold steering wheel at 45-50mph. This pop and vibration is now coming from front right side. Not sure what it is yet.
