My 2003 Buick Rendezvous has a abs problem where it engages completely on its own whenever the outside temp is more than 50 degrees. While driving, I hear a humming noise at various time during my drive and when I push the brakes the abs system is activated and the petal pulses and a grinding noise is heard. Although, the abs light does not light up on my instrument panel. This is constant throughout the months of may through October since the temp is above 50 degrees during the day. I have had both front hub assemblies and wire harness replaced with no avail. Then, during the winter months, the awd system disables anytime I have tire(s) spinning. I have talked to several mechanics and not one seem to have any idea what can be wrong. I have researched online finding an alarming amount of people with the same problem concerning their Rendezvous, but no solution.
2003 Buick Rendezvous. Sporadic brake noise and braking problems with accompanying warning messages required service assessment. Diagnosis was defective hub and bearing assembly on right rear. Repaired at cost of $340. 00. Six hundred miles later, same problem, same repair required. Now, three weeks later, I have the same problem. Each time, it seems a different wheel is involved. I have begun investigating and it appears Buick has had a significant problem with their hub and bearing assemblies. It seems a recall is in order.
