Three problems related to brake electric antilock have been reported for the 1998 Buick Regal. The most recently reported issues are listed below.
The vehicle experiences intermittent noise coming from front end when vehicle is backing up. The consumer stated that the noise appeared to be coming from the abs. During a test drive the technician also heard the noise but was unable to identify the problem. The dealer contacted the regional service technician who indicated that the abs noise was normal.
Vehicle has shakes severely when brakes are applied. Could cause loss of control of vehicle and crash.
Front rotors were warped at 25,000 miles and required surfacing. The second dealer surfaced rotors correctly. When the rotors are slightly warped the abs cycled every time the brakes are applied increasing braking distance. Upon parking the car on a slight grade and restarting the abs cycles. With foot on the brake upon letting up to back out the abs cycles and releases the brakes. The steeper the slope the farther you roll without brakes. More than eight feet in some instances before the brakes reapply. The dealer and Buick service state that this is normal.
