THE SERVICE TECHNITION TOLD ME THAT THIS IS A COMMON PROBLEM WITH GM'S ABS SYSTEM. HE SAID I SHOULD CHECK INTO WHETHER THERE MIGHT BE A SILENT RECALL ON THE AFOREMENTIONED ABS SYSTEM THAT WOULD BE FIXED ONLY IF A CONSUMER HAD A PROBLEM. I DID NOT SEE ONE LISTED IN YOUR DATA BASE, BUT THOUGHT YOU MIGHT HAVE ACCESS TO MORE INFORMATION. THE TECH SAID IT WAS A FLAW IN THE ABS SYSTEM, NOT BECAUSE OF ANY LACK OF MAINTAINENCE OF NEGLECT. IF YOU CAN GIVE ME ANY RECALL INFO IT WOULD BE GREATLY APPRECIATED AS THE REPAIR IS VERY COSTLY FOR A PROBLEM NOT ASSOCIATED WITH NORMAL WEAR AND USAGE. THANK YOU, RANDY J. ANDERSEN
