Problem was fixed. This is obviously a safety issue. Gm has already recalled 99 - 2002 (mine is a 2003) Suburbans for this. Mechanic indicated that abs sensors were badly corroded (presumably) from salt getting into contact with the sensor. Mechanic also indicated that he has fixed this in *many* Suburbans and in many cases that came after owners had unsuccessfully tried to get dealers to fix the issue. Mechanic said dealers were replacing the abs computer, at a cost of thousands of dollars, and problem still wasn't fixed.
