Owner report 10119425 · 2005-05-03 (May 3, 2005)
I WOULD LIKE TO ADD MY NAME TO THE LIST OF COMPLAINTANTS IN REGARDS TO THE ANTI-LOCK BREAK PROBLEMS WITH GMC TRUCKS. THE ANTI-LOCK BREAKS ON MY 1999 GMC SIERRA WOULD INTERMITTENTLY ENGAGE FOR NO APPARENT REASON. THE DEALER SAID IT WAS DUE TO A BUILD UP OF CORROSION & CHARGED $245.00 FOR THE REPAIR. WHILE I FORTUNATELY DID HAVE ANY ACCIDENTS, I DID HAVE SEVERAL NEAR MISSES. WHETHER THIS WAS A DESIGN FLAW OR AN INTENTIONAL ATTEMPT BY GM TO GENERATE INCOME FOR THEIR DEALERS, I DON'T FEEL I SHOULD HAVE TO INCUR THE EXPENSE.
