For approx. 4 months I would go to get into my Trailblazer and the vehicle would be dead. Would not start unless I had it jumped. It would go 2 weeks with no problem then out of the blue, not work. I had the battery changed 2 times, alternator, starter checked with no problem. Finally after the last time, I had the alternator people come and get it and they checked it out for 2 days. The ABS system is what came up. I had to have it taken to the dealer that I purchased it from (I have only had this vehicle purchased used for a year and couple of months-vehicle is only 4 years old now) and it is the ABS module costing me $1150 to be fixed. Dealer states that it stays on after vehicle is turned off and running my battery.
