Brake Sensor problems of the 2005 Chevrolet Trailblazer

This vehicle has had constant braking issues. From continual rotor replacements to regular pad replacements. The brake pedal has never been constant with regard to pressure and has always been"soft" when coming to a stop. The last 25 feet or so there is a vibration, hum, and when finally stopped, the pedal sinks another 1/2 inch or so like it sighs of relief. This makes it difficult to judge appropriate braking distances and lacks confidence in emergency situations. We took it to grossman Chevrolet where it was purchased in old saybrook CT. We were told theres nothing wrong and our driving style is to blame. That we were braking too hard and causing the rotors to warp. There is a fault in the abs sensor system and gm has done nothing to assist owners. It is a known issue. This must be recalled or repaired at gm expense. I will not pay a stealership any more money to fix an issue that is an engineering fault.

When we first got the truck my husband and I were driving at about 55 mph and went to brake suddenly and the truck would not stop, it made a grinding sound and I had to pump the brakes a few times before the finally stopped. After that we called the dealer and they said it is because the truck was new. . It is 2014 and still have the truck and still does the same thing. Lasst winter I had a bad incident where the car did the samed thing and almost got into a very bad accident, thank god I was able walk away with no injuries. We have reached out to the dealer numerous of times to say that there is something wrong with the brake mechanism of the truck and they say that there are no recalls on this vehicle. I dont know why the dealer just wont take the truck for a test drive and see why we are so concerned. They want to charge us almost $300 to run a diagnostics on the truck which we refuse to pay for. We took the car to a midas and the mechanic said that these trucks are known for having bad brake sensors, which makes all the sense. I just dont get it. . With all of the complaints that were given before the lastest electrical short recall they had, you would think they would take customers serioulsy before any more deaths occur, because of negligance.
