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.

Gm ignition switch problems/recall. On 07/18/2014 I took my 2005 chevrolet trailblazer (32,262 mi.) in for service to fix/replace parts: faulty ignition switch. Today, 06/02/2017, my trailblazer (35,193 mi.) is still having the same problem. A faulty ignition switch which is causing ABS and parking brakes lights to come on and stay on, the blower for air/vent will not work and since these parts are all connected electrically, I once again have to replace the faulty ignition switch. I was never reimbursed for the first recall. Please look into this matter. I would hate to get rid of a perfectly good vehicle, that has held up all of this time, I only have 35,200 miles on this 2005 chevrolet trailblazer. Will the ignition switch keep failing on this vehicle? Thank you.

When driving vehicle both left and right low beam headlights go out. The first time it happened was when I was driving long distance in the dark. Had to drive with my high beams on for the rest of the trip. There is no specific time frame, but generally it happens anywhere from 10- 30 minutes of driving. I suspect it is heat related. I have changed the headlight relay #46, bit it only fixed the problem for a week. Again the lights will go out after driving several minutes. I noticed there is a recall for a similar issue on the 2006 chevy trailblazer. Could this be the same problem with my vehicle. There are also multiple forums explaining the same exact issue with early 2000 model trailblazers. This issue happened approx 6 months ago. Last week we ran into another problem. Our ABS light comes on periodically. Like the headlights going out, the ABS light comes on after driving the vehicle for a certain amount of time anywhere from 10 minutes to 30 minutes. Again, I feel it electrical components/wiring is overheating and causing these issues. I feel there should be a safety recall for this this issue as it is affecting hundreds of customers USA wide.

Turned vehicle on and found A/C blower not working and ABS and brake light come on. Blower will come on intermittently when the bas / brake light goes out. I am concerned that if there is a short in the system there could be a fire. Chevrolet should be taking care of this concern for the owners.
