Chevrolet Trailblazer abs comes on

Filed Oct 3, 2026 · Brakes, Driver assistance · GA

ABS brake system failed causing breaking to surge and not work correctly and not stop like it should resulting in having to have the ABS module and pump replaced at an extreme cost. With no clear cause and using the same parts this is likely to happen again. Had to be taken to the dealer because it required special software and bleeding procedure that a local shop wasn't able to do. The dealership stated that this should probably be covered soon in a recall that this was a known problem and they have had quite a few issues with this ABS pump assembly.

The ABS system in this vehicle flashes warnings at quick restarts and while holding the brake down, it has no “sponge” when this happens. The brakes squeal constantly. I’ve had them inspected at every single maintenance and there can be no flaw found. When driving on the interstate, the engine is very “jerky” almost like the transmission can’t keep up with the speed of 70-80mph (not always, but it is noticeable when it happens). At first I didn’t think much of it but with the mass recall of chevys identified, I believe it needs to go on record - particularly about the brakes.

I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.

The contact owns a 2022 Chevrolet Trailblazer. The contact stated while driving approximately 62 MPH, the vehicle started shaking abnormally.

The ABS and stability control systems crash without warning. Randomly on a trip the check engine light randomly comes on without warning and immediately my break system stops being effective. I have to put full force on the brake pedal to start breaking the vehicle and coming to a stop becomes difficult. This puts my life as well as others at risk as I would not be able to break on time. The problem immediately goes away after turning the car off and turning it back on leading me to believe it’s simply a computer problem. The service provider Chevrolet has not reproduced or confirmed the issue to my knowledge. No warning lights come on prior to the issue nor does the check engine line persist after being turned off and on again.

There's a problem after braking which causes a few second delay when accelerating from a slow speed, supposedly part of the stabilitrak/ABS system caused by a faulty sensor. I have almost had a couple of accidents because of this when waiting to turn in a left turn lane.

Stabilitrak light comes on intermittently for no apparent reason. Have had brake fluid, brake pads, rotors, sensors and tires replaced. Traction control and ABS checked; all is good. No cel code relating to this issue. Traction control off button doesn?t work once light appears. There is no difference in driving when light is on. Still haven?t figured out what causes it. Battery, power cords, and alternator have both had to be replaced do to issues with the voltage outputs. Now to replace fuse box and ECM due to more voltage output issues. Cel has had no indications of an ECM, fuse box, alternator, or battery problem until they were beyond repair (this also happened with other transfer case leak, loss of reverse gear, and front differential leak) . Cel comes and goes by itself at anytime with no difference in drivability or conditions. Each time it reappeared it?s thrown different sensors and/or circuits failing or high/low voltages including o2, maf, tps, evap system, wheel speed, fuel pressure, oil pressure, steering wheel, gas and brake pedal position, air bag impact, just to name a few. My car has recently started going into limp mode at random due to this electrical issue. Only remedy for this problem is disconnecting the wiring harness and allowing the fuse box and ECM to cool down. And finally, my oil filler tube seal broke and oil was spitting out into engine bay. Coincidentally, my pcv valve tube had also broken, and the tube was hanging loose right in front of the oil filler tube. As a result, pcv tubing sucked up a large amount of oil into the air intake; with no check engine light illumination indicating any problems during the time of failure. My air intake system is nearly ruined (not to mention the $$$ I shelled out in oil) and the wear down on parts has been detrimental to the life of the engine. This car is nothing but a cash cow for gm.

I have had my SUV since 2011 have had no problems with it until about feb. 25,2019. I had my brakes replaced ftont and back along with the rotors. A week after that I was driving on the highway come up to a red light was slowing down and when I got to 10 MPH it started to paulsate and wasn't for sure if I was going to stop completely. I finally did. I took it back to my mechanic he checked the ABS to see if the wheels were spinning at the same speed and they were. When I go down my driveway whick is a hill I'm not for sure if it's going to fully stop or go on out in the road, we are on a blind curve and it's rather scaring. Also I have a problem with the stablility and track light coming on and staying on, I just restart my SUV again for it to go off. It's both of the lights on the track and stablitity. My driver side seat belt is frilly on one side and getting thinner.
