Three problems related to brake light on have been reported for the 2015 Chevrolet Suburban. The most recently reported issues are listed below.
In late December 2018, the brakes began to exhibit signs that they needed to be replaced. Before we could get the car to the dealership for a brake inspection in early January 2019 due to the holidays, the brakes actually totally failed to operate at slower speeds (below 30 mph). Even when "standing on the brake pedal" with both feet the vehicle would not stop. This happened several times especially at slow speeds while backing out of a driveway or going through a drive-thru. The "brake assist light" also came on during several of these events. Also, a "grinding" noise occurred. This may have been the anti-lock brake system activating. The vehicle is now at the Chevrolet dealership in our area waiting on repairs that we are concerned will not correct the problem and prevent it from occurring again. This concern is due to the fact, through our research, that there are pending lawsuits against gm and gm itself has issued several "service bulletins" addressing this issue, but will not initiate a recall of the affected vehicles. They won't even offer any reasonable solution to truly prevent future brake failure even after their recommended repairs are completed and paid for.
While driving down the highway the steering locks up the brakes go to the floor and the stabilitrac light and brake light comes on! we had at martin Chevrolet in cleveland texas in February of 2017 and it's back there now! they replaced the fuse box last time and they can't figure out what it is now!.
While driving on a highway, the abs & brake warning lights eliminated. It was determined that the issue was the ebcm brake controller module that had failed causing the associated abs brake pump to run continuously, thus destroying it. The module and pump are located on the frame approx. Below the drivers set. Dealer's estimated cost to repair $1,200. At the time of the incident the ebcm module was on back order and the dealer could not correct the issue. I had to buy a refurbished module and a new pump to solve the issue.
