The abs/traction control system has malfunctioned 3 separate times since purchase of the vehicle in 2017. The indicated fault is code c0110-04, pump motor circuit open. This fault has required the replacement of the brake control computer (gm part# 19435407) and the hydraulic control module (gm part# 25879231). The first malfunction occurred in October 2020 at 48,594 miles, the second was November 2022 at 91,621 miles with the most recent fault in August 2024 at 147,411 miles. The fault has not affected the ability to stop the vehicle, but it does render the abs/traction control system inoperative. The vehicle is a travel van with the majority miles being highway miles (very little city driving).
The contact owns a 2017 Chevrolet Express. The contact stated that while driving at approximately 35 mph, the abs inadvertently engaged, and the vehicle pulled to the left side. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the electronic brake control module assembly needed to be repaired. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 136,000.
Vehicle nearly went off road from abs prematurely activating. Abs module needed. Part number 84055065 unavailable through gm. Parked van as it is too dangerous to drive.
Part number 84055065 the abs module is defective and can not replace.

This module has now failed three times and Chevrolet has had this vehicle in one of their dealership lots since 10/5/2023 with no resolution and they've stopped communication with us.
The abs lights began coming on and off in April of 2023. My certified mechanic checked codes and found no specific trouble from the available code information. The abs lights eventually stayed on by November of 2023. Through more investigation, my mechanic determined that the abs module- c 84055066 and abs pump assembly- c 25879231 had ceased to function. He ordered the abs parts ,(manufactured in texas), and was informed that there were so many shops around the country waiting on those parts that we would have to wait months before the parts could be manufactured and delivered. My vehicle only had 40,000 miles on it when the abs lights were illuminated on the dash. The parts did finally arrive and were installed. We also had to hire a separate abs module programmer to reset the computer. The abs module and abs pump failure seams to be a completely defective system. I would hope these parts will be included in a nationwide recall. Thank you.
My company just recently purchased dozens of 2017 chevy Express vans. One of these new vans (16 miles on odometer) experienced a faulty brake booster mechanical issue which caused the brakes to engage while turning the steering wheel. The design of the brake booster integration with the power steering pump was part of the problem. This is potentially fatal design flaw if you manufacture a vehicle that would engage the brakes just by turning the steering wheel.
