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.
