2016 Chevrolet Colorado Brakes

Operator reported that under braking, they lost all power assist to the brake pedal and brake pedal was extremely hard to push. This resulted in extended stopping distance and difficulty slowing the vehicle down. It was found that the vacuum pump had failed. We are a large utility fleet, and this issue has occurred a number of times to our Chevrolet Colorado/GMC Canyon vehicles and we deem this a safety issue. These incidents have been reported to the OEM and we recently received the attached reply, "We submitted a “Speak up for Safety Campaign” to our internal quality team for review. These reviews are conducted to determine if there is a manufacturing or design defect that could impact quality. After review, the case was closed with no action to be taken." The operators receive no warning prior to the failure.

The brake pedal suddenly became very stiff with no warning while driving at highway speeds. Braking was very difficult and required me to swerve into another lane to not impact a car and run a red light. I managed to stop afterwards. This was caused by the cam driven vacuum pump failing. No warning of any kind was given.

Vacuum pump failed and developed a tear almost leading to an accident. Now part of the pump system broke into motor leading to potential engine failure.

During a preventative maintenance inspection, the mechanic found oil coming from the vacuum pump. Due to the number of failed vacuum pumps the fleet has been experiencing, the mechanic decided to replace the pump in order to avoid a vacuum pump failure during operations.

The contact owns a 2016 Chevrolet Colorado. The contact stated that while backing out of a parking space at a very slow speed, the braking system suddenly malfunctioned and erroneously released causing the vehicle to surge backward and crash into a second parked vehicle.

THE VEHICLE STARTED ROLLING BACK WITH MY FOOT STILL ON THE BRAKE AND I HAD TO PRESS ON THE BRAKES EXTREMELY HARD TO STOP THE VEHICLE FROM MOVING. THE VEHICLE STRUGGLED TO STOP, SKID AND THEN STOPPED. I PUT THE VEHICLE IN DRIVE AND IT DID THE SAME THING. I LIVE ACROSS THE STREET FROM PEP BOYS SO I CAUTIOUSLY DROVE IT TO PEP BOYS AND THEY FOUND THE BRAKE BOOSTER VACUUM HOSE WAS UNPLUGGED. THEY RECONNECTED IT, BUT NOW I'M SCARED FOR MY SAFETY FROM THE POSSIBILITY OF THE HOSE DISCONNECTING WHILE DRIVING AND CAUSING AN ACCIDENT. THEY MENTIONED THE BRAKE BOOSTER HAS TO BE REPLACED, BUT THEY ARE CONFUSED AS TO WHY IT'S HAPPENING BECAUSE MY VEHICLE IS FAIRLY NEW.

APPROACHING AN INTERSECTION AND OBSERVED A YELLOW LIGHT. I WAS TRAVELING 35MPH AS POSTED AND APPLIED THE BRAKES ONLY TO HAVE THE PEDAL GO ALL THE WAY DOWN TO THE FIRE WALL. THE TRUCK HAD NO BRAKING POWER AND ONLY SLOWED TO ABOUT 15MPG AFTER APPLYING FOR ROUGHLY 40-50 YARDS. I ENDED UP RUNNING INTO THE INTERSECTION COLLIDED WITH ANOTHER VEHICLE THAT PROCEEDED ON GREEN.
