Chevrolet Colorado warning lights comes on

Filed Oct 28, 2026 · Brakes · WV

I am reporting two brake-system failures involving my 2025 Chevrolet Colorado. Both involved brake-fluid leakage from the left-rear brake caliper, including a recurrence after that caliper had already been replaced under warranty. On May 27, 2026, after the truck had just been driven home, we loaded it for a camping trip with our granddaughter. When we started the vehicle to leave, multiple warning lights appeared and the truck had very little braking capability. The Chevrolet dealer documented DTC C05B0 and found that the driver's-side rear brake caliper had separated and was leaking brake fluid from the actuator side. The dealer replaced the left-rear caliper (GM part #13537065), added brake fluid, bled the system, and road-tested the vehicle. On October 19, 2026, approximately five months later, the truck displayed a "Service Parking Brake" warning. The dealer documented DTCs C060B and C2A21 and found brake fluid leaking through the left-rear caliper into the parking-brake actuator. The dealer again replaced the left-rear caliper with the same GM part #13537065 and also replaced the affected parking-brake actuator (GM part #13513581). I am concerned because the replacement caliper experienced another brake-fluid leak only five months after the first failure. The first incident resulted in very little braking capability, and we were fortunate it became apparent in our driveway rather than while driving. I am reporting this because of the serious safety risk of recurring brake-fluid leakage and diminished braking. I am aware the federal safety agency is investigating brake issues involving Chevrolet Colorado vehicles. I do not know whether these failures are related and am providing the dealer findings, DTCs and part numbers so the federal safety agency can make that determination.

While driving home multiple lights,messages and sounds came on the dashboard. I stepped on the brake and there were no brakes. I put vehicle in neutral and pumped brakes a few times. I was not traveling that fast so the vehicle stopped before I hit the person in front of me. I drove 10 mpg with my hazards on to the nearest gas station. I called Chevy service and they sent a tow truck N/C to bring to the dealer.

I purchased this truck new in March of 2024, in May I was at a Starbucks drive-thru and lost all brakes. While slowing down at the window the pedal went to the floor and my dash light up like a Christmas tree. I pulled into a parking spot and shut the truck off for about 5 minutes. When I turned the truck back on the lights were gone and the truck seemed fine, so I drove home. The next day I was picking up my kids from school when in the pickup line the same issue happened. I lost my brakes, the dash lit up, and the truck started rolling forward in the pickup line. I had to push on the brake pedal as hard as I could to make the truck stop. I called the dealer and had the truck taken there. The truck was there for several days and I was told the master cylinder and brake control module were replaced. I’m reporting this now, because I saw that this is part of a larger issue being reported and I wanted my experience memorialized to help others.

I was driving down a hill and hit my brakes and the pushed back against me and then went right to the floor with minimal braking. I got an error message on my dash that said “brake system failure- do not exceed 62 mph” Luckily it was early in the morning and nobody was in front of me. All of the lights were green and between the engine braking and the little brake power that I had I made it up the hill (about a mile) to the Chevy dealership. I got an error notification the day prior that said there was an electrical error and my check engine light came in. I drove straight to the dealership but they couldn’t do anything since it was 4:30 and later than work hours so they made me an appointment for the next day and let me go. They told me later that day that it was an issue with the master cylinder (which with some research I found that there is an active lawsuit against this issue) I was issued a loaner vehicle with a crack straight across the entire windshield (it was all they had available and I was told it would be “okay” so I’m fine with that)

He wiring harness to the 4wd kept coming on which wouldn’t allow me to ingage. Mountain Chevy citified mechanic found a chafing on the wiring harness. After filing it my truck started to light up like a Christmas tree, Stability service, trailer brake service, Locker service, Power streering service and they done turn off. Which is caused by more chafing wires that are to close to components of the engine bay getting to hot. Now my power steering turns off and when driving the truck it kicks on and make me loose control of the vehicle. Big diffect on Chevys manufacturing this vehicle. I’m not able to drive it and now they keep telling me that they don’t have the part or can’t find it.

The transmission locked up while I was on the freeway and refused to go over 40 mph. Multiple dash warning lights came on. This is after the truck has had long term transmission issues that the dealership is not repairing.

As I went around a turn (low speed), the truck lost power steering for about a half of a second. It came back online right away, but caused me to take the turn poorly. At the same time, the engine shut down and all of the lights on the dash went out. I stopped the vehicle, put it in park and restarted the vehicle. Everything then worked as if nothing was wrong. There are not any warning lights. It was as if someone simply turned off the ignition for a minute.
