What owners say
For about two months my 2016 Chevy Colorado has been having a random power steering and stabilitrak issue message popping up. There’s no clear reason why this happens as I can drive my truck for days/weeks and it was suddenly lose power steering. When this happens it is a serious safety issue as I can be on the highway driving fine and my power steering will just suddenly stop working. Normally, I pull over and turn my truck off for 30 seconds to 1 minute and turn it back on and the issue will go away. I had two separate scans performed on the truck and both scans showed no “current” errors but pulled up past error codes of problems with ABS system and “low voltage.” I do not drive my truck roughly and most miles are simple roads or straight highways. No rough roads or heavy water/snow/mud. I have looked online and multiple threads from other drivers of GMC Canyons around 2015/2016 and trucks like mine who have had similar issues and the Canyon has recalls concerning this but I currently have none for the Chevy Colorado so I wanted to report this issue, especially for the safety reason. I believe if my wife was driving my truck on the highway and this happened she may not be strong enough to pull off and/or turn the truck if she had needed to since it is very difficult to turn the wheel when this error occurs.
Lose his power steering while driving down the road. System says needs work on ABS when you hit a bump the radio changes itself. The anti-theft is on when key is in ignition and going down the road it's saying it's theft mode service engine light is on even after servicing the engine
The vehicle is registered to me; my mother was the driver at the time of the failure. At ~2,963 miles, the truck developed intermittent check engine and ABS warning lights. The dealer pulled DTC C058A (brake system control module) and P25A2. Per GM bulletin PIT6012A, the battery was replaced and a brake plunger motor sensor learn was performed. The same codes returned within weeks. The dealer then diagnosed internal failure of the brake master cylinder and reservoir, documented the vehicle as "unsafe to drive," and replaced both under warranty. The truck sat at the dealer over six weeks due to a nationwide parts backorder. Repairs were completed April 4, 2025. On May 2, 2025, at ~6,500 miles, the driver was traveling downhill on a city street in the rain at roughly 20 mph. The brake pedal suddenly became hard and resistant. Despite full-force pedal pressure, the vehicle could not be stopped. It entered an intersection, struck another vehicle, then struck a tree. Front and side airbags deployed; the vehicle was totaled. The driver sustained a concussion, broken finger, and severe back and knee injuries, was transported by ambulance, and required months of concussion treatment including vestibular therapy. The hard, resistant pedal is consistent with failure of the electronic brake boost assist (eBoost) system, leaving only unassisted hydraulic braking (roughly 4–5x normal pedal force). This matches other owner reports and the class action in Barron et al. v. GM LLC, which cites defective master cylinders with a missing internal cartridge seal on the same platform. The vehicle is no longer available for inspection. The driver was concussed with significant short-term memory loss at the scene; statements in the police report may not reflect the mechanical failure. Full police report available on request (exceeds 10 MB limit).
Vehicle: 2023 Chevrolet Colorado Crew Cab 4WD, VIN: [XXX] , mileage: 52,877. Recurrent failure in the cooling system and engine/transmission, affecting safety and use. Check Engine Light comes on and off intermittently, code P30C5 (Coolant Flow Low). The coolant pump was replaced under warranty on March 20, 2025, at Leson Chevrolet (Harvey, LA) with 26,621 miles (attached invoice), but the same issue persists 9 months later with "Engine and Transmission System" alert in myChevrolet app. This is the 5th failed repair for the same defect since purchase (August 2023). Previous repairs include transmission wiring/sensor (January 2024) and Traction Control/ABS (December 2023). The vehicle is unsafe for daily 100-mile commute. Request investigation for potential recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle: 2023 Chevrolet Colorado Trail Boss Mileage: Approximately 14,000 miles I am submitting this complaint because the ABS braking system on my vehicle activates unexpectedly and causes a temporary loss of braking when driving over uneven pavement. When braking over potholes, bumps, or rough road surfaces at low to moderate speeds, the ABS system engages even though traction is available. When this happens, brake pressure is reduced to the point where the vehicle does not slow as expected. The ABS warning indicator flashes briefly, and there is a noticeable delay before normal braking resumes. This behavior has occurred multiple times in normal driving conditions on city streets, not during panic stops or slippery conditions. The issue feels most pronounced when approaching intersections or slowing in traffic over broken pavement, where consistent braking is critical. The momentary reduction in braking force significantly increases stopping distance and creates a safety concern. The vehicle has low mileage, has not been modified, and is maintained as delivered from the manufacturer. There are no warning lights remaining on after the event, and the issue appears to be related to ABS calibration rather than driver input or road conditions. This does not feel like normal ABS operation and gives the impression that braking is interrupted at the exact moment it is needed. Given the frequency and repeatability of the issue, I believe this represents a potential safety defect that could contribute to a collision, particularly in urban driving environments with uneven road surfaces. I am submitting this complaint to document the issue and to request that the ABS braking behavior on this vehicle be reviewed for safety.
On the day of purchase, while driving on a freeway, the vehicle would not accelerate. The RPM's went up, the engine revved, but the vehicle acted as if it was in neutral. These vehicles will not accelerate if they think the brake pedal is also being pressed. The brake was not being depressed. As I was pulling the vehicle to the side of the road, suddenly it allowed me to accelerate again, and I continued with no further issues. One week later, with fewer than 200 miles on the vehicle, upon starting the dashboard showed alerts to Service ESC, Service Brake Assist, Service Trailer Brake System. The ABS and Traction Control lights also came on. These are all systems designed to prevent loss of control, and all failed without warning. A dealer service center diagnosed this as a known problem with a faulty master cylinder, on several models built over a period of several months.
Many warning lights are on for traction control, abs , brakes service ESC, trailer braking and the adaptive cruise control system is not working, it was reported to the dealer, they checked it said bad battery, they coded it out said it is fine now on 9/5/25. It’s back at the dealer with all the same warnings on again
This truck was purchased May 2025 and currently has 2600 miles. Without any warning the brake light and ABS warning lights came on along with messages reading Brake Assist,ESC, and Trailer Brake require service. I took my truck in to a Chevrolet dealer on Aug 18, 2025 for inspection of issue. I was informed the Master Cylinder has failed and because this was a “SAFETY” issue I could not take drive my truck and they would not allow me to remove the vehicle from their lot. I understand there has been many people with this same issue. Why has a recall not been issued? Why is Chevrolet still selling these trucks? This needs to be addressed ASAP to save lives.
Started the vehicle and 4 dash lights were on. The ABS light, the forward collision system light, the BRAKE light, and the traction control light. The vehicle was taken to a dealership and we have been notified by the dealer that it is a Master Brake Cylinder failure. The part is on national backorder with no ETA. Luckily, it did not fail while driving, but could've been tragic. This vehicle is brand new and belongs to my 16 year old. This is a known issue on the Colorado, Traverse, and possibly other models. However, I have yet to find a recall or TSB. Brake cylinders are FAILING in brand new vehicles and GM needs to address it.
