Lemberg Law is reviewing reports of brake system failures in the 2025 Chevrolet Colorado and GMC Canyon. Owners report brake pedals dropping closer to the floor, warning lamps illuminating, and in some cases, complete loss of braking power. This same issue has also been reported in the Chevy Traverse, Buick Enclave, and GMC Acadia.
General Motors has issued a service bulletin (25-NA-064) for these trucks, but the official explanation may not cover every case. Consumers are left facing unsafe vehicles, long repair waits, and unanswered questions.
What’s Going On with Colorado & Canyon Brakes?
Owners describe a range of symptoms:
Brake pedal travel suddenly increases or goes to the floor.
Brakes feel soft or spongy, with reduced stopping power.
Dealerships often cannot fix the problem promptly due to parts backorders.
Don’t be stuck with a lemon. You have legal rights to cash, return or buyback.

What Owners Are Saying
“Brake pedal went to the floor when I applied the brakes.”
“Started the vehicle and 4 dash lights were on. Brakes felt soft and spongy, pedal nearly hit the floor.”
“…after only 400 miles on the odometer, the brake pedal became extremely soft. Warning lights came on. Dealer said part is backordered.”
“The brake system warning light illuminated and the brake pedal went to the floor.”
“Safety was at risk as the brakes were not working properly. GMC and the dealership confirmed the issue in new vehicles. Warning lights first appeared on 8/23/25, and the required part is on backorder.”
What 25-NA-064 Service Bulletin Says
In March 2025, GM issued Service Bulletin 25-NA-064 for the Colorado and Canyon. It acknowledges that some drivers may see a brake system warning lamp, feel the brake pedal travel closer to the floor, or encounter diagnostic codes P2299 and C05CC.
The bulletin attributes these problems to drivers accidentally pressing both pedals at the same time, a practice GM calls “two-foot driving.” Dealers are instructed to clear the codes if normal pedal function is confirmed and counsel customers about avoiding this habit.
However, this explanation does not align with all owner reports, many of which involve confirmed master cylinder problems and unavailable replacement parts.
What About the Traverse, Enclave, and Acadia?
The Chevrolet Traverse, Buick Enclave, and GMC Acadia are vehicles that share engineering platforms with the Colorado and Canyon. They have also been tied to brake-related problems. In late 2024, GM issued Service Update N242482170 for some 2024 and 2025 models, including the Traverse and Enclave, citing a missing internal seal in the master cylinder.
Take a look at what the TSB for the Traverse and Enclave says:
Notably, the brake master cylinder part #85779207 is associated with all of these vehicles, meaning they share a critical braking component. However, the service bulletins are not identical. For the Traverse and Enclave, the defect involved a missing seal that required master cylinder replacement. By contrast, the Colorado and Canyon bulletin (25-NA-064) points to driver behavior, not missing parts, as the cause of brake warnings and pedal travel issues.
This raises an important question: are these different problems affecting the same part, or is there a broader issue with the master cylinder across multiple GM vehicles? At this stage, it is unclear, but the overlap in parts and the consistency of owner complaints suggest a possible connection.
