Erratic operation. Indicator in side mirrors flickering with no object present. Dealer installed a new left side blind spot monitor which was tested and found to be defective, Have been waiting more than a week to have another one delivered.
At 6700 miles, the following warning lights came on: Service Trailer Brake Service ESC Service Brake Assist Adaptive Cruise control unavailable. I brought the truck to the dealer. They read the codes and found a service bulletin. “6721 found service bulletin for code C055F vehicle needs a master cylinder/booster/ebcm parts ordered” They told me it was safe to drive but I refused to drive given what I found online about this issues. The vehicle took a week to fix.
All electronic braking lights came on in truck @13040 miles dropped at dealership last Monday they believe it’s the master cylinder. Pending additional info
The Transmission jumps into 1St gear when spot at a traffic light or when parking.Back seat gap and Forward Collision Warning not functioning.
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)
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
Cruise Control I was nearly in a severe accident because of the way Chevrolet Cruise control works when I was on the highway and traffic slowed down briefly and my vehicle continued to run at the set miles and didn't slow down when I was approaching the vehicle in front of me. When I purchased the vehicle (2025 Chev Colorado) I was not informed that 'Gap' detection does not work as it does in most other modern vehicles. This feature is only available in higher end vehicles in what they call Adapter Cruise Control. My pamphlet "Getting to know your 2025 Colorado explains how to use ACC with no mention it is an option only available on higher end vehicles. I consider it a safety hazard that Cruise Control in its normal setting does not use the Gap setting as most modern vehicles do making it a safety issue, especially when you have a 2nd vehicle that works this way automatically. It was only after 2 service visits that I was told that how it works and that even though it is an option, it is not something that Chevrolet can install in my vehicle. Making it even more confusing the 'GAP' setting is available on my steering wheel controls making the user think this option is actually available when, in fact it is not. I feel Chevrolet needs to fix this potential safety issue by making the Cruise control work in the same manner other manufactures have done for several years.
Subject: Urgent Safety and Usability Concern – 2025 Chevrolet Colorado Infotainment/Instrument Cluster Failure To Whom It May Concern, I own a new 2025 Chevrolet Colorado, purchased on June 23, 2025. Just four days later, on June 27, both the infotainment system and the digital instrument cluster went completely dark, rendering the vehicle unsafe and inoperable. It has only 78 miles on it. After researching the issue, I learned this is a known problem to GM and is addressed in Service Bulletin PIT6362 released on 2 April 2025. The bulletin advises dealers not to replace hardware components as the issue stems from a software anomaly. However, there is currently no estimated timeline for a resolution. This leaves me — and presumably many others — with a an expensive investment that cannot be safely driven. Dealer is picking up the vehicle Monday June 23 but I have low confidence they know what to do. This situation is unacceptable. A total loss of vehicle instrumentation and infotainment severely compromises safety, functionality, and trust in the Chevrolet brand. It is alarming that vehicles with such a critical defect were allowed to reach customers. I am requesting the following: Immediate acknowledgment and escalation of this case Clear explanation of how GM is addressing PIT6362 Temporary or permanent remedy to restore my vehicle’s functionality Compensation or alternative transportation options while the issue persists A case number and point of contact for follow-up My question is how GM can continue to sell these defective vehicles knowing someone could, quite literally, get killed.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
