2023 Chevrolet Colorado service brakes problems

“I took my truck in to the dealership for a recall on the faulty radiator hose and told them that I had a break sensor warning pop up on my screen. Today, I was informed that the break pads and sensor are damaged, the pads are worn out and that the rotors are damaged and need turned. I barely have 20,000 miles on this truck that I bought brand new! I was then informed that the warranty expired on the breaks at 7500 miles and that I need to pay about $600 to have the breaks fixed! I paid almost $50,000 for this truck and the breaks are already bad!!!??? I did a search online and found that many, many people are having this very issue, and in fact my own brother got rid of his 2023 Colorado for a break issue. GM is ignoring a real safety issue here! Just like they ignored the faulty radiator hose seal issue that I took this truck back in for 3 times, (before GM sent a recall letter out for-they finally admitted there was a problem!) Car forums are loaded with people complaining about the breaks and all are saying GM is ignoring the problem. I tried calling GM to complain and was told "sorry, nothing we can do". This is BS. They need to stand behind their product…”

“While driving, the vehicles internal computer system seized, completely shutting down and restarting itself over the course of 30 seconds. During and after this event, the brakes, power steering, and restraint system all became inoperable. Brakes failed to engage and power steering did not function. The issue resolved itself after turning the vehicle completely off and back on again. Brakes, power steering, and the restraint system have operated off and on over the past week since the event happened”

“After shifting to drive the vehicle had no brakes. A week or so earlier the check engine light came on. Messages on the screen said brake system failure along with other messages. Took to dealership, an update was installed. Last Wednesday engine light reappeared with the same messages but didn’t have time to return it to the dealership so parked it until today. Today was the brake failure. Returned to dealership, they replaced the battery and said the brake issue is fixed. I’m not convinced this fixed the issue and believe this could get someone seriously injured or killed.”

“My 2023 Chevy Colorado developed a rear brake squeal when backing up at approximately 20,000 miles. The dealer found nothing wrong at my next appointment. By 30,000 miles, the rear pads and rotors required replacement, at partial cost to me. The new rear brakes are already squealing again after just a few thousand miles. This isn't an isolated issue. A Chevy Colorado forum I follow has documented multiple owners experiencing the same pattern: rear brake squealing beginning around 20,000 miles, followed by premature pad and rotor failure shortly after. Notably, front brake wear is normal across all reported cases, including my own, pointing directly to a rear-specific defect rather than general driving habits or conditions. The rear brakes on the 2023 Chevy Colorado appear to be failing well ahead of any reasonable service interval, and the consistency of this pattern across multiple owners strongly suggests a systemic problem.”

“My truck has used automatic emergency braking multiple times while driving at variable speeds with no obstacles or vehicles in front of me causing whiplash and further damage to my neck that has 5 budging discs. Since I’m only allowed to add a specific mileage and speed below, I’ll note here that it’s happened since I purchased the truck with roughly 35000 miles on it to the current mileage of 44000 and between speeds of 30mph-75mph.”

“Recall was performed on truck about a year ago for the pedestrian collision automatic braking. Today the truck locked up the brakes in traffic and there wasn’t a pedestrian in sight. I believe the recall didnt truly fix the issue, as it has given false alerts before without applying the brakes”
