2023 Chevrolet Colorado driver assistance problems

Filed Sep 21, 2026 · Brakes, Driver assistance · UT

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 Chevrolet Colorado ZR2 cannot receive over‑the‑air (OTA) software updates because the gateway module is still running outdated firmware (XXX.mnf). General Motors issued Service Update XXX to correct this defect by performing a vehicle‑wide programming update. However, GM’s system incorrectly shows the bulletin as “closed” for my VIN even though the gateway module was never updated. The truck was sold to me by Tyrell Chevrolet in [XXX] with this safety‑related service update not completed properly. The dealership has confirmed they cannot perform the required update because GM’s system will not authorize it until the bulletin is reopened. GM corporate has been contacted multiple times, but after several days they have not reopened the bulletin or provided a resolution. Because the gateway module remains on outdated firmware, the vehicle cannot receive critical OTA updates related to safety, diagnostics, and module stability. This condition has been reported by other 2023 Colorado owners and has previously been associated with battery‑drain issues caused by software modules failing to sleep properly. GM has acknowledged the defect by issuing Service Update XXX, but they are refusing to reopen the update for my VIN despite the incomplete firmware and the vehicle’s inability to receive OTA updates. I am filing this complaint so the defect and GM’s refusal to correct it are formally documented. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The blind spot indicator on my truck activates randomly without any vehicle present, and I reported this issue immediately after purchasing it. Despite bringing the truck to Boyd Chevrolet in Henderson, NC multiple times, I am repeatedly told they “can’t duplicate the problem” and therefore cannot repair it. Their only explanation has been that “maybe a future software update will fix it.” No components have ever been replaced to rule out a defective part, and I have no indication that Boyd Chevrolet has escalated the issue to Chevrolet, or anyone else, for further guidance. After nearly three years and 30,000 miles, the problem remains completely unaddressed while my warranty is nearing expiration. This is not a minor inconvenience — it is a serious safety hazard. On several occasions, I have begun changing lanes only for the blind spot indicator to suddenly illuminate, causing me to jerk the wheel to avoid a car that isn’t there. The unexpected false alerts create a dangerous overreaction that puts me and others at risk. I want my truck properly diagnosed and repaired, but I have been unable to find a solution through the dealership. I have detailed service records documenting every visit and every time I reported this issue. At this point, I need meaningful action taken to resolve this ongoing safety concern.

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.

The automated emergency breaking system has been triggered unintentionally twice traveling at speeds of 50 miles per hour. There was no vehicle or object that entered our path. We were traveling behind cars at least three car lengths behind that remained at the same speed. Had there been vehicles behind us, we would have been rear ended at high speeds as the truck came to almost a complete stop on its own immediately.

Blind spot monitoring system consistently malfunctions, illuminating the driver mirror warning light when no other vehicles are present. It occurs more frequently after dark, which flickers the bright light continuously, or leaves it on constantly, creating a significant distraction and mistrust of the systems reliability. Dealer had no recommendation for fix.

Traveling approximately 45 mph on a main road and brakes automatically engaged causing vehicle to abruptly stop. This due to faulty Automatic Emergency Braking system that has allegedly already been repaired with a software update. My child and I were in the vehicle and had another vehicle been directly behind us or even oncoming we would have likely been involved in a collision. There was no warning that came on other than the red flashing lights and beeping that engaged the same time as the automatic braking. I will likely have to go to seek medical care for soreness in my neck and back from the jarring of my body from the abrupt stop. Waiting to hear if daughter is feeling any pain as well, as mine onset through the day after the incident.

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

Radiator inlet hose leaked which caused low coolant. Check light alerted. Replace the hose. Parts are on backorder. Also had a recall on the emergency brake assist. I took this in for the recall however the alert assist still goes off.
