2023 Chevrolet Colorado

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.

The contact is a law enforcement officer calling on behalf of the owner of a 2023 Chevrolet Colorado. The contact stated that while the driver was driving at approximately 20 MPH, the vehicle collided with a telephone pole head-on. The contact sustained a head injury and received medical attention. A police report was filed. The reporting officer noted that none of the air bags had deployed during the crash. The vehicle was not towed. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was not available.

Coolant leak, upper radiator hose, TSB issued PIT6494A over $500 repair. Not covered under any warranty.

Smell gas the night before. Today, March-20-2026, after driving car for few miles, it came to a complete stop on high way I-95. Large amount of fuel was leaking from fuel hose attached to fuel tank. Vehicle was unsafe to drive.Vehicle was towed to car shop. Damaged part will be determined after fuel tank removal. Vehicle is at Franco Auto Repair in Dania Beach, Florida

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 20K miles). You can check the Colorado Chevy forum, youtube, etc., et al, and find plenty of instances where this has failed. As this is the cooling system, it can cause the engine to overheat and potentially ruin the engine. The flaw seems to be an engineering issue with the rubber seal they use (instead of a high quality o-ring) to seal the upper hose to the radiator. Additionally, since this can cause engine failure it should be addressed immediately. Instead, my local Chevy dealer, since its not a recall item, said they could schedule a time next week for me to LEAVE the truck and then they would get to it in 7-10 days. This is extremely unfair to the consumer who depends on these vehicles. This should absolutely be a recall item. You can find 1000's of examples online and if you can pull GM repair data, I'm sure you'll find 1000's more.

Radiator hose near failure, lose of coolant could be catastrophic. Upper Radiator hose quick disconnect O-ring inside failed.

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

Upper radiator hose leak.

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.

Since Friday, February 23rd 2026 when my 2023 Chevy Colorado first start blowing oil out of the oil pan. almost 5 qts total was lost when it arrived at the dealership. Truck was out of service from Friday until the following Wednesday, January 28th. The truck was picked up and taken on a drive out to (January 29th, 2026) Waverly, KS from my hometown of Prairie Village, KS about 70 miles. On the way back home the truck went into safe mode at highway speeds. Lost all acceleration and barely made it off the side of the road before getting hit. Truck went back to dealership after being towed 70 miles. Where it was kept until Friday, February 6th. During this time at the dealership, they thought the problem was fixed, where again blew out all the oil while driving. Finally received the truck back. Check engine lights were still on but truck was holding oil and driving decent. Truck was doing fine until Monday February 16th. I was at a job and was driving home to finish the day. Again on the highway at highway speeds, truck goes into safe mode and limp it to gas station to again be empty on oil. It is still sitting there. Just last January the truck needed a new Transmission at 48,000 miles and at the same time a wirinig harness for the back-up camera needed replaced. Alot of things have been going wrong with this truck to be so new. It has cost me alot of out of pocket expenses.

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 37K miles).

The upper radiator hose and gasket on numerous Colorado and Canyon trucks have failed prematurely. Mine has failed at 31k miles. Radiator hose leaks can cause engine overheating and failures while on roadways. Additional issues of leaking coolant on roadways and into the environment. Vehicle is scheduled to be viewed by dealership. Symptom which lead to diagnosing problems included rushing fluid sounds as air was introduced to the coolant line as well as an observable leak on the driver side where the radiator hose connects to the radiator.

Driving on expressway step on brakes to slow down, brakes become spongy and will not stop quickly, only slow down, engine decelarates to 60 mph. This has now happened 7 times in one and a half years

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)

COMPONENT FAILURE: Body Control Module causing systematic electrical failures: door locks, power windows, window regulators, four-wheel drive transfer case display. Components intact, available for inspection. SAFETY RISK: Door locks malfunction preventing emergency exit. Power windows fail affecting communication/egress. 4WD display fault (yellow AUTO vs white) indicates transfer case control issues affecting traction in mountain winter driving at 10,000ft elevation. Unpredictable electrical failures create safety risk during remote travel. DEALER CONFIRMATION: Approximately 20 dealer visits. Each time: scan codes, test drive, "no fault found." Problem temporarily clears via battery disconnect/reconnect, proving electrical fault not mechanical. Dealer cannot diagnose root cause, hasn't performed systematic electrical testing. MANUFACTURER INSPECTION: None despite repeated failures. WARNING SYMPTOMS: Intermittent: door ajar warnings, power window/lock failures, 4WD indicator yellow, various warning lights. All symptoms simultaneously resolve after battery disconnect/reconnect, indicating BCM or power distribution fault. Pattern repeats with increasing frequency. CRITICAL: Research shows multiple 2023 Colorado owners report identical patterns - intermittent multi-system failures resolving via battery reset. Indicates systematic 2023 model year defect, likely BCM firmware/hardware issue. Problem occurs unpredictably, clears during dealer transport. Request GM engineering data logging during normal operation.

I have experienced brake failure twice while driving my 2023 Chevrolet Colorado. When the failure occurs, the dashboard displays multiple warnings, including “Service Traction Control,” “Service Power Steering Drive With Care,” and “No Assist Soon.” When these messages appear, the steering becomes extremely stiff, the brakes lose stopping power, and the vehicle becomes very difficult to control. The first incident happened around April 2024, and the dealer performed a software update. The issue happened again around October 2024 at approximately 24,000 miles. The vehicle is primarily used on highways and has no modifications. This is a serious safety concern. The combination of brake loss and power steering failure could result in loss of control, crash, injury, or death. There was no warning before the failures occurred. The dealer cannot confirm a permanent fix. This problem needs to be investigated for a potential recall. This vehicle is now unsafe and unreliable. I refuse to transport my family in it. I am seeking a full refund/buyback, as multiple safety system failures are unacceptable and dangerous.

Roof dents when going through car wash and blowers will dent the roof. GM has a service bulletin on this lbulletin number 23-NA-209 DATED March 24. Bulletin says that all Colorados built before Feb 3rd 2025 should be repaired and gives a part list and how to fix it 9 pages long. BUT GM says my vin number is not showing a recall and will not fix it My Colorado HAS NO DAMAGE BECAUSE I HAVENT PUT IT THROUTH A CAR WASH TRYING TO GET THEM TO FIX WITHOUT PUTTING A DENT IN IT. THE FIX IS PUTTING SUPPORTS IN THE ROOF TO REINFORCE IT.

Intermittent break failure service dealer could not duplicate contacted GMC they say call back if it happens again.

The right turn signal will click for a left turn after completing its right turn without physically pressing the turn signal. Has happened since buying vehicle, continues to happen now. Turn signal was replaced by dealership, problem not resolved. Have reconfirmed problem with dealership service manager as well as video evidence of issue. Issue happens at all speeds, idle to freeway speeds.
