2023 Chevrolet Colorado Complaint Log

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.

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). 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.

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.

Vehicle accelerated on its own at a stop and then at highway speeds. Took it to dealership who experienced the same thing and confirmed the issue and could not find the reason why.

What component or system failed or malfunctioned, and is it available for inspection upon request? To my knowledge, which is limited on vehicle diagnosis, the engine valve body is having an issue finding a gear when starting from a stop. How was your safety or the safety of others put at risk? The vehicle engine will sputter and jolt forward and attempt to go to a higher or lower gear when approaching the stop . Has the problem been reproduced or confirmed by a dealer or independent service center?The problem is reproducible, but the dealership is stating i would need a check engine light to have it serviced or seen. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No visible alerts of fault when issue occurs or thereafter.

When you have your foot on the break engine running within about 5 mins the breaks release for a second all the light on the dashboard kick on then the breaks feel spongy, you have to then turn the truck off the computer resets check engine light will still remain but the breaks will now be functional again. When taking it to the dealer they stated there was a software recall and they reset the light called it a day.

From auto stop when engine turns back on it jerks me forward

The phone charger will not charge phones. Connects then disconnects within 5-10 seconds.

The contact owns a 2023 Chevrolet Colorado. The contact had taken the vehicle to the dealer for a routine oil change and after the vehicle was serviced, the contact was provided a multi-point vehicle inspection sheet which showed that the brake pads had received a green check mark and that the brake pads were 7-millimeters or greater on both the driver’s and passenger’s side. The next day upon start of the vehicle, the contact stated that a message "New Brake Pads Detected" question was displayed on the instrument panel. The contact selected the "No" option followed by another question to service the brake pads. The contact then stated that a "Service Brake Pad Monitoring System" message appeared on the instrument panel. The vehicle was taken back to the dealer where the dealer was informed of the messages. A mechanic inspected the vehicle and informed the contact that both the brake pads and rotors needed to be replaced. The contact was also informed that the brake pads were 2 millimeters or less, despite the contact receiving information the day prior which stated otherwise. The contact questioned the dealer about the discrepancy and was informed that the computer provided the results for the multi-point vehicle inspection. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 27,000.

I have been having intermittent issues with a warning on dash says service safety retrain system vehicle will shut off on its own doesn't want to restart Vehicle was taken to dealership for a tsb as well as the shutoff issue they had the truck 28 days said they diagnosed the truck could not duplicate my concerns I also explained the issue with display going out flickering brake lights etc, intermittent issue with btakes being hard then extremely soft, i even showed video that they can clearly hear me talking on they did not care. when I picked the truck up from dealership the mileage in was same as mileage out as noted on the paperwork and matches pictures I took They never drove the truck. On Wednesday June 4, 2025 while driving home I ended up running a stop sign and barely missing a car because truck shut off causing my brakes to not respond I was able to get it to stop just in time it was witnessed by a local law enforcement agency I showed the officer my truck would not start and pedal was unresponsive was told it had to be towed had a friend tow to my house. on Saturday June 14, 2025 while on my way to Northern Duchess Hospital the warning came on the display and vehicle shut off I was able to get it off the road could not start it had to call for someone to drive me to the hospital upon release at 5am I had to call my brother to pick me up we got truck to start after 20 mins while driving it he informed me I had no brake lights turn signals or headlight the display was black no speedometer nothing had to call friend to tow again once at my house he started checking fuses found 4 melted fuses one was ECM the others were body control module and something else this truck has 7300 miles on it the problems are getting worse last time at dealership service manager stated he wasn't wasting more than 20 minutes on diagnosing anything. Other issues are windows going down on there own climate controls coming on by itself and air coming in by top of windshield

The contact owns a 2023 Chevrolet Colorado. The contact stated that while driving through a carwash, the roof suddenly became concaved. Upon leaving the carwash the roof suddenly made a loud pop and returned to the normal position. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a structural failure with the roof. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 10.

Vehicle shaking very badly when braking. Then “Service Brake Monitor” message displays. Took it to a Chevy dealership who said my rotors were warped. Turns out many people are complaining about it on Reddit. I purchased vehicle with less than 20k miles on it and it was a Chevy certified used vehicle. I don’t feel safe driving it and Chevy will not foot the bill. This could potentially be dangerous for other drivers and my guess is the parts are defective or something other than “driving conditions” are at play. This should not be happening!

CHEVROLET COLORADO SLOWS DOWN FOR NO REASON

Forward collision braking activated for no reason and will hard brake. Has done it in the middle of an empty parking lot as well as when driving 65 MPH down the highway, twice. No major injuries happened either time other then sore necks and seatbelt marks. On 2 incidents only the driver was in the vehicle, the other incident consisted of the driver, front seat passenger and 2 children in the back seat. The vehicle has been inspected by dealership. The vehicle now has brake and router problems, which the dealership has said is from hard braking. The vehicle has a bad vibration when applying the brakes.

The right front brake caliper failed with 15747 miles. Local dealer made repairs and said the caliper was not the cause. Their cause was blaming a brake controller used in towing the vehicle. If the controller had caused the failure more than one wheel would of been effected. The three remaining wheels all showed fine and had over 7mm of brake lining remaining. The wheel effected had ZERO pad remaining. I have replaced parts in my possession for evidence.

Blind spot warning stopped working Mirror controls (unable to safely change lanes) Window controls stopped working Chevrolet has a TSB for similar but not exactly this situation, dealer won't look at it outside of warranty without charge.

When battery was beginning to get old/need replacement but vehicle would still start: 1. The power steering assist stopped working intermittently (virtually impossible to steer even at speed) 2. Power brake stopped working intermittently (very hard to get vehicle to stop) Unsafe for me, would have been very unsafe for certain without significant physical strength.

Upper radiator hose rubber grommet failing at 22k. Had a severe coolant leak coming from top radiator hose blowing back onto hot motor which could have turned into a fire quickly. I was lucky! A lot of GMC Canyons and Colorado's are all reporting the same problem around 22k miles. It is currently at Grossman Chevy Old Saybrook, CT for repair.

i have a 2023 Colorado and its only got 69,000 miles. my Crank shaft seal went out with no warnings. No dash lights or oil lights. ive read online where is this has happened to a few colorados. I had 0 oil on my dipstick and didn't have one check engine light on.

My husband and I were flat towing our vehicle on April 12, 2025. We had been traveling about 120 miles when the breaks on truck suddenly locked up, causing us to drag the vehicle for several feet before someone flagged us down and alerted us about what was happening. Our motor home is a 45' Class A, with a 525 horse power engine. If this happens while towing, we may not know it was happening until something catastrophic happened. If it happened while driving we could be seriously injured.

Was driving approx 30 mph down road when alert/light flashing for crash detection. At the same the brakes slammed on causing the wheel to pull to the right and pulling the wheel from my hands. This sudden stop was abrupt enough to leave seatbelt mark on shoulder. There was no car in front or behind me in my lane of travel. There were no people on either side of the road walking. I have had the light go off a few times with the bell but no sudden braking until an update was run last night. Which according to the Chevy recall was for ECM issue. Recall software update N242452130. I called the dealer , spoke the service manager Mike and told him what happened. He tells me him and his wife bought a 2024 Chevy Equinox that did the exact same thing. Ok, how is that supposed to make me feel better? The braking was violent and if it happened in city traffic I have no question in my mind that would have been a [XXX] crash. Every single time there is an update push there is a problem. This has been the worst. after looking up the VIN does not show part of the original recall from your agency.

When activation of the turn signal for a righthand turn. The signal will blink properly until physically completing the turn to the right, as soon as steering wheel is turned to the left to straighten the steering wheel the turn signal switch will turn off right directional signal but will then instantly activate the lefthand directional signal. Sometimes the lefthand signal will blink several times and turn off by itself. Occasionally the turn signal activation lever will need lifted up to turn it off. This does not happen every time the turn signal is used but will normally happen during a typical drive making multiple righthand turns. This is very distracting to the driver and can cause confusion to pedestrians and oncoming or trailing vehicles.

I was driving down the highway going about 75mph in the left lane. The engine quickly started going down through the gears as the engine was shutting down. I was able to get it to the right side in very heavy traffic. I had to be towed. It took a 5 day repair and replacement of the fuel pump power control module. Warranty

Transmission shifts very hard from first to second and from second to first. This occurs on the first shift of the day. I have taken the vehicle to the dealer twice and was told that, according to Chevy, this is “normal” operation.

The contact owns a 2023 Chevrolet Colorado. The contact stated while driving at an undisclosed speed, the heater did not function as intended. The vehicle was driven to the residence. The contact checked the fluids and noticed that the oil dipstick was completely dry. In addition, the contact investigated and noticed that the oil had leaked all over the surface of the oil pan. The contact stated that the oil change warning light was later illuminated. In addition, the contact stated that the failure had occurred after leaving the dealer and an unknown recall repair was performed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The contact referenced a Customer Satisfaction Program; however, the vehicle was not included. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 49,900.

The collision avoidance system quit working. The warning light was displayed on the instrument cluster but no other warnings were sounded. After taking it to the dealer for repairs, they got the light to go out by downloading another software version, but it did not fix the problem. It only removed the light. The truck still would not give a warning when approaching another vehicle too fast or get too close at certain speeds. The dealer has kept it so far a total of 12 days and have yet to fix the problem.

The contact owns a 2023 Chevrolet Colorado. The contact stated while driving approximately 5-30 MPH on several occasions, and occasionally while reversing out of a parking spot, the Forward Collision Avoidance Emergency Automatic Braking system unintendedly activated and stopped the vehicle. The contact stated that several undisclosed warning lights were illuminated. Additionally, the check engine warning light had illuminated 30-35 days after purchasing the vehicle. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the front collision wiring system, the electronic control unit, and the evaporative emissions control system needed to be replaced. The contact stated that the vehicle was possibly already repaired under NHTSA Campaign Number: 24V133000 (Electrical System, Forward Collision Avoidance); however, the failure occurred. The vehicle was taken to another dealer, Grieco Chevrolet of Delray Beach (2605 S Federal Hwy, Delray Beach, FL 33483) where it was diagnosed and determined that the front collision wiring system, the electronic control unit, and the evaporative emissions control system needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 8,300.

Fuel mileage is way lower then it should be I get 13.1 mpg and already had to replace one fuel injector

1. Other: Turn signal - when turning right with the signal activated, once you straighten the wheel, the turn signal stalk will reset to the middle but will activate the left turn signal. 2. Adaptive cruise control - For no reason the brakes will activate, there is no vehicle in front and the windshield is clean. 3. Blind spot warning - These BSW indicators will go off at random with no vehicles beside mine. This occurs more at night, but does happen during the day. When this happens at night the yellow indicator is so bright that you cannot even see what might (or is not) in your blind spot. This faulty indicator is going to get someone hurt as other drivers with the same issue might over correct.

Side object sensors go off frequently when no vehicles are there on both sides of vehicle. Additionally when passing vehicles the side object sensors only detect vehicles about 40% of the time. The side object sensors will double flash when no vehicles are there and fight me when changing lanes when lane assist is on. I have video of the false alerts and non detection incidents.

Upper radiator hoses are failing. Failed at 40k miles due to manufacturer defect of the part. Seeing owners complain about them leaking off the dealer lot and know 10+ that have had theirs fail around 30k miles.

In January of 2024, my husband was driving our 2023 Chevrolet Colorado. he was pulling onto our street driving approimately 5 mph. The vehicle suddenly stopped for no apparent reason. AT this time, we did not file a complaint because it was a minor incident and no one was hurt. We brought the vehicle into the Chevrolet dealership for a safety recall for the front cameras . On [XXX] I was driving at 830am on a highway in the fast lane. No other vehicles were near me in my direction. No one was in front of me, besides me or behind me. I was driving approximately 57mph on a very clear and calm morning. My 2023 Chevrolet Colorado came to an abrupt stop for no reason at all. No lights flashed on my dashboard, the vehicle did not shake, warning me that I was shifting lanes (because I was not), nothing came on at all. I was given zero warning that the vehicle was abruptly stopping. I have severe whiplash and have been undergoing treatment for this trauma. No police report was filed because there was no damage done to the vehicle. I immediately called, reported and turned the vehicle into the local Chevrolet dealership here in Reno, Nevada. GM's third party did a full investigative report, pulled the black box from the vehicle on December 15th, 2024 and just today, 70 days after the claim, GM informed us that they want to buy the vehicle back. GM is claiming "what happened is consistent with the unwanted or undesired automatic emergency braking system failing." This is the only communication we have had with GM thus far.
