Electrical System Problems of Chevrolet Colorado - part 1

Issue 1: cooling fan remained on after engine shutdown component or system involved: engine cooling system and fan control system, including the radiator cooling fan, fan relay, coolant temperature sensor, wiring, or engine control module (ecm). The vehicle is available for inspection upon request. What happened: after turning off the engine, the radiator cooling fan remained running continuously for approximately five minutes and would not shut off as expected. No warning light, message, or other dashboard indication appeared before or during the event. This was unusual behavior compared with normal operation. Safety risk: the unexpected fan operation created concern that the cooling system was malfunctioning and that the vehicle could overheat, experience an electrical problem, or become unreliable while driving. A cooling system or electrical failure while in traffic could put me and other drivers at risk. Reproduction or confirmation: the issue occurred several time and was confirmed by a Chevrolet dealer, and was told that my warranty did not cover the issue. I took it to outside mechanic to fix the issue as Chevrolet wanted to charge over $1500 for the issue. No warning lamps, messages, overheating indicators, or other symptoms appeared before the fan remained on. The problem occurred suddenly back in 2025. Issue 2: ignition key gets stuck and cannot be removed ignition lock cylinder, ignition switch, transmission shift-interlock system, park-position switch, or steering column lock mechanism. The vehicle is available for inspection upon request. The ignition key intermittently becomes stuck and cannot be removed from the ignition. The problem occurs after parking and turning the vehicle off, and I sometimes need to move the shifter or steering wheel repeatedly before the key can be removed. A stuck ignition key can prevent me from properly shutting down and securing the vehicle. It may also indicate a failure in the ignition or shift-interlock system.

Component: drivetrain, brake, and engine management systems repeatedly fail in a coordinated pattern, with multiple warning indicators activating simultaneously and sudden unintended deceleration occurring without warning. Vehicle available for inspection. Safety risk: most recent failure occurred at highway speed with family including passengers in the vehicle. Without warning, the vehicle decelerated abruptly while multiple dashboard warnings activated at once. Sudden deceleration at highway speed creates immediate risk of rear-end collision from following traffic and loss of vehicle control. Prior dealer confirmation: yes. Curry Chevrolet (scarsdale, NY) has had the vehicle in service for the same defect category on multiple prior occasions, including stays of over a week on at least two visits. The dealer has not permanently resolved the issue — symptoms have now recurred at sixth time. An additional early service visit at the same dealer was not documented with a repair order; I retain contemporaneous text messages establishing that visit occurred. Other inspections: inspected only by curry Chevrolet to date. Gm customer assistance engaged (case #xxx). No police, insurance, or independent inspections. New case has been filed with gm, linked to the previous (case #xxx). Next service visit will be at a different authorized Chevrolet dealer for an independent diagnostic. Warning indicators: yes. In the most recent incident, multiple warning lamps and system alerts activated simultaneously at the moment of deceleration, with no advance warning. Prior incidents showed the same multi-system warning pattern, consistently without predictive indicators. Vehicle is a 2026 Chevrolet Colorado, VIN [xxx], delivered January 2026 with 2,209 miles on the odometer at delivery. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The turn signal system intermittently malfunctions. When using the turn signal, the auto-cancel function sometimes activates the opposite signal, and at times the stalk does not stay engaged when attempting to signal. This creates a safety risk because surrounding drivers may receive the wrong turning/lane-change indication or no indication at all. The issue has occurred intermittently while driving and has been presented to cox Chevrolet in bradenton, florida multiple times. Cox Chevrolet has verified turn-signal over-cancel and performed prior repairs/programming. However, the issue has not been entirely resolved and continues to occur intermittently. No crash or injury has occurred, but the condition creates a risk of collision during turns, merges, and lane changes.

My key was getting stuck in the ignition back in 2024 and the dealership replaced my shifter assembly. I am now having the same issue later after 2 years and I am out of warranty and now having to pay out of pocket. My sister has the same truck, year and color and had hers replaced. Also the service advisor said they’ve had two others come in with the same truck and had the same issue. I am unable to remove my key for quite some time once it gets stuck and I called Chevrolet themselves and they are telling me there is nothing they can do.

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.

On may 15, 2026, my 2023 Chevrolet Colorado (2. 7l l3b turbocharged engine, approximately 49,000 miles) lost its entire engine oil charge while in normal operation, and at no point did the low-oil-pressure warning light illuminate to alert me. While driving, a loud buzzing/vibrating noise developed near the upper engine and the center dash area. The vehicle continued to run with no oil-pressure warning of any kind — no low-oil-pressure light and no audible oil-pressure chime. Concerned by the noise, I immediately pulled into a parking lot and checked under the hood. The engine oil dipstick was completely dry, showing no oil whatsoever. I added 3 quarts of oil and the dipstick still showed no reading, indicating the engine had been operating with a critically low or empty oil level. Throughout this entire event, no oil-pressure warning activated. There was no external oil leak, no puddle where the vehicle is normally parked, and no oil in the coolant reservoir, which suggests the oil was being consumed or lost internally rather than dripping out — a condition the driver cannot see or anticipate without a functioning warning system. Drivers depend entirely on the oil-pressure warning system to alert them before oil starvation causes catastrophic engine damage or sudden engine seizure. An engine that seizes without warning while the vehicle is in motion creates an immediate and severe crash risk — sudden loss of motive power in traffic, on a highway, or in an intersection. The complete failure of this warning system to illuminate during a total loss of oil is, by itself, a safety defect independent of whatever is causing the oil loss, because it removes the driver's only opportunity to stop the vehicle safely before failure. These symptoms also align with existing gm service documentation: TSB 25-na-309 addresses high idle, oil consumption, oil leaks, and mil illumination caused by internal failure of the pcv oil separator, and service campaign n232415060 addresses a.

When turning off the ignition, the key will not go all the way "off" and the key will not release. If I turn the ignition back on and drive forward and backwards and slowly put the vehicle into park, and then attempt to turn off the vehicle, it will occasionally allow it at that point. It appears to be a disconnect of the system recognizing the vehicle is truly in park and when it isn't and thereby releasing the ignition off function. The engine does shut off but I think it remains in acc and will not release. Maybe safety switch in the shifter assembly.

The backup camera view does not appear on my dash screen along with all other camera views. There were no warnings or indicators. It was working the last time the vehicle was driven and then failed on the next vehicle start up.

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.

In and out of the shop for the last 3. 5 years (warranty is expired now) with multiple engin codes (cel). Most having to do with the fuel delivery systems. Most common p026d, and p1089. It has been in the shop at least 6 or more times. Gm won't stand by their product. Since the warranty ended I've put mor than $4,000 in to repairs for this and now I'm told it will cost me anouther $6000 to $7000 to repair. I bout this truck used with 60,000 miles on it and paid cash $50,000 to the dealer the originally sold it to the previous owner. I just want them to fix the issue once and for all. To date they have just thrown parts at it but it never fixes the problem. They have changed the map sensor, the fuel rail and pressure regulator, the injectors, and they've re-wired part of the wiring harness. None of this has solved the issues.

When driving normally on wet paved city roads (it had recently rained but not currently raining), my truck suddenly lost power steering and the warning messages came on to service power steering and stabilitrak systems. Traction control lights also came on. The next morning, I tried starting the truck again, and the power steering came back temporarily before losing it again and service messages came back on. I've read many others in online forums have had this same electrical connection issue, and it was a recall on the 2015 model year of this same truck.

The headlights flicker/pulse creating visibility issues at night. This occurs when the heated seats are activated. This is a safety concern for myself, passengers, other drivers, and pedestrians. Flickering lights can cause an accident due to poor visibility and the creating of false shadows. This would also hinder the ability to see pedestrians. The problem was reproduced at the local Chevrolet dealer, they said they would contact Chevrolet, at my insisting. Initially they told me I should replace the stock halogen light bulbs with aftermarket led bulbs at my cost. They said it is extremely unlikely that gm will do anything to rectify the issue because from the design standpoint of the vehicle everything is operating within its standards on paper. The manufacturer has initiated a case. There are no warning lights of any kind. This is a 2025 with 2,300 miles.

The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving at various speeds, the vehicle experienced a sudden loss of automotive power. The power steering message was displayed on the instrument panel. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 199,106.

The electric power steering system on my vehicle intermittently fails while I am driving. When the failure occurs, the steering suddenly becomes extremely heavy and difficult to control, creating an immediate safety risk to me and to others on the road. The loss of power steering has happened multiple times with no advance warning. Each time, the only way to temporarily restore normal steering is to pull over, turn the vehicle off, and restart it. The problem occurs randomly and without a pattern. The vehicle is available for inspection upon request. The issue has been evaluated by the dealer’s service center. They were not able to reproduce the failure during their inspection, but they did confirm that the vehicle had stored a diagnostic trouble code indicating a power steering failure. The service center reported that the code was too generic to determine the root cause, and no repair was performed. They acknowledged that the steering failure had occurred based on the stored code, but could not identify why it was happening. During the failures, the vehicle displays warning messages stating that both stabilitrak and power steering have failed. These messages appear only at the moment of failure, with no prior warning lights or symptoms. This intermittent loss of power steering severely compromises safe operation of the vehicle, especially when turning at low speeds, entering or exiting parking lots, or navigating intersections. It puts me, my passengers, and the surrounding drivers and pedestrians at risk because the vehicle cannot be steered normally when the failure occurs.

2024 Chevrolet Colorado with intermittent safety defect at highway speeds. Vehicle displays p215b along with service esc, service traction control, and reduced acceleration. Speedometer becomes erratic and the vehicle loses reliable speed signal at highway speed. Dealer kept vehicle for 15 days, stated repairs were made, but the same issue returned within about 2 miles of pickup on the highway. Vehicle was returned to dealer immediately. As of April 2, total days out of service will be 21. I do not believe the vehicle is safe to drive or safe to transport my family in. Gm case has been opened. This is an ongoing safety issue involving loss of speed signal and reduced acceleration during highway operation.

The engine coolant temperature gauge is stuck at approximately 160•f. Cooling fans are running at high speed constantly. The thermostat is stuck in the open position. The vehicle is less than 100,000 miles. There is a “special coverage bulletin n242484760” that has indicated the issue is occurring regularly with my type of vehicle but my specific VIN is excluded due to misplaced parameters. The part is readily available at the dealership in which we are getting the part fixed because so many vehicles of my make and model are having this issue. The cost of the repair will be $1,200 and will be out of pocket because my VIN is excluded but clearly affected by the same faulty system for the coolant. This is a mistake as my vehicle is have the exact same issue as all of the others “covered” in the special coverage. We are seeking an appeal and want to file a complaint that my vehicle is excluded and will have to pay $1,200 where other customers will not be required to do so.

Ecm engine control module tcm transmission range sensor tcm transmission control module while driving in a 45 mph speed zone in heavy traffic, the vehicle suddenly lost power and abruptly slowed down causing a number of other vehicles to have to break and swerve . Problem confirmed through onstar diagnosis as of this date, the gm dealer has not confirmed the problem. No other inspections have been confirmed. There were no warnings prior to the event.

Had safety recall for loss of power steering repair done in November of 2021. First incident: leaving a grocery store parking lot, loss of power steering made the steering nearly impossible at low speeds. Message on display said to have steering serviced and dinged. Had a tow truck come and take it to the same dealership that did the repair. Low voltage code was reset, power steering was returned. Dealership wanted $2. 3k to repair. Second incident: one month later, pulling out of my driveway when the same message displayed and the dash dinged. Had a tow truck take it to a different repair shop, same issue, same resolution. $2. 4k repair. I declined both repairs.

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.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving on several occasions at various speeds, and the brake pedal was depressed the pedal remained floored. The contact stated that the vehicle eventually slowed down on its own and came to a complete stop. The was towed to a dealer where it was diagnosed that the master cylinder needed to be replaced. The vehicle was repaired but the failure reoccurred a little over a month later. The vehicle was towed back to the same dealer where it was diagnosed that the battery was dead and the battery needed to be replaced. The vehicle was repaired but the failure reoccurred approximately 17 days later. The vehicle was taken to the same dealer where it was diagnosed that the drivers door wire harness needed to be replaced due to an electrical issue that killed the battery. The vehicle was repaired but the failure reoccurred approximately four months later. The vehicle was towed to the same dealer where the vehicle has yet to be diagnosed as of yet. The manufacturer notified of the failure. The failure mileage was approximately 8,400.

Vehicle: 2023 Chevrolet Colorado trail boss mileage: approximately 14,000 miles I am submitting this complaint because the abs braking system on my vehicle activates unexpectedly and causes a temporary loss of braking when driving over uneven pavement. When braking over potholes, bumps, or rough road surfaces at low to moderate speeds, the abs system engages even though traction is available. When this happens, brake pressure is reduced to the point where the vehicle does not slow as expected. The abs warning indicator flashes briefly, and there is a noticeable delay before normal braking resumes. This behavior has occurred multiple times in normal driving conditions on city streets, not during panic stops or slippery conditions. The issue feels most pronounced when approaching intersections or slowing in traffic over broken pavement, where consistent braking is critical. The momentary reduction in braking force significantly increases stopping distance and creates a safety concern. The vehicle has low mileage, has not been modified, and is maintained as delivered from the manufacturer. There are no warning lights remaining on after the event, and the issue appears to be related to abs calibration rather than driver input or road conditions. This does not feel like normal abs operation and gives the impression that braking is interrupted at the exact moment it is needed. Given the frequency and repeatability of the issue, I believe this represents a potential safety defect that could contribute to a collision, particularly in urban driving environments with uneven road surfaces. I am submitting this complaint to document the issue and to request that the abs braking behavior on this vehicle be reviewed for safety.

Any time the heated seats and or steering wheel heat are on the lights pulsate inside and outside the vehicle. I have complained to the dealership and chevy. Neither one has any answers for this. Chevy admitted via email finally that it was an issue but they did not have a fix at this time and the vehicle was safe. I find this to be a safety issue due to the lights pulsating and that apparently it is pulling too much power somewhere. To me this could cause a fire. For the money I paid for a brand new vehicle you'd think they would be willing to figure this out quickly. I know of others who have this issue as well with the same response from chevy. They apparently do not care about the safety of the people who purchase their vehicles.

While driving my 2024 Chevrolet Colorado, both the infotainment system and the instrument cluster reboot unexpectedly. During these reboots, the speedometer, fuel gauge, and warning lights are unavailable for at least 30 seconds. This has occurred multiple times at highway speeds, creating a serious safety concern because I cannot see my speed or critical vehicle information while the system resets. Restarting the vehicle sometimes restores functionality, but the issue recurs intermittently. I have checked with my dealer, and no permanent fix or recall has been issued by gm at this time. This defect poses a risk to driver and passenger safety and should be investigated promptly.

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.

When the truck is driven there are times at random that the steering wheel locks into place while driving at any speed on the road. This warrants me to slowly try and get the car off the road to shut it down and restart it and then the steering goes back to normal. This has happened multiple different times on different days. This has not happened on the highway yet, but if this occurs while driving on the highway this poses a huge risk for an accident to occur. Chevy has had this similar recall on previous 2015s and it seems that 2016 owners are complaining about this issue but it is yet to be a recall.

All the sensors seem to not be functioning correctly. Doesn't tell me the right measurements for the wheels, gas, over heating. Right front passenger door locks/unlocks when it wants. It chokes up when trying to accelerate. Theres a rattling noise that comes from under the car. First time I took it to the dealership, they stated it was a bolt that had come loose on the exhaust pipe. They placed a new one which lasted a year and a half and now its back to making the noise. I took it again to the dealership, this time they claimed they couldn't find anything. My airbag sensor keeps coming on constantly. My fuel sensor claims 116 miles one moments and 5 or 6 minutes later, it says I have 50 miles. My car was over heating and low on anti-freeze, the car never notified it was over heating.

[instrument cluster black-out] while driving on I-15s, suddenly the instrument cluster went completely dark for 5-10 seconds. A scary and alarming development.

Stabilitrak error intermittently while driving accompanied by loss of power steering and electrical.

Stabilitrek error popped up and traction control lights came on and there was a sudden (brief) loss of electrical power when I turned on high beams.

I’m having an issue with my power steering assist. It just goes out while I’m driving. I almost hit a telephone pole one day almost 2 cars two other times. It started about seven months ago when you pull over shut off the truck open the door to break continuity for the electrical system close the door and start it. It goes back to working normal. It’s gotta be part of the connections underneath the power steering assembly unit itself, but there is no recall for my specific VIN.

October 2025----problem with 2017 Chevrolet Colorado wt with 2. 5l engine and 6 speed automatic. It has 57,000 miles on it. Original owner--bought new. "stabilitrak" warning light came on when I first started the pickup in the morning and stayed on. Then a message appeared saying that there could be a steering issue or a control issue operating the pickup and to take it to the dealer for service. Colorado starts normally and runs normally. Only issue is the warning light for the stabilitrak is on constantly. I read in the manual that tcs(traction control system) and the stabilitrak system have been disabled. The owner's manual states "the vehicle is safe to drive; however, you do not have the benefit of stabilitrak, so reduce your speed and drive accordingly. " have a dealer service the system. I have had no safety issues or risky situations. Have about 300 miles added since it occurred. It has not been inspected yet by a dealer.

Stabilitrak error and traction control lights came on and electrical power flickered off and on when I rolled up passenger window.
