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.

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.

While driving a warning will pop up and says "stabilitrack. " all I can do is put my hazards, wait on the side of the road, and turn off the vehicle to see if it goes away. I can't drive in that state as the steering wheel gets really hard to control. The steering that make it easier to move the steering wheel (left and right to drive) goes off. So, I am having to put all my strength to make a turn or continue driving. It becomes a huge problem when I am on the highway as it can cause an accident.

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.

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.

Intermittent loss of power. Power returns when wiggling the battery.

While driving, my 2016 Chevrolet Colorado experiences sudden voltage drops and intermittent loss of power steering assist — the same symptoms described in the 2015 Chevrolet Colorado recall (NHTSA #16v054000). When the failure occurs, the steering becomes extremely heavy and unsafe, especially during low-speed turns or lane changes. In September 2024, I brought my truck to an authorized Chevrolet dealership for sudden loss of power steering and electrical issues. A diagnostic was performed, and a fuse was replaced — they claimed that fixed the issue. Not even a month later, in October 2024, I brought my truck back to the dealership for the exact same issues. They confirmed a voltage drop but could not identify a specific cause. They verbally advised me they “cleaned the connectors,” which temporarily fixed the problem. Approximately one year later, in October 2025, the same issue returned — identical symptoms and voltage behavior. My truck was manufactured in August 2015, which is close to the recalled 2015 production window. Based on the symptoms and timing, I believe my truck may have been built using the same steering components or wiring harnesses as the recalled vehicles. This appears to be the same safety defect that caused the 2015 recall, only affecting a slightly newer VIN range. I request that NHTSA investigate whether additional 2016 Chevrolet Colorado vehicles built in mid-to-late 2015 should be included in the recall for loss of steering assist. No service lights will be on and suddenly while driving I will get “service stabilitrak”, “no traction control”, and “service power steering”. Turning off my vehicle and restarting will temporarily fix the issue. Chevrolet Colorado, 2016, steering assist loss, voltage drop, power steering failure, recall 16v054000, safety defect, connector corrosion, torque sensor wiring harness, electrical failure, early production 2016.

The infotainment system is not functioning. The screen will come on as I turn on the truck, then it goes blank. Sometimes it flashes and then goes black. I cannot use any of my apps or connect to apple carplay. This has been going on for months now. I have complained to Chevrolet and the dealership. They have failed to provide a solution. This truck only has 35,000 miles on it. We can no longer take it on trips because we have no navigation, especially in areas where WI-fi may be hard to connect to by just our phones. We have followed all the trouble shooting provided in the chevy app or online and nothing helps.

I have had 3 separate occasions where the automatic emergency braking has engaged with nothing in front to trigger it. Each time was one a busy section of road, two of those times I had traffic behind me nearly causing an accident.

When using heated seats and heated steering wheel the headlights randomly pulsate and dim - dangerously impacting driver night-time vision / visibility and confusing / disorienting other drivers. Ongoing issue. Happens every time headlights are utilized in conjunction with heated seats and heated steering wheel. Occurs at idle and at speed. Chevrolet refuses to acknowledge, address, or remedy the issue. Has not been remedied to date. Videos available.

Starting on 08/13/2025 while driving the truck, the gauge cluster and radio went completely out (black screen) and the five red automatic emergency braking led's illuminated and stayed on for up to 5 minutes. This happened about 8 times on my commute home. This happed again on 08/14/25 after the dealership did a software update to resolve the issue. The truck was serviced again on 09/11/2025 and I was told that gm has no software fix for this at this time. On 09/25/2025 again the truck was serviced again to try and fix the issue. This time the radio came on and I could not turn it off or adjust the volume. I went straight to the dealer and showed the issue to the service manager james mask. The cluster and radio to this day continue to go out (black screen), no speedometer, gauges of any sort for a period of time from 15 seconds to 30 minutes. This leaves me with no way of obeying the speed limit, fuel level, oil or temperature gauges. Gm is being blasé about this. They have admitted they know the issue exists but can't or won't offer a fix for the issue.

Power steering failure identical to recall #16v054000 (issued February 2016) on 2015 Colorado. Vehicle will unexpectedly lose power steering udden stiff steering and both “service power steering” and “service stabilitrak” warnings appear on dashboard. Defective parts appear to be gear assembly (gm part #23228020) and revised torque sensor cover kit (gm part #84344239).

Power steering and stabilitrak warnings were displayed while I was driving and I immediately lost power steering while trying to execute a turn off the highway. This almost resulted in an accident. Warnings have been displayed twice now without prior incidents, and no warning that I will lose power steering. I have not taken my vehicle in yet, but other owners of 2016’s have reported the same issues with no response from the manufacturer. The 2015 model had a recall for the exact same issue with the exact same part number, however they will not address the issue in the 2016 model. This is a public safety issue as accidents and even death can occur if one loses steering while driving.

Fpcm code p069e. Engine stalls when slowing down. Local dealer says to check wires around water pump area if rubbing and unsecured.

My 2016 Colorado is having a power steering failure identical to the 2015 recall. Recall #16v054000 (issued February 2016) covered 2015 Colorados and canyons with the same type of electric power steering (eps) gear assembly prone to internal corrosion. Exact failure symptoms: sudden stiff steering, steering wheel locks/stiffens “service power steering” or “stabilitrak” warnings dtc codes like u0073, u0101, c0545, etc. Defective part: original gear assembly: gm part #23228020 revised torque sensor cover kit (to prevent corrosion): gm part #84344239 the vehicle has been taken to the dealership in January when this failure first occured. The dealer claimed it was due to the corroded negative battery cable. I explained that this was a known issue and a recall had been issued for the same part on the 2015 model. They refused to investigate further. On 07/14/2025 the issue resumed and repeated after restarting the vehicle till it reset no more and remained without power steering. I dropped off the vehicle and one rep informed me that this issue was due to wear and tear and that my vehicle was not on the list of recalls. I spoke to a supervisor and he said they would look into it but it did not sound promising.

My 2018 Chevrolet Colorado diesel has had repeated diesel emissions/dpf-related failures that cause the vehicle to enter reduced-power or limp mode. This is a safety issue because the truck suddenly loses power and cannot accelerate normally. The most serious incident occurred while driving over santiam pass in oregon. The vehicle went into reduced-power/limp mode on a mountain highway, leaving me unable to maintain normal speed or accelerate safely. I lost power needed to pass traffic and had limited ability to respond to road conditions. The problem has happened several times. It has also occurred while I was towing my boat, which left me unable to continue the trip safely and created a hazardous situation because the truck could not maintain normal towing power. The issue appears related to the diesel particulate filter/emissions system and repeated dpf/regen or exhaust aftertreatment problems. I am concerned that a design, calibration, or emissions-system defect is causing sudden power reduction during normal driving and towing. This creates an unreasonable safety risk, especially on mountain passes, two-lane highways, and while towing. I am requesting that NHTSA review this as a potential safety defect involving the 2018 Chevrolet Colorado diesel dpf/emissions system and reduced-engine-power strategy. I am also requesting that this complaint be considered with any similar complaints, recalls, technical service bulletins, or emissions campaigns related to dpf regeneration, particulate matter sensor diagnostics, reduced engine power, or limp mode on the 2. 8l duramax Chevrolet Colorado.

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.
