Mid December 2025 my forward collision warning, adaptive cruise control, automatic emergency braking and auto high beams all stopped working. I combined the repair request with my next oil change Dec 22, 2025. The Chevy dealer, Serra, advised me that Chevrolet had no way to correct these problems, one of which was a $950 option. I have returned to the dealer more times, still no fix. I have talked to Chevrolet customer service, asked for a buy back, or car to drive till repairs and was denied. Chevrolet simply says just wait till we figure out how to fix our broken truck. I feel Serra Chevrolet has done all they can and has otherwise provided me with excellent service. Since the problems include safety features and I have waited over 4 months to date, I hope your agency can expedite the repair and secure some type of compensation for me.

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.

I have a 2024 Chevy Colorado Trail Boss that needs an Upper Radiator Coolant Hose. But apparently this is on nationwide backorder because although there is not a recall GM put a bulletin out they are aware of the issue that appears to be a degraded seal inside hose fitting so the whole hose needs replacing. I live in [XXX] and it is not available here and I have called OH, [XXX] , [XXX] and other state dealerships and Noone will sell that part because of the backorder. My truck has 40k miles. And every dealer I called this is a huge issue with these trucks. So it is not a wear issue when it is on nationwide backorder and it'll take 1-2 weeks +/- to get. My warranty won't cover as they say it is a wear part and no recall. So how can there be no recall on a nationwide issue with these trucks. My truck cant be driven right now due to check engine light, low coolant, leaking hose, fan blowing high, no heat and this is all related to this backordered part. Someone told me to report this issue so that is what I am doing now. Again this should be an active recall.

When coming to a stop the vehicle slams into 1st gear raising the RPMs and pushing the vehicle forward even when the brakes are being applied. No warning lights no other malfunction or symptoms. Has occurred this I first purchased the vehicle new in January of 2025. Has almost caused collisions. Never took it to the dealership due to the information I've gathered if was a common issue but I believe it is a major safety concern due to the vehicle lunging forward when the brakes are applied.
My truck only has 16,600 miles on it and the rotors and brakes are already shuddering. The dealership told me I needed my front and rear brakes and rotors replaced. It is beyond ridiculous when my last truck a 2020 Chevy Colorado had no rotor or brake problems and have 90,000 miles when I traded it in.
At ~20,300 miles, severe chassis and steering wheel vibration occurred during high-speed highway descents while braking. Safety risk: reduced steering control at highway speed. The vehicle was inspected by a franchised Chevrolet dealer in Lakewood, CO. The technician's written service notes document rear rotor Lateral Runout (LRO) of 0.006 inches against GM's maximum allowable specification of 0.002 inches per GM Service Bulletin 00-05-22-002 — 3x the engineering limit. The defect was confirmed in dealer documentation and is available for inspection. After I identified this discrepancy, the Service Manager claimed the technician meant 0.006 mm (metric). Photographic evidence from the dealer's own diagnostic video shows a dial indicator clearly labeled in 0.001-inch increments with the needle resting on the 6th tick mark. A metric reading of 0.0002 inches is physically impossible to display as 6 full divisions on this tool. GM Customer Assistance denied the warranty claim, classifying it as maintenance. Lateral Runout is a geometric specification, not a wear measurement. A rotor 3x out of tolerance at 20,300 miles is a material or assembly defect. No warning lamps appeared. The safety concern remains unresolved.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving at an undisclosed speed, the brake pedal depressed to the floorboard and was spongy. Additionally, the navigation system shut off unexpectedly, and the Forward Collision Avoidance warning light illuminated, causing the seat belt to tighten while the vehicle was in park. The contact also received OnStar alerts that the vehicle was being stolen and that the 12-Volt battery voltage had dropped. The manufacturer was not notified of the failure. The vehicle was driven to the dealer to repair the issues, but the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 8,285.

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.
A few weeks ago the heat started performing intermittently, about half the time only blowing out cold air even with the temperature set to 85°. I live in Minnesota and we have had numerous weeks of below 0 temperatures. Lo and behold, I find out there are widespread reports of the O ring seals on the radiator and heater hoses failing and causing coolant leaks. These leaks are significant enough to render the vehicle inoperable and with no cabin heating or cooling. This could lead to life-threatening situations in adverse weather conditions. It could also create dangerous roadside failure situation in heavy traffic, particularly on interstate highways. Dealers are aware of the issue and are currently repairing vehicles under warranty. However some dealers are telling owners that the cooling system is not part of the engine and drivetrain, and therefore is not covered under the original factory warranty if the vehicle has exceeded the initial bumper to bumper warranty limits. Dealers are also telling owners that parts are on backorder due to high demand, and that repair wait times could take weeks. The vehicle is unsafe to operate with a known coolant leak.
there have about 4 incidents where my vehicle has engaged the automatic emergency breaks while I’m driving, even though there are no cars around me close enough to cause that reaction. called 911 on most recent incident to get medical evaluation to check chest from seat belt sudden locking

Upper radiator hose leak with 36,750 miles(just out of warranty) 3 days after it was at dealer for oil change and replacing the heat shield. Apparently VERY common in these vehicles which says they are aware but haven't FIXED the issue, should be a RECALL!!

Copied this from a forum and it's the same thing for me. I'm editing to fit my unique situation. This is an $800 repair at my dealer for a $40 part! 5 day backorder so I'm without a vehicle.

The contact owns a 2024 Chevrolet Colorado. The contact stated that the roof of the vehicle had several dents. The contact became aware that several similar vehicles had the same dents to the roof. The contact referenced NHTSA ID Number: 11014388 (STRUCTURE) as the cause for the failure; however, the VIN was not included. The dealer was notified of the issue. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 72,000.
Check engine light appeared and fans kicked on loudly. Stayed on even after shutting the vehicle off. Vehicle is a 2024 with only 28,639 miles on it. Upper radiator hose was leaking and would not seal. Took to dealership for repair and replacement. Was informed it was the 3rd Chevy Colorado this week with this issue! Was stunned. Further internet research found a staggering number of forum posts with this same issue. This is a recall-worthy issue at this point. Please consider issuing a recall based on the safety issues this may pose if engines seize or overheat as well as the sheer number of the same reported incidents.
upper radiator fitting is leaking, Chevy is replacing the radiator and the hose
The truck has 28,000 miles and has been only driven for commuting on interstate conditions. While traveling on an 80 mile commute, I experienced complete engine failure while traveling at 75 MPH (the posted speed limit is 80). As the engine failed, I was placed in a dangerous position as there is no pull-off and traffic was heavy. I was stranded in winter conditions with no ability to heat or stay warm. OnStar assisted with a tow to the closest dealership which was Ressler Chevy in Bozeman, MT. The results of the inspection indicated a failed crank shaft, hole from internal debris in the engine block, and the engine seized. This has resulted in a engine replacement. When asked, this has been an ongoing problem with the 2.7 engine yet there is no recall and the fix is to replace it with another 2.7 with no fix to the issues. This truck has received all required maintenance through Chevy dealerships and has no upgrades or changes from the manufacturer settings when purchased a year ago. There were no signs, symptoms, or warmings prior to the engine failure.
Radiator hose failed in under 1.5 Years on 2024 Chevy Colorado. Parts are back ordered for months, this is clearly a manufacture defect that could lead to overheating the engine and engine damage and failure
Not sure if this is your typical safety issue. Voice activation button @ RH side of steering wheel failed approx. one month after vehicle purchase. This button allows one to call out, use GPS, vehicle functions, radio, etc "handsfree". Message @ infotainment screen stated "click here to purchase subscription" which I was not made aware of by anyone involved w/ sale. Cell phone will link up w/ vehicle manually for sending or receiving calls, but requires holding phone to start or end them (and pick who you want to call)...which is illegal in California and unsafe. Inquiring w/ Onstar led to having to pay for monthly subcription to "reenable" functionality. Seeing as this IS a safety item, I wonder why I would be required to pay a monthly 45.00 fee for it to function. Had a 2015 Ford that worked perfectly...for free

Even when new, the truck would abruptly down shift from 2nd to 1st, every now and then. Then with about 3000 miles on the truck its started doing every time, once the transmission is warmed up. It seemed to get better and then started again with about 4000 miles and kept getting worse. It got so bad that the truck would shudder and it almost felt like I was getting rear ended and you could hear knocking from the transmission. I then turned it in the dealer and when I got it back, the dealer stated that they had to replace a valve in the valve body.
problem since day 1. Instrument cluster goes dark frequently. no speedometer or gauges are illuminated. may stay dark for long periods of time and other times it is shorter periods. sometimes smacking it will bring it back up. sometimes not. cluster changed 2 times by dealer. problem continues. code read problem with harness connector showed up once but they cleared it and it hasn't come back. panel went dark 12 times the other day in 30 miles. dealer is now ignoring it! 80 year old man driving at night with no instrumentation is a serious hazard and POTENTIAL lawsuit!!

Right turn signal auto cancel activates the left lane change signal resulting in oncoming traffic assuming a left turn to be performed but this vehicle continues straight resulting in a collision hazard. This has been happening since the purchase of the vehicle 2.5 years ago but dealer is unwilling to fix.
The front brake pads are showing extremely uneven ware. Outer brake pad is at 2mm and the inner is at 7mm due to a spring issue on the front caliper. There is also a lip on the left rotor. The tech used 25-NA-365 to help identify the issue. However, my VIN is not covered under this repair. The result is a $500 out of pocket repair for something that should be a mfg defect and not wear and tear. As this was already outlined as an issue with other 2024 Chevy Colorado's I am asking this to be expanded to cover my vehicle as well. The issues was also causing my brake sensors to "detect" new brakes and I had to inform the vehicle that I have not had brake service done to trigger this alert.
Starting on [XXX] 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 [XXX] 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Visibly observed antifreeze / coolant leaking from top radiator hose where it connects to the radiator. Dealer replaced upper radiator o-ring but it's still leaking. At 17000 miles a service brake warning message showed up on information screen. Front brake rotors are warped. Dealer states normal wear on front brakes. Also the dealership stated the front left inner brake pad was down to 2mm of pad left. Wanted over $420 to turn rotors and replace pads. I inquired why the left front pads were worn so much than the right side. They stated this was normal!

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.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while attempting to add windshield washer fluid to the windshield washer fluid reservoir. The contact stated that the washer fluid failed to pass through the filler neck and enter the reservoir. The vehicle was taken to the dealer, who informed the contact that the failure was due to a poor design flaw and that there was no repair available currently. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 14,000.
After completing a right turn with a right turn signal, the vehicle will signal a left turn for 3 blinks.
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.
