2024 CHEVROLET COLORADO Complaints

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 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.

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.
