2024 Chevrolet Colorado Engine Problems

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 35k 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.

I have had my vehicle for less than 2 years and less than 25,000. I had it in for regular maintenance and was told I had no coolant. After a pressure test the dealership told me I had a large crack in the coolant line. It will 2 weeks to get the part and I can’t drive my truck. This needs to be made a recall and the part needs to be made available asap.This could of caused serious damage to my engine and could of cause me to have an accident.

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.

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.

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.

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!

Incident

Oct 27, 2025

A leak in the upper radiator coolant intake hose has been found. This leak is the result of a bad rubber o-ring in the connection between the radiator and the hose. This has resulted in coolant regularly leaking from the vehicle causing power train issues, health and safety concerns where toxic coolant is leaking and environmental concerns. A loud “whooshing” noise was heard from the engine bay prior to eventually a check engine light being illuminated when the coolant level became low enough.

Immediately after braking in traffic or at a complete stop the there is hesitation with the accelerator. If I have to brake in traffic on the highway and then need to accelerate to enter another lane the vehicle will not accelerate for several seconds making it dangerous if the traffic in the other lane is traveling at a higher speed. At a stop sign when looking both ways to make sure the road is clear if I need to accelerate quickly the car will not move for several seconds no matter how far I push the accelerator. This almost led to a crash at a limited visibility intersection. I have not taken it to the dealer yet, but that is the next step.

Brand new TRUCK… 2024 Chevy Colorado LT 4x4.. Classic Chevrolet Oklahoma CIty OK Extremely Rough Idol, on cold engine start up, You can hear the ROUGH noise it coming out of the Exhaust and feel it in the cab of the truck. After warm up,, at intersections on red lights ,,you can hear and feel the idol miss at times a little bit. The dealership has had my truck for 8 days now. NO positive results to date. They say GM is making them go through a step by step process. The service manager tells me there is a code in one of the cylinders.. but the injectors test perfect. Looking on GOOGLE i see many owners of the same truck with the SAME issue !!!

The vehicle was purchased new from Courtesy Chevrolet in San Diego, CA. After 500 miles on the odometer, I decided to change the oil with fresh Castrol Syntec 5W-30 which has the Dexos 1 Gen3 approval along with a new ACDelco PF66 oil filter. Upon removing the oil drain plug and after all of the oil had been drained, I noticed the threads for the oil drain plug appear to be loose and perhaps broken free from the stamped aluminum oil pan. Luckily, I was fortunate to obtain a perfect seal while pulling on the drain plug and threading it into the pan. The attached images are from a new oil pan I purchased. The steel threaded insert inside the stamped aluminum oil pan has broken free and the only way to properly repair it is to have the factory oil pan replaced with another. The design is poor and there is no way to prevent the threaded insert from falling into the pan rendering the vehicle inoperable. I will be taking the vehicle into the dealership to express my concern.

I was driving the vehicle up a mountain, in a 70m speed zone, when the dash board lit up. The vehicle started to decelerate, I pushed the gas petal but it just decelerated. I put on the emergency light and continued to the exit. Stopping in Liberty Pa, at an Exxon station. Called GM roadside assistance. On-Demand Diagnostics stated: ECM-Engine System code P00700. TCM P0658, TCM P2729, and P281D. Odometer reading 3840. Remaining oil life: 49%. Our safety was compromised by the unexpected deceleration of the vehicle and possibly being stranded on the road. Was luck to get off the highway safely. The car was towed to Jack McNerney Chevrolet, Inc. 363 NYS Rt13, Tully, NY 13159 +13156968976. The car has been at the dealer since the night of [XXX]. Have been told that the car is not drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Date: [XXX] | Location [XXX] Leaving Costco 1 ½ after entering entrance headed to Savannah. I was traveling at approximately 60 miles a hour with heavy traffic alongside me and a tractor trailer behind me when I felt my Truck quickly de-accelerate on its on. Then I saw the “Sudden Warning on Dashboard, “Reduced Acceleration – Drive with Care” then the 2nd Warning on Dashboard, “ Service Traction Control.” I was almost REAR ENDED by the Tractor Trailer. I was never so startled but I keep my nerve….got over to the right lane at slowed speed (It was weird. Speed slowed but felt like I was in high gear….) I droves about a ½ mile …. got off at next exit and pulled over at gas station. I turned car completely off and tried to reset computers, but it would not. I decided to drive under 35 miles a hour on side streets to Dan Vaden dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
