2024 Chevrolet Colorado: engine overheating

Filed Aug 31, 2026 · Engine · CO

Engine cooling system has a known leak. It is rather expensive out of pocket and although there is now a tsb the tsb does not cover the danger of overheating an engine and being stranded on the side of the road. Also the coolant leaking causes an unseen hazard by polluting water supplies with one of the more known toxins to the water and environment.

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.

Coolant leaking from the upper radiator inlet hose connection

Filed Mar 11, 2026 · Transmission · MN

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.

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.

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

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!
