2024 Chevrolet Colorado Complaints

Check engine light came on and the dealership said it was because the coolant was low due to the radiator hose leaking. I was told by the actual mechanic that they’ve had to do a lot of radiator hoses and that it is a known defect with the Colorados and the traverses but that GM hasn’t done a recall on them yet. That is what brings me here. My truck is only 2 years old and this shouldn’t be happening right now. Thank you for taking the time to review this and I hope GM addresses the matter promptly.

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.

Truck has 36,669 miles check engine light came on and was idling loud, after being looked at my a Chevrolet dealership came back a faulty radiator hose, and coolant was leaking. Too new of truck for this kind of problem

Coolant leaking from the upper radiator inlet hose connection. The Malfunction Indicator Lamp (MIL) illuminated in the Driver Information Center (DIC).

The vehicle is registered to me; my mother was the driver at the time of the failure. At ~2,963 miles, the truck developed intermittent check engine and ABS warning lights. The dealer pulled DTC C058A (brake system control module) and P25A2. Per GM bulletin PIT6012A, the battery was replaced and a brake plunger motor sensor learn was performed. The same codes returned within weeks. The dealer then diagnosed internal failure of the brake master cylinder and reservoir, documented the vehicle as "unsafe to drive," and replaced both under warranty. The truck sat at the dealer over six weeks due to a nationwide parts backorder. Repairs were completed April 4, 2025. On May 2, 2025, at ~6,500 miles, the driver was traveling downhill on a city street in the rain at roughly 20 mph. The brake pedal suddenly became hard and resistant. Despite full-force pedal pressure, the vehicle could not be stopped. It entered an intersection, struck another vehicle, then struck a tree. Front and side airbags...
