   On May 15, 2026, my 2023 Chevrolet Colorado (2.7L L3B turbocharged engine, approximately 49,000 miles) lost its entire engine oil charge while in normal operation, and at NO point did the low-oil-pressure warning light illuminate to alert me. While driving, a loud buzzing/vibrating noise developed near the upper engine and the center dash area. The vehicle continued to run with no oil-pressure warning of any kind — no low-oil-pressure light and no audible oil-pressure chime.…

   My 2023 Chevrolet Colorado (2.7L, approx. 49,000 miles) experiences sudden, intermittent loss of motive power involving the 8-speed automatic transmission. The transmission sets codes and the vehicle drops into limp mode, capped at roughly 45 mph, without warning. The most dangerous symptom is a total loss of acceleration from a stop, especially on inclines — pressing the accelerator produces no response. On one occasion, stopped on a slight incline, the vehicle rolled…

   Engine light came on. Fan ran high. Had it towed to the dealership. Has 39,000 miles on it. Needs a new upper radiator hose due to a defective hose. Apparently, after reading online, GM is aware of this issue. Now we have to pay the diagnostic fee and $850 for a new hose and a flush, as well as the tow bill! Now can’t get the part for a week or 8 days and then have to wait on the repair. This is unsatisfactory that there is a known problem and isn’t covered or hasn’t been a…

   Faulty Radiator Inlet Hose, upper radiator hose failure, outlined in PIT6494A. This is the third time that the light on the dashboard has come on for failure, the first time they "Fixed it" the second time they said it was the Battery, it was NOT!!

   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.…

To my knowledge, which is limited on vehicle diagnosis, the engine valve body is having an issue finding a gear when starting from a stop. How was your safety or the safety of others put at risk?
