My 2023 Chevrolet Colorado ZR2 cannot receive overâtheâair (OTA) software updates because the gateway module is still running outdated firmware (XXX.mnf). General Motors issued Service Update XXX to correct this defect by performing a vehicleâwide programming update. However, GMâs system incorrectly shows the bulletin as âclosedâ for my VIN even though the gateway module was never updated. The truck was sold to me by Tyrell Chevrolet in [XXX] with this safetyârelated service update not completed properly. The dealership has confirmed they cannot perform the required update because GMâs system will not authorize it until the bulletin is reopened. GM corporate has been contacted multiple times, but after several days they have not reopened the bulletin or provided a resolution. Because the gateway module remains on outdated firmware, the vehicle cannot receive critical OTA updates related to safety, diagnostics, and module stability. This condition has been reported by other 2023 Colorado owners and has previously been associated with batteryâdrain issues caused by software modules failing to sleep properly. GM has acknowledged the defect by issuing Service Update XXX, but they are refusing to reopen the update for my VIN despite the incomplete firmware and the vehicleâs inability to receive OTA updates. I am filing this complaint so the defect and GMâs refusal to correct it are formally documented. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My truck has used automatic emergency braking multiple times while driving at variable speeds with no obstacles or vehicles in front of me causing whiplash and further damage to my neck that has 5 budging discs.   Since Iâm only allowed to add a specific mileage and speed below, Iâll note here that itâs happened since I purchased the truck with roughly 35000 miles on it to the current mileage of 44000 and between speeds of 30mph-75mph.

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 canâ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 isnât covered or hasnât been a recall.

CHEVROLET COLORADO 2023 ENGINE

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 â no low-oil-pressure light and no audible oil-pressure chime. Concerned by the noise, I immediately pulled into a parking lot and checked under the hood. The engine oil dipstick was completely dry, showing no oil whatsoever. I added 3 quarts of oil and the dipstick still showed no reading, indicating the engine had been operating with a critically low or empty oil level. Throughout this entire event, no oil-pressure warning activated. There was no external oil leak, no puddle where the vehicle is normally parked, and no oil in the coolant reservoir, which suggests the oil was being consumed or lost internally rather than dripping out â a condition the driver cannot see or anticipate without a functioning warning system. Drivers depend entirely on the oil-pressure warning system to alert them before oil starvation causes catastrophic engine damage or sudden engine seizure. An engine that seizes without warning while the vehicle is in motion creates an immediate and severe crash risk â sudden loss of motive power in traffic, on a highway, or in an intersection. The complete failure of this warning system to illuminate during a total loss of oil is, by itself, a safety defect independent of whatever is causing the oil loss, because it removes the driver's only opportunity to stop the vehicle safely before failure. These symptoms also align with existing GM service documentation: TSB 25-NA-309 addresses high idle, oil consumption, oil leaks, and MIL illumination caused by internal failure of the PCV oil separator, and service campaign N232415060 addresses a
