2023 Chevrolet Colorado

The contact owns a 2023 Chevrolet Colorado. The contact stated that while the vehicle was parked, there was smoke coming from the front tires, and the tires were extremely hot. No warning lights were illuminated. The contact became aware of the burning tire odor coming from the vehicle. The vehicle was taken to an independent mechanic after a tire rotation. The contact was informed that the calipers and brakes had failed and needed to be replaced. The vehicle was scheduled for the necessary repairs. The mechanic contacted the dealer about the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 42,400.

The contact owns a 2023 Chevrolet Colorado. The contact stated that while driving on several occasions at various speeds, the Forward Collision Avoidance system activated, and the brakes inadvertently engaged. The Forward Collision Avoidance warning light illuminated, with an audible chime and an unknown message displayed. The contact stated that on one occasion the vehicle was pulled off the highway to avoid crashing with another vehicle. The vehicle was restarted and taken to a dealer. The contact received notification of NHTSA Campaign Number: 24V133000 (Electrical System, Forward Collision Avoidance) while getting service, and a system update was performed, and the front camera system was updated. The vehicle was repaired, but the failure returned three days later. The manufacturer was notified of the failure. The failure mileage was approximately 20,000.

My 2023 Chevrolet Colorado ZR2 cannot receive over‑the‑air (OTA) software updates because the gateway module is still running outdated firmware (XXX.mnf).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 vehicle‑wide programming update. However, GM’s system incorrectly shows the bulletin as “closed” for my VIN even though the gateway module was never updated. The truck was sold to me by Tyrell Chevrolet in [XXX] with this safety‑related service update not completed properly. The dealership has confirmed they cannot perform the required update because GM’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 Because the gateway module remains on outdated firmware, the vehicle cannot receive critical OTA updates related to safety, diagnostics, and module stability.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 battery‑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 vehicle’s inability to receive OTA updates. I am filing this complaint so the defect and GM’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)

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. 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 — 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 — 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

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 backward toward the car behind me when it failed to move forward on accelerator input. I narrowly avoided a collision. On a separate occasion, after pressing the accelerator with no response, the vehicle then suddenly lurched forward into cross traffic; repeated presses produced inconsistent, delayed engagement, nearly causing a collision. To climb inclines I now have to hold the brake while applying throttle and slowly release the brake to prevent rollback. These are unpredictable loss-of-control events that create a serious crash risk in traffic. I believe this relates to a known issue affecting the GM 8-speed automatic transmission. The vehicle is currently at a GM dealer and I have an open GM Customer Care case. No crash, fire, or injury has occurred yet, but two near-collisions have.

The blind spot indicator on my truck activates randomly without any vehicle present, and I reported this issue immediately after purchasing it. Despite bringing the truck to Boyd Chevrolet in Henderson, NC multiple times, I am repeatedly told they “can’t duplicate the problem” and therefore cannot repair it. Their only explanation has been that “maybe a future software update will fix it.” No components have ever been replaced to rule out a defective part, and I have no indication that Boyd Chevrolet has escalated the issue to Chevrolet, or anyone else, for further guidance. After nearly three years and 30,000 miles, the problem remains completely unaddressed while my warranty is nearing expiration. This is not a minor inconvenience — it is a serious safety hazard. On several occasions, I have begun changing lanes only for the blind spot indicator to suddenly illuminate, causing me to jerk the wheel to avoid a car that isn’t there. The unexpected false alerts create a dangerous overreaction that puts me and others at risk. I want my truck properly diagnosed and repaired, but I have been unable to find a solution through the dealership. I have detailed service records documenting every visit and every time I reported this issue. At this point, I need meaningful action taken to resolve this ongoing safety concern.

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 I’m only allowed to add a specific mileage and speed below, I’ll note here that it’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.
