2023 Chevrolet Colorado

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Chevrolet Colorado ZR2 cannot receive over‑the‑air (OTA) software updates because the gateway module is still running outdated firmware (XXX.mnf).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 Because the gateway module remains on outdated firmware, the vehicle cannot receive critical OTA updates related to safety, diagnostics, and module stability.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)

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.

Blind spot monitoring system consistently malfunctions, illuminating the driver mirror warning light when no other vehicles are present. It occurs more frequently after dark, which flickers the bright light continuously, or leaves it on constantly, creating a significant distraction and mistrust of the systems reliability. Dealer had no recommendation for fix.

1. Other: Turn signal - when turning right with the signal activated, once you straighten the wheel, the turn signal stalk will reset to the middle but will activate the left turn signal. 2. Adaptive cruise control - For no reason the brakes will activate, there is no vehicle in front and the windshield is clean. 3. Blind spot warning - These BSW indicators will go off at random with no vehicles beside mine. This occurs more at night, but does happen during the day. When this happens at night the yellow indicator is so bright that you cannot even see what might (or is not) in your blind spot. This faulty indicator is going to get someone hurt as other drivers with the same issue might over correct.

Side object sensors go off frequently when no vehicles are there on both sides of vehicle. Additionally when passing vehicles the side object sensors only detect vehicles about 40% of the time. The side object sensors will double flash when no vehicles are there and fight me when changing lanes when lane assist is on. I have video of the false alerts and non detection incidents.

Within in the two weeks of owning my truck the forward collision warning has alerted and forcefully slammed my breaks to a complete stop. One going 75 mph on the highway and once during normal in town driving. I have deactivated the system ever since. I did make my dealership aware but they just said they aren't aware of any issues. The driver side blind spot monitor constantly gives ghost alerts when it is dark.

The blind spot warning will light up on the passenger side randomly when no other vehicle is present. If changing lanes while this occurs the vehicle will try to force you back into the lane you are trying to depart from. This false warning could potentially result in an accident. The dealership has so far been unable to recreate the problem, but this was only attempted once. The dealership did state that this is not the first time this issue has been brought to their attention. I have also found numerous complaints online regarding the exact same problem. No other warning lights have appeared. The vehicle has not been inspected by the manufacturer or others besides the dealership.
