STEERING, ELECTRICAL SYSTEM
Loss of power steering, Truck repaired by GM dealer, he stated it was the same failure mode described in Recall notice N2023254 10. The repair even though the same as the previous failures was not covered by GM because my VIN was not in GMs recall notice. Looking at this website there a number of reports of power steering failures for later model Colorado and Canyons that were not covered by the recall. Either GMs fix was not effective, or they did not select the right VIN population. So the Power steering failure repair on my truck even though it is the same failure mode as the previous recall was not covered by GM.

POWER TRAIN
I purchased the truck at the end of March 2025. Within a few weeks I was noticing different issues in the transmission. It would occasionally shudder, have jerky or long shifts, would jump gears and lose power. The shudder was random but mostly on the highway, the jerky or long shifts would mostly occur when the egjne was cold and more often in cold weather. The lose of power and jumping gears would occur when towing and when I was in the mountains, once losing power as I was turning onto a major highway. I took the truck in three times to get diagnosed but they couldnt replicate the issue or find a code. I finally decided to pay for a flush with the fluid that was recommended by a TSB. After the flush the issues were then replicated by the service techs. I have an extended warranty. The representative then inspected the truck and found the same issues and approved a transmission replacement. I took the truck in on June 22nd 2026. As of July 21 the dealership is still waiting for the replacement transmission to be shipped from GM.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION
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Chevrolet Colorado ZR2 cannot receive over‑the‑air (OTA) software updates because the gateway module is still running outdated firmware (XXX.mnf).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)

STEERING
While driving 40-45 mph on a curvy mountain highway, the power steering suddenly stopped working. There was no warning message prior. Once the power steering ceased, a warning message displayed, "Service Stabilitrak". I was left in a situation which was challenging to steer the vehicle, and much more difficult to maneuver at slower speeds and turns. Soon after, I parked the vehicle and shut it off overnight. The next morning the vehicle started with the same warning message "Service Stabilitrak", but the power steering worked fine. I brought the vehicle into Chevrolet dealership service for inspection and diagnosis. Results are attached. The vehicle has not yet been repaired, and is available for inspection. Thank you.

SERVICE BRAKES
While driving downhill nearing a stop sign my wife went to apply the brakes to stop and all she had was an extremely hard brake pedal. She panicked that she “no brakes.” She was only going about 20 MPH, and was able to stop the vehicle but it took an extraordinary amount of effort to do so. Had she had to make a sudden stop for a child, another person, or something else, she would not have been able to stop without negative consequences including possible death. There were no warning signs, vehicle pulled out of driveway and brakes were normal. Less than 10 seconds later no more power brakes. The vehicle had the vacuum pump seize which eliminated the power boost and the pump is operated by the exhaust camshaft which also got damaged and needs replaced. Chevy dealership estimated the repair at $2,600. Upon researching the vacuum pump, this is a common failure on multiple GM vehicles resulting in sudden brake loss. The vacuum pump should have been designed with a shear pin, so that if it fails the camshaft does not get damaged. Had the vacuum pump been properly designed and it was the only failing part, the repair cost would be $500 versus $2,600. Also, there should have been a temporary backup system so you would not lose power boost.

STEERING
My 2015 Colorado has begun to periodically lose power steering. I have now several times been driving. I here a warning ding and a warning on the dash, then my power steering is completely gone. Steering becomes very difficult. This is a significant safety issue. Once I am able to safely pull out of traffic, and restart the truck, the power steering returns.

UNKNOWN OR OTHER
!!Vehicle Safety Complaint!! I am experiencing a serious safety issue with my 2016 Chevrolet Colorado involving the power steering system. On a regular basis, I receive dashboard warnings including "StabiliTrak Not Working," and "Service Power Steering." Shortly after these warnings appear, the power steering fails while I am driving. When this occurs, I must use significant force to turn the steering wheel in order to maintain control of the vehicle and make turns. When I pull over, turn off engine, open my driver door and restart the engine, it appears to have resolved and works fine. This creates an extremely dangerous driving condition. I am concerned that one day I may not be able to turn quickly or forcefully enough to avoid an accident, potentially resulting in a collision, injury, or death. I always have my children in the vehicle with me. NHTSA please investigate and fix this issue!

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
My 2018 Chevrolet Colorado diesel has had repeated diesel emissions/DPF-related failures that cause the vehicle to enter reduced-power or limp mode. This is a safety issue because the truck suddenly loses power and cannot accelerate normally. The most serious incident occurred while driving over Santiam Pass in Oregon. The vehicle went into reduced-power/limp mode on a mountain highway, leaving me unable to maintain normal speed or accelerate safely. I lost power needed to pass traffic and had limited ability to respond to road conditions. The problem has happened several times. It has also occurred while I was towing my boat, which left me unable to continue the trip safely and created a hazardous situation because the truck could not maintain normal towing power. The issue appears related to the diesel particulate filter/emissions system and repeated DPF/regen or exhaust aftertreatment problems. I am concerned that a design, calibration, or emissions-system defect is causing sudden power reduction during normal driving and towing. This creates an unreasonable safety risk, especially on mountain passes, two-lane highways, and while towing. I am requesting that NHTSA review this as a potential safety defect involving the 2018 Chevrolet Colorado diesel DPF/emissions system and reduced-engine-power strategy. I am also requesting that this complaint be considered with any similar complaints, recalls, technical service bulletins, or emissions campaigns related to DPF regeneration, particulate matter sensor diagnostics, reduced engine power, or limp mode on the 2.8L Duramax Chevrolet Colorado.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
VIN: [XXX]. 2019 Chevy Colorado, ~115,000 mi. FAILED COMPONENT: Vacuum pump failed internally; debris damaged the exhaust camshaft. Pump is cam-driven with no shear pin, so seizure cuts brake assist AND sends metal debris into the engine. Truck/parts are at Chapman Chevrolet, Tempe AZ, available for inspection. SAFETY RISK: On XXX, brake pedal suddenly lost assist while my son merged onto XXX from [XXX]. Pedal effort/stopping distance increased with no warning - high risk of collision merging into highway traffic. CONFIRMED BY DEALER: Yes. Chapman Chevrolet confirmed vacuum pump failure and camshaft damage, consistent with GM TSB 21-NA-268 (drive-lug failure). OTHER INSPECTIONS: Dealer only so far; not yet by GM, police, or insurance. Available if needed. PRIOR SYMPTOMS: None. There were no warning lamps, messages, or other symptoms prior to the sudden brake assist failure on 7/1/26. This is a known failure mode on GM's cam-driven vacuum pump (TSB 21-NA-268; Special Coverage XXX covers 2014-2017 trucks/SUVs but not this 2019 Colorado despite same design). Requesting investigation into whether this is an unaddressed defect on 2018-2019+ Colorado/Canyon 2.5L trucks, and whether recall/extended coverage is warranted.
