2023 Chevrolet Colorado Complaints

ELECTRICAL SYSTEM — Filed 09/24/2026

While driving on approximately September 24, 2026, the instrument cluster and infotainment screens went completely black — total loss of speedometer, gauges, warning indicators, and all readouts. The screens restarted on their own after a few minutes. Since then, on startup the screens remain completely black until the 12V battery is disconnected and reconnected, which temporarily restores them before the blackout recurs. This has happened 4 times total at approximately 50,000 miles. No crash or injury occurred. This is a safety concern because the driver loses the speedometer and all warning indicators while driving. The vehicle is currently at the dealership for diagnosis of this issue (Group 1 GMC Westside, 955 Crockett St, El Paso, TX 79922) and had not been seen by a dealer for this issue before today.

After shifting to drive the vehicle had no brakes. A week or so earlier the check engine light came on. Messages on the screen said brake system failure along with other messages. Took to dealership, an update was installed. Last Wednesday engine light reappeared with the same messages but didn’t have time to return it to the dealership so parked it until today. Today was the brake failure. Returned to dealership, they replaced the battery and said the brake issue is fixed. I’m not convinced this fixed the issue and believe this could get someone seriously injured or killed.

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.

EXTERIOR LIGHTING — Filed 09/01/2026

Exterior headlamp surface coating/finish is delaminating/peeling from the OEM headlamp assembly. Dull headlamps pose safety risk as visibility is dimished. GM does not want to warranty defect, no reason given.

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.

ELECTRICAL SYSTEM,LANE DEPARTURE — Filed 07/10/2026

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)

POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE — Filed 02/01/2026

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.

ELECTRICAL SYSTEM,ENGINE — Filed 05/15/2026

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

LANE DEPARTURE — Filed 07/24/2023

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.

SERVICE BRAKES — Filed 03/16/2026

My 2023 Chevy Colorado developed a rear brake squeal when backing up at approximately 20,000 miles. The dealer found nothing wrong at my next appointment. By 30,000 miles, the rear pads and rotors required replacement, at partial cost to me. The new rear brakes are already squealing again after just a few thousand miles. This isn't an isolated issue. A Chevy Colorado forum I follow has documented multiple owners experiencing the same pattern: rear brake squealing beginning around 20,000 miles, followed by premature pad and rotor failure shortly after. Notably, front brake wear is normal across all reported cases, including my own, pointing directly to a rear-specific defect rather than general driving habits or conditions. The rear brakes on the 2023 Chevy Colorado appear to be failing well ahead of any reasonable service interval, and the consistency of this pattern across multiple owners strongly suggests a systemic problem.

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.

ENGINE — Filed 05/18/2026

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 recall.

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!! This time they are saying what it really is, The Radiator Hose FAILURE, since the vehicle is only 3 years old but over the 36k mile WARRANTY, they will NOT fix! failure on their part.

FORWARD COLLISION AVOIDANCE — Filed 04/26/2026

The automated emergency breaking system has been triggered unintentionally twice traveling at speeds of 50 miles per hour. There was no vehicle or object that entered our path. We were traveling behind cars at least three car lengths behind that remained at the same speed. Had there been vehicles behind us, we would have been rear ended at high speeds as the truck came to almost a complete stop on its own immediately.

ELECTRICAL SYSTEM,LANE DEPARTURE — Filed 04/17/2026

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.

FORWARD COLLISION AVOIDANCE — Filed 04/17/2026

Traveling approximately 45 mph on a main road and brakes automatically engaged causing vehicle to abruptly stop. This due to faulty Automatic Emergency Braking system that has allegedly already been repaired with a software update. My child and I were in the vehicle and had another vehicle been directly behind us or even oncoming we would have likely been involved in a collision. There was no warning that came on other than the red flashing lights and beeping that engaged the same time as the automatic braking. I will likely have to go to seek medical care for soreness in my neck and back from the jarring of my body from the abrupt stop. Waiting to hear if daughter is feeling any pain as well, as mine onset through the day after the incident.

3 different issues 1. Automatic emergency braking: Was driving and truck slammed brakes twice at 55 mph to 15mph There was no cars or people anywhere around truck when it happened. The jolt was so bad my neck and my wrist hurt for 3 to 4 days, If there was it would have caused an accident. Took truck in twice once to for recall and 2nd for the brakes slamming. Chevy said they couldnt make it happen again so they cant fix it. I explained it didnt happen for over 11,000 miles so how I just have to wait until it happens again. The light and sound still goes off randomly but brakes haven't slammed yet. Very dangerous this really puts mine and others at risk. 2. Windows don't always go down Part has been on order may still waiting Aug 11, 2024 3. Recently truck won't start battery dead. Going to take in tomorrow. I reached out to gm due to chevy dealer said they are the only ones that can fix issue. That didn't work either. I still have a brand new deg Effective truck. Don't know what else to do. Lawyer says to take it in 2 more times then they can start a case. All I want is it fixed specially when I bought it new.

Dash cluster initially went blank while driving and there was no speedometer or console. The vehicle alarm was also reported as going off in the middle of the night without anything around the vehicle. I took it into the dealership and they replaced several parts including the dash and radio components. They also performed a front camera recall repair. A few weeks later after driving around 250 more miles, we were driving in traffic around 50 mph when all of a sudden the vehicle came to a complete stop with no foot on the brake and injured my husbands neck and my wrists from how abrupt the stop was. The vehicle basically shut down and had to be restarted several times to get it to start back up again. Had roadside assistance tow it into the dealership again and they said that it happened during their test drive of the vehicle as well and was beeping and stopping at shadows on the ground. They drove it about 65 miles before it did it again. They returned the vehicle to us, unable to repair the issue and the GM technical engineer told them to just turn off all of the safety features in the console and that I would have to make sure they were turned off before driving the vehicle every time or if it lost power. They turned off the emergency braking controls with this action. Asked me to also adjust the gap to mid for object detection. They replaced the front camera with the recall and it still did not fix the issue. They told me that my truck does not have adaptive cruise control but the devices were acting like I did. I don't know if this is true or it is just another excuse. Note- This is the 2nd Chevy Colorado that i have had in 6 months with same issues as the dealer replaced the first lemon after 2 months.

Got a letter that my vehicle had a recall on adas system. Took it in to get fixed. A week later was driving home from work on a straight away and Trucks brakes slammed from 50 to 15 then let up. The impact was like Someone hitting me from behind. Strained my neck and wrist. Because I was in shock it happened so looked around and there was only one truck 2 lanes on side of road. When the brake released I started driving again. 3 min later It then happened again. I was scared it would happen again so I drove home real slow. We took it back in to get fixed on [XXX] at the chevy service in hemet. Roger used a sensor reader showing brakes locked up twice. They said they checked it and because there was no issues showing. They didn't fix it. Roger said they drove it 10 miles and nothing happened I explained I have driven it 11000 miles and nothing happened until Last week. How can they send me away without fixing a very dangerous issue. As of today [XXX] it can still happen. I was lucky there was no cars behind me that day it would be a different story. Now I have to call GM to try and get them to tell hemet chevy to fix it so no one gets killed or hurt next time it happens. What ever happened to fixing the issue?

Vehicle at random moments will automatically make the vehicle brake to a complete stop. Very dangerous thing to happen and has happened about 5 times and one time my vehicle was side swiped as the vehicle maneuvered away from and hit my rear right side to avoid my braking on the freeway.

FORWARD COLLISION AVOIDANCE — Filed 02/06/2024

The Automatic Emergency Braking System failed me today. The truck is available for inspection. I was driving at about 45 mph, when a car pulled out from a driveway infront of me when it probably should have waited, but there was still time for me to brake safely. I started to apply the brakes and the truck slammed on the brakes, no red lights on the dash flashing, no warning beep. I pulled my foot off the brake because I wasn't sure what was happening but, the truck slammed the brakes to a full STOP.. instant stop! If there had been a car behind me, I would most certainly have been rear ended. The seat belt locked up, my body was thrashed forward twice because of the quick slow down and the stop. I'm sore, scared and not sure what to do. This isn't something that can be recreated without putting someone else in danger. This is not a safety feature, it's an accident waiting to happen!
