2019 Chevrolet Colorado

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.

The infotainment system is not functioning. The screen will come on as I turn on the truck, then it goes blank. Sometimes it flashes and then goes black. I cannot use any of my apps or connect to Apple CarPlay. This has been going on for months now. I have complained to Chevrolet and the dealership. They have failed to provide a solution. This truck only has 35,000 miles on it. We can no longer take it on trips because we have no navigation, especially in areas where wi-fi may be hard to connect to by just our phones. We have followed all the trouble shooting provided in the Chevy app or online and nothing helps.

I purchased my truck from Karl Chevrolet in Ankeny, IA around September of 2019. Approximately 1.5 years after purchasing the vehicle, I began having issues with my infotainment system intermittently resetting itself while I was driving. On or about the end of 2021 (after this had occurred a few time), I brought the truck into the Karl Chevrolet in Ankeny, IA, as it seemed to become more frequent of an occurrence. The technician told me that this thing happens all the time with the infotainment systems and it was nothing to be concerned about and because it was intermittent, they may not be able to identify the issue unless it was actively occurring and I was told to come back in if it continued to happen. Shortly after, I had moved to [XXX] in April of 2022, I began to have more frequent issues with the infotainment system randomly resetting and eventually it began impacting phone calls, where people would cut in and out or disconnect, beginning to cause even more of a safety and distraction issue. After conducting some of my own research, I learned that I was not the only one that had issues with the infotainment system in the 2019 Colorado and that GM had published several Technical Service Bulletins (TSBs) regarding the infotainment system, and there had been a class action lawsuit, [XXX] , et al. v. General Motors LLC, that covers the same issues I am having. On January 29, 2025, after the issue progressively getting worse, I took the truck to Gregg Young Chevrolet in Omaha, NE. After conducting a diagnosis they verbally confirmed there were TSBs regarding radio issues that after contacting the GM service center, GM's response was to replace the radio. This was to be at my own cost however, considering GM confirmed through TSBs there are issues with the infotainment system, coupled with safety concerns around distracted driving, I felt compelled to make this complaint.

Torque converter shutter makes vehicle lunge forward while driving. Feels like something pushes you from behind. On a wet road and especially in a curve this could cause rear wheels to slide.

In and out of the shop for the last 3.5 years (Warranty is expired now) with multiple engin codes (CEL). Most having to do with the fuel delivery systems. Most common P026D, and P1089. It has been in the shop at least 6 or more times. GM won't stand by their product. Since the warranty ended I've put mor than $4,000 in to repairs for this and now I'm told it will cost me anouther $6000 to $7000 to repair. I bout this truck used with 60,000 miles on it and paid cash $50,000 to the dealer the originally sold it to the previous owner. I just want them to fix the issue once and for all. To date they have just thrown parts at it but it never fixes the problem. They have changed the MAP sensor, the fuel rail and pressure regulator, the injectors, and they've re-wired part of the wiring harness. None of this has solved the issues.

Experience hesitation at a stop and shuddering at certain speed

I experienced shuttering when accelerating, leaving Treasure Island garage. I got on the freeway and drove 11 miles. I experienced shuttering again after waiting at a red light. I experienced final shuttering after reaching another red light. Had it towed to the dealership and was told that the transmission was no longer operational. Truck was 5.5 years old with a little over 60k miles. I was on the way to pick up my daughter and thankfully, she was not in the truck when this occurred. Truck did routine maintenance at Chevy dealerships only. Fairway for the majority and Findlay the final year of its life.

I was travelling at approximately 32 miles per hour when I rear ended a vehicle that was in front of me, the vehicle in front of me was stopped. The airbags did not deploy in my vehicle. Damage to the vehicle was substantial enough to declare the vehicle a total loss.

The transmission is starting to shutter at high speeds and not shift as intended.

The contact's husband owned a 2019 Chevrolet Colorado. The contact stated that while her husband was driving and she was a passenger, their vehicle shuddered and then lost power at approximately 55 MPH. The vehicle was guided to the side of the road, where the contact and her husband noticed smoke emerging near the gear shift. For safety reasons, they both exited the vehicle and moved away from it. The contact then observed flames appearing between the driver's side of the cab and the bed of the vehicle, which quickly burst into flames. Another motorist attempted to extinguish the fire with an extinguisher, but it ran out before the fire could be contained, and the vehicle became fully engulfed in flames. Although the police were called, a formal report was not filed. The fire department arrived and extinguished the fire. The manufacturer was not notified of the failure. The failure mileage was approximately 41,000.

The contact owns a 2019 Chevrolet Colorado. The contact stated that while reversing, the rearview camera image was blank, and the message "Service Camera" was displayed. The contact noticed that upon closing the tailgate with the key, the rearview camera image failed to display while reversing. The contact stated that the failure was initially occurring intermittently, but the rearview camera later became inoperable. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 42,000.

Transmission shakes, lurchers when driving, transmission stalls then engages abruptly at low speed and highway speed.

The contact owns a 2019 Chevrolet Colorado. The contact stated that while the vehicle was parked, the contact saw oil on the ground underneath the vehicle. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with a leaking valve cover gasket. The contact was informed that the valve cover gasket needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the independent where it was diagnosed with a failed CAM shaft carrier gasket. The contact was informed that the CAM shaft carrier gasket needed to be replaced. The vehicle was not repaired. The dealer was made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 112,000.

The contact owns a 2019 Chevrolet Colorado. The contact stated that while driving at various speeds, there was an abnormal rumbling sound coming from the front of the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired due to the part not being available. The manufacturer was notified of the failure. The failure mileage was approximately 80,000.

Transmission Component: M5T: TRANSMISSION AUTO 8 SPD, 8L45 available for inspection. The vehicle shakes badly and shudders during acceleration and causes a brief inability to accelerate, often at higher speeds and with a great deal of rumbling and vibration. No other warning lamps, messages, or symptoms. The problem first appeared about 2 months ago. I recognized it as a persistent problem, and I was no longer comfortable driving the vehicle and feared that it would shut down while driving. I took my vehicle for diagnostic and maintenance at a local service center who also noticed that the transfer case "is making an unusual squeaking noise when driving". I was then notified that this is a known problem with this vehicle make and model for 2019 and referred here to file a complaint. Having less than 60K miles on this vehicle, I was referred to the dealership for possible next steps.

Unable to remove ignition key. Sticks in the accessory's mode. This happens periodically and I can eventually get key out by continually moving shifter back and forth until key can be removed. Concerned that eventually this won't work. I noticed that this is the main complaint on the Chevrolet Colorado.

The infotainment center goes out, then comes on on a frequent basis causing the loss of navigation system through CarPlay and now will not even connect to CarPlay also loses backup camera. In addition I have noted that when the blinker is on to signal a turn, it will stop the blinker system when the infotainment center goes out, which is a safety concern with the use of blinkers to signal approaching rear traffic to the vehicle. I have contacted the dealer and also see there’s an infotainment bulletin out. I have not had a response from the dealership as of this report. I am also a certified safety professional, and the loss of turn signal in conjunction with the infotainment center outage raises a safety concern in my opinion. This has been an ongoing issue with the system for the last year or so and has progressively gotten worse to the point that the screen now goes out every minute or so for 5 to 30 seconds and now CarPlay will no longer connect to phone for navigation. The constant screen going black started within the last 30 days of June 2025.

Vehicle will make a loud humming sound going 50 to 65mph and when letting off the gas pedal. It will stop when pressing on the gas pedal or when vehicle slows down below 50mph

No warning lights or messages or anything. Blown head gasket and a large amount of coolant in the oil. I have an appointment to take it to a dealership the end of this week

My 2019 Chevrolet Colorado, equipped with the 3.6L LGZ engine, recently triggered a P0024 diagnostic trouble code. This code indicates a failure of the Bank 2 exhaust camshaft position actuator solenoid, a critical part of the variable valve timing (VVT) system. After researching, I discovered that General Motors has issued Special Coverage N232430470 for this exact issue on the 2020 Chevrolet Colorado, which uses the same LGZ engine and solenoid system. Despite the identical failure and engine design, my vehicle is not currently included in the coverage. I believe this reflects a systemic defect that affects multiple model years — not just 2020 — and that GM is choosing to limit coverage unfairly. This failure can result in check engine warnings, drivability issues, reduced fuel economy, and possibly emissions system non-compliance. I am requesting NHTSA to investigate whether this VVT solenoid issue warrants a broader recall or special coverage extension across model years with the LGZ engine (including 2019).
