2019 Chevrolet Colorado

When driving at a slow speed truck seemed to die down and not want to shift to next gears. Truck appeared to shake when pressing on the gas lightly.

The vehicle experienced severe transmission hesitation, rough shifting, and shuddering early on, which was brought to a Chevrolet dealership under factory warranty at 16,875 miles (April 2021). The issue was reproduced by the dealer at that time. The transmission has now suffered a complete failure at 97,277 miles, creating an immediate driving and safety hazard due to loss of propulsion while operating the vehicle. The failed transmission and vehicle are currently available for inspection upon request.

Transmission is shuddering, I had a transmission flush done, and a tune up, and neither helped. I am concerned the transmission is going to go out while driving, especially in a busy intersection and cause an accident. I have had problems with the vehicle no accelerating when need going uphill to get out of the way of traffic when turning. Problem is duplicated every day until I can get it fixed. It has been looked at by a dealership and other personal mechanic shops. No lights on the dash have appeared.

The contact owns a 2019 Chevrolet Colorado. The contact stated that while coming to a stop, the check engine warning light illuminated, and the fuel gauge went from full to empty. The vehicle was taken to the dealer, who replaced the fuel pump control module. The contact stated that his two son-in-law's vehicles, which were the same year, make, and model, also had the fuel pump control module failure. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 60,000.

Failure of Torque Converter. Transmission flushed. May or may not work. Retest after 200 miles. If failure continues, replace entire Torque Converter.

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 Om

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.

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.
