2019 Chevrolet Colorado Engine Problems

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.

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.

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).

The contact owns a 2019 Chevrolet Colorado. The contact's husband stated that while driving 20 MPH, while attempting to turn into a parking lot, and another vehicle was attempting to exit the same parking lot, the brake pedal was depressed; however, the vehicle failed to respond. There were no warning lights illuminated. The contact's husband depressed the brake pedal, the brake pedal seized, and the contact had to veer and downshift to first gear to avoid crashing into the other vehicle. The vehicle was taken to an independent mechanic who diagnosed the vehicle with vacuum pump failure and a fractured part from the vacuum camshaft. The vehicle was not fully repaired. The local dealer was contacted; however, the vehicle was not repaired by the dealer because the vehicle was not under recall and parts were on back order, as per the dealer. The manufacturer was made aware of the failure and referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 130,000.

Engine Light turned on. Fan keeps running for 10-15 minutes after truck is turned off. Went to two different mechanics and it is a thermostat problem. Temperature sensor and thermostat both have gone bad in under 5 years. They have told me it is not a good design and now parts are in back order. This needs a recall.

I purchased my 2019 Chevy Colorado Z71 new in Feb 2019 from a dealership. About two years ago I began having shifting issues from 1st to 2nd gear, it would shudder and seem almost stuck, this would only occur infrequently. Right after I hit 100,000 miles (about a year ago) I have had nothing but issues with the 8 speed transmission, my vehicle is unable to shift from 1st to 2nd without having the shudder occur, it feels like the whole truck is shaking and loses power at acceleration. I took it in for their recommended "service bulletin" which was something that I had to locate myself because GM has not once communicated about there being any kind of shudder issue and they performed a simple flush of the transmission, not the service bulletin recommendation of three flushes and a different fluid. My truck is now in the shop because I am unable to drive it due to this ongoing issue that GM fails to recognize and so far have spent $1,000 attempting to rectify this issue and being told that in order for them to actually perform the service bulletin, it will be another $225 to diagnose the problem, around $500-$700 to perform the service bulletin, and then if that "does not fix the problem", I will have to spend another $900 on a torque converter because that "could" be the issue, the dealership "doesn't know". Then the third fix would be to replace the transmission ($5500-$8500) This has been a known issue since manufacturing and GM is failing to provide adequate assistance to fix a known problem with their 8 speed transmissions. I no longer feel safe to operate my chevy colorado in fear that it could cause serious injury to myself and others due to GM not being able to provide a safe fix to their ongoing issue.

This truck has roughly 41000 miles on it. As I was driving home from work on [XXX], I heard a faint noise and then my truck just lost power and died on the freeway. There were no engine warning lights on and did not want to restart and stay running. After a few times of starting and dying the message on the dash said keep driving engine is in regen. This is a diesel truck and the newer ones have a regeneration that is done with DEF. I was unable to get it off onto the exit, but did get it off the roadway. The vehicle was towed into the shop on February 3rd, 2024. The shop had to order parts and said that it was just a faulty part. I received the truck back on March 14th. I drove it home from the shop and to work for two days putting roughly 100 miles on the truck. On my way home on [XXX] , the truck died again with no warning at all. Same symptoms, just no power and no warning. The truck was towed back to the shop where it still sits today. The problem is there is an issue with this thing dying without any warning at all. The dealer and Chevrolet techs have been unsuccessful in finding the problem. It has been almost 6 months in the shop with literally no idea of what is wrong. I feel this is a serious safety issue that could leave people or families stranded without any warning or idea of how to repair. I feel this should be investigated and brought to someone's attention. I have contacted Chevrolet, but unfortunately they have left everything up to the dealership. The dealer is Auburn Chevrolet in Auburn, WA.

Dec 28, 2023

We purchased a 2019 Chevrolet Colorado December 2022. Beginning in January 2023 to current month July 2023 the vehicle has been at the dealership 4 times for the same occurrence: SERVICE STABILITRAK and ENGINE POWER IS REDUCED A warning “ding” sounds (the same noise as seatbelt, door ajar, etc) simultaneously with the messages “SERVICE STABILITRAK” and “ENGINE POWER IS REDUCED” The vehicle immediately is jerking or lurching, the engine no longer runs smoothly and is misfiring. The engine power reduced does not allow safe acceleration, and the vehicle is unstable (as it moves it feels like driving over a thousand speed bumps over and over), the engine misfiring is heard from the exhaust and the vehicle is visibly vibrating, on acceleration the maximum speed is 20 mph. All 4 times this has happened while driving the vehicle on highways in traffic. We are left unable to get out of the way of moving traffic, unable to accelerate, change lanes or make turns safely. Three of the four times we had the vehicle towed to the dealership. The last time the vehicle did this fortunately I was near our local dealership and drove it less than a mile so the service people could “witness” what I had been trying to explain what’s been happening with this vehicle. This is a very serious issue! My husband is 75 and very ill. I have to drive him 100+ miles for treatments on a regular basis. We cannot continue to be put in danger because of this vehicle default. We need this problem fixed not only for ourselves but for the safety of others, including unsuspecting drivers and innocent passengers, young, elderly, disabled, some simply misunderstanding our vehicles “failures to perform” in traffic on the roads. A trusted vehicle is very important. A stabile vehicle with sufficient engine power is a must if we are going to put it on the roads. “SERVICE STABILITRAK” and “ENGINE POWER IS REDUCED” is not new. General Motors needs to take action to correct this problem and educate dealers.

As I went around a turn (low speed), the truck lost power steering for about a half of a second. It came back online right away, but caused me to take the turn poorly. At the same time, the engine shut down and all of the lights on the dash went out. I stopped the vehicle, put it in park and restarted the vehicle. Everything then worked as if nothing was wrong. There are not any warning lights. It was as if someone simply turned off the ignition for a minute.
