general problems of the 2017 Chevrolet Colorado

Thermostat is having problems. Fan runs over use and thermostat will not open.

On or about 02/09/2026, the vehicle experienced a catastrophic failure directly related to a known defect identified in technical service bulletin 19-na-066. The engine "sucked" in the oil filter due to a poor design on gm's part. The stand pipe was not present apparently, and must have broken off at some point. This bulletin acknowledges an issue affecting this vehicle platform. This should have been recalled to address this engineering flaw that gm acknowledged in their TSB. Despite multiple attempts and ongoing communication with authorized representatives to have the vehicles engine replaced under an extended warranty, the vehicle was inoperable and unusable, causing significant financial hardship. I owned the vehicle for approximately 5 months and had the vehicle in the shop multiple times for other repair issues that were known per forums from other owners of this model/year of vehicle. I have exhausted all reasonable efforts to resolve this matter through dealership, gm customer service channels, and gm's executive team without satisfactory resolution. As a direct result of this defect and resulting failure, I have incurred the following damages: loss of use of the vehicle ($24,578 purchase price on 09/20/2025) rental and alternative transportation expenses ($90. 58 rental vehicle from 02/12/2026 - 02/14/2026) diminished vehicle value ($24,578 - $12,000 (selling price) = $12,578) out-of-pocket diagnostic and related expenses ($2,036. 50) total loss and seeking reimbursement: $14,705. 08.

2017 Chevrolet Colorado pickup with 58,000 miles. Check engine light came on. Scanner reading by a repair shop indicated a evap issue. I declined the $1200 repair estimate. I paid for diagnosis of problem $200. I repaired the system by "cleaning 2 filters at the beginning of the fuel tank ventilation system. The "primary filter and hose are located in a especially dusty area on the pickup truck and is prong to plugging if regularly driven on rural gravel roads. Nothing in the owner's manual indicates the service is required of this filter. Filter should be relocated to engine bay. Check engine light was reset and has not come back on. Note: this is part of the pollution equipment that stopped working properly before 10yr. Or 100,00 miles.

The contact owns a 2017 Chevrolet Colorado. The contact stated that while driving at 60-65 mph in the mountains and towing a travel trailer, the check engine warning light illuminated, and the brake haul mode turned off. The engine warning light had illuminated over thirty times without towing a trailer. The contact stated that when the engine light was illuminated, the tow-haul feature would shut off. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 90,000.

The vehicle shakes aggressively when you speed up. We took it in and it’s a transmission issue. There have been thousands of similar complaints from other owners but chevy refuses to acknowledge it and issue a recall.

The contact owns a 2017 Chevrolet Colorado. The contact stated that while driving on several occasions at various speeds, the a/c unit stopped working, with the check engine warning light illuminated. On several occasions, while the vehicle was turned off, the cooling fan ran for approximately 2-3 minutes. The vehicle was taken to an independent mechanic where it was diagnosed, and determined that the engine coolant thermostat had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact stated that the seat belt warning light illuminated while the seat was not occupied. While driving at various speeds, the engine overheated. The coolant reservoir was empty, but there was no indication of a leak. The fan was operational, but the vehicle continued to overheat. The vehicle was taken to an independent mechanic, who informed the contact about the operation of the fan. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 110,000.

Exhaust leaks but it doesn’t do it all the time.

From a stop, accelerating has occasionally caused transmission to shudder, limiting power and ability to follow traffic until transmission reengages and power is restored. This creates an unnatural traffic pattern and puts myself at risk. After much research it appears the problem is with the transmission and torque converter. The engine may produce more torque than the transmission can handle. Problem started out infrequently, but has increased in frequency over time. Please reference report #11449007.

My vehicle shutters on highway. I was told by a few chevy representatives that they would help fix it even though it’s out of warranty. This is a known problem across the USA and they should fix it at no charge to customer.

The oil coolant line has just failed for a second time in two years on our 2017 chevy Colorado that only has 50,000 on it. In both cases I was driving down the road and the line ruptured and alarms started going off to shut the engine off. This is very dangerous to have to immediately stop in the middle of the road and then left stranded (especially in the middle of a cold mn winter). The first time this happened the vehicle was under warranty and our dealer towed and fixed the vehicle. The second time, it is just 8 months past the warranty time (still under the warranty mileage limit). This is now a $1200 repair for something that should not be happening any way. This is a known, common issue with gm and they are doing nothing to solve this problem - or even warn their customers of this safety issue. Two catastrophic failures of an essential drive train component in a vehicle with 50,000 miles? also in both cases there was no warning of any kind before it happened. No warning lights or symptoms. It just all of a sudden blew both times and left me stranded on the road.

The contact owns a 2017 Chevrolet Colorado. The contact stated while the vehicle parked, the air condition was activated and there was an abnormal clicking sound coming from the engine. The vehicle was taken to the dealer to be diagnosed. The contact was notified of a failure in cylinder #6. The contact was informed that the engine needed to be replaced. The manufacturer was contacted and agreed to cover 50% of the repair. The failure mileage was 28,208.

2017 Colorado all of a sudden I was just driving down the road going 55mph, and my truck shut off. No warning light just died completely. I almost got rear-ended by the car behind me. I could not start the truck back up at all. If I had been in construction zone someone could have seriously got injured or killed, huge safety issue. I had the truck towed to the chevy dealer, it took the sever days to find out the issue. The wiring harness behind the motor, was rubbing on the fire wall, causing several wires to become exposed and short out. Dealer even if they put a new wiring harness back in it would have the same problem, based off where it is located. I trying to make sure no one gets killed and recall issued. I contacted chevy customer support they didn't seam interested is fixing a safety issue, no there problem after warranty are over.

While traveling down the highway at 70-75 mph a wrist pin failure occurred. This lead to a rod punching a hole in the bottom part of the engine, obviously I lost all engine power and had to coast to the side of the road in traffic. Looking online there are wrist pin studies conducted by geen diesel engineering company that shows obvious manufacturing defect in gm wrist pins. Upon further research I have found that this is a common failure with the 2. 8 liter diesels. I contacted gm they informed me that this is not a documented problem which has set me back about $14,000. I found out that I’m not alone from what I have found it seems to affect 2016-2017 models. I’ve seen failures occurring within 7000 miles.

I have a 2017 chevy Colorado diesel with approximately 50,000 miles where the diesel particulate sensor constantly fails. I had it replaced for the 4th time the last week in January and now its failed again. The code received is a p1476. I will have it replaced for the 5th time next week but according to online Colorado diesel forums this is an endlessly failing piece of equipment. As a consequence many owners are working with after-market tuners to remove this emissions control. The messaging I see online is that this will be an endless expense if I keep my truck beyond the limited emissions warranty. To-date the warranty has covered the repairs(~ $500 each) but the emissions warranty will be expiring soon. I think the NHTSA and epa should force Chevrolet/gm to provide an unlimited emissions warranty. Save that, gm will ignore the problem and many thousand of diesel trucks will have their emissions controls removed.

The contact owns a 2017 Chevrolet Colorado. The contact stated that the key failed to be removed from the ignition switch occasionally. After several attempts with manipulating the gear shifter, the steering wheel, and manually turning the key in the ignition cylinder, the key was extracted from the ignition. The contact took the vehicle to ken ware Chevrolet Buick GMC Cadillac (1595 newmark st, north bend, or 97459, (541) 982-2574) to be diagnosed however, the mechanic was unable to determine the cause of the failure. The failure persisted. The manufacturer was made aware of the failure. The approximate failure mileage 40,000.

The original owner of my vehicle successfully had gm buy back this truck. The nox sensors and wiring harness had been replaced three times which cleared the codes and allowed the vehicle to appear to be in proper working condition. When gm bought the vehicle back from the original owner, gm went through and supposedly "fixed the issue" and branded the title as a manufacturer buyback and put the vehicle back on the market to the general public. I purchased this vehicle knowing all of this and trusting that if gm said they fixed the issue, they had really fixed it. Now I am a year into ownership and this vehicle is still under warranty, however this is the third time that this same exact thing that the original owner had an issue with has surfaced. The vehicle speed is limited when this occurs making the vehicle dangerous to drive on the roads. The vehicle is always in motion when when this occurs and usually on an interstate far from the dealership.

The truck shudders while accelerating.

Twice now my 2017 w/~41000 miles has gone into instant, no warning or grace period, but an instant drop to a forced 10 mph in the middle of traffic, this last time on a highway with no shoulders during rush hour. The three codes thrown the first time (I don't have the codes from the second time but the dealer is ordering a new ecm based on the u0401 code): � rc (radio controls): b1325 - control module power circuit - low voltage � ebcm (electronic brake control module): u0401 - invalid data received from engine control module - invalid data � ecm (engine control module) p200c diesel particulate filter (dpf) high temperature along with the codes the check engine, stablitrak, and traction control lights came on - however braking was not affected! regardless, this programmed 'limp' mode is insanely reckless with total disregard for the safety and welfare of the vehicle occupants, there is absolutely no safe place or reason to deliberately cripple a vehicle while in traffic! some european manufactures at least give you a warning with several engine restarts to let you drive normally to safety and then a dealer for service � but apparently emissions laws in the us take precedence over human life. Limp mode can be disabled for emergency vehicles but the dealership told me it was illegal for them to do it for me. The dealership has been great but limited to what they can do because of gm requirements. They are currently looking into the problem and has ordered a new ecm as a second phase in troubleshooting the issue (first was reprogramming the ecm) however there is still no excuse for forcing a vehicle into limp-mode while in use - I have lost all faith in this vehicle and gm and cannot trust it for my own yet families safe use.
