2017 Chevrolet Colorado

There is a major fuel line leak just before the high pressure fuel pump. It appears that the fuel line aggressively rubbed against an A/C line component (looks like a muffler/canister). This rubbing created a huge hole in the high pressure fuel line, causing diesel to spray everywhere on the driver side of the engine compartment. This causes a massive safety issue due to diesel fuel uncontrollably spraying onto hot engine components. In my own research, this seems to be a known problem for GM. I believe there is a TSB published for this exact problem, but I have yet to find the document online. This needs to be an official recalled item ASAP.

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

On Wednesday, February 18th, I was driving on the freeway, usual heavy traffic right off of it at 5:00pm. When exiting and merging onto the street, I pressed on my break to slow down and meet the speed of traffic, but my breaks felt hard, I struggled pressing it down, and my car wasn’t slowing down. I was able to swerve off into a dirt patch next to the road. Then I panicked, unable to find where my emergency break was, I put my car in park and it eventually came to a stop. I then took the car to the dealership, and they’ve told me that the vacuum pump needs a replacement. The car has currently been at the dealership for a week and a half and there still seems to be no solution. I’ve reached out to General Motors and with the responses they’ve given me, it feels like they the know what’s going on but have thus far given me the run around. They say they’ve reached out to the dealership, but when I mention it to my dealership advisor, they say they haven’t heard anything.

If I hadn't maintained a safe following distance, I wouldn't have been able to stop in time and I would have crashed into other vehicle. I arrived on home safe but nervous. At next day, Dec 22th turn on my colorado and appears same message, KM 47245km I turned off and tried turn on again but it not turn on, battery low message appeared, then I had to have my Colorado towed to the car dealership.

October 2025----problem with 2017 Chevrolet Colorado WT with 2.5L engine and 6 speed automatic. It has 57,000 miles on it. Original owner--bought new. "StabiliTrak" warning light came on when I first started the pickup in the morning and stayed on. Then a message appeared saying that there could be a steering issue or a control issue operating the pickup and to take it to the dealer for service. Colorado starts normally and runs normally. Only issue is the warning light for the StabiliTrak is on constantly. I read in the manual that TCS(traction control system) and the StabiliTrak system have been disabled. The owner's manual states "The vehicle is safe to drive; however, you do not have the benefit of StabiliTrak, so reduce your speed and drive accordingly." Have a dealer service the system. I have had no safety issues or risky situations. Have about 300 miles added since it occurred. It has not been inspected yet by a dealer.

I believe there should be a recall for the KNOWN chafing issues for the engine wire harness. This happened to my truck this past year around September/November of 2024 and didn't get a fix until June 25. There are TSB's out for other models as well as mine regarding the wire chaffing. it shorts out intermittently and cause all kinds of warning lights to go off, (check stabilitrak, check 4x4, etc) the vehicle usually did a bunch of stop and go jerks when it would do this then go into limp mode. I even had it stall completely on me and the steering wheel locked up. I think they had to disconnect the battery or something to get the key out. I've been on several different forum pages trying to find the issue and I have seen it happen on relatively new vehicles as well. Lucky for them they are under warranty but dealers still giving them a hard time on this issue. I believe this poses a safety issue and there should be a recall on this. Besides that, no one should have a perfectly good vehicle and have to pay 4000-7000 dollars to replace a wire harness because of a manufacturer design defect which seems will eventually cause this issue though it had happened on newer models as well. the bulletin #specific to my vehicle is PIT5626D but there are other bulletins for other engines/models

The heating cooling blend door broke as it's made of cheap plastic. Doing research on this defect it's very common ...in this year vehicle as well as in the gmc canyon...it's a manufacturer defect. And makes it impossible to defrost/defog your windshield without fixing it...and average cost to replace is 1700.00- 2300.00...due to labor cost...part itself only costs around 100.00....that's an astronomical amount of money to fix something...that is a defect and you can't safely drive without it!

I was driving to lunch and without warning, my brakes failed when I approached a 4-way stop. With ABS, I was able to stop my vehicle safely in a parking lot. However, the when I turned the vehicle off, it would not start again. The vacuum pump seized and since it is driven by the exhaust camshaft, it destroyed the exhaust camshaft. It's been two weeks and I have been unable to acquire that part. I have been notified by GM parts distributors that the part is on a national supply delay with no firm ETA from GM. It seems to be a very common failure. I have been out of a vehicle for over two weeks because of this failure. I also could have been in a terrible accident since the vacuum pump failed without warning. I have checked chevy forums and several others reported the same issue.

Fuel leak in line. There is a pin hole in the line spewing fuel under pressure when running. The fuel flows down the side of the tank as I reported in Complaint Number 11587383 on May 7th, 2024. Now I have removed the bed to discover said leak. Adding picture of the leak spewing fuel from line, by "P E" lettering on the line This is a major concern as any flame near the vehicle would cause it to go up in flames. The manufacturer should correct this problem. I see no reason why this hard plastic pipe developed a hole. It is product defect.

Truck started having electrical issue after finding a dead squirrel in the engine. Taken to dealership 9/2/2023 and was told the wiring harness needed replacement. Left the truck there for 2.5 months with no repair so we brought the truck home in December 2023 and asked them to call us when they got the part. Had a rainstorm the following day and the truck tried to start itself, wipers running, lights flashing, and smell of something burning. Disconnected the battery and had truck towed to Beach Chevrolet Dealership. Damage was worse than they originally thought and we still needed a new wiring harness. That particular wiring harness has been discontinued by GM and they are unable to find the part anywhere. The truck is still at the dealership and it will be 8 months on May 2, 2024. State Farm refuses to total the truck and we have no idea when our vehicle will be repaired. Have contacted GM customer Disservice repeatedly with no resolution in site. What recourse do we have?

Purchased vehicle new in 2017 with 14 miles. In June 2018 at 17,500 miles vehicle developed a sever transmission shudder. Took the vehicle to the Chevrolet dealership where purchased. They replaced the transmission fluid and torque converter. Now, in July 2023 at 79,000 the transmission shudder has returned. This shudder affects my ability to control the car’s speed, acceleration, and deceleration and increases the risk of collision. Took the vehicle back to a dealership. They now recommend a full transmission replacement at $5,900. They will cover only $237 of the cost since the vehicle is past 5 years and 60,000 miles.

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

I took my 2017 Chevrolet Colorada in for an oil change and when exiting the building I made a sharp left turn at very slow parking lot speed. The steering wheel locked up and was difficult to break loosed. I had the mechanic come out and he drove the Colorada around the building and it locked up on him also. This could be a very life threatening situation had it not been in the parking lot. I drove directly to the Chevrolet dealer to report the problem and they had never heard of this happening. I beg to differ on there statement as I did an Internet search and found numerous problems the same as mine from owners of Colorado, Silverado and GMS pickups. I am actually hesitant to drive this vehicle for fear of have a catastrophic failure causing injury or death. I was at a Jiffylube service center at the time and the certified mechanic drove the vehicle.
