FUEL/PROPULSION SYSTEM — Filed 07/04/2026

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.

ENGINE — Filed 02/09/2026

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

SERVICE BRAKES — Filed 02/18/2026

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.

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.

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.
