2018 Chevrolet Colorado

The contact owns a 2018 Chevrolet Colorado. The contact stated while driving 30-35 MPH, the contact smelled an abnormally strong fuel odor. The odor became more intense while driving. The contact stated upon arriving at the residence, the fuel gauge indicated that the fuel tank was empty. Additionally, the contact noticed a puddle of gasoline underneath the vehicle. There was no warning light illuminated. The vehicle was towed to the dealer, who informed the contact that the failure could be related to the fuel pump. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 52,000.

I along with other people who own this model of truck with the diesel engine around 60,000 to 70,000 Miles have part number 55488542 which is the fuel feed line that rubs up against the AC line and starts to leak fuel. https://www.coloradofans.com/threads/2016-diesel-canyon-severe-fuel-leak.410108/ I along with others have numerous complaints to the Chevy dealership they said this is a common issue because of the type of line that was used and placement that it rubs up and down and since it's a diesel and vibrates a lot and basically the hose is going against the AC Muffler which is a canister and rubs it until there is a hole from rubbing. The link I added to this is one of many. This is dangerous it is fuel it is pouring out and it is in contact with hot parts of the engine

On 4/19/2023, upon turning on the truck, putting it into gear and starting to very slowly move forward a Power Steering Warning/Drive with caution came on. There was no power steering and it required driving very carefully because of the inability to make turns. The truck had to go in for service. Power steering is not covered under the power train warranty, which you would think it should be. The repair required a motor kit, steering gear, belt and reprogram/sensor reset. The truck had less than 40,000 miles on it, and it cost $1533.00

UNABLE TO REMOVE KEY FROM IGNITION SWITCH. ENGINE SHUTS OFF, BUT IGNITION IS STILL ON. IN SHORT TIME THE BATTERY GOES DEAD. PER THE DEALER, THE CUSTOMER NEEDS TO LIFT HOOD AND DISCONNECT NEGATIVE BATTERY CABLE TO PREVENT THE BATTERY FROM DYING AND THE VEHICLE NEEDING TOWING. MOST CUSTOMERS UNDER THE HOOD WITH WRENCHES IS A DANGEROUS SITUATION. PER THE INTERNET THIS IS COMMON WITH THIS VEHICLE, AND THE DEALER FIX IS NOT A SURE CURE. GM NEEDS TO INVESTIGATE AND COME UP WITH A PERMANENT FIX THAT DOES NOT LET CUSTOMERS STRANDED, CARRYING WRENCHES, AND WORKING UNDER THE HOOD TO KEEP GOING, ESPECIALLY AT NIGHT.

Power steering unexpectedly toggled on and off very quickly causing very uneven cornering. After this the truck then drove normally for a couple of miles before happening again at slow speed. Mechanic was able to recreate but due to the intermittent nature cannot diagnose it. Seems like there was an issue with 2015/2016 Colorado's that sounds similar with a faulty electrical connection. Have gone 1 day now without the issue repeating but unsure if/when it will happen again.

clunking in the transmission, when slowing down it feels like you got rear-ended. Then when accelerating from a stop the transmission seems to slip and then catch and then engages and shoots you forward, feels like it surges forward. TSB to replace the transmission fluid was done at about 18k miles, it didn't fix its still doing it now. It did it since day one from the factory and the TSB didn't correct it.
