2018 CHEVROLET COLORADO Complaints

Truck bought in United States for use in US. All dash displays ( child or person in back seat or passenger seat, and gauges, emergency or vital messages, warnings etc) are in a foreign language. I only speak and read english. In addition, may go into mode where it changes channel and volume every few seconds which is distracting. Chevrolet dealer (Valmark) says they want 100-200 usd to diagnose and 2000.00 to replace. Reset did not fix. Vehicles for US should be in common language. Chevy should diagnose and repair free of charge. Screen is locked/frozen and cannot be accessed. Spoke with Ian at chevy hdqtrs who said diagnose fee is up to dealer, i will have to pay. Chevy forums say common problem and chevy won’t repair.

The driver side seat belt does not immediately latch when placed in the seat belt housing. To secure the seat belt the driver must keep placing the seat belt latch into the housing multiple times in order for the latch to secure. When brought to the attention of a local Chevrolet Service Center, their response was to pay >$400 to replace the seat belt housing (near the seat). The service center is Lamb Chevrolet in Prescott, Arizona.

He wiring harness to the 4wd kept coming on which wouldn’t allow me to ingage. Mountain Chevy citified mechanic found a chafing on the wiring harness. After filing it my truck started to light up like a Christmas tree, Stability service, trailer brake service, Locker service, Power streering service and they done turn off. Which is caused by more chafing wires that are to close to components of the engine bay getting to hot. Now my power steering turns off and when driving the truck it kicks on and make me loose control of the vehicle. Big diffect on Chevys manufacturing this vehicle. I’m not able to drive it and now they keep telling me that they don’t have the part or can’t find it.

While driving my 2018 Chevy Colorado with 42000 miles I noticed my vehicles steering would get stuck while making turns on the highway and local streets. The problem was intermittent and was getting worse. I didn't receive any warning lights or codes for this problem but realized I had to bring it to a Chevy dealer to try to resolve the issue because I was afraid to drive it any longer due to steering possibly locking up completely. The mechanic at Island Chevy in Staten Island said the electronic rack and pinion steering gear failed and I had to replace with a new one. The cost of the repair was $2700 dollars. I was very shocked by the price due to age of car, the low mileage and never doing any off road driving. I did have another mechanic look at this problem before Chevy did and couldn't pinpoint the exact issue at the time I brought it in. The mechanic told me to bring it to Chevy to hopefully pinpoint the problem and see if there were any recalls or warranties on it.

While driving, there is noticeable “shudder” that seems to feel like an issue with the transmission when it is shifting (automatic transmission). Research online shows this to be a consistent issue and concern with many owners of the 2018 Chevy Colorado. Having this shudder has not had a solution by the several mechanic shops I’ve been to. Nobody seems to know what is causing this issue, but with many owners having this same problem there must be something that Chevrolet can do to resolve this issue. We bought the vehicle brand new in 2018, and it is now paid off, but this shudder while driving has happened since we have owned the vehicle. It seems to be more prevalent while driving between 30 mph to 60 mph. The shudder happens during ever drive we take. We have the vehicle maintenance performed on all of the recommended intervals for oil, fluids, tires, brakes, etc. This is definitely something that should be a recall.

The flapper just inside the fuel filler pipe has broken loose, allowing water or dust to enter, potentially causing engine failure.

The braking system did not engaged as expected when suddenly braking in freeway commute. This resulted in a vehicle collision. I believe this issue put myself and others in danger. There were no warning lamps.

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
