2018 Chevrolet Colorado owner complaints (15)

• STEERING

  Power steering failure, without incident. It started one morning, after turning off truck the previous day. Warning lights displayed as soon as truck was started. Very difficult to turn steering wheel. Too dangerous to drive. Dealer indicated the steering rack should be replaced.

• POWER TRAIN,UNKNOWN OR OTHER,ENGINE

  Engine fails it violenty thumps and studders and drops from highway speed with no warning. This is a mfg. defect and also an EXTREME SAFETY CONCERN. The engine studders and thumps and we were almost rear ended by a truck when our truck could not go into gear properly. It is very scary! Dealership confirmed that they have many vehicles with same issue and recommended a Super Flush of transmission but not sure this will correct problem or cause more problems. There is no warning when these incidents occur and the driver has no control to avoid it. It is commonly referred to as the Chevy thump and studder and a known mfg defect in which GM refuses to pay for repairs causing consumers an extreme hardship! This is an ongoing issue affecting thousands of vehicles and someone is going to die! There is no negligence of operator of vehicle, it is a manufacturing defect that affects thousands of GM vehicles and they are doing NOTHING about it except expecting customers to keep incurring cost to try to remedy a repair at our own expense which is unfair! The government needs to force a recall at GM's expense!

• POWER TRAIN

  Luggage and shudders at cruise speed, seems like auto transmission is coming apart. Paid $500 for the trans flush the service bulletin suggests but didn’t help, shop quoted a $8000 replacement on a vehicle with 60k miles. This should be a recall

• FUEL/PROPULSION SYSTEM

  7.5 amp to fuel injectors has blown 2 times unknow reason causing loss of power 1st time on country road then 2nd time on a highway it's a common problem from the Chevy Colorado forums regarding the 2.8l lwn engine

• POWER TRAIN

  Highlighting a materials defect with the rear crankshaft reluctor ring on the 2.8 LWN Duramax, installed in the Army Infantry Squad Vehicle and the 2015-2023 Chevrolet Colorado, from which it is based. When the ring delaminates, due to age, the vehicle engine shuts off and no start, rendered dead lined, as the ECU can no longer "see" the crank position. Requiring the transmission to be removed to rectify the issue.  I was pulling a trailer up a hill on the freeway when my truck down shifted, in an effort to slow down for a bus that was merging unexpectedly and the truck died at speed. The increase in RPM initiated an unplanned, instant disassembly of the ring due to cracking on the material and increased centrifugal force, shutting off the engine without warning, at speed. Again, just dead stick to the shoulder, towing a trailer, on the freeway. That could have been bad... Had truck towed to GM dealer, for a month-long repair.

• POWER TRAIN

  transmission is not shfting properly.Truck losses speed and shutters when trying to accelerate.Difficulty climbing hills.Especially dangerous when merging with traffic.Only 33,000 miles on my truck.GM should recall to address this much complained about issue.

• ELECTRICAL SYSTEM,AIR BAGS,FUEL/PROPULSION SYSTEM

  All the sensors seem to not be functioning correctly. Doesn't tell me the right measurements for the wheels, gas, over heating. Right front passenger door locks/unlocks when it wants. It chokes up when trying to accelerate. Theres a rattling noise that comes from under the car. First time I took it to the dealership, they stated it was a bolt that had come loose on the exhaust pipe. They placed a new one which lasted a year and a half and now its back to making the noise. I took it again to the dealership, this time they claimed they couldn't find anything. My airbag sensor keeps coming on constantly. My fuel sensor claims 116 miles one moments and 5 or 6 minutes later, it says I have 50 miles. My car was over heating and low on Anti-freeze, the car never notified it was over heating.

• POWER TRAIN

  Transmission oil leak with only 60,000 miles just bought from a dealership as is 3 days ago and was not informed of the issue

• UNKNOWN OR OTHER

  Saturday July 12, 2025: My truck got an ACTION Required notice: "Exhaust fluid Quality Poor See Owners Manual NOW 100 miles until 65MPH Max speed" I turned around and returned home to get a different vehicle to do what i needed to do. Monday, July 14 My mechanic hooked it up to the vehicle scanner and got the code information: "P11D5: NOx Sensor 2 Exceeded Minimum Learning limit (Symptom 00) - Current DTC, Test failed since DTC Clear, History DTC, Test not passed since power up, warning indicator requested" So we ordered and replaced the Sensor, still the action required message remains... I am now down to "64 miles to 55mph Max Speed" and my dealership is telling me there is nothing more that can be done, unless i want to pay up to 5k for additional repairs that in their experience may NOT fix the issue?? I've googled the issue and MANY MANY people complain of this issue and there appears to be no actual fix for it.... GM tells me that im out of luck and they have no information regarding a fix or remedy for the situation!

• UNKNOWN OR OTHER,ENGINE

  The problem started two months ago, with a loss of engine power and a stability track warning on the dashboard. This happened occasionally while driving, often going away on its own by turning off the vehicle. Two weeks ago, I took it to Chevrolet for an inspection. They did a general inspection and said it was a factory defect. Now, the vehicle has the problem constantly, and there are times when it's undriveable. That's a risk for me.

• POWER TRAIN

  Clunking sound coming from rear end upon normal acceleration. When I take my foot off of the brake pedal, and depress the gas pedal, A loud clunk appears to come from the differential. If I coast first and then depress the gas pedal, it is not as pronounced. When you slow down to make a corner, and resume speed exiting the corner it is also pronounced. It should be noted that I am a safe adult driver (safe driver module installed in truck) and have 35,800 miles. My truck has always been serviced by my Chevrolet dealership; I am an older gentlemen and never drive recklessly. I'd like to think the rear differential should not be making a clunking sound at this point in its history

• ENGINE

  The issue is with the transmission not shifting as should. The issue is called Shuddering and seems to be a know isuue. If you google search issues with 2018 Chevy Colorado this is the first issue that comes up. This could cause an accident. If gears aren’t shifting properly and I cannot excel as needed I could be rear ended or cause me not to be able merge into traffic if once accelerating it shudders and causes my speed to slow. I think there should be a recall for this issue.
