2024 Chevrolet Colorado Engine Problems

Owner reports

Selected complaints filed with NHTSA by 2024 Chevrolet Colorado owners, lightly cleaned up (personal details are redacted by NHTSA).

Copied this from a forum and it's the same thing for me. I'm editing to fit my unique situation. This is an $800 repair at my dealer for a $40 part! 5 day backorder so I'm without a vehicle. The upper radiator hose on some huge percentage of these trucks fail (mine has failed at 37500 miles). You can check the Colorado Chevy forum, youtube, etc., et al, and find plenty of instances where this has failed. As this is the cooling system, it can cause the engine to overheat and potentially ruin the engine. The flaw seems to be an engineering issue with the rubber seal they use (instead of a high quality o-ring) to seal the upper hose to the radiator. Additionally, since this can cause engine failure it should be addressed immediately. …

The truck has 28,000 miles and has been only driven for commuting on interstate conditions. While traveling on an 80 mile commute, I experienced complete engine failure while traveling at 75 MPH (the posted speed limit is 80). As the engine failed, I was placed in a dangerous position as there is no pull-off and traffic was heavy. I was stranded in winter conditions with no ability to heat or stay warm. OnStar assisted with a tow to the closest dealership which was Ressler Chevy in Bozeman, MT. The results of the inspection indicated a failed crank shaft, hole from internal debris in the engine block, and the engine seized. This has resulted in a engine replacement. When asked, this has been an ongoing problem with the 2.7 engine yet there is no recall and the fix is to replace it with another 2.7 with no fix to the issues. …

The vehicle was purchased new from Courtesy Chevrolet in San Diego, CA. After 500 miles on the odometer, I decided to change the oil with fresh Castrol Syntec 5W-30 which has the Dexos 1 Gen3 approval along with a new ACDelco PF66 oil filter. Upon removing the oil drain plug and after all of the oil had been drained, I noticed the threads for the oil drain plug appear to be loose and perhaps broken free from the stamped aluminum oil pan. Luckily, I was fortunate to obtain a perfect seal while pulling on the drain plug and threading it into the pan. The attached images are from a new oil pan I purchased. The steel threaded insert inside the stamped aluminum oil pan has broken free and the only way to properly repair it is to have the factory oil pan replaced with another. …

Date: [redacted] | Location [redacted] Leaving Costco 1 after entering entrance headed to Savannah. I was traveling at approximately 60 miles a hour with heavy traffic alongside me and a tractor trailer behind me when I felt my Truck quickly de-accelerate on its on. Then I saw the "Sudden Warning on Dashboard, "Reduced Acceleration - Drive with Care" then the 2nd Warning on Dashboard, " Service Traction Control." I was almost REAR ENDED by the Tractor Trailer. I was never so startled but I keep my nerve....got over to the right lane at slowed speed (It was weird. Speed slowed but felt like I was in high gear....) I droves about a mile .... got off at next exit and pulled over at gas station. I turned car completely off and tried to reset computers, but it would not. I decided to drive under 35 miles a hour on side streets to Dan Vaden dealership.

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 20K miles). You can check the Colorado Chevy forum, youtube, etc., et al, and find plenty of instances where this has failed. As this is the cooling system, it can cause the engine to overheat and potentially ruin the engine. The flaw seems to be an engineering issue with the rubber seal they use (instead of a high quality o-ring) to seal the upper hose to the radiator. Additionally, since this can cause engine failure it should be addressed immediately. Instead, my local Chevy dealer, since its not a recall item, said they could schedule a time next week for me to LEAVE the truck and then they would get to it in 7-10 days. This is extremely unfair to the consumer who depends on these vehicles. This should absolutely be a recall item. …

I was driving the vehicle up a mountain, in a 70m speed zone, when the dash board lit up. The vehicle started to decelerate, I pushed the gas petal but it just decelerated. I put on the emergency light and continued to the exit. Stopping in Liberty Pa, at an Exxon station. Called GM roadside assistance. On-Demand Diagnostics stated: ECM-Engine System code P00700. TCM P0658, TCM P2729, and P281D. Odometer reading 3840. Remaining oil life: 49%. Our safety was compromised by the unexpected deceleration of the vehicle and possibly being stranded on the road. Was luck to get off the highway safely. The car was towed to Jack McNerney Chevrolet, Inc. 363 NYS Rt13, Tully, NY 13159 +13156968976. The car has been at the dealer since the night of [redacted]. Have been told that the car is not drivable.

I was told that my vehicle has a bent exhaust valve, which has caused irreparable damage to the engine and requires a complete engine replacement. The dealership could not determine what caused the valve to bend, but they indicated that it could potentially be a manufacturing defect, although they could not confirm that. My vehicle has now been at the Chevy dealership for more than 30 days, and I was informed that there are currently no replacement engines available from the factory due to a shortage. Given that this appears to be a known parts shortage, I assume other owners of the same make and model may be experiencing similar issues, although I cannot confirm that. The vehicle has approximately 10,000 miles on it.

Immediately after braking in traffic or at a complete stop the there is hesitation with the accelerator. If I have to brake in traffic on the highway and then need to accelerate to enter another lane the vehicle will not accelerate for several seconds making it dangerous if the traffic in the other lane is traveling at a higher speed. At a stop sign when looking both ways to make sure the road is clear if I need to accelerate quickly the car will not move for several seconds no matter how far I push the accelerator. This almost led to a crash at a limited visibility intersection. I have not taken it to the dealer yet, but that is the next step.
