2024 Chevrolet Colorado: check engine light

Filed Oct 28, 2026 · Fuel system · 22,000 miles · TX

The contact owns a 2024 Chevrolet Colorado. After starting the vehicle, the engine ran for several seconds before the vehicle unexpectedly shut off. The check engine warning light illuminated, and the word "Key Fob" was displayed while the key fob was in the contact's hand. The vehicle failed to restart and made a clicking sound. An independent mechanic diagnosed the vehicle with fuel pump module failure. The fuel pump module was removed and cleaned; however, the failure reoccurred four months later. The contact purchased a new fuel pump module and the mechanic installed the part. The manufacturer was notified of the failure by phone. The failure mileage was approximately 22,000.

I bought this vehicle late June 2026 and it is currently September 1 2026 and last week I encountered a check engine light. Its already having coolant issues. Way too early for something like this. Only 64,000 miles.

Check engine light came on and the dealership said it was because the coolant was low due to the radiator hose leaking. I was told by the actual mechanic that they’ve had to do a lot of radiator hoses and that it is a known defect with the Colorados and the traverses but that GM hasn’t done a recall on them yet. That is what brings me here. My truck is only 2 years old and this shouldn’t be happening right now. Thank you for taking the time to review this and I hope GM addresses the matter promptly.

The vehicle is registered to me; my mother was the driver at the time of the failure. At ~2,963 miles, the truck developed intermittent check engine and ABS warning lights. The dealer pulled DTC C058A (brake system control module) and P25A2. Per GM bulletin PIT6012A, the battery was replaced and a brake plunger motor sensor learn was performed. The same codes returned within weeks. The dealer then diagnosed internal failure of the brake master cylinder and reservoir, documented the vehicle as "unsafe to drive," and replaced both under warranty. The truck sat at the dealer over six weeks due to a nationwide parts backorder. Repairs were completed April 4, 2025. On May 2, 2025, at ~6,500 miles, the driver was traveling downhill on a city street in the rain at roughly 20 mph. The brake pedal suddenly became hard and resistant. Despite full-force pedal pressure, the vehicle could not be stopped. It entered an intersection, struck another vehicle, then struck a tree. Front and side airbags deployed; the vehicle was totaled. The driver sustained a concussion, broken finger, and severe back and knee injuries, was transported by ambulance, and required months of concussion treatment including vestibular therapy. The hard, resistant pedal is consistent with failure of the electronic brake boost assist (eBoost) system, leaving only unassisted hydraulic braking (roughly 4–5x normal pedal force). This matches other owner reports and the class action in Barron et al. v. GM LLC, which cites defective master cylinders with a missing internal cartridge seal on the same platform. The vehicle is no longer available for inspection. The driver was concussed with significant short-term memory loss at the scene; statements in the police report may not reflect the mechanical failure. Full police report available on request (exceeds 10 MB limit).

Check engine light with codes p0700 and p2796 has been happening for months with multiple failed repair attempts. Vehicle was returned to me by the dealer supposedly fixed. I drove it 15 minutes to the high school for an art fair my daughter was in. They (my family) rode with me home. Check engine light was on again. On the way home, the transmission was acting strange, not shifting properly. About half way home, it got stuck in a gear at 3500 or so rpms and would not shift. I tried the manual shifter, and it didn’t work. Stuck in gear. Concern was that we were approaching a hill when it did this, and I could not get the vehicle to shift to deliver the appropriate level of power I needed to ascend the hill. It thankfully did eventually shift, but it was scary for a few seconds, especially since I had my wife and all three of my kids in the vehicle. I dropped the vehicle off the next morning. It got stuck in gear at 3500 RPMS again on the way to the dealership. Two dealerships have made multiple failed attempts to fix the transmission issues. Several attempts to contact GM have gone without a response. No one in my family feels safe in the vehicle after what happened.

I have a 2024 Chevy Colorado Trail Boss that needs an Upper Radiator Coolant Hose. But apparently this is on nationwide backorder because although there is not a recall GM put a bulletin out they are aware of the issue that appears to be a degraded seal inside hose fitting so the whole hose needs replacing. I live in [XXX] and it is not available here and I have called OH, [XXX] , [XXX] and other state dealerships and Noone will sell that part because of the backorder. My truck has 40k miles. And every dealer I called this is a huge issue with these trucks. So it is not a wear issue when it is on nationwide backorder and it'll take 1-2 weeks +/- to get. My warranty won't cover as they say it is a wear part and no recall. So how can there be no recall on a nationwide issue with these trucks. My truck cant be driven right now due to check engine light, low coolant, leaking hose, fan blowing high, no heat and this is all related to this backordered part. Someone told me to report this issue so that is what I am doing now. Again this should be an active recall.

Check engine light appeared and fans kicked on loudly. Stayed on even after shutting the vehicle off. Vehicle is a 2024 with only 28,639 miles on it. Upper radiator hose was leaking and would not seal. Took to dealership for repair and replacement. Was informed it was the 3rd Chevy Colorado this week with this issue! Was stunned. Further internet research found a staggering number of forum posts with this same issue. This is a recall-worthy issue at this point. Please consider issuing a recall based on the safety issues this may pose if engines seize or overheat as well as the sheer number of the same reported incidents.

A leak in the upper radiator coolant intake hose has been found. This leak is the result of a bad rubber o-ring in the connection between the radiator and the hose. This has resulted in coolant regularly leaking from the vehicle causing power train issues, health and safety concerns where toxic coolant is leaking and environmental concerns. A loud “whooshing” noise was heard from the engine bay prior to eventually a check engine light being illuminated when the coolant level became low enough.

ABS check engine light came on after initially taking the vehicle in because of the brakes feeling weird and making noise. This similar issue has been experience by multiple users reported on a Chevy Colorado group page on facebook to include 2 cases of individuals, one with a Colorado and another with a GNC Canyon, both GM vehicles, that had their brakes fail while operating the vehicles. This was a concerning issue because, in my case, while I drove the vehicle, I was able to punch the brake pedal all the way to the floor while the vehicle was slowing down. The vehicle and part were inspected about 3 different times with the final time, and with video proof of an odd noise it was making, which then caused the dealership service department to actually check the brake pump which then they found to be faulty and needed replacing. This also took about a month and a half of wait time because the part was on backorder. I also spoke to Chevrolet directly where they did not seem to be aware nor cared at the fact I explained to them many owners experienced this same issue and did not acknowledge my concern for safety of the vehicle itself.
