2024 Chevrolet Colorado Problems

The turn signal has an intermittent condition. When I put the right turn signal indicator on to signal a right turn, after the turn is completed and the turn signal stick returns to the off position my left turn signal with signal a left turn flashing approximately 2-3 times before turning off. I took it to the local Chevrolet dealer maintenance shop and they told me the replaced the turn signal stick, however a few days later the same problem occurred again. I have also learned online that other owners have had the same issue with their Colorado pickup trucks also.

The turn signal system intermittently malfunctions. When using the turn signal, the auto-cancel function sometimes activates the opposite signal, and at times the stalk does not stay engaged when attempting to signal. This creates a safety risk because surrounding drivers may receive the wrong turning/lane-change indication or no indication at all. The issue has occurred intermittently while driving and has been presented to Cox Chevrolet in Bradenton, Florida multiple times. Cox Chevrolet has verified turn-signal over-cancel and performed prior repairs/programming. However, the issue has not been entirely resolved and continues to occur intermittently. No crash or injury has occurred, but the condition creates a risk of collision during turns, merges, and lane changes

Vehicle intermittently lunges forward during the 2nd-to-1st downshift, even while the brakes are being applied. When this occurs, the vehicle unexpectedly accelerates or surges forward slightly, travels farther than anticipated, and feels similar to being bumped from behind. Because the condition occurs at low speeds, often in tight areas such as parking spaces, stop-and-go traffic, or before a crosswalk, it creates a risk of collision with pedestrians, vehicles, or objects. The issue has been reported to Cox Chevrolet in Bradenton, Florida multiple times, but continues to happen.

Mid December 2025 my forward collision warning, adaptive cruise control, automatic emergency braking and auto high beams all stopped working. I combined the repair request with my next oil change Dec 22, 2025. The Chevy dealer, Serra, advised me that Chevrolet had no way to correct these problems, one of which was a $950 option. I have returned to the dealer more times, still no fix. I have talked to Chevrolet customer service, asked for a buy back, or car to drive till repairs and was denied. Chevrolet simply says just wait till we figure out how to fix our broken truck. I feel Serra Chevrolet has done all they can and has otherwise provided me with excellent service. Since the problems include safety features and I have waited over 4 months to date, I hope your agency can expedite the repair and secure some type of compensation for me.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving on several occasions at various speeds, and the brake pedal was depressed the pedal remained floored. The contact stated that the vehicle eventually slowed down on its own and came to a complete stop. The was towed to a dealer where it was diagnosed that the master cylinder needed to be replaced. The vehicle was repaired but the failure reoccurred a little over a month later. The vehicle was towed back to the same dealer where it was diagnosed that the battery was dead and the battery needed to be replaced. The vehicle was repaired but the failure reoccurred approximately 17 days later. The vehicle was taken to the same dealer where it was diagnosed that the drivers door wire harness needed to be replaced due to an electrical issue that killed the battery. The vehicle was repaired but the failure reoccurred approximately four months later. The vehicle was towed to the same dealer where the vehicle has yet to be diagnosed as of yet. The manufacturer notified of the failure. The failure mileage was approximately 8,400.

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).

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 35k 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. You can find 1000's of examples online and if you can pull GM repair data, I'm sure you'll find 1000's more.

Truck has 36,669 miles check engine light came on and was idling loud, after being looked at my a Chevrolet dealership came back a faulty radiator hose, and coolant was leaking. Too new of truck for this kind of problem

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.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while attempting to activate the right turn signal, the left turn signal was displayed. No warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed with an overcorrection and overcancellation of the signals. The vehicle was not repaired. The manufacturer was contacted, and the failure was confirmed, but no assistance was provided. The failure mileage was approximately 8,000. The VIN was not available.

At ~20,300 miles, severe chassis and steering wheel vibration occurred during high-speed highway descents while braking. Safety risk: reduced steering control at highway speed. The vehicle was inspected by a franchised Chevrolet dealer in Lakewood, CO. The technician's written service notes document rear rotor Lateral Runout (LRO) of 0.006 inches against GM's maximum allowable specification of 0.002 inches per GM Service Bulletin 00-05-22-002 — 3x the engineering limit. The defect was confirmed in dealer documentation and is available for inspection. After I identified this discrepancy, the Service Manager claimed the technician meant 0.006 mm (metric). Photographic evidence from the dealer's own diagnostic video shows a dial indicator clearly labeled in 0.001-inch increments with the needle resting on the 6th tick mark. A metric reading of 0.0002 inches is physically impossible to display as 6 full divisions on this tool. GM Customer Assistance denied the warranty claim, classifying it as maintenance. Lateral Runout is a geometric specification, not a wear measurement. A rotor 3x out of tolerance at 20,300 miles is a material or assembly defect. No warning lamps appeared. The safety concern remains unresolved.

Sunroof exploded while driving down the highway. Glass shattered everywhere in the interior as well all over our child car seat. Fortunately I was the only person in the truck at the time. Due to the violence of the incident I had to gain control due to the sound and flying glass. Had all windows and sunroof close with the AC on. Was going approximately 65 mph. Clear sunny day. I have more photos and video if needed. Dealer has been contacted and they will replace the sunroof under warranty.
