2024 Chevrolet Colorado Problems

Love my 2024 Chevy Colorado and researched every aspect about it prior to purchase....accept the REQUIRED Onstar subscription to enable the handsfree "speaker button" @ RH side of steering wheel for phone, navigation, etc. I was finally made aware of a promotional that came w/ the truck by an Onstar rep that only worked for one month, which no one @ the dealer, sales rep, finance, etc told me about. Once function quits, using an Android phone, it is impossible to utilize, requiring physically handling the phone to initiate and end calls.....which is unsafe and illegal in my state. It is aggravating to me that one should have to pay 45.00 a month for a great feature that is factory installed on the steering wheel when my 2015 Ford worked for free for the entire time I owned it. As a safety item it should be free and could lead to issues for others if they opt out...distraction BAD

While driving home multiple lights,messages and sounds came on the dashboard. I stepped on the brake and there were no brakes. I put vehicle in neutral and pumped brakes a few times. I was not traveling that fast so the vehicle stopped before I hit the person in front of me. I drove 10 mpg with my hazards on to the nearest gas station. I called Chevy service and they sent a tow truck N/C to bring to the dealer.

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.

Was on a trip and on the highway home the service break lights came on. By the time we got home(less than 200 miles) the breaks where scraping the calipers. Truck only had 25,586 miles on it when they picked it up to take to the shop. Dealership had to replace the break pads, calipers and rotor on the front driver side.

Engine cooling system has a known leak. It is rather expensive out of pocket and although there is now a tsb the tsb does not cover the danger of overheating an engine and being stranded on the side of the road. Also the coolant leaking causes an unseen hazard by polluting water supplies with one of the more known toxins to the water and environment.

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.

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 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

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.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while attempting to add windshield washer fluid to the windshield washer fluid reservoir. The contact stated that the washer fluid failed to pass through the filler neck and enter the reservoir. The vehicle was taken to the dealer, who informed the contact that the failure was due to a poor design flaw and that there was no repair available currently. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 14,000.

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.
