2024 CHEVROLET COLORADO Complaints

We purchased a 2024 Chevy Colorado mid June and drove it successfully, without incident until the end of August when the vehicle had complete brake failure. My husband was driving on I-95 in morning rush hour traffic when the dashboard lit up flashing several different indicators and a message saying "Brake System Failure" and "Service ESC" He had no brakes but could slow somewhat by applying as much pressure as he could to the brake pedal. He got the car to the dealer that same morning, Grieco Cheverolet Delray. They worked on the car all day and we were called in the late afternoon to pick up. It was explained to us that GM advised their mechanics to restart the computer that controls that component and that the problem should be fixed. We were also told they were going to go ahead and order a replacement part in case "it happened again." This comment did not leave us with much confidence. Then, as we were checking out, the employee noticed there was no explanation of what had been done to the vehicle. He called the mechanic and said he refused to hand over the keys until notes were added explaining what was done to address this serious issue. So notes were made, copies were handed over, and off we went. The truck drove perfectly until exactly one week later when the dash lit up again with all kinds of alerts and lights stating, "Brake System Failure" and "Service ESC." That's right, no brakes again. We had the truck towed back to the dealer this time and we have been told they have ordered "the part" and it will probably be 3 weeks. That was one week ago and we have not heard anything yet. We have concerns over how nonchalant Cheverolet and the dealer seem to be about a brand new car having complete brake failure twice and no real explanation as to why. Can you advise? Thank you

Component/system issue: Intermittent loss of power assist to brakes after auto start-stop startup. Safety Risk: Unable to use brakes normally. Requires hard brake pedal pumping to get vehicle to stop. Reproduced by others: No. Doesn't happen every time. It has happened a total of three times (so far). Inspected by manufacturer: Yes. The first time, the dealer found low voltage DTC set. Replaced battery. Second time, dealer found low voltage DTC (P 0562) set. They contacted GM TAC who provided a file to patch the radio software. Third time, other (possibly related) electronics issues were also present which caused the vehicle to enter limp mode every time it's driven. They've replaced the ECU and the accelerator pedal, neither of which fixed that issue. They are now awaiting a wiring harness from GM to see if that is the root cause. Hopefully it also fixes the intermittent loss of power brakes after auto start-stop startup. Warning lamps/messages/other symptoms prior to failure: No symptoms prior to the failure. Upon startup caused by auto start-stop feature, the symptoms are as follows: All warning lamps illuminate and several messages display on the instrument cluster screen about loss of ESC, ABS, traction control, collision avoidance, adaptive cruise control, and others. One by one, the warning lights go out within 1 minute, except ABS. Power assist for the brakes is not available while this light is illuminated. Within approx. 2 minutes, the ABS light goes out and brakes function normally again.

Driving down the road and truck just randomly slams on brakes and says something is in front of me when it is not.

First occurrence I was traveling 55 mph down a country road at 7:30 a.m. driving into the sun and at 55 mph with a car following me My truck just instantly locked the brakes up and came to a stop. The second occurrence was at my son's school I turned the corner at a stop sign and right after I turn the corner and started accelerating the truck slammed on the brakes to an instant stop with no cars in front of me or in the other lane on coming.

I bought a 2024 Colorado Trail Boss on May 31 and after a week the truck broke down I made a stop in a T intersection, once I had a clear path I started to accelerate and in that moment the truck jerked and at the same time I heard a loud noise under the back of the car. It felt like if I had been accelerating in neutral and suddenly changed gear to drive. After that, the car continue moving but after a few seconds the truck started to lose power and going super slow I tried to accelerate but the truck did not respond. I was able to pull off the road and stop in a parking lot. after that the truck no longer moved forward or backward regardless of what gear the car was in...the car didn't move again. he truck was towed to a Chevrolet dealer, and after two weeks, the service advisor informed me that the issue was with the transmission valve body. When this happen my family was with me in the truck, Luckily, nothing serious happened and I was able to get off the road.

After completing a right turn with a right turn signal, the vehicle will sometimes signal a left turn for 3 blinks. I believe this is because the turn signal stalk 'bounces' down to the left turn signal area when returning back to normal position from a right turn.? ? This is a safety issue because the vehicle is signaling a left turn when no turn is intended. This could cause confusion to other drivers on the road.?

I'm having an issue with my 2024 Colorado Trail Boss. After making a right hand turn with the signal on, once the stalk bounces back, it overcorrects and 'taps' the indicator and flashes left 3 times. I've seen some other owners having this issue on online forums throughout the Colorado and GMC canyon lineup. I think it's a pretty big safety concern to give improper navigation signals, 50% of the time I take a right hand turn.

Right turn signal when returning to the off position after completing a R/H turn is turning on the Left signal momentary 3 flashes. This condition happens with every use of the R/H turn signal

These features no longer work in the vehicle. There may be others that I have not noticed yet. Chevrolet requires you to purchase a Onstar subscription at the price of 25.99 a month for these safety features to work. It also requires Onstar for the talk button on steering wheel to work along with talk to text. No longer shows the current posted speed limit on road on dash. No longer shows map on dash cluster. These are what I have noticed so far.

Occasional lag in camera systems turning on. When trying to maneuver in close quarters will turn on front and 360 cameras and sometimes have to push the camera button multiple times and up to 4 seconds delay in cameras coming on
