Recalls on the 2023 Chevrolet Blazer
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

POWER TRAIN:AUTOMATIC TRANSMISSION
General Motors, LLC (GM) is recalling certain 2023 Cadillac XT6, GMC Acadia, Chevrolet Blazer, Traverse, and 2022-2023 Cadillac XT5 vehicles. The transmission may have been built with an incorrect sun gear, which can result in the driver-side half-shaft disengaging from the transmission.
Risk: A half-shaft disengaging from the transmission can result in a loss of drive power or vehicle rollaway when the vehicle is placed in park. Either of these scenarios can increase the risk of a crash.

POWER TRAIN:DRIVELINE:DRIVESHAFT
General Motors, LLC (GM) is recalling certain 2023 Chevrolet Blazer and Traverse vehicles. The left-side half-shaft assemblies may be missing a retaining ring.
Risk: A missing retaining ring on the half-shaft can cause half-shaft inner joint separation, resulting in a loss of drive power or vehicle rollaway when the vehicle is placed in park. Either of these scenarios can increase the risk of a crash.

Powertrain
Issue: On certain vehicles, a problem inside the transmission could cause the left-front axle shaft to separate from the transmission. If this happens, there would be a loss of power to the wheels. This could also cause the vehicle to roll away while parked, if the parking brake isn't used. Note: This problem could cause a grinding or clicking noise from the front of the vehicle. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Additionally, a parked vehicle that moves unintentionally could create a risk of a crash or an injury. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to replace the transmission sun gear.

FORWARD COLLISION AVOIDANCE: WARNINGS
I am reporting a recurring safety issue with the Forward Collision Alert/Automatic Emergency Braking system on my 2023 Chevrolet Blazer 2LT. The vehicle frequently activates the Forward Collision Alert when there is no vehicle, pedestrian, or other obstruction in front of me. The red collision warning will illuminate and the system will beep even when the roadway is clear. More concerning, on three separate occasions the vehicle has unexpectedly applied the brakes extremely hard while I was driving in traffic despite there being no obstacle or imminent collision. The most recent incident occurred on August 11, 2026. I was making a turn through a busy intersection when the Automatic Emergency Braking system suddenly activated and applied the brakes extremely hard. There was no vehicle, pedestrian, or obstruction in my path that would have required emergency braking. The sudden braking occurred while I was in the intersection and created a serious risk of being struck by surrounding traffic. The braking force was severe enough that my seat belt restrained me very hard and caused an injury to my chest and flew me forward into the steering wheel while also risking the vehicle behind me to almost slam into me. This was not an isolated occurrence. This is the third time the vehicle has unexpectedly applied the brakes hard while I was driving in traffic. In addition to these three braking incidents, I have experienced frequent false Forward Collision Alerts where the red warning and audible alert activate when nothing is in front of the vehicle. I am concerned that the Forward Collision Alert/Automatic Emergency Braking system is malfunctioning and could cause a collision by unexpectedly stopping the vehicle in moving traffic. I am requesting that this recurring safety issue be documented and investigated.

ENGINE
The vehicle’s radiator developed a coolant leak that was discovered and confirmed by the dealership during a routine oil change, tire rotation and state inspection. There were no warning lights, warning messages prior to the dealership discovering the leak. The radiator required replacement. The dealership also told me that they had the replacement radiator on hand because this type of radiator failure had been occurring fairly often with this type of vehicle. The radiator failure presented a potential safety concern because a coolant leak can worsen without warning and result in a sudden loss of coolant, engine overheating, or vehicle breakdown while driving. Because there were no warning lamps or other symptoms before the leak was discovered, we may not have had any indication that the cooling system was failing. The problem was confirmed by the dealership during inspection, and the dealership determined that the radiator was leaking and needed to be replaced. The vehicle/component was inspected by the dealership. No manufacturer, police, or insurance inspection has occurred, to my knowledge. There were no warning lamps, messages, overheating, or other noticeable symptoms prior to the dealership finding the leak. The vehicle is only three years old, with 39000 miles on it at the time of the failure. I am reporting this because a radiator failure at such a young vehicle age, particularly one that develops without any warning to the driver, could potentially create a safety hazard if the coolant loss becomes severe while the vehicle is being operated. I’ve seen many complaints in online forums that this is an ongoing issue with these radiators used by Chevy. It seems the replacement radiators are having the same issues. Why can’t something be done? Dealership information: #1 Cochran Chevrolet Cranberry [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

"I am the owner of a 2023 Chevrolet Blazer RS. The digital odometer and speedometer screen intermittently crashes and goes completely black for 15 to 20 seconds while the vehicle is in motion on public roads. This creates an immediate safety hazard as I am left with zero knowledge of my current speed. General Motors has acknowledged this specific software stability bug under Technical Service Bulletin 22-NA-023 but refuses to fix the issue due to the vehicle being 9 days past its 3-year calendar warranty, despite having only 32,400 miles." I contacted your GM agent @ 800-222-1020 and was told its out of warranty sorry, that is horrible service espeacially for a safety issue and a 55,000 vechicle that only has 32,400 miles

Re: Vehicle Safety Defect Complaint – 2023 Chevrolet Blazer To Whom It May Concern, I am submitting a formal safety defect complaint regarding my 2023 Chevrolet Blazer. This vehicle has exhibited multiple system failures that present a serious risk to driver safety and public roadway safety. The vehicle was purchased new on July 20, 2023. Beginning on April 21, 2025, at approximately 27,610 miles, the vehicle developed a progressive defect initially presenting as oil-related issues. Despite multiple repair attempts, the condition worsened and required a full engine replacement in January 2026. Following the engine replacement, the vehicle continued to experience critical safety failures, including engine stalling, reduced engine power warnings, and electronic stability control (ESC) alerts. On April 26, 2026, the vehicle experienced a driver assistance system malfunction in which it attempted to steer off the roadway. I was forced to manually disable the system to maintain control of the vehicle. On April 27, 2026, the vehicle exhibited a fuel system failure, including fuel leakage and fuel odor, along with multiple simultaneous warning indicators: • Reduced Engine Power • Service ESC • Steering Assist Reduced / Drive with Care • Power assist driver system disabled This combination of failures presents both a fire hazard and a loss-of-control risk. Additionally, I was informed by the dealership that a high-pressure fuel line, a one-time-use component, was not replaced during the engine installation. This raises concerns regarding improper repair and continued unsafe operation of the vehicle. The vehicle has undergone multiple repair attempts and a major powertrain replacement, yet continues to present serious safety concerns. Due to these ongoing issues, I do not feel safe operating this vehicle. I respectfully request that NHTSA review this matter for potential safety defects that may impact other vehicles of the same make and model.

Since I’ve got the vehicle i experienced issues with it not going in drive or reverse sporadically. I was air to obtain this in video and show it to the dealer for the first time Dec 2023. In addition and overtime it’s seems this issue may go hand and hand with the lane assist issue that had been known on Chevy models where they either don’t work of they don’t recognize the lanes correctly and they pull although your in the correct lane.i have specifically taken the car in on 3 or more occasions about it disengaging and not driving forward or backwards. More recently it started to seem as if while u was actually driving the car did not want to accelerate forward and then while trying to accelerate the steering wheel pulled and caused the car to spin out of control on the freeway. The car was just in the shop from End of April till May and the issues are unable to be duplicated so I just keep getting pushed off with the car. The car radio constantly malfunctions and glitches i several different forms, black screen no sound or not allow Bluetooth capabilities. My most main concern is this power train issue and me getting stuck with a car that is going to be it of warranty and the issue has never been resolved even though I have showed the dealership a live video of the occurring issue that there is something wrong here.

More recently it started to seem as if while u was actually driving the car did not want to accelerate forward and then while trying to accelerate the steering wheel pulled and caused the car to spin out of control on the freeway. The car was just in the shop from End of April till May and the issues are unable to be duplicated so I just keep getting pushed off with the car. The car radio constantly malfunctions and glitches i several different forms, black screen no sound or not allow Bluetooth capabilities. My most main concern is this power train issue and me getting stuck with a car that is going to be it of warranty and the issue has never been resolved even though I have showed the dealership a live video of the occurring issue that there is something wrong here.
