I am not comfortable with this car, I took this car to the dealership to get fixed and checked on recalls but they could not fix the most important and most dangerous recall. They worked on recall#N252492430 and recall #N242468490 from [XXX] # [XXX] . When I got there, no one gave me an update of the car they only gave me a receipt with 3 pieces of paper and that is it. What can i do in this case? I can not drive this car knowing the brakes will go out and I might have an accident and crash.

I am writing to report a serious safety concern regarding the adaptive cruise control and rear cross-traffic alert systems in my Chevrolet Blazer. These systems are malfunctioning in unpredictable and potentially dangerous ways. On multiple occasions while driving on the expressway, the adaptive cruise control has abruptly and forcefully applied the brakes without any apparent reason. There have been no vehicles directly in front of me posing an immediate threat. While there may be traffic in adjacent lanes, my lane has been clear. This sudden deceleration is alarming and dangerous, creating a significant risk of rear-end collisions from vehicles following too closely. The red lights will come on and indicate an imminent problem but it is a malfunction. The abrupt stops are frightening for all passengers, and the frequency of this occurrence is troubling though on rare occasions since I have first owned the car. I have observed similar complaints from other Blazer owners on online forums, reinforcing my concern that this is not an isolated incident. The dealer has not being able to reproduce but acknowledges that other drivers have a similar issue. Further compounding this issue is the malfunctioning rear cross-traffic alert system. While backing up at low speeds, the system will unexpectedly and forcefully engage the brakes, even when there are no vehicles present in the surrounding area. While less dangerous than the expressway issue, this erratic behavior still indicates a significant system flaw. I understand that adaptive cruise control and rear cross-traffic alert are intended as safety features, but their current malfunctioning poses a substantial safety risk. I urge you to investigate this matter thoroughly. I expect these features to function correctly and reliably. I request immediate action to address these defects and ensure the safety of myself and other drivers.

The vehicle will automatically extremely hard brake while moving for no apparent reason, with no obstructions present. This problem startles driver and passenger and can present a danger to vehicle of being hit by other vehicles not expecting a hard braking situation for no apparent reason. Please investigate and make manufacturer responsible to fix the issue. Thank You
When the Automatic Emergency Braking system is enabled, it will suddenly brake when in reverse even though there is no obstacle at the back. The braking is so sudden that it is painful. I reported it to the dealership but they never got back to me about a solution. I have disabled the AEB for now.

1EA26006 · Electronic Brake Module Component Failure
Opened Aug 21, 2026 · No close date supplied
Status: open (inferred from source dates) · Service Brakes
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.
