FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES
I am reporting a potential safety defect involving unintended automatic emergency braking/forward collision warning/brake-control behavior, reverse automatic braking, parking brake behavior, and driver-assistance/sensor calibration. Incident XXX ~11:15 AM, [XXX] driving 2024 Chevrolet Blazer EV ~20–25 mph on/near [XXX]. Vehicle displayed red collision alert and abruptly braked hard although the lane was clear; only a car was parked in a driveway on the right. Sudden braking created serious risk of rear-end collision/loss of control. Vehicle used for family transportation; toddler (~30.8 lb) had been in vehicle ~10 minutes before and family includes blind/visually impaired passenger. History of unwanted reverse emergency braking ~every 45 days: Jan 2026 near Crust Pizza Woodforest (backing up) and March 2026 at H-E-B 7988 FM 1488 Magnolia (backing out), jolting child in rear-facing car seat. Prior service at Keating Chevrolet Nov 12, 2025 (including recall/service for Unintended Parking Brake Engagement N252503010 and missing chassis harness plugs update) did not resolve unwanted braking. After June 10, AEB/front pedestrian braking/intersection collision braking were disabled as temporary safety mitigation. Vehicle removed from daily family use, available for inspection, and I request NHTSA review. Any inspection should preserve relevant braking/parking/AEB/forward collision/sensor data before any reset/update/repair.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving in a plaza parking lot at approximately 18mph the AEB engaged for no reason. There were not any objects near our car to activate the system. The AEB activated so quickly and abruptly that my spouse and I needed to seek medical attention due to whiplash.

ELECTRICAL SYSTEM
Driver Information Centre (DIC) and Infotainment go dark. This has happened twice now over the last 2 months. While driving suddenly the infotainment goes blank and loses the radio and then the DIC follows by going blank (dark). So I was left with no speed indication. The car drives normally during that time. After 30 seconds to a minute the screens come back on as if it rebooted while driving.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
The front camera lens cover — located in the grille below the Chevy bowtie logo — has developed a spiderwebbed/shattered crack pattern. There is no impact damage to the surrounding grille or bodywork. The vehicle was garaged and not in use when the damage was discovered. The camera appears to still be working and parts of the image are crystal clear but the cracks in the cover distort the picture and make it impossible to use reliably. This is consistent with a material defect, not road damage. I have opened a case with GM Customer Care regarding this defect. My case number is: XXX.

There is a defect in the motorized electric charge port door. When you press the button it rarely works to open the charge port door leaving me with unable to charge my vehicle. I fear this will leave me stranded and my only course of action will be to rip the door off in anger. Many others are experiencing this issue. Chevy needs to address this.

AIR BAGS, STRUCTURE:BODY, SERVICE BRAKES
On 10/29/25 I brought the vehicle in to Richard Lucas Chevrolet due to the alert from my insurance co that there was a recall with parking brake system. The dealership checked the car and told me they had to order the part that was needed due to the recall. Prior I also made the dealer aware that the car had recently stalled on me in the middle of the street, I was told by the dealership that this was apart of the recall! The dealership allowed me to drive the car and stated to me that they would call me when the part comes in! 2 days later on 11/1/25 while driving the car lost control, the brakes wouldn't stop and I crashed into 2 parked cars and landed on top of the second parked car which was a pickup truck! All of the airbags deployed and my body is pretty messed up from this horrific crash and this has caused fear in me of driving!

EXTERIOR LIGHTING, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
This vehicle experiences multiple recurring safety-critical system failures while driving, creating a dangerous operating condition for both the driver and the public. 1. Dashboard / Instrument Cluster Failure While Driving While the vehicle is in motion, the dashboard display intermittently shuts off completely. When this occurs, I cannot see my speed, warning lights, battery status, or any other gauges. This creates a severe safety risk because I am effectively driving without any instrument information. The issue occurs while actively operating the vehicle on public roads. 2. Navigation / GPS Location Failure The vehicle’s built-in mapping system frequently shows my location several states away from my actual position. Even though the location is incorrect, the system continues to provide turn-by-turn navigation instructions based on the incorrect location. If these directions were followed, it could cause a driver to make unsafe maneuvers or become distracted while attempting to correct the navigation error. 3. False Automatic Emergency Braking Activation The automatic braking system frequently activates even when there are no vehicles, pedestrians, or obstacles present. The vehicle abruptly slows or brakes on open roads with nothing nearby. This creates a significant safety hazard because it could cause a rear-end collision if another vehicle is following. Repair History / Ongoing Issue: This vehicle has been taken in for repair multiple times for these issues. Despite attempted repairs, the problems continue to occur. The recurring nature of these failures indicates a systemic defect that has not been corrected. Safety Concern: These failures create multiple hazardous driving conditions: Loss of dashboard information while driving Incorrect navigation location and directions Unintended automatic braking events Allowing this vehicle to remain in service with these unresolved defects places both the driver and the public at risk.

FUEL/PROPULSION SYSTEM
I recently purchased this EV Blazer and one day I went to charge it at a fast charging station. It would not charge and so I got it to the Chevy dealership in Yakima, WA. They told me that the battery itself had been physically damaged due to the location of the battery and it not being protected. I have no recollection of ever hitting anything and there was no visible or damage to any other part of the Blazer. It seem to me that the location of the battery and it being unprotected is a major design flaw.

The keyless entry and start system intermittently fails to detect the key fob, preventing the vehicle from starting, locking, or unlocking. On one occasion, a "Service Keyless Start System" warning appeared on the dashboard while the vehicle was being driven at 75 MPH on a highway. The driver was unable to safely stop and feared the vehicle would become inoperable in traffic if turned off. The issue first occurred on January 1, 2026. Both key fobs were tested with new batteries — both exhibited the same failure, indicating the defect is in the vehicle's key detection system, not the fobs. Roadside assistance confirmed this was an EV-specific system issue they could not resolve. The vehicle was taken to an authorized Chevrolet dealership for repair. It was in the shop for approximately 5 days. The dealership performed a full system upgrade and completed safety recalls but stated they could not replicate the key detection issue. Within approximately 30 minutes of picking up the vehicle after the first repair, the "Service Keyless Start System" warning reappeared while driving at highway speed. Two days later, the vehicle completely failed to start, lock, or unlock, displaying "No Key Found" with the battery at 100% charge. The vehicle was towed back to the same dealership for a second repair attempt. During the second escalation, the manufacturer's EV support team noted that the manufacturer's internal system showed safety recalls still appearing as open, which appeared inconsistent with the dealership's paperwork from the first visit claiming those recalls were completed. The vehicle has been serviced twice for this defect. The component — the keyless entry/start detection system is available for inspection. The intermittent nature of the failure makes it especially dangerous, as the driver cannot predict when the vehicle will become inoperable. This defect poses a serious safety risk if the vehicle loses key detection while being driven at highway speeds in traffic.

I am filing a complaint regarding my 2024 Chevrolet Blazer EV (VIN: [XXX] ) due to an unresolved defect and repeated unsuccessful repair attempts. My vehicle has been presented to the dealership on four separate occasions for the same recurring mechanical noise issue. Despite these repair attempts, the defect has not been corrected. In total, the vehicle has been out of service for approximately thirty cumulative days. After the most recent repair, the same issue has again returned. I now have video documentation of the recurring defect. Additionally, during one of the repair visits, I was provided a gas-powered rental vehicle and incurred out-of-pocket fuel expenses, despite owning an electric vehicle. General Motors has declined to offer reimbursement for these expenses. Due to repeated unsuccessful repair attempts and the amount of time the vehicle has been out of service, I have formally placed General Motors on notice under Michigan’s Lemon Law and am pursuing review for repurchase or replacement eligibility. I am requesting assistance from the Attorney General’s office in obtaining a fair resolution, including reimbursement for expenses incurred and proper resolution of the ongoing defect.

ELECTRICAL SYSTEM, ENGINE
On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Contining with issue referenced in 11701484. This morning (1/28/26) when leaving my home, I backed out of my driveway. Once I put the car into drive, the forward collision warning went off and locked up my car. The brakes would not release and I could not move out of the way of oncoming traffic. I do not know what allowed the brakes to finally release. I changed over to 4x4, put it into park and back to drive. My car finally was then allowed to move.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
I have found multiple times that the Instrument Panel (IPC) display and the center Infotainment displays have gone dark while driving. This has put me in unsafe driving situations because I am unable to monitor my speed and other important information displayed on the dashboard, or to control critical safety controls such as headlights, and other ADAS safety controls. Several software updates have been installed by the dealership, but the problem has persisted, suggesting a hardware issue with the radio unit. The manufacture insist it is a software problem and that they are working on a solution. Declining to replace the radio under warranty, additionally, they want me to wait until a new update is released, and in the meantime, my bumper-to-bumper warranty is about to expire. I have found that the radio unit is the main control module for both displays, multiple ADAS controls, and Headlights, and it should be recalled, with the manufacturer extending the warranty or including the radio as a safety feature under the extended powertrain warranty.

To Whom It May Concern, I am submitting this complaint regarding my **2024 Chevrolet Blazer** and the handling of my case by GM, GM Financial, and affiliated dealerships. In **sub-zero temperatures**, the heating system in my vehicle completely failed while I was transporting my **newborn child**, creating a serious safety concern. I immediately sought assistance at **Moran Chevrolet**, where I was denied service, told no loaner vehicles were available, and advised to continue driving the vehicle despite the dangerous conditions. Out of necessity, I drove over **30 miles** to **Al Serra Chevrolet**, where my vehicle was finally taken in. I was provided a **gas-powered loaner** and was explicitly told that fuel expenses would be covered through **GM Executive Concierge**. Unfortunately, my experience with GM Concierge has been unacceptable. I was assigned a representative but have **never spoken to her live**, despite numerous calls and clear communication of my availability. I have spent **hours** attempting to obtain reimbursement and assistance, without resolution. My vehicle is now **back in the shop**, and this matter remains unresolved. Additionally, although I have paid my vehicle payment to remain current, I am requesting **reimbursement of this payment**. This expense was incurred as a direct result of GM’s failure to provide timely service, a comparable loaner, and effective concierge assistance during a documented safety-related vehicle failure. I paid under necessity to mitigate further harm, and reimbursement is appropriate to fully resolve this matter. I am requesting: • Reimbursement for fuel expenses related to the loaner vehicle • Reimbursement of the vehicle payment made under necessity • A written explanation for the concierge communication failures • Assurance that safety-related failures are handled promptly • Confirmation that this complaint has been escalated
