    The contact owns a 2024 Chevrolet Blazer EV. The contact stated that while his wife was driving approximately 15-20 MPH and pulling into the driveway, the brake pedal was depressed, but the vehicle failed to respond. The vehicle entered the garage, and struck equipment along with the garage wall, causing structural damage. The contact stated that the front driver's side air bag failed to deploy and the Forward Collision Avoidance system failed to engage as expected. The vehicle was towed to the dealer, where the contact was informed that no braking system failure was found; however, the contact believed that the failure was not identified because the system had rebooted prior to arrival at the dealer. The vehicle was in the process of being repaired at the dealer's body service center. The contact associated the failure with NHTSA Action Number: EA26006 (Service Brakes). The failure mileage was approximately 20,800.

  2. Filed Aug 26, 2026Failure Aug 24, 2026Bellaire, TXAutomatic emergency brakingCrash

    There was a wreck up ahead, and two tow trucks with their emergency lights flashing were blocking the left two lanes. Traffic was stop-and-go due to the existing wreck. I was traveling in the lane to the right of the tow trucks as I approached. I stopped about 1–2 car lengths behind them. When traffic started to move, I began to move forward and advanced about a car length when the automatic emergency braking (AEB) activated and slammed on the brakes, even though the path in front of me was clear. The person behind me rear-ended me. Luckily, no one was physically hurt, but there is damage to our car that now has to be repaired, along with all the headache that brings. If this had happened at higher speeds, it could have resulted in serious injuries. My family’s safety and the safety of others are definitely at risk because of this phantom braking. I would welcome an inspection of the black box and AEB. Feel free to contact me if you can facilitate this. The vehicle has not been inspected by anyone yet. There were no warning lamps or messages prior to the phantom braking. However, this has happened previously; this is the first time it resulted in a wreck. From what I’ve seen online, this appears to be a common problem, and the dealership does not have a definitive fix.

    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.

    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.

    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.

  8. Filed Feb 13, 2026Failure Jan 1, 2026Frisco, TXUnknown or other

    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.

  10. Filed Jan 3, 2026Failure Mar 10, 2025Ponemah, MNAutomatic emergency braking, Warnings

    While driving, most often at dawn/dusk and commonly with cruise control engaged, the vehicle will falsely detect a vehicle ahead when none is present. It then triggers sudden Automatic Emergency Braking along with a crash/forward-collision indicator, causing an abrupt speed drop of 15–20 mph. This is a major safety concern for my family and me while commuting in our family vehicle. If a vehicle behind us follows too closely and does not brake as rapidly as this faulty feature activates, it could cause a severe rear-end collision, or the driver may swerve into the other lane and collide with other vehicles to avoid hitting my vehicle, which has suddenly decreased speed. Other safety concerns related to this faulty braking feature include passenger whiplash and strains when the vehicle suddenly decelerates, instability on wet/snowy/icy roads, and the loss of an important safety feature. This vehicle safety feature cannot be used due to faulty braking.

    I was pulling out of my parents' driveway with my sister, who is almost 7 months pregnant in the passenger seat. Before we could get down the driveway, my car VIOLENTLY slammed itself into park to the point that I was convinced I had to have hit someone. No warnings no nothing, just WHAM, causing my lower back to feel tweaked now. After jumping out and seeing nothing, I immediately brought my car to the dealership for inspection. When I arrived, I was told that the sensors are just too sensitive, and the gentleman helping me also has the same vehicle. He said his wife hates the car and turns off all safety features in order to drive the car. You want me to turn off all the safety features to prevent a crash because it is turning itself on and could cause one? I do not feel comfortable operating this vehicle with myself in the car, let alone the two very young nephews and my pregnant sister, who I frequently drive around. I have already brought the car in for this reason and they claim there is nothing they can do.

    This forward collision system will engage at inappropriate times when there is no crash concern. This vehicle has routinely engaged in a highway setting locking up the brakes and forcing the vehicle to a full stop on the highway with vehicles at speeds of 60+mph causing a grave safety risk and an immanent risk of serious injury or death from a serious highspeed crash. This software simply does not work and is not designed and programmed properly. It should not be on the road and shouldnt be used in a public setting. Each instance of my safety concern there was not a vehicle withing the proper distance that a crash was going to occur.

    My son was driving in stop and go traffic on I-95 and he rear-ended another car. No safety features activated: i.e. dash warning lights, audible noise, auto breaking. Last week I was at teh dealer for the recall that effected the Emergency Breaking system. Talking with the dealer some updated turns the auto system off, or otherwise adjust the settings that I have prior. Backing out of the driveway the car lock up the breaks when it sees my trash can, but not on the highway? The dash warning lights randomly light up with nothing in front of me. I know the system does not prevent every accident, but it seems to pick and chose what it warns about. It is more a hazard then a help in its present state.

    See attached document for complaint. I am writing to formally notify you, pursuant to the California Song-Beverly Consumer Warranty Act (California Civil Code§§ 1790 et seq.), that my 2024 Chevrolet Blazer EV, VIN 3GNKDHRK4RSXXXXXX is subject to an active safety recall N252503010 for the parking brake system. GM has acknowledged the defect, but no genuine repair or remedy Is available. I have already experienced problems with the parking brake, which substantially impair the safety, use and value of the vehicle. Due to the severity of this defect, I have placed the vehicle at the dealership, Woodland Motors, and it will remain there until GM completes the buyback process. I refuse to drive it because it is unsafe. I further understand that GM has instructed the dealership to adjust the depth sensor as so-called remedy. This adjustment has no bearing on the parking brake defect and cannot be reasonably be considered a repair nor the taping of brake lines that they also instructed to do. It does not address the safety risk or brake failure or unintended activation. Under California Civil Code§ 1793.2, the manufacturer must repair any defect that substantially impairs the use, value, or safety of the vehicle within a reasonable number of attempts and within a reasonable period of time. Since GM has no remedy and cannot provide a repair, it is impossible to comply with this requirement. Accordingly, I hereby demand that GM immediately: Repurchase my vehicle for the full purchase price, including sales tax, registration, finance charges, and any incidental or consequential damages. In addition, I request GM immediately provide me with a loaner vehicle or GM-paid rental until this matter is resolved, as it is unsafe to operate my current vehicle. If GM fails to resolve this matter promptly, I will retain legal counsel and pursue all available remedies, including attorney's fees, court costs and civil penalties under California Civil Code §1794.
