General Motors is recalling tens of thousands of compact electric crossovers after discovering that their electronic parking brakes may not reliably hold the vehicle in place. The defect affects the Chevrolet Blazer EV, a high-profile model in the company’s push into battery-powered SUVs, and raises fresh questions about how quickly new EV platforms are being pushed to market.
The recall centers on a wiring problem that can prevent the rear parking brake from engaging or releasing properly, creating a risk of rollaway if the vehicle is parked on an incline. While no injuries have been confirmed in the available reports, the scope of the campaign and the nature of the defect make it a significant safety story for owners and for the broader EV market.
What GM Found In The Blazer EV’s Parking Brake System
Regulators were formally notified after General Motors determined that a safety defect exists in certain 2024 and 2025 model year Blazer EVs. In a Part 573 filing, General Motors reported that the issue involves the rear parking brake wiring harness, which can be damaged or chafed in normal use. That damage can interrupt the signal that tells the electronic parking brake to clamp the rear wheels, leaving the vehicle at risk of moving even when the driver believes it is secured.
Consumer-focused reporting has filled in the scale of the problem, with multiple outlets describing a campaign that covers more than 40,000 vehicles. One analysis of the recall notes that the affected vehicles are model-year 2024 and 2025 Blazer EVs and that the rear parking brake wiring harness may become damaged or corroded, potentially preventing the brake from engaging or releasing as intended, a risk highlighted in coverage of the affected Blazer crossovers. The technical root cause is not a software glitch but a physical routing problem that leaves the harness vulnerable in everyday driving.
How Many Vehicles Are Involved And What Owners Should Expect
The numbers attached to this recall are strikingly consistent across regulatory and legal summaries. A detailed breakdown of the campaign states that General Motors, LLC is recalling about 40,233 2024–2025 Chevrolet Blazer EV vehicles because of the damaged parking brake wiring harness. A separate consumer advisory echoes that figure, noting that Chevrolet has recalled 40,233 examples of the Blazer EV and that owners will be able to have any necessary safety repairs completed at no cost. Other coverage rounds the figure, describing a campaign affecting more than 40,000 Blazer EVs, but the underlying scope is the same.
For owners, the practical question is what happens next. Regulatory summaries explain that Dealers will reroute or replace the harness and that the work will be performed free of charge, a remedy spelled out in the same notice that cites the 40,233 vehicles. A consumer law advisory adds that General Motors, LLC has announced a safety recall for over 40,000 Chevrolet Blazer EV Vehicles Due to Parking Brake Wiring Problems and that the fix will focus on correcting the routing of the parking brake wire harness. Until the repair is completed, owners are being urged to use extra caution when parking, including turning the front wheels toward the curb and ensuring the vehicle is in Park on level ground.
Why The Blazer EV Recall Matters For GM’s EV Strategy
The Blazer EV is not the only Chevrolet product to face scrutiny over braking systems, and the pattern is becoming harder for shoppers to ignore. Earlier in the year, General Motors was reported to be recalling more than 40,000 Chevrolet electric vehicles over a brake issue, according to coverage dated Jun 30, 2025. Separate reporting on the Blazer EV campaign, including a piece dated Jul 9, 2025 with a Jul 10, 2025 Read Time: 1 Min note, framed the situation as Chevy Recalls 40,000 Blazer EVs for Parking Brake Defect, underscoring how quickly the story has spread among body shops and repair professionals. Together, these reports paint a picture of an automaker grappling with quality control as it scales up new electric platforms.
The official defect report, filed on Jun 24, 2025, shows that Jun has become a pivotal month for General Motors as it works through the implications of the parking brake problem on its compact crossover lineup. That Part 573 document confirms that Jun 24, 2025 is when General Motors formally decided that a defect related to motor vehicle safety exists in certain 2024–2025 model year vehicles, a step that triggered the broader recall machinery. Additional consumer coverage dated Jun 30, 2025, which describes 40,000-Plus Chevrolet Blazer EVs being recalled and notes that owner notification will begin in Aug, reinforces how quickly the issue moved from internal engineering concern to public safety campaign, as reflected in the Jun 30, 2025 coverage. For GM, the stakes go beyond one compact crossover, touching consumer confidence in its broader EV rollout at a time when competition in the segment is intensifying.
