Chevrolet Recalls Blazer EV Again Due to Parking Brake Wiring Issue

Chevrolet has announced a new recall involving the Blazer EV, after discovering that some vehicles previously repaired under an earlier recall may still have a safety-related defect. The issue centers on the rear parking brake wiring harness, which can become damaged over time and potentially lead to serious safety risks.

What’s the problem?

The original recall dates back to June 2025, when General Motors recalled over 40,000 Chevrolet Blazer EVs from the 2024 and 2025 model years. At the time, GM found that the rear parking brake wiring harness could be exposed to damage or corrosion.

If the wiring fails, two dangerous situations may occur:

  • The parking brake could activate unexpectedly while driving
  • Or the parking brake may not work at all

Either scenario increases the risk of an accident, prompting GM to act.

Why is there another recall now?

Unfortunately, GM has now confirmed that some vehicles were not repaired correctly during the first recall.

The root cause was traced to an error in GM’s electronic parts catalog, which allowed dealers to order an incorrect replacement wiring harness. While the part technically fit, its routing did not properly limit movement. Over time, this excessive flexing could cause the wiring to shorten, break, or fail again during normal driving.

Which vehicles are affected?

The latest recall affects:

  • 2024 Chevrolet Blazer EVs built between July 4, 2023, and March 3, 2024
  • 2025 Chevrolet Blazer EVs assembled between September 11, 2024, and October 9, 2024

Only vehicles that were previously repaired using the incorrect harness are included in this follow-up recall.

How was the issue discovered?

A GM quality manager identified the problem on October 13, 2025, and the issue was officially reported through GM’s internal Speak Up For Safety (SUFS) system.

This safety reporting program was introduced during the period when GM was rebuilding trust following the infamous ignition switch scandal, which occurred early in CEO Mary Barra’s tenure. That crisis led to 124 confirmed deaths and 275 injuries, highlighting the importance of early detection and transparent reporting. See more photos

What is GM doing to fix it properly this time?

GM says affected vehicles will now receive a new and improved wiring harness at no cost to owners. The updated part includes:

  • An overmold sleeve at the bend point, where previous failures occurred
  • Improved routing to reduce flexing and movement
  • Corrected part numbers in the service bulletin
  • Updates to the electronic parts catalog to prevent future ordering mistakes

Dealers have been instructed to carefully follow the revised repair process to ensure the issue does not return.

Sales context: Blazer EV vs gas Blazer

Despite being part of GM’s broader electric vehicle push, the Blazer EV has struggled to match the popularity of its gas-powered sibling.

In the U.S. market last year:

  • Gasoline Blazer deliveries: 46,531 units
  • Blazer EV deliveries: 22,637 units

The electric Blazer rides on GM’s BEV3 platform, which is also used by several other GM EVs, including the ultra-luxury Cadillac Celestiq, priced north of $400,000.

Pricing and performance highlights

For the 2026 model year, Chevrolet continues to offer the Blazer EV in multiple trims:

  • LT (front-wheel drive or all-wheel drive)
  • RS (rear-wheel drive or all-wheel drive)
  • SS (dual-motor performance model)

Key specs include

  • Up to 334 miles (538 km) of range for the RS RWD
  • 0–60 mph in just 3.4 seconds for the SS trim
  • Starting price: $44,600 (before destination charges)

Chevrolet also counts the Blazer EV as one of four electric vehicles in its 2026 lineup, or five if the BrightDrop electric delivery vans are included, though those models have seen limited sales so far.

Final thoughts

While the Blazer EV remains an important part of Chevrolet’s EV strategy, this recall highlights the growing pains of launching new electric platforms at scale. GM says it has corrected the underlying issues and reinforced internal safeguards to prevent similar problems in the future.

Owners of affected vehicles are encouraged to contact their local Chevrolet dealer to confirm whether their Blazer EV needs the updated repair.

FAQs

Why was the electric SUV recalled?

The recall happened because a wiring part connected to the parking brake can get damaged. When that happens, the parking brake may stop working or turn on by itself, which can be dangerous while driving.

It is related to an older recall. Some vehicles were already repaired before, but the repair was done using the wrong replacement part, which caused the problem to come back.

If your vehicle was built between certain dates in 2023 or 2024 and was repaired during the earlier recall, it may be affected. The best way to know is to check with a dealer using your VIN number.

If the wiring fails, the parking brake could behave in an unsafe way. It is better to get the vehicle checked as soon as possible if it is part of the recall.

No. The repair will be done free of charge for affected vehicles. This includes replacing the wiring harness with a better-designed part.

The earlier repair used a wiring part that allowed too much movement. Over time, this movement could cause the wire to bend too much and break during normal driving.

The new repair uses a wiring harness with extra protection at the bend point. This helps reduce movement and prevents the wire from wearing out again.

No. The issue only affects the parking brake system. It does not change the vehicle’s speed, range, battery life, or charging.
