Chevrolet Blazer EV Problems and Complaints Report (Model Years 2024–2026)

The Chevrolet Blazer EV is GM's electric midsize crossover SUV built on the same Ultium platform as the Cadillac Lyriq. Retail deliveries began in late 2023/early 2024 (2024 model year); there are no production 2021–2023 models for retail customers. Early 2024 production faced significant launch issues, including a GM-issued stop-sale in December 2023 due to software quality problems, which delayed broader availability until early 2024 after major over-the-air (OTA) and dealer updates.

As of mid-2026, the Blazer EV has accumulated notable NHTSA complaints and multiple recalls, primarily in electrical/electronics, brakes, and software categories—typical early Ultium-platform teething pains but amplified by the vehicle's high-volume launch. Consumer Reports rates the 2024 and 2025 Blazer EV well below average (or among the least reliable EVs) for predicted reliability, with major trouble spots in in-car electronics, electrical accessories, and related systems. The 2026 model is predicted to remain “much less reliable than average” based on prior years' data.

Owner forums (BlazerEVForum.com, Reddit r/BlazerEV, Facebook groups) and long-term tests (e.g., Edmunds) show a split: many 2025–2026 owners report strong ownership after updates, praising ride, range, and performance, while early adopters describe repeated dealer visits, stranding events, and frustration with first-gen software/electrical gremlins. Some vehicles have been lemon-law buybacks or required extended service.

Major Categories of Reported Problems

1. Software, Infotainment, and Display Issues (Most Prominent Early Issue)

• Frozen/flickering touchscreen, black/blank screens, rear camera failures (blue screen or error icons), apps rearranging or lagging, random warning lights, and vehicle “waking up” after shutdown.
• Forward collision system causing sudden/unexpected braking (even with no obstacle).
• These led to the December 2023 stop-sale; Edmunds' long-term 2024 tester recorded 23 fault codes (none always dashboard-visible) after just two months, with infotainment “meltdown,” power window failures, and stranding risks. Many fixed via full-vehicle programming (VWP), infotainment USB updates (TSB 24-NA-092 to SQBR5+), or OTA, but intermittent issues persist for some.

2. Electrical, High-Voltage (HV), and Battery System Warnings

• “Service high voltage system” warnings, battery fault codes, cooling valve faults, or sudden loss of power/charging capability.
• Telematics module failures and 12V battery-related no-start quirks (vehicle slips into anti-theft mode).
• Intermittent HV warnings post-update or during charging. These have resulted in towing, extended dealer downtime, and some lemon-law claims.

3. Charging Problems

• DC fast-charging sessions starting then stopping prematurely (“unable to charge”), slower-than-expected curves, or handshake failures at public stations.
• Level 2/home charging dropouts, charge-port door randomly opening/closing, voltage sensitivity issues. Reboots or different stations often help; some tied to software.

4. Braking and Parking Brake Issues (Major Recall Category)

• Rear parking brake wiring harness damage/corrosion from flexing → unintended parking brake activation while driving, loss of parking brake function, “service parking brake” messages, or inability to shift out of Park.
• Rear wheel lock-up risk in rare cases. This prompted a large recall (see below). Some owners also report forward collision sudden braking.

5. Build Quality, Noise, and Other Issues

• Rattles/squeaks from underbody panels, doors, dash, or cargo area (more noticeable in quiet EV cabin).
• Muffled hands-free phone microphone (highway speeds).
• Minor fit/finish or trim flex complaints.

Real-world range often trails EPA estimates in cold weather/highway use (common EV trait), but many owners find it competitive once software is updated.

Recalls (as of May 2026)

The Blazer EV has had multiple recalls (at least 4–5 major ones for 2024–2025 models), focused on software, brakes, and chassis components. Key examples:

• Parking brake wiring harness (25V433000, announced ~June 2025; ~42,000 vehicles, 2024–2025 Blazer EV) — Wiring may corrode/damage from flexing, risking unintended brake application or loss of function while driving. Dealers inspect/repair/replace harness. Follow-up recall 26V031000 (Jan 2026; ~20 vehicles) for incorrect parts installed during the first repair.
• Door strikers/latches (24V737000, Oct 2024; certain 2025 Blazer EV and related GM models) — Improperly heat-treated strikers may fracture, risking door opening while driving.
• Suspension/chassis (24V487000, ~June 2024; certain 2024 Blazer EV) — Related to harness or component issues (details tied to early production).
• Software/charging-related campaigns (multiple TSBs and the Dec 2023 stop-sale fix) — Full-vehicle module and infotainment updates to resolve glitches.
• Additional minor equipment recalls (e.g., owner's manual download via radio reset).

Check your VIN for open recalls at NHTSA.gov or Chevrolet's owner portal. All fixes are free (dealer or OTA where applicable).

Owner Sentiment and Context

• Early 2024 models were hardest hit (stop-sale, 23+ faults in tests, extended shop time). Many owners needed multiple dealer visits for VWP/infotaiment updates.
• 2025–2026 models generally improved dramatically with accumulated OTA fixes and better dealer familiarity; some owners report “flawless” ownership.
• Common praise: Smooth ride, strong acceleration, spacious cabin, and value once issues are resolved. Frustrations center on dealer EV knowledge gaps and intermittent software gremlins. No widespread class-action lawsuit specific to the Blazer EV (unlike some Ultium-related cases), but individual lemon-law filings and NHTSA complaints exist.

Bottom line: Like the Lyriq, the Blazer EV's first years reflect typical new-EV platform challenges—especially software and electrical systems—exacerbated by a rushed launch. The 2024 stop-sale and parking brake recall were significant, but most issues are addressed via warranty/OTA updates. 2025–2026 models are notably improved for many owners. Prospective buyers should verify full software/recall history on any used or new unit, test drive extensively (including charging), and consider extended warranty.
