Chevrolet Blazer EV 1st gen Problems, Recalls & Lemon Law

On December 22, 2023, GM halted sales of all 2024 Blazer EV vehicles and asked owners who had already taken delivery to schedule a mandatory dealer software update. GM acknowledged that 'a limited number' of owners had experienced software quality issues — but independent reviewers documented as many as 23 simultaneous fault codes in a single test vehicle, spanning the radio, body control module, driver motor control, and brake system control module. Confirmed failures included infotainment screens going completely blank while driving, DC fast charging failing or dropping to Level 2 rates, and backup cameras stopping mid-use. GM issued Customer Satisfaction Program DCS6901 (NHTSA file MC-11000286, May 2024), requiring dealers to perform a full USB-based software reflash across all vehicle modules. Sales resumed in March 2024 after the reflash campaign was underway. If your vehicle was delivered before the stop-sale lifted and you experienced these issues on multiple occasions, document each repair visit and service date — those visits may support a lemon law claim.

Yes. NHTSA recall 25V433 (issued June 25, 2025) covers approximately 29,865 2024 model year Blazer EV vehicles. The defect: the rear parking brake wiring harness, supplied by Lear Electrical Systems De Mexico, routes with sharp wire bends that cause abrasion, damage, and corrosion over time. A corroded or broken wire can send an erroneous signal that activates the parking brake actuator while the vehicle is moving, causing sudden deceleration or rear wheel lockup. Alternatively, the harness failure can disable the parking brake entirely, creating a rollaway risk. GM's own field data included 97 complaints and two confirmed rear-wheel lock-up events before the recall was issued. The remedy is dealer inspection of the harness, rerouting and installation of anti-abrasive tape, or full harness replacement if damaged — at no charge. Note: a follow-on recall (26V031, January 2026) found that some vehicles repaired under 25V433 received an incorrect replacement harness due to an error in GM's electronic parts catalog. If your vehicle was repaired under 25V433 before January 2026, confirm with your dealer that the correct part was used. Check your VIN at nhtsa.gov for current recall status.

Owners of 2024 Blazer EV vehicles have filed numerous NHTSA complaints describing the automatic emergency braking (AEB) system engaging without any obstacle present — on highway approaches to overpasses, over manhole covers, at dawn or dusk, during reverse maneuvers, and with cruise control active. NHTSA complaint records include a rollover crash attributed to a false AEB activation and multiple occupant injuries from sudden unexpected braking. As of the research date for this page, no formal NHTSA safety recall has been issued specifically for Blazer EV AEB false activations, and no single documented GM remedy has resolved the issue across the affected fleet. Dealers have reprogrammed ADAS modules with mixed results, according to NHTSA complaint records. If your AEB system has triggered falsely multiple times and dealer repairs have not resolved the problem, this pattern — a safety-relevant defect subject to repeated unsuccessful repair attempts — may qualify under California's lemon law. Document each episode with date, mileage, driving conditions, and every dealer visit with the repair order.

Yes. NHTSA recall 24V320 (issued May 9, 2024) covers 2024 Blazer EV vehicles with all-wheel drive. The defect: electric motors in the rear drive units were manufactured with insufficiently insulated wires. When those wires contact each other, the resulting short circuit causes a complete and sudden loss of rear drive power. NHTSA identified the loss of drive power as a crash hazard. The remedy is dealer replacement of the rear drive unit assembly at no charge (approximately 6 hours of labor). Owner notification letters were mailed May 16, 2024. This was a multi-model recall also covering the 2024 Cadillac Lyriq, Chevrolet Silverado EV, GMC Hummer EV, and GMC Sierra EV. If your Blazer EV has experienced sudden propulsion loss more than once, or if it occurred after the recall repair was supposed to have been performed, document the date, mileage, and any warning lights and contact a California lemon law attorney for a free evaluation.

You may qualify. California's Song-Beverly Consumer Warranty Act presumes a lemon when the manufacturer cannot repair a safety defect after two or more attempts, cannot fix any other substantial defect after four or more attempts, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. The 2024 Blazer EV has had multiple overlapping defect and recall campaigns: the stop-sale software defect required dealer reflash visits; the parking brake recall (25V433) covers nearly 30,000 MY2024 units and has been followed by a second recall (26V031) for a wrong-part-used correction; false AEB events have affected owners with no consistent dealer fix available; and sudden propulsion loss was subject to a separate recall (24V320). Owners who have had two or more visits for the same safety issue, or who have been waiting 30 or more days for recall parts to become available, may have particularly strong standing. If GM cannot resolve your vehicle's defects, you may be entitled to a repurchase at the original price (less a mileage offset) with GM paying your attorney fees. This is general information only, not legal advice.

Yes. GM issued Customer Satisfaction Program DCS6901 (NHTSA file MC-11000286, May 2024) specifically to address the software failures documented across the 2024 Blazer EV fleet, including infotainment blackouts, screen flickering, backup camera failure, and DC fast-charging failures. The campaign requires an EV-certified dealer to perform a full USB-based reflash of all vehicle software modules, at no charge to you through March 31, 2026. However, some dealers reportedly failed to update the A11 radio module as part of the campaign, leaving vehicles on an outdated infotainment build even after the service was marked complete. If your screen continued going blank after the software campaign was supposedly performed, ask your dealer to confirm the specific software build version installed on the infotainment module and request that the reflash be redone completely. If your infotainment has gone blank or failed repeatedly despite dealer software updates, those visits accumulate as repair attempts under California lemon law. Keep every repair order.
