An unexpected engine shutdown while driving can lead to loss of power steering, braking assist, and critical safety systems, dramatically increasing the chance of a collision. This comprehensive article delves into every aspect of the GM Engine Stall Risk Recall from its origins and technical causes to the repair process, owner responsibilities, legal considerations, and long‑term implications for drivers and the automotive industry. Whether you own an affected GM vehicle or are researching safety recalls, this guide will equip you with the knowledge necessary to protect yourself, save money, and maintain confidence behind the wheel.
A. Historical Context of the Recall
Understanding why GM initiated this recall begins with examining early reports, internal investigations, and regulatory involvement.
A. First Customer Complaints: In late 2024, several owners reported their engines stalling unexpectedly on highways and residential streets, often without warning lights or prior indicators.
B. Internal Data Review: GM’s quality assurance team analyzed warranty claims and dealership service records, identifying a clustering of stall incidents in models equipped with the 2.0L turbocharged four‑cylinder engine.
C. Engineering Assessment: Specialists conducted bench testing of affected fuel pumps, electronic control modules (ECMs), and wiring harnesses to pinpoint failure modes.
D. Regulatory Probe: The National Highway Traffic Safety Administration (NHTSA) opened an investigation under Recall ID 25V-123, prompting GM to expedite its corrective measures.
E. Public Announcement: On March 15, 2025, GM formally announced the recall, notifying owners via mailed letters, dealer bulletins, and online VIN lookup tools.
B. Affected Models and Production Details
Not all GM vehicles are included in this recall. Owners can confirm applicability by model, year, powertrain, and Vehicle Identification Number (VIN).
A. Model Years: 2019–2022 Chevrolet Malibu, Equinox, and GMC Terrain with turbocharged engines.
B. Engine Type: 2.0L Turbo I4 – identified by engine code LSY in VIN positions 8–11.
C. Transmission Pairings: 9‑speed automatic transmissions calibrated to the affected ECM software.
D. VIN Range: Specific VINs beginning with “1G1ZD5” through “3GKAL” for Malibu and Equinox, and “1GKDT” through “3GKDL” for Terrain.
E. Manufacturing Plants: Flint Assembly (Malibu), CAMI Assembly (Equinox), and Spring Hill Assembly (Terrain) between September 2018 and December 2022.
F. Geographic Scope: Recall applies to vehicles registered in the United States, Canada, and U.S. territories.
C. Technical Root Causes
A clear grasp of the engineering failures helps owners understand the urgency and necessity of repairs.
A. Fuel Pump Voltage Drop: A manufacturing defect causes increased electrical resistance in the fuel pump’s wiring connectors, leading to intermittent voltage loss.
B. ECM Software Glitches: Under certain load conditions such as rapid acceleration or steep inclines the ECM may misinterpret brief voltage fluctuations as critical fuel system faults and command an engine shutdown.
C. Inadequate Grounding: Improper grounding straps between the battery, chassis, and engine block can exacerbate voltage irregularities.
D. Thermal Cycling Effects: Repeated heating and cooling cycles degrade connector contact surfaces, accelerating resistance buildup.
E. Lack of Early Detection: Existing onboard diagnostics did not flag minor voltage anomalies, delaying warning light activation until complete engine shutdown.
D. Recognizing Symptoms and Warning Signs
Early identification of potential stall conditions can prevent hazardous situations on the road. Owners should remain vigilant for these indicators:
A. Intermittent RPM Fluctuations: The tachometer needle may briefly dip or surge during normal driving.
B. Engine Hesitation: Noticeable lag or hesitation during acceleration bursts, especially from low speeds.
C. Check Engine Light Activation: Illuminated “Malfunction Indicator Lamp” (MIL) without accompanying DTC (Diagnostic Trouble Code) misfires.
D. Unresponsive Throttle: Delayed throttle response or sudden “limp mode” activation where acceleration is limited.
E. Complete Engine Stall: Sudden loss of engine power, leading to coast-in-neutral behavior without power steering or brake assist.
F. Electrical Accessory Glitches: Flickering dashboard lights or radio resets coinciding with engine anomalies.
E. Real‑World Incident Reports
While GM has not linked the recall to any fatal accidents, numerous close calls highlight the importance of prompt action.
A. Highway Near‑Misses: Several drivers reported stalling while merging or overtaking, narrowly avoiding collisions thanks to quick reaction from surrounding motorists.
B. City Traffic Stalls: Engine shutdowns at intersections forced emergency restarts by skilled drivers, but blocked lanes and raised collision risks.
C. Dealership Data: Service centers documented over 500 stall‑related repair orders within the recall VIN ranges prior to the official recall announcement.
D. Safety Center Alerts: Consumer advocacy groups issued advisories after consolidating owner complaints on public forums and social media.
E. Insurance Claims: Minor impact claims increased for vehicles experiencing stalls, with property damage typically under $2,000 per incident.
F. GM’s Remedy and Repair Procedure
GM dealerships will perform free inspections and repairs to restore safe, reliable operation for all affected vehicles.
A. Fuel Pump Module Replacement: Install an updated pump assembly with improved wiring and corrosion‑resistant connectors.
B. ECM Reprogramming: Flash the ECM with revised software algorithms that tolerate brief voltage dips without commanding an engine shutdown.
C. Ground Strap Reinforcement: Inspect and, if necessary, add supplemental grounding straps between the battery, engine block, and chassis.
D. Diagnostic Verification: Post‑repair road tests under varying load conditions to confirm stable voltage delivery and engine performance.
E. Service Documentation: Technicians will update the vehicle’s service history with recall completion records and NHTSA campaign codes.
G. Owner Responsibilities and Next Steps
Affected owners must verify recall status and schedule repairs without delay to ensure their safety and maintain vehicle value.
