Complaint Summary
FUEL/PROPULSION SYSTEM
Owner Narrative
GM Flier PIP6071A - continued engine misfire/chugging/buck/skip under load, going up hills, trying to pass, etc. Was taken to shop January 2025 ~90,000 with these symptoms. Charged for spark plug replacement (visit 1). Taken back January 2026 ~150,000 miles, charged for ignition coil 1 and spark plugs. Immediately returned as problem persisted, spark plugs replaced (visit 3). February 6 2026, same problem as before, spark plugs replaced (visit 4). February 18 2026, currently in shop, problem persisting, trying to say it is the other 3 ignition coils, even after I requested they check O2 sensor and inspect catalytic converter.
