NHTSA Complaint #11659736 — 2019 TOYOTA CAMRY

Two weeks prior, car began rough idling at stop-lights, intermittently. Then one morning, after refueling, the car sputtered and failed to start. The MIL light came on, with display warnings: “Charging System Malfunction” and Steering Power Low”. Car eventually started and barely made it to Carlsbad (CA) Toyota. DTC code pulled was P0171: “System Too Lean Bank 1”. It was diagnosed with low or leaking high-pressure reading for the high-pressure fuel rail. They replaced all four high-pressure direct injectors. However, idle roughness persisted until they replaced the canister purge valve. Car has only used Costco top-tier fuel. Injectors should not have failed at 47,000 miles; likely defective. Fuel pump was replaced years ago under recall, and I was told that fuel pump pressure was fine.
