Known issues on the 2004 Suburban 2500. Six recalls sit on the federal record for this year, and two of them land on the same brake booster. The hydraulic brake booster accumulator can crack and part from its assembly, letting fluid escape from the booster circuit; a relief valve bore machined out of specification in that same booster housing can fracture its seal and raise the pedal effort needed for a given stop. A third recall covers a fuel rail damper retainer clip on the 8.1L that can break and let the damper loosen into a fuel leak. Complaints total 406: 146 electrical, 82 brakes, 29 steering.
