Service brakes, hydraulic:power assist:vacuum
Model years: 2001, 2002
Problem: Vehicle description: sport utility vehicles. The accumulator that is installed on the hydraulic brake booster may have been improperly manufactured. Over a period of time, this could result in leakage of the pressurized nitrogen gas from inside the accumulator.
Risk: The loss of this gas pressure could result in an abnormal noise from the left side of the dash panel when the brakes are applied, and possibly a delayed first time brake boost assist after the vehicle has been parked for a period of time, which could result in a vehicle crash.
Fix: Dealers will install an improved accumulator. Owner notification mailing began october 1, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mitsubishi at 1-800-222-0037.
