PROBLEMS WITH MASTER BRAKE CYLINDER AND ACCELERATION SKID CONTROL.*MR THE VEHICLE WAS TAKEN TO THE DEALER BECAUSE THE BRAKE PEDAL WAS LOW AND SPONGY. A MASTER CYLINDER HAD BEEN PREVIOUSLY BEEN INSTALL MAY 2003. IN ADDITION THE ARS LIGHT WOULD ILLUMINATE INTERMITTENTLY WHICH CAUSED THE ENGINE TO LOSE POWER. THE ENGINE WOULD IMMEDIATELY RESTART ITSELF AND THE TACHOMETER WOULD RISE FROM ZERO TO THE CORRECT SETTING. SOMETIMES THE VEHICLE WOULD STALL COMPLETELY BUT WHEN THE CONSUMER REMOVED THE KEY AND RESTARTED IT AFTER SEVERAL MINUTES THERE WOULD BE NO REPEAT PROBLEM WITH THE ASR (ACCELERATION SKID CONTROL). *NM

Tires
THE FIRST TIRE WAS REPLACED WITHIN A MONTH OF PURCHASE DUE TO A BUBBLE ON THE SIDE. THE TIRES WERE THEN ONLY USED FOR SHORT CITY TRIPS. WHEN THE TIRES WERE DRIVE AT HIGHWAY SPEEDS FOR TWO HOURS THE THREAD SEPERATED COMPLETELY FROM THE SIDEWALLS..( DOT NUMBER: TIRE SIZE: 245-45Z-17 )
DURING THE REMOVAL AND INSTALLATION OF THE AIR FILTER HOUSING WHILE SERVICING THE VEHICLE, IT IS POSSIBLE TO MISROUTE THE PREFORMED VACUUM HOSE AND DAMAGE THE CHECK VALVE IN THE VACUUM HOSE. IF THE CHECK VALVE IS DAMAGED, LOSS OF SUFFICIENT BRAKE POWER ASSIST WILL OCCUR.
Consequence & remedy
Consequence: LACK OF SUFFICIENT BRAKE POWER ASSIST WILL INCREASESTOPPING DISTANCE AND COULD RESULT IN A VEHICLE ACCIDENT.
Remedy: REPLACE THE PREFORMED VACUUM HOSE WITH A NEWLY DESIGNED PREFORMED HOSE WITH A RELOCATED CHECK VALVE WHICH WILL ELIMINATE THE POSSIBILITY OF THE CHECK VALVE BEING DAMAGED.
