Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
CONSUMER COMPLAINED ABOUT A BRAKE PROBLEM. WHILE DRIVING ON HIGHWAY BRAKES WERE SLOW TO STOP VEHICLE. WHEN DRIVING AROUND TOWN BRAKES WORKED FINE. ALSO, WINDSHIELD WIPERS OPERATED POORLY, POWER STEERING WORKED INTERMITTENTLY. *AK
CONSUMER'S SON WHILE DRIVING AT 5MPH AND APPLYING THE BRAKES, PEDAL WENT DOWN TO THE FLOOR, AND VEHICLE WAS AT THE WALL OF THE BUILDING. INDEPENDENT REPAIR SHOP DIDN'T FIND ANYTHING WRONG WITH THE BRAKES. MODELZ71. YEAR 1999. *AK
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
ON SEVERAL OCCASIONS I EXPERIENCED A LOSS OF STEERING CONTROL. IT WAS NOT SPEED RELATED - IT HAPPENED FROM LOW TO HIGH SPEEDS. THE VEHICLE WOULD SUDDENLY JERK TO ONE SIDE. NO INSTANCE LASTED LONGER THAN ONE SECOND. MY MECHANIC DIAGNOSED THE PROBLEM AS A FAULTY EVO SENSOR. NO SENSORS ARE AVAILABLE FOR REPLACEMENT, BUT GM HAS A "KIT" THAT ELIMINATES THE SENSOR. ELIMINATION OF THE SENSOR FIXED THE PROBLEM. THE FAILURES THAT I EXPERIENCED WERE EXTREMELY SHORT IN DURATION AND CAUSED NO HARM OTHER THAN A VERY ELEVATED HEART RATE! I FEAR THAT A GREATER FAILURE WOULD HAVE RESULTED IN A CRASH. *TR

From owner reports, verbatim
I AM THE NEW OWNER OF A 1998 CHEVY K1500 Z71. MY GIRLFRIEND AND I WERE GOING TO A FOOTBALL GAME AND SHE TRIED TO CLEAN THE WINDSHIELD AND THE WINDSHIELD WIPERS WOULD NOT WORK. TWO DAYS LATER I WAS COMING HOME WHEN A RAIN STORM STARTED I TURNED ON THE WIPERS AND THEY DID NOT WORK. AFTER GETTING OUT OF VEHICLE AND PICKING UP THE WIPER BLADES THEY STARTED TO WORK. WHEN I GOT HOME I TURNED OFF THE ENGINE, AND MY GIRLFRIEND GOT INTO THE TRUCK TO LEAVE AND TAKE DAUGHTER HOME AND THE WIPERS DID NOT WORK. PICKED UP WIPERS AND THEY WORKED ONCE AGAIN. MY GIRLFRIEND SAID WHILE SHE WAS OUT WIPERS KEPT GOING OFF AND ON EVEN WITH THE CONTROL TURNED TO ON. AT ONE POINT SHE HAD TO PULL OVER IN HEAVY RAIN FOR FEAR OF HAVING A WRECK BECAUSE SHE COULD NOT SEE AND THE WIPERS HAD CUT OFF. WHEN SHE CAME HOME, SHE LOOKED ON THE INTERNET FOR RECALLS AND CAME ACROSS INFO ON OTHER 1998 CHEVY K1500 OWNERS HAVING THE SAME PROBLEM. SHE COPIED ONE RECALL BUT MY VIN WAS NOT INCLUDED. RE: RECALL 98 V 150 001/WINDSHIELD WIPER WIRING: WIPERS WORK INTERMITTENTLY, THIS CAN RESULT IN INOPERATIVE WIPERS, REDUCING A DRIVER'S VISIBILITY, AND INCREASING THE RISK OF A VEHICLE CRASH. WILL IT TAKE SOMEONE GETTING KILLED FOR A RECALL TO BE PUT OUT??

THE FRONT END OF MY TRUCK BEGAN SHAKING AT 50 MPH. TIRES WERE CHECKED BY THE DEALER AND NOTHING WRONG WAS FOUND. TIRE PRESSURE WAS 32 PSI. ABOUT TWO WEEKS LATER THE RIGHT REAR TIRE EXPLODED AT 67 MPH ON THE INTERSTATE CAUSING ME TO SWERVE ACROSS TWO LANES.

THE TIRE WAS SENT TO THE MANUFACTURER AND I WAS TOLD THE FAILURE WAS DUE TO THE TIRE BEING CUT, AND NO DAMAGES WOULD BE PAID. THE TIRE WAS SENT BACK TO ME AND I RECONSTRUCTED THE TIRE AND COULD NOT FIND ANY EVIDENCE OF A CUT. THE DOT # OF THE TIRE IS DOT V4LT M132702. *JB
