1997 Chevrolet Tahoe Steering

POWER STEERING OVER-ASSIST, BAD EVO SENSOR. *AK

WHILE DRIVING STEERING WOULD ACTUALLY JUMP & VEHICLE WOULD GO INTO ONCOMING TRAFFIC. TOOK VEHICLE TO DEALERSHIP & INFORMED BY SERVICE MANAGER THAT STEERING SHAFT WAS THE CAUSE OF JUMPING. IT CAN BE REPAIRED.*AK

WHILE MAKING TURNS STEERING SENSOR GOES OUT INTERMITTENTLY, AND STEERING BECOMES VERY LOOSE, NO RESISTANCE. CONSUMER CHECKED OUR COMPLAINTS DATABASE, AND ON JANUARY 3 FOUND 40 COMPLAINTS WITH SAME PROBLEM. *AK

WHEN TURNING LEFT OR RIGHT STEERING WHEEL WILL JERK IN THAT DIRECTION AND CAUSE VEHICLE TO TURN MORE THAN INTENDED, LIKE SOMEONE IS JERKING IT OUT OF CONSUMER'S HAND. CONSUMER STATED THIS WA SVERY DANGEROUS. DEALER SAID IT WAS A SENSOR THAT NEEDED TO BE REEPLACED. PLEASE PROVIDE ANY FURTHER INFORMATION.*AK

STEERING POSITION SENSOR FAILED, CAUSING THE POWER STEERING SYSTEM TO LOSE RESISTANCE AT SPEED. INCIDENT OCCURRED WHILE DRIVING ON A SWEEPING LEFT HAND TURN. I WAS APPLYING CONSTANT LIGHT LEFT HAND PRESSURE ON THE STEERING WHEEL WHEN THE POWER STEERING SYSTEM LOST RESISTANCE AND THE WHEEL TURNED FREELY AND QUICKLY TO THE LEFT. BEFORE I REGAINED CONTROL I HAD MOVED 1/2 LANE TO THE LEFT. THE PROBLEM WAS VERY INTERMITTENT AT FIRST BUT GREW INCREASINGLY MORE REGULAR. THE STEERING WOULD SEEM TO TWITCH AND CAUSE MOMENTARY LOSS OF FEEL. I*AK FINALLY REPLACED THE STEERING POSITION SENSOR AND THE PROBLEM WAS FIXED. WHEN I PURCHASED THE REPLACEMENT PART AT THE CHEVROLET DEALERSHIP, THE PARTS COUNTERMAN NEW EXACTLY WHAT I WAS TALKING ABOUT AND COMMENTED THAT IT MUST BE A BIG PROBLEM BECAUSE THEY HAD A WHOLE BIN OF STEERING POSITION SENSORS. IT IS MY CONTENTION THAT THIS SHOULD BE A RECALL ITEM. THE SUDDEN LOSS OF STEERING CONTROL CAN BE VERY UN-NERVING.

STEERING BECOMES SPASTIC AT TIMES. IT FELT LIKE I WAS DRIVING ON ICE. THE STEERING HAS ALSO BECOME UNUSUALLY LOOSE MAKING DRIVING DIFFICULT.*AK

STEERING BECOMES OVER SENSITIVE CAUSING VEHICLE TO OVER STEER. VEHICLES WITH THE SAME PROBLEMS ARE AS FOLLOWS. 1997-1999 CHEVROLET TAHOE, 1997-1999 GMC YUKON, 1997-1999 CHEVROLET 1500 TRUCKS, 1997-1999 GMC TRUCKS. ANY GM VEHICLE WITH AT V8 GASOLINE POWERED ENGINE WILL HAVE THIS FAILURE. THERE ARE 1000S OF COMPLAINTS IN YOUR DATABASE AND THIS ADDS TO THEM ONLY NOW YOU ARE AWARE THAT ADDITIONAL MODELS ARE AFFECTED AS WELL. IF THERE IS A FATALITY RESULTING FROM THIS DEFECT THEN ALL CORPORATIONS AND AGENCIES AWARE OF THE DEFECT TIME OF THE DEATH WILL BE LIABLE FOR CIVIL DAMAGES. IT IS IN THE BEST INTEREST OF THE CONSUMER TO SEE THIS DEFECT IS REPAIRED BEFORE SOMEONE IS KILLED DUE TO BUREAUCRATIC RED TAPE.*AK

EA99011, INTERMITTENTLY WHILE DRIVING, STEERING SYSTEM MALFUNCTIONED, CAUSING VEHICLE TO WANDER WHICH COULD RESULT IN A CRASH. DEALER COULD NOT DETERMINE CAUSE. *AK *SLC

THE EVO VALVE IN STEERING WHEEL FAILED, CAUSING WHEEL TO BECOME VERY LOOSE.*AK

CAR HAS ERRATIC STEERING RESPONSIVENESS, ESPECIALLY WHEN CHANGING LANES OR NEGOTIATING A CURVE. IT FEELS LIKE THE STEERING WHEEL SKIPS. IT COULD EASILY CAUSE AN ACCIDENT.

MY PROBLEM SEEMS TO BE SUMMARIZED BY NHTSA ACTION NUMBER: EA99011. THE RESISTANCE ON STEERING WHEEL IS ERRATIC, ESPECIALLY AT HIGHWAY SPEEDS. *AK

WHEN NEGOTIATING CURVES (WHILE DRIVER IS TURNING STEERING WHEEL AND HOLDING FAIRLY CONSISTANT PRESSURE ON THE WHEEL TO MAINTAIN THE TURN), THE STEERING WHEEL WILL SUDDENLY TURN (TWITCH) IN THE DIRECTION YOU ARE TURNING. THIS SOMETIMES CAUSES AN OVERSTEER TO CORRECT . PROBLEM IS WORSE WHEN VEH. IS COLD AND DOES IT MOSTLY AROUND 35 MPH ALTHOUGH REGULARLY DOES IT AT ALL SPEEDS ALSO. MY SENSE OF THE PROBLEM IS NOT THAT THE VEHICLE IS "STEERING ITSELF" , BUT THAT THERE IS A SUDDEN CHANGE IN BOOST TO THE STEERING (DEFECTIVE SPEED SENSITIVE PWR STEERING?) AND SINCE THE DRIVER IS HOLDING PRESSURE ON THE WHEEL IN A CURVE, THE SUDDEN CHANGE IN STEERING BOOST CAUSES THE DRIVER TO OVERSTEER AND THAN OVERCORRECTION IN STEERING, WHICH TO SOME COMPLAINANTS APPARENTLY IS PERCEIVED AS A LOSS OF STEERING. MY WIFE PERCEIVES IT AS A LOSS OF STEERING AND I DRIVE THE VEH AS MUCH AS HER AND CAN TELL YOU THE LOSS OF STEERING IS IN THE MIND DUE TO "PUCKER FACTOR"! I CAN TELL YOU WITHOUT A DOUBT THAT THE PROBLEM IS VERY REAL AND I HAVE HAD 1 OR 2 NEAR MISSES WITH A CAR AND JERSEY BARRICADE AS I OVERSTEERED WITH THE SUDDEN CHANGE OF BOOST. WHAT YOU NEED TO UNDERSTAND IS THAT THE SUDDEN CHANGE IN BOOST PROBABLY OCCURS REGULARLY AT THE APPROPRIATE SPEED, ( AS DESIGNED INTO THE SPEED SENSITIVE STEERING SYSTEM), BUT WHEN THE DRIVER HAS TURNING PRESSURE ON THE STEERING WHEEL, AND THE NORMAL STEERING WHEEL BACK-PRESSURE IS SUDDENLY RELEASED (OR SIGNIFIGANTLY REDUCED)THE 1ST ACTION IS A SUDDEN OVERSTEER (AS THOUGH SOMEONE QUICKLY JERKED THE WHEEL LOOSE FROM YOUR HANDS IN THE SAME DIRECTION YOU ARE ALREADY TURNING). I SEE MANY SIMILIAR COMPLAINTS IN THE COMPLAINTS DATABASE AND A NHTSA ACTION # EA99011 OPEN INVESTIGATION SINCE MAY 12, 1999, SEEMS THAT THIS IS A DEFINITE WIDESPREAD PROBLEM. IS THERE A FIX ON THE HORIZON? I SEE THAT SOME DEALERS HAVE REPLACED THE STEERING SPEED SENSOR, BUT IT IS NOT CLEAR IF THAT IS THE CURE. ANY SUGGESTIONS?*AK

STEERING JERKS LEFT OR RIGHT WITHOUT WARNING -INTERMITTENT PROBLEM. SEEMS TO BE WORSE GOING AROUND CORNERS,BUT CAN HAPPEN GOING STRAIGHT. *AK

WHILE TRAVELING ON HIGHWAY CONSUMER NOTICED THAT STEERING WHEEL WAS MOVING ALL OVER THE PLACE. *AK

ERRATIC POWER STEERING OPERATION. BECOMES EXTREMELY LOOSE WHILE DRIVING.SHUTTING OFF THE TRUCK AND RESTARTING WILL RESOLVE THE PROBLEM FOR A SHORT PERIOD. FEELS LIKE THE SLIGHTEST TOUCH TO THE STEERING WHEEL COULD TURN THE VEHICLE OVER. ALSO HAS BEGUN AN ERRATIC "TWITCH".*AK

WHEN MAKING A TURN POWER STEERING BOOSTS THE TURN, CAUSING THE TURN TO BE FURTHER THAT EXPECTED. DEALER HAS INSPECTED VEHICLE, AND THE MANUFACTURER HAS BEEN NOTIFIED.*AK THE CAUSE FOR POWER STEERING BOOSTING IS FOUND TO BE FAILURE IN ELECTRONIC VARIALBE ORIFICE SYSTEM (EVO). *YH

DUE TO A LEAK IN STEERING GEAR BOX STEERING SYSTEM MALFUNCTIONED AND VEHICLE TURNED TO THE LEFT. VEHICLE LOST CONTROL AND RESULTED IN COLLISION. *AK

BOTH TIMES THE STEERING SENSOR FAILED WAS AT HIGHWAY SPEEDS. THE FIRST TIME I WAS SWITCHING LANES AND ALL OF A SUDDEN IT OVER CORRECTED AND ALMOST SENT ME INTO THE DITCH AT 65 MPH. THE SECOND TIME MY WIFE WAS TRAVELING ON THE INTERSTATE AT 65 MPH AND TURNED THE WHEEL A LITTLE AND IT SENT HER INTO THE NEXT LANE CUTTING OFF ANOTHER VEHICLE. THE FIRST TIME I HAD IT FIXED THE GUY SAID "OH YEAH WE HAVE BEEN HAVING PROBLEMS WITH THESE." THE NEXT TIME I HAD IT FIXED I FIGURED THEY WOULD JUST REPLACE IT SINCE THEY KNOW THERE IS A PROBLEM WITH THEM, BUT THEY CHARGED MY $150 PARTS AND LABOR. I AM GOING TO CONTACT THE MANUFACTURER NEXT. IT WAS VERY DANGEROUS AND I CANNOT BELIEVE SOMETHING LIKE THIS ISN'T BEING CORRECTED.

POWER STEERING SENSOR HAS BEEN REPLACED TWICE AT 34000 MILES AND AGAIN AT 60000 MILES. WHEN MAKING A TURN STEERING WHEEL WILL JERK AWAY FROM TURN.*AK

WHILE TRAVELING AT ALL SPEEDS STEERING WHEEL & COLUMN GAVE IN & BECAME VERY LOOSE. COULD CAUSE AN ACCIDENT. DEALER HASN'T LOOKED AT THE VEHICLE, HE WAS ONLY ASSUMING WHAT THE PROBLEM WAS. *AK *ML

AT HIGHWAY SPEEDS, STEERING WHEEL JERKS LEFT ON ITS OWN. WITHOUT A STRONG GRIP ON THE WHEEL COULD CAUSE LOSS OF CONTROL.

STEERING EOV SENSOR FAILURE CAUSED STEERING TWITCHES OR JERKS WHEN CHANGING LANES. YH

EA99011, DUE TO A DEFECTIVE STEERING SPEED SENSOR, STEERING SYSTEM MALFUNCTIONED, CAUSING ERRATIC STEERING WHILE DRIVING IN HIGH SPEEDS. THIS COULD RESULT IN A CRASH. DEALER WAS AWARE OF PROBLEM, AND WOULD EXTEND THE WARRANTY ONLY IF THE HE COULD DUPLICATE THE PROBLEM. COMMON PROBLEM. PLEASE PROVIDE FURTHER INFORMATION. *AK

EA99OII/ERRATIC POWER STEERING OPERATION: VEHICLE WOULD JERK WHILE TRAVELING AT HIGHWAY SPEED . DEALER/MAANUFCTURER WERE NOT CONTACTED AT THIS TIME. *AK

CONSUMER WAS TRAVELING 55MPH ON THE HIGHWAY WENT TO MAKE A SLIGHT TURN, AND THE STEERING WHEEL WAS FIGHTING WITH HIM. AFTER TURNING THE IGNITION OFF AT A REST AREA, THE PROBLEM WENT AWAY FOR AWHILE. AFTER IT REOCCURED, OWNER HAD FAULTY EVO SENSOR REPLACED, NO PROBLEMS SINCE. *AK*ML
