WHEN I FIRST BOUGHT MY 1998 CHEVROLET LUMINA, ALL OF THE BRAKE LIGHTS WERE WORKING PROPERLY. HOWEVER, A FEW WEEKS LATER I WAS DRIVING AND A MAN TOLD ME THAT MY BRAKE LIGHTS WERE OUT. THE TOP BRAKE LIGHT HAS ALWAYS WORKED, BUT THE TWO SIDE LIGHTS AND THE REVERSE LIGHTS DO NOT WORK. THIS HAS BEEN AN ONGOING PROBLEM EVER SINCE I NOTICED IT. WE HAVE TIRED THE FOLLOWING: SWITCHING THE LIGHT BULBS, CHANGING THE FUSES, AND GETTING A PROFESSIONAL WORK DONE. HOWEVER, NOTHING WORKS. THE NEW FUSE MAKES THE LIGHTS WORK FOR LESS THAN A DAY IF I'M LUCKY, BUT THEN THE FUSE BLOWS; AND THE EXPERTS HAVE NO IDEA WHAT IS WRONG. I LIVE IN MILWAUKEE, WI, AND HAVE SEEN OVER TEN CARS WITH THE EXACT SAME PROBLEM! I HAVE GOTTEN PULLED OVER AND TICKETED 3 TIMES NOW, AND HAVE HAD TO PAY OVER $100 IN FINES, AND AT LEAST $300 AT THE AUTO SHOP, JUST FOR THE BRAKE LIGHT PROBLEM. ALSO, THE REVERSE LIGHTS HAVE NEVER BEEN FIXED, NOT EVEN WITH A NEW FUSE PUT IN. GM NEEDS TO FIX THIS PROBLEM. I CANNOT AFFORD TO GET ANY MORE TICKETS, OR FIX THE PROBLEM MYSELF. SEEING THAT MANY CARS WITH THE SAME PROBLEM HAS TO BE A MANUFACTURES PROBLEM, AND I WOULD LIKE SOMETHING DONE ABOUT THIS PLEASE. THANK YOU FOR TAKING THE TIME TO ADDRESS MY CONCERNS.

MY BRAKES HAVE ALWAYS MALFUNCTIONED IN MY VEHICLE. THEY HAVE BEEN MAINTAINED AND WILL GO OUT WHEN I AM TURNING OR TRYING TO STOP. I HAD THEM CHECKED FOR 4 YEARS STRAIGHT- PADS CHANGED AND COMPLETELY SERVICED- MY MECHANIC SAID IT IS SOME COMPUTER SENSOR IN THE BRAKES THAT GOES OUT IN THIS PARTICULAR CHEVY. IT IS EXPENSIVE AND A DEFECT. I HAVE WENT THROUGH INTERSECTIONS- AND BEEN SO CLOSE IN REAR ENDING SEVERAL VEHICLES BECAUSE OF MY INABILITY TO STOP MY CAR.

I BOUGHT THIS CAR USED WITH 32,000 MI. FROM THE BEGINNING BRAKES WOULD NOT GRAB IN THE RAIN, THE BRAKE PEDAL WAS EXTREMELY HARD. THE DEALER SAID NOTHING WAS WRONG AND THAT'S THE WAY THIS CAR IS. I WAS TOLD THAT I WAS NOT USE TO 4 WHEEL DISC BRAKES. (I DRIVE A 4 WHEEL DISC CAR AT WORK.) I INSISTED THAT SOMETHING WAS WRONG. DEALER TURNED THE FRONT ROTORS WHICH DID NOT HELP. I INSTALLED HIGH PERFORMANCE DISC PADS ON ALL FOUR WHEELS WHICH HELPED A LOT BUT ONLY FOR ABOUT 20000 MILES. THE BRAKES USE TO WHEN THEY GOT WET. THIS CAR IS UNSAFE IN WET WEATHER! *TS ***DIMSII IVOQ ENTRY POSTED AFTER 12-12-02 CUT OVER TO ARTEMIS***762002

I PURCHASED MY VEHICLE USED AND IT STILL HAD 1000 MILE WARRANTY FROM THE DEALER. WHEN I GOT THE CAR THERE WAS A PROBLEM WITH THE FUEL PUMP SO THEY REPLACED IT. BEFORE I EVEN GOT OUT OF THE PARKING LOT THE (VIBRATION SHUDDER HOSE) WENT BAD. OR AT LEAST THAT IS WHAT THE GUY AT THE SERVICE AREA TOLD ME THE NAME WAS. THEY HAVE REPLACED THAT. AND FOR ALMOST TWO YEARS NOW I HAVE BEEN FIGHTING WITH THEM THAT THE POWER STEERING HAS BEEN WHINING. ALSO THE BRAKES DO NOT STOP TO WELL IN THE RAIN. I TRAVEL A LOT AND WE GO THROUGH BRAKES LIKE WATER. WE ALSO HAD THE AC COMPRESSOR GO OUT LAST YEAR DURING THE SUMMER. THE CAR WAS ONLY 4 YEARS OLD. WE KEEP OUR CAR UP VERY WELL. I DO NOT UNDERSTAND ALL THESE PROBLEMS. I KNOW THIS MAY NOT SEEM LIKE BIG PROBLEMS BUT WHEN I KEEP MY CAR UP AND HAVE BEEN FIGHTING WITH THE DEALER DUE TO WHINING THIS IS FRUSTRATING.

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM

I WAS GOING 55 MPH ON BELTWAY. I DISCOVERED THAT MY BRAKES WERE VERY HARD TO PUSH AND COULD NOT STOP. PULLED OFF TO SHOULDER AND COULD NOT PICK UP ANY ACELERATION. I HAD THE CAR TAKEN IMMEDIATELY TO DEALER FOR CHECK-UP. THE DEALER (FOX) ADVISED THAT THE BRAKE BOOSTER HOSE FROM THE MASTER BRAKE CYLINDER BECAME LOOSE AND WAS "CRIMPED" NEAR THE HOOD AND FIRE WALL. THIS RESULTED IN THE FLOW OF VACUUM PRESSURE BEING COMPROMISED AND STOPPING. THE DEALER ADVISED THAT THE BRAKE BOOSTER HOSE HAD TO BE "REPOSITIONED." THIS CORRECTED BOTH PROBLEMS OF FAILED BRAKING AND LACK OF ACCELLERATION. THE DEALER WOULD NOT OR COULD NOT FULLY EXPLAIN IF THIS WAS A MANUFACTURING PROBLEM OR WAS A RESULT OF HUMAN ERROR WHEN WORK IS PERFORMED ON THE CAR. THE DEALER WOULD NOT REPLACE THE "CRIMPED" BOOSTER HOSE. LOST OF BRAKES WHEN GOING HIGHWAY SPEEDS WAS QUITE UPSETTING. I THOUGHT I WOULD PASS THIS COMPLAINT ON FOR YOU REVIEW AND ANY ACTION YOU DEEM FIT. IF THIS IS A SAFTY PROBLEM, PERHAPS A TECH BULLETIN OR WARNING SHOULD BE ISSUED BY CHEV. THANK YOU. PLEASE FEEL FREE TO CONTACT ME FOR ANY OTHER INFORMATION REQUIRED ON YOUR PART.

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DRUM

I HAVE BEEN HAVING PROBLEMS WITH THE REAR BRAKES ON MY 1998 LUMINA. THEY WOULD DRAG AND MAKE A METAL TO METAL NOISE. I TOOK THE CAR INTO FRONTIER CHEVROLET 5 TIMES FOR THIS PROBLEM. AS I SAID, THE BRAKES MADE A METAL TO METAL NOISE, THE BRAKES WOULD DRAG, SOMETIMES EVEN SKIDDING THE TIRES ON DRY PAVEMENT. THIS HAPPENED WITH LIGHT TO MODERATE BRAKE PRESSURE ON THE PETAL. THE LAST TIME I WAS INTO FRONTIER CHEVROLET, THE SHOP FORMAN TOLD ME THAT HE WAS NOT GOING TO FIX IT BECAUSE HE DIDN'T SEE ANYTHING WRONG. I CONTACTED GM AT THEIR CUSTOMER SERVICE HOTLINE ON AT LEAST TWO OR POSSIBLY THREE OCCASIONS. I WAS TOLD THAT THEY COULDN'T REACH THE SHOP FORMAN AND THEY WOULD GET BACK TO ME. THEY NEVER DID. I LIVE IN MONTANA WHERE ICY ROADS ARE A PROBLEM IN THE WINTER. WITH WINTER WETHER SETTING IN I GAVE UP ON THE DEALER AND TOOK THE CAR INTO AN INDEPENDENT SERVICE CENTER TO HAVE THE BRAKES FIXED. I DIDN'T WANT TO CHANCE THE BRAKES LOCKING UP ON ICY ROADS AND SENDING ME OUT OF CONTROL. THE INDEPENDENT MECHANIC SOON DISCOVERED METAL SHAVINGE ON THE DRUMS AND OTHER BRAKE PARTS. HE SAID THE SHOES WERE RUBBING ON THE INSIDE OF THE DRUMS WHEN THE PETAL WAS DEPRESSED. THIS CAUSED THE SHOES TO BIND INSIDE OF THE DRUMS, WHICH CAUSED THE BRAKES TO DRAG AND POSSIBLY LOCK UP. HE MEASURED THE ORIGINAL SHOES AND THE REPLACEMENT SHOES AND FOUND THAT EVEN WITH 31,000 MILES OF RUBBING ON THE INSIDE OF THE DRUMS, THE ORIGINAL SHOES WERE .007 WIDER THAN THE REPLACEMENTS. MY NEIGHBOR TOLD ME OF A PONTIAC GRAND AM THAT SHE OWNED THAT HAD THE SAME PROBLEM. SHE ALSO TOOK THE CAR INTO THE DEALER, WHO COULD FIND NOTHING WRONG. AN INDEPENDENT MECHANIC ( IN ANOTHER CITY), TOLD HER THAT GM HAD INSTALLED THE WRONG SHOES ON HER CAR. THIS LEADS ME TO BELIEVE THAT THIS IS A WIDESPREAD PROBLEM FOR GM. WHILE THIS DIDNOT CAUSE AN ACCIDENT, IT VERY EASILY COULD HAVE IF I HADN'T HAD THE CAR FIXED AT MY OWN EXPENSE, EVEN THOUGH THE PARTS SHOULD HAVE BEEN COVERED UNDER WARRANTY. I HOPE YOU WILL LOOK INTO THIS PRO

THIS PROBLEM WAS ADDRESSED PROPERLY BY THE DEALERSHIP, BUT THE PROBLEM STILL EXISTS. I WOULD APPRECIATE AN OPPORTUNITY TO DISCUSS THE PROBLEM IN DEPTH WITH A NHTSA REPRESENTATIVE DUE TO THE PROBLEM DATING BACK TO A 1993 LUMINA, A 1995 LUMINA AND NOW THE 1998 LUMINA. I HAVE HAD A LOT OF EXPERIENCE WITH BRAKE SYSTEMS AND FEEL THAT I CAN POSSIBILITY HELP TO ANSWER SOME OF THE COMPLAINTS OF DRIVERS STATING THAT THEIR BRAKE PEDAL WENT TO THE FLOOR BOARD. WHEN I HAD MY CAR SERVICED, THE SERVICEMAN STATED THAT HE HAD COMPARED MY VEHICLE BRAKES AND FOUND THEM TO BE ALMOST THE SAME AS ON THE NEW VEHICLES. I DO AGREE THAT SOME OF THE NEW VEHICLES HAVE THE SAME BLEED DOWN PROBLEM AS MY VEHICLE AND THAT IS MY CONCERN. THE SERVICE MANAGER AGREED THAT HE WAS CONCERNED ABOUT THE OPERATION OF MY BRAKES AND DECIDED TO REPLACE THE MASTER CYLINDER AND ARRANGED FOR ME TO HAVE A CAR TO KEEP ME FROM DRIVING THE CAR HOME . ALTHOUGH THE PROBLEM WAS ONLY AN UNUSUALLY FAST PEDAL BLEED DOWN THE MANAGER STATED THAT HE TOO, HAS A CONCERN ABOUT THE BRAKE PROBLEM AND HAD ORDERED A BRAKE MASTER CYLINDER. THE NEW CLYLINDER DID REDUCE THE REQUIRED BRAKING EFFORT BUT THERE IS STILL EXCESSIVE BRAKE PEDAL BLEED DOWN UNDER LIGHT PEDAL FORCE. I THINK I CAN HELP TO DETERMINE THE PROBLEM AND SUGGEST A CORRECTION. I WILL DISCUSS THIS WITH THE LEADER SERVICE MANAGER. I OWNED A 1993 LUMINA AND EXPERIENCED THE BRAKE PEDAL "GOING TO THE FLOOR BOARD" WHICH VERY NEARLY CAUSED ME TO HAVE TWO MAJOR ACCIDENTS. THE DEALERSHIP KEPT ASSURING ME THAT MY CAR BRAKES WORKED AS GOOD AS ALL THE NEW CARS. WITH THE HELP OF THE ST. LOUIS BETTER BUSINESS BUREAU AND A BRAKE TEST OFF OF OIL CHANGE RAMPS, THE BBB REPORT CONVINCED GM TO BUY BACK MY 1993 LUMINA. I FEEL THAT THE ONLY WAY TO COMMUNICATE WITH THE NHTSA IS BY REVIEWING THE MECHANICS OF THE BRAKE SYSTEM, BRAKE FLUID FLOW AND TEST PROCEDURES. PLEASE CONTACT ME FOR FURTHER INFORMATION. HOW MANY OWNERS HAVE HAD SIMILIAR PROBLEMS.
