2007 Chevrolet Impala SERVICE BRAKES, HYDRAULIC

TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATE THAT WHEN DRIVING 60 MPH DOWNHILL OR AT ANY INCLINE, THE VEHICLE WOULD HESITATE TO STOP WHEN THE BRAKES WERE DEPRESSED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIANS WERE UNABLE TO DIAGNOSE THE FAILURE. THE BRAKES AND ROTORS WERE REPLACED YET THE FAILURE PERSISTED. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 2,000. UPDATED 06/13/11 *BF UPDATED 06/27/11

I NOTICED THAT ALL OF A SUDDEN WHEN I WOULD TRY TO STOP MY CAR WOULD SHAKE OR HESITATE TO STOP. I THOUGHT IT WAS MY BRAKES. AFTER TRYING TO PARK AND THE BRAKES NOT STOPPING AT ALL. I TOOK THE CAR TO REPAIR SHOP TO BE FIXED. FIRST I WAS TOLD IT WAS THE MASTER CYLINDER AFTER REPLACING THAT THE CAR STILL WOULD NOT STOP. SO I WAS TOLD IT WAS THE HYDRAULIC ABS SYSTEM AND THAT ALL THE BRAKES AND ROTORS NEEDED TO BE REPLACED. THE DEALERSHIP DOESN'T HAVE THE PART IT IS ON BACKORDER DUE TO THE HIGH VOLUME OF THE PART. THAT SAYS TO ME THERE IS A PROBLEM THAT CHEVY NEEDS TO BE RESPONSIBLE FOR AND CORRECT BEFORE A SERIOUS ACCIDENT HAPPENS. *KB

HAVE HAD ISSUES WITH WARPING ROTORS ON A 2007 LTZ WITH ONLY 50,XXX MILES ON IT. THIS IS A SAFETY ISSUE AS THE INFERIOR PRODUCT (GM BRAKE ROTORS) MAKE THE CAR SHUTTER AND SHAKE, WHICH CAUSES THE DRIVER TO ALMOST LOSE CONTROL. THIS HAS BEEN GOING ON FOR TOO LONG GM. MY 2003 SILVERADO HAS THE SAME ISSUES WITH THE BRAKES. GM - READ YOUR CUSTOMERS REVIEWS AND FIX THIS PROBLEM! I FOR ONE LIKE TO BUY AMERICAN, BUT HAVE SINCE CONSIDERED A DIFFERENT ROUTE SINCE MY FAMILY'S SAFETY IS BEING COMPROMISED WITH THE INFERIOR BRAKE COMPONENTS THAT GM HAS IN THEIR VEHICLES. *TR

I HAVE A 2007 CHEVY IMPALA WITH BRAKE AND TIRE ISSUES. I HAVE OWNED THIS VEHICLE SINCE IT WAS 2YRS OLD WITH ABOUT 32,000 MILES ON IT. IN THE FIRST YEAR OF OWNING IT I HAD TO REPLACE BRAKES ROTORS DUE TO WARPING FOUR TIMES AND TIRES DUE TO POUNDING THREE TIMES. AFTER FILING A COMPLAINT WITH CHEVY ON THEIR WEB SITE AND GETTING NO RESPONSE AND SEEING OTHER WEB BASED COMPLAINT SITE WITH SIMILAR COMPLAINTS, I AM SENDING THIS TO YOU. CHEVY TELLS ME THAT THESE PROBLEMS ARE CAUSED BY HARD BRAKING WHICH ISN'T THE CASE, I HAVE BEEN DRIVING THE SAME WAY FOR OVER 25YRS AND HAVE NEVER HAD THIS PROBLEM. AFTER SPENDING THOUSANDS OF DOLLARS TO TRY AND CORRECT THE PROBLEM I GAVE UP AND HAVE BEEN DRIVING THE VEHICLE THE WAY THAT IS FOR AWHILE NOW. RECENTLY BECAUSE THE TIRES WERE POUNDING SO MUCH AND THE BRAKES SHAKING SO MUCH AT HIGHWAY SPEED, IT WAS HARD TO CONTROL THE VEHICLE. I HAD TO REPLACE THE ROTORS AGAIN WHICH STARTED PULSATING AGAIN WITHIN A THOUSAND MILES OR SO. I HAVE TALKED WITH OTHER IMPALA OWNER AND HAVE HEARD SIMILAR COMPLAINTS AND CHEVY DOESN'T SEEM TO CARE. THIS CAN BE A REAL SAFETY ISSUE AT HIGHWAY SPEEDS AND REPLACING TIRES AND BRAKE IS ONLY A TEMPORARY CURE. CHEVY SAYS THAT I SHOULD DO A "ROAD FORCE BALANCE", AT $70 PER, EVERY 3,000 MILE TO CORRECT THE TIRE POUNDING ISSUE. THEY HAVE NO SOLUTION FOR THE BRAKE ISSUE OTHER THAN TO NOT USE THE BRAKES I GUESS. *TR

SEVERE VIBRATION FROM THE FRONT BRAKES OF MY 2007 CHEVROLET IMPALA. OCCURS AT SPEEDS ABOVE 50 MPH, PARTICULARLY SEVER WHEN STOPPING ~70 MPH. CAR DID THIS AT 40,000, REPLACED FRONT ROTORS. AGAIN AT 80,000 MILES, AGAIN REPLACED FRONT ROTORS, NOW AGAIN AT 100K MILES. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT THE BRAKES BEGAN GRINDING. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE ROTORS HAD HOT SPOTS AND WERE WARPED. THE CONTACT WAS TOLD THAT HE WOULD BE RESPONSIBLE FOR REPAIR COSTS. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 15,921. UPATDED 3/9/11 *CN THE ROTORS WERE REPLACED TIWCE . UPDATED 07/29/11

2007 CHEVROLET IMPALA BRAKING SYSTEM GRABS AND SHAKES CAR EXCESSIVELY WHEN USING THE BRAKES TO CONTROL DESCENT DOWN MOUNTAIN ROADWAYS. THIS HAS ALSO OCCURRED DURING COMMUTING TO AND FROM WORK WHEN THE BRAKES ARE USED QUITE OFTEN. THE BRAKING SYSTEM WAS TESTED BY A CHEVROLET DEALER, THREE DAYS AFTER THE MOUNTAIN DRIVING PROBLEM. THE ROTORS AND PADS WERE IN EXCELLENT CONDITION AND NO PROBLEM COULD BE IDENTIFIED. A WEB SEARCH IDENTIFIES OTHER COMPLAINTS OF THIS SAME SYMPTOM. ALTHOUGH NO DAMAGE WAS CAUSED, THE CAR WAS OPERATING IN A VERY UNSAFE MANNER. EVEN AT 30 - 40 MPH THE CAR WAS SHAKING ENOUGH TO DEGRADE SAFE CONTROL. *TR

I OWN A 2007 CHEVY IMPALA THAT WHEN BRAKES ARE APPLIED THE STEERING WHEEL SHUDDERS. THIS HAPPENS AFTER MODERATE TO HEAVY BRAKING OR DURING DOWN-HILL BRAKING. THE DRIVER GETS A SENSE OF LOSING CONTROL OF THE VEHICLE AND TENDS TO REDUCE BRAKING WHICH MAY LEAD TO AN ACCIDENT. *TR

MANY CHEVROLET VEHICLES HAVE A LONG TERM PROBLEM WITH INADEQUATE, DEFECTIVELY MANUFACTURED BRAKE ROTORS CAUSING THE VEHICLE TO VIOLENTLY SHAKE, CHATTER, VIBRATE, ETC., WHEN THE BRAKES ARE APPLIED. THE CHEVROLET BRAKE CHATTER, SHAKE, PULSATING, ROUGHNESS PROBLEM REPORTED BY MANY CHEVROLET OWNERS IS NOT ONLY AN ANNOYING PROBLEM BUT ALSO A SAFETY PROBLEM!!!! THE FOLLOWING IS A PERSONAL EXPERIENCE NEARLY RESULTING IN A SERIOUS ACCIDENT PRIMARILY BECAUSE OF DEFECTIVE BRAKES ON MY 2007 CHEVROLET IMPALA VEHICLE. RECENTLY WHILE TRAVELING ALONG AN INTERSTATE HIGHWAY WITH MY WIFE DRIVING, WE WERE SUDDENLY FACED WITH AN PANIC STOPPING REQUIREMENT BECAUSE OF BACKED UP TRAFFIC ON A CURVE. MY WIFE APPLIED THE BRAKES HEAVILY AND THE CAR WENT INTO SUCH A VIOLENT FRONT SHAKING FIT THAT SHE PANICKED AND RELEASE THE BRAKE TO STOP THE SHAKING AND HAD TO SWERVE TO AVOID STOPPED CARS IN FRONT OF US. THE NHTSA SHOULD FORCE CHEVROLET TO RECALL ALL CHEVROLET VEHICLES WITH THIS PROBLEM AND CORRECT IT BEFORE MAJOR ACCIDENTS HAPPEN WITH LOSS OF PROPERTY AND LIFE. THIS PROBLEM IS COMMON TO MANY CHEVROLET VEHICLE AS REPORTED ON MANY WEB SITES BUT BECAUSE IT IS OFTEN JUST AN ANNOYING CONCERN MOST PEOPLE DON'T CONSIDER THE SAFETY ASPECTS OF THIS PROBLEM UNTIL THEY ARE FACED WITH A SITUATION AS DESCRIBE ABOVE. NOTE: PLEASE DO NOT ASSOCIATE THIS CHATTER, SHAKING, VIBRATING BRAKE PROBLEM DUE TO DEFECTIVE BRAKE ROTOR DESIGN/MANUFACTURE WITH THE ACTIVATION OF THE ANTI-BRAKE SYSTEM. THIS PROBLEM SHOWS UP WITH JUST NORMAL BRAKE ACTIVATION. *TR

2007 IMPALA. ROTORS REPLACED 3 TIMES. POLICE BRAKES WERE INSTALLED BUT THE ROTORS WARPED. THEY DID LAST LONGER. THE DEALER REPLACED THE POLICE ROTORS AND THEY WARPED WITHIN 100 MILES. THE ROTORS WERE CUT YESTERDAY AND I WOULD BET THEY WILL BE WARPED WITH IN 2 WEEKS. *TR

GOING DOWN HILL BRAKES STARTED CHATTERING. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. WHENEVER THE CONTACT APPLIES THE BRAKES WHILE DRIVING DOWNHILL, SHE HEARS A THUMPING SOUND. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY STATED THAT THE ROTORS NEEDED TO BE REPLACED. THE FAILURE STILL PERSISTS. THE SPEED WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 29,000. UPDATED 10/13/09. *LJ UPDATED 10/15/09.

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. HE STATED THAT WHEN APPLYING PRESSURE TO THE BRAKE PEDAL, THE VEHICLE BEGAN TO SHAKE. THE DEALER REPLACED THE ROTORS TWICE WITHIN 10,000 MILES. NONE OF THE REPAIRS HAVE REMEDIED THE FAILURE AND THE BRAKES ARE NOT FUNCTIONING PROPERLY. THE FAILURE MILEAGE WAS 19500 AND THE CURRENT MILEAGE WAS 36335. UPDATED 10/20/09 *CN THE CONSUMER STATED THE FRONT AND REAR ROTORS WERE WARPED. UPDATED 10/22/09.*JB

FRONT ROTORS ARE WARPED AT 22,000 MILES ON THE CAR. IT APPEARS THAT THE ROTORS ARE EITHER UNDERSIZE, MADE OF POOR STEEL, AND OR IMPORTED FROM CHINA. THERE IS NO REASON FOR THE ROTORS TO HAVE FAILED AND BE RESURFACED. AS A MECHANIC THIS CONDITION CAUSED A SIGNIFICANT SAFETY ISSUE UNDER HIGHWAY SPEED BRAKING TO A STOP. MY WIFE THOUGHT IT WAS THE ROAD BUT INSTEAD IT WAS A ROTOR SHIMMY. I THOUGHT THE CAR WAS GOING TO SHIMMY APART AND BRAKE STEERING TIE ROD LINKS AT THE TIME IT HAPPENED. THERE WAS NO WAY I WAS GOING TO LET UP ON THE BRAKE OR I WOULD HAVE HIT THE CAR IN FRONT OF ME. INSTEAD I RODE OUT THE VIOLENT SHIMMY AND GRINDING SOUNDS COMING FROM THE FRONT END. THE CONCERN I HAVE IS THAT OTHER PEOPLE WOULD NOT IDENTIFY THE SHIMMY FOR WHAT IT IS LIKE MY WIFE DID AND THINK IT WAS THE ROAD. I FEEL THAT IF THE ROAD WAS WET I WOULD HAVE LOST CONTROL OF THE CAR. *TR

FRONT DISC BRAKES MAKE A GRINDING NOISE WHEN APPLIED ESPECIALLY GOING DOWNHILL. ROTORS AND PADS ARE IN PERFECT CONDITION. DEALER SAID THAT THEY ARE NOTED FOR THIS PROBLEM YET THEY WILL DO NOTHING TO CORRECT AS THERE IS PLENTY OF PAD LEFT. NOISE IS VERY BOTHERSOME. IT SOUNDS AS IF THE PADS ARE WORN OUT AND STARTING TO GRIND INTO THE ROTORS. THIS IS DEFINITELY A FACTORY DEFECT AND GM SHOULD OFFER A NEW TYPE OF PADS TO ELIMINATE THE NOISE! THESE ARE THE FACTORY ORIGINAL PADS ON THE CAR. *TR

SHAKING FROM FRONT END WHEN BRAKES APPLIED. CAN BE VERY VIOLENT WHEN GOING DOWNHILL. SEEMS TO BE COMMON AMONGST IMPALA'S, DEALERS REFUSE TO COVER THE BRAKES. I JUST BOUGHT IT SECOND OWNER AT 25,000 AND IT EVEN WENT THROUGH "GM CERTIFIED" WITH THIS SHAKING BRAKE PROBLEM. *TR

THE BRAKES WERE APPLIED WHILE DESCENDING A STEEP GRADE. THE FRONT END OF THE VEHICLE STARTED SHAKING VIOLENTLY. WHEN THE DEALER WAS CONTACTED THEY STATED IT WAS PROBABLY WARPED ROTORS AND THEY PROBABLY NEED TURNED. THIS WILL BE THE SECOND TIME THOSE ROTORS WILL BE TURNED. THIS IS ALWAYS THE MANUFACTURERS CURE FOR THIS PROBLEM. IT'S JUST A DELAY UNTIL THE VEHICLE RUNS OUT OF WARRANTY IN ANOTHER 5,000 MILES. I'VE HAD THIS PROBLEM WITH WARPED ROTORS ON VARIOUS VEHICLES BEFORE AND MY EXPERIENCE HAS BEEN THAT IT NEVER FIXES THE PROBLEM. BECAUSE THIS IS A KNOWN ON GOING PROBLEM WHICH OCCURS ON ALL MAKES AND MODELS OF VEHICLES AND ALSO BECAUSE IT HAPPENS TO ONE OF THE VEHICLES MOST CRITICAL SYSTEMS, THE PRACTICE OF TURNING ROTORS TO SOLVE ROTOR WARPING OR ROTOR SHUDDER PROBLEMS SHOULD BE BANNED FOR ALL VEHICLES. *TR

ON 1-11-07 THE CONTACT WAS DRIVING AT 45 MPH, UNDER DRY CONDITIONS, WHEN ANOTHER VEHICLE PULLED OUT IN FRONT OF HIM. WHEN HE APPLIED THE BREAKS THEY FAILED AND WOULD NOT STOP THE VEHICLE.
