2004 Hyundai Sonata Brakes Problems

Your brake pedal went to the floor without stopping the vehicle while driving downhill at low speed, forcing the driver to intentionally crash into a pole to avoid a worse accident. The brake warning light was on, but the airbags didn't deploy during the crash, and both occupants were injured. The vehicle wasn't repaired or diagnosed at a dealer, though the manufacturer was contacted about the failure.

Your brakes failed while driving, and your mechanic had to fabricate and install a new brake line to fix it. When you brought the car back for inspection, the mechanic found severe corrosion underneath that would prevent it from passing inspection. You believe your vehicle should have been covered under a specific NHTSA recall for suspension issues, but the dealer says your VIN wasn't included.

When you press the brake pedal, your car occasionally accelerates for a moment before actually braking. You've confirmed you're not accidentally pressing the gas pedal. This has happened at low speeds (under 25 mph) shortly after starting to drive on local roads, but it's inconsistent and you're not sure exactly when it occurs.

DT: WHILE DRIVING ON SEPTEMBER 4, 2005 ON 1-95 2004 AT 6 MPH THE HYUNDAI SONATA WAS INVOLVED IN A NEAR MISS ACCIDENT DUE TO THE BRAKES LOCKING. THE CONSUMER'S WAS IN THE MIDDLE LANE AND HAD DECIDED TO OVERTAKE THE CAR AHEAD. THE CONSUMER MOVED TO THE LEFT LANE AND NOTICED THAT THE SPEED WAS MORE THAN 75 MPH. THE CONSUMER STEPPED ON THE BRAKES TO SLOW DOWN AND THE VEHICLE SWERVED TO THE RIGHT, MADE A 360-DEGREE TURN, SKIDDED, AND MERCIFULLY STOPPED ON THE GRASSY SHOULDER. IT WAS A MIRACLE THAT NO CAR BUMPED THE CONSUMER'S VEHICLE DURING THIS EPISODE. THE CONSUMER HEARD A POPPING SOUND AND THOUGHT THAT ONE OF THE TIRES HAD BLEW OUT. THE CONSUMER GOT OUT OF THE VEHICLE TO INSPECT THE TIRES AND SAW SKID BURNS. THE CONSUMER WENT BACK TO THE VEHICLE AND TRIED TO DRIVE ON THE SHOULDER. THE CONSUMER THEN PROCEEDED TO DRIVE ON THE HIGHWAY AGAIN. ON LABOR DAY, SEPTEMBER 5, 2005 THE CONSUMER CALLED THE HYUNDAI DEALER IN ALEXANDRIA, VIRGINIA WHERE THE VEHICLE WAS PURCHASED. THE CONSUMER TALKED TO THE SALESMAN WHO SOLD THEM THE VEHICLE LAST YEAR. THE CONSUMER TOLD HIM WHAT HAPPENED AND HE SUGGESTED THAT THE CONSUMER CALL A HYUNDAI SERVICE OUTLET FOR A SERVICE CHECK-UP APPOINTMENT. THE CONSUMER CALLED BOB BELL HYUNDAI IN GLEN BURNIE FOR A SERVICE APPOINTMENT AND THE RECORDING SAID THEY WOULD CALL HIM WITHIN THE HOUR. THIS WAS THE SECOND TIME THAT THE BRAKES LOCKED.

MY VEHICLE WAS INVOLVED IN AN ACCIDENT IN DECEMBER 2004, WHILE DRIVING MY 2004 HYUNDAI SONOTA. TRAFFICE WAS HEAVY AND A DRIVER, 3 CARS AHEAD, SLAMMED ON HER BRAKES AS ALL THOSE BEHIND HER DID. I HAD AMPLE TIME TO STOP BUT THE ANTI-LOCK BRAKES REPEATEDLY KEPT TURNING. MY CAR CONTINUED TO HIT THE DRIVER IN FRONT OF ME AND MY CAR ATTEMPTED TO CLIMB ON THE BACK OF THE OTHER CAR. THE REPETITIVE HITTING OF THE CAR IN FRONT OF ME CAUSED EXTENSIVE DAMAGE TO MY CAR. THE BRAKES OF BEEN CHECKED THREE TIMES, THE LIGHT CONTINUES TO COME ON AT INTERMITTENT TIMES, YET THE DEALERSHIP CONTINUES TO INFORM ME THAT THEIR IS NOTHING ON THE DIAGNOSTIC MACHINE. THE BRAKES CONTINUE TO ACT UP ON DRY SURFACES STILL. I AM AFRAID TO DRIVE MY CAR BUT CANNOT SEEM TO CONVINCE THE HYUNDAI DEALERSHIP THAT THERE IS AN ISSUES WITH THE BRAKES GRABBIND AND CONTINUE TO ROTATE. THE IMPACT, FROM THE REPETITIVE HITTING OF THE CAR IN FRONT OF ME CAUSED IT TO BE TOTALED. MY CAR, EVEN AFTER EXTENSIVE FRAME DAMAGE AND SHIFTING OF THE ENTIRE MOTOR CARRIAGE, WAS NOT TOTALLED. IT SHOULD BE ALSO NOTED THAT WHEN THE INSURANCE CARRIER HAD THE CAR DELIVERED TO THE DEALERSHIP FOR MOTOR REPLACEMENT THAT THEY WERE NOT ADVISED OF BRAKE PROBLEMS. I WAS SENT TO HOSPITAL FOR A CHECKUP AS THE REPETITIVE HITTING CAUSED THE SEATBELT TO CAUSE NUMBNESS IN MY LEFT ARM AND NECK. I WAS TREATED AND RELEASED WITH A PRESCRIPTION FOR MUSCLE RELAXERS FOR A FEW DAYS.*AK
