MY 2010 AUDI Q7 HAS A SERIOUS BRAKING ISSUE. WHEN THE ENGINE IS STARTED, IF YOU PUT THE VEHICLE INTO DRIVE, IT WILL ROLL FORWARD AND THE BRAKE WILL NOT STOP THE ROLLING.

MY 2010 AUDI Q7 HAS A SERIOUS BRAKING ISSUE. WHEN THE ENGINE IS STARTED, IF YOU PUT THE VEHICLE INTO DRIVE, IT WILL ROLL FORWARD AND THE BRAKE WILL NOT STOP THE ROLLING. YOU MUST WAIT ROUGHLY 1 MINUTE FOR THE VEHICLE TO NOT ROLL. THE TIME IS SHORTER IN THE SUMMER, AND LONGER IN THE WINTER. THE BRAKES DO NOT WORK, AND IT IS AS IF THE COMPUTER HAS A GLITCH. I WILL DEPRESS THE BRAKE, AND THE VEHICLE WILL ROLL FORWARD ABOUT 10 FEET. THIS HAPPENS IN BOTH REVERSE AND FORWARD. MY CONCERN IS THAT ONE COULD START THE CAR, IMMEDIATELY PUT IT INTO GEAR, AND HIT A PENDESTRIAN, CHILD, OR OTHER PROPERTY AND NOT BE ABLE TO STOP THE CAR UNLESS THEY INTUITIVELY KNOW TO PUT THE CAR IN NEUTRAL OR PARK, WHICH MOST DRIVERS WILL NOT DO. I AM WILLING TO SHOW THIS TO AN NHTSA REPRESENTATIVE. I BELIEVE THIS NEEDS TO BE INVESTIGATED AND AUDI NEEDS TO RECALL THESE CARS FOR A PROPER FIX. I CALLED AUDI'S NORTH AMERICAN HOTLINE TO REPORT THIS, AND THE RECEPTIONIST DID NOT PUT ME IN TOUCH WITH A MANAGER OR A SAFETY REPRESENTATIVE. SHE SAID THE CAR NEEDS TO GO TO THE SHOP AND BE REPAIRED. MY AUTO MECHANICS SAY THEY CAN'T REPAIR THIS, AND IT IS A MANUFACTURER PROBLEM. AUDI NORTH AMERICA STAFF SHOULD HAVE TAKEN MY INFORMATION, PASSED IT TO A MANAGER, AND CONTACTED ME, BUT THEY REFUSED TO, SAYING IT WAS A MECHANICAL ISSUE WITH MY VEHICLE. I HAVE NO OTHER OPTIONS BUT TO CONTACT NHTSA. I HAVE OWNED THIS CAR SINCE 2014, I FIRST NOTICED THE PROBLEM THEN, AND ADAPTED TO THIS PROBLEM. I SHOULD HAVE TOLD YOU MUCH SOONER THAN NOW. I APOLOGIZE. I KNOW HOW TO DEAL WITH THIS PROBLEM, BUT IF IT IS IN ANY OTHER AUDIS, THERE MAY BE PEDESTRIAN INJURIES OR DEATHS.

THIS FIRST HAPPENED ON A BUSY FREEWAY. THEN THIS HAS BEEN REPEATING FREQUENTLY. AUDI IS UNABLE TO FIGURE OUT THE PROBLEM AND ARE SUGGESTING REPLACING THE WHOLE FUEL SYSTEM WHICH MAY POTENTIALLY FIX THE PROBLEM. THEY ARE NOT SURE. I AM NOT SURE IF THIS IS A MANUFACTURING ISSUE WHICH CAN START HAPPENING TO OTHER VEHICLES. BUT THIS IS DEFINITELY A DANGEROUS SAFETY ISSUE.

MY FAMILY VEHICLE IS A 2010 AUDI Q7 TDI, PRESTIGE EDITION. THIS IS THE VEHICLE WE ALWAYS TAKE WITH THE CHILDREN, AGES 1 AND 2. RECENTLY, WE HAD AN UNKNOWN BATTERY DRAIN, AND SO TODAY I TOOK THE VEHICLE TO THE DEALERSHIP TO BE SERVICED. APPROXIMATELY 20 MINUTES INTO THE DRIVE, I HEARD WHAT SOUNDED LIKE A GUNSHOT INSIDE THE VEHICLE. I THEN REALIZED THE SUNROOF HAD EXPLODED FROM THE INSIDE AND THERE WAS GLASS EVERYWHERE. THERE WERE NO ROCKS, AND ONLY A FEW VEHICLES A SAFE DISTANCE AHEAD OF ME - EVEN SO, A ROCK WOULD HAVE HAD TO TRAVEL STRAIGHT UP AND THEN STRAIGHT DOWN TO SHATTER THE SUNROOF IN THIS MANNER. THERE WERE NO BRIDGES OR UNDERPASSES. I WAS ABLE TO MAINTAIN CONTROL OF THE CAR, DESPITE HAVING SHATTERED GLASS ALL OVER MYSELF, IN MY HAIR, COFFEE MUG, ETC. THIS IS PROBABLY THE ONLY TIME I'VE DRIVEN THE VEHICLE WITHOUT THE CHILDREN, AND AM ABSOLUTELY THANKFUL THEY WERE NOT IN THE VEHICLE AS BOTH CAR SEATS WERE COVERED IN GLASS. THE CAR WILL HAVE TO BE DETAILED BEFORE THEY CAN RIDE IN IT AGAIN DUE TO THE SHEER VOLUME OF BROKEN GLASS. I TOOK PHOTOS OF THE DAMAGE, AND THE REMAINING GLASS BENDED UPWARD ON THE EDGE OF THE DAMAGE - INDICATING IT BROKE FROM THE INSIDE-OUT. ONE DOES AS MUCH RESEARCH AS HUMANLY POSSIBLE BEFORE PURCHASING A FAMILY VEHICLE BUT AN EXPLODING SUNROOF (PANORAMIC) IS NOT SOMETHING ONE WOULD ANTICIPATE. THIS SHOULD NEVER HAVE HAPPENED - NOT EVEN ONCE - AND IS EXTREMELY DANGEROUS. *TR

I HAVE AN AUDI Q7 2010. JUNE 2013, MY HUSBAND, 4 YR OLD SON AND I WERE DRIVING ON THE FREEWAY GOING WITH THE FLOW OF TRAFFIC. THE CAR STARTED SHAKING VIOLENTLY AND DECELERATED TO 20 MILES PER HOUR. MY HUSBAND PUSHED THE GAS PEDAL OVER AND OVER AND THE CAR WOULD NOT SPEED UP. LUCKILY NO ONE WAS HURT, HOWEVER WE WERE VERY SCARED. WE WERE ABLE TO PULL TO THE EMERGENCY LANE AND MAKE IT TO THE AUDI DEALERSHIP CLOSE BY. JANUARY 2014, I WAS HEADING TO PICK UP MY SON FROM SCHOOL AND THE CAR STARTED SHAKING VIOLENTLY AGAIN- THIS TIME WORSE THEN BEFORE AND CAME TO A COMPLETE STOP IN THE MIDDLE OF TRAFFIC. THE STEERING WHEEL LOCKED UP AND I WAS STUCK. THE POLICE WERE CALLED BECAUSE I WAS NOT IN A SAFE PLACE AND THE CAR HAD TO BE TOWED TO THE DEALERSHIP. DEALER STATED THAT THEY FOUND FAULT IN THE FUEL SYSTEM, METAL SHAVINGS IN THE FUEL FILTER IN ADDITIONAL TO LOW FUEL PRESSURE. ALSO CONFIRMED METAL SHAVINGS IN THE N290 VALVE. THEY HAD TO GET AUTHORIZATION FROM GERMANY TO REPLACE ENTIRE FUEL SYSTEM. JULY 2014- YES IT HAPPENED AGAIN. THIS TIME MY HUSBAND AND SON WERE HEADED TO GO ON A FATHER-SON CAMPING TRIP AND RIGHT BEFORE THEY LOST ALL CELL SERVICE THE CAR STARTED VIOLENTLY SHAKING AGAIN AND DECELERATED. MY HUSBAND LEFT THE CAR IN A SAFE PLACE AND HAD FRIEND COME GET THEM. THE CAR IS A LEMON. I HAVE ASKED THAT AUDI AMERICA TO REPLACE THE CAR AND THEY SENT A TECHNICIAN TO THE DEALERSHIP WHO REPLACED THE FUEL FILTER AGAIN AND HAS DECIDED THE CAR IS REPAIRED AND SAFE TO DRIVE. THIS IS AFTER THE MANAGER OF THE SERVICE DEPARTMENT TOLD AUDI AMERICA THAT THE CAR IS NOT SAFE AND RECOMMENDED THEY REPLACE THE CAR. HE SAID " I WOULDN'T LET MY WIFE DRIVE YOUR CAR". THIS HAPPENED TO A FRIEND OF MINE WITH AN AUDI Q7 AND AUDI HAD TO BE FORCED TO AN ARBITRATION. SHE ENDED UP WITH A NEW DIESEL AND IT HAPPENED AGAIN! SHE IS NOW ON HER 3RD AUDI. THIS TIME NO DIESEL. *TR

1EA11003 · High-Pressure Fuel Pump Failure
Opened Feb 7, 2011 · Closed Mar 27, 2015
Status: closed (inferred from source dates) · Fuel System, Diesel; Fuel System, Other:delivery:fuel Pump
The Office of Defects Investgation (ODI) opened EA11-003 on February 7, 2011, based on 160 complaints to ODI and Volkswagen involving high pressure fuel pump (HPFP) failures in model year (MY) 2009 through 2010 Volkswagen Jetta and Golf and Audi A3 TDI vehicles and questions regarding fuel sample results provided by Volkswagen as part of its response to PE10-034.During EA11-003, ODI analyzed design information, field experience and test data for MY 2009 through 2012 Volkswagen Jetta, Golf and Touareg and Audi A3 and Q7 vehicles equipped with TDI engines. Volkswagen has not identified any design or manufacturing defects in the subject TDI Clean Diesel pumps and has stated that the subject pumps were designed, tested and approved for use in the United States market, with substantial design margins for fuels that are out of specification.Volkswagen believes that misfueling with gasoline is the primary cause of HPFP drivetrain failures in the field.Only the Q7 vehicles were built with misfuel protection devices.In May 2013 Volkswagen initiated a service campaign to install misfuel protection devices in all MY 2009 through 2012 Jetta, Golf and A3 vehicles.Volkswagen implemented misfuel protection devices in all of the subject models beginning in MY 2013. ODI?s analysis of HPFP drivetrain failure incidents indicates that most failures do not result in engine stall while driving and, when pump drivetrain failure does result in stall while driving, it is usually preceded by numerous warning symptoms (e.g., glow plug warning lamp, chime, limp mode, and driveability symptoms).The failure data for the subject vehicles show relatively low stalling rates (less than one percent at three years in service) for each of the pump designs used in the subject vehicles.There have been no reports of crashes, injuries or fatalities related to the alleged defect. Based on these facts, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.For additional information, see the closing report in the document file for EA11-003.
