NOTICED AIR BAG LIGHTS ON DIDNT THINK QUICK , ALSO I NOTUCED ELECTRICAL ISSUE HERE & THERE. ENGINE RUNS & SOUNDS LOUDER WHEN USING A/C. WHEN YOU GO TO SHUT OFF VEHICLE THERES A LOUD THUMP THUMP NOISE AT THE END FIR ABOUT 3 MINS OR SO , PROBLEMS STARTING THE ENGINE , BACK WINDSHIELD WIPER TURNS ON BY ITS SELF , A WEEK AGO THE LIGHT IN THE BAVK TURNS ON BY IT SELF. OTHER ENGINE PROBLEMS NOT SURE IF ALL TIED IN TOGETHER I JUST STARTED MY PURCHASE ON 7/21/2020 FROM A CAR DEALER. HAD IT CHECKED BY 2 PEOPLE & ONE SAID AIR LEAK SHOWING FROM DIAGNOSTIC MACHINE . MY DEALER PUT ON MACHINE & SAID DIDNT SEE NOTHING WRONG. POWER STEERING GOES OUT HAVE TO FILL ALMOST EVERY 2-3 DAYS. MY DEALER SAID DONT PUT MORE CAUSE IT COULD MESS UP ENGINE. SO I DIDNT & 2 DAYS LATER DRIVING 15 -20 MPH ON RESIDENTIAL STREET IT STARTS SOUNDING LIKE ITS GOING TO STOP SO I PRESUMED TO SHUT OFF ENGINE . CHEVK UNDER THE HOOD & THE POWER STEERING FLUID WAS BONE DEY SMOKING SLIGHTLY , & BELT WAS PULLED OUT A& SHREDDED & IT WOULDNT EVEN TURM ON ENOUGH TO GET A FULL START & DEALER CAME & TOWED IT BACK. NOW HE SAYING I NEED A NEW ENGINE
'TAKATA RECALL' I MADE APPOINTMENTS AND REGISTERED TO GET MY AIRBAG REPLACED ON NUMEROUS OCCASIONS. IN JUNE I MADE AN APPOINTMENT AT THE ELMWOOD PARK LOCATION AND WHEN I GOT THEIR THE GUY LIED AND SAID THE COMPUTERS ARE DOWN HE DIDN'T WANT TO HELP ME. THEY HAVE THE PARTS AVAILABLE AND DON'T WANT TO FIX IT IT IS NOW 2018 AND NO ONE FROM AUDI CALLED ME AND MY VEHICLE IS REGISTERED WITH THEM. SO MY AIR BAG CAN RUPTURE AT ANY TIME I WAS IN A CAR ACCIDENT ON 1/4/17 I WAS INTENTIONALLY REAR ENDED BY A WHITE BMW AND I WAS IN THE CAR WITH MY 8 YEAR OLD NEPHEW AND MOM WHO WAS IN THE FRONT PASSENGER SEAT I COULD HAVE BEEN KILLED AND SERIOUSLY INJURED. NOT ONLY THAT MY GAS TANK FUEL INJECTOR THE AIR PRESSURE IS OFF CAUSING IT TO STOP CONSTANTLY WHILE GETTING GAS. THIRD I HAD THIS P2005 AND P2006 ERROR CODE WHICH IS THE INTAKE AIR EXCHANGE MANIFOLD FLAP CHECK ENGINE LIGHT ON WHICH IS A MANUFACTURING ERROR WHEN I WENT TO GET IT REPLACED COSTING ME 1,800 THE LIGHT IS STILL ON AND THE SAME ERROR CODE IS BACK 2 MONTHS LATER NOTHING WAS FIXED ON MY CAR PERIOD AND ON 10/31/17 I WENT TO AUDI IN UPPER SADDLE RIVER AND THEY DID NOT FIX IT EITHER OF FIND A DEALER WITH THE AIRBAG NEAR BY THAT HAS THE PARTS TO REPLACE IT THO COULD HAVE COST ME AND MY PASSENGERS THEIR LIFE AND THIS ISN'T UNACCEPTABLE FOR AUDI TO TREAT CUSTOMERS LIKE THAT REGARDLESS OF MY VEHICLE BEING OLD NEW OR BROUGHT FROM A THIRD PARTY DEALERSHIP ALL AUDI OWNERS SHOULD BE TREATED EQUALLY AND REMEDIES BE ADDRESS ACCORDING TO LAW AND RECALL. BEING THAT A SAFETY RECALL IS ISSUED CUSTOMER PREFERENCE IS NULL AND VOID BECAUSE SAFETY AND WEALTH HAS NO BEARING IN WHO GETS FIRST DIBS ON AIRBAGS NO AUDI OWNER SHOULD GET PREFERENCE OVER THE OTHER WHETHER IT BE THEY BROUGHT THEIR CAR DIRECTLY FROM THE AUDI DEALERSHIP OR NOT AND THAT THE IMPRESSION I'M GETTING AND BASED ON MY EXPERIENCE NOT ALL CUSTOMERS AND OWNER ARE TREATED EQUALLY
TAKATA RECALL WATER PUMP IS BAD AN IT IS ON THE RECALL LIST
TL* THE CONTACT OWNS A 2005 AUDI A4. WHILE DRIVING AT 35 MPH, "LOW OIL PRESSURE, TURN ENGINE OFF AND PULL OVER" WAS DISPLAYED ACROSS THE MESSAGE BOARD. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE OIL PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 118,000. UPDATED 04/06/16*LJ UPDATED 11/3/2017*JS
DRIVING DOWN THE ROAD AND MY CAR STARTS SMOKING AND CATCHS ON FIRE
STOPPED ON A HILL AT A STOP LIGHT, WENT TO GO AND CAR LUNGED FORWARD AND DIED. HAD TO IMMEDIATELY APPLY BRAKES, CAR STARTED AGAIN. HAS HAPPENED MULTIPLE TIMES. WE ARE SECOND OWNER, HAVE ONLY HAD THE CAR FOR A YEAR AND FOUND THAT THE TRANSMISSION CONTROL MODULE FOR THIS VEHICLE WAS ALREADY REPLACED AT 49,000 MILES - UNDER WARRANTY TO OTHER OWNER. NOW, AT 130K MILES WE ARE BEING TOLD IT HAS TO BE REPLACED AGAIN. IT IS A DANGER TO DRIVE AS THEY SAID THE TRANSMISSION COULD FAIL OR EVEN THE GEARS COULD SLIP CAUSING DANGER TO THE PASSENGERS. THIS PARTICULAR MODEL OF AUDI TRANSMISSION, KNOWN AS "MULTITRONIC" OR "CVT" HAS NUMEROUS COMPLAINTS AND FAILURES. WE PAID 12K FOR THIS CAR USED AND HAVE A MAJOR MALFUNCTION WITHIN A YEAR. *TR
SHIFTING FROM SECOND TO THIRD GEAR AND THE GAS PEDAL WENT DOWN TO THE FLOOR AND ENGINE REDLINED RPMS. I HAD TO MANUALLY PULL THE PEDAL FROM THE FLOOR WHERE THE ENGINE AND PEDAL FUNCTIONED AS NORMAL AFTERWARDS. I CHECKED THE FLOOR MAT AND IT WAS SECURE AND AWAY FROM IMPEDING THE PEDAL. *TR
CAN'T STAR AND EPC LIGHT ON. *TR
THE TIMING CHAIN (NOT THE TIMING BELT, WHICH HAD BEEN CHANGED WELL BEFORE THE RECOMMENDED TIME) BROKE. THIS CAUSED THE ENGINE TO SEIZE IMMEDIATE RESULTING IN THE CAR COMING TO A RAPID AND ABRUPT STOP. FORTUNATELY FOR ME, IT OCCURRED AT LOW SPEED ON A VERY QUIET STREET. HAD IT OCCURRED ON A FREEWAY, SERIOUS INJURY OR DEATH LIKELY WOULD HAVE RESULTED SINCE THE CAR DECELERATED SO QUICKLY I WOULD NOT HAVE HAD TIME TO COAST INTO THE BREAKDOWN LANE. APPARENTLY FAILURES OF THESE TIMING CHAINS OCCUR COMMONLY; AUDI APPARENTLY HAS AN EXTENDED WARRANTY PROGRAM FOR SOME CAM FOLLOWER WEAR PROBLEMS (THAT MAY OR MAY NOT INVOLVE A TIMING CHAIN FAILURE). BUT THEY DO NOT LIST THE CHAIN OR THE FOLLOWER AS MAINTENANCE OR INSPECTION ITEMS, AND GIVE OWNERS NO HINT THAT THEY SHOULD INSPECT THE FOLLOWER, OR REPLACE THE CHAIN PERIODICALLY. TIMING CHAIN FAILURES ON ZERO CLEARANCE ENGINES (VW HAS THE SAME ENGINE AND APPARENTLY THE SAME PROBLEM), WILL KILL FOLKS IF THEY OCCUR ON FREEWAYS OR OTHER ROADS WHERE AN INABILITY TO COAST TO A SAFE STOPPING POINT WILL LEAVE MOTORISTS AT INCREDIBLE RISK. *TR
TL*THE CONTACT OWNS A 2005 AUDI A4 2.0T. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 60 MPH, THE VEHICLE SUDDENLY LOST POWER WITH NO POWER BRAKES OR POWER STEERING. THE CONTACT COASTED TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS INFORMED THAT THE CAM SHAFT BROKE AND THE ENTIRE ENGINE NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED. THE CONTACT CALLED THE MANUFACTURER WHO OFFERED TO COVER A PERCENTAGE OF THE REPAIR. THE VIN WAS UNAVAILABLE WHEN THE COMPLAINT WAS FILED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 70,000.
TL*THE CONTACT OWNS A 2005 AUDI A4. THE CONTACT RECEIVED A NOTICE STATING THAT THE VEHICLE WAS RUNNING ON THREE CYLINDERS. THE DEALER STATED THAT THERE WAS NO REASON FOR CONCERN AND THAT THE VEHICLE WOULD BE FINE. THE DEALER REPLACED THE ENGINE COIL IN ORDER TO REDUCE THE AMOUNT OF GASOLINE THAT WAS BEING USED. THREE MONTHS LATER THE TURBO FAILED AND THE ENGINE MALFUNCTIONED. THERE WERE NO WARNING LIGHTS ILLUMINATED WHEN THE FAILURE OCCURRED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 62000.
PRIOR TO STALLING, THE ENGINE WAS MAKING A LOW NOISE, WHICH I HAVE HEARD BEFORE AS A NORM ON COLD DAYS TO WARM UP. *TR
I PURCHASED CERTIFIED PRE OWNED CAR FROM DEALERSHIP-AUDI A4 3.0 QUATTRO, 2005. 2 DAYS LATER I COULD NOT PASS REQUIRED STATE INSPECTION DUE TO "CHECK ENGINE" ISSUE-MISFIRE ON A 6TH CYLINDER. I BROUGHT THE CAR BACK TO DEALERSHIP A FEW DAYS LATER TO CORRECT THE PROBLEM. THE PROBLEM WAS CORRECTED TEMPORARILY AND CAR PASSED THE INSPECTION-'CHECK ENGINE' LIGHT WAS RESET BY DEALERSHIP. A FEW MONTHS LATER "CHECK ENGINE" ISSUE CAME BACK AFTER SCHEDULED MAINTENANCE (AT 50,000 MILES) WAS DONE BY AUTHORIZED DEALERSHIP. PROBLEM WAS TEMPORARILY CORRECTED 2ND TIME. IN DECEMBER 2008 AFTER 3RD TIME "CHECK ENGINE" ISSUE, DEALERSHIP PROPOSED TO REPLACE WHOLE ENGINE IN ORDER TO RESOLVE THIS ISSUE, WHICH WAS DONE. ON FEBRUARY 11, 2009 DRIVING BACK HOME FROM WORK I'VE NOTICED AN EXHAUST GAS SMELL INSIDE THE CAR, CAR WAS SHAKING AND "CHECK ENGINE " LIGHT WAS "ON"/NOT STEADY. I CONTACTED AUDI CUSTOMER SERVICE ADVOCATES TO REPORT THE PROBLEM AND START THE CASE. I BROUGHT THE CAR BACK TO DEALERSHIP FOR REPAIR 4TH TIME. THEY PERFORMED NECESSARY STEPS TO CORRECT THE PROBLEM BUT FAILED (2 SENSORS WERE REPLACED ACCORDING TO THEM AND "CHECK ENGINE" LIGHT STILL "ON"). I WAS INFORMED THAT DEALERSHIP DID NOT REPLACE THE WHOLE ENGINE BACK IN DECEMBER 2008 - THEY ONLY REPLACED LOWER PART OF THE ENGINE KNOWING THAT THERE WAS A PROBLEM WITH MISFIRE ON 6TH CYLINDER (UPPER PART OF THE ENGINE). AFTER 3 WEEKS OF WAITING AND CONSTANT REPAIRS I AM NOT SURE THAT THIS PROBLEM HAS BEEN CORRECTED PERMANENTLY. FACTS: CAR WAS PURCHASED AT 49,000 MILES ON APRIL 29, 2008. MY CAR HAS BEEN AT DEALERSHIP FOR 75-80 DAYS OUT OF 10 MONTHS SINCE I PURCHASED IT. TOTAL MILEAGE AS OF FEBRUARY 28, 2009 IS 52,450. *TR
TL*THE CONTACT OWNS A 2005 AUDI A4. WHILE DRIVING 2-5 MPH IN REVERSE, THE VEHICLE WOULD NOT ACCELERATE AND THE ENGINE WARNING INDICATOR LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY STATED THAT THE COIL THAT DISTRIBUTES SPARK TO THE CYLINDERS DEGENERATED AND LOST POWER. THE DEALER REPLACED FOUR IGNITION COILS. THE CURRENT AND FAILURE MILEAGES WERE 52,000.
2005 AUDI A4 AVANT IS CURRENTLY STILL UNDER WARRANTY BUT THE AUDI DEALERSHIP AND AUDI OF AMERICA WILL NOT REPLACE A CRACKED COOLANT RESERVOIR. THE ONBOARD COMPUTER CAME ON, INDICATING A PROBLEM, BUT THERE WAS NO LEAK. HOWEVER, THE CRACK WAS VERY VISIBLE AND WILL MOST LIKELY SPREAD FURTHER RESULTING IN A LEAK. THE CRACK WAS MOST LIKELY CAUSED FROM THE EXCESSIVE HEAT UNDER THE ENGINE HOOD. I BELIEVE THIS WAS A SERIOUS FLAW IN MATERIALS USED TO MANUFACTURE THE RESERVOIR. *AK
DT: THE CONTACT OWNS A 2005 AUDI A4 2.0 LITER TURBO ENGINE. THE NON LINEAR ACCELERATION, IT WILL BOG AND SURGE WHILE IN TRAFFIC. WHILE PRESSING HARD ON THE GAS, IT WILL SUDDENLY SURGE FORWARD, CAUSING DRIVERS BEHIND HIM TO CONSTANTLY APPLY THE BRAKES. ALSO, THE LOW SPEED POWER STEERING WILL NOT COME ON. IT WAS LIMITED AND VERY HARD TO STEER. THIS PROBLEM WITH THE POWER STEERING STARTED INTERMITTENTLY. THE CONTACT'S VEHICLE WAS INVOLVED IN AN ACCIDENT. BUT BECAUSE OF THE LACK OF POWER STEERING ACCELERATION PREVENTED FROM BEING HIT. THE VEHICLE HAS BEEN AT THE DEALERSHIP FIVE TIMES FOR THE ACCELERATING PROBLEM, AND ONCE FOR THE POWER STEERING PROBLEM. THE DEALERSHIP HAS NOT CORRECTED THE ACCELERATION PROBLEM. THE DEALERSHIP STARTED A DIAGNOSTIC TEST ON THE POWER STEERING. THE CONTACT CONTACTED THE MANUFACTURER MANY TIMES, AND THEY WERE COOPERATIVE. THE REPAIRS ARE BEING DELAYED BECAUSE THE DEALERSHIP FORGOT TO ORDER THE PARTS. THE NUMBERS OF FAILURES WERE 100 TIMES AT LEAST. THE PROBLEMS FIRST BEGAN 10 DAYS AFTER PURCHASE OF THE VEHICLE ON APRIL 4, 2005, AND IT WAS IN FOR SERVICE ON APRIL 14, 2005. THE CONSUMER WAS TOLD THE BOG AND SURGE WAS WITHIN AUDI'S SPECIFICATIONS AND NO CORRECTIVE ACTION WOULD TAKE PLACE. 11/15/05. *JB
