So I purchased a vehicle from wright drive in El Paso, Texas. I was driving home back to Alamogordo which is 90 miles away, maybe 80 I realized there was no adaptive cruise control. So I messaged dealership. They told me that there was nothing they could do. It's not a safety issue. I got the vehicle home the next day. I found out the whole front suspension was bad. I kept hearing a noise when I would drive over bumps and it was really loud. I contacted the dealership, told them that the suspension was bad. They told me to take it to Audi to have them look at it. It came out to like $8,000…

I BROUGHT THIS ISSUE UP MY LOCAL AUDI DEALERSHIP AND THEY HAVE ACTED AS IF THEY WERE TOTALLY UNAWARE OF THIS ISSUE. ALSO I KEEP GETTING LOW PRESSURE IN MY FROM RIGHT TIRE, THIS KEEPS ME FROM BEING ABLE TO DRIVE LONG DISTANCES AS I AM MILITARY STATIONED IN AN ISOLATED AREA. *TR
ON THREE SEPARATE OCCASIONS, THE VEHICLE DID NOT STOP WHEN THE BRAKE PEDAL WAS PUSHED AT HIGHWAY DRIVING SPEEDS. THIS DOES NOT HAPPEN ALL THE TIME. CAR HAS BEEN TOWED TO AUDI DEALERSHIP TWICE, YET THEY FIND NOTHING WRONG WITH THE VEHICLE BECAUSE THE DIAGNOSTIC TESTS THAT THEY ARE RUNNING RELY ON THE COMPUTER, WHICH IS DEFECTIVE TO BEGIN WITH AND NOT RECORDING THE NECESSARY FAILURE (CODES) FOR WHEN THE BRAKES FAIL ON THE VEHICLE. WE HAVE NO CHOICE BUT TO CONTINUE DRIVING THE PER AUDI DEALERSHIP (OPEN ROAD / AUDI MANHATTAN) UNTIL LEASE END.
WHEN BRAKING THE CAR VIBRATES, SOMETIMES SO VIOLENTLY THAT IT IS UNSAFE TO KEEP APPLYING THE BRAKES TO CONTROL THE SPEED OF THE VEHICLE. CURRENTLY THE VEHICLE HAS BEEN IN SERVICE SINCE JUNE 27, 2015 AND HAS BEEN DRIVEN 21,000 MILES. HOWEVER, THIS VIBRATION HAS BEEN NOTICED EARLY IN THE LIFE OF THE CAR. ORIGINALLY, I THOUGHT THE VIBRATION WAS DUE TO THE ROAD SURFACE OR CONDITION, BUT I HAVE COME TO REALIZE THAT THIS PROBLEM IS A VEHICLE FAULT. IN THE MOST RECENT INCIDENT WE WERE DRIVING FROM PAYSON, ARIZONA TO MESA, ARIZONA USING THE VEHICLE CRUISE CONTROL. ON THIS ROAD, US 87, THERE ARE A FEW…
I WAS DRIVING ON A SUBURBAN CITY STREET IN A STRAIGHT LINE WITH NO CARS OR ANY OTHER OBSTRUCTIONS AHEAD OF ME OR BEHIND ME. WITHOUT WARNING, THE CAR ENGAGED ITS EMERGENCY BRAKING THROWING MY DAUGHTER AND ME FORWARD VIOLENTLY INTO OUR SEAT BELTS. WHEN I FELL BACK, THE DASHBOARD WAS SHOWING ME A PROXIMITY WARNING BUT AGAIN NOTHING WAS ANYWHERE NEAR OUR CAR. THE SERVICING DEALER SAID THEY DIDN'T FIND ANY ERROR CODES AND SO THERE WAS NOTHING THEY COULD DO. THIS HASN'T HAPPENED AGAIN (YET) BUT THE CAMERAS ALL AROUND THE CAR THAT ENGAGE FOR PARKING AND IN REVERSE ARE CONSTANTLY GOING OUT AND/OR THE…
TL* THE CONTACT OWNS A 2015 AUDI A8. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 60 MPH, THE VEHICLE SPEED DECREASED AND SUDDENLY FAILED TO GO OVER 40 MPH. IN ADDITION, WHEN DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE STALLED. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER BUT THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 10,427.
CAR VIBRATES AT ALMOST ANY SPEED OTHER THAN IDLE. I HAVE HAD THE CAR BACK TO THE DEALER SEVERAL TIMES. THE VIBRATION CAN BE FELT THROUGH THE STEERING WHEEL, THE SEATS AND ON THE DASHBOARD. I CAN'T GET THE CAR FIXED. I HAVE ASKED AUDI TO REPLACE THE CAR IF THEY CAN'T FIX IT. NO RESPONSE. I HAD 5 AUDI A8'S IN THE PAST AND NEVER EXPERIENCED ANY SUCH PROBLEM I AM ALMOST AFRAID TO DRIVE THE CAR. I LEASED THE CAR FOR 15,000 MILES PER YEAR AND ONLY HAVE 7800 MILES IN 11 MONTHS BECAUSE OF THIS FEAR.
