Engine

“Yet another beautiful Audi 3.0tfsi with the rocker arm failure … how is there not a class action lawsuit already ? I have a knock in my valve train and I just bought this car two days ago …. Audi should be liable to fix this because I didn’t know nothing about this and with a quick search it’s alike a epidemic of the same problem..”

Service brakes

4 reports
“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.”

“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 worth of repairs. They told me they would not pay that and I could return the vehicle for a full refund. I told them okay. I would be there in 3 days because I was working. They said that was fine. I get there 3 days later they told me that was no longer an option. So I got stuck with the car that needed $8,000 worth of repairs and then another four for more suspension parts. New breaks the 3,000 to fix the adaptive cruise control. I understand the adaptive cruise control is not really a big deal but the fact that they lied about me being able to return the vehicle and now…”

“I HAVE OWNED MY 2015 AUDI 8L FOR 6 MONTHS AND IT HAS STARTED TO STALL WHENEVER I START THE INITIATION BUTTON. OFTEN TIMES IT WILL JUST SHIFT OFF CAUSING ME TO HAVE TO RESTART IT MULTIPLE TIMES. 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”
