Engine

13 reports
“Our 2015 Audi Q7 start using a lot of oil under 100,000 miles. Dealership replace turbocharger oil seals but that didn't fix the issue. The engine failed oil consumption test and was told the vehicle is safe to drive but will need to add oil every 1,000 miles. Engine failed three months later. Contact Audi of North American about the problem and ask about replacement engine because a vehicle of that type quality should not be having those type of issuea with low mileage.”

Fuel/propulsion system

8 reports
“Warranty will be over in 60 days; the Catalyst Coverter is going back, the Audi dealer and Audi Corporate are delaying the fixture do to some mis communication between dealer and corporate. The problem has to do with DEF gases not being cleanup. The error code is P20EE00 and the engine light is on. The part is under warranty and Audi Corporate is delaying the fixt because the do not wish to pay for the cost. They have had my vehicle for a full week and no decision when to replace the part. I strongly believe they want the warranty to expire so the customer has to pay for cost of the catalyst. The dealer has verified that part is under warranty but corporate does NOT response to the dealer.0”

Vehicle speed control

4 reports
“On 7/4 as I was merging onto the highway I was accelerating to merge onto the main lanes of traffic. I pressed on the accelerator to pickup speed, but when I let off the pedal the vehicle felt like it was continuing to accelerate similar to being on cruise control. I felt like I did not have control of the vehicle. I pressed on the brake pedal and let go to see if it would disengage the acceleration, but it did not. I then continued to press down on the brake pedal and pull over to the emergency lane and park the car. I had total of 6 passengers in vehicle with me, 4 adult and 2 children. After being pulled over I checked to insure the pedal was not stuck on any floor mats, and it was not. I was lucky that there was no traffic on the holiday to avoid any collisions. I carefully resumed to my destination and the vehicle operated normally. I reported to AudiUSA via online chat requesting advice. They suggested I contact a local service center who would charge me to diagnose the vehicle. I have not taken any steps yet given they typically will charge me regardless of determining any issues and identify some other upsell opportunity for service. I'm wondering if…”
