I am interested in buying a Q7. I would like to know about maintenance and know issues.

How many miles per oil change and average cost?
How many miles before brake/rotor change? Cost?
How hard is it on tires? Avg mile per set?

What other issue is common to the Q7 and average cost for repair.

What are the schedule maintenance intervals and what's the cost? What's done at the intervals?

 

Regarding scheduled maintenance, the first is at 5,000 miles. Then I believe at 15,000, and every either 10,000 or 15,000 after that. I recommend getting Audi Care, which is essentially paying in advance for the first several services at a discount.

Consult Edmunds or Consumer Reports for more.
