“Vehicle: 2015 Audi Q5 2.0T VIN: [XXX] At around 70,000 miles, my vehicle began consuming engine oil abnormally. I received a low-oil warning and had to add 1 quart every 1,000 miles. I first approached an authorized Audi dealer at 75,000 miles, who inspected the vehicle and stated this was “normal for older vehicles” and found no issues. However, the problem worsened rapidly. By 79,000 miles, I visited a second Audi dealer who acknowledged that this was a common problem in this engine type. They quoted me $16,000–$20,000 for a full engine replacement, stating they could not replace pistons alone. At 80,000 miles, my car now consumes 1 quart of oil every 200 miles. The oil warning light comes on frequently. I am forced to carry oil and top off multiple times per week. This is not normal wear for a luxury vehicle with regular maintenance. This condition creates multiple safety risks: •Sudden engine seizure or power loss if oil runs too low, especially while driving at highway speeds. •Loss of steering/brake assist due to oil pressure failure. •Increased fire risk from leaks or overheating. •Frequent roadside stops to add oil, risking exposure to traffic.…”
