“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.…”
“Common problem with engine cooling systems and oil systems failing. Failing emissions because of this and overheating with risk of fire. Common problem with the Q5s. Which some of them are recalled but not my 2015 q5 premium for some reason.”
“I've reported multiple times to my dealer about the oil comsumption back in 2022 and work was performed on the vehicle in the prior year to fix leak and brake noise issue since approx 2021 on my 2015 Q5 that currently only has 65,000 miles. No warning indicator presents regarding the brakes. However oil indicator and engine light icons display. I'm constantly checking the oil indicator level to see how much is still in the and then add add once it shows thats its extremly low. I have to do this everytime I am about to use the car. This can be dangerous at times since there's no indication that its very low and its not seen unless you go into the "car" section that shows the level, it has no alert display for the level. All required diagnostic and maintenance services have been performed with the dealer. When inspecting the brake issue they always come back with no findings say that no issue could be found, howeve when I'm driving it, it sqeeks and makes a grinding sound all the time. This has been going on for quite a few years. As for the oil consumption issue, this isssue has been in recent years and both times this has been looked into by the dealer I was…”
“After paying to run an inspection test recommended by Audi USA, it was confirmed that the issue of the excess oil consumption was with the piston, and they also recommended changing the engine. It puts me at risk every time I drive the car because I am not sure how much oil my car has at this point. I have been reporting to the dealer my observation of excessive oil consumption. They kept telling me that it was because my car was old. I have an Audi Q5 2015 with 85,600 miles. I have done all my manufacturing maintenance at the dealer, so they have records that I do take care of my car. I paid to run a diagnostic test suggested by Audi USA. I was told that I have to pay about $30,000 to fix the engine ($13,000 + for the piston and $17,000 + for the engine). The car started warning me that it needed oil soon. I reported it to Audi USA and told them that this issue was one of the recalls done in 2017. I was told that I did not qualify for any coverage because it was only for cars that had an issue in 2017. Now, at 85,600 miles, I am using almost two-quarters of an ounce for every 1,000 miles. I called Audi USA over a month ago, and they asked me to take my car to…”
“Cylinder #3 lost compression, down to 30 psi from 170 psi, causing the car to lose power and run extremely rough or not run on occasion. This is a safety hazard, especially risky for highway driving. There were no warning messages, car just start running very rough or wouldn't start. Such loss of compression has been reported by an Audi service manager who says Cylinder #3 is known to have this issue, but there is no recall for it yet. The problems began in May 2021. The car was drinking/consuming oil frequently and occasionally running rough. It was taken to multiple mechanics to identify the issue. Fixes included changing spark plugs, coils, and the PCV valve to provide temporary solutions at best. 5/24/21 increased consumption of oil began 9/9/22 rough idle, spark plugs replaced 10/14/22 rough idle and burning oil, taken to a service shop, replaced the PCV valve 7/12/23 rough idle again, spark plugs replaced again under warranty 2/14/24 - rough shake again, spark plugs replaced again and dead cylinder #3 confirmed”
“The contact owns a 2015 Audi Q5. The contact stated that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to a dealer where it was discovered that oil had leaked into the engine coolant. Due to the failure, the oil cooler was replaced; however, the failure persisted. The vehicle was taken back to the dealer where an oil consumption test was performed. The test showed that the piston rings were defective and needed to be replaced. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 75,000.”
